Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a speaker mounting structure inside a handset such as an automobile telephone.

[Conventional technology]

A conventional speaker mounting structure of this type is shown in FIG. That is, the cover 1 of the handset is provided with the slit hole 1a for allowing the sound of the speaker 3 to pass therethrough, and the dustproof net 4 is attached to the inside so as to prevent dust from entering. And
The speaker base 6 made of a flexible material is attached to the case 2, the speaker 3 is placed on the speaker base 6 upward, and the cover 1 is put on the case 2, so that the speaker 3 is provided between the cover 1 and the case 2. The speaker 3 is attached by sandwiching.

On the other hand, another example is shown in FIG. In this example, on the contrary, the case 2 of the handset is provided with a slit hole 2a for outputting the sound of the speaker 3, and the dustproof net 5 is attached to the inside of the case 2 so as to prevent dust from entering. Then, a speaker frame 8 made of a flexible material having a shape that does not close the slit hole 2a is mounted on the dustproof net 5, and the speaker 3 is placed on the speaker frame 8 downward. In addition, the flexible material 7 is attached to the inside of the cover 1 at a position corresponding to the rear portion of the speaker 3, and the cover 1 is put on the case 2 and fixed to the case 2, so that the flexible material 7 is attached to the speaker 3. The speaker 3 is attached by sandwiching the speaker 3 between the cover 1 and the case 2 while pressing the speaker 3 toward the rear part.

[Problems to be solved by the device]

In the conventional mounting structure described above, in the case of FIG. 3, the slit hole 1a for producing the sound of the speaker 3 is provided only in the cover 1, and the case 2 is not provided with the slit hole. The sound of the speaker 3 is emitted only from the cover side. On the contrary, in the case of FIG.
Since the slit hole 2a is provided only on the side and not on the cover 1, the sound of the speaker 3 is emitted only from the case side. That is, in the conventional speaker mounting structure, the sound of the speaker is limited to one direction of the cover or the case, and it is possible to cope with the case where the sound is desired to come out in the opposite direction depending on the usage state of the telephone. However, there is a problem that the utility value of the handset is low.

It is an object of the present invention to provide a speaker mounting structure for a handset that allows the speaker to emit sound from any direction on the cover side or the case side.

[Means for Solving the Problems]

In the speaker mounting structure of the present invention, slit holes for emitting speaker sound are provided on the opposing surfaces of the cover and case constituting the handset, and a dustproof net is attached to the inner surface of these covers and the case. In a speaker mounting structure in which a speaker is sandwiched between a case and a speaker, when mounting the speaker toward the cover side, a slit hole on the case side is closed on one surface of the speaker and a back surface of the speaker is supported on the opposite surface. A stand, a speaker frame that is attached to the inner surface of the case when the speaker is installed toward the case side, and supports the peripheral portion of the speaker, and closes the slit hole on the cover side and abuts on the back surface of the speaker The speaker base is provided with a flexible material, and the speaker frame, the speaker frame, and the flexible material are selectively used to make a speech. The towards one of the cover and the case are configured to be decorated.

[Action]

In the above-described configuration, the speaker base, the speaker frame, and the flexible material are appropriately arranged and the speaker is installed toward the cover side or the case side, so that the sound of the speaker is output from any direction on the cover side or the case side. It will be possible.

〔Example〕

 Next, the present invention will be described with reference to the drawings.

1 and 2 are sectional views of an embodiment of the present invention.
It is the figure which showed the different attachment state. As shown in these figures, here, a slit hole 1 for outputting the sound of the speaker 3 is provided in each of the cover 1 and the case 2 of the handset.
a and 2a are provided. Dustproof nets 4 and 5 are attached to the inside of the cover 1 and the case 2 through slit holes 1a and 2a to prevent dust from entering the handset.

When the speaker 3 is attached to the cover 1 side, the speaker base 6 made of a flexible material having a shape capable of closing all the slit holes 2a of the case 2 of the handset as shown in FIG. And the speaker 3 is placed upward on the speaker base 6. Then, by covering the case 2 with the cover 1 and fixing the cover 1 to the case 2, the speaker 3 can be sandwiched between the cover 1 and the case 2 and fixed in the handset.

On the other hand, when the speaker 3 is attached to the case 2 side, as shown in FIG. 2, a plate-shaped flexible material 7 formed to cover all the slit holes 1a of the cover 1 is attached to the inside of the cover 1. Keep it. On the other hand, inside the case 2, a speaker frame 8 made of a flexible material is fixed around the slit hole 2a, and the speaker 3 is placed on the speaker frame 8 downward. Then, the cover 1 is put on the case 2 and fixed to the case 2, so that the flexible material 7 is pressed against the back surface of the speaker 3, and the speaker 3 is sandwiched between the cover 1 and the case 2 via the flexible material 7. So that it is fixed.

Therefore, in the structure of this handset, the speaker base
6, just change the flexible material 7, speaker frame 8, etc.,
The speaker can be attached to the cover 1 side or the case 2 side arbitrarily. This makes it possible to increase the utility value of the handset.

[Effect of device]

As described above, according to the present invention, the cover and the case are provided with the slit holes for outputting the speaker sound respectively, and the speaker base, the speaker frame, and the flexible material are appropriately arranged to cover the speaker on the cover side or the case. Since it can be installed toward the side, the sound of the speaker can be emitted from any direction on the cover side or the case side, and the utility value of the handset can be enhanced.

Further, in the present invention, the speaker frame and the flexible material are used when the speaker faces the case so that the cover can be attached to the case after the speaker is attached to the case.
The speaker base is used when the speaker faces the cover side. By selecting different mounting members depending on the speaker orientation in this way, the speaker and cover can be attached to the case, and the handset assembly work can be performed. There is also an effect that can be easily performed.
