Abstract

The invention relates to an electronic device comprising a display screen. An ultrasonic module is arranged in that display screen, and the electronic device further comprises a control unit. Each structure located above the ultrasonic module in the display screen can conduct ultrasonic wave. The top surface of the ultrasonic module faces the surface of the display screen for displaying an image,and the ultrasonic module is used for emitting ultrasonic waves and receiving ultrasonic waves reflected from a target under the control of the control unit, and converting the reflected ultrasonic waves into electrical signals. The control unit is used for judging that when the strength of the electric signal is greater than a set threshold value, a target is considered to be close to the electronic device. The electronic device uses ultrasonic wave to detect whether a target is close to the electronic device. Because the ultrasonic wave has the ability to penetrate the material, the short-range sensing function can be realized without opening holes in the electronic device, thereby improving the waterproofing performance of the electronic device.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to an electronic device. Background technique [0002] Traditional electronic devices are usually equipped with proximity sensors. Taking a mobile phone as an example, the proximity sensor is usually located in the upper left corner or upper right corner of the mobile phone. The proximity sensor can determine that the mobile phone is close to the person's face or clothes and turn off the touch function of the screen, so as to prevent misoperation. [0003] However, since the traditional proximity sensor needs to use infrared rays to detect whether an object is close to the electronic device, holes need to be made on the electronic device to allow the infrared rays to penetrate the screen, thereby reducing the waterproof performance of the electronic device. SUMMARY OF THE INVENTION [0004] Based on this, it is necessary to provide an electronic device to solve the pr...
