As shown in FIG. 1, the bathroom unit 10 includes a floor panel 11, a side wall panel 12, a bathroom ceiling unit 20, and a bathtub 13. The bathroom ceiling unit 20 includes a first ceiling panel 40 and a second ceiling panel 50 that are members constituting the ceiling 30 of the bathroom unit 10. The bathroom unit 10 constitutes a bathroom 14. The bathroom 14 is a space surrounded by the floor panel 11, the side wall panel 12, the first ceiling panel 40, and the second ceiling panel 50. The bathtub 13 is disposed in the bathroom 14.

  The floor panel 11 includes a drain port 11A. The drain 11 </ b> A is provided next to the bathtub 13. The surface of the floor panel 11 is inclined with respect to the surface of the ceiling panels 40 and 50 on the bathroom 14 side. In the illustrated example, the surface of the floor panel 11 is inclined so as to become lower toward the bathtub 13 from the side wall panel 12 away from the bathtub 13. Concavities and convexities 11B that enhance drainage are formed on the surface of the floor panel 11.

  The ceiling panels 40 and 50 are made of a metal material. The surfaces of the ceiling panels 40 and 50 are coated with resin. The first ceiling panel 40 includes an inspection port 43. The shape of the inspection port 43 is elliptical in plan view of the first ceiling panel 40 (see FIG. 3). The inspection port 43 passes through the first ceiling panel 40. For this reason, the bathroom 14 and the back side of the first ceiling panel 40 are connected by the inspection port 43. The size of the inspection port 43 is, for example, a size that allows an operator to pass through. The inspection port 43 is provided in the first ceiling panel 40 so that the center of the inspection port 43 does not coincide with the center of the ceiling 30 in a plan view of the first ceiling panel 40.

  FIG. 2 is an exploded perspective view of the bathroom ceiling unit 20 excluding the second ceiling panel 50. The bathroom ceiling unit 20 further includes a lid unit 60 in addition to the ceiling panels 40 and 50. The lid unit 60 has a function of closing the inspection port 43 and a function of outputting sound information into the bathroom 14 (see FIG. 1). The shape of the lid unit 60 is elliptical (see FIG. 3). The lid unit 60 includes a lid 61, a vibrator 66, and a control device 70. The function of the vibrator 66 is to vibrate the lid 61 so that sound information is output to the bathroom 14. The vibrator 66 and the lid 61 constitute a speaker.

  The lid 61 includes a flange portion 61 </ b> A and includes an upper lid 62 and a lower lid 63. The flange portion 61 </ b> A protrudes from the outer peripheral portion of the lid 61 toward the outer side in the radial direction of the lid 61. The upper lid 62 includes a flange piece 62A and a plurality of grooves 62B. The plurality of grooves 62 </ b> B are provided in the upper lid 62 in order to increase the strength of the lid 61. The lower lid 63 includes a flange piece 63A. The flange 61A of the upper lid 62 and the flange piece 63A of the lower lid 63 are connected by a plurality of bolts 65 to form the lid 61 (see FIG. 4). Each flange piece 62A, 63A constitutes a flange portion 61A of the lid 61. The lid 61 further includes an accommodation space 64 surrounded by the upper lid 62 and the lower lid 63. The vibrator 66 and the control device 70 are disposed on the upper surface of the lower lid 63 so as to be accommodated in the accommodation space 64. In one example, the vibrator 66 is provided at the center of the lid unit 60 in a plan view of the lid unit 60.

  The flange portion 61 </ b> A constitutes the outer peripheral portion of the lid unit 60. The outer peripheral portion of the lid unit 60 overlaps with the first ceiling panel 40 in the vertical direction of the bathroom unit 10 (see FIG. 1), and is supported by the first ceiling panel 40. The lid unit 60 closes the inspection port 43 by being supported by the first ceiling panel 40.

  FIG. 4 shows a cross-sectional structure in a state where the lid unit 60 closes the inspection port 43. The lid unit 60 further includes a first elastic member 67 and a second elastic member 68. The function of the first elastic member 67 is to suppress sound information output from the lid unit 60 from leaking to the back side of the ceiling 30 (see FIG. 1). The first elastic member 67 is disposed between the upper lid 62 and the vibrator 66 and is sandwiched between the upper lid 62 and the vibrator 66. The function of the second elastic member 68 is to suppress the vibration of the lid unit 60 from being transmitted to the first ceiling panel 40. The second elastic member 68 is attached to the bottom surface 61C (see FIG. 5) of the flange portion 61A.

