Description
Technical field
The utility model is related to technical field of electronic products, more particularly to a kind of loudspeaker module waterproof construction.
Background technology
With the development trend of mobile phone, to the waterproof requirement more and more higher of loudspeaker module, reach that IP8 grades are prevented the need for having
Water, and current structure design and kernel can not all meet high-grade waterproof requirement.
Existing waterproof construction is as shown in figure 1, including lower casing 1 and upper casing 3, upper casing 3 is interior to be provided with ante-chamber 2, and ante-chamber 2 has
Sound mouthful 9, ante-chamber 2 is by sound mouth 9 and ft connection, and lower casing 1 is interior to have back cavity 6, and back cavity 6 is interior to be had before frame 7, frame 7
End is bonded with diaphragm 5, and the rear end and both sides of frame 7 are connected with the side wall of upper casing 3, and the front end of frame 7 is hanging, the front end of frame 7
The position of 2 sound mouth of ante-chamber 9 is arranged on, the main cause that this structure can not meet waterproof requirement is as follows：The sound mouth of module ante-chamber 2
Position, the bottom of diaphragm 5 is supported without plastic cement, and current enter ante-chamber 2, and the adhered layer 4 directly between diaphragm 5 and frame 7 is contacted, because
Not enough, adhered layer 4 is acted on and earned out sticking strength by hydraulic pressure, and the gap that current can be between diaphragm 5 and frame 7 enters
Back cavity 6, it is impossible to meet waterproof requirement.
The main solution of present problem：Increase the bonding area of tack coat 4 between diaphragm 5 and frame 7；From special
The glue of performance, by improving, water resistance is improved to a certain extent, but is difficult still to meet high-grade waterproof requirement.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of loudspeaker module waterproof in view of the shortcomings of the prior art
Structure, this is simple in construction, while can reach IP8 grades of waterproofs.
Following technical scheme is used to solve above-mentioned technical problem the utility model：A kind of loudspeaker module waterproof construction,
Including lower casing and upper casing, ante-chamber is provided with upper casing, ante-chamber has a sound mouth, ante-chamber is by sound mouth and ft connection, in lower casing
With back cavity, there is frame in back cavity, the front end of frame is bonded with diaphragm, the rear end and both sides of frame and upper casing by tack coat
Connection, the front end of frame is positioned close to sound mouth position, and the bottom of diaphragm is provided with supporting member, branch close to the position of sound mouth
Support component is used to support diaphragm, and supporting member is connected with sound mouth, passes through glue bonding between supporting member and diaphragm.
The utility model has following technique effect using above-mentioned technical proposal：It is simple in construction, prevent while can reach IP8 grades
Water.
Above-mentioned technical proposal is described further with reference to the accompanying drawings and examples.
Brief description of the drawings：
Accompanying drawing 1 is the structural representation of loudspeaker module in background technology；
Accompanying drawing 2 is the structural representation of loudspeaker module in the utility model.
In figure：1- lower casings；2- ante-chambers；3- upper casings；4- tack coats；5- diaphragms；6- back cavities；7- frame；8- supporting members；9-
Sound mouth.
Embodiment
Embodiment, as shown in Fig. 2 a kind of loudspeaker module waterproof construction, including lower casing 1 and upper casing 3, is provided with upper casing 3
Ante-chamber 2, ante-chamber 2 has sound mouth 9, and ante-chamber 2 is by sound mouth 9 and ft connection, and lower casing 1 is interior to have tool in back cavity 6, back cavity 6
There is frame 7, the front end of frame 7 is bonded with diaphragm 5 by tack coat 4, and the rear end and both sides of frame 7 are connected with upper casing 3, frame 7
Front end be positioned close to the position of sound mouth 9, the bottom of diaphragm 5 is provided with supporting member 8 close to the position of sound mouth 9, supports structure
Part 8 is used to support diaphragm 5, and supporting member 8 is connected with sound mouth 9, and glue bonding is passed through between supporting member 8 and diaphragm 5.
Supporting member 8 is preferably long strip-board shape support member.
Current enter after ante-chamber 2, it is to avoid the tack coat 4 between the current very first time and frame 7 and diaphragm 5 is directly contacted,
But contacted between elder generation and diaphragm 5 and supporting member 8 at gluing, double insurance, so as to reach high-grade waterproof requirement.
