  2. Description of the Related Art Conventionally, as disclosed in Patent Document 1, a structure in which an actuator is attached to a kitchen sink or the like to produce an acoustic effect is known. According to such a structure, the sink that vibrates by the actuator becomes a sounding body, and can reproduce sound.

JP 2002-209287 A

However, in the structure of Patent Document 1, when a medium or low tone is reproduced, the amplitude of vibration in the sink increases. For this reason, there is an inconvenience that the user who touches the sink feels uncomfortable during middle or low-pitched sound reproduction, or the tableware or the like vibrates on the sink, which impairs the handling and workability of the sink. .
Further, since the sink is vibrated as a whole, the electric power required to reproduce medium and bass sounds having a large amplitude increases. For this reason, as the mass of the sink or the like to be vibrated increases, an amplifier with a higher output is required, which not only increases the cost burden of the equipment, but also causes the inconvenience that the sound quality to be reproduced decreases.

[Object of invention]
The present invention has been proposed in view of such disadvantages, the object, while keeping the amplitude of the vibration of the top wall portion in a small state, it is possible to hear the good reproduced sound by the vibration It is to provide a work table.

In order to achieve the above object, the work table of the present invention is attached to a peripheral wall portion arranged on a predetermined installation surface, a top wall portion provided on an upper portion of the peripheral wall portion, and a back surface of the top wall portion. Actuator and
The actuator is provided so that only the high sound can be reproduced by vibrating the top wall ,
In the space surrounded by the peripheral wall portion and the top wall portion, a speaker device capable of reproducing medium and low sounds is provided, and the speaker device is disposed below the actuator,
A plurality of passages are provided in the peripheral wall portion, and a configuration is adopted in which the passages allow the reproduced sound from the speaker device to pass through substantially radially in a plan view .

  Furthermore, it is preferable that a duct is provided on the inner side of the peripheral wall portion, and a reproduction sound from the speaker device is passed through the duct.

  Further, the speaker device may be arranged forward or rearward, and the reproduced sound may flow in the front-rear direction via the sound pressure adjusting means.

  A reinforcing member that suppresses resonance due to the reproduced sound can be provided in the plane of the peripheral wall portion.

According to the present invention, when only the high sound is reproduced by vibrating the top wall portion of the work table , the amplitude of vibration can be made relatively small. Accordingly, it is possible to prevent the person who touched the top wall from feeling uncomfortable, and it is possible to use an amplifier with a small output that is advantageous in terms of cost by suppressing power consumption required for vibration. Furthermore, it is possible to prevent the object placed on the top wall portion from vibrating and rattling, and it is possible to avoid the loss of workability as in the conventional sink. Moreover, since the high sound is reproduced from the top wall portion closer to the user's ear, the sound image can be localized near the ear, and the reproduced sound can be easily heard. Here, since the high sound is a band in which human hearing is most sensitive, the ease of hearing of the reproduced sound is well maintained.

Furthermore , since the speaker device is arranged in a space surrounded by the peripheral wall portion and the top wall portion, the speaker device can be easily and quickly installed on a workbench production line or the like, and the work on the construction site or the like can be reduced. It becomes possible. Further, since the sound range is divided and reproduced by the top wall portion and the speaker device, the quality of these reproduced sounds can be kept better.

  Further, since the passage of the peripheral wall portion allows the reproduced sound from the speaker device to pass through in a substantially radial manner, the sound quality around the peripheral wall portion can be made uniform. Therefore, a comfortable omnidirectional sound field is created so as to surround the work table, and when the work table is surrounded by a plurality of users, it is possible to give a similar acoustic effect to each user.

  Furthermore, when the reproduced sound from the speaker device is flowed through the duct, it is possible to suppress a decrease in the sound pressure of the reproduced sound depending on the distance from the speaker device, thereby improving the degree of freedom of the layout of the speaker device in the peripheral wall portion. be able to. In addition, by adjusting the length and opening area of the duct, it is possible to control the frequency of the sound that flows outside.

