Description

There is the sonifer of active noise reduction

Technical field

This utility model relates to field of hearing aids, particularly to a kind of sonifer with active noise reduction.

Background technology

Sonifer is that the one person that contributes to hearing loss improves dysacousis, and then improves and his conference communicative competence Equipment.Sonifer is generally divided into boxlike, worm behind ear and inner ear type, and wherein, boxlike and post-aural hearing aid are due to low price quilt A large amount of uses, but existing boxlike and post-aural hearing aid generally comprise an earphone portion and a body, and camouflage property is poor, it is easy to Just it is seen to be sonifer, and because of sense of personal worth, user is usually reluctant that allowing others know oneself is a dysaudia personage, and One earphone portion only one of which mike, it is impossible to well extraneous noise removal is fallen, noise jamming is big, and using effect is poor, The requirement that user is the highest cannot be met.

Summary of the invention

The purpose of this utility model is to provide one to be more easy to be accepted for solving the problems referred to above, has again actively fall Make an uproar function, reduce noise jamming, excellent noise reduction effect, it is easy to accomplish the sonifer with active noise reduction.

To this end, the utility model discloses a kind of sonifer with active noise reduction, including two earphone portions and a body, institute The two earphone portions that state all include earphone case and the first receiver being arranged in this earphone case, the second receiver, the first wheat Gram wind and second microphone, described first mike penetrates earphone case for receiving external sound, and described second microphone sets Put on the first receiver side, for receiving the external sound after the reverse noise cancellation that the first receiver plays, described the Two receivers are for ear internal broadcasting sound, and described body includes noise reduction process module, audio processing modules, power management Module and power module, described noise reduction process module is connected with the first mike and the first receiver respectively, described Audio Processing Module is connected with second microphone and the second receiver respectively, and described power module is noise reduction process mould by power management module Block and audio processing modules are powered.

Further, described power module is rechargeable battery.

Further, described body also includes that USB interface and charge management circuit, described USB interface pass through charging valve Reason circuit is connected with rechargeable battery.

Further, described body is additionally provided with volume knob, and described volume knob is with audio processing modules even Connect.

Further, described first receiver is moving-coil receiver, and described second receiver is moving-iron receiver.

Further, described audio processing modules is DSP audio digital processing device.

Further, described two earphone portion are not electrically connected with body by strong plasticity cable.

Advantageous Effects of the present utility model:

This utility model is worn comfortable with easy to use, and disguise oneself as earphone, is more easy to be accepted, and has again active noise reduction merit Can, reduce noise jamming, excellent noise reduction effect, and be easily achieved.

Accompanying drawing explanation

Fig. 1 is the structure chart of this utility model embodiment；

Fig. 2 is the electrical connection block diagram of this utility model embodiment.

Detailed description of the invention

In conjunction with the drawings and specific embodiments, this utility model is further illustrated.

As depicted in figs. 1 and 2, a kind of sonifer with active noise reduction, including two earphone portion 1 and bodies 2, described two Earphone portion 1 all include earphone case 11 and first receiver the 14, second receiver 15 being arranged in this earphone case 11, One mike 12 and second microphone 13, described first mike 12 penetrates earphone case 11 for receiving external sound, specifically , earphone case 11 is provided with a through hole, and the first mike 12 extend out to earphone case 11 surface outside receiving through through hole Boundary's sound, described second microphone 13 is arranged on the first receiver 14 side, for receive through first receiver 14 play anti- External sound after feedback noise cancellation, concrete, the first mike 12 is arranged on before the first receiver 14, is both placed on Being positioned in the cavity outside ear in earphone case 11, described second receiver 15 is positioned at ear in being arranged on earphone case 11 Position, for playing sound to ear is internal, in this specific embodiment, the first mike 12 and second microphone 13 are silicon wheat Gram wind, the first receiver 14 is moving-coil receiver, and the second receiver 15 is moving-iron receiver.Described body 2 includes noise reduction process Module 27, audio processing modules 26, power management module 21 and power module 22, described noise reduction process module 27 is respectively with first Mike 12 and the first receiver 14 connect, described audio processing modules 26 respectively with second microphone 13 and the second receiver 15 Connecting, described power module 22 is powered for noise reduction process module 27 and audio processing modules 26 by power management module 21.This In specific embodiment, power module 22 is rechargeable battery, specially lithium battery, and audio processing modules 26 is DSP digital audio Processor.

Concrete, in the present embodiment, body 2 also includes USB interface 24 and charge management circuit 23, described USB interface 24 It is connected with lithium battery 22 by charge management circuit 23.Extraneous power supply is plugged in USB interface 24 by USB data line, through filling Fulgurite reason circuit 23 charges for lithium battery 22.

Further, described body 2 is additionally provided with volume knob 25, described volume knob 25 and Audio Processing mould Block 26 connects, and is used for regulating volume.

Further, in the present embodiment, two earphone portions 1 are electrically connected with body 2 by strong plasticity cable 3 respectively, use Strong plasticity cable 3 is flexible, stretchable and can maintain flexural deformation, and can make the shape of tack, easy to use, wears easypro Suitable.

Work process: the first mike 12 receives external sound, is transferred to noise reduction process module 27, noise reduction process module 27 After processing, output noise reverse signal gives the first receiver 14, and the first receiver 14 plays reverse noise, at earphone case In cavity in 11, after the noise contained in external sound is reversed noise cancellation, is received by second microphone 13, and be transferred to Audio processing modules 26, after it is processed and amplify by audio processing modules 26, is transferred to the second receiver and plays out, To amplifying and the sound of low noise, it is achieved noise reduction hearing-aid function.
