Patent ID: 8493194

Claim:
A bicycle electronic signaling device comprising: (a) a bicycle; (b) a sound generation means (i) drawing not substantially more than 2 ampere-hours at 12 volts; (ii) producing substantially the sound of a car horn with pitch within the range of approximately 340 to 500 hertz and loudness within the range of approximately 107 to 112 decibels; (c) a plurality of batteries, each battery not substantially bigger than size AAA, and each battery having an effective amperage being substantially less than the rated current output of 1.2 ampere-hours when connected to said sound generation means; (d) at least one switch for controlling the flow of current from said plurality of batteries to said sound generation means; and (e) one or more clamps or fasteners attaching said switch and other components of said device to said bicycle; wherein said sound generation means is attached to said bicycle or other components of said device by a bracket whose resonance frequency is tuned to substantially match the vibrating frequency of said sound generation means.
