초록 ▼

An earpiece has a structural configuration effective to removably interlock its outer surface contiguously to the outer ear auricle of the earpiece wearer. A microphone substantially exclusively receives, from the air of the external auditory canal, outbound voice sounds caused by the reverse modulation of the tympanic membrane when the earpiece wearer speaks. An outbound audio circuit is electrically connected to the microphone which converts the outbound voice sounds to electrical voice signals. The outbound audio circuit amplifies the outbound electrical voice signals to a preselected fixed level output gain and removes noise from the voice signals. Specific features of the invention are directed to a two-way communication system, the structure of a speaker/microphone module, the structural configuration of an earpiece assembly, specific control circuitry, and a particular assembly for conducting a method of communicating voice sounds substantially exclusively from the air of the external auditory canal while substantially eliminating audio vibration pickup of sound signals by bone conduction. The voice transmission system and method effect intelligible voice communication in an environment having ambient noise at a level greater than 90 decibels.

대표청구항 ▼

A control circuit for a voice transmission system including an earpiece member having a structural configuration with an outer surface effective to removably interlock contiguously to the outer ear auricle of a wearer of the earpiece member, said earpiece member including a canal extension with means for receiving outbound voice sounds within the ear canal and means for sending inbound sounds to the ear canal, said circuit comprising: a) outbound audio circuit means, inbound audio circuit means and switch means for alternately activating the outbound audio circuit means and inbound audio circuit means, b) the outbound audio circuit means being effective to receive outbound electrical voice signals from first microphone means which picks up outgoing voice sounds from said means for receiving outbound voice sounds produced by reverse modulation of the tympanic membrane and obtained from the air within the external auditory canal of a person, c) the inbound audio circuit means being effective to send inbound electrical sound signals from second microphone means to first speaker means which sends sounds into the external auditory canal to said tympanic membrane through said means for sending inbound sounds, d) the outbound audio circuit means including amplifier means and processor means, e) said amplifier means being effective to amplify intelligible said electrical voice signals said to a preselected fixed level output gain for producing increased gain audio signals each having a voice portion and a noise portion, f) said processor means being effective to separate the noise portion from the voice portion for producing a clear voice sound to be transmitted by second speaker means disposed at a location remote from said person.
