Embodiment:
Now careful with regard to the composition of the utility model bluetooth hand-free transmission system and the effect that is produced thereof, conjunction with figs. is lifted a preferred embodiment and is described in detail as follows.
Head sees also Fig. 1, and bluetooth hand-free transmitting device 2 of the present utility model is to be configured between bluetooth mobile phone 1 and the automobile audio 5.
Please cooperate Fig. 2, this bluetooth hand-free transmitting device 2 comprises:
Central authorities' microprocessing unit 27 carries out the processing of every data;
Push-button unit 28, the user can use and control arbitrarily or switch;
Amplifying unit 29 can amplify with regard to the source of sound signal, and it can utilize headset plug 33 to cooperate earphone 331 to use, to play sound;
Bluetooth transmission unit 30 can be reached and 1 binding of bluetooth mobile phone by antenna 301, and it disposes microphone 34 in addition;
Switch unit 31, it is connected to an external sound source 35, and has the switching effect;
Electric wave transmission unit 32 can transmit such as FM radio modulation frequency with automobile audio 5 utilizations by antenna 321.
When the utility model bluetooth hand-free transmitting device 2 is installed on the car, only needs that power supply is imported 21 ends and be plugged to easily that cigar lighter gets final product in the car, do not need other complicated distribution.Before the use, the driver needs earlier bluetooth hand-free transmitting device 2 and automobile audio 5 to be carried out just adjusting consistent with respect to the broadcast receiver frequency of automobile audio 5 frequency of electric wave transmission unit 32 to frequently.When the mobile phone calling, this bluetooth mobile phone 1 can see through Bluetooth transmission unit 30 and reach binding with bluetooth hand-free transmitting device 2, this calling sound can be by the frequency emission of electric wave transmission unit 32 simultaneously, after the broadcast receiver frequency of automobile audio 5 receives, loudspeaker by automobile audio 5 are play, to obtain the hand-free purpose.If caller ID or out of Memory are arranged, to deliver to digitlization subcarrier (RDS) coding unit 7 frequency emission by central microprocessing unit 27 by electric wave transmission unit 32, after the broadcast receiver of automobile audio 5 receives, by the screen display of automobile audio 5, so that the end user reads information.If on when conversation car other passenger is arranged, and do not desire to play the calling sound, when possessing privacy, can see through push-button unit 28 to operate fast, and answer with original earphone or phone with automobile audio 5.
