Problems solved by technology

However, touch panels used in large electronic devices such as home appliances often have a large size, and cannot achieve vibration feedback through a small gyro vibration structure like a small electronic device (such as a mobile phone). If a large gyro vibration structure is used, the power will be increased. consumes or takes up space, and cannot achieve accurate touch feedback in a small area

Abstract

The invention provides a touch device. The touch device comprises a touch panel, an addressing structure, a vibration structure and a control center, wherein the touch panel comprises a touch surface, the touch point between a user and the touch surface during operation is defined as a contact, the addressing structure and the vibration structure are arranged at the side, away from the touch surface, of the touch panel, the addressing structure comprises multiple ultrasonic transmitting units and ultrasonic receiving units which are distributed in a scattered mode, and the vibration structure comprises multiple vibration starting units which are distributed in a scattered mode; the ultrasonic transmitting units emit ultrasonic waves, and the ultrasonic receiving units receive the ultrasonic waves and generate electric signals; and the control center judges the position of the contact according to changes of the electric signals fed back by the ultrasonic waves, and vibration starting time of the vibration starting units is adjusted according to the position of the contact so that the contact can generate vibration feedback. The invention furthermore provides a touch feedback driving method for the touch device and an electronic device provided with the touch device.

Description

technical field [0001] The invention relates to a touch device, an electronic device using the touch device and a touch feedback driving method suitable for the touch device. Background technique [0002] Touch is the most important way of human perception and the most natural way for people to interact with machines. Touch devices have been widely used in many fields such as personal computers, smart phones, public information, smart home appliances, and industrial control. In the current touch field, there are mainly resistive touch devices, photoelectric touch devices, acoustic wave touch devices, planar capacitive touch devices, and projected capacitive touch devices. [0003] The sonic touch device is a new type of human-computer interaction. In the current sonic touch technology, the sonic generator can send a high-frequency sound wave and reach the surface of the cover. When the finger touches the cover, the contact point The sound wave is reflected, and the propaga...
