TRAINING APPARATUS FOR SENSE OF PITCH AND TRAINING METHOD FOR SENSE OF PITCH USING THE SAME

摘要

A pitch training apparatus (100) comprises an interface unit including circular shaped attachable controlling balls, holders on which the controlling balls are placed, sensors which detect distance between the controlling balls and floor by being arranged on the floor where the controlling balls are in contact in the holder; a speaker (130) to which constant sound is output; a control circuit (140) which controls the pitch output from the speaker (130) to increase to be proportional to the distance; a power supplying unit (150) which supplies power to the speaker (130) and the control circuit (140); and a case (160) which houses the interface unit, speaker (130), control circuit (140), and power supplying unit (150).