  The bathroom ceiling unit 20 further includes a reinforcing member 80. The reinforcing member 80 is, for example, a gypsum board. The function of the reinforcing member 80 is to reinforce the first ceiling panel 40. The reinforcing member 80 is installed on the upper surface of the first ceiling panel 40 that is the surface on the back side of the first ceiling panel 40. The reinforcing member 80 or another reinforcing member (not shown) having substantially the same configuration as the reinforcing member 80 is installed on the entire upper surface of the second ceiling panel 50.

  FIG. 5 shows a support structure of the lid unit 60 by the first ceiling panel 40. The first ceiling panel 40 includes a panel body 41 and a support body 42. The panel body 41 and the support body 42 are made of the same material. The support body 42 is formed integrally with the panel body 41. In one example, the support 42 is formed by bending an end portion of one metal material.

  The panel body 41 is a part constituting the surface of the first ceiling panel 40 on the bathroom 14 (see FIG. 1) side. The reinforcing member 80 is attached to the upper surface of the panel body 41. The panel body 41 includes a covering portion 41A and an elastic portion 41B. The covering portion 41A and the elastic portion 41B are continuous. The covering portion 41 </ b> A is a portion covered with the reinforcing member 80 in the panel body 41. The elastic part 41 </ b> B is the inspection port 43 in the panel body 41 and its surrounding part, and is a part that can be bent with respect to the covering part 41 </ b> A because it is not covered with the reinforcing member 80. The reinforcing member 80 has a through hole 80A so as not to cover the elastic portion 41B. The lid unit 60 is supported by the support 42 so that it can be displaced in the vertical direction with respect to the first ceiling panel 40 as the elastic portion 41B is bent and deformed. The bending deformation of the elastic part 41B is elastic deformation.

  The function of the support 42 is to support the lid unit 60 in a state in which the lid unit 60 can be displaced with respect to the first ceiling panel 40. The support 42 is provided on the edge 43 </ b> A of the inspection port 43 so as to surround the inspection port 43. The shape of the support 42 in a plan view of the first ceiling panel 40 is an ellipse similar to the shape of the lid unit 60 and the shape of the inspection port 43 (see FIG. 3). The support body 42 is provided so as to rise from the edge 43A of the inspection port 43 in the elastic portion 41B to the lid unit 60 side, and supports the bottom surface 61C of the flange portion 61A via the second elastic member 68. The support body 42 includes a bent portion 42A. The bent portion 42A is a portion bent so that the support 42 is curved. The support body 42 is configured by, for example, being bent so that the bent portion 42A faces upward. The bent portion 42A supports the bottom surface 61C of the flange portion 61A via the second elastic member 68.

  When the second elastic member 68 is supported by the support body 42, the second elastic member 68 and the support body 42 come into close contact with each other, and moisture such as moisture in the bathroom 14 enters the back side of the first ceiling panel 40. To be prevented. The second elastic member 68 also functions as a packing.

  In the planar direction of the lid unit 60, the support 42 and the outer peripheral surface 63B of the lower lid 63 are opposed to each other with the first space S1 therebetween. In the planar direction of the lid unit 60, a second space S2 is provided between the inner peripheral surface 80B of the reinforcing member 80 that forms the through hole 80A and the outer peripheral surface 61B of the flange portion 61A that faces the inner peripheral surface 80B. It is done. The first distance L1 that is the distance from the root of the support body 42 to the inner peripheral surface 80B of the reinforcing member 80 is longer than the second distance L2 that is the distance from the root of the flange portion 61A to the tip of the flange portion 61A. . The first distance L1 corresponds to the length of the elastic portion 41B in the planar direction of the lid unit 60.

