めて好しいものである。For example, in television receivers, audio multiplex broadcasting,
With the advent of stereo broadcasting, speakers have been installed on both sides of the television receiver body. In the case of ε, if the speaker is completely fixed to the side, the sound emission direction will be perpendicular to the viewer of the television receiver, which is undesirable. A configuration has been proposed in which boxes are attached to both sides of the television receiver body so that they can be opened and closed. During viewing, the direction in which the sound is emitted from the speaker can be aligned with the viewer, which is extremely desirable in practice.

付図面を用いて説明する。In view of the fact that in such a device, the sound quality of the speaker is better when the inner volume of the speaker box is larger, the present invention provides
When the speaker box is opened, the concave portion of the audio device body communicates with the speaker box to increase the internal volume and improve sound quality. One embodiment will be described below with reference to the accompanying drawings.

第2図。On the other hand, the television receiver main body 3 is integrally provided with a recess 4 in which the speaker box 2 is housed when it is closed. When the speaker box 2 is stored in this recess 4, the second
As shown in FIG. It can be oriented almost directly in front of the camera. At this time, one surface of the speaker box 2 acts to close the opening surface of the recess 4. At this time, by providing a large number of holes 6 on this negative surface, the inner volume of the speaker box 2 can be reduced isometrically to the speaker box 2. The size can be the sum of that of the box 2 and that of the four parts 4, making it much larger than the internal volume when the speaker box 2 is housed in the recess 4 or when the speaker box 2 is alone. , it is possible to improve the sound quality. In addition,
