A Speech Signal Transmission System and Method Based on Ultrasound

A voice signal transmission system based on ultrasonic wave includes an ultrasonic modulator (104), a beam forming controller (101), an array of ultrasonic transducers (103) and a user detector (102), in which an ultrasonic modulator (104) is used to modulate the voice signal in the ultrasonic frequency band and output the modulated voice signal to the beam forming controller (101) and a user detector (102). The beam forming controller (101) is used to control the phase and amplitude of the modulated speech signal according to the detection result of the user detector (102), to obtain the electric signal directed to the user, and to output the electric signal directed to the user to the ultrasonic transducer array (103); the beam forming controller (101) is used to control the phase and amplitude of the modulated speech signal according to the detection result of the user detector (102). The electric signal output by the beam forming controller (101) is converted into the ultrasonic signal of the beam pointing to the user, and the ultrasonic signal is transmitted. The scheme mentioned above can improve the convenience of user calls.