  The amount of bending of the elastic portion 41 </ b> B affects the followability of the support 42 with respect to the lid unit 60. When the amount of bending of the elastic portion 41B is included in the predetermined bending range, preferable followability is obtained. The first distance L1 corresponds to one of the main factors that affect the amount of bending of the elastic portion 41B. In one example, the first distance L1 is set to a length within a predetermined distance range, so that the bending amount of the elastic portion 41B is included in the predetermined bending range. The first distance L1 further corresponds to one of the main factors that affect the rigidity of the elastic portion 41B. In one example, the rigidity of the elastic portion 41B is included in the predetermined rigidity range by setting the first distance L1 to a length within the predetermined distance range. The predetermined stiffness range is a stiffness range in which the elastic portion 41B does not substantially deform toward the bathroom 14 (see FIG. 1) when the weight of the lid unit 60 acts on the elastic portion 41B in a state where the lid unit 60 is not vibrating. It is. In this way, by setting the first distance L1 to a length within the predetermined distance range, preferable followability of the support body 42 and preferable rigidity of the elastic portion 41B are ensured.

  The vibrator 66 shown in FIG. 2 is electrically connected to the control device 70. The function of the control device 70 is to vibrate the vibrator 66 based on a signal received from an external device such as a controller (not shown). The signal output from the external device includes information regarding sound. The controller can communicate with the control device 70 by wire or wirelessly. The control device 70 includes an amplifier (not shown) that amplifies the signal received from the controller. The control device 70 is driven by electric power supplied from an external power source (not shown) or the like, and vibrates the vibrator 66 based on a signal received from the controller.

The operation of the bathroom ceiling unit 20 will be described with reference to FIGS.
The controller of the bathroom ceiling unit 20 outputs a signal in response to a user operation. In one example, the signal includes information about sound. The control device 70 (see FIG. 2) vibrates the vibrator 66 (see FIG. 2) based on the signal received from the controller.

  FIG. 6 shows a state where the lid unit 60 is displaced downward with respect to the first ceiling panel 40. When a force that causes the lid unit 60 to be displaced downward relative to the first ceiling panel 40 is applied from the vibrator 66 to the lid 61, the force is transmitted from the lid unit 60 to the support 42. For this reason, the elastic part 41B bends so that the support body 42 is displaced downward with respect to the covering part 41A, and the lid unit 60 is displaced downward with respect to the first ceiling panel 40. Thus, since the lid unit 60 is displaced downward while bending the elastic portion 41B, the support 42 follows the displacement of the lid unit 60, and a gap is not easily formed between the lid unit 60 and the support 42. The sound information output from the lid unit 60 is less likely to contain noise.

  FIG. 7 shows a state in which the lid unit 60 is displaced upward with respect to the first ceiling panel 40. After the elastic portion 41B is elastically deformed downward, when a force for displacing the lid unit 60 upward relative to the first ceiling panel 40 is applied from the vibrator 66 to the lid 61, the elastic portion 41B is covered with the covering portion 41A. In contrast, the support 42 is bent by an elastic force so as to be displaced upward. The lid unit 60 is displaced upward with respect to the first ceiling panel 40 and the support 42 is displaced upward so as to follow the displacement of the lid unit 60. For this reason, it is hard to form a clearance gap between the cover unit 60 and the support body 42, and noise is hardly included in the sound information output from the cover unit 60.

  When the lid unit 60 repeats the vertical displacement with respect to the first ceiling panel 40, that is, when the lid unit 60 repeats the vertical vibration with respect to the first ceiling panel 40, the control device 70 is moved from the controller. Sound information corresponding to the received information is output. At this time, since the support body 42 follows the displacement of the lid unit 60 as described above, a gap is not easily formed between the lid unit 60 and the first ceiling panel 40. For this reason, noise such as chatter noise due to the contact between the lid unit 60 and the first ceiling panel 40 is unlikely to occur, and the sound quality of the sound information output into the bathroom 14 is unlikely to deteriorate. In addition, since the state in which the second elastic member 68 and the support 42 are in close contact with each other is easily maintained, the risk of moisture such as moisture in the bathroom 14 entering the back side of the first ceiling panel 40 is reduced. The

According to the first embodiment, the following effects can be further obtained.
(1) The support 42 is provided so as to surround the inspection port 43. According to this configuration, since the lid unit 60 is stably supported by the support 42, the followability of the support 42 accompanying the displacement of the lid unit 60 is enhanced. For this reason, a gap is not easily formed between the lid unit 60 and the support body 42, and noise such as chatter noise is unlikely to occur.

