Thumb drum-paddle
摘要:
There is disclosed a hand held percussion toy comprising a pair of substantially parallel surfaces, each surface having a perimeter edge, the pair of substantially parallel surfaces being joined together by a third surface connected between the perimeter edges of the pair of parallel surfaces to form a sealed enclosure having an interior volume, the third surface having a recess therein extending into the interior volume, the recess being shaped to receive a thumb or a finger of a person for holding the percussion toy while maintaining the seal of the sealed enclosure whereby a drum-like structure is formed which produces a resonant tone when struck by another object.
