Title:
ULTRASONIC CONTROL METHOD, APPARATUS AND DEVICE, AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/179297
Kind Code:
A1
Abstract:
Provided are an ultrasonic control method, apparatus and device, and a storage medium. Said method comprises: in the process of transmitting an ultrasonic driving signal, acquiring driving sound wave characteristics of the ultrasonic driving signal (S10); determining suppressing sound wave characteristics of an inverted suppressing signal according to the driving sound wave characteristics (S20); and when the transmission of the ultrasonic driving signal ends, applying the inverted suppressing signal to an ultrasonic sensor according to the suppressing sound wave characteristics, so as to suppress the resonance generated by the ultrasonic driving signal by means of the inverted suppressing signal (S30).