  In addition, when the reproduced sound is played back and forth through the sound pressure adjusting means, the sound pressure at the front and rear is adjusted to be substantially the same even if the speaker device is moved forward or backward in the peripheral wall portion. Can do. Thereby, when the space in the peripheral wall portion is used as a storage space, the speaker device is less likely to get in the way and the storage space can be easily used.

Furthermore , by providing a reinforcing member in the surface of the peripheral wall portion, it is possible to suppress resonance of the intermediate wall portion and the peripheral wall portion due to reproduced sound from the speaker device, and to prevent generation of unpleasant sound.

In the present specification and claims, the “workbench” means a concept including a kitchen, a storage cabinet, a table, a work table, a washstand, and the like.
Further, terms indicating the position or direction such as “front”, “rear”, “upper”, “lower”, “left”, “right”, etc., when viewed in the direction of arrow A in FIG. 1 unless otherwise specified. Based on

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

[First Embodiment]
FIG. 1 is a schematic perspective view of the kitchen according to the first embodiment. In this figure, a kitchen 10 as a work table is arranged in a central part of a kitchen room or a boundary part between a kitchen room and a dining room in a general house or the like. The kitchen 10 is disposed on the installation surface F, and has a cabinet body 11 having a storage space S1 therein, an upper portion of the cabinet body 11, and a faucet device (not shown) and a sink 13. And a counter 14 as a top wall portion formed in a substantially rectangular shape that is horizontally long in a plan view.

  The cabinet body 11 includes three cabinets arranged in the left-right direction, that is, first to third cabinets 16 to 18 positioned from left to right.

  2 and 3, the first cabinet 16 includes a pair of left and right side plates 20, 21 and a pair of doors 22, 22 provided on the front and rear sides of the side plates 20, 21, respectively. A front plate 24 that connects the front portions of the side plates 20 and 21 on the upper side of the doors 22 and 22 and a rear plate 25 that connects the rear portions, and a lower portion of the front plate 24 and the rear plate 25 are connected. A partition plate 26 as an intermediate wall portion positioned substantially parallel to the installation surface F, and a bottom plate 27 as an intermediate wall portion connected between the lower portions of the side walls 20 and 21 and positioned substantially parallel to the installation surface F; It is arranged on the installation surface F, and is configured to include a kick-in portion 29 that forms a substantially square frame shape (see FIG. 4) in plan view. The storage space S <b> 1 in the first cabinet 16 is surrounded by the counter 14, the side plates 20 and 21, the door 22, the front plate 24 and the rear plate 25 and is substantially concealed from the user of the counter 14. An upper passage 30 having a horizontally long concave shape is provided at each of upper ends of the left side plate 20, the front plate 24, and the rear plate 25, and from the outside of the first cabinet 16 and the partition plate 26 through the upper passage 30. The upper storage space S1 communicates with the upper storage space S1. In addition, a plurality of substantially circular lower passages 31 are provided on both front and rear surfaces and the left surface of the kicking portion 29, and the lower passage 31 surrounds the kicking portion 29, the bottom plate 27, and the installation surface F. S2 communicates with the outside of the kick-in portion 29. Here, in the storage space S1, there are provided first and second speakers 33, 34 constituting a speaker device and having different reproduction sound ranges.

  The first speaker 33 is constituted by a tweeter or a squawker that is smaller than the second speaker 34 and can reproduce medium sounds. The first speaker 33 is attached to an in-plane central portion on the lower surface of the partition plate 26, and reproduces medium sound toward the lower surface of the counter 14 through an opening 26 </ b> A formed in the partition plate 26.

  The second speaker 34 is attached to the upper surface side in the in-plane central portion of the bottom plate 27, whereby the first speaker 33 is positioned above the second speaker 34. The second speaker 34 is provided so as to be able to reproduce low sounds, and reproduces toward the lower installation surface F through the opening 27 </ b> A of the bottom 27.

