Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a microphone mounting device incorporated in a communication device such as a telephone or a facsimile.

(Prior Art) A microphone mounting device for a communication device of this type that has been already proposed is configured as shown in FIG.

That is, in FIG. 5, for example, a locking claw portion 1a and a rising microphone pressing piece 1b are formed at the front end of the base body 1 of the telephone, and the locking claw portion 1a and the rising microphone pressing piece 1b are formed. Is detachably provided so that the engaging portion 2a of the housing cover 2 is engaged and the microphone housing chamber 3 is formed. The housing cover 2 is formed so as to cover the base body 1, and a sound passage hole 4 is formed in the front end of the housing cover 2 so as to communicate with the microphone storage chamber 3. Has been done. further,
A microphone case 6 having a built-in microphone 5 is mounted in the microphone housing chamber 3 in which the sound passage hole 4 is located so as to be pressed forward by the rising microphone pressing piece 1b.

Therefore, the microphone mounting device of the communication device described above,
By previously inserting a microphone case 6 having a built-in microphone 5 into the front end portion of the housing cover 2 and engaging the engaging portion 2a of the housing cover 2 with the locking claw portion 1a of the base body 1, The microphone case 6 is mounted so that the back part of the microphone case 6 is pressed forward by the rising microphone pressing piece 1b of the base body 1.

(Problems to be solved by the invention) However, since the cover molding die of the housing cover 2 used in the microphone mounting device of the communication device described above has a so-called slide structure, this cover molding die is expensive. Not only can it not be provided inexpensively, but in order to improve the adhesion of the microphone case 6, the rising microphone pressing piece 1b of the base body 1 is required, and the shape of the base body 1 is complicated. There are difficulties such as

On the other hand, in place of the above-described microphone mounting device for the telephone, the cover molding die of the housing cover 2 is not made to have a sliding structure, so that the sound passage hole 4 is communicated with the microphone storage chamber 3 in the upper portion of the housing cover 2. Although it is possible to form the holes in this way, this not only lowers the sound collection efficiency of the microphone 5, but also has a drawback that dust or the like is accumulated in the sound passage hole.

The present invention has been made in view of the above-mentioned circumstances, and makes it possible to provide this cover molding die at low cost without making the cover molding die of the housing cover into a sliding structure, and at the same time, to make a sound during assembly. An object of the present invention is to provide a microphone mounting device for a communication device in which a through hole is formed and a microphone is pressed against a housing cover to improve adhesion.

[Constitution of device]

(Means and Actions for Solving Problems) In the present invention, a housing cover to be capped and mounted on a base body is detachably provided, and a storage chamber is formed at one corner of the housing cover. A storage frame is provided, a microphone case with a built-in microphone is inserted into the storage frame, and a ridge portion is formed in a part of the microphone case. An outer wall of the storage frame in which the ridge portion is located. A vertical groove is formed in the microphone case, and when the microphone case is inserted, a part of the vertical groove is covered with the bank portion to form a sound passage hole, and the microphone is pressed by a part of the housing cover. By improving the adhesion, simplifying the mold and assembling to save labor in mass production, it is possible to provide at low cost.

(Embodiment) An embodiment of the present invention in which the present invention is applied to a telephone will be described below.

In FIGS. 1 to 4, reference numeral 10 is, for example, a base body of a telephone as an example of communication equipment,
On the base body 10, a housing cover 11 to be capped and attached is detachably provided, and a storage frame body 13 in which a storage chamber 12 is formed is formed in a corner 11a in the housing cover 11. Is provided. In addition, a microphone case 15 having a microphone 14 built therein is inserted in the housing frame 13, and a part of the microphone case 15 has a bank portion 15a.
Are formed. Further, a vertical groove 16 is formed on the outer wall 13a of the storage frame body 13 in which the bank portion 15a is located, and a part of the vertical groove 16 is a part of the microphone case 15 described above.
At the time of assembling and inserting the above, the sound passage hole 17 is formed so as to be covered with the ridge 15a.

Therefore, now, when the microphone case 15 is assembled and inserted, by inserting the microphone case 15 having the built-in microphone 14 into the storage chamber 12 of the front end portion 11b of the housing cover 11 in advance, the storage frame body 13 can be inserted. A part of the vertical groove 16 is covered with the ridge 15a to form a sound passage hole 17, and the back of the microphone 14 itself is pressed by a part of the storage frame body 13 integrated with the housing cover 11. And attach them so that they are in close contact. After that, attach the housing cover 11 to the base body 10
It is designed to be crowned and worn on the top.

[Effect of device]

As described above, according to the present invention, a housing cover that is captively mounted on the base body is detachably provided, and a storage frame body having a storage chamber is provided at one corner of the housing cover. A microphone case with a built-in microphone is inserted in the housing frame, a ridge portion is formed in a part of the microphone case, and a vertical groove is formed in the outer wall of the storage frame where the ridge portion is located. When the microphone case is inserted, a part of the vertical groove is covered with the ridge so as to form a sound passage, so that the microphone is pressed by a part of the housing cover to be in close contact. Not only can this be achieved, but the already proposed startup microphone pressing piece of this type is also unnecessary, and the cover cover molding die and assembly of the housing cover can be simplified to save labor by mass production, and it is cheap. Can be provided to It has an excellent effect and the like.
