Abstract
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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
89 words
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.
Claim 2
Dependent Claim
89 words
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.
Claim 3
Dependent Claim
25 words
A structure as in claim 1 further including a voice-controlled electronic switch means for selectively controlling the system to operate in transmitting and receiving modes.
Claim 4
Dependent Claim
32 words
A structure as in claim 1 wherein said vibratable element comprises a piezoelectric element receiving signals from said communication system and in contact with said helmet rigid portion for vibrating the same.
Claim 5
Dependent Claim
34 words
A structure as in claim 1 wherein said vibratable element comprises an electromechanical element receiving signals from said voice communication system and in contact with said helmet rigid body portion for vibrating the same.
Claim 6
Dependent Claim
50 words
A structure as in claim 1 further including a resilient member secured to the outside of said protective helmet; said communication system including a transmitting and receiving circuit, and said recieving circuit supported by said resilient member and cushioned by said resilient member against damage from impact and the like.
Claim 7
Dependent Claim
39 words
A structure as in claim 1 wherein said voice communication system includes a first antenna for said transmitting circuit and a second antenna for said receiving circuit, each of said antennae supported by and cushioned by said resilient member.
