Patent ID: 7325357

Claim:
A noisemaking device that produces high frequency vibrations and sound waves in response to movement of the device comprising: an essentially watertight housing defining an interior compartment with an inside surface, a flexible, essentially straight tone wire with a first and a second end, said first end attached at said inside surface of the housing, said second end extending horizontally into said interior compartment defined by the housing, a contact surface with a first end and a second end larger than the first end within said interior compartment defined by the housing, said wire attached near said first end of said contact surface and a weighted member fixedly attached to said flexible tone wire, such that in response to movement of said device, said weighted member strikes said contact surface near the second end causing said flexible tone wire to produce high frequency vibrations, said contact surface being devoid of cushioning material that would absorb energy or dampen vibrations produced on said wire when said weighted portion strikes said contact surface, said weighted member and said flexible tone wire sized to provide tension on said wire without significant flexure of said wire when in a static condition, and to limit movement of said weighted member within the housing to an arclike path that prevents bending of said flexible tone wire when the device is moved, and subsequent striking of said contact surface by said weighted member producing more complex high frequency vibrations on said wire.
