Abstract
The utility model relates to a wireless loudspeaking hand-free device for mobile phones, which is formed by that a microphone is connected with a wireless emitter, a wireless receiver and a loudspeaker, wherein, the microphone is appressed with a sound pick-up device of the mobile phone, and the wireless emitter can also be internally arranged in the body of the mobile phone; the receiver can be integrated with the loudspeaker. The utility model has the advantages of simple structure, convenient operation and wide applicability, and the utility model can better transfer conversation information through a wireless mode to ensure driving safety.
Description
The utility model relates to a kind of vehicular telephone hands-free device, the wireless hands-free device of raising one's voice of the vehicular telephone 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 is directly to link to each other by electric wire with the adapter of vehicular telephone by microphone, because the existence of electric wire, and be subjected to certain restriction, during use, in car, install more loaded down with trivial details.In addition, also have a kind of vehicular telephone 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 vehicular telephone the wireless hands-free device of raising one's voice at the deficiency of prior art, hand-free call is that the sound of the vehicular telephone side of getting still spreads out of by the microphone of vehicular telephone itself by the voice amplification of wireless mode with the vehicular telephone side of throwing into.This device can be suitable at any vehicular telephone, thereby has avoided the structure of present various mobile radio different and need different adaptor unions.
The purpose of this utility model is achieved in that the wireless hands-free device of raising one's voice of a kind of vehicular telephone, it connects wireless launcher, wireless receiver and loud speaker by microphone forms, and its input is to be close to the vehicular telephone acoustic pickup by the microphone that is connected wireless launcher.
Described projector and microphone can be one.
Described microphone can connect power amplification circuit.
But described projector direct connection is on the acoustic pickup of vehicular telephone.
Described projector can built-in vehicular telephone body in.
Described loud speaker and receptor can be one.
Described loud speaker can connect power amplification circuit.
Described power amplification circuit is connected to the amplitude modulation potential device 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, more adapts to various vehicular telephones, exempting various mobile radio needs the trouble of different connector, and installs and simplify.
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 projector, receptor and loud speaker scheme of installation;
Fig. 2 is the utility model receptor and speaker circuit schematic diagram.
Referring to Fig. 1,2, the utility model is the wireless hands-free device of raising one's voice of a kind of vehicular telephone.Its microphone 1 can be one with wireless launcher 2 and vehicular telephone acoustic pickup 6 is close to, and wireless receiver 4 and loud speaker 5 can arbitrarily be placed.Microphone 1 and wireless launcher 2 and vehicular telephone are fixed on left and right the place ahead of steering position.The output of microphone 1 connects wireless launcher 2, and the signal of projector 2 emissions can be the signal of infrared ray or other wireless transmission.Wireless receiver 4 receives the signal of projector, arrive loud speaker 5 through power amplifier 34119, the output of loud speaker 5 can reach requirement according to the different sound equipment of bonded assembly amplitude modulation potential device W output between different site environment regulating amplifiers 34119 pins 4,5, makes things convenient for the chaufeur conversation to exchange.
In addition, power amplification circuit 34119 of the present utility model, loud speaker 5 and receptor 4 can be one, place the vehicular telephone outside.Projector of the present utility model can built-in vehicular telephone body in, and only loud speaker and amplifier section are placed the outside.
