Abstract: A digital TV receiving device includes a control circuit board and a TV tuner; a built-in signal receiver in the digital TV receiving device receives AV signals transmitted by digital TV broadcasting system; the TV turner decodes and modulates those AV signals, and then transmits modulated/restored digital signals to an externally connected information host to output for presentation.

Abstract: A screen transportation device has a frame; a carrier being movable between a first position and a second position; a linkage having one end pivoted with a first connecting part on the carrier and another end slid along and pivoted with the frame; and a guiding device pivoted with a second connecting part on the carrier and being movable in the frame; wherein the carrier is able to pivot with the second connecting part on the carrier between a first angle and a second angle.

Abstract: An anti-resonant structure for speakers includes a resonant structure which has a housing compartment, at least one elastic element located in the housing compartment that has one end fastening to the resonant structure and another end coupling with a speaker, and at least one buffer element located between the resonant structure and the elastic element to serve as a buffer interface to prevent the speaker from hitting due to elastic element and the resonant structure. The speaker is the element that generates vibration. The elastic element has an elastic section to absorb the vibration energy generated by the speaker to prevent the resonant structure from generating unwanted resonance and noises, and prevent electronic elements from being damaged by the resonant effect.

Abstract: An attachable frame for flat display panels includes a flat display panel, a main structure, a bracing structure, a front frame and a rear frame. The main structure and the bracing structure provide bracing and steady support for the entire body. The front frame and the rear frame provide a desired appealing for the entire body. The main structure, bracing structure, front frame and rear frame are separable elements and are designed according to the dimension of the flat display panel. They may be assembled to form the exterior of the flat display panel, and become attachable to the flat display panel.
