1. An amusement device comprisinga pressure transducer having an output, said pressure transducer generating an electrical resultant at said output of said pressure transducer in response to change of pressure on a surface of said pressure transducer;

  • a pliable covering having a hardness less than said pressure transducer, said pliable covering being mechanically coupled to said pressure transducer in such a manner as to allow for the movement of at least a portion of said pliable covering across said surface of said pressure transducer;

    an enclosure containing said pliable covering arranged so as to transfer movement along a surface of said enclosure to said pliable covering thereby causing movement of at least said portion of said pliable covering across said surface of said pressure transducer;

    a signal processing means including an amplifying valve, an input and an output, wherein said electronic resultant produced by said pressure transducer is connected to said input of said signal processing means and thereby multiplied in amplitude by a predetermined amount producing a processed resultant and presenting said processed resultant at said output of said signal processing means;

    a threshold detection means including an input connected to said output of said signal processing means, and an output, wherein an electronic trigger of predetermined form is presented at said output of said threshold detection means when said processed resultant presented at said output of said signal processing means attains a predetermined form;

    a retriggerable memory having an input and an output, said input of said memory connected to said output of said threshold detection means wherein an electronic resultant of said retriggerable memory is produced at said output of said retriggerable memory which is a function of past changes in said processed resultant presented at said output of said threshold detection means;

    a sound generating means including an input and an output, said input being connected to said output of said retriggerable memory, said sound generating means producing electronic signals representative of sounds at said output of said sound generating means when said electronic resultant of said retriggerable memory attains a predetermined form;

    an amplification means including an input and an output, said input being connected to said output of said sound generating means, said amplification means amplifying said electronic signals representative of sounds by a predetermined amount producing a waveform and presenting said waveform at said output of said amplification means;

    an output sound transducer having an input, said input of said output sound transducer being connected to said output of said amplification means, said output sound transducer producing audible sounds when said waveform produced at said output of said amplification means attains a predetermined form.
