Abstract: The present invention provides a vibroacoustic sound therapeutic system including an acoustic energy source having means for generating an acoustic drive signal, the acoustic drive signal being characterized by a frequency sweep between a relatively low frequency and a relatively high frequency, and one or more acoustic transducers adapted for operation in a liquid medium, the transducers being responsive to the acoustic drive signal to generate acoustic energy at frequencies corresponding to frequencies of the acoustic drive signal.

Abstract: A talking trading card playing system consists of a portable card player and a plurality of trading cards. Each card includes a card body having front and back surfaces, flexible sheets affixed to the front surface and to the back surface of the housing, and a voice chip for storing and generating sound patterns. The portable player comprises a power source located in the housing for supplying electrical power to the voice chip, and sound generation components. The subject trading card and player may be activated by aligning the card with electrical contacts on the face of the player, thereby establishing electrical contact between the card and the player.

Abstract: A trading card capable of generating sounds comprises a thin housing having front and back surfaces, flexible sheets affixed to the front surface and to the back surface of the housing, a voice chip located in the housing for generating patterns of sounds, a battery located in the housing for supplying electrical power to the voice chip, and a switch located in the housing for activating the voice chip. The subject trading card may be activated by squeezing the flexible sheets between the thumb and forefinger at a selected switch location.
