Abstract

A technique is described whereby audio receiving self-adjusting speakers (SAS) automatically adjust to frequency and/or volume characteristics according to the nature of the audio or an imbedded code. The concept is an improvement over systems which incorporate self-adjustment in the amplifier components, since the SAS circuitry is designed for only that speaker, whereas amplifier self-adjustment circuitry must satisfy a wide variety of speaker components. The concept is also applicable to overcoming limitations of analog media, telephony speakers, remote controlled speakers and particularly conducive to digital broadcast technology.
