Abstract
The invention discloses a panel type loudspeaker used for a mobile phone or a tablet computer. A rear cover of the mobile phone or the tablet computer is provided with a recessed cavity. A thin-film coupling sheet made of soft material and a multilayer piezoelectric ceramic sheet are adhered in the recessed cavity from inside to outside in turn. One side, which is used for accessing electrical signals for the multilayer piezoelectric ceramic sheet, of a flexible circuit board is pressed on the multilayer piezoelectric ceramic sheet, and the other side of the flexible circuit board is pressed on the rear cover. According to the panel type loudspeaker, precious installation space in the mobile phone or the tablet computer is almost not occupied and sound-producing holes do not need to be arranged. Besides, the mobile phone or the tablet computer is great in waterproof and dustproof effect, and sound can be clearly heard in a noisy environment.
Description
Technical field
The present invention relates to the loud speaker field for mobile phone or panel computer.
Background technology
In mobile phone or panel computer, conventional loud speaker is coil-moving speaker at present, the shortcoming that existing coil-moving speaker exists is: the installing space taking is larger, on shell, need to set out sound hole, and set out the mobile phone of sound hole or the waterproof and dustproof weak effect of panel computer, in addition, coil-moving speaker is difficult to very clearly not hear sound under noisy environment.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of and take up room littlely, without setting out sound hole, waterproof and dustproof is effective, and can in noisy environment, not hear the panel type loud speaker for mobile phone or panel computer of sound.
For solving the problems of the technologies described above, the present invention has adopted following technical scheme.
Panel type loud speaker for mobile phone or panel computer, be characterized in: on the bonnet of mobile phone or panel computer, be provided with cavity, in cavity by inner film coupling piece and the multilayer piezoelectric ceramic sheet that is pasted with successively outward soft material, one side of accessing the flexible electric circuit board of the signal of telecommunication for multilayer piezoelectric ceramic sheet is pressed against on multilayer piezoelectric ceramic sheet, and the another side of flexible electric circuit board is pressed against on bonnet.
Further, the aforesaid panel type loud speaker for mobile phone or panel computer, wherein: the degree of depth of cavity is 0.3~0.4mm.
Further, the aforesaid panel type loud speaker for mobile phone or panel computer, wherein: the protruding wiring point that is provided with to access the signal of telecommunication on the outer surface that is pressed against the flexible electric circuit board on bonnet.
Beneficial effect of the present invention: take hardly installing space valuable in mobile phone or panel computer, without setting out sound hole; The waterproof and dustproof of mobile phone or panel computer is effective, and can clearly not hear sound in noisy environment.
Accompanying drawing explanation
Fig. 1 is the structural representation of the panel type loud speaker for mobile phone or panel computer of the present invention.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the panel type loud speaker for mobile phone or panel computer of the present invention is further described.
Shown in Figure 1, panel type loud speaker for mobile phone or panel computer of the present invention, on the bonnet 1 of mobile phone or panel computer, being provided with cavity 11---in the present embodiment, the degree of depth of cavity 11 is 0.3~0.4mm, in cavity 11 by inner film coupling piece 2 and the multilayer piezoelectric ceramic sheet 3 that is pasted with successively outward soft material, film coupling piece 2 is made by resin or macromolecular material, for one side of the flexible electric circuit board 4 of the multilayer piezoelectric ceramic sheet 3 access signals of telecommunication is pressed against on multilayer piezoelectric ceramic sheet 3, the another side of flexible electric circuit board 4 is pressed against on bonnet 1.In the present embodiment, on the outer surface that is pressed against the flexible electric circuit board 4 on bonnet 1, be provided with to access the protruding wiring point 5 of the signal of telecommunication, like this after the bonnet 1 that closes, wiring point 5 conducting that can the signal output point directly and on wiring board in mobile phone or panel computer contacts.
The operation principle of the panel type loud speaker for mobile phone or panel computer of the present invention is as follows: when feeding multilayer piezoelectric ceramic sheet 3 audio electrical signal by flexible electric circuit board 4, multilayer piezoelectric ceramic sheet 3 will produce audio frequency vibration, promote bonnet 1 conduction sound, realize loudspeaker function.
Claims (3)
1. for the panel type loud speaker of mobile phone or panel computer, it is characterized in that: on the bonnet of mobile phone or panel computer, be provided with cavity, in cavity by inner film coupling piece and the multilayer piezoelectric ceramic sheet that is pasted with successively outward soft material, one side of accessing the flexible electric circuit board of the signal of telecommunication for multilayer piezoelectric ceramic sheet is pressed against on multilayer piezoelectric ceramic sheet, and the another side of flexible electric circuit board is pressed against on bonnet.
