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
The present invention relates to technical field of piezoelectricity, particularly a kind of New-type piezoelectric vibration module.
Background technology
Simple tactile feedback applies the several years in mobile phone, and it is for creating quiet prompting, or by providing limited haptic feedback during next button on screen.Novel " high definition " haptic feedback display can allow touch screen have the sense of touch of textured surface, and smooth plane even can be allowed to have embossment to occur.By sense of touch interface, user can not only see the object on screen, can also touch and manipulate them, produces more real feeling of immersion.At present, the vibration machine for generation of vibration has been installed, as making quiet prompt facility in portable set.Currently generally use rotor motor and linear motor, but both there is haptic feedback and vibration sense shortcoming not clearly.Chinese patent 201210261797.1 discloses a kind of piezo vibration module.Described piezo vibration module provides the haptic feedback than described rotor motor and linear motor more " high definition ".
Piezoelectric vibrating device disclosed in patent 201210261797.1, adopts two ends to fix, the middle mode connecting coasting body.Described piezoelectric vibrating device span is comparatively large, result in vibrational energy consumption at itself; Meanwhile, more easily there is fatigue fracture in piezoelectrics; In addition, larger length is also unfavorable for the miniaturization of portable set.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind ofly has the New-type piezoelectric vibration module that large vibratory output, structure are simple, have longer life.
The present invention in order to the technical scheme solving its technical problem and adopt is: a kind of New-type piezoelectric vibration module, comprise base plate, oscillator, support, mass and shell, middle part and the base plate of described oscillator are fixed, the two ends of described oscillator freely, present assembly structure, described support comprises left socle and right support, described left socle and right support are separately fixed at the two ends of oscillator, described mass is fixed on support, and and keep interval between oscillator, described shell is fixed on base plate, and oscillator, support, mass are contained in described enclosure.
As a further improvement on the present invention, the angle formed between described support and described oscillator is 0 to 180 to spend.
As a further improvement on the present invention, described oscillator is made up of upper piezoelectrics, lower piezoelectric body and substrate, and described substrate is fixed between piezoelectrics and lower piezoelectric body; Or described oscillator by one side piezoelectrics fit in substrate above or form below.
As a further improvement on the present invention, be provided with a fixed block between the centre of described oscillator and base plate, described oscillator is fixed on base plate by fixed block interval.
