[First embodiment]
[composition]

First, referring to Figures 7 and 8, a smartphone 100 will be described as an example of a mobile terminal. However, the smartphone 100 is an object to be supported by the mobile terminal stand 1, and is not a component of the mobile terminal stand 1.

7 and 8, the smartphone 100 has sound emitting units 101L and 101R at one end (left end 100L) and the other end (right end 100R) in the longitudinal direction. As shown in the figure, the sound emitting units 101L and 101R are located at both the left and right ends (left end 100L and right end 100R) of the smartphone 100 when the smartphone 100 is placed horizontally. In this example, the left sound emitting unit 101L is provided in the vertical center of the front surface 100f of the smartphone 100 placed horizontally. The right sound emitting unit 101R is provided in the upper half of the right end surface of the smartphone 100 placed horizontally.

Most of the front surface 100f of the smartphone 100 is a touch display, except for at least a portion of the periphery. A camera 102 and a brightness sensor 103 are provided near the left sound output section 101L. A fingerprint sensor 104 is provided on the front surface 100f of the right end 100R of the smartphone 100. The fingerprint sensor 104 is provided in the vertical center of the smartphone 100 when placed horizontally.

As shown in Figures 1 to 6, the mobile terminal stand 1 of the first embodiment has a mobile terminal support part 10 and a sound reflecting part 20.

As shown in Figures 7 and 8, the mobile terminal support unit 10 is a component that can support a smartphone 100, as an example of a mobile terminal, in a horizontal position with the entire front surface 100f exposed.

In one embodiment, "exposing the entire front surface 100f of the smartphone 100" means "so that the entire front surface 100f of the smartphone 100 can be seen and touched." Therefore, something that has a portion into which the end of the smartphone 100 fits (for example, the holding portion 3 in Patent Document 1) is not a mobile terminal support portion 10. This is because if there is a portion into which the end of the smartphone 100 fits, part of the front surface 100f of the smartphone 100 becomes invisible and cannot be touched.

In one embodiment, "supporting the smartphone 100 in a horizontal position" means "supporting the smartphone 100 in a position in which both ends in the longitudinal direction are positioned on the left and right." That is, in one embodiment, it is assumed that the contour shape of at least one side of the smartphone 100 is close to a rectangle. "Close to a rectangle" includes an approximate rectangle with rounded corners, an approximate rectangle with some curved sides, an approximate rectangle with some curved sides, etc.

The sound reflection unit 20 is a component that has the function of reflecting forward the sound emitted from the sound emission units 101L, 101R located at both the left and right ends (left end 100L, right end 100R) of the smartphone 100 supported horizontally on the mobile terminal support unit 10. "Reflecting forward the sound emitted from the sound emission units 101L, 101R" means "reflecting forward at least a part of the sound emitted from the sound emission units 101L, 101R". It is not realistic to reflect forward all of the sound emitted from the sound emission units 101L, 101R. "Reflecting forward the sound emitted from the sound emission units 101L, 101R" may be read as "suppressing backward diffusion of the sound emitted from the sound emission units 101L, 101R".

As shown in FIG. 10, the sound reflecting section 20 has a first portion 21 and a second portion 22. The first portion 21 is a portion that overlaps with the rear side of the left end portion 100L of the smartphone 100 supported horizontally on the mobile terminal support section 10. The second portion 22 is a portion that overlaps with the rear side of the right end portion 100R of the smartphone 100 supported on the mobile terminal support section 10.

The sound reflection section 20 has a third part 23 and a fourth part 24. The third part 23 is a part that extends to the left from the first part 21. The fourth part 24 is a part that extends to the right from the second part 22.

The third part 23 includes a fifth part 25. The fifth part 25 is a part located on an extension to the left of the smartphone 100 supported horizontally on the mobile terminal support part 10. The fourth part 24 includes a sixth part 26. The sixth part 26 is a part located on an extension to the right of the smartphone 100 supported horizontally on the mobile terminal support part 10. A space SL exists between the left end 100Ll of the smartphone 100 and the fifth part 25. A space SR exists between the right end 100Rr of the smartphone 100 and the sixth part 26.

The first portion 21, the third portion 23, and the fifth portion 25 are inclined to the left as they move forward. The second portion 22, the fourth portion 24, and the sixth portion 26 are inclined to the right as they move forward. In this example, the sound reflecting portion 20 has left and right bent portions 31, 32 that are bent forward. In this example, the fifth portion 25 includes a portion of the left bent portion 31. The sixth portion 26 includes a portion of the right bent portion 32.

