A slide-in structure () inside a cradle set () for accommodating a personal digital assistant (PDA) module () is disclosed. The slide-in structure comprises a base plate (), a sliding stand () and a pushing arm (). A connector () of the cradle set is fastened to the sliding stand via a circuit board (). The base plate has a pair of sidewalls () and two sliding grooves () located on of the sidewalls. The two ends of the sliding stand are inserted into the respective sliding grooves so that the sliding stand is free to move relative to the sliding grooves. The pushing arm is in contact with the sliding stand. The pushing arm resiliently pushes the sliding stand to one side of the sliding grooves and provides a buffering force when the PDA module engages with/disengages from the connector in the cradle set.

A button apparatus with a speaker () has a frame (), a speaker (), a flexible PCB (), a metal dome (), a rubber layer (), and an operating button (). The frame has a cavity () and the speaker is securely received in the cavity. The flexible PCB is located on the frame. The metal dome is located on the flexible PCB, and adapted to electrically connect with the flexible PCB. The rubber layer is located on the flexible PCB. The rubber layer has a protrusion () to press the metal dome so that the metal dome is electrically coupling to the flexible PCB. The operating button is located on the rubber layer. The button is adapted to press the protrusion, which in turn presses the metal dome.

Button apparatus with a speaker

In a method and apparatus for generating musical accompaniment signals corresponding to a musical program, there is provided a recording medium which has an audio storage unit and a lyric storage unit separate from the audio storage unit. The audio storage unit and the lyric storage unit respectively have a plurality of audio music data and a plurality of lyric data corresponding to a plurality of the musical programs stored therein. The lyric data include encoded text data and timing information. In operation, the audio music data and the lyric data corresponding to a selected one of the musical programs are retrieved from the recording medium. The encoded text data and timing information retrieved from the recording medium are decoded to obtain decoded data, and bitmap data are then generated from the decoded data. The bitmap data are synchronized with the audio music data retrieved from the recording medium in accordance with the timing information. The audio music data retrieved from the recording medium are provided to a sound card to obtain an audio output. The bitmap data are provided to a VGA card to obtain a video signal.

In a method and apparatus for generating audio-visual musical accompaniment signals corresponding to a musical program, there is provided a recording medium which has an audio storage unit, a lyric storage unit and a video storage unit separate from the audio storage unit and the lyric storage unit. The audio storage unit and the lyric storage unit respectively have a plurality of audio music data and a plurality of lyric data corresponding to a plurality of the musical programs stored therein. The video storage unit has a plurality of video segments to be commonly shared by the plurality of the musical programs stored therein. In operation, the audio music data and the lyric data corresponding to a selected one of the musical programs are retrieved from the recording medium, while at least a section of the video segments are retrieved from the recording medium in an order. The audio music data retrieved from the recording medium is converted into an audio output, and the lyric data and the sections of the video segments retrieved from the recording medium are combined to obtain a video output. The audio and video outputs constitute the musical accompaniment signals corresponding to the selected one of the musical programs.
