[Problems to be solved by the invention]
However, in the above-described conventional microphone holding structure, the microphone holder can be integrated only with a member that is difficult to transmit to the microphone holder due to external force such as an elastic sheet for a push button. However, there is a problem in that it is difficult to reduce the cost by simplifying the structure due to structural limitations.
[0004]
The present invention solves the above-described conventional problems, and an object thereof is to provide an inexpensive microphone holding structure with a simple structure.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, according to the present invention, the connecting portion between the microphone holder and the cover of the external input / output terminal is integrally formed in a U-shape, and the connecting portion is press-contacted by the rib provided on the housing and the printed board. By clamping, even if an external force is applied to the external input terminal, it is not transmitted to the microphone holder.
[0006]
As described above, even if the microphone holder is integrally formed with the cover of the external input / output terminal to which external force is applied, it is possible to prevent the external force from being transmitted to the holder. An integral holding structure is obtained.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
According to the first aspect of the present invention, there is provided a handset-type telephone provided with a microphone for transmission at one end of the housing and an external input / output terminal at the bottom or side of the housing. The microphone holding structure is characterized in that the cover of the output terminal is integrally formed so that the connecting portion is U-shaped, and the housing is provided with a rib that can be inserted into the U-shaped connecting portion. In addition, it is possible to realize an integral holding structure of a microphone for transmission with a simple structure and at a low price, and to prevent loss of the cover for the external input / output terminal.
[0008]
In the invention according to claim 2, the holder is attached to the microphone so that the top of the holder is pressed against the wall of the housing from the inside, and the rib provided on the housing is inserted into the U-shaped connecting portion. 2. The microphone holding structure according to claim 1, wherein the printed circuit board to which the external input / output terminals are attached is fixed to the housing in the state where the microphone holder is attached to the microphone. In addition to preventing the intrusion of noise, the microphone body can be prevented from vibrating, and can be protected from the mechanical external force applied to the microphone. The mechanical external force applied to the cover of the external input / output terminal is transmitted to the microphone holder. It has the effect that it can be made difficult.
[0009]
Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 3.
(Embodiment 1)
FIG. 1 is a partial longitudinal sectional view illustrating a main part of a handset telephone to which a microphone holding structure of the present invention is applied, FIG. 2 is an exploded perspective view of the main part of the present invention, and FIG. It is a perspective view of a part.
[0010]
In this embodiment, in addition to providing the transmitter 2 inside one end of the housing 11 suitable for grasping, an operation unit 5 in which push buttons 4 for dial and function are arranged in parallel is provided near the center. In addition, inside the operation unit 5, an elastic sheet 7 called a rubber contact in which a domed elastic receiving portion 6 with a movable contact is arranged in parallel with each push button 4, and a movable contact of the elastic receiving portion 6 is provided. The printed circuit board (printed wiring board) 8 provided with a fixed contact corresponding to the above is arranged in a superposed manner, so that only when the push button 4 is retracted, the movable contact is made against the elastic receiving portion 6. From FIG. 4 to FIG. 4, it is configured so that it can be contacted, and in addition to such a push button switch, an electrical component (not shown) necessary for the push button switch and a microphone 9 for transmission are provided. In FIG. Is the same as that of the conventional technology that was bright.
[0011]
In addition to the above-described configuration, the present embodiment further includes an external input / output terminal 12 fixed to the printed circuit board 8 on the bottom or side of the housing 11. The holder 13 of the microphone 9 and the external input / output terminal 12 The cover 14 is integrally formed so that the connecting portion 15 has a U-shape. During assembly, the holder 13 is fitted into the microphone 9, and the printed circuit board 8 is fixed to the housing 11 with the rib 16 provided on the housing 11 inserted into the U-shaped connecting portion 15. As a result, the connecting portion 15 can be pressed and held between the rib 16 and the printed circuit board 8, and the mechanical external force applied to the cover 14 of the external input / output terminal 12 can be prevented from being transmitted to the microphone holder 13. it can. Therefore, even the cover 14 of the external input / output terminal 12 to which a mechanical external force is applied can be integrated with the holder 13, and a simple structure and an inexpensive microphone holding structure can be realized. In addition, loss of the cover 14 of the external input / output terminal 12 can be prevented.
[0012]
In the above description, an example of a configuration in which only the microphone holder 13 and the cover 14 of the external input / output terminal 12 are integrally formed has been described. In addition, the elastic sheet 7 for a push button similar to the prior art is used. It is also possible to mold it integrally.
[0013]
【The invention's effect】
As described above, according to the present invention, the connecting portion between the microphone holder and the cover of the external input / output terminal is integrally formed in a U-shape, and the connecting portion is press-clamped by the rib provided on the housing and the printed board. This prevents mechanical external force applied to the cover of the external input / output terminal from being transmitted to the microphone holder, and even the cover of the external input / output terminal to which mechanical external force is applied is integrated with the microphone holder. It can be molded, and an effect is obtained that a simple structure and an inexpensive one-piece holding structure for a microphone for transmission can be obtained.
