Description
Technical field
This utility model relates to loudspeaker technical field, is specifically related to piezoelectric loudspeaker.
Background technology
Electromagnetic type loudspeaker currently on the market are the most conventional a kind of electro-acoustic transducer devices, it is generally used for home theater, multi-media sound system, notebook computer etc., but owing to its work can produce electromagnetic wave, require higher application can impact to electromagnetic interference at some, it is therefore desirable to designing a kind of is that the generation without electromagnetic wave can meet again the loudspeaker using requirement at work.
Utility model content
The purpose of this utility model is the defect for prior art and deficiency, it is provided that a kind of simple in construction, piezoelectric loudspeaker reasonable in design, easy to use, and it can respond at low frequency, and has low-power consumption, without noise, without features such as electromagnetic interference.
In order to solve the problem existing for background technology, the technical solution adopted in the utility model is: it includes sound basin, shell, Metal screen cloth, metallic conduction sticker, bonnet, pad, tubular rivet, screw, piezoelectric ceramic piece；The two sides of described Metal screen cloth is pasted with piezoelectric ceramic piece by glue respectively, metallic conduction sticker is respectively adhered on the piezoelectric ceramic piece silver electrode of positive and negative, the connecting hole of metallic conduction sticker and the connection hole of Metal screen cloth are provided with pad, connection hole is provided with tubular rivet, Metal screen cloth and metallic conduction sticker are between shell and bonnet, and shell is screwed with bonnet, and the midpoint of piezoelectric ceramic piece is equipped with fixing glue, sound basin is installed in the enclosure, is connected with piezoelectric ceramic piece.
After using said structure, this utility model has the beneficial effect that it can respond at low frequency, and has low-power consumption, without noise, without features such as electromagnetic interference.

Detailed description of the invention
Below in conjunction with the accompanying drawings, this utility model is further described.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the drawings and the specific embodiments, this utility model is further elaborated.Should be appreciated that detailed description of the invention described herein, only in order to explain this utility model, is not used to limit this utility model.
As Figure 1-Figure 4, this detailed description of the invention adopts the following technical scheme that it includes sound basin 1, shell 2, Metal screen cloth 3, metallic conduction sticker 4, bonnet 5, pad 6, tubular rivet 7, screw 8, piezoelectric ceramic piece 9；The two sides of described Metal screen cloth 3 is pasted with piezoelectric ceramic piece 9 by glue respectively, metallic conduction sticker 4 is respectively adhered on piezoelectric ceramic piece 9 silver electrode of positive and negative, the connecting hole of metallic conduction sticker 4 and the connection hole of Metal screen cloth 3 are provided with pad 6, connection hole is provided with tubular rivet 7, Metal screen cloth 3 and metallic conduction sticker 4 are between shell 2 and bonnet 5, shell 2 is fixed by screw 8 with bonnet 5, fixing glue it is equipped with on the midpoint of piezoelectric ceramic piece 9, sound basin 1 is arranged in shell 2, is connected with piezoelectric ceramic piece 9.
Piezoelectric ceramic piece 9 on Metal screen cloth 3 two sides fastens with glue respectively, metallic conduction sticker 4 is respectively adhered on piezoelectric ceramic piece 9 silver electrode of positive and negative, pad 6 is installed at the connecting hole of metallic conduction sticker 4 and the connection hole of Metal screen cloth 3, and rivet tightly with tubular rivet 7, then it is installed in shell 2 and bonnet 5, stamp screw 8 to fix, the midpoint of piezoelectric ceramic piece 9 is stamped fixing glue, again sound basin 1 is arranged in shell 2, it is connected with piezoelectric ceramic piece 9, its operation principle is when audio signal is by piezoelectric ceramic piece 9, mechanically deform is produced because of inverse piezoelectric effect, the sound basin 1 being fixed on shell 2 is driven to vibrate, produce resonance with the air of surrounding and send sound.
This detailed description of the invention can respond at low frequency, and has low-power consumption, without noise, without features such as electromagnetic interference.
The above, only in order to the technical solution of the utility model to be described and unrestricted, other amendment or equivalent that the technical solution of the utility model is made by those of ordinary skill in the art, without departing from the spirit and scope of technical solutions of the utility model, all should contain in the middle of right of the present utility model.
