(II) technical scheme

In order to achieve the above purpose, the utility model provides the following technical scheme: three proofings cell-phone loudspeaker incline and go out sound waterproof construction, which comprises an outer shell, the gum, sealing ring and loudspeaker, the shell is in the same place with the gum assembly, and seted up out the sound hole on the shell, loudspeaker set up the inside at the gum, and the play sound hole position on the play sound mouth of loudspeaker and the shell corresponds, the junction joint between gum and the loudspeaker has the sealing ring, through having increased the sealing ring, can increase the shell, leakproofness between gum and the loudspeaker, it has waterproof unstability to have solved old subsides gum structure, the poor problem of leakproofness, and the gum can not reuse need to change one when avoiding machine maintenance, the problem of increase cost.

Preferably, the spread groove has been seted up to one side that the gum corresponds the sealing ring, and integrated into one piece has annular protrusion on the position that the sealing ring corresponds the spread groove, can make being connected between gum and the sealing ring more stable through having set up annular protrusion, prevents to drop.

Preferably, the inside one side that is close to the sound outlet hole of spread groove has seted up the chute, and the chute cross section is triangle-shaped, and when the annular is protruding to be blocked inside the spread groove, the annular is protruding can be filled and is entered into the chute inside, and the setting in cooperation chute triangular groove can further avoid the sealing ring to drop.

Preferably, the spread groove corresponds and has seted up intensive joint groove on the bellied one side inner wall of annular, the annular is protruding to have the joint protruding with the integrated into one piece is intensive on the position that the joint groove corresponds, and such setting can make joint protruding block with the joint groove, increases the stability of connecting.

Preferably, the cross sections of the clamping protrusions and the clamping grooves are semicircular or triangular.

(III) advantageous effects

Compared with the prior art, the utility model provides a side sound-emitting waterproof structure of a three-prevention mobile phone loudspeaker, which has the following beneficial effects:

1. this three proofings cell-phone loudspeaker inclines out sound waterproof construction through having increased the sealing ring, can increase the leakproofness between shell, gum and the loudspeaker, has solved old gum pasting structure and has waterproof unstability, the poor problem of leakproofness, and the gum can not reuse need change one when avoiding machine maintenance, problem of incremental cost.

2. This three proofings cell-phone loudspeaker inclines out sound waterproof construction can make being connected between gum and the sealing ring more stable through having set up annular arch, prevents to drop.

3. This three proofings cell-phone loudspeaker incline and go out sound waterproof construction, when the inside spread groove is gone into to annular protruding card, inside the annular arch can be filled and enter into the chute, the setting in cooperation chute triangular groove, the avoiding sealing ring that can step forward drops.

Drawings

FIG. 1 is a schematic cross-sectional view of a waterproof structure of the present invention;

fig. 2 is a partially enlarged view of a portion a in fig. 1.

In the figure: 1. a housing; 2. carrying out gum application; 3. a seal ring; 4. an annular projection; 5. a horn; 6. a chute; 7. connecting grooves; 8. clamping the bulges; 9. a clamping groove.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Please refer to fig. 1-2, three proofings cell-phone loudspeaker side play sound waterproof construction, including shell 1, gum 2, sealing ring 3 and loudspeaker 5, shell 1 and gum 2 assemble together, and seted up out the sound hole on the shell 1, loudspeaker 5 sets up the inside at gum 2, and loudspeaker 5's sound outlet corresponds with the play sound hole position on the shell 1, the junction joint between gum 2 and loudspeaker 5 has sealing ring 3, through having increased sealing ring 3, can increase shell 1, the leakproofness between gum 2 and the loudspeaker 5, it has waterproof unstability to have solved old gum-adhered structure, the poor problem of leakproofness, and the gum can not be used again and need be changed when avoiding machine maintenance, the problem of increase cost.
