Abstract

With a waterproof structure for the space between a first case and a diaphragm doubling as a display panel provided facing the first case, a first resilient member is integrally formed at a surface of the diaphragm facing the first case, and the first resilient member is press-fitted into a groove formed in a surface of the first case facing the diaphragm side.

Claims (19)

1. A waterproof structure comprising:

a first case;

a diaphragm doubling as a display panel provided corresponding to the first case;

a second case having an opening within where the diaphragm is disposed so that a surface of the diaphragm and a surface of the second case are substantially in the same plane, covering the first case; and

a first resilient member integrally formed at a surface of the diaphragm facing the first case, wherein

the first resilient member is press-fitted into a groove formed in a surface of the first case facing the diaphragm side.

2. The waterproof structure according to claim 1 , further comprising a center case housed within a space formed between the first case and the diaphragm, and wherein the first resilient member is fixed by the second case and is disposed between the diaphragm and the center case.

3. The waterproof structure according to claim 1 , wherein the diaphragm and the first case are fixed using stepped screws via a second resilient member.

4. A waterproof structure comprising:

a first case;

a diaphragm doubling as a display panel provided corresponding to the first case; a second case having an opening within where the diaphragm is disposed so that a surface of the diaphragm and a surface of the second case are substantially in the same plane, covering the first case; and

a first resilient member formed integrally via a film at a surface of the diaphragm facing the first case, wherein

the first resilient member is press-fitted into a groove formed at a surface of the first case facing the diaphragm.

5. The waterproof structure according to claim 4 , wherein the film is a flexible wiring substrate.

6. The waterproof structure according to claim 4 , further comprising a center case housed within a space formed between the first case and the diaphragm, and wherein

the first resilient member is fixed by the second case and is disposed between the diaphragm and the center case.

7. The waterproof structure according to claim 4 , wherein the diaphragm and the first case are fixed using stepped screws via a second resilient member.

8. An electronic equipment equipped with the waterproof structure according to claim 1 .

9. An electronic equipment equipped with the waterproof structure according to claim 4 .
