However, the known earphone structure still has the following disadvantages in actual use. Due to the poor texture of the inner cover, it is easy to produce permanent deformation to varying degrees with the use of time, and then the distortion rate of the microphone is increasing day by day; and The sound output by this headset is not ideal in terms of sound quality and loudness, and needs to be improved urgently.

Utility model content

The main purpose of this utility model is to provide an earphone and a microphone with a ceramic inner shell, which can effectively improve the distortion rate of the microphone by virtue of the strength and hardness of the inner shell itself, and can produce good sound quality, Loud sound.

In order to achieve the above object, the earphone provided according to the utility model has a ceramic inner shell, comprising: an earphone body formed with an accommodating portion; a speaker accommodated in the accommodating portion of the earphone body; and an inner shell made of Made of ceramic material, the inner shell covers the earphone body and is configured corresponding to the speaker.

According to the utility model, the earphone microphone provided with the ceramic inner shell includes: the outer shell, which has an accommodation groove formed inside; the speaker, which is accommodated in the accommodation groove of the outer shell; and the inner shell, Made of ceramic material, the inner housing covers the outer housing and corresponds to the horn configuration.

According to the earphone and the microphone with the ceramic inner shell provided by the utility model, since the inner shell is made of ceramic material, it has sufficient strength and hardness, so the distortion rate of the microphone can be effectively improved, and the sound quality is good. , loud sound.
