The piezoelectric vibrator comprises a substrate, piezoelectric sheets, a self-extending supporting sheet and a mass block, wherein the piezoelectric sheets are placed on the two sides of the substrate; and the mass block is placed on the supporting sheet and has a certain distance with the piezoelectric sheets. The piezoelectric vibrator has high stability.
Description
[technical field]
The present invention relates to a kind of piezoelectric vibrator.
[background technology]
Electronic equipment set manufacturer, particularly portable electric appts manufacturer are always in the experience of constantly improving the user.Traditional equipment uses the vision and the sense of hearing to provide feedback as the user, as video playback and voice playing etc.In some equipment, motion feedback (as active force and resistance feedback) and tactile feedback (as vibration, heat energy) can offer the stronger experience of user.Particularly, the haptic effect of vibrating effect, vibrating tactile is providing real feedback to cause the sense organ impression in simulation or virtual environment the inside, can cause the judder of subscriber equipment as the explosive effect of game machine the inside, water droplet then can cause less vibration, the demand of this experience is constantly heated.
Tactile feedback is being integrated in the equipment such as mobile phone, individual palmtop PC, portable game machine, for example some portable game machines can be given the user effect with vibration on joystick, in addition, also can utilize the mode of vibration to carry out operations such as schedule alarm in the individual palmtop PC.
Piezoelectric vibrator is as the main element that tactile feedback is provided, and its structure is also used quilt improvement gradually with it.The piezoelectric vibrator of correlation technique, it comprises substrate, place the piezoelectric patches on substrate two sides and stick on mass on the piezoelectric patches.
Mass utilizes glue directly to stick on the piezoelectric patches.During application, mass comes off from piezoelectric patches easily, influences the stability of vibration of piezoelectric vibrator.In addition, during the piezoelectric patches flexural vibrations, it can produce interference and collision with mass, influences the vibrating effect of piezoelectric vibrator.
Therefore, be necessary to provide a kind of new piezoelectric vibrator to overcome above-mentioned shortcoming.
[summary of the invention]
The object of the present invention is to provide the good piezoelectric vibrator of a kind of stability of vibration.
The object of the present invention is achieved like this: a kind of piezoelectric vibrator, it comprises substrate, places the piezoelectric patches on substrate two sides, wherein, described piezoelectric vibrator also be provided with from the support chip that extends and place on the support chip and with piezoelectric patches mass separated by a distance.
Preferably, described substrate is provided with two first relative long sidewalls, and described support chip comprises from the first long sidewall to extending two stators that are used for fixing mass away from two braces of the direction diagonally extending of substrate with from the end bending of two braces.
Preferably, described mass be provided with the second relative short sidewall of two second relative long sidewalls, two and from the second long sidewall to support portion away from the direction extension of mass, described support portion and stator connect.
Preferably, described stator is parallel with main part.
Preferably, described two stators are connected with each other.
Compare with the piezoelectric vibrator of correlation technique, the mass of piezoelectric vibrator of the present invention with fixedly connected from the extended support chip of substrate, thereby realize the stable fixing of mass, guarantee the stability of vibration of piezoelectric vibrator.In addition, mass and piezoelectric patches are separated by a distance, can not produce interference and collision with mass during the piezoelectric patches flexural vibrations, also guarantee the vibrating effect of piezoelectric vibrator.

[embodiment
Below in conjunction with accompanying drawing, piezoelectric vibrator of the present invention is elaborated.
Please join illustrated in figures 1 and 2ly, piezoelectric vibrator 1 of the present invention is located in the electronic component (not shown), and described electronic component comprises mobile phone, digital camera or other consumption electronic products.
The support chip 30 that piezoelectric vibrator 1 comprises substrate 10, places the piezoelectric patches 20 on substrate two sides, extend from substrate 10 and place on the support chip 30 and with piezoelectric patches 20 mass 40 separated by a distance.
Described substrate 10 is tabular, and it comprises two opposite first 101 and the first side wall 102 that is connected two first surfaces 101, and described the first side wall 102 is provided with two first short sidewalls 1022 that the first relative long sidewall 1021 is relative with two.
It is tabular that mass 40 also is, and it comprises two opposing second surface 401 and second sidewall 402 that is connected two second surfaces, and described second sidewall 402 is provided with two second short sidewalls 4022 that the second relative long sidewall 4021 is relative with two.Mass 40 also is provided with from the second long sidewall 4021 to the support portion 403 of extending away from the direction of mass 40.Described support portion 403 connects with stator 302.
Described piezoelectric patches 20 places respectively on two opposite first 101 of substrate.Piezoelectric patches 20 has inverse piezoelectric effect, promptly under the effect of extra electric field, mechanical deformation takes place.Described piezoelectric patches 20 is made by piezoelectric, and piezoelectric generally comprises piezoelectric crystal, piezoelectric ceramic and organic polymer piezoelectric.In the present embodiment, described piezoelectric patches 20 is to be made by piezoceramic material.Described piezoelectric patches 20 can be set to sandwich construction.
As shown in Figure 3 and Figure 4, during assembling, the mass 40 of piezoelectric vibrator is separated by a distance with piezoelectric patches 20, i.e. first distance D.
The mass of piezoelectric vibrator of the present invention with fixedly connected from the extended support chip of substrate, thereby realize the stable fixing of mass, guarantee the stability of vibration of piezoelectric vibrator.In addition, mass 40 is separated by a distance with piezoelectric patches 20, can not produce interference and collision with mass during the piezoelectric patches flexural vibrations, also guarantees the vibrating effect of piezoelectric vibrator.
The above only is a better embodiment of the present invention; protection scope of the present invention is not exceeded with above-mentioned execution mode; as long as the equivalence that those of ordinary skills do according to disclosed content is modified or changed, all should include in the protection range of putting down in writing in claims.