(2) The support body 42 is made of the same material as the panel body 41 and is formed integrally with the panel body 41. For this reason, the manufacturing cost of the 1st ceiling panel 40 is reduced.
(3) The support body 42 is configured to rise from the edge 43A of the inspection port 43 in the elastic portion 41B toward the lid unit 60, and supports the bottom surface 61C of the flange portion 61A. According to this configuration, since the bottom surface of the panel body 41 and the bottom surface of the lower lid 63 are close to each other in the vertical direction, the lid unit 60 hardly protrudes downward with respect to the first ceiling panel 40. For this reason, the beauty of the bathroom ceiling unit 20 is enhanced.

  (4) The first distance L1 that is the distance from the root of the support 42 to the inner peripheral surface 80B of the reinforcing member 80 is the second distance L2 that is the distance from the root of the flange portion 61A to the tip of the flange portion 61A. Longer than. According to this configuration, the elastic portion 41B is easily bent following the displacement of the lid unit 60, and it is difficult to form a gap between the lid unit 60 and the first ceiling panel 40, so noise such as chatter noise is generated. Hard to do.

  (5) In the planar direction of the lid unit 60, the support body 42 and the outer peripheral surface 63B of the lower lid 63 are opposed to each other with the first space S1 therebetween. According to this configuration, when the lid unit 60 vibrates, the support body 42 and the lower lid 63 do not easily interfere with each other. For this reason, noise due to contact between the support 42 and the lower lid 63 is less likely to occur.

  (6) In the planar direction of the lid unit 60, a second space is formed between the inner peripheral surface 80B that forms the through-hole 80A of the reinforcing member 80 and the outer peripheral surface 61B of the flange portion 61A that faces the inner peripheral surface 80B. S2 is provided. According to this configuration, when the lid unit 60 vibrates, the flange portion 61A and the reinforcing member 80 are unlikely to interfere with each other. For this reason, noise due to contact between the reinforcing member 80 and the flange portion 61A is less likely to occur.

  (7) The shape of the support 42 in the plan view of the first ceiling panel 40 is an ellipse. According to this structure, compared with the case where the shape of the support body 42 is a shape including a corner, when the lid unit 60 vibrates, a difference in deformation amount of each part of the support body 42 hardly occurs, and the lid unit 60 Is difficult to lift locally from the first ceiling panel 40. For this reason, noise such as chatter noise due to contact between the lid unit 60 and the first ceiling panel 40 is unlikely to occur.

  (8) The shape of the lid unit 60 is an ellipse. According to this configuration, since the portion where the distance from the vibrator 66 to the edge of the lid 61 changes rapidly in the planar direction of the lid unit 60 is not included, the sound wave output from the lid unit 60 is not easily distorted.

  (9) The vibrator 66 is provided at the center of the lid unit 60 in a plan view of the lid unit 60. According to this configuration, since the difference in the distance from the vibrator 66 to the edge of the lid 61 is small in the planar direction of the lid unit 60, the sound wave output from the lid unit 60 is not easily distorted.

  (10) The inspection port 43 is provided in the first ceiling panel 40 so that the center of the inspection port 43 does not coincide with the center of the ceiling 30 in a plan view of the first ceiling panel 40. That is, the position of the lid unit 60 on the ceiling 30 is shifted from the center of the ceiling 30. According to this configuration, the phase of the reflected wave output from the lid unit 60 and reflected by the side wall panel 12 and the floor panel 11 and the phase of the sound wave separately output from the lid unit 60 are unlikely to be in opposite phases. For this reason, the possibility that the sound pressure of the sound information viewed by the user is reduced is reduced.

  (11) The surface of the floor panel 11 is inclined with respect to the surface of the ceiling panels 40 and 50 on the bathroom 14 side. According to this configuration, the traveling direction of the sound wave output from the lid unit 60 and the traveling direction of the reflected wave reflected by the floor panel 11 are easily shifted, and the reflected wave and the sound wave output from the lid unit 60 interfere with each other. Hateful. For this reason, the sound pressure of the sound wave output from the lid unit 60 is unlikely to decrease.

  (12) The surface of the floor panel 11 is inclined so as to become lower from the side wall panel 12 away from the bathtub 13 toward the bathtub 13. According to this configuration, the reflected wave reflected by the floor panel 11 is likely to travel toward the bathtub 13, and a sound wave having a high sound pressure is likely to reach a user taking a bath in the bathtub 13.

  (13) The surface of the floor panel 11 is provided with irregularities 11B. According to this configuration, the traveling direction of the sound wave output from the lid unit 60 and the traveling direction of the reflected wave reflected by the floor panel 11 are easily shifted, and the reflected wave and the sound wave output from the lid unit 60 interfere with each other. Hateful. For this reason, the sound pressure of the sound wave output from the lid unit 60 is unlikely to decrease.

