Abstract

PURPOSE:To improve the sound characteristics, by increasing the inner volume of a speaker box at opening than that at closing. CONSTITUTION:A television receiver main body 3 is provided with a recess 4 containing a speaker box 2. In containing the speaker box 2 in the recess 4, the front surface of the speaker box 2 is made almost the same plane as the surface of the main body 3. In opening the box 2, the speaker can be directed front to the listener. In this case, one side of the speaker box 2 acts like closing the opening surface of the recess 4. A lot of opening holes 5 are provided on one surface, allowing to make the inner volume of the speaker box 2 to that of the recess 4 equivalently.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a speaker device in an audio device such as a television receiver or a radio receiver. The purpose is to improve the sound quality when

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.

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.

Figures 1 to 3 show the case where the audio device is a television receiver, with Figures 1 and 3 showing the speaker box open and Figure 2 showing the speaker box closed. . Speaker box 2 with built-in speaker 1
The front end thereof is attached to both sides of the television receiver main body 3 so that it can be opened and closed (rotated).

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,
Figure 2.

In FIG. 3, 6 is a cathode ray tube.

Although the above example uses a television receiver as an example,
Needless to say, the present invention can also be applied to other audio products.

As described above, according to the present invention, when the speaker box provided to be openable and closable with respect to the audio device main body is opened, a hole is opened in the speaker box so that the speaker box storage recess of the audio device main body and the speaker box communicate with each other. By providing the speaker box, the internal volume when the speaker box is open can be made larger than when it is closed, and the sound quality characteristics can be improved.
