DETAILED DESCRIPTION
FIGS. 1-3 illustrate a display 100 of a first exemplary embodiment. The display 100 includes a display panel 10 and a speaker 20.
The display panel 10 is used for displaying images according to received image signals. The display panel 10 includes a display surface 11. In the first embodiment, the display panel 10 is a liquid crystal display, and includes a horizontal polarizer, a color filter, a liquid crystal layer, a thin film transistor, a vertical polarizer, a driving circuit board, a diffusion sheet, and a backlight module.
The speaker 20 includes a hollow glass housing 21 and a number of vibration exciters 26. The glass housing 21 is fixed on the display panel 10. The glass housing 21 defines a hermetical receiving cavity 23. The glass housing 21 is substantially rectangular frame-shaped, and includes a front wall 21a, a back wall 21b, an outer wall 21c, and an inner wall 21d. The front wall 21a is adjacent to the display surface 11. The back wall 21b is opposite to the front wall 21a. The outer wall 21c is opposite to the inner wall 21d. Both of the outer wall 21c and the inner wall 21d are connected to the front wall 21a and the back wall 21b. 
The glass housing 21 has a through hole 24 passing through the front wall 21a and the back wall 21b. The through hole 24 fits with the display panel 10, and thus the glass housing 21 surrounds the display panel 10. The outer wall 21d is away from the display panel 10. The inner wall 21d is in contact with the display panel 10.
The vibration exciters 26 are received in the receiving cavity 23, and are equidistantly spaced. The vibration exciters 26 are attached to the glass housing 21, and are used for driving the glass housing 21 to vibrate, thus generating sound waves. The vibration exciters 26 may be products HIAX25C10-8/HS or HiHX14CO2-08 of HiWave Technologies PLC.
In the first embodiment, the vibration exciters 26 are attached to an inner surface 22c of the outer wall 21c, and the inner surface 22c of the outer wall 21c is exposed in the receiving cavity 23. In other embodiments, the vibration exciters 26 can be attached to an inner surface 22a of the front wall 21a or an inner surface 22b of the back wall 21b, and the inner surface 22a of the front wall 21a and an inner surface 22b of the back wall 21b are exposed in the receiving cavity 23.
In use, the display panel 10 displays images according to the received image signals, and the vibration exciters 26 drive the glass housing 21 to vibrate, and thus to generate the sound waves.
FIGS. 4-5 show a display 200 according to a second exemplary embodiment. The differences between the display 200 and the display 100 are that, a particular surface 2210 of the glass housing 221 defines a receiving recess 224 rather than the through hole 24. The receiving recess 224 is used for receiving the display panel 210, and the display surface 211 is exposed from the receiving recess 224. The display surface 211 and the particular surface 2210 are at a same planar surface.
The glass housing 221 has a hermetical receiving recess 223, and includes a front wall 221a, a back wall 221b, an outer wall 221c, and an inner wall 221d. The front wall 221a, the outer wall 221c, and an inner wall 221d are substantially rectangular frame-shaped, and the back wall 221b is substantially a planar surface. The front wall 221a is adjacent to the display panel 210. The back wall 221b is opposite to the front wall 221a. The outer wall 221c is opposite to the inner wall 221d, and is connected to the front wall 221a and the back wall 221b. The inner wall 221d is connected to the front wall 221a. The inner wall 221d is in contact with the display panel 210, and is received in the receiving recess 223. The outer wall 221c is away from the display panel 210.
In the second embodiment, the vibration exciters 226 are attached to an inner surface 221e of the outer wall 221c and an inner surface 221f of the back wall 221b. The inner surface 221e of the outer wall 221c and the inner surface 221f of the back wall 221b are exposed in the receiving cavity 223. The inner surface 221e of the outer wall 221c is connected to the inner surface 221f of the back wall 221b. In other embodiments, the vibration exciters 226 are attached to the inner surface 221e of the outer wall 221c or the inner surface 221f of the back wall 221b. 
FIG. 6 shows a display 300 according to a third exemplary embodiment. The differences between the display 300 and the display 100 are that, the display panel 310 has a display surface 311 and a back surface 312 opposite to the display surface 311. The glass housing 321 is fixed on the back surface 312. The glass housing 321 defines a hermetical receiving cavity 323, and has a front wall 321a, a back wall 321b, and four sidewalls 321c. The front wall 321a is in contact with the display panel 310. The back wall 321b is opposite to the front wall 321a, and is away from the display panel 310. The four sidewalls 321c are connected to the front wall 321a and the back wall 321b. In the third embodiment, the vibration exciters 326 are attached to an inner surface 321e of the back wall 321b and four inner surfaces 321f of the four sidewalls 321c. The inner surface 321e of the back wall 321b and four inner surfaces 321f of the four sidewalls 321c are exposed in the receiving cavity 323, and the inner surface 321e of the back wall 321b is connected to the inner surfaces 321f of the four sidewalls 321c. 
In other embodiments, the vibration exciters 326 can be only attached to at least one of the inner surface 321e of the back surface 321b or the four inner surfaces 321f of the four sidewalls 321c, or the vibration exciters 326 can be only attached to the four inner surfaces 321f of the four sidewalls 321c. 
By employing the display with the speaker, an external speaker connected to the display can be omitted, which is very convenient.
It will be understood that the above particular embodiments are shown and described by way of illustration only. The principles and the features of the present disclosure may be employed in various and numerous embodiments thereof without departing from the scope of the disclosure as claimed. The above-described embodiments illustrate the scope of the disclosure but do not restrict the scope of the disclosure.
