  Here, on the front surface 7a of the second member 7, a communication groove 50 that connects the end portion 531a of the groove 53a and the end portion 531b of the groove 53b is formed.

(Main effects of this form)
As described above, the portable electronic device stand 1 according to the present embodiment is joined to the first member 6 formed on the front surface of the device mounting portion 2 on which the portable electronic device 10 is mounted and the rear surface of the first member 6. The second member 7 has first and second sound wave paths 5a and 5b that connect the openings 51a and 51b formed in the device mounting part 2 and the sound holes 54a and 54b formed on the front surface. Yes. For this reason, if sound is reproduced in the portable electronic device 10 with the portable electronic device 10 mounted on the device mounting portion 2, the sound is output from the sound holes 54a and 54b. Further, since the first sound wave path 5a and the second sound wave path 5b are formed on the left and right sides of the device mounting portion 2 from the left and right sides, the sound can be output stereophonically from the portable electronic device stand 1.

  Large-diameter sound holes 54a and 54b are formed on the left and right sides of the device mounting portion 2 from both the left and right sides. Moreover, the first member 6 and the second member 7 are made of wood. For this reason, the design property of the stand 1 for portable electronic devices itself and the design property in the state which attached the portable electronic device 10 to the stand 1 for portable electronic devices can be improved. Moreover, since the 1st member 6 and the 2nd member 7 are wooden, since unnecessary reflection etc. are hard to generate | occur | produce, acoustic performance can be improved.

  Here, the portable electronic device stand 1 has grooves 53a and 53b formed on the joint surface between the first member 6 and the second member 7 through the acoustic chambers (resonance chambers) of the first acoustic path 5a and the second acoustic path 5b. ). Therefore, according to the portable electronic device stand 1 of the present embodiment, it is possible to enhance the music playback capability and the like. Further, unlike the case where the box-shaped acoustic chamber is partitioned, a large number of members are not required. Therefore, the portable electronic device stand 1 of the present embodiment can be efficiently manufactured and can be thinned.

  The grooves 53a and 53b are cross-sectional areas from the end portions 531a and 531b communicating with the openings 51a and 51b through the through holes 52a and 52b toward the end portions 539a and 539b communicating with the sound holes 54a and 54b. Is expanding continuously. Therefore, the grooves 53a and 53b can function as an acoustic room, and the sound output from the portable electronic device 10 can be expanded and output.

  Further, the grooves 53a and 53b are formed collectively on the joint surface (front surface 7a) of the second member 7 with the first member 6. Therefore, the portable electronic device stand 1 can be efficiently manufactured. The cross-sectional area of the grooves 53a and 53b is extended from the end portions 531a and 531b communicating with the openings 51a and 51b through the through holes 52a and 52b toward the end portions 539a and 539b communicating with the sound holes 54a and 54b. Even in the case of a configuration in which the width is continuously expanded, the width and the depth may be continuously increased during the grooving. Accordingly, the grooves 53a and 53b having a predetermined shape can be efficiently formed.

Further, since the grooves 53a and 53b are bent and extended in a U shape at a plurality of locations, the grooves 53a and 53b can be lengthened without increasing the size of the portable electronic device stand 1. Therefore, the acoustic performance of the first acoustic path 5a and the second acoustic path 5b can be enhanced.

  Further, the end portion 531 a of the groove 53 a and the end portion 531 b of the groove 53 b are connected via the communication groove 50. For this reason, since the sound output from the speaker holes 11a and 11b of the portable electronic device 10 is not uttered by the first sound path 5a and the second sound path 5b, the acoustic performance of the first sound path 5a and the second sound path 5b. Can be increased.

(Another embodiment of the present invention)
In the above embodiment, two sets of sound wave paths (the first sound wave path 5a and the second sound wave path 5b) are formed. However, the present invention may be applied to a stand for a portable electronic device having one sound wave path. .

  In the above embodiment, the grooves 53a and 53b are collectively formed on the front surface 7a of the second member 7. However, the grooves 53a and 53b are collectively formed on the rear surface 6b of the first member 6, A configuration in which 53a and 53b are formed on both the front surface 7a of the second member 7 and the rear surface 6b of the first member 6 may be employed.
