  • Publication number: 20090169045
    Abstract: A display device includes a display panel, a frame, and a speaker unit. The frame encloses a periphery of the display panel. The speaker unit includes a speaker housing and a speaker assembly. The speaker housing includes first and second housing parts. The first housing part is connected to the frame, has a front opening, and is formed with a hole. The second housing part is mounted on a rear side of the display panel, defines a chamber, and has an open end. The open end of the second housing part is connected to the first housing part such that the chamber in the second housing part is in spatial communication with the front opening in the first housing part through the hole. The speaker assembly is disposed in the chamber in the second housing part and is coupled electrically to the display panel.

  • Publication number: 20070206123
    Abstract: A liquid crystal television includes a base unit, a rear cover, a support member, an audiovisual circuit unit, and an audiovisual output unit. The rear cover is coupled to and is disposed on top of the base unit, and has an inner cover surface that confines a cover space. The support member is received in the cover space and is disposed to lie against the inner cover surface of the rear cover. The support member includes a main wall, and a flange extending from a periphery of the main wall and cooperating with the main wall to define a compartment for mounting of the audiovisual circuit unit therein. The audiovisual output unit is disposed forwardly of the audiovisual circuit unit, is secured to the flange of the support member, and includes a display panel and a speaker that are connected electrically to the audiovisual circuit unit.
