Problems solved by technology

The piezoelectric vibrating device has a relatively large span, which causes the vibration energy to be consumed by itself; at the same time, the piezoelectric body is prone to fatigue fracture; in addition, the large length is not conducive to the miniaturization of portable equipment

Abstract

The invention discloses a novel piezoelectric vibration module. The piezoelectric vibration module is provided with a vibration plate, wherein the vibration plate is in contact with a piezoelectric body in double-sized way, the middle of the vibration plate is fixed on a bottom plate support to form a dual-cantilever structure, the two ends of the vibration plate is connected with the support, an inertia body is connected onto the support, and a shell is fixed at a bottom plate. A base plate does bending vibration under the actions of a voltage applied to the piezoelectric body, and a piezoelectric vibration scheme having high vibration magnitude is provided; two free ends of dual cantilevers are connected to a mass block through the support, and thus, the piezoelectric vibration module is stable in structure; with the mode of the dual cantilevers, large vibration quantity can be provided by a vibrator in a short length; and meanwhile, the probability of fatigue break of the piezoelectric vibration is reduced.

Description

technical field [0001] The invention relates to the field of piezoelectric technology, in particular to a novel piezoelectric vibration module. Background technique [0002] Simple haptic feedback has been used in mobile phones for several years to create silent alerts, or to provide limited contact feedback when pressing a button on the screen. A novel "high-definition" touch feedback display gives touchscreens a textured feel and even embossed smooth surfaces. Through the tactile interface, users can not only see the objects on the screen, but also touch and manipulate them, resulting in a more realistic sense of immersion. Currently, a vibration generator for generating vibration is installed in a portable device for a silent prompting function. Rotor motors and linear motors are commonly used at present, but both have the disadvantage that the contact feedback is not clear enough. Chinese patent 201210261797.1 discloses a piezoelectric vibration module. The piezoelec...
