Abstract
The invention discloses a single-crystal piezoelectric ceramic receiver used for a mobile phone and a tablet computer. The receiver comprises a TP screen. A double-faced adhesive tape is adhered on the internal side surface of the TP screen. A metal thin-film is adhered on the double-faced adhesive tape. An insulating film is adhered on the metal thin-film. A multilayer single-crystal piezoelectric ceramic sheet is adhered on the insulating film. The multilayer single-crystal piezoelectric ceramic sheet is connected with a flexible circuit board used for transmitting electrical signals to the multilayer single-crystal piezoelectric ceramic sheet. The aforementioned single-crystal piezoelectric ceramic receiver is small in occupied cavity space so that precious installation space in the mobile phone or the tablet computer is greatly saved. Besides, sound-transmitting holes do not need to be arranged on the TP screen so that hole-punching cost of the TP screen is saved, production yield rate of the TP screen is enhanced and waterproof and dustproof performance of the mobile phone or the tablet computer is enhanced. Furthermore, conversation contents of an incoming call can be quite clearly heard only by attaching the TP screen to a jaw part or an ear part in a noisy environment.
Description
Technical field
The present invention relates to receiver, refer 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 the TP screen waterproof and dustproof effect of offering after penetrable sound hole is poor, in addition, uses moving coil receiver cannot very clearly not hear incoming call under noisy environment.
Summary of the invention
The technical problem to be solved in the present invention 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 monocrystalline piezoelectric ceramic reciever on mobile phone, panel computer.
For solving the problems of the technologies described above, the present invention has adopted following technical scheme.
For the monocrystalline piezoelectric ceramic reciever 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 metallic film, on metallic film, be pasted with dielectric film, on dielectric film, be pasted with multilayer monocrystalline piezoelectric potsherd, on multilayer monocrystalline piezoelectric potsherd, connect promising its and carry the flexible electric circuit board of the signal of telecommunication.
Further, aforesaid for the monocrystalline piezoelectric ceramic reciever on mobile phone, panel computer, wherein: the thickness of double faced adhesive tape is 0.5～3mm.
Beneficial effect of the present invention: the shared cavity space of described monocrystalline piezoelectric ceramic reciever is little, greatly saved installing space valuable in mobile phone or panel computer, and on TP screen without opening penetrable sound hole, saved 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 He Buhuo 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 monocrystalline piezoelectric ceramic reciever on mobile phone, panel computer of the present invention.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to of the present invention, for the monocrystalline piezoelectric ceramic reciever on mobile phone, panel computer, be further described.
Shown in Figure 1, of the present invention for the monocrystalline piezoelectric ceramic reciever 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 metallic film 3, on metallic film 3, be pasted with dielectric film 4, on dielectric film 4, be pasted with multilayer monocrystalline piezoelectric potsherd 5, on multilayer monocrystalline piezoelectric potsherd 5, connect promising its and carry the flexible electric circuit board 6 of the signal of telecommunication.
Operation principle for the monocrystalline piezoelectric ceramic reciever on mobile phone, panel computer of the present invention is as follows: when feeding multilayer monocrystalline piezoelectric potsherd 5 audio electrical signal by flexible electric circuit board 6, multilayer monocrystalline piezoelectric potsherd 5 will produce audio frequency vibration, thereby drive metallic film 3 to produce together audio frequency vibration, promote TP screen 1 conduction sound, realize receiver function.
Claims (2)
1. for the monocrystalline piezoelectric ceramic reciever 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 metallic film, on metallic film, be pasted with dielectric film, on dielectric film, be pasted with multilayer monocrystalline piezoelectric potsherd, on multilayer monocrystalline piezoelectric potsherd, connect promising its and carry the flexible electric circuit board of the signal of telecommunication.
