Earphone

Abstract

The invention discloses an earphone. The earphone comprises an earphone main body into which a loudspeaker is embedded, and an ear cap, wherein the earphone main body is provided with a hollow extension portion which is communicated with the inside of the earphone main body; the hollow extension portion is sleeved with the ear cap; meanwhile the ear cap is further provided with a small hole which is communicated with the inside of the hollow extension portion; a voice diaphragm of the loudspeaker faces a channel which is communicated with the small hole of the hollow extension portion; the peripheral wall of the hollow extension portion is provided with more than one exhaust groove. The peripheral wall of the hollow extension portion is provided with the exhaust groove, and air in the small hole of the ear cap can be exhausted from the exhaust groove when the small hole of the ear cap is blocked and the ear cap is connected to the hollow extension portion in a sleeved way due to error operation of a user, so that deformation of the voice diaphragm of the loudspeaker due to extrusion of the air in the small hole into the earphone main body is effectively avoided, and the quality of the earphone is ensured.

Description

Technical field [0001] The invention relates to an earphone, especially an in-ear earphone. Background technique [0002] With the development of society and the advancement of science and technology, the existing earphones are becoming more and more sophisticated. In order to make the in-ear earphones embedded in the human ears, it can make people feel more comfortable. This type of earphones generally will be socketed There is a flexible ear cap with a small hole communicating with the inside of the earphone, so that the sound emitted by the speaker inside the earphone can be transmitted to the human ear through the small hole. Accordingly, the speaker The sound membrane faces the small hole so that the sound can be better transmitted. [0003] Since the size of each person’s ear cavity is different and their personal preferences are different, the user will change different ear caps on the earphone according to the size and preference of the individual’s ear cavity. During the ...

AI Technical Summary

Problems solved by technology

[0003] Since each person's ear cavity size is different and personal preferences are different, users will change different ear caps on the earphones according to their personal ear cavity size and preferences. During the process of changing ear caps, due to operational errors, It is easy to block the small holes on the ear caps by hand, and when the ear caps are set on the earphones, they will generally be in close contact with the socket part of the earphones. The air in the small hole and the air on the socket of the earphone squeeze the sounding membrane of the speaker. Since the sounding membrane of the speaker is a very fine part, it is easy to deform under the extrusion of the air and affect its pronunciation. effect, which in turn affects the sound quality of the earphones, reduces the quality of the earphones, and affects the normal use of the earphones by the user.
