Abstract

The present disclosure relates to a terminal, a touch recognition method, device and electronic equipment. The terminal includes: an ultrasonic transmitter, an ultrasonic signal channel, and a microphone, the ultrasonic transmitter is arranged inside the terminal, and a first perforation is provided on the frame of the terminal for accommodating the microphone; wherein, the ultrasonic transmitter The ultrasonic signal emitted by the transmitter is derived from the interior of the terminal to the surface of the terminal through the ultrasonic signal channel, and the microphone collects the ultrasonic echo signal of the ultrasonic signal, and determines the Whether the terminal is touched. The disclosed technical solution can prevent the ultrasonic transmitter from occupying the space of the glass cover, and ensure that the appearance design of the terminal is more aesthetically pleasing.

Description

technical field [0001] The present disclosure relates to the field of electronic technology, and in particular, to a touch recognition method, device and electronic equipment. Background technique [0002] In related technologies, the anti-mistouch function of smart phones usually requires a proximity sensor. The proximity sensor includes an infrared light diode and a photosensitive diode. During the specific anti-mistouch process, the infrared light wave emits infrared light waves. When it hits the user's face or hair, it will be reflected to the photodiode. The photodiode converts the light wave signal into an electrical signal, and then converts it into a digital signal through a photodiode amplifier (Photo Diode Amplifier). Based on the digital signal, it can identify whether it is in the handheld mode Make a call, and then determine whether to turn on or off the display screen of the smart phone, so as to prevent false touches. Since the integrated circuits (IC) of the...
