Abstract
The invention discloses a kind of New-type piezoelectric vibration module, the piezo vibration module has the oscillating plate that Double-face adhesive closes piezoelectrics, it is fixed in the middle part of oscillating plate on mount holder and forms assembly structure, the both ends connecting bracket of oscillating plate, coasting body is connected on stent, and it is fixed on the shell of bottom plate, piezoelectrics make substrate bend vibration under the action of outer making alive, provide a kind of piezo vibration module scheme with high vibration magnitude, mass block, stable structure are connected to by stent using two free ends of double cantilever beam；The mode of double cantilever beam enables to oscillator to provide big vibratory output under shorter length, meanwhile, the possibility of reduction piezoelectrics fatigue fracture.
Description
Technical field
The present invention relates to technical field of piezoelectricity, more particularly to a kind of New-type piezoelectric vibration module.
Background technology
Simple tactile feedback applies the several years in mobile phone, it is used to create mute prompting, or on the screen
Limited haptic feedback is provided during by next button.One novel " high definition " haptic feedback shows and touch screen can be allowed to have textured surface
Sense of touch, or even smooth plane can be allowed to have embossment appearance.By sense of touch interface, user can not only see the object on screen,
It can also touch and manipulate them, produce more real feeling of immersion.At present, it is mounted with portable set for producing shaking for vibration
Dynamic generator, as making mute prompt facility.Currently widely used is rotor motor and linear motor, but is both existed
The shortcomings that haptic feedback, that is, vibration sense is not clear enough.Chinese patent 201210261797.1 discloses a kind of piezo vibration module.Institute
State piezo vibration module and provide haptic feedback than the rotor motor and linear motor more " high definition ".
According to the piezoelectric vibrating device disclosed in patent 201210261797.1, fixed using both ends, centre connection inertia
The mode of body.The piezoelectric vibrating device span is larger, result in vibrational energy consumption at itself；Meanwhile piezoelectrics are easier to
Generation fatigue fracture；In addition, larger length is also unfavorable for the miniaturization of portable set.
The content of the invention
In order to overcome drawbacks described above, the present invention provides it is a kind of have big vibratory output, it is simple in structure, have longer life it is new
Type piezo vibration module.
The present invention in order to solve its technical problem used by technical solution be：A kind of New-type piezoelectric vibration module, including

Assembly structure is presented, the stent includes left socle and right support, and the left socle and right support are separately fixed at oscillator
Both ends, the mass block is fixed on stent, and interval is kept between oscillator, and the shell is fixed on bottom plate, and will
Oscillator, stent, mass block are contained in the enclosure.
As a further improvement on the present invention, the angle formed between the stent and the oscillator is 0 to arrive 180 degree.
As a further improvement on the present invention, the oscillator is made of upper piezoelectrics, lower piezoelectric body and substrate, the substrate
It is fixed between piezoelectrics and lower piezoelectric body；Or the oscillator fitted in by single side piezoelectrics above substrate or below and
Into.
As a further improvement on the present invention, a fixed block, the oscillator are equipped between the centre of the oscillator and bottom plate
It is fixed on by fixed block gap on bottom plate.
The stent includes left socle and right support, and the left socle and right support are separately fixed at the both ends of oscillator.
As a further improvement on the present invention, the piezoelectrics can be inorganic piezoelectric body, organic piezoelectrics or compound
