Abstract

The invention discloses a signal sensor, comprising a user input end, a force conversion unit, a first piezoelectric and a signal outlet unit, wherein the user input end is used for a user to slide thereon; the force conversion unit is used for converting a thrust when a user slides on the user input end into a pressure acting on the first piezoelectric; the first piezoelectric is used for generating stressed deformation in response to the pressure acting thereon, and causing the surface thereof to be charged; and the signal output unit is used for outputting the charge on the surface of the first piezoelectric as a sensing signal. The invention further discloses a signal sensing method and portable electronic equipment. By applying the signal sensor, an electric sensing signal is generated directly, and the signal sensor can be directly used for controlling various specific applications of the equipment with no need of interference from other equipment processors, so the signal sensor is extremely suitable for various portable electronic equipment; furthermore, the signal sensor saves cost, avoids the defect of erroneous output owing to the random motion of the user without interaction purpose, and achieves wider applicable scope.

Description

technical field [0001] The invention relates to the field of sensing technology, and more specifically, to a signal sensor, a sensing method and a portable electronic device. Background technique [0002] In the consumer electronics market, there is a clear and strong need for products that can be controlled by simple user interactions. To achieve this goal, more and more input devices are being developed that provide control signals for different functions. One area of ​​input devices that is not perfect is the swipe sensor. This kind of sensor senses the operation of scratching or sliding on the surface of the device (such as mobile phone, MP3 player, etc.) to perform various specific applications (such as controlling the volume of the speaker, etc.). For this application, touch screens can be implemented using the working principle of capacitive touch sensors. [0003] Existing swipe sensor technologies for non-screen applications mainly use vibration and sound detectio...
