Embodiment:
In the theory diagram shown in Figure 1, the outer sound-pickup device of automobile car is made up of external trigger 1, amplifying unit 2, sound processing unit 3, voice output unit 4 and power supply 5.
Operation principle is as follows: at first, after amplifying unit 2 will carry out preposition amplification by the outer sound of the car that external trigger 1 is picked up, carry out the signal transmission again, transmit signals to sound processing unit 3 and carry out aftertreatment, provide to be fit to the signal that voice output unit 4 uses, last is that voice signal uses for the driver by voice output unit 4 with the signal transition that receives.Power supply 5 can adopt the direct current 12V that automobile storage battery is provided to carry out the direct current 5V that exports after the DC/DC conversion.
According to the concrete communication mode of sound processing unit 3 and sound output unit 4, three specific embodiments of the present utility model are described respectively below:
Embodiment 1: sound processing unit 3 is made up of PCM encoder 6 and bluetooth module 7 in the present embodiment, and voice output unit 4 is made up of bluetooth earphone 8.At first, the outer sound of the car that external trigger 1 is picked up is after amplifying unit 2 carries out preposition amplification, be sent to PCM encoder 6 and carry out the speech coding processing, after PCM encoder 6 changes analogue voice signal into digital voice signal, send into the PCM port of bluetooth module 7, carry out wireless transmission by bluetooth module 7, carry out wireless receiving by bluetooth earphone 8 at last, and decoding is reduced into voice signal and uses for the driver.Bluetooth earphone 8 adopts the powered battery that carries.
Embodiment 2: sound processing unit 3 is made up of infrared transmitter 9 in the present embodiment, and voice output unit 4 is made up of infrared earphone 10.At first, the outer sound of the car that external trigger 1 is picked up is after amplifying unit 2 carries out preposition amplification, be sent to infrared transmitter 9 and carry out carrier modulation and emission, carry out wireless receiving by infrared earphone 10 at last, the infrared signal demodulation after the modulation is reduced to voice signal uses for the driver.Infrared earphone 10 adopts the powered battery that carries.
