BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to a display device and, more particularly, to a display device capable of enhancing sound effect for a woofer effectively.

2. Description of the Prior Art

Currently, lots of display devices are equipped with a woofer for outputting bass effect. The woofer of a conventional display device is disposed in the back of a casing and the sound holes corresponding to the woofer are orientated towards a back side or a bottom side, such that the woofer outputs a bass effect towards the back side or bottom side of the display device. In general, some objects, such as wall, partition, etc. may exist in back of the display device, such that the bass effect outputted by the woofer may be easily blocked by the object in back of the display device. Consequently, the sound effect generated by the woofer is affected.

SUMMARY OF THE INVENTION

An objective of the invention is to provide a display device capable of enhancing sound effect for a woofer effectively, so as to solve the aforesaid problems.

According to an embodiment of the invention, a display device comprises a casing, a display module and a woofer. The casing comprises a back cover. A top side of the back cover has a plurality of sound holes formed thereon. A wall structure extends from an inner surface of the back cover. An opening of the wall structure communicates with the sound holes. The display module is disposed in the casing. The woofer is disposed in the casing and located between the display module and the back cover. The wall structure encloses the woofer to guide a sound outputted by the woofer to the sound holes through the opening.

As mentioned in the above, the invention forms the sound holes on the top side of the back cover of the display device and forms the wall structure on the inner surface of the back cover. After assembling the display device, the wall structure of the back cover encloses the woofer, such that the sound outputted by the woofer is guided to the sound holes through the opening of the wall structure, so as to output the sound from the top side of the back cover. In general, there may be few, even no, objects located at the top side of the display device. Accordingly, the sound outputted from the top side is beneficial to be received by a user. Therefore, the invention can enhance sound effect for the woofer effectively.

DETAILED DESCRIPTION

Referring toFIGS. 1 to 6,FIG. 1is a front perspective view illustrating a display device1according to an embodiment of the invention,FIG. 2is a rear perspective view illustrating the display device1shown inFIG. 1,FIG. 3is an exploded view illustrating the display device1shown inFIG. 2,FIG. 4is a perspective view illustrating the back cover102shown inFIG. 3from another viewing angle,FIG. 5is a perspective view illustrating the woofer14shown inFIG. 3being fixed to the back cover102, andFIG. 6is a perspective view illustrating the woofer14and the back cover102shown inFIG. 5from another viewing angle.

As shown inFIGS. 1 to 3, the display device1comprises a casing10, a display module12, a woofer14and a plurality of speakers16. In practical applications, the display device1may be a television, a computer screen, an electronic signage or other electronic devices with display function, and the display module12may be a liquid crystal display panel, a plasma display panel, an organic light emitting diode display panel or other display panels.

In this embodiment, the casing10may comprise a front bezel100and a back cover102, wherein the front bezel100is connected to the back cover102. The display module12is disposed in the casing10and fixed to the front bezel100. The woofer14is disposed in the casing10and located between the display module12and the back cover102. In this embodiment, the woofer14may be fixed to the back cover102by fixing members18(e.g. screws), as shown inFIGS. 5and6. The speakers16are disposed on the front bezel100. In this embodiment, the display device1may comprise two speakers16disposed on lower opposite sides of the front bezel100, as shown inFIG. 1. Accordingly, the woofer14may cooperate with the two speakers16to form 2.1-channel.

It should be noted that the number and position of the speakers16may be determined according to practical applications, so the invention is not limited to the embodiment shown in the figures. For example, the invention may also dispose three, five or seven speakers16on the front bezel100to cooperate with the woofer14to form 3.1-channel, 5.1-channel or 7.1-channel.

As shown inFIG. 2, a top side104of the back cover102has a plurality of sound holes1020formed thereon, wherein the top side104of the back cover102represents an upper side of the back cover102orientated towards the sky. In this embodiment, each of the sound holes1020has an inclined surface1022and the inclined surface1022inclines to the top side104of the back cover102. Furthermore, as shown inFIG. 4, a wall structure1026extends from an inner surface1024of the back cover102and an opening1028of the wall structure1026communicates with the sound holes1020.

As shown inFIGS. 5 and 6, after the woofer14is fixed to the back cover102, the wall structure1026encloses the woofer14. Accordingly, when the woofer14outputs a sound, the wall structure14guides the sound outputted by the woofer14to the sound holes1020through the opening1028, so as to output the sound from the top side104of the back cover102. In general, there may be few, even no, objects located at the top side104of the display device1. Accordingly, the sound outputted from the top side104is beneficial to be received by a user. Therefore, the invention can enhance sound effect for the woofer14effectively. Furthermore, since each of the sound holes1020has the inclined surface1022inclining to the top side104of the back cover102, the sound outputted by the woofer14can be guided to the top side104through the inclined surface1022of the sound hole1020, so as to further enhance sound effect for the woofer14. It should be noted that the display device1may further comprise a sealing material disposed between the wall structure1026and the woofer14. For example, the invention may dispose a sealing sponge or other sealing materials between the wall structure1026and the woofer14, so as to ensure that a closed space is formed between the woofer14and the sound holes1020.

Referring toFIGS. 7 and 8,FIG. 7is a rear view illustrating a display device1′ according to another embodiment of the invention andFIG. 8is a rear view illustrating a display device1′ according to another embodiment of the invention. As shown inFIGS. 7 and 8, the invention may dispose the woofer14at any position in the casing10and the wall structure1026of the back cover102may extend from the sound holes1020to the woofer14, so as to guide the sound outputted by the woofer14to the sound holes1020by the wall structure1026.

As mentioned in the above, the invention forms the sound holes on the top side of the back cover of the display device and forms the wall structure on the inner surface of the back cover. After assembling the display device, the wall structure of the back cover encloses the woofer, such that the sound outputted by the woofer is guided to the sound holes through the opening of the wall structure, so as to output the sound from the top side of the back cover. In general, there may be few, even no, objects located at the top side of the display device. Accordingly, the sound outputted from the top side is beneficial to be received by a user. Therefore, the invention can enhance sound effect for the woofer effectively.
