Abstract

An electronic device including a display panel, a protection layer, and a sound broadcasting element is provided. The protection layer is disposed on the display panel. The sound broadcasting element and the display panel are both located below the protection layer, and the sound broadcasting element contacts the protection layer.

First claim

What is claimed is:

1. An electronic device comprising:
a display panel;
a protection layer disposed on the display panel; and
a sound broadcasting element disposed adjacent to the protection layer and contacting the protection layer,
wherein the sound broadcasting element comprises a piezoelectric component and a connection component, the connection component is connected between the piezoelectric component and the protection layer, the connection component is located on a side of the display panel, a distance between the piezoelectric component and the display panel is in a range of 0.1 mm to 5 cm, and a back surface of the display panel is located between the piezoelectric component and the protection layer.

2. The electronic device as claimed in claim 1 , wherein the display panel and the sound broadcasting element contact an inner surface of the protection layer.

3. The electronic device as claimed in claim 1 , wherein the sound broadcasting element contacts a side surface of the display panel.

4. The electronic device as claimed in claim 1 , wherein an air gap exists between the sound broadcasting element and the display panel.

5. The electronic device as claimed in claim 1 , wherein the piezoelectric component comprises a piezoelectric portion and a conductive portion overlapping the piezoelectric portion.

6. The electronic device as claimed in claim 5 , wherein the piezoelectric portion has at least one opening.

7. The electronic device as claimed in claim 6 , wherein a material of the connection component comprises a conductive material or a buffer material.