(Embodiment 2)
The bathroom ceiling unit 20 of the second embodiment is different from the bathroom ceiling unit 20 of the first embodiment in the points described below, and has substantially the same configuration as the bathroom ceiling unit 20 of the first embodiment in other points. . In the description of the bathroom ceiling unit 20 in the second embodiment, the same reference numerals are given to the components common to the bathroom ceiling unit 20 of the first embodiment, and a part or all of the description of the configuration is omitted.

  FIG. 8 is an exploded perspective view of the bathroom ceiling unit 20 according to the second embodiment. The bathroom ceiling unit 20 of the second embodiment includes a speaker 90 instead of the vibrator 66 (see FIG. 2) of the first embodiment. The speaker 90 includes a vibrator and a diaphragm (both not shown). The vibrator of the speaker 90 is provided on the lid 61 so that sound information is output to the bathroom 14 (see FIG. 1). Sound information is output from the lid unit 60 when the diaphragm of the speaker 90 vibrates due to the influence of vibration by the vibrator. That is, in the bathroom ceiling unit 20 of the first embodiment, a speaker is configured by the vibrator 66 and the lid 61, and in the second embodiment, a speaker 90 that vibrates its own diaphragm by its own vibrator is provided. The speaker 90 is disposed on the upper surface of the lower lid 63 in the accommodation space 64 of the lid 61. In one example, the speaker 90 is provided at the center of the lid unit 60 in a plan view of the lid unit 60. The speaker 90 is electrically connected to the control device 70.

  The control device 70 vibrates the vibrator of the speaker 90 based on a signal received from an external device such as a controller. When a force for displacing the lid unit 60 downward with respect to the first ceiling panel 40 is applied from the vibrator of the speaker 90 to the lid 61, the force is transmitted from the lid unit 60 to the support body 42. For this reason, the elastic part 41B bends so that the support body 42 is displaced downward with respect to the covering part 41A, and the lid unit 60 is displaced downward with respect to the first ceiling panel 40.

  On the other hand, after the elastic portion 41B is elastically deformed downward, when a force for displacing the lid unit 60 upward relative to the first ceiling panel 40 is applied from the vibrator of the speaker 90 to the lid 61, the elastic portion 41B Is bent by the elastic force so that the support 42 is displaced upward with respect to the covering portion 41A. The lid unit 60 is displaced upward with respect to the first ceiling panel 40 and the support 42 is displaced upward so as to follow the displacement of the lid unit 60. As described above, the lid unit 60 is displaced upward or downward, and the support body 42 follows the displacement of the lid unit 60, so that a gap is not easily formed between the lid unit 60 and the support body 42. The sound information that is output from is less likely to contain noise. According to the second embodiment, substantially the same effects as the effects (1) to (13) obtained by the first embodiment can be obtained.

(Embodiment 3)
The bathroom ceiling unit 120 of the third embodiment is different from the bathroom ceiling unit 20 of the first embodiment in the points described below, and has substantially the same configuration as the bathroom ceiling unit 20 of the first embodiment in other points. . In the description of the bathroom ceiling unit 120 in the third embodiment, the same reference numerals are given to the components common to the bathroom ceiling unit 20 of the first embodiment, and a part or all of the description of the configuration is omitted.

  As shown in FIG. 9, the bathroom ceiling unit 120 (see FIG. 11) includes a lid unit 160 instead of the lid unit 60 (see FIG. 4). Since the lid unit 160 has substantially the same configuration as the lid unit 60, the same reference numerals are given to the components common to the lid unit 60, and a part or all of the description of the configuration will be omitted.

  The bathroom ceiling unit 120 further includes a plurality of elastic supports 170. The elastic support 170 is an elastically deformable member. The elastic support 170 is made of the same material as the second elastic member 68 (see FIG. 11), for example. An example of the material of the elastic support 170 is rubber. The elastic support 170 is provided between the bottom surface 160A of the lid unit 160 and the elastic portion 41B (see FIG. 11). In one example, the elastic support 170 is attached to the bottom surface of the flange portion 61A and supported by the elastic portion 41B. An example of the shape of the elastic support 170 is a rectangular parallelepiped. An example of the number of elastic supports 170 is six. In the example shown in FIG. 9, the plurality of elastic supports 170 are arranged at predetermined intervals in the circumferential direction of the lid unit 160. In FIG. 9, the second elastic member 68 is omitted.

