Description

[Detailed Description of the Invention] This invention relates to a microphone device that can be detachably attached to a headphone.

Headphones, which have headphone units attached to both ends of a headband, are widely used by a single person to enjoy radio broadcasts and playback of records or magnetic tapes without being disturbed by external noise. Furthermore, as mentioned above, headphone units are also used to play back records and magnetic tapes for language learning such as English conversation because they are not disturbed by external noise. In language learning using magnetic tape, the teacher's voice is recorded on one of the multiple tracks of the tape, and the learner's voice can be recorded on the other tracks following the playback of the teacher's voice. There are things that are. In this type of learning, a headphone to which a microphone is integrally attached is used. However, such a headphone with a microphone is inconvenient when simply listening to the teacher's voice outdoors, and furthermore, the microphone can get in the way when listening to radio broadcasts or playing records. There is.

Therefore, headsets with microphones have been provided in which a microphone is removably attached to the headphone using screws, etc., but it is not easy to attach and detach, and many parts are required for installation, and even one part can be lost. This resulted in drawbacks such as the fact that the microphone could not be fixed to the headphone.

This invention improves the above-mentioned drawbacks and provides a microphone device that has a simple structure and can be easily attached to and detached from a headphone.

An embodiment of this invention shown in the drawings will be described below. This microphone device 1 has a hollow microphone arm 3 having a microphone unit 2 at one end, and a connection cord 4 is attached to the other end of the microphone arm 3. Connection code 4
One end is connected to the microphone unit 2 through a hollow part in the microphone arm 3, and the other end is connected to a plug 5 that is connected to a recording terminal of a language learning machine, tape recorder, or stereo device. A microphone support 6 preferably made of synthetic resin or synthetic rubber having a high coefficient of friction is inserted into the microphone arm 3 . The microphone support 6 has a through hole 7 through which the microphone arm 3 passes, and a headphone 8.
The fitting recess 10 fits into the protrusion 9 provided in the fitting recess 10 . In this case, the protrusion 9 is attached to a pivot shaft 13, which is attached at one end to the headband unit 12, in order to pivotably support the headphone unit 12 at one end of the headband 11, as shown in detail in FIG. It also serves as a holding part that pivotally holds the other end. . In order to securely attach the microphone support 6 to the headphone 8,
A notch 14 is formed in the fitting recess 10 so that the headband 11 is also fitted, and the peripheral edge of the fitting recess 10 slightly protrudes inward, and this protrusion allows the headband to be fitted into the protrusion 9 with a snap action. Fixed.

With the above structure, when the microphone device 1 is fixed to the headphone 8, the microphone support 6 is attached to the protrusion 9 of the headphone 8.
Reliable fixation can be achieved simply by fitting into the fitting recesses 10. Further, when the microphone device 1 is to be removed from the headphone 8, it can be easily separated by pulling the projection 9 and the fitting recess 10 in opposite directions. In addition, the microphone support 6 is made of a material with a high coefficient of friction, so it does not slip easily, and simply inserting the microphone arm 3 into the through hole 7 allows
The position of the microphone unit 2 does not change due to the weight of the microphone unit 2 and the microphone arm 3. Moreover, the microphone support 6 of the microphone arm 3 can be fixed by fixing the microphone support 6 and pulling or pushing the microphone arm 3 with a somewhat strong force.
Since the length from the microphone unit 2 to the microphone unit 2 can be changed, the microphone position can be adjusted very easily.

In the above embodiment, the protrusion 9 also serves as a holding part for the pivot shaft 13, but it goes without saying that a protrusion for a fitting recess may simply be provided at one end of the headband 11. Also, to adjust the angle of the microphone,
The middle portion of the microphone arm may be constructed from a flexible pipe such as a spiral pipe. On the other hand, the microphone support 6 is made of synthetic resin with a low coefficient of friction, such as Teflon (trade name).
It may be formed by, etc. However, in this case,
It is necessary to design the fitting recess 10 to fit more tightly into the projection 9.
