Description
[technical field]
The utility model relates to a kind of dull and stereotyped sonification system, specifically refers to a kind of screen acoustical generator.
[background technology]
Along with the development in portable consumer electronic product market, the screen acoustical generator has been subjected to people's attention more and more.Requirement of client is also answered by manufacturer, applies it in all kinds of portable type electronic products, for example: mobile phone, notebook computer, panel computer, digital photo frame, multimedia player etc.The sounding principle of screen acoustical generator is: the screen of electronic equipment is passed in the vibration that will be installed in the motor transducer on the electronic equipment, passes through the effect of the vibration realizing sounding of screen then.
Screen acoustical generator in the correlation technique generally includes the support of screen, piezoelectric vibrator and fixing described piezoelectric vibrator, and described piezoelectric vibrator comprises substrate, potsherd and is fixed in described potsherd top and supports the cushion block of described screen.Because during the work of screen acoustical generator, screen will produce vibration, and the element that piezoelectric vibrator vibrates as driving, its reliability is very important.Yet, because potsherd itself is more crisp, in vibration processes, easily fracture in the place of fixing described cushion block, in addition, when needs were peeled off piezoelectric vibrator and screen, the potsherd of fixing described cushion block tended to be damaged.
Therefore, be necessary to propose a kind of new technical scheme and solve the problems referred to above.
[utility model content]
The purpose of this utility model is to provide a kind of reliability height and the lower screen acoustical generator of maintenance cost.
The technical solution of the utility model is as follows: a kind of screen acoustical generator, it comprises screen and piezoelectric vibrator, described piezoelectric vibrator comprises tabular substrate and the potsherd that is attached at described substrate, and described substrate has the protuberance that extends upward and be held in described screen from the substrate dual-side.
Preferably, the number of described potsherd is two, is attached at the upper and lower surface of described substrate respectively.
Preferably, described protuberance comprises from the outside horizontally extending connecting portion in the described substrate left and right sides, the terminal upwardly extending riser portions of vertical described connecting portion and connects described riser portions and be held in the contact site of the level of described screen lower surface.
Preferably, has the gap between described protuberance and described potsherd.
Preferably, described protuberance also has reinforcement, and described reinforcement tilts to extend upward and connect the lower surface of described contact site from described riser portions inner surface.
Preferably, has the gap between described reinforcement and described potsherd.
Preferably, described protuberance is positioned at the middle part of described substrate.
Preferably, described protuberance and described substrate are one-body molded.
The beneficial effects of the utility model are: utilize the protuberance that does not contact with potsherd on the substrate to replace cushion block to support screen and drive screen and vibrate, make potsherd not fragile, both improve reliability, because potsherd is damaged the waste that causes, reduced maintenance cost in the time of can reducing dismounting again.

[embodiment]
The utility model is described in further detail below in conjunction with drawings and embodiments.
(embodiment 1)
As shown in Figure 1, the utility model screen acoustical generator 1 comprises screen 11, is positioned at the frame 12 of described screen 11 belows, the support 13 of the described frame 12 of supporting, the bonnet 15 that is fixed in the piezoelectric vibrator 14 of described support 13 and is positioned at described support 13 belows.
As Fig. 2, shown in Figure 3, the potsherd 142 that described piezoelectric vibrator 14 comprises tabular substrate 141 and is attached at described substrate 141 upper and lower surfaces, described substrate 141 has the protuberance 143 that extends upward and be held in described screen 11 from substrate 141 dual-sides.Described protuberance 143 is positioned at the middle part of described substrate 141.
Described protuberance 143 comprises from the outside horizontally extending connecting portion 1431 in described substrate 141 left and right sides, vertical described connecting portion 1431 terminal upwardly extending riser portions 1432 and connects described riser portions 1432 and be held in the contact site 1433 of the level of described screen 11 lower surfaces.
142 of described protuberance 143 and described potsherds have gap 140.
Described protuberance 143 and described substrate 141 are one-body molded.
(embodiment 2)
As shown in Figure 4, the utility model screen acoustical generator 2 comprises screen 21, is positioned at the frame 22 of described screen 21 belows, the support 23 of the described frame 22 of supporting, the bonnet 25 that is fixed in the piezoelectric vibrator 24 of described support 23 and is positioned at described support 23 belows.
As Fig. 5, shown in Figure 6, the potsherd 242 that described piezoelectric vibrator 24 comprises tabular substrate 241 and is attached at described substrate 241 upper and lower surfaces, described substrate 241 has the protuberance 243 that extends upward and be held in described screen 21 from substrate 241 dual-sides.Described protuberance 243 is positioned at the middle part of described substrate 241.
Described protuberance 243 comprises from the outside horizontally extending connecting portion 2431 in described substrate 241 left and right sides, vertical described connecting portion 2431 terminal upwardly extending riser portions 2432, connects described riser portions 2432 and be held in the contact site 2433 of level of described screen 21 lower surfaces and the reinforcement 2434 that tilts to extend upward and connect the lower surface of described contact site 2433 from described riser portions 2432 inner surfaces.Described reinforcement 2434 has been reinforced described protuberance 243, makes described protuberance 243 not yielding in vibration processes, thereby more efficiently the displacement of piezoelectric vibrator 24 is passed to screen 21.