The third portion 23 extends further forward and to the left from the fifth portion 25. The fourth portion 24 extends further forward and to the right from the sixth portion 26.

The sound reflecting section 20 has a seventh portion 27 extending leftward from the left end 10L of the mobile device support section 10, and an eighth portion 28 extending leftward from the right end 10R of the mobile device support section 10. A space exists between the seventh portion 27 and the rear surface of the left end 100L of the smartphone 100 supported horizontally on the mobile device support section 10. A space exists between the eighth portion 28 and the rear surface of the right end 100R of the smartphone 100 supported horizontally on the mobile device support section 10. In other words, the left and right ends of the smartphone 100 supported horizontally on the mobile device support section 10 are not in contact with the sound reflecting section 20.

As shown in Figures 5, 6 and 9, the mobile device support part 10 has a base part 11, a support part 12 and a backrest part 13.

The base 11 has a lower surface 11a that contacts the surface on which the mobile terminal stand 1 is placed (hereinafter referred to as the "installation surface"). The lower surface 11a is provided with a non-slip surface (not shown) that generates friction between the lower surface 11a and the installation surface.

The support portion 12 is a portion that supports the smartphone 100 from below. The upper surface 12a of the support portion 12 extends diagonally upward toward the front. In this example, the support portion 12 itself extends diagonally upward toward the front from the front end portion 11b of the base portion 11. The upper surface 12a of the support portion 12 is the portion that contacts the lower end 100a of the smartphone 100 when placed horizontally. The upper surface 12a of the support portion 12 is also the portion that contacts the lower end 100a of the smartphone 100 when placed vertically (see FIG. 11). In this configuration, the contact between the smartphone 100 and the support portion 12 is line contact or surface contact.

The backrest 13 is a portion that supports the smartphone 100 from behind. The front surface 13a of the backrest 13 is tilted backward. That is, the front surface 13a of the backrest 13 extends diagonally upward toward the rear. In this example, the backrest 13 itself extends diagonally upward toward the rear from the front end portion 11b of the base 11. The backward tilt angle θ of the front surface 13a of the backrest 13 is, for example, 25° to 35°. The backward tilt angle θ is the angle between the vertical axis z and the front surface 13a of the backrest 13 when the mobile terminal stand 1 is installed on a horizontal installation surface S. The front surface 13a of the backrest 13 is a portion that contacts the back surface 100c of the smartphone 100 placed horizontally. The front surface 13a of the backrest 13 is also a portion that contacts the back surface 100c of the smartphone 100 placed vertically (see FIG. 11). In this configuration, the contact between the smartphone 100 and the backrest 13 is surface contact.

The backrest portion 13 is integrated with the sound reflecting portion 20. In this example, the sound reflecting portion 20 is fixed to the back surface of the backrest portion 13. The seventh portion 27 of the sound reflecting portion 20 extends from the left end of the back surface of the backrest portion 13 to the first portion 21. The eighth portion 28 of the sound reflecting portion 20 extends from the right end of the back surface of the backrest portion 13 to the second portion 22.

[Action and Effects]
The mobile terminal stand 1 configured as described above supports the smartphone 100 by the mobile terminal support part 10. The mobile terminal support part 10 can support the smartphone 100 in either a horizontal or vertical orientation. The only task imposed on the user in order to support the smartphone 100 on the mobile terminal support part 10 is to bring the lower end of the smartphone 100 into contact with the support part 12, bring the back surface 100c of the smartphone 100 into contact with the backrest part 13, and lean the smartphone 100 against the mobile terminal support part 10.

This mobile device stand 1 allows the user to support the smartphone 100 on the mobile device support part 10 with only the extremely simple task of leaning the smartphone 100 against the mobile device support part 10. With the smartphone 100 leaned against the mobile device support part 10, the user can listen to the sounds emitted from both sound emitting parts 101L and 101R while viewing the images displayed on the touch display that constitutes most of the area of the front surface 100f of the smartphone 100.

The mobile device stand 1 supports the smartphone 100 by tilting it backwards using the mobile device support part 10. In this example, the smartphone 100 is supported in a position tilted, for example, 25° to 35° from the vertical position. The smartphone 100 is supported in a stable state with its weight entrusted to the support part 12 and the backrest part 13.

