があつた。Problems to be Solved by the Invention However, in this type of microphone mounting device, in order to firmly mount the microphone 12, the diameter of the cylindrical body 12 is made sufficiently smaller than the diameter of the microphone holder 11 made of rubber or the like. 12
It is necessary to press-fit the microphone holder 11 made of rubber or the like into the cylindrical body 10, and this press-fitting operation is extremely difficult. In particular, when a speaker is installed inside a case like a telephone handset, the microphone holder 10 made of rubber or the like is also shaped like a cylinder so that the sound from the speaker does not pass through the case 9 and reach the front of the microphone 12. It is necessary to form the microphone 12 and the cylindrical body 10 so that there is no gap at all between the microphone 12 and the tubular body 10.
There was a problem in that the press-fitting work in step 2 was even more difficult.

れた吸音用の透孔である。Embodiment Figures 1 and 2 show an embodiment of the microphone mounting device of the present invention. In the figures, 1 is a case forming a handset of a telephone, etc., and 2 is integrally formed on the inner surface of the case 1. a cylindrical body for mounting a microphone; 3 is a projection for positioning the microphone integrally formed on the inner peripheral surface of the cylindrical body 2 so as to extend in the axial direction of the cylindrical body 2; 4 is one end of the projection 3; A ring 6 is formed integrally with the bottom surface of the microphone insertion recess 7 formed by the case 1 and the cylindrical body 2 to position the microphone 5. The jetty 8 is a sound-absorbing through hole formed in the center of the bottom surface of the recess 7.

In this case, since the tapered portion 4 is formed at one end of the projection 3 according to the above embodiment, this acts as a guide. The microphone 5 can be accurately connected to the cylindrical body 2 by the action of the protrusion 3 and the jetty 6.
is positioned at the center of the In this way, when the microphone 5 is inserted into the cylindrical body 2, a gap corresponding to three protrusions is formed in a portion where the protrusion 3 is not present. This gap is filled with an elastic adhesive such as epoxy resin to completely fix the microphone 5 to the cylindrical body 2.

ないという利点を有する。Effects of the invention As is clear from the above embodiment, the present invention forms a plurality of protrusions on the inner peripheral surface of the cylindrical body, and uses these protrusions to position the microphone inserted into the cylindrical body. The microphone is fixed to the cylindrical body by filling an elastic adhesive between the cylindrical body and the microphone holder. It can be inserted into the body and fixed, making the installation process much easier. especially,
According to the present invention, the microphone is attached using an elastic adhesive, so there is almost no problem with vibrations, and even when inserting it into a cylindrical body, it is simply inserted without having to be forcefully press-fitted as in the past. It is sufficient to insert or slightly press fit, and has the advantage that the insertion work is extremely simple. According to the present invention, the elastic adhesive completely closes the gap between the inside of the case and the front of the microphone, making it possible to completely close the gap between the inside of the case and the front of the microphone. It has the advantage that there is no problem even if it is used in various types of equipment.
