Abstract

The present application provides a button, a control circuit and an electronic device. The key includes a key cap, a base, a cantilever beam and a piezoelectric device; the key cap is installed on the base, the base has a cavity, the cantilever beam has elasticity, one end of the cantilever beam is fixed on the base, and the other end of the cantilever beam extends into the container The piezoelectric device is installed on the cantilever beam, and the piezoelectric device is used for detecting the deformation of the cantilever beam and for driving the cantilever beam to vibrate so that the other end of the cantilever beam elastically touches the keycap. The button provided by the present application, by supporting an elastic cantilever beam on the base, arranging a piezoelectric device on the cantilever beam, and detecting the deformation of the cantilever beam through the piezoelectric device and driving the cantilever beam to vibrate, so as to realize pressing detection and tactile feedback, There is no need to separately set the detection unit and the actuation unit, which simplifies the structure.

Description

technical field [0001] The present application belongs to the field of electronic products, and more specifically, relates to a button, a control circuit and an electronic device. Background technique [0002] Buttons are commonly used human-computer interaction devices in electronic products. Buttons are divided into passive tactile buttons and active tactile buttons. Passive feedback buttons provide tactile feedback through the restoring force of elastic structures such as button springs. A button generally includes a button unit, an electrical actuation unit and a detection unit. The detection unit detects the pressing action of the button, and then the internal or external controller controls the electrical actuation unit to vibrate the button to achieve active tactile feedback. The key structure is complex, and the electrical actuation unit and the detection unit often influence each other. SUMMARY OF THE INVENTION [0003] The purpose of the embodiments of the pre...
