Abstract
An ultrasonic transceiver system and an electronic device. The ultrasonic transceiver system includes a signal generating circuit and an ultrasonic sensor chip. The signal generating circuit is composed of discrete devices and includes a pulse generating circuit and a resonance circuit. The pulse generating circuit receives a control signal output by the ultrasonic sensor chip, and generates, according to the control signal, a first pulse voltage signal and a second pulse voltage signal which are in opposite phase to each other, and the resonant circuit receives the first pulse voltage signal and the second pulse voltage signal which are in opposite phase to each other and generates a drive signal under action of the first pulse voltage signal and the second pulse voltage signal. The ultrasonic sensor chip receives the drive signal and generates an ultrasonic signal according to the drive signal.