The mobile terminal stand 1 can support the smartphone 100 by exposing the entire front surface 100f with the mobile terminal support part 10. Since the entire front surface 100f of the smartphone 100 supported by the mobile terminal support part 10 is exposed, the user can see and touch the entire front surface 100f of the smartphone 100. Therefore, the user can touch the front surface 100f of the smartphone 100 while the smartphone 100 is supported by the mobile terminal support part 10 to operate the smartphone 100. This operation includes an operation performed by touching a finger or a stylus pen to the touch display that constitutes most of the area of the front surface 100f of the smartphone 100, and an operation performed by touching a finger to the fingerprint sensor 104. In addition, the camera 102 can be used while the smartphone 100 is supported by the mobile terminal support part 10. Since the brightness sensor 103 is exposed, the exposure adjustment of the camera 102 based on the illuminance of the front surface 100f of the smartphone 100 or the brightness adjustment of the touch display can be performed as usual. "Normally" means the same as when the smartphone 100 is not supported by the mobile terminal support part 10 and the brightness sensor 103 is not blocked by an obstacle such as a finger.

The entire front surface 100f of the smartphone 100 supported by the mobile terminal support part 10 is exposed, and a space Sl exists between the left end 100Ll of the smartphone 100 and the fifth part 25, so that the fifth part 25 does not become an obstacle when the user touches the front surface of the left end part 100L of the smartphone 100 with his/her finger. Also, the entire front surface 100f of the smartphone 100 supported by the mobile terminal support part 10 is exposed, and a space Sr exists between the right end 100Rr of the smartphone 100 and the sixth part 26, so that the sixth part 26 does not become an obstacle when the user touches the front surface of the right end part 100R of the smartphone 100 with his/her finger.

The mobile device stand 1 has sound reflecting sections 20 located behind and on both the left and right sides of the smartphone 100 supported horizontally on the mobile device support section 10, and is therefore able to reflect forward the sound emitted from the sound emitting sections 101L, 101R located at both the left and right ends (left end 100L, right end 100R). This prevents the sound emitted from the smartphone 100 from diffusing backward, and efficiently guides the sound forward, i.e., to the user.

In detail, because the sound reflection unit 20 has the first portion 21, it is possible to suppress the backward diffusion of the sound emitted from the sound emission unit 101L on the left side of the smartphone 100, and to efficiently guide the sound to the user side. In addition, because the sound reflection unit 20 has the second portion 22, it is possible to suppress the backward diffusion of the sound emitted from the sound emission unit 101R on the right side of the smartphone 100, and to efficiently guide the sound to the user side.

More specifically, because the sound reflection unit 20 has the third portion 23, it is possible to more effectively suppress the backward diffusion of sound emitted from the sound emission unit 101L on the left side of the smartphone 100, and to more efficiently guide the sound to the user side. In addition, because the sound reflection unit 20 has the fourth portion 24, it is possible to more effectively suppress the backward diffusion of sound emitted from the sound emission unit 101R on the right side of the smartphone 100, and to more efficiently guide the sound to the user side.

By including the fifth portion 25 in the third portion 23, the sound emitted from the sound emission section 101L on the left side of the smartphone 100 can be prevented from diffusing backward and to the left, and the sound can be efficiently guided to the user side. In addition, by including the sixth portion 26 in the fourth portion 24, the sound emitted from the sound emission section 101R on the right side of the smartphone 100 can be prevented from diffusing backward and to the right, and the sound can be efficiently guided to the user side.

When the mobile terminal stand 1 is viewed from the front or front, the fifth portion 25 is inclined to the left as it faces forward, so that the sound emitted from the left sound emission section 101L of the smartphone 100 can be guided to the user while suppressing the reflection to the right of the sound emitted to the right. Also, the sixth portion 26 is inclined to the right as it faces forward, so that the sound emitted from the right sound emission section 101R of the smartphone 100 can be guided to the user while suppressing the reflection to the left of the sound. This makes it possible to guide the left and right sounds emitted from the smartphone 100 to the user while suppressing crosstalk between the left and right sounds emitted from the smartphone 100.

The third part 23 extends further forward from the fifth part 25 to the left, and the fourth part 24 extends further forward from the sixth part 26 to the right, so that the left and right sounds emitted from the smartphone 100 can be more efficiently guided to the user while suppressing crosstalk between the left and right sounds emitted from the smartphone 100.

Therefore, according to the mobile terminal stand 1, the acoustic characteristics of the smartphone 100 can be effectively utilized to deliver left and right sounds emitted from the smartphone 100 to the user. The user can listen to left and right sounds that effectively utilize the acoustic characteristics of the smartphone 100 while viewing the entire image displayed on the touch display that occupies most of the front surface 100f of the smartphone 100. For example, when content consisting of a video and stereo sound is played on the smartphone 100, the user can enjoy stereo sound with excellent three-dimensional effect by viewing the entire image displayed on the touch display that occupies most of the front surface 100f of the smartphone 100 and listening to left and right sounds that effectively utilize the acoustic characteristics of the smartphone 100.

