发明名称 Multimedia computer keyboard
摘要 A multimedia computer keyboard is provided having one or more high fidelity, diaphragm-type speakers mounted within the keyboard. Mono or stereophonic wiring to each speaker is achieved using existing keyboard cable extending from the keyboard to a keyboard connector arranged upon a host computer. A terminal at the end of the keyboard cable can plug directly into the keyboard connector, such that the terminal can receive an audio output signal generated from a sound card placed within the computer. Accordingly, audio output can be sent to the computer keyboard as an integrated system in order to achieve multimedia function.
