Title:

COMPOSITE STRUCTURE OF PIEZOELECTRIC RECEIVER AND ULTRASONIC WAVE GENERATOR

Document Type and Number:

WIPO Patent Application WO/2016/155321

Kind Code:

A1

Abstract:

Disclosed in the present invention is a composite structure of a piezoelectric receiver and an ultrasonic wave generator, comprising: a piezoelectric chip, an ultrasonic signal generator, an audio signal input circuit and a switching circuit. The input end of the switching circuit is connected with the ultrasonic signal generator and the audio signal input circuit respectively to be switched between the ultrasonic signal generator and the audio signal input circuit. The output end of the switching circuit is connected with the piezoelectric chip. By combining the piezoelectric receiver and the ultrasonic wave generator together, only one piezoelectric chip is required to implement both receiver function and ultrasonic wave generator function, so that the cost and space can be saved, which is the technical effect of the present invention.
