A keyboard structure primarily consists of a keyboard body which contains an amplification circuit connected with a microphone socket, a headphone socket and trumpets, a USB socket, an IEEE1394 socket and jacks located at proper positions of the keyboard. The keyboard structure can be provided for listening to music or voice transmitted by a computer through the headphone or trumpets, and for constituting a function of dialoging through the microphone. Whereas, the jacks located at the keyboard body can be used for inserting a device such as a snake-lamp or fan, thereby improving a value of practicability of the keyboard.
