Description
Technical field
The utility model relates to a kind of technical field of buzzer, especially a kind of patch type electric-type buzzer.
Background technique
Our current patch buzzers, all there is rear cover, need elder generation during installation due to being provided with rear cover
Piezo is fixed in shell, then rear cover is installed on shell, and the fitting method of shell and rear cover has glue bonding, surpasses at present
Sound wave welding etc., and it is easily reduced buzzer production efficiency in this way, in addition rear cover needs to leave mold, cost is increased instead,
And if inside tears poor contact open, needs first to dismantle rear cover, causes later period maintenance inconvenient, and if rear cover accidentally touch during installation
Inside is easy to cause interior contact unstable, influences using effect.
Utility model content
There is provided purpose of the utility model is to solve above-mentioned the deficiencies in the prior art it is a kind of reduce cost, installation more
Convenient, the better patch type electric-type buzzer of stability.
To achieve the goals above, patch type electric-type buzzer designed by the utility model, including shell and piezo,
The weld tabs being embedded on the both sides of the face of shell outside a part exposing, respectively with the first weld tabs and the second weld tabs table
Show, and be isolated between first weld tabs and the second weld tabs by isolation board, the exposed division of first weld tabs and piezo it
Between by the first conductive glue connection, by the second conductive glue connection between the exposed division and piezo of second weld tabs, the
The conductive sheet externally exported is equipped on one weld tabs and the second weld tabs.
Weld tabs of this structure due to being equipped with isolation in the end face two sides of shell, then utilizes the first conducting resinl by the first weld tabs
It welds with piezo one end, and is welded the second weld tabs and the piezo other end using the second conducting resinl, in this way by buzzing
Piece, which is bonded on shell, forms enough sound chambers, to meet requirement of the client to acoustic pressure and compared with prior art without rear cover,
Its process is simpler, strong operability, in this way can be to realize that automated production provides feasibility condition later, to mention
The working efficiency of high product, and rear cover is processed without in addition die sinking, to piezo without shadow when eventually reducing cost, and installing
It rings, therefore this structure has and " produces that high-efficient, production cost is low, do not influenced in use by assembling, improve work effect
The advantages of rate ".
Further, convenient for fixing, it is equipped with the step surface for placing piezo on shell, is equipped in the outside of step surface
Raised end face, the weld tabs are placed on raised end face, and flush with piezo.
Further, in order to improve fixed effect, on the first conducting resinl between the exposed division and piezo of the first weld tabs
And one layer of protection glue-line is equipped on the second conducting resinl between the exposed division and piezo of the second weld tabs, by playing protection
Glue simultaneously is allowed to solidify, and realization plays a protective role to piezo and conducting resinl.
The patch type electric-type buzzer that the utility model obtains, compared with prior art, high production efficiency, production cost are low,
It is not influenced by assembling, is improved work efficiency in use.

Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
Embodiment 1:
As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of patch type electric-type buzzer provided in this embodiment, including 1 He of shell
Piezo 2, be embedded on the both sides of the face of shell 1 part expose outside weld tabs, respectively with the first weld tabs 3 and the
Two weld tabs 4 indicate, and are isolated between first weld tabs 3 and the second weld tabs 4 by isolation board 5, the exposing of first weld tabs 3
It is connected between portion and piezo 2 by the first conducting resinl 6, passes through second between the exposed division and piezo 2 of second weld tabs 4
Conducting resinl 7 connects, and is equipped with the conductive sheet 8 externally exported on the first weld tabs 3 and the second weld tabs 4.
Weld tabs of this structure due to being equipped with isolation in the end face two sides of shell 1, is then welded using the first conducting resinl 6 by first
Piece 3 and 2 one end of piezo are welded, and are welded the second weld tabs 3 with 2 other end of piezo using the second conducting resinl 7, in this way
Piezo 2 is bonded on shell 1 and forms enough sound chambers, to meet requirement of the client to acoustic pressure, and compared with prior art
There is no rear cover, process is simpler, strong operability, can provide feasibility item in this way for realization automated production later
Part to improve the working efficiency of product, and processes rear cover without in addition die sinking, when eventually reducing cost, and installing pair
Piezo 2 without influence, therefore this structure have " produce that high-efficient, production cost is low, do not influenced in use by assembling,
Improve work efficiency " the advantages of.
Further, convenient for fixing, the step surface 9 for placing piezo 2 is equipped on shell 1, in the outside of step surface 9
Equipped with raised end face 10, the weld tabs is placed on raised end face 10, and flushes with piezo 2.
Further, the first conducting resinl 6 in order to improve fixed effect, between the exposed division and piezo 2 of the first weld tabs 3
It is equipped with one layer of protection glue-line 11 on upper and the second conducting resinl 7 between the exposed division and piezo 2 of the second weld tabs 4, is led to
It crosses and plays protection glue and be allowed to solidify, realization plays a protective role to piezo and conducting resinl.
