Embodiment Construction

[0049] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

[0050] The piezoelectric effect of piezoelectric ceramics is usually used in the touch panel to simulate the pressing and bouncing feel of physical buttons. When the user presses the touchpad, the piezoelectric ceramic is deformed, and a current signal is generated based on the positive piezoelectric effect of the piezoelectric ceramic, and the user's pressing force is detected based on the current signal; after the pressure is detected, the control unit sends the piezoelectric ceramic The output signal is based on the inverse piezoelectric effect of the piezoelectric ceramic, which causes the piezoelectric ceramic to generate an electric field in its polarization direction, and then produces mechanical deformation to achieve a vibration effect.

[0051] Here, the positive piezoelectric effect and the negative piezoelectric effect ...

Abstract

The invention provides a touchpad and electronic equipment. The touchpad and the electronic equipment have excellent touch feedback performance. The touchpad comprises a piezoelectric ceramic assembly which is used for detecting pressure and outputting vibration corresponding to the pressure, and the piezoelectric ceramic assembly comprises a piezoelectric ceramic array; and a substrate which comprises a plurality of fixing areas and flexible areas located between the adjacent fixing areas, the plurality of fixing areas are respectively used for arranging a plurality of piezoelectric ceramics in the piezoelectric ceramic array, and the flexible areas are used for connecting the adjacent fixing areas, so that the plurality of piezoelectric ceramics are jointly fixed on the substrate, and are used for absorbing vibration interference between the piezoelectric ceramics on the adjacent fixed areas.

Description

technical field [0001] The embodiments of the present application relate to the field of touch control, and more specifically, relate to a touch panel and an electronic device. Background technique [0002] The touchpad senses the position and movement of the user's finger through the touch sensor, and controls the movement of the pointer on the display interface. The traditional touchpad detects the user's pressing action through physical buttons, and performs functions such as confirmation or calling up a menu. However, the user's pressing action can only be performed on the area below 1 / 2 of the touchpad, and the pressing action cannot be performed on any area of ​​the entire panel. [0003] The pressure touchpad replaces physical pressing with tactile feedback to realize operations such as confirmation and calling up menus, which solves the problem that traditional touchpads can only be pressed partially. The pressure touchpad can adjust the response to the user's pres...
