Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.
Referring to Fig. 1-9, a kind of wear-type pickup noise reduction communication earphone, comprising: the headset body 1 of wear-type interior is located at ear
The electronic component of machine ontology 1, the electronic component includes: pickup Dolby circuit 41, processing chip 42, loudspeaker 44 and power amplifier
43；The principle of its pickup noise reduction is as follows:
S11, the pickup Dolby circuit are acquired the sound outside headset body 1, and the audio signal after acquisition is sent
To processing chip,
S12, processing chip handles audio signal, and audio signal is sent to power amplifier by treated, wherein place
It includes: to handle core when the corresponding sound of voice signal is not less than default decibel threshold that reason chip, which carries out processing to audio signal,
Piece carries out wave crest reduction to the voice signal；By after reduction voice signal and less than default decibel threshold voice signal into
Row mixing.Wherein, the default decibel threshold is 85 decibels.
S13, to treated, audio signal amplifies power amplifier, the audio signal amplified,
S14, loudspeaker play back the corresponding sound of audio signal.The sound acquired in this way by the playback of loudspeaker 44 from the external world,
It can allow except protection user's sense of hearing, it can also be allowed to hear external sound.Such as special policeman, special force, anti-terror assault team
Equal crowds, also can be with teammate's real-time communication while capable of completely cutting off the report of a gun of the extraneous damage sense of hearing on tape after the earphone.
In the present embodiment, further includes: tone frequency channel wire 2 and microphone 3；The bottom of headset body 1 is arranged in the tone frequency channel wire 2,
The microphone 3 is connected with one end of the tone frequency channel wire 2, and the other end of the tone frequency channel wire 2 is connected with PTT communication apparatus.In this way
It can be transferred to the headset socket of the intercom of various models, so that earphone is supported various intercom communications, be suitble to needing to protect
It is accessible in the environment of the sense of hearing to be communicated using intercom.As another preferred embodiment, the tone frequency channel wire 2 is 7.1mm quadrupole sound
Frequency line.
In the present embodiment, the power amplifier 43 has three-level power amplifier multiple.Maximum amplification factor is selected, may be implemented
Under quiet environment, small sound collection is amplified, allows user that can clearly hear the sound that cannot be identified only according to ear.
The smallest amplification factor is selected, may be implemented to cut down high-decibel sound moment, so in the environment of noisy, sudden loud noise
Order recovery is to normal operating conditions afterwards, to protect user's sense of hearing.
In the present embodiment, the headset body 1 includes: earphone outer covering and ear muff；The ear muff includes filler, described to fill out
Object is filled to be sealingly fitted in earphone outer covering.Specifically, the filler is silica gel or sponge, and earphone is made to have physics drop in this way
It makes an uproar function, every the prejudicial sound of absolute hearing.The key for adjusting volume is additionally provided in the headset body 1.
In the present embodiment, the loudspeaker 44 are two, and two loudspeaker 44 are distributed in the two sides of headset body 1, and allow makes in this way
User can more clearly distinguish sound source or so orientation, make up physics noise cancelling headphone to a certain extent after wearing earphone
Cause people that can not listen the defect for arguing position.
The wear-type pickup noise reduction communication earphone of this programme is by the pickup Dolby circuit 41 to the sound outside headset body 1
Sound is acquired, and sends processing chip 42 for the audio signal after acquisition, and processing chip 42 handles audio signal,
And audio signal is sent to power amplifier 43 by treated, to treated, audio signal amplifies power amplifier 43, obtains
To the audio signal of amplification, loudspeaker 44 play back the corresponding sound of audio signal, can be played back in this way by loudspeaker 44 from outer
The sound of boundary's acquisition can protect user's sense of hearing, moreover it is possible to user be allowed to hear in the big volume environment that the sense of hearing may be lost
External sound, realization and the communication between other people.In addition, user can more clearly distinguish sound after wearing earphone
Source or so orientation, making up physics noise cancelling headphone to a certain extent causes people that can not listen the defect for arguing position.It can be by the earphone
It connects, and is distally linked up with communication apparatus such as intercom, mobile phones.
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to protection of the invention
Range.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
