## Abstract

A speaker fastening mechanism includes a first fastening component installed inside an audio device, a second fastening component installed inside the audio device and disposed on a side of the first fastening component, a speaker unit whereon a first fixing part and a second fixing part are formed, a first elastic component wedged in the first fixing part and fastened inside the first fastening component, and a second elastic component wedged in the second fixing part and fastened inside the second fastening component in a rotating manner after the first elastic component is fastened inside the first fastening component.

## Claims

### Claim 1

A speaker fastening mechanism comprising:
a first fastening component having a first hole and a first breach formed on a side of the first hole, the first fastening component being installed inside an audio device;
a second fastening component having a second hole and a second breach formed on a side of the second hole, a direction of the first breach being substantially perpendicular to a direction of the second breach, and the second fastening component being installed inside the audio device and disposed on a side of the first fastening component;
a speaker unit, whereon a first fixing part and a second fixing part are formed;
a first elastic component wedged in the first fixing part and fastened inside the first hole of the first fastening component; and
a second elastic component wedged in the second fixing part and fastened inside the second hole of the second fastening component in a rotating manner after the first elastic component is fastened inside the first fastening component, for biaxially constraining the speaker unit with the first elastic component.

### Claim 2 (depends on 1)

The speaker fastening mechanism of claim 1, wherein a protrusion is disposed on a side of the first breach of the first fastening component for constraining the first elastic component inside the first hole.

### Claim 3 (depends on 1)

The speaker fastening mechanism of claim 1, wherein a protrusion is disposed on a side of the second breach of the second fastening component for constraining the second elastic component inside the second hole.

### Claim 4 (depends on 1)

The speaker fastening mechanism of claim 1, wherein the first elastic component comprises:
a first washer installed on a side of the first fixing part when the first elastic component wedges inside the first fixing part of the speaker unit;
a first gasket for clamping the speaker unit with the first washer; and
a second gasket for clamping the first fastening component with the first gasket.

### Claim 5 (depends on 4)

The speaker fastening mechanism of claim 4, wherein the first washer, the first gasket, and the second gasket are integrated monolithically.

### Claim 6 (depends on 1)

The speaker fastening mechanism of claim 1, wherein the second elastic component comprises:
a second washer installed on a side of the second fixing part when the second elastic component wedges inside the second fixing part of the speaker unit;
a third gasket for clamping the speaker unit with the second washer; and
a fourth gasket for clamping the second fastening component with the third gasket.

### Claim 7 (depends on 6)

The speaker fastening mechanism of claim 6, wherein the second washer, the third gasket, and the fourth gasket are integrated monolithically.

### Claim 8 (depends on 1)

The speaker fastening mechanism of claim 1, wherein the first fixing part and the second fixing part are openings respectively.