Since there is a space between the back of the left end 100L of the smartphone 100 supported horizontally on the mobile terminal support part 10 and the seventh part 27 of the sound reflection part 20, it is possible to prevent chattering noises caused by direct contact between the left end 100L of the smartphone 100 and the sound reflection part 20 when the smartphone 100 outputs sound. Since there is a space between the back of the right end 100R of the smartphone 100 supported horizontally on the mobile terminal support part 10 and the eighth part 28 of the sound reflection part 20, it is possible to prevent chattering noises caused by direct contact between the right end 100R of the smartphone 100 and the sound reflection part 20 when the smartphone 100 outputs sound. This configuration is optimal for use with some models of smartphones 100 that have a vibration function that works in conjunction with sound output. In addition, since the space on the seventh portion 27 side and the space on the eighth portion 28 side are partitioned left and right by the backrest 13, the sound transmitted rearward from the left end 100L and the right end 100R of the smartphone 100 is guided upward and downward. This can be expected to produce an acoustic effect.

The smartphone 100 in the second embodiment can execute various functions such as transmission and reception, audio output, and image display while charging. The other configurations of the smartphone 100 in the second embodiment are the same as those of the smartphone 100 in the first embodiment.

The sound reflection section 20 of the mobile terminal stand 2 of the second embodiment is also an embodiment of a sound reflection device. That is, the mobile terminal stand 2 of the second embodiment can be realized by using a ready-made wireless charger that has a backrest section that supports the smartphone 100 from behind and that contactlessly supplies power to the smartphone 100 supported on the backrest section as the mobile terminal support section 10, and attaching the sound reflection section 20 as a sound reflection device to the rear surface of the backrest section 13 of the mobile terminal support section 10. The connection between the backrest section 13 and the sound reflection section 20 can be realized by various methods such as adhesion, fastening, engagement, and magnetic attraction.

[Action and Effects]
According to the mobile terminal stand 2 configured as described above, the user can support the smartphone 100 on the mobile terminal support part 10 and charge the smartphone 100 by simply leaning the smartphone 100 against the mobile terminal support part 10. The user can view images displayed on the touch display that constitutes most of the area of the front surface 100f of the smartphone 100 and sounds emitted from both sound emission parts 101L and 101R while charging the smartphone 100. Since content can be played while charging the smartphone 100, playback interruption due to insufficient charging does not occur. The user can enjoy streaming content distributed by Amazon (registered trademark) Prime Video, Hulu (registered trademark), NETFLIX (registered trademark), YouTube (registered trademark), etc. without worrying about interruption due to insufficient charging.

The other functions and effects of the mobile terminal stand 2 of the second embodiment are the same as those of the mobile terminal stand 1 of the first embodiment.

15 to 20 and 31, the mobile terminal stand 3 of the third embodiment is configured to include a plate member 40 and a leg member 50. The plate member 40 has a horizontally long rectangular shape.

The plate member 40 is made of wood, metal, or wood. The plate member 40 has a pair of left and right through holes 41 and a notch 42. The pair of left and right through holes 41 are provided symmetrically between the vertical center and the lower end 40a of the plate member 40. The notch 42 is provided in the horizontal center of the lower end of the plate member 40.

The leg member 50 is a hard metal member. The leg member 50 is manufactured by bending a metal bar having a circular cross-sectional shape. An example of the metal bar is a bar made of stainless steel. The leg member 50 has a pair of left and right smartphone support parts 51, a pair of left and right charger support parts 52, and a pair of left and right legs 53. The smartphone support parts 51 extend parallel to each other in the front-rear direction. The charger support parts 52 extend parallel to each other in the front-rear direction. The charger support parts 52 are provided between the smartphone support parts 51. The smartphone support parts 51 and the legs 53 extend linearly from each other.

The legs 53 are inserted through the through holes 41 of the plate member 40. In this example, the legs 53 are inserted through the through holes 41 so that the rear end 52a of the charger support portion 52 and the front surface 40b of the plate member 40 are in contact with each other or in close proximity with a gap of about several millimeters between them.

As shown in FIG. 22, the mobile terminal stand 3 stands on its own with the plate member 40 tilted backward by seating the lower end 40a of the plate member 40 and the tips 53a of both legs 53 on the installation surface S.

