Abstract
Apparatus for producing signals of varying volume and pitch which are functions of the magnitude and distribution respectively, of weight (or weights) placed upon a platform hinged at one corner and swingable in mutually orthogonal directions. Sensors convert the physical displacements occurring at first and second corners opposite of the platform adjacent to the hinged corner into signals for controlling the volume and pitch of an output signal. Alternatively, displacement of the platform may be controlled by the application of varying pressure by means other than full body weight, such as the operator's finger(s). The apparatus may be utilized as a unique means for producing music or musical sounds responsive to a person dancing or otherwise moving upon the platform to provide an entertainment form which is both unusual and enjoyable. The varying degree of sophistication of equipment design enables its use to encompass as diverse a range of devices as that of a rugged toy having a simplicity of design and a sensitive musical instrument capable of producing precise quality tones providing a broad range of applications within the field of entertainment.
