A device for transforming mechanical acceleration into audible sound has been developed. The Acceleration-to-Sound Converter (ASC) produces a variable-frequency sound proportional to the acceleration size. It has various scale and shift capabilities. It comes in two basic configurations. The first consists of separate sensor unit and acceleration-to-sound circuit unit connected by a thin flexible cable. The second combines the two units into one. The sound may be produced by either speakers or earphones. The sensor unit's size is about 1x1x1 cm and it weighs about 10 gr. The processor unit's size is about 9x4x4 cm and it weighs about 100 gr. It is expected that these dimensions and weights will be reduced in future designs. The ASC is powered by a 9V source. The figure displays a prototype of the combined unit, containing internally two chargeble 9V batteries, with earphone.
