Description

Wireless earphone microphone. {WIRELESS EARPHONE-MIKE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an earphone microphone, and more particularly, to an earphone microphone for use in a communication terminal device such as a cellular phone, a PHS, or the like.

According to the conventional earphone microphone type, a separate speaker and a microphone, in which the speaker and the microphone are separated, are roughly divided into one body installed together in one housing.

In both types, however, the speaker and microphone are connected to the main body of a cellular phone, PHS through a cord and a plug installed at the end of the cord.

Referring to the conventional detachable earphone microphone according to Figure 7,

Generally, this is a hole insertion type earpiece which is widely used for communication equipment or sound equipment. The earphone part 51 and the plug part 52 are connected by a cord 53, and the microphone part 54 is arranged at an intermediate position of the cord 53. It is. In addition, the earphone microphone is connected to a communication terminal such as a mobile phone or a PHS with a cord 53. The voice signal is transmitted from the mobile phone to the earphone unit 51 of the earphone microphone through the code 53, and the voice signal collected from the micron unit 54 of the earphone microphone is transferred to the mobile telephone.

As mentioned above, the main reason why the use of the earphone microphone, which is a kind of hand-free device, is not active despite the prohibition or restriction of the use of mobile phones or the like during driving is the existence of code 53.

In other words, the conventional earphone microphone has a structure that cannot be used unless it is connected to a communication terminal such as a mobile phone or a PHS by using a cord 53. Therefore, when carrying, the cord 53 must be bundled or folded, and especially when an incoming call is used. There's a lot of times when it's time to pull code 53 in a hurry and it takes quite a while before code 53 gets tangled and actually becomes available.

Also, if you are in a state where other people are not observed, such as driving a car, put your cell phone in your suit's pocket or place it in a special holder installed in your car. In many cases, the earphone microphone body is caught in the shift lever or seat belt of the seat, or the cord 53 is entangled.

Also, when the driver gets out of the car, it often happens that they unload their mobile phone unconsciously. At this time, when the car door is closed while the earphone microphone main body connected to the mobile phone remains in the car, the cord 53 may be cut off and the earphone microphone main body may be broken.

As a result, the conventional earphone microphone has received high praise from users and related parties in terms of function and effect, but most people are reluctant to use the cord 53 because it impairs usability.

The present invention is proposed in accordance with the problem of the earphone microphone with a conventional cord as described above,

The earphone microphone is divided into a mother machine and a magnetic machine, and the plug of the mother machine is connected directly to a communication terminal such as a mobile phone through a short cord, or there are various problems between the mother machine and the magnetic machine. It is an object of the present invention to provide a high-variability wireless earphone microphone that has eliminated the code causing the problem.
