Patent ID: 6847725

Claim:
A self-contained assistive listening device for converting audio information transmitted on radio or infrared radiation carriers into audible sound at the ears of a user, the device comprising: A) at least one of i) radio receiver means for receiving, amplifying and decoding said radio radiation carrier and providing therefrom an electrical audio signal containing said audio information; and ii) infrared radiation receiver means for receiving, amplifying and decoding said infrared radiation carrier and providing therefrom an electrical audio signal containing said audio information; B) a microphone for receiving sound waves and providing therefrom an electrical audio signal; C) signal amplifier means connected to said microphone, and said at least one of said infrared radiation receiver means and said radio receiver means for amplifying said electrical signal received therefrom; D) volume control means connected to said amplifier means for adjusting the strength of said electrical signal from said amplifier means; E) electric power means for connecting and providing electric power to said device; F) a housing having broad front and back faces with the peripheries thereof joined together by a perimetral edge to define an enclosure, said enclosure containing said at least one of said radio receiver means and said infrared radiation receiver means, said signal amplifier means, said volume control means, and said electric power means, said housing removably supporting said microphone thereon; G) a pair of elongate arms, each of said arms connected at a proximal end to said housing; H) an earphone connected at the distal end of each of said arms and operatively connected to said signal amplifier means for converting said electrical signal into audible sound at the ears of the user; I) the microphone being disconnectable from the amplifier means.
