PURPOSE:To sensibly change the timbre, volume and level of a sound by providing a pressure sensitive conductive element for detecting a pressing force against a key cover, between a key body and the key cover. CONSTITUTION:When a key is pushed by a finger at the upper surface of a key cover 6, the pressing force by the finger acting upon the key cover 6 elastically deforms a top wall made of an elastic material so that a pressure sensitive conductive element 11 positioned therebelow is pressed. Meanwhile, a key body is pushed by means of the pressed pressure sensitive conductive element 11. Thereby it is possible to sensibly change the timbre, volume and pitches of a sound generated by the pushed key. |
