Refering to Fig. 1 and Fig. 2, first embodiment provides a kind of earphone, including：Housing 100, loudspeaker 300, main microphon 500
With noise reduction microphone 600；
The one first sound chamber 200 of formation of housing 100, loudspeaker 300 are arranged in the first sound chamber 200, and user is received by loudspeaker 300
Listen the audio signals such as voice and music；
Main microphon 500 is used for the signal for receiving source of sound 400, and main microphon 500 is on housing 100；When user wears
During earphone, main microphon 500 is close to source of sound 400, i.e., close to face, to receive apparent voice.
Noise reduction microphone 600 is used to receive environmental noise, and noise reduction microphone 600 is on housing 100；
On the extended line of line of the noise reduction microphone 600 between main microphon 500 and source of sound 400, it will be understood that noise reduction
The line of microphone 600, main microphon 500 and the three of source of sound 400 is in alignment.
The earphone of the present embodiment will be arranged on for receiving sound source signal for the noise reduction microphone for receiving environmental noise
(i.e. for receiving the noise reduction microphone of environmental noise, for receiving sound on the extended line of line between main microphon and source of sound
The main microphon of source signal and the line of source of sound three are in alignment), so as to form the microphone beam with directive property, only
It is more sensitive to the sound from source of sound such as face direction, and the environmental noise come from other directions is then eliminated significantly, because
This, can provide a clear noiseless voice to recipient.
It is mutually isolated between noise reduction microphone 600 and loudspeaker 300 in the present embodiment.Due to noise reduction microphone 600 and loudspeaker
Mutually isolated between 300, the noise reduction microphone that the noise reduction microphone 600 is also used as earphone is used, i.e., when user is listening to
When music or the environment needed peace and quiet, the noise reduction microphone noise reduction can be used, provides the user with what a clear nothing was made an uproar
Music or quiet environment.Specifically, noise reduction microphone 600 is received after environmental noise, by noise reduction module by environmental noise
Manage as anti-phase signal, then broadcasted by loudspeaker, so as to be offset with the environmental noise in air.Noise reduction microphone 600 and loudspeaker
It is mutually isolated between 300, it is mainly used in the music information for avoiding noise reduction microphone 600 from receiving loudspeaker 300, so as to avoid
Music signal is treated as after broadcasting by loudspeaker after inversion signal canceling each other out with the music in air.
In the present embodiment, it is preferred that division board 700 is provided between noise reduction microphone 600 and loudspeaker 300, so as to
The music signal for avoiding loudspeaker from broadcasting is received by noise reduction microphone 600.
In the present embodiment, noise reduction microphone 600 has two effects：When user is in voice-enabled chat, noise reduction microphone 600 can
It is clear without the voice made an uproar to receive user, provide a clear noiseless voice to recipient.When user is receiving voice
Or when appreciating music, the environmental noise received is processed as inversion signal by noise reduction microphone 600, and is broadcasted by loudspeaker, from
And offset the environmental noise in air.
In the present embodiment, further, loudspeaker 300 are located at the one end of housing 100, and main microphon 500 is another located at housing 100
End, noise reduction microphone 600 is on the housing 100 between loudspeaker 300 and main microphon 500.Therefore, when user wears earphone
When, loudspeaker 300 are just relative with duct, and main microphon 500 is just close to source of sound (face of user).
Another embodiment provides a kind of earphone, and the housing 100 of the earphone includes the first housing 101 being detachably connected and the
Two housings 102, the first housing 101 the first sound chamber 200 of formation, noise reduction microphone 600 is on the first housing 101, main microphon
500 on the second housing 102.
Further, the first housing 101 is provided with plug 1011, and the second housing 102 is provided with the slot for housing plug
1021.When the first housing 101 and the second housing 102 patch cooperation, noise reduction microphone 600 and the line of main microphon 500
Extended line can be just in alignment with source of sound (face of user).
The earphone that the present embodiment is provided, by being arranged on for being used to receive for the noise reduction microphone for receiving environmental noise
On the extended line of line between the main microphon and source of sound of sound source signal (i.e. for receive environmental noise noise reduction microphone,
For receive sound source signal main microphon and source of sound three line it is in alignment), so as to form the wheat with directive property
Gram disturbance beam, it is only more sensitive to the sound from source of sound such as face direction, therefore environmental noise can be eliminated significantly, to recipient
One clear noiseless voice is provided.Simultaneously as mutually isolated between noise reduction microphone and loudspeaker, the noise reduction microphone is also
It can use, i.e., when user is in the environment listened to music or needed peace and quiet, can make as the noise reduction microphone of earphone
With the noise reduction microphone noise reduction.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope of this specification record is all considered to be.
Embodiment described above only expresses several embodiments of the present utility model, and it describes more specific and detailed,
But therefore it can not be interpreted as the limitation to utility model patent scope.It should be pointed out that for the common skill of this area
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
Protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
