Abstract: An apparatus for acoustic percussion of the human and animal body, the apparatus including an oscillator circuit for creating electrical signals for exciting a loudspeaker and producing sound waves; a waveform shaping circuit for shaping the electrical signals created by the oscillator into a waveform; an amplifier circuit for amplifying the signals shaped by the waveform shaper to the level required by the loudspeaker; a loudspeaker for producing sound waves when excited by the electrical signals created by the oscillator and shaped by the waveform shaper; a potentiometer to control the waveform rate created by the waveform shaper; a potentiometer to control the tone produced by the oscillator; and a potentiometer to control the volume of the sound produced by the loudspeaker. A preferred embodiment includes a battery for powering the apparatus, an activating mechanism, and a case or container for packaging the components of the apparatus.
