Abstract
(EN)
A multimedia computer keyboard (10) that is adaptable to new or existing computer systems. The computer keyboard has built-in full range stereo speakers (12) with a control panel (14-20) located above the standard alphanumeric and function key pads. The computer keyboard also has external headphone and microphone jacks (26, 24) with interrupt circuitry. The standard alphanumeric and function key pad circuitry and the audio circuitry are maintained as separate circuit components within the multimedia computer keyboard housing. Individual component cables are combined into a signal cable (30) that connects the multimedia computer keyboard to the computer CPU terminal. Also, floppy disk drive, CD-ROM disk drive and telecommunications components may be incorporated into said multimedia computer keyboard system.
