Embodiment Construction

[0094] The technical solution in this application will be described below with reference to the accompanying drawings.

[0095] The embodiment of the present application relates to touch button components and devices, which can be applied to electronic devices, and the electronic devices can be terminal devices, and the above-mentioned terminal devices can include mobile terminals (such as smart phones or tablet computers), wearable electronic devices (such as smart watches, etc.) , home appliances, car dashboards and other electrical products.

[0096] The application of touch button components is of great significance for improving user experience and waterproofing. However, touch button components are easily mistriggered, which will bring a poor user experience, thereby limiting the technology of touch button components. Development on electronic devices such as smartphones and tablets. In addition, good force perception can enable users to have a good experience of trigge...

Abstract

The invention provides a touch press key assembly, a control circuit and an electronic device, by which the circuit can be simplified, and the cost can be reduced. The electronic device comprises a sensor and a control circuit, the control circuit is used for outputting a driving signal Sd to a first port of the sensor in a first time interval and outputting a high-resistance state or a floating state in a second time interval, and the driving signal Sd is used for driving the sensor to drive a shell to vibrate; the sensor is used for detecting the vibration of the shell and outputting a vibration induction signal Sz through the first port, and the vibration induction signal Sz is a vibration tail wave response signal after the sensor receives the driving signal Sd; the control circuit isfurther used for detecting the vibration induction signal Sz in the second time interval and determining whether to trigger an event or not according to the vibration induction signal Sz.

Description

technical field [0001] The present application relates to the field of electronic products, in particular to a touch button assembly, a control circuit and electronic equipment. Background technique [0002] With the development of mobile device technology, integration will become a trend, which has great advantages in waterproof and user experience. As an obstacle to the integration of mobile devices, physical buttons will gradually be replaced by virtual buttons. However, there are still many problems to be solved in the virtual button, for example, the virtual button is easy to be accidentally triggered by the user, and the cost of industrial mass production equipment needs to be considered. How to realize low-cost virtual keys is an urgent problem to be solved in the industry Contents of the invention [0003] The present application provides a touch button assembly, a control circuit and electronic equipment, which can simplify the circuit and reduce the cost.
