Protective helmet with voice communication system
First Claim
1. In a protective helmet of the type including a voice communication system for selectively operating in transmitting and receiving modes, the improvement comprising:
- said protective helmet including a rigid portion capable of vibration in the audio frequency range;
an audio signal transducer including a vibratable drive member, actuable in response to a received signal; and
,said drive member being positioned relative to said helmet to drivingly contact said rigid portion whereby said rigid portion functions as a diaphragm of the transducer to produce signals in the audio frequency range.

Abstract
An improved protective helmet of the type including a two-way voice controlled communication system having electronic transmitting and receiving circuitry. When incoming signals are received by the voice communication system, a transducer vibrates a rigid portion of the helmet, causing the helmet to act as a diaphragm to produce intelligible audible sounds. The electronic circuitry of the voice communication system is mounted in a resilient carrier for protection against damage from impact and shock to the helmet. Alternatively, the electronic circuitry may be supported on and protected by the conventional cushion lining of a protective helmet.
