Abstract: A digital audio/video playing device includes a touch control board, a plurality of switch units disposed outside a perimeter of the touch control board, and a support plate disposed on the touch control board and switch units. The support plate includes a central portion, an intermediary portion ringing the central portion, and an outer portion ringing the intermediary portion. The central portion and the outer portion are thicker than the intermediary portion such that the intermediary portion is recessed relative to the central portion and the outer portion. The intermediary portion is disposed directly facing the touch control board. A plurality of depressible tabs are formed in the outer portion, each depressible tab corresponding to and directly facing a corresponding one of the switch units. A surface film is arranged over and covering the support plate such that a raised-recessed-raised configuration is formed.

Abstract: A karaoke device is included within an enclosure and having a voice pickup element integrated into the enclosure, the voice pickup element for converting sound waves into an electrical signal. An audio input signal passes into the enclosure and connects with an electronic circuit for amplifying the electrical signal, for controlling the amplitude of the electrical signal and for mixing the electrical signal and the audio input signal into a mixed audio signal which passes out of the enclosure. A video input signal passes into the enclosure and directly connects to a video output signal that passes out of the enclosure.

Abstract: A mobile communication apparatus with multimedia audio/video functions includes an upper casing, a lower casing movably connected to a backside of the upper casing, and an audio/video capturing module mounted on one end of the upper casing. The upper and lower casings are engaged with each other, and the audio/video capturing module is used to receive and sample an image and/or a sound source within an area, and then output an audio/video signal which is sent to a screen display mounted on a surface of the upper casing adjacent to the audio/video capturing module for displaying the image. The upper casing further includes a control circuit therein for driving an optical disk read/write module installed on the lower casing, such that the optical disk read/write module can process the audio/video signal and execute a data burning operation for writing the audio/video signal into an optical disk in the optical disk read/write module.
