Voice transmission system with remote microphone

Claim 1

A voice transmission system for use with a face mask having a passage, the passage including an inner end proximate a person's mouth wearing the face mask and an outer end having a membrane mounted thereon, said voice transmission system comprising: a microphone assembly including: (i) a microphone for receiving the person's voice through or around the membrane, and (ii) a mounting unit for removably coupling said microphone assembly to the passage of the face mask such that said microphone is located proximate the membrane, said mounting unit including: (i) a base plate within which said microphone is mounted, (ii) a collar extending outwardly from said base plate, and (iii) a plurality of resiliently deflectable spring clips attached to said base plate and extending along the outer surface of said collar, said spring clips being designed to: (i) resiliently deflect during coupling of said microphone assembly to the passage, (ii) engage an outer surface of the passage with a predetermined amount of resistance when said microphone assembly is coupled to the passage, and (iii) resiliently deflect during uncoupling of said microphone assembly from the passage; an amplifier body remote from said microphone assembly and substantially enclosing an amplifier assembly, a speaker, and a power source; and a conductor for electrically interconnecting said microphone with said amplifier assembly, said speaker, and said power source; whereby said microphone receives the person's voice through or around the membrane at the outer end of the passage, said amplifier assembly amplifies the voice signal received from said microphone, and said speaker externally transmits the amplified voice signal.