  The lid unit 160 further includes a protrusion 161. The function of the protrusion 161 is to hold the position of the lid unit 160 in the vertical direction with respect to the first ceiling panel 40 (see FIG. 11). The protruding portion 161 protrudes from the bottom surface 61C of the flange portion 61A of the lid 61 toward the elastic portion 41B. An example of the material of the protrusion 161 is ABS resin.

  The protrusion 161 includes a pair of peripheral walls 162 and a plurality of support portions 163 (see FIG. 10). The peripheral wall 162 is provided along the outer peripheral surface 61B of the flange portion 61A so as to cover the periphery of the lid 61. An example of the shape of the peripheral wall 162 is an arc shape in the plan view of the lid unit 160. A third space S3 is provided between one peripheral wall 162 and the other peripheral wall 162. The peripheral wall 162 protrudes from the tip of the flange portion 61A toward the elastic portion 41B so as to be continuous with, for example, the outer peripheral surface 61B of the flange portion 61A.

  As shown in FIG. 10, the plurality of support portions 163 are attached to the bottom surface 162 </ b> A of the peripheral wall 162, for example. The shape of the support portion 163 is, for example, a tapered shape that narrows from the contact surface with the peripheral wall 162 toward the bottom surface 163A. The area of the bottom surface 163A of the support portion 163 is smaller than the area of the bottom surface 170A of the elastic support 170, and smaller than the area of the contact surface with the peripheral wall 162 in the support portion 163. The shape of the bottom surface 163A of the support portion 163 is, for example, a rounded shape. An example of the number of the plurality of support portions 163 is six. Each support portion 163 is provided at a position near the elastic support 170 in the peripheral wall 162 (see FIG. 9). The plurality of support portions 163 are arranged at predetermined intervals in the circumferential direction of the lid unit 160. When the support part 163 is made of a material different from that of the peripheral wall 162, the support part 163 is softer than the peripheral wall 162 and harder than the second elastic member 68 (see FIG. 11). Is preferred.

  FIG. 11 shows a cross-sectional structure of the state before the lid unit 160 closes the inspection port 43. The elastic support body 170 is provided on the bottom surface 61C of the flange portion 61A so as to be disposed on the base side of the flange portion 61A with respect to the protruding portion 161. The elastic support 170 forms a state of projecting downward from the projecting portion 161 in a state where the elastic support 170 is not elastically deformed. The position of the bottom surface 170A of the elastic support 170 is lower than the bottom surface 163A of the support portion 163 in the vertical direction.

  FIG. 12 shows a cross-sectional structure in a state where the lid unit 160 closes the inspection port 43. The elastic support 170 is elastically deformed so as to contract by contact with the elastic portion 41B. The support portion 163 is supported by the elastic portion 41B in a state where the elastic support 170 is elastically deformed. Since the support portion 163 is supported by the elastic portion 41B, the vertical position of the lid unit 160 with respect to the first ceiling panel 40 is maintained. The lid unit 160 is supported by the elastic portion 41B so that it can be displaced in the vertical direction with respect to the first ceiling panel 40 in accordance with the bending deformation of the elastic portion 41B and the elastic deformation of the elastic support 170.

  The second elastic member 68 is elastically deformed so as to contract by contact with the support 42. When the second elastic member 68 is supported by the support 42, the second elastic member 68 and the support 42 are brought into close contact with each other, and moisture such as moisture in the bathroom 14 (see FIG. 1) is in contact with the first ceiling panel. Intrusion into the back side of 40 is prevented.

The operation of the bathroom ceiling unit 120 will be described with reference to FIGS. 13 and 14.
The controller of the bathroom ceiling unit 120 outputs a signal in response to a user operation. In one example, the signal includes information about sound. The control device 70 (see FIG. 2) vibrates the vibrator 66 (see FIG. 2) based on the signal received from the controller.

