摘要： An ultrasonic data transmission method, apparatus and system, a terminal device and a medium are provided. The method is applied to a transmitting terminal which includes at least two ultrasonic signal transmitting arrays. The method includes: a single-frequency ultrasonic coding signal of to-be-transmitted information corresponding to each ultrasonic signal transmitting array is respectively determined, ultrasonic codes of to-be-transmitted information corresponding to different ultrasonic signal transmitting arrays being different; and corresponding at least two single-frequency ultrasonic code signals are transmitted through the at least two ultrasonic signal transmitting arrays to a receiving terminal in a focusing mode, frequency bands of transmitting frequencies of different ultrasonic signal transmitting arrays being different.
