Abstract

A case having a speaker mesh module and a manufacturing method thereof are provided. The case includes a base, a speaker mesh module and a combination member. The base is formed with a filling port and an opening in which the speaker mesh module is correspondingly placed. The speaker mesh module is formed with a buckle part and a sound output part. The combination member is secured on the base through the filling port with an injection molding means and served to cover the speaker mesh module. The combination member is formed with a combining part mutually fastened with the buckle part and a penetrated hole corresponding to the sound output part. Accordingly, the speaker mesh module is able to be sealed in the opening with a means other than adhering, thereby allowing the case to be provided with a stable and excellent waterproof performance.

First claim

What is claimed is:

1. A case having a speaker mesh module, including:
a base comprising a wall and a recess formed in an exterior surface of the wall, wherein an opening and a filling port are formed in the recess and penetrate through the wall;
a speaker mesh module comprising an adhesive film and a speaker mesh film, the adhesive film comprising an opening corresponding to the opening in the base, and the speaker mesh film overlaying the openings in the base and the adhesive film; and
a combination member, formed in the recess by injection molding via the filling port and covering the speaker mesh module, the combination member comprising a protruding block formed in and fastened to the filling port, a combining part fastened to the adhesive film, and a hole corresponding to the opening in the base.

2. The case having the speaker mesh module according to claim 1 , wherein the speaker mesh module includes a buckle part composed of at least one groove, the combining part is composed of at least one protrusion extended from the combination member, and the protrusion and the groove are mutually fastened.

3. The case having the speaker mesh module according to claim 2 , wherein the quantity of grooves is plural, and each of the grooves is composed of a slot inwardly formed from the outer periphery of the speaker mesh module.

4. The case having the speaker mesh module according to claim 2 , wherein the quantity of grooves is plural, and each of the grooves is composed of a hollow slot penetrating two surfaces of the speaker mesh module.

5. The case having the speaker mesh module according to claim 1 , wherein speaker mesh film is waterproof.

6. A manufacturing method of a case having a speaker mesh module, including the steps of:
providing a base, wherein a recess is formed in an exterior surface of a wall of the base, and an opening and a filling port are formed in the recess and penetrate through the wall;
disposing a speaker mesh module in the recess, wherein the speaker mess module comprises a speaker mesh film arranged to overlay the opening in the base; and
forming a combination member in the recess by disposing a molding device on the exterior surface of the base, wherein the molding device comprises a cavity arranged over the recess, and disposing an
injection device at an interior surface of the base, and then injecting a forming material through the filling port and then into the cavity of the molding device so as to form the combination member in the recess and secured to the base;
wherein the combination member comprises an hole exposing the speaker mesh film and corresponding to the opening in the base.

7. The manufacturing method of a case having a speaker mesh module according to claim 6 , wherein the forming material fills the filling port to form a protruding block of the combination member, and the protruding block is fastened to the filling port.

8. The manufacturing method of a case having a speaker mesh module according to claim 6 , wherein the speaker mesh module further comprises an adhesive film disposed between the speaker mesh film and the base, the adhesive film comprising a opening corresponding to the opening in the base, wherein the combination member is formed with a combining part fastened to the adhesive film in the recess.

9. The manufacturing method of a case having a speaker mesh module according to claim 6 , wherein the speaker mesh module includes a buckle part composed of at least one groove, the combining part is composed of at least one protrusion extended from the combination member, and the protrusion and the groove are mutually fastened.

10. The manufacturing method of a case having a speaker mesh module according to claim 9 , wherein the quantity of grooves is plural, and each of the grooves is composed of a slot inwardly formed from the outer periphery of the speaker mesh module.

11. The manufacturing method of a case having a speaker mesh module according to claim 9 , wherein the quantity of grooves is plural, and each of the grooves is composed of a hollow slot penetrating two surfaces of the speaker mesh module.

12. The manufacturing method of a case having a speaker mesh module according to claim 6 , wherein speaker mesh film is waterproof.
