However, the shortcoming that existing speaker unit is not strong there are waterproofness.It as shown in Figure 1 and Figure 2, is existing
Some speaker units, the speaker unit include upper cover 1, assemble the lower cover 2 to form accommodating space, receiving with the upper cover 1
In the sounding monomer 3 in the accommodating space, upper cover 1 is provided with supporting beam 11, the monomer at the position close to sound outlet hole 4
3 shapes and the cooperation of upper cover 1 position.When 3 side gluing of monomer, because air trapping is in the bottom surface of gluing slot, list cannot be filled up completely
Gap between 3 side of body and cover board 1, in this way, the side of monomer cannot play the function of waterproof, when monomer sound film face and lid
When glue fails between plate, water can flow into the back cavity through entering speaker unit inside monomer from monomer side, damage loudspeaker
Device.
[summary of the invention]
The purpose of the present invention is to provide a kind of speaker units, it is intended to solve to be filled up completely when the gluing of monomer side
Gap between monomer side and cover board, the technical issues of eventually leading to speaker unit waterproof failure.
Technical scheme is as follows: a kind of speaker unit, including upper cover, lower cover and sounding monomer, the upper cover
An accommodating chamber is fixedly connected with and formed with the lower cover, and the sounding monomer is mounted in the accommodating chamber, and the upper cover opens up
There is sound mouth and the upper cover toward sounding monomer direction extends a supporting beam, the supporting beam includes the first adjacent table
Face and second surface, the sounding monomer include close to the first end face of upper cover and close to the sound mouth and with described the
The adjacent second end face in one end face, the first surface is opposite with the first end face, and by filling between the two
One adhesive carries out glue seals to form first of waterproof construction, and the second surface is opposite with the second end face, described
The junction of first surface and the second surface is recessed to form an air reservoir toward far from sounding monomer direction, described the
By the second adhesive of filling and the second adhesive seepage flow is into the air reservoir between two surfaces and the second end face
It is stored in the air reservoir with carrying out glue seals to form the air blocked when second waterproof construction.
Further, the first surface and the second surface are orthogonal.
Further, the junction of the first surface and the second surface, towards perpendicular to the first surface side
It concaves to form the air reservoir.
Further, the air reservoir is square groove.
Further, first adhesive and second adhesive are glue.
Further, location structure is additionally provided between the upper cover and the sounding monomer.
Further, the location structure includes positioning column and locating slot, and the positioning column and the locating slot can be mutual
In the upper cover and the sounding monomer, the positioning column and the locating slot are mating for the setting changed.
The beneficial effects of the present invention are: the present invention is by adding an air reservoir, for storing the sky being discharged not in time
Gas, in this way, glue can well expire the gap filling between monomer and supporting beam when monomer carries out side gluing, thus
It constructs to form second waterproof barrier, when positive first of waterproof barrier fails between monomer sound film face and cover board, second
The presence of waterproof construction can also play waterproof effect, thus substantially increase speaker unit waterproof yield and waterproof it is reliable
Property.