The mobile device stand 3 has a mobile device support section 60 and a sound reflection section 70.

As shown in Figs. 23 and 24, the mobile terminal support part 60 is a component that can support a smartphone 100, as an example of a mobile terminal, in a horizontal position with the entire front surface 100f exposed. The mobile terminal support part 60 is composed of the center of the front surface 40b of the plate member 40 and both smartphone support parts 51 of the leg member 50. The distance between the two smartphone support parts 51 is selected to be a distance that allows both the left and right sides of the smartphone 100 placed horizontally to be stably supported by the two smartphone support parts 51.

As shown in Figs. 21 and 22, the mobile terminal support section 60 has a power supply support section 80 for supporting the disk-shaped wireless power supply 200. The power supply support section 80 is composed of the center of the front surface 40b of the plate member 40 and both charger support sections 52 of the leg member 50. The power supply support section 80 has a backrest section 81 that supports the wireless power supply 200 from behind. The front surface of the backrest section 81 is tilted backward with respect to the horizontal plane. The center of the front surface 40b of the plate member 40 functions as the backrest section 81.

The wireless power feeder 200 has a built-in power transmission coil 34. The power transmission coil 34 is provided near the front surface of the wireless power feeder 200 (the upper surface when laid flat).

[Action and Effects]
The mobile terminal stand 3 configured as described above can support the smartphone 100 by the mobile terminal support part 60. The work required of the user to support the smartphone 100 on the mobile terminal support part 60 is only to bring the lower end of the smartphone 100 into contact with the smartphone support part 51 and bring the back surface 100c of the smartphone 100 into contact with the backrest part 81, i.e., the front surface 40b of the plate member 40, and lean the smartphone 100 against the mobile terminal support part 60.

With this mobile device stand 3, the user can support the smartphone 100 on the mobile device support part 60 with only the extremely simple task of leaning the smartphone 100 against the mobile device support part 60. With the smartphone 100 leaned against the mobile device support part 60, the user can listen to the sounds emitted from both sound emitting parts 101L and 101R while viewing the images displayed on the touch display that constitutes most of the area of the front surface 100f of the smartphone 100.

The mobile device stand 3 supports the smartphone 100 by tilting it backwards using the mobile device support part 60. In this example, the smartphone 100 is supported in a position tilted, for example, 25° to 35° from the vertical position. The smartphone 100 is supported in a stable state with its weight entrusted to the smartphone support part 51 and the backrest part 81.

The mobile terminal stand 3 can support the smartphone 100 by exposing the entire front surface 100f with the mobile terminal support part 60. Since the entire front surface 100f of the smartphone 100 supported by the mobile terminal support part 60 is exposed, the user can see and touch the entire front surface 100f of the smartphone 100. Therefore, the user can operate the smartphone 100 by touching the front surface 100f of the smartphone 100 while the smartphone 100 is supported by the mobile terminal support part 60. This operation includes an operation performed by touching a finger or a stylus pen to the touch display that constitutes most of the area of the front surface 100f of the smartphone 100, and an operation performed by touching a finger to the fingerprint sensor 104. In addition, the camera 102 can be used while the smartphone 100 is supported by the mobile terminal support part 60. Since the brightness sensor 103 is exposed, the exposure adjustment of the camera 102 based on the illuminance of the front surface 100f of the smartphone 100 or the brightness adjustment of the touch display can be performed as usual. "Normally" means the same as when the smartphone 100 is not supported by the mobile terminal support part 60 and the brightness sensor 103 is not blocked by an obstacle such as a finger.

The entire front surface 100f of the smartphone 100 supported by the mobile terminal support part 60 is exposed, and there is nothing to the left of the left end 100Ll of the smartphone 100 that would be an obstacle when the user touches the front surface of the left end 100L of the smartphone 100 with his/her finger. Also, the entire front surface 100f of the smartphone 100 supported by the mobile terminal support part 10 is exposed, and there is nothing to the right of the right end 100Rr of the smartphone 100 that would be an obstacle when the user touches the front surface of the right end 100R of the smartphone 100 with his/her finger.

The mobile device stand 3 has a large sound reflection section 70 behind the smartphone 100 supported horizontally on the mobile device support section 60, so that it can suppress the backward diffusion of sound emitted from the sound emission sections 101L, 101R located at both left and right ends (left end 100L, right end 100R), and can efficiently guide the sound forward, i.e., toward the user.

