Abstract
The utility model discloses a bicrystal piezoelectric ceramic telephone receiver used for a cell phone or a tablet PC. The bicrystal piezoelectric ceramic telephone receiver comprises a TP screen, an inner side surface of which is provided with a double faced adhesive tape in an adhesive manner. The double faced adhesive tape is provided with a multi-layer bicrystal ceramic wafer in an adhesive manner, and the multi-layer bicrystal ceramic wafer is connected with a flexible circuit board used for transmitting electric signals for the multi-layer bicrystal ceramic wafer. The bicrystal piezoelectric ceramic telephone receiver is advantageous in that the cavity space occupied by the bicrystal piezoelectric ceramic telephone receiver is small, and therefore the precious installation space in the cell phone or the tablet PC can be greatly saved; the TP screen is free of acoustic transmission holes, and therefore the perforation costs of the TP screen can be saved, the production yield of the TP screen can be improved, and the waterproof performance and the dustproof performance of the cell phone or the tablet PC can be improved; and in the noisy environment, the TP screen can be attached to the chin or the ear, and then the user can hear the content of the incoming calls clearly.
Description
Technical field
The utility model relates to receiver, refers more particularly to for the receiver on mobile phone, panel computer.
Background technology
Conventional is moving coil receiver for the receiver on mobile phone, panel computer at present, moving coil receiver is positioned at the housing of mobile phone or panel computer, on the TP of mobile phone or panel computer screen, offer penetrable sound hole, moving coil receiver spreads out of sound by penetrable sound hole.
The shortcoming that the receiver of said structure exists is: moving coil receiver has taken cavity space more in mobile phone or panel computer, also need on TP screen, offer penetrable sound hole, offering penetrable sound hole at least needs the expense of 2~3 yuan, and production cost is higher, also easily breaks TP screen; And it is poor to offer TP after penetrable sound hole screen waterproof and dustproof effect, in addition, uses moving coil receiver cannot very clearly not hear incoming call under noisy environment.
Utility model content
The technical problems to be solved in the utility model is: provide on a kind of TP screen without opening penetrable sound hole, and waterproof and dustproof is effective, under noisy environment, can clearly not hear incoming call for the twin crystal piezolelectric ceramic receriver on mobile phone, panel computer.
For solving the problems of the technologies described above, the utility model has adopted following technical scheme.
For the twin crystal piezolelectric ceramic receriver on mobile phone, panel computer, comprise TP screen, be characterized in: on the medial surface of TP screen, be pasted with double faced adhesive tape, on double faced adhesive tape, be pasted with multilayer twin crystal piezoelectric ceramic piece, on multilayer twin crystal piezoelectric ceramic piece, connect the flexible electric circuit board of promising its conveying signal of telecommunication.
Further, aforesaid for the twin crystal piezolelectric ceramic receriver on mobile phone, panel computer, wherein: the thickness of double faced adhesive tape is 0.5~3mm.
The beneficial effects of the utility model: the shared cavity space of described twin crystal piezolelectric ceramic receriver is little, greatly save installing space valuable in mobile phone or panel computer, and on TP screen without opening penetrable sound hole, save the punching expense of TP screen, promote the production qualification rate of TP screen, improved the waterproof and dustproof performance of mobile phone or panel computer; And under noisy environment, only need, by TP screen laminating jaw portion or ear, get final product the gem-pure incoming call dialog context of not hearing.
Accompanying drawing explanation
Fig. 1 is the structural representation for the twin crystal piezolelectric ceramic receriver on mobile phone, panel computer described in the utility model.
Embodiment
Be further described for the twin crystal piezolelectric ceramic receriver on mobile phone, panel computer described in the utility model below in conjunction with accompanying drawing and preferred embodiment.
Shown in Figure 1, described in the utility model for the twin crystal piezolelectric ceramic receriver on mobile phone, panel computer, comprise TP screen 1, on the medial surface of TP screen 1, be pasted with the double faced adhesive tape 2 that thickness is 0.5~3mm, on double faced adhesive tape 2, be pasted with multilayer twin crystal piezoelectric ceramic piece 3, on multilayer twin crystal piezoelectric ceramic piece 3, connect the flexible electric circuit board 4 of promising its conveying signal of telecommunication.
Operation principle for the twin crystal piezolelectric ceramic receriver on mobile phone, panel computer described in the utility model is as follows: when feed multilayer twin crystal piezoelectric ceramic piece 3 audio electrical signal by flexible electric circuit board 4, multilayer twin crystal piezoelectric ceramic piece 3 will produce audio frequency vibration, promote TP screen 1 conduction sound, realize receiver function.
Claims (2)
1. for the twin crystal piezolelectric ceramic receriver on mobile phone, panel computer, comprise TP screen, it is characterized in that: on the medial surface of TP screen, be pasted with double faced adhesive tape, on double faced adhesive tape, be pasted with multilayer twin crystal piezoelectric ceramic piece, on multilayer twin crystal piezoelectric ceramic piece, connect the flexible electric circuit board of promising its conveying signal of telecommunication.
2. according to claim 1 for the twin crystal piezolelectric ceramic receriver on mobile phone, panel computer, it is characterized in that: the thickness of double faced adhesive tape is 0.5~3mm.