  FIG. 13 shows a state in which the lid unit 160 is displaced downward with respect to the first ceiling panel 40. When a force that causes the lid unit 160 to be displaced downward relative to the first ceiling panel 40 is applied from the vibrator 66 to the lid 61, the force is mainly transmitted from the protruding portion 161 to the elastic portion 41B. For this reason, the elastic part 41B is bent so that the support 42 is displaced downward with respect to the covering part 41A, and the elastic support 170 is elastically deformed so as to extend following the displacement of the elastic part 41B. The elastic member 68 is elastically deformed so as to extend following the displacement of the support 42. Thus, the lid unit 160 is displaced downward while bending the elastic portion 41B, whereby the elastic support body 170 follows the displacement of the elastic portion 41B, and the second elastic member 68 follows the displacement of the support body 42. Therefore, a gap is not easily formed between the lid unit 160 and the first ceiling panel 40, and noise is not easily included in the sound information output from the lid unit 160.

  FIG. 14 shows a state in which the lid unit 160 is displaced upward with respect to the first ceiling panel 40. After the elastic portion 41B is elastically deformed downward, when a force for displacing the lid unit 160 upward with respect to the first ceiling panel 40 is applied from the vibrator 66 to the lid 61, the elastic portion 41B is covered with the covering portion 41A. In contrast, the support 42 is bent by an elastic force so as to be displaced upward. The lid unit 160 is displaced upward with respect to the first ceiling panel 40, the elastic portion 41B bends following the displacement of the elastic support 170, and the elastic support 170 is contracted by the force received from the elastic portion 41B. It is elastically deformed. Further, the support body 42 is displaced upward following the displacement of the second elastic member 68, and the second elastic member 68 is elastically deformed so as to be contracted by the force received from the support body 42. For this reason, it is difficult for a gap to be formed between the lid unit 160 and the first ceiling panel 40, and noise is hardly included in the sound information output from the lid unit 160.

  When the lid unit 160 repeats the vertical displacement with respect to the first ceiling panel 40, sound information corresponding to the information received from the controller by the control device 70 is output. At that time, as described above, since a gap is not easily formed between the lid unit 160 and the first ceiling panel 40, noise such as chatter noise due to contact between the lid unit 160 and the first ceiling panel 40 is less likely to occur. The sound quality of the sound information output in the bathroom 14 is unlikely to deteriorate. In addition, since the state in which the second elastic member 68 and the support 42 are in close contact with each other is easily maintained, the risk of moisture such as moisture in the bathroom 14 entering the back side of the first ceiling panel 40 is reduced. The

According to the third embodiment, the following effects can be further obtained.
(14) The elastic support 170 is provided between the bottom surface 160A of the lid unit 160 and the elastic portion 41B. According to this configuration, the vibration of the lid unit 160 is absorbed by the elastic support 170. For this reason, a gap is not easily formed between the lid unit 160 and the first ceiling panel 40, and the sound quality of the sound information output into the bathroom 14 is unlikely to deteriorate.

  (15) The protruding portion 161 protrudes from the bottom surface 61C of the flange portion 61A toward the elastic portion 41B, and is supported by the elastic portion 41B in a state where the elastic support 170 is elastically deformed. According to this configuration, the vertical position of the lid unit 160 with respect to the first ceiling panel 40 is held by the projecting portion 161, and the lid unit 160 is relative to the first ceiling panel 40 due to the elastic deformation of the elastic support 170. It is hard to sink. For this reason, the beauty of the bathroom ceiling unit 120 is enhanced.

  (16) The support portion 163 of the protrusion 161 is supported by the elastic portion 41B in a state where the elastic support 170 is elastically deformed. According to this configuration, the contact area with the elastic portion 41B is smaller than when the bottom surface 162A of the peripheral wall 162 is supported by the elastic portion 41B. For this reason, even if it is a case where the protrusion part 161 and the elastic part 41B leave | separate in the process in which the cover unit 160 vibrates with respect to the 1st ceiling panel 40, it influences the sound quality of the sound information output in the bathroom 14. It is hard to come out.

  (17) The elastic support body 170 is provided on the bottom surface 61C of the flange portion 61A so as to be disposed closer to the root side of the flange portion 61A than the protruding portion 161. According to this structure, the elastic support body 170 is supported by the part close | similar to the support body 42 among the elastic parts 41B. A portion of the elastic portion 41 </ b> B close to the support 42 has a large amount of deformation due to the vibration of the lid unit 160. For this reason, the vibration of the lid unit 160 is easily absorbed by the elastic support 170. According to the third embodiment, substantially the same effects as the effects (1) to (13) obtained by the first embodiment can be obtained.
