Description

[Detailed Description of the Invention] <Industrial Field of Application> This invention relates to a microphone with a switch, in which a switch for turning on and off a signal is attached to the main body of the microphone.

<Conventional technology> Conventionally, the switch was attached to the microphone body by tightening screws or gluing it with adhesive, but this required a lot of assembly man-hours and was difficult in mass production. It was inefficient.

Furthermore, as a conventional example of attaching a switch to a microphone body without using screws or adhesives, there is a structure as disclosed in Japanese Utility Model Publication No. 16875/1983. As shown in FIG. 5, the switch 3 is housed in a recess 2 provided in the microphone body 1, and the switch 3 has a window 5 in the center from which the knob 4 of the switch 3 protrudes, and a collar 6 around the periphery. The microphone body 1 is covered with a cover 7 having a cylindrical cosmetic case 8, and the flange 6 of the cover 7 is pressed around the notch 9 of the cylindrical cosmetic case 8 placed over the microphone body 1.

With such a structure, the switch 3 can be attached to the microphone body 1 without using screws, but the cover has a window 5 in the center from which the knob 4 of the switch 3 protrudes and a flange 6 around it. 7 has to be specially made, so
The number of parts increases, and installation of the switch 3 becomes easier. However, in order to attach a lead wire from a microphone unit (not shown) to the switch 3 and a cord that has an output plug that is the output terminal of the microphone, these leads are necessary. The wires and cords must be placed inside the microphone body 1, the ends of these lead wires and cords must be brought out through the recess 2 provided in the microphone body 1, and soldered to the terminals of the switch 3. Therefore, in advance, during the soldering work process, connect the other end of the lead wire, one end of which is connected to the microphone unit, and the other end of the cord, which has an output plug that is the output terminal of the microphone, to the terminal of switch 3. There is a problem in that the microphone unit and the switch, which are connected by these lead wires and cords, cannot be attached to the microphone main body 1 in the final assembly process of the microphone.

<Problems to be solved by the invention> This invention solves the problems of the conventional example as described above, that is, it is possible to attach the switch to the microphone body without using screws or special covers, and In advance, during the soldering process, solder the other end of the lead wire with one end soldered to the microphone unit, and the other end of the cord with the microphone output plug attached to one end, to the switch. ,
In the next assembly process, the microphone unit, switch, and cord having an output plug connected by these lead wires can be attached to the microphone body.

<Means for Solving the Problems> In order to solve the above-mentioned problems, this invention uses a microphone unit and a switch connected to the other end of a lead wire whose one end is connected to the signal output terminal of the microphone unit. a cord having one end connected to the other end of the switch and having an output plug at the other end; and a cylindrical body through which the cord passes through the cylinder and having an opening in the body for fitting the switch from the inside to the outside. The microphone body has a hole in the body that covers the cylindrical body and allows the operating knob of the switch to protrude from the inside to the outside, and the microphone body has the microphone unit and a net set for protecting it attached to the tip, and the cylindrical body A holding step for holding one of the mounting pieces of the switch with the inner surface of the microphone main body is formed in the opening in the body of the microphone body into which the switch is fitted, and the inner surface of the microphone main body is provided with a holding step for holding one of the mounting pieces of the switch with the inner surface of the microphone main body. The present invention provides a microphone with a switch in which a concave portion is formed along the inner surface for locking the other mounting piece.

<Function> This invention uses the above-mentioned means to connect the switch to the microphone unit via the lead wire in advance in the soldering work process, and to connect the cord passed through the cylindrical body to the switch. In the next assembly process, the switch is fitted into the opening of the body of the cylindrical body from the inside to the outside, and one mounting piece of the switch is brought into contact with the clamping step formed in the opening. Fit the switch into this opening, and while covering the microphone body from the rear of the cylindrical body, make the operation knob of the switch protrude from the inside to the outside through the hole in the body of the microphone body, and then insert the other side of the switch. When the mounting piece is placed over the recess formed on the inner surface of the microphone body so as to be locked therein, one of the mounting pieces of the switch is clamped between the clamping step of the opening of the cylindrical body and the inner surface of the microphone body. Then, the other mounting piece of the switch is locked into a recess formed on the inner surface of the microphone body, and the switch is mounted. Finally, the microphone unit is fitted to the front end of the microphone body, and a net set for protecting the microphone unit is attached to complete the microphone.
