Description
[technical field]
The utility model relates to vibration sounding field, relates in particular to a kind of dull and stereotyped sound-producing device.
[background technology]
Along with the arrival in mobile Internet epoch, the quantity of Intelligent mobile equipment constantly rises.And among numerous mobile devices, mobile phone is common, the most portable mobile terminal device beyond doubt.At present, the function of mobile phone and various, one of them is high-quality music function, and loud speaker in mobile phone is one of essential condition realizing this high-quality music function.Current mobile phone on the market, generally adopt minisize electromagnetic loud speaker to realize the playing function of music, but the product structure of this kind of structure is complicated, and take interior of mobile phone space, because of minisize electromagnetic loud speaker self, need certain height simultaneously, thereby seriously limited the slimming development of the mobile terminals such as mobile phone.
Development along with social science and technology, utilize the mobile phone of dull and stereotyped vocal skill to start to occur, but this mobile phone is all generally the display screen sounding that utilizes mobile phone, because the material of mobile phone screen is more single, general is all frangible glass material, thickness can not arbitrarily regulate, cause the tonequality of the sound that screen sends to be difficult to promote, simultaneously, this technology is applied on screen to also more complicated, piezoelectric vibrator and screen need to be fixed, when assembling, easily damage glass screen, cause the significantly raising of production cost, therefore restricted the development of current dull and stereotyped vocal skill.
So need to provide a kind of novel dull and stereotyped sound-producing device in order to address the above problem.
[utility model content]
The purpose of this utility model is to provide a kind of dull and stereotyped sound-producing device, and it has solved existing dull and stereotyped vocal skill and has utilized display screen to do oscillating plate, causes assembling difficulty, the high problem of the frangible production cost causing of glass screen.
A kind of dull and stereotyped sound-producing device, it comprises cover plate and strip piezoelectric vibrator, described cover plate is provided with through hole, described dull and stereotyped sound-producing device also comprise be contained in described through hole and by described piezoelectric vibrator drive with vibrative oscillating plate with for being connected the connector of described oscillating plate and cover plate, the vertical described oscillating plate of direction of vibration of described piezoelectric vibrator, described piezoelectric vibrator is fixed on cover plate across two ends on described oscillating plate setting and its long axis direction.
Preferably, described connector and oscillating plate contour shape match and its cross section is down T-shape, it comprises the sidewall of diapire and vertical diapire, described sidewall is arranged between oscillating plate and cover plate and for filling the gap between full oscillating plate and cover plate, and the lower surface at the edge of described oscillating plate and cover plate is immobilizated in respectively the upper surface of the diapire of sidewall both sides.
Preferably, the upper surface of oscillating plate, the upper surface of the sidewall of the upper surface of cover plate and connector in same level.
Preferably, between oscillating plate, cover plate and connector, by glue, be mutually adhesively fixed.
Preferably, two boss are extended in the position of two ends of the corresponding piezoelectric vibrator of described cover plate, and this boss is fixed in described end.
The utility model provides a kind of dull and stereotyped sound-producing device, and it can be applied in various electronic equipments, not only easily application, and also application cost is cheap.
[accompanying drawing explanation]
Fig. 1 is the exploded view that the utility model embodiment applies the cell phone rear cover of dull and stereotyped sound-producing device;
Fig. 2 is the cutaway view of cell phone rear cover shown in Fig. 1;
Fig. 3 is the enlarged drawing of the local A of cutaway view shown in Fig. 2.
[embodiment]
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only a part of embodiment of the utility model, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
For clear detailed description the utility model, below the embodiment dull and stereotyped sound-producing device of the utility model being applied on cell phone rear cover for is described.
As depicted in figs. 1 and 2, a kind of cell phone rear cover being applied on conventional mobile phone, this cell phone rear cover has been applied the dull and stereotyped sound-producing device that the utility model provides, described dull and stereotyped sound-producing device comprises cover plate 1 and strip piezoelectric vibrator 2, described cover plate 1 is provided with through hole 10, described dull and stereotyped sound-producing device also comprise be contained in described through hole 10 and by described piezoelectric vibrator 2 drive with vibrative oscillating plate 3 with for being connected the connector 4 of described oscillating plate 3 and cover plate 1, the vertical described oscillating plate 3 of direction of vibration of described piezoelectric vibrator 2, described piezoelectric vibrator 2 is fixed on cover plate 1 across two ends 20 on described oscillating plate 3 settings and its long axis direction, described cover plate 1 arranges around described oscillating plate 3 and with described oscillating plate 3 intervals.Two boss 11 are extended in the position of two ends 20 of the corresponding piezoelectric vibrator 2 of described cover plate 1, and this boss 11 is fixed in described end 20.
Described piezoelectric vibrator 2 also comprises that the 21，Gai vibration section, vibration section 21 being positioned in the middle of it can be directly fixed on the central authorities of described oscillating plate 3, also can connect vibration section 21 and oscillating plate 3 by other vibration transmission member.
Again in conjunction with shown in Fig. 3, described connector 4 matches with oscillating plate 3 contour shapes and cross section is down T-shape, it comprises the sidewall 41 of diapire 40 and vertical diapire 40, and described sidewall 41 is arranged between oscillating plate 3 and cover plate 1 for filling gap between full oscillating plate 3 and cover plate 1 to play sealing.Described oscillating plate 3 is immobilizated in respectively the upper surface of the diapire 40 of sidewall 41 both sides with the lower surface at the edge of cover plate 1, and by glue, is mutually adhesively fixed between described oscillating plate 3, cover plate 1 and connector 4.In order to make the outer surface of this cover plate sound-producing device smooth, the upper surface of the upper surface of the upper surface of oscillating plate 3, cover plate 1 and the sidewall 41 of connector 4 is in same level.
The dull and stereotyped sound-producing device that the utility model provides, it not only can be applied on cell phone rear cover, can also be applied in other various electronic equipments, because the material unlike glass display screen of the sheathing material as cell phone rear cover and so on is single frangible, it can adopt different materials to make bonnet as required, especially the dull and stereotyped sound-producing device that the utility model provides, oscillating plate 3 is for vibration, oscillating plate 3 arranges with cover plate 1 interval, therefore, in fact only need to change oscillating plate 3 just can regulate the tonequality of sent sound, therefore, the dull and stereotyped sound-producing device that the utility model provides is not only easily employed, and application cost is cheap.
Above-described is only better embodiment of the present utility model; at this, it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model creation design; can also make improvement, but these all belong to protection range of the present utility model.
