Personnel can be implemented as basis, and this technical side is will be understood that when the combination appearance of technical solution is conflicting or can not realize
The combination of case is not present, also not within the protection domain of the requires of the utility model.
The utility model is further elaborated below in conjunction with the accompanying drawings.
Cavity in the present embodiment on auricular concha 1 is the ante-chamber of earphone, and bearing 13 is used to place noise reduction miaow 4.
A kind of preceding cavity configuration of earphone, the back cavity of the ante-chamber and earphone are not communicated with；It is equipped with the ante-chamber：
Adjusting cavity for the cavity size for adjusting ante-chamber；Adjust cavity and include chamber body 3 and for annular seal space
The sealing cover 2 of body；For the loud-speaker surface 11 of the loudspeaker output sound in earphone, the loud-speaker surface 11 is equipped with microphone；With
The string holes of ante-chamber is passed through in the transmission line of microphone；The face that quiets down that microphone is used to receive sound is oppositely arranged with loud-speaker surface；For preceding
The exhausting-gas hole of chamber exhaust；The loud-speaker surface side, which is equipped with, is used for the air hole that loudspeaker is breathed freely.It is additionally provided with ante-chamber for adjusting
The tuning cotton of earphone tonequality；Tuning cotton includes the first tuning cotton 5 and the second tuning cotton 6, wherein, the first tuning cotton 5 and second
Tuning cotton 6 is inertia cotton.
Microphone in above-mentioned is noise reduction miaow.
The opening edge of ante-chamber is along equipped with the ear muff fixing piece 10 for being used to install earphone ear muff, and the ear muff fixing piece is with before
The opening edge edge of chamber is connected by connector 8；The opening edge of ante-chamber is along with being equipped with the first sealing ring 7 between connector, and described the
One sealing ring 7 is used for the opening edge edge for sealing ante-chamber and the gap between connector；It is equipped between ear muff fixing piece and connector
Second sealing ring 9, second sealing ring 9 are used to seal the gap between ear muff fixing piece and connector.
In the utility model, air penetrability of the loudspeaker in ante-chamber air hole；The placement position of noise reduction miaow, i.e. noise reduction miaow group
After dress miaow set 12, its positive (quiet down face) is face with the speaker diaphragm assembled on earphone, ensures noise reduction miaow maximum
Quiet down effect, is conducive to the noise reduction of earphone entirety；Noise reduction miaow is connected with the miaow line of transmission telecommunications number, and miaow line needed line
Hole, miaow hole cable-through hole from front cavity lead to behind weld with the PCBA in earphone, but cable-through hole cannot pass through back cavity and draw again
Go out, the preceding money and cereal of such earphone is identical with back cavity meeting, does not reach the effect that front/back cavity need to make individual cavity, into without profit
