Abstract

A battery and generator operated electro-mechanical device looks like an engine and emits engine sounds. The engine attaches to a bicycle frame giving the bicycle the appearance of being a motor bike. The engine makes an authentic idle sound when first started up and sounds like an engine accelerating to full throttle as the bike is pedalled. In a second embodiment, a fully mechanical engine sound is produced whenever the bike is in motion. Both embodiments are housed in an authentic looking engine housing.

Claims

1. A toy sound generator to simulate engine sounds for mounting on a bicycle comprising,

a) a hollow engine shell with mounting means, said mounting means attachable to frame elements of a bicycle,

b) batteries in circuit with an audio oscillator and a sound transducer, said batteries, oscillator and transducer located in said shell,

c) circuit modulation means comprising a bike generator driving a light means which drives a photocell, output from said photocell directed to said audio oscillator,

d) attachment means to connect said generator to said light means,

e) said audio oscillator comprising a resistor-capacitor network providing sound signals to said sound transducer, said oscillator modulated by said bike generator as that bicycle said sound generator is mounted upon is caused to move by a user.

2. The toy sound generator of claim 1 where sound transducer is a loudspeaker in registration with openings in said shell.

3. The toy sound generator of claim 1 wherein said audio oscillator comprises an integrated circuit member with a plurality of engine sound signals stored therein.

4. The toy sound generator of claim 1 wherein said bike generator is a low voltage generator driven by contact with a moving portion of a bicycle wheel.
