Abstract

An electronic apparatus includes an electronic-apparatus housing provided with a sound release hole, a speaker unit housed in the electronic-apparatus housing and facing the sound release hole, a grille body made of a conductive material, configured to allow sound to pass therethrough, and having a plate-like shape that is of sufficient size to cover the sound release hole, a frame made of an insulating material and detachably attached to the electronic-apparatus housing while supporting the grille body, such that the grille body covers the sound release hole, a cushion member provided on the frame and having elasticity and conductivity that allows the cushion member to be electrically continuous with the grille body, and a conductive member grounded inside the electronic-apparatus housing and, when the frame is attached to the electronic-apparatus housing, becoming electrically continuous with the grille body through the cushion member.

Claims

1. An electronic apparatus comprising:

an electronic-apparatus housing provided with a sound release hole;

a speaker unit housed in the electronic-apparatus housing and facing the sound release hole;

a grille body made of a conductive material, configured to allow sound to pass therethrough, and having a plate-like shape that is of sufficient size to cover the sound release hole;

a frame made of an insulating material and detachably attached to the electronic-apparatus housing while supporting the grille body, such that the grille body covers the sound release hole;

a cushion member provided on the frame and having elasticity and conductivity that allows the cushion member to be electrically continuous with the grille body; and

a conductive member grounded inside the electronic-apparatus housing and, when the frame is attached to the electronic-apparatus housing, becoming electrically continuous with the grille body through the cushion member.

2. The electronic apparatus according to claim 1, further comprising a display panel held in the electronic-apparatus housing,

wherein the speaker unit and the grille body are positioned inside the electronic-apparatus housing and outside the display panel.

3. The electronic apparatus according to claim 1, wherein the speaker unit is housed in a speaker box, the speaker box being attached to the electronic-apparatus housing, whereby the speaker box is included in the electronic-apparatus housing.

4. The electronic apparatus according to claim 1, wherein the conductive member has an elongated shape with a portion thereof in a longitudinal direction forming a rod having a circular cross section and the rest forming an external thread provided coaxially with the rod and having a smaller diameter than the rod, the rod having at a tip thereof a fitting hole extending coaxially with the rod, the fitting hole being capable of receiving a hexagonal wrench.

5. The electronic apparatus according to claim 1,

wherein the grille body includes

a plate member configured to cover the sound release hole;

and

a connection tab projecting, in a state where the plate member covers the sound release hole, from the plate member toward a side on which the speaker unit is provided, and

wherein the cushion member and the grille body become electrically continuous with each other when the connection tab comes into contact with the cushion member.

6. The electronic apparatus according to claim 1,

wherein a front face of the grille body is exposed frontward on a front face of the electronic-apparatus housing,

wherein the grille body is supported at a rear face thereof by the frame,

wherein the frame has a receiving wall member having a rectangular frame-like shape and projecting rearward, and

wherein the cushion member is received by the receiving wall member.
