Embodiment Construction

[0051] The embodiment of the present application provides a button structure, which may be a power button and a volume button installed on a terminal. In related technologies, most of these button structures are mechanical buttons installed on the middle frame of a terminal, for example, The key structure is installed in the key installation hole. But there are at least the following problems in this button structure:

[0052] First, the gap between the button structure and the button installation hole can easily allow water and dust to enter the interior of the terminal, affecting the use of the terminal and further reducing the service life of the terminal.

[0053] Second, the user frequently presses the key structure, which easily causes the key structure to loosen in the key mounting hole, and the loose key structure is easily stuck in the key mounting hole, causing the key to be stuck and causing the function of the key structure to fail.

[0054] Third, the above-menti...

Abstract

The embodiment of the invention discloses a key structure of a terminal and the terminal, and belongs to the technical field of terminals. The key structure comprises one or more pressure sensors, anultrasonic sensor, one or more deformation parts, a control part and a flexible circuit board, wherein the one or more pressure sensors, the ultrasonic sensor, the one or more deformation parts and the control part are all fixed on the flexible circuit board; the ultrasonic sensor is used for transmitting mechanical waves, receiving echoes reflected by the outer surface of a middle frame of the terminal or the outer surface of a display screen panel, and sending echo signals generated based on the echoes to the control component; and the control part is used for generating operation information based on the received pressure signal and echo signal, and sending the operation information to a processor of the terminal, so that the processor executes operation processing based on the operation information. According to the invention, the service life of the terminal can be prolonged.

Description

technical field [0001] The present application relates to the technical field of terminals, in particular to a key structure of a terminal and the terminal. Background technique [0002] With the rapid development of terminal technologies, terminals such as mobile phones and tablet computers have become indispensable communication tools in people's lives. [0003] In the related art, the middle frame of the terminal is usually provided with a button installation hole, and the button structure (such as a power button, a volume button, etc.) can be installed in the button installation hole, and, in order to enable the button structure Correspondingly, there is a certain gap between the button structure and the button installation hole, so that the user can realize the corresponding function by pressing the button structure. [0004] In the process of implementing the present application, the inventors found that the related technology has at least the following problems: [...
