Problems solved by technology

[0002] In the related art, due to the limitation of the structure of the intelligent terminal with the ultrasonic anti-mis-touch function, the directionality of the ultrasonic signal transmitted by the terminal and the directionality of the received ultrasonic echo signal are relatively poor, so that when the user talks in the handheld mode, even if the When the smart terminal is close to the smart terminal, the smart terminal may also receive a relatively high-energy ultrasonic echo signal, thereby turning off the display to realize the anti-mistouch function, resulting in turning off the touch screen when it is not necessary to turn off the touch screen, and the user experience is better.

Abstract

The invention relates to a terminal protecting shell, a touch identification method and a touch identification device. The terminal protecting shell comprises an ultrasonic signal sheltering plate and an ultrasonic echo signal through hole, wherein the ultrasonic signal sheltering plate is arranged above the position, corresponding to the surface position of transmitting an ultrasonic signal by the terminal, of a terminal protecting shell; the first end of the ultrasonic echo signal through hole is arranged at the position, corresponding to a microphone perforation in the surface of the terminal, of the terminal protecting shell; the second end of the ultrasonic echo signal through hole is arranged at the position, corresponding to the preset position on the front side of the terminal, of the terminal protecting shell; the ultrasonic signal sheltering plate resists the ultrasonic signal transmitted by the terminal from being transmitted to the preset direction; and the ultrasonic echo signal of the ultrasonic signal is guided into the microphone of the terminal through the ultrasonic echo signal through hole of the terminal protecting shell. According to the technical scheme of the invention, the directivity of the ultrasonic signal transmitted by the terminal and the directivity of the ultrasonic echo signal received by the terminal are enhanced.

Description

technical field [0001] The present disclosure relates to the field of electronic technology, and in particular to a terminal protection case, a touch recognition method and a device. Background technique [0002] In the related art, due to the limitation of the structure of the intelligent terminal with the ultrasonic anti-mis-touch function, the directionality of the ultrasonic signal transmitted by the terminal and the directionality of the received ultrasonic echo signal are relatively poor, so that when the user talks in the handheld mode, even if the When the smart terminal is close to the smart terminal, the smart terminal may also receive a relatively high-energy ultrasonic echo signal, thereby turning off the display to realize the anti-mistouch function, resulting in turning off the touch screen when it is not necessary to turn off the touch screen, and the user experience is better.