In detail, the mobile terminal stand 3 has a sound reflecting section 70 that has a first portion 21, which suppresses the backward diffusion of sound emitted from the sound emitting section 101L on the left side of the smartphone 100, and can efficiently guide the sound to the user. Also, the sound reflecting section 70 has a second portion 22, which suppresses the backward diffusion of sound emitted from the sound emitting section 101R on the right side of the smartphone 100, and can efficiently guide the sound to the user.

And because the sound reflection unit 70 has the third portion 23, it is possible to more effectively suppress the backward diffusion of sound emitted from the sound emission unit 101L on the left side of the smartphone 100, and to more efficiently guide the sound to the user side. And because the sound reflection unit 70 has the fourth portion 24, it is possible to more effectively suppress the backward diffusion of sound emitted from the sound emission unit 101R on the right side of the smartphone 100, and to more efficiently guide the sound to the user side.

Therefore, the mobile terminal stand 3 can effectively utilize the acoustic characteristics of the smartphone 100 to deliver left and right sounds emitted from the smartphone 100 to the user. The user can listen to left and right sounds that effectively utilize the acoustic characteristics of the smartphone 100 while viewing the entire image displayed on the touch display that occupies most of the front surface 100f of the smartphone 100. For example, when content consisting of a video and stereo sound is played on the smartphone 100, the user can enjoy stereo sound with excellent three-dimensional effect by viewing the entire image displayed on the touch display that occupies most of the front surface 100f of the smartphone 100 and listening to left and right sounds that effectively utilize the acoustic characteristics of the smartphone 100.

The mobile terminal stand 3 configured as described above can support the smartphone 100 and the wireless power supply device 200 by stacking them one on top of the other, as shown in Figures 23 and 24, using the mobile terminal support section 60.

The only work required of the user to support the wireless power feeder 200 on the mobile terminal support section 60 is to bring the lower end of the wireless power feeder 200 into contact with the power feeder support section 52 and the rear surface 200c of the wireless power feeder 200 into contact with the backrest section 81, i.e., the front surface 40b of the plate member 40, and lean the wireless power feeder 200 against the mobile terminal support section 60. The cord 201 extending from the wireless power feeder 200 can be guided to the rear of the plate member 40 through a notch 42 provided at the lower end of the plate member 40.

After the wireless power feeder 200 is leaned against the mobile terminal support section 60, the smartphone 100 is leaned in front of the wireless power feeder 200, so that the smartphone 100 and the wireless power feeder 200 are supported by the mobile terminal support section 60, stacked one on top of the other. The smartphone 100 and the wireless power feeder 200 are supported in a stable state with their respective weights entrusted to the smartphone support section 51, the power feeder support section 52, and the backrest section 81.

Therefore, according to the mobile terminal stand 3 of the third embodiment, the user can support the wireless power supply 200 on the mobile terminal support part 70 in advance and supply power to the wireless power supply 200, and can support the smartphone 100 on the mobile terminal support part 70 and charge the smartphone 100 by simply leaning the smartphone 100 against the mobile terminal support part 70. While charging the smartphone 100, the user can view images displayed on the touch display that constitutes most of the area of the front surface 100f of the smartphone 100 and sounds emitted from both sound emission parts 101L and 101R. Since content can be played while charging the smartphone 100, playback interruptions due to insufficient charging do not occur. The user can enjoy streaming content distributed by Amazon (registered trademark) Prime Video, Hulu (registered trademark), NETFLIX (registered trademark), YouTube (registered trademark), etc. without worrying about interruptions due to insufficient charging.

Since there is a space between the back surface of the left end portion 100L of the smartphone 100, which is supported horizontally on the mobile terminal support portion 60 and overlapped in front of the wireless power feeder 200, and the sound reflecting portion 70, i.e., the plate member 40, chattering noise caused by direct contact between the left end portion 100L of the smartphone 100 and the sound reflecting portion 70 when the smartphone 100 outputs sound can be prevented. Since there is a space between the back surface of the right end portion 100R of the smartphone 100, which is supported horizontally on the mobile terminal support portion 60 and overlapped in front of the wireless power feeder 200, and the sound reflecting portion 70, chattering noise caused by direct contact between the right end portion 100R of the smartphone 100 and the sound reflecting portion 70 when the smartphone 100 outputs sound can be prevented.

In addition, the left and right spaces between the smartphone 100 and the sound reflecting unit 70 are partitioned left and right by the wireless power feeder 200, so sound transmitted rearward from the left end 100L and right end 100R of the smartphone 100 is guided upward and downward. This can be expected to produce an acoustic effect.
