## Abstract

A passive sounding device integrated into a flat panel display includes a glass diaphragm having a first surface for forming a light-emitting array of the flat-panel display thereon, a suspension edge, and a frame, wherein the glass diaphragm is tightly sealed with the frame through the suspension edge to form an airtight space in the frame, and the glass diaphragm vibrates and emits sound in response to the pressure of the sound waves generated by an active sounding device.

## Claims

### Claim 1

A passive sounding device integrated into a flat panel display, said device comprising:
a glass diaphragm having a first surface, wherein a light emitting array is formed on said first surface; and
a suspension device; and
a frame body, wherein said glass diaphragm is tightly sealed with said frame body through said suspension device to form an airtight space in said frame body, and said glass diaphragm vibrates and emits sound in response to the pressure of the sound waves generated by an active sounding device.

### Claim 2 (depends on 1)

The passive sounding device integrated into a flat panel display of claim 1, further including a metal frame been integrated with said suspension device for adjusting counterweight responded to said pressure of said sound waves to extend bass of said passive sounding device.

### Claim 3 (depends on 2)

The passive sounding device integrated into a flat panel display of claim 2, wherein said suspension device is made of rubber.

### Claim 4 (depends on 1)

The passive sounding device integrated into a flat panel display of claim 1, wherein said first surface faces outward of opening of said frame body.

### Claim 5 (depends on 1)

The passive sounding device integrated into a flat panel display of claim 1, wherein said flat panel display is TFT-LCD, OLED, LED, mini-LED or micro-LED display panel.

### Claim 6 (depends on 1)

The passive sounding device integrated into a flat panel display of claim 1, wherein said active sounding device is a speaker.

### Claim 7 (depends on 5)

The passive sounding device integrated into a flat panel display of claim 5, wherein said display panel is used as a passive radiator to adjust counterweight responded to said pressure of said sound waves to extend bass of said passive sounding device.

### Claim 8 (depends on 6)

The passive sounding device integrated into a flat panel display of claim 6, wherein said speaker is disposed inside said frame body or coupled to said frame body.

### Claim 9 (depends on 8)

The passive sounding device integrated into a flat panel display of claim 8, wherein said speaker coupled to said frame body is disposed inside a cavity interconnected with said frame body.

### Claim 10 (depends on 9)

The passive sounding device integrated into a flat panel display of claim 9, wherein said cavity interconnected with an accommodation space of said frame body to form a composite sealed space.

### Claim 11 (depends on 1)

The passive sounding device integrated into a flat panel display of claim 1, wherein said glass diaphragm further including an adhesive film attached thereon.

### Claim 12 (depends on 11)

The passive sounding device integrated into a flat panel display of claim 11, wherein said adhesive film is selected from polyethylene terephthalate (PET), polyimide (PI) or the likes.

### Claim 13 (depends on 2)

The passive sounding device integrated into a flat panel display of claim 2, wherein said metal frame is made of aluminum or aluminum alloy.
