A muffler sound simulator for bicycles and other non-motorized vehicles or toys. The simulator is driven through the circular motion of the wheel. The bicycle wheel is engaged by a drive wheel that in turn manipulates a drive shaft that acts upon an actuator. The actuator rotates, striking the hammer. The duel action of the load spring and the repositioning spring allow the hammer to interface repeatedly against the tympanic membrane. The sound derived from the resonation of the membrane is directed through the hollow casing, amplifying the sound that is generated. Another embodiment of the device is a muffler sound simulator for bicycles and other non-motorized vehicles or toys that is a mechanically driven actuator that compresses a switch tab against a momentary contact switch that is electrically connected to a printed circuit, and a speaker for the reaction output of the printed circuit.
