Percussion instrument using touch switch. Electric current flows by
touching conducting pad with conducting stick. The microcontroller in
main portion detects the said electronic current and recognizes which pad
is hit by which stick to generate the sound of drum of hit pad. The stick
portion may further contain vibration sensor and in this case the
microcontroller recognizes the hit impact strength of stick on pad by
analyzing the output of vibration sensor to control the volume of sound
of drum. The information about playing drum recognized by microcontroller
can be transmitted to outer system like PC by communication portion in
main portion or used to generate the sound of drum by sound generation
portion in main portion and if the communication portion is contained in
main portion then the sound generation portion may be omitted.
