## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a case structure, especially to a case having a speaker mesh module and a manufacturing method thereof.
2. Description of Related Art
A portable electronic device such as a notebook computer, a mobile phone, a watch, a walkman, a camera or a personal digital assistance has become a must-have item in our lives. As such, the portable electronic device might be operated in various environments such as shopping malls, party scenes, mountains, rivers or seashores when the user takes the portable electronic device with him/her. Accordingly, the portable electronic device has to be provided with excellent dustproof characteristic and waterproof effects.
As present, the means for enabling the portable electronic device to be provided with the dustproof characteristic and waterproof effects is to directly design a dustproof and waterproof case on the portable electronic device, or to store the portable electronic device in an external sealed case. For allowing the speaker of the portable electronic device to smoothly transmit sound to the exterior and avoiding the problems of poor sound quality, sound distortion and sound breaking. The case of the portable electronic device or the external sealed case is formed with an opening and a waterproof air-permeable film, wherein the opening is formed corresponding to the speaker and the waterproof air-permeable film is adhered on the case and served to seal the opening.
However, the arrangement of directly adhering the waterproof air-permeable film on the case has following disadvantages. First, the waterproof performance of the case of the portable electronic device or the external sealed case is determined by the adhesion status between the waterproof air-permeable film and the case. As such, if the adhesion status between the waterproof air-permeable film and the case performs poorly, the waterproof characteristics of the case of the portable electronic device or the external sealed case would be no loner provided. Second the waterproof air-permeable film detaches from the case easily when the case of the portable electronic device or the external sealed case is subject to a friction force or a shaking force, thereby causing the waterproof performance of the case of the portable electronic device or the external sealed case to fail.
In view of what has been disclosed above, the applicant of the present invention has devoted himself for improving the above-mentioned disadvantages.
SUMMARY OF THE INVENTION
The present invention is to provide a case having a speaker mesh module and a manufacturing method thereof, in which a combination member is secured on a base through a filling port with an injection molding means and served to cover the speaker mesh module, so the speaker mesh module is able to be sealed in an opening with a means other than adhering, thereby allowing the case to be provided with a stable and excellent waterproof performance.
Accordingly, the present invention provides a case having a speaker mesh module, which includes:
a base, formed with an opening and a filling port;
a speaker mesh module, correspondingly placed in the opening, and formed with a buckle part and a sound output part; and
a combination member, secured on the base through the filling port with an injection molding means and served to cover the speaker mesh module, and formed with a combining part and a penetrated hole, wherein the combining part and buckle part are mutually fastened and the penetrated hole is formed corresponding to the sound output part.
Accordingly, the present invention provides a manufacturing method of a case having a speaker mesh module, which includes the steps of:
step a) providing a base, wherein the base is formed with an opening and a filling port;
step b) providing a speaker mesh module;
step c) placing the speaker mesh module in the opening;
step d) providing an injection device and a molding device, wherein the molding device is disposed corresponding to the base and the speaker mesh module; and
step e) the injection device injecting a forming material through the filling port to the molding device so as to form a combination member, thereby allowing the combination member to be secured on the base and served to cover the speaker mesh module.
Advantages achieved by the present invention are as follows:
First, 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 thereby allowing the case to be provided with effects of dustproof and waterproof, and a speaker stored in the case is enabled to smoothly transmit sound to the exterior through the opening and the speaker mesh module.
Second, the base, the speaker mesh module and the combination member can be tightly matched through the injection molding means; accordingly, the case can be composed of simple components for allowing the case to be provided with effects of dustproof and waterproof, so the case has advantages of simple in components and easy in assembly.
Third, the buckle part is composed of grooves formed on the speaker mesh module; in the process of the injection device injecting the forming material through the filling port to the molding device, the grooves allow the forming material to flow into the space for being combined with the base so as to form a riveting force; when the forming material is formed as the combination member, the combination member is enabled to be tightly combined with the base with the injection molding means.
Fourth, the combination member is able to position the speaker mesh module with the injection molding means, thereby allowing the speaker mesh module to be stably placed and sealed in the opening; accordingly, the speaker mesh module is able to be sealed in the opening with a means other than adhering, thereby preventing the case from having poor dustproof and waterproof performance due to the insufficient adhesion.
Fifth, when the case is subject to a friction force or a shaking force, because the speaker mesh module is covered by the combination member, the speaker mesh module is still able to be stably placed and sealed in the opening, so the speaker mesh module and the base can still be tightly combined thereby preventing water from permeating and ensuring the structural stability, thereby allowing the case of the present invention to be provided with excellent dustproof and waterproof performance.
Sixth, the speaker mesh module is formed with a waterproof speaker mesh film and an adhesive film; the adhesive film is adhered between the waterproof speaker mesh film and the base thereby enabling the speaker mesh module to be placed in the opening, so the waterproof speaker mesh film is able to be tightly adhered on the base through the adhesive film, and the speaker mesh module can be stably placed and sealed in the opening, thereby further enhancing the dustproof and waterproof performance of the case.
