  • Patent number: 5282251
    Abstract: A portable speaker system for the hearing impaired, comprising at least two speakers mounted on a framework which can be moved easily around a room, and specifically moved to allow one speaker to be directed at the left ear, and the other speaker directed to the right ear. As the speakers are adjustable in their direction, and volume, a person with impaired hearing can position the speakers at the side of their chair, adjust the volume as required, and hear the audio sound at their level of volume, while persons with normal hearing are allowed to hear the same audio sound at normal levels. In another embodiment of this invention, each speaker can be connected to a separate sound source, to produce a stereo effect.
