Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
117 words
An ear transceiver assembly comprising: (a) a headphone housing adapted to be fitted over the ear of the user, (b) a speaker assembly contained in the housing and electrically connected to the receiver circuitry of a transceiver unit, (c) a funnel-shaped open interior bone conduction microphone assembly contained in and connected to the headphone housing adjacent the speaker assembly and electrically connected to the transmitter circuitry in the transceiver unit, said microphone assembly projects into and firmly engages a portion of the auditory canal of the user and comprises both an electromechanical sensing element and a support element therefore, wherein said speaker assembly is mounted to supply its acoustic output through and unimpeded by said microphone assembly.
Claim 2
Dependent Claim
117 words

Claim 3
Dependent Claim
20 words
The ear transceiver assembly as set forth in claim 1, wherein: (a) the electromechanical sensing element is a piezoelectric crystal.
Claim 4
Dependent Claim
52 words
The ear transceiver transducer assembly as set forth in claim 2, wherein: (a) the support element is a pliable funnel-shaped piece configured to fit into the auditory canal of the user, and (b) the piezoelectric crystal is an elongated element supported in direct contact with the support element along its entire length.
Claim 5
Dependent Claim
