Abstract
Two way communication between a motor cycle driver and a passenger is achieved by having a microphone and earpiece capsules for each helmet and interconnected by a wire. A source of energy may be derived from a battery or from the vehicle generator. A microphone capsule (2) and one or two earpiece capsules (3) are mounted in the helmets (1) of a motor cycle driver and passenger. The capsules are interconnected by a wire (4) with connectors which are readily disconnected in case of shocks or accidents. Electrical energy is supplied from a battery (5) accumulater (6) or from the vehicle generator in which case a capacitor is connected to the circuit to eliminate parasitic interference.
