Title:
TOUCH DETECTION AND FEEDBACK SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/001236
Kind Code:
A1
Abstract:
The present application discloses a touch detection and feedback system and method. The touch detection and feedback system comprises a housing, an ultrasonic transmitting end, an ultrasonic receiving end, a feedback output element, and a main control unit, a mounting cavity is provided in the housing, and the mounting cavity is a closed space; the ultrasonic transmitting end, the ultrasonic receiving end, and the feedback output element are all provided in the mounting cavity; the ultrasonic transmitting end, the ultrasonic receiving end, and the feedback output element are electrically connected to the main control unit, separately. The present application solves the problem of touch by mistake of a capacitive key and reduces the risk of reduced sensitivity or even failure of a piezoelectric key caused by a deformation factor, achieves identification of various touch operations such as no touch, light touch, and pressing, can achieve output of multiple levels of feedback signal for different touch forces, and reduces the influence of a vibration feedback element on a touch detection element by a method that touch detection and vibration feedback are not performed at the same time.