The second cabinet 17 is substantially the same as the first cabinet 16 in that the installation of the speakers 33 and 34 is omitted and the upper passage 30 and the lower passage 31 are not formed. Further, the third cabinet 18 employs a structure that is symmetrical with respect to the first cabinet 16. Therefore, in the 2nd and 3rd cabinets 17 and 18, the same code | symbol is used about the same or equivalent component as the 1st cabinet 16, and description is abbreviate | omitted.
Here, a peripheral wall part is comprised by the side wall 20 exposed outside the 1st thru | or 3rd cabinets 16-18, the door 22, the front board 24, the rear board 25, and the kicking part 29. FIG.

  In the present embodiment, the height of the counter 14 is set so as to be located near the waist of a standing user, and the upper surface of the counter 14 can be used as a work surface or a work area. Here, on the lower surface (back surface) of the counter 14 and above the first speakers 33, 33, actuators 35, 35 are respectively attached. Each actuator 35, 35 is provided so that the counter 14 is vibrated so as to act as a vibrating body, and only the high sound can be reproduced by the vibration.

  Here, the first and second speakers 33 and 34 and the actuator 35 are connected to an acoustic device including various tuners, players, amplifiers, and the like via a connection cord (not shown). The acoustic device may be stored in the storage space S1 or installed in a place different from the kitchen 10, for example, a dining room or a living room. In addition, the operation of the acoustic device can be exemplified by an operation panel connected to the acoustic device and attached to a predetermined wall surface, a wireless remote controller, or the like.

In the above configuration, when output is performed from the acoustic device to the first and second speakers 33 and 34 and the actuator 35, low sound, medium sound and high sound are reproduced simultaneously.
Specifically, the actuator 35 vibrates the counter 14 to reproduce a high tone, and the high tone is radiated upward from the entire counter 14. The medium sound reproduced from the first speaker 33 is reflected on the lower surface of the counter 14 and the upper surface of the partition plate 26 and flows to the outside of the cabinet body 11 through each upper passage 30 as an indirect sound. The bass reproduced from the second speaker 34 is reflected on the installation surface F and the bottom surface of the bottom plate 27 and flows as an indirect sound from the space S2 to the outside of the kick-in portion 29 through the lower passages 31.

  Here, as shown in FIGS. 2 and 4, the upper passage 30 and the lower passage 31 are formed on both sides of the cabinet body 11 in the front-rear direction (vertical direction in the drawing) and on both sides in the left-right direction. The reproduced sound from the speakers 33 and 34 passes through the upper passage 30 and the lower passage 31 and flows outwardly from the cabinet body 11 in a plan view substantially radially (in the direction of the broken arrow in FIGS. 2 and 4). Become.

  Therefore, according to the first embodiment, since the sound reproduced from the counter 14 is only a high tone, it is possible to suppress the vibration amplitude of the counter 14 from increasing. As a result, it is possible to avoid that the user who performs cooking or the like at the counter 14 feels uncomfortable, and even if tableware or cooking utensils on the counter 14 are placed, they are prevented from rattling and workability is improved. It can be maintained well. Further, compared to the case where the entire audible sound range is reproduced by the counter 14, not only the sound quality can be improved, but also the power consumption can be reduced. In addition, since the high sound is a band in which human hearing is sensitive, it is possible to obtain a sufficient acoustic effect with a small amount of power, and it is also possible to reduce power consumption.

  In addition, since the high sound is reproduced from the counter 14, it is possible to stably localize the sound image at a position closer to the user's ear. Moreover, while the medium sound passes through the upper passage 30 in a substantially radial manner, the low sound passes through the lower passage 31 through the space S2 in the kick-in portion 29. The pressure can be increased. As a result, an omnidirectional sound field is created around the kitchen 10. For example, when a plurality of users enclose the kitchen 10 and perform cooking work, the sound effect is uniform regardless of the position of each user. This makes it possible to create a good atmosphere.

  Moreover, since each speaker 33 and 34 is arrange | positioned in storage space S1 and is substantially concealed, it can avoid that each speaker 33 and 34 gets dirty by the oil etc. at the time of cooking operation. Furthermore, since the reproduced sound from the speakers 33 and 34 is caused to flow substantially radially through the partition plate 26 and the installation surface F, the number of speakers 33 and 34 can be reduced, and wiring work and the like can be simplified. It becomes possible.
