Abstract
The utility model relates to a hand-free device for a wireless microphone of mobile telephones, which is composed of a microphone which is connected with a wireless emitter, a wireless receiver, and a loudspeaker. The output of the device is connected with an earphone jack of the mobile telephone or an adapter. The receiver is integrated with the loudspeaker or is internally positioned in the mobile telephone body. The utility model has the advantages of simple structure and easy use. The utility model can not only transfer the call information through the wireless mode, but also is more suitable for the drivers' habitual calling actions without any influence on the drivers' attention on driving at the same time, thus, the driving security is ensured.
Description
The utility model relates to a kind of mobile phone hands-free device, the mobile phone wireless microphone hands-free device that especially a kind of conversation utilizes wireless mode to finish.
At present, mobile phone calling can be finished call function by earphone or vehicle-mounted wired hands-free device.In advancing, be with earphone to speak, not only do not meet the common custom of speaking, and the user always there is uncomfortable sensation; Wired on-vehicle hands-free device, be directly to link to each other by electric wire with the adapter of mobile phone by microphone, because the existence of electric wire, and be subjected to certain restriction, and the position of microphone is general not in speaker's dead ahead, therefore conversation action nature still, and the attentiveness when disperseing driver's driver behavior easily.In addition, also have a kind of mobile phone that carries hand-free function now, its loudspeaker sound is less, in the enforcement of driving, because the environmental noise influence is difficult to not hear dialog context sometimes.
The purpose of this utility model is to provide a kind of mobile phone wireless microphone hands-free device at the deficiency of prior art, and hand-free call is to transmit the call-information that calling party and mobile phone send by wireless mode.
The purpose of this utility model is achieved in that a kind of mobile phone wireless microphone hands-free device, and it connects wireless launcher, wireless receiver and loud speaker by microphone forms, and its output connects mobile phone earphone jack or adapter.
Described loud speaker and receiver can be one.
Described receiver can built-in mobile phone body in.
Described loud speaker can connect power amplification circuit.
Described power amplification circuit is connected to the amplitude modulation potentiometer of power amplifier size.
According to the technique scheme analysis as can be known, the utlity model has characteristics simple in structure, easy to use, it not only can transmit call-information by wireless mode preferably, and more adapt to driver's habitual movement of conversing usually, do not influence simultaneously the attentiveness that the driver drives, guarantee to drive safety.
Below in conjunction with accompanying drawing and specific embodiments the utility model is described in further detail.
Fig. 1 is the utility model formation and microphone and reflector scheme of installation;
Fig. 2 is the utility model receiver and speaker circuit schematic diagram.
Referring to Fig. 1,2, the utility model is a kind of mobile phone wireless microphone hands-free device.Its microphone 1 can be one with wireless launcher 2, and the input signal of the output of wireless receiver 4 and loud speaker 5 power amplifiers is connected with mobile phone 6 adapter mouths (or earphone jack) by cable 7.Microphone 1 can arbitrarily be placed according to driver's custom with wireless launcher 2, for example is directly installed on the steering wheel 3 in dead ahead, also it can be arranged on panel board near.The driver can face when microphone 1 is spoken on the steering wheel, can still watch the place ahead attentively for two, does not influence attentiveness when therefore conversing, but also meets the common custom of speaking.The output of microphone 1 connects wireless launcher 2, and the signal of reflector 2 emissions can be the signal of infrared ray or other wireless transmission.Wireless receiver 4 receives the signal of reflector, and receives the audio frequency input of mobile phone through the amplification conversion of changeing auxiliary circuit triode T1, T2 by mobile phone adapter mouth or earphone jack, and voice signal is passed to mobile phone; In addition, the audio signal of mobile phone output arrives loud speaker 5 by adapter mouth or earphone jack through power amplifier 34119, the output of loud speaker 5 can be according to the different sound equipment of amplitude modulation potentiometer W output that connects between different site environment resonance-amplifiers 34119 pins 4,5, reach requirement, make things convenient for driver's interchange of conversing.
In addition, power amplification circuit 34119 of the present utility model, loud speaker 5 and receiver 4 can be one, place the mobile phone outside.Also receiver of the present utility model can be placed in the mobile phone body, and only loud speaker and amplifier section be placed the outside.
