Description:
FIELD OF THE INVENTION 
     The present invention relates to a flat panel display, and more particularly to a flat panel display with sliding loudspeaker structure. 
     DESCRIPTION OF THE RELATED ART 
     With the rapid development in scientific technologies, human life quality is improved consequently. The conventional big-size and expensive Cathode Ray Tube (CRT) displays have been gradually replaced by today&#39;s light weight and thin liquid crystal displays (LCDs). Among others, portable LCDs allow users to enjoy good audio-visual experience at any time and any place, and are therefore most widely welcomed and accepted. 
     Conventionally, a flat panel display, such as an LCD television, is provided with two external or internal loudspeaker bodies to achieve the sound effect thereof. However, in the case of internal loudspeaker bodies, since only very limited space is available inside the flat panel display for forming a sound field, the sound quality that can be produced by such loudspeaker body is relatively poor. Further, as the installation of such loudspeaker bodies, a user is not allowed to freely adjust the position and the direction of the loudspeaker bodies according to the user&#39;s need. Even though the loudspeaker can provide sound, but the quality of the sound is not satisfied. 
     On the other hand, while the external loudspeakers can be freely adjusted in position, they are usually located at two lateral sides of the flat panel display, so they will inevitably affect the appearance of the flat panel display. Moreover, when people wish to bring the flat panel display to the outdoors, it is not convenient for user to bring the external loudspeakers since they must be additionally packed and large space would be occupied. Besides, while these equipments are in use or in storage, their wires tend to become tangled and messy, which causes articles to drop or trip over. Further, the user has to search for a usable socket to use. 
     SUMMARY OF THE INVENTION 
     In view of this problem, one objective of the present invention is therefore to provide a flat panel display with sliding loudspeaker structure, so as to overcome the problems of an immovable loudspeaker and angularly non-adjustable loudspeaker sound field on a conventional display.
