ABSTRACT:
An electrically chargeable plate of predetermined surface area is retained in contact with the skin of each of two participants. An electrical conductor connects each plate to one of the two terminals of the audio output of one of the channels of a stereo amplifier while the other channel plays through its speaker. Physical contact between the participants completes the circuit enabling both participants to feel the modulated impulses of the sound as well as hear the output of the speaker on the other channel. Both plates may be worn by one person to experience a comparable feeling or one plate and an electrically chargeable wand used in place of or in addition to the other plate enables either one or two persons to participate.
