Abstract
In a key board system for an electronic musical instrument, input signals for the instrument generated in response to key actuation have an electrical characteristic which varies as a function of the key actuation force. The foregoing results from the deflection of a mass-carrying leaf spring in response to a key stroke, the input signal being generated by a piezoelectric element mounted on the leaf spring and being deformed in response to the deflection thereof.
