PURPOSE:To convert the motion of a human body who is practicing a rhythm exercise, etc., into a musical sound by fitting an angle detecting means which outputs a signal corresponding to the bending angle of a joint to a mount tool mounted on the joint part of the human body and controlling the musical sound according to the bending angle of the joint. CONSTITUTION:For example, a right-elbow supporter 2R is put on the right arm, which is bent as shown by a two alternate long and short dashes line A or stretched as shown by a two alternate long and short dashes line B, so that a plate body 32 rotates around a pin 33 as its axis according to the motion of the arm. The projection part 40b of a sliding contact 40 slides on a resistance body 38 according to the rotation and the resistance values between the resistance body 38, and a terminal 38a and the terminal 39a of a fixed contact 39 vary according to the position of the sliding contact 40, i.e., the bending angle of the right arm. Consequently, the bending angles of the joints of respective parts of the human body are securely detected and the musical sound can be controlled according to the detected angles, so the motion of the human body who is practicing the rhythm exercise, etc., can be converted into the musical sound. |
