Description
Technical field
The present invention relates to headphone acoustic technical fields, are specifically related to a kind of noise cancelling headphone.
Background technique
Earphone is a pair of of converting unit, it receives the electric signal that media player or receiver are issued, using close to ear
Piece loudspeaker convert it into the sound wave that can be heard, it is usually separable with media player, utilize plug to connect
It connects.Benefit is can to listen to sound equipment alone in the case where not influencing other people；Also the sound that ambient enviroment can be separated, to recording
The people that room, DJ, journey, movement etc. use under noisy environment of making an uproar is helpful.Earphone original be for phone and radio, but with
Portable electronic devices it is prevailing, earphone is chiefly used in mobile phone, walkman, radio, portable electronic game sum digit reproducing apparatus for phonotape
Deng.
The rapid development and popularization and application of portable communication, audio-visual devices, people to the quality requirement of earphone increasingly
Height, the noise reduction effect especially for earphone are to measure an important indicator of headphone quality quality, and current noise cancelling headphone is more
Number using sealing means by Noise insulati on outside, but listening environments obtain sealing while can also generate acoustic pressure inside and outside earphone
Uneven problem, influences noise reduction effect, while biggish acoustic pressure power causes to oppress to the ear-drum of user, influences comfort level.
Summary of the invention
The present invention is to overcome above situation insufficient, it is desirable to provide a kind of technical solution that can solve the above problem.
A kind of noise cancelling headphone, including shell, inner casing and the phonation unit being mounted in inner casing, the bottom sides of the shell
Edge is equipped with annular ear pad and forms ante-chamber, and the inside of inner casing forms inner cavity, shape between the outer surface of inner casing and the inner surface of shell
The first air-guiding hole is equipped at back cavity, between ante-chamber and inner cavity is connected the two gas circuit, and the second wind-guiding is equipped between ante-chamber and back cavity
Hole both makes gas circuit conducting, and third air-guiding hole is equipped between inner cavity and back cavity be connected gas circuit, back cavity and shell exterior it
Between be equipped with the 4th air-guiding hole and both make gas circuit conducting, the first air-guiding hole, the second air-guiding hole, third air-guiding hole, in the 4th air-guiding hole
It is filled with adjustable sound paper.
Further, first air-guiding hole runs through the bottom of shell and ante-chamber is connected with inner cavity gas circuit.
Further, second air-guiding hole is connected to the bottom of shell and the top of inner casing and makes ante-chamber and back cavity gas circuit
Conducting.
Further, the third air-guiding hole runs through the top of inner casing and inner cavity is connected with back cavity gas circuit.
Further, the 4th air-guiding hole runs through the top of shell and back cavity is connected with shell exterior gas circuit.
Compared with prior art, what the present invention obtained has the beneficial effect that structure of the invention novelty, before being made by air-guiding hole
Chamber, inner cavity, back cavity and earphone outside air mutually lead to and press, and improve the wear comfort of user, optimize user experience, lead
Adjustable sound paper is filled in air holes effectively external noise to be isolated, and reinforce noise reduction effect.
Additional aspect and advantage of the invention will be set forth in part in the description, and will partially become from the following description
Obviously, or practice through the invention is recognized.
