State chamber sheet in vitro and be connected by solder joint with the wiring board.
In above-mentioned water-proof type acoustics cavity body structure, the cavity body structure is installed in peripheral hardware sound device, the peripheral hardware
The through hole to match with the osculum is offered on sound device.
In above-mentioned water-proof type acoustics cavity body structure, the number at least two of the osculum.
In above-mentioned water-proof type acoustics cavity body structure, the material of the chamber body is plastic material, and the piezoelectric patches passes through
Adhesive is connected with the chamber body.
The beneficial effects of the utility model：
The utility model cavity body structure can increase water-proof function, structure letter newly while client is met to sound press demand
It is single, it is practical, it is easy to batch production to manufacture, suitable for all kinds of outdoor installations, portable set and marine equipment etc. have anti-
The place of water demand.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
Art means, and being practiced according to the content of specification, with preferred embodiment of the present utility model and coordinate accompanying drawing detailed below
Describe in detail bright as after.Specific embodiment of the present utility model is shown in detail by following examples and its accompanying drawing.
Brief description of the drawings
Accompanying drawing described herein is used for providing further understanding to of the present utility model, forms the part of the application,
Schematic description and description of the present utility model is used to explain the utility model, does not form to of the present utility model improper
Limit.In the accompanying drawings：
Fig. 1 is a kind of structural representation of water-proof type acoustics cavity body structure of the present utility model.
Label declaration in figure：
1st, chamber body, 2, sound hole, 3, piezoelectric patches, 4, wiring board, 5, wire, 6, PIN needle, 7, osculum.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in detail.
Shown in Figure 1, a kind of water-proof type acoustics cavity body structure, the cavity body structure includes chamber body 1, sound hole 2, pressure
Electric piece 3, wiring board 4, wire 5 and PIN needle 6, the piezoelectric patches 3 are laterally interior located at the middle part of chamber body 1, the sound hole 2
The space of a closing is formed located at the middle part of the upper end of the chamber body 1 and with the chamber body 1, the wiring board 4 is located at
The lower end of chamber body 1, the wire 5 are connected with the piezoelectric patches 3 and the wiring board 4 respectively by solder joint, the PIN needle
6 are connected outside the chamber body 1 and by solder joint with the wiring board 4.The side wall of the chamber body 1 is provided with the external world even
Osculum 7 logical and that water can be allowed to discharge, the osculum 7 are opened in the upper edge of the piezoelectric patches 3, the osculum 7
For square through hole.In the present embodiment, the osculum 7 is square through hole, and compared to circular port, the globule of being so more convenient for is suitable
Profit discharge cavity.
In the present embodiment, as shown in figure 1, the number of the osculum 7 is one；In other embodiments, institute
The number for stating osculum 7 can be two or more, and be opened in the upper edge of the piezoelectric patches 3, so can further increase
Add drainage effect, improve the water proofing property of cavity.The big I in hole of the osculum 7 carries out corresponding according to the size of chamber body 1
Adjustment.
In actual applications, the cavity body structure is installed in peripheral hardware sound device, is opened up on the peripheral hardware sound device
There is the through hole to match with the osculum 7.Specifically, one and the draining can be opened up in the side wall of peripheral hardware sound device
