Description
Technical field
The utility model relates to the device that a kind of application is picked up sounding and listened system for electrical teaching, the hands-free receiver of particularly a kind of mobile phone.
Background technology
Mobile phone of the prior art will realize that hand-free function is generally by following approach: mobile phone inside is provided with special earphone jack, adopts headset one end of mobile phone special use to insert in this jack, and the other end is placed in the auricle.The headset that is placed in the auricle has radiation effects, the health of entail dangers to human body; Simultaneously not that any mobile phone all possesses earphone jack and headset are arranged, so the part mobile phone can't be realized hand-free function.
Invention constitutes
The purpose of this utility model is to overcome weak point of the prior art and provides a kind of radiationless, the hands-free receiver of universal mobile phone.
The purpose of this utility model realizes by following approach:
The hands-free receiver of mobile phone comprises signal pickup device and loud speaker, and its structural feature is, signal pickup device is a kind of microphone, and microphone is electrically connected with loud speaker, also comprises a kind of connector, microphone is attached on the mobile phone sound hole, and carries out dismantled and assembled the connection by connector with mobile phone.
When mobile phone is connected, microphone receives the voice messaging that sends on the mobile phone sound hole and by loud speaker this voice messaging is propagated in the space, can reach hands-free receiving function.Owing to be directly to pick up voice signal from the mobile phone sound hole, like this, microphone need not anyly to design and be designed to universal architecture targetedly especially with being connected, and can be connected with any a mobile phone, and picks up voice signal from this mobile phone sound hole.Like this, the utility model is applicable to any a mobile phone, and need not dispose headset and jack thereof separately, simultaneously need not be because of too close mobile phone or headset raying pollution, not entail dangers to health.
The utility model can also further be specially:
Connector is a kind of clamp, and microphone is fixed in a clamping bar end of clamp.
As connector, its structure is enough simple undoubtedly with binding clip, and clamp is a kind of general connector, not only can any a mobile phone of clamping connection, and also the company of tearing open is convenient.
Also comprise a kind of cushion pad, cushion pad is fixed in microphone face, and the folder pad is between microphone and mobile phone.
Cushion pad or be a kind of foam-rubber cushion, or be " Π " shape soft plastic.
Connector just can be clamped mobile phone like this, and the clamping bar end folder that will be connected with microphone is attached on the sound hole of mobile phone, and cushion pad folder pad is between microphone and mobile phone, because of cushion pad radio reception effective, can better receive the effect of mobile phone speech information, also can not press from both sides simultaneously, the surface of scratch mobile phone because of clamp.Simultaneously, cushion pad can also be fixed in another clamping bar end of clamp, plays the effect of protection mobile phone.Foam-rubber cushion is except good buffer effect, and its sound-absorbing effect is also fine; And " Π " shape cushion pad can cover on the mobile phone sound hole with its groove surface, and not only abundant sound-absorbing, and groove side is along also having good buffering effect, and therefore, these two kinds of structures all are suitable as cushion pad very much.
The utility model can also further be specially:
Also include control circuit, it is installed in the inner chamber of connector, and is electrically connected with microphone.
Control circuit includes analog-digital commutator, adapting amplifier device, signal processing apparatus and digiverter, and is electrically connected successively, and wherein analog-digital commutator is electrically connected with microphone, and digiverter is electrically connected with loud speaker.
Also include a power amplifier, it is plugged between signal processing apparatus and the digiverter.
The effect of analog-digital commutator is analog signal conversion is become the digital signal or the signal of telecommunication.Analog-digital commutator converts the voice messaging that mobile phone heard to the signal of telecommunication in the utility model, and is handled by signal processing apparatus; Adapting amplifier device is plugged between analog-digital commutator and the signal processing apparatus, and the digital electric signal after institute's conversion can be carried out the first time and amplify, thus the processing accuracy of raising signal processing apparatus; By power amplification, and send the signal of telecommunication to loudspeaker arrangement, the voice messaging that mobile phone hears is propagated out by loudspeaker arrangement through digiverter.
In sum, the utility model is by a kind of microphone of universal architecture and connector and can be from pickoff signals on the sound hole of any a mobile phone, and be the signal of telecommunication by Simulation Conversion Assembly conversion mobile phone speech analog information, and propagate out through loudspeaker arrangement, thereby realization mobile phone hands-free function, have radiationless side effect and versatility, promptly applicable any a mobile phone.The utility model especially is fit to be applied in the occasion that has than enclosure space, and for example: in indoor, the automobile bodies, like this, the sound that loud speaker sent can more clearly be delivered in cellie's the ear.
