ABSTRACT:
A stereophonic pillow speaker system is disclosed wherein first and second baffle frames and loudspeakers thereon derive near field effects at points proximal to the speakers in response to electrical signals from an amplifier. Also included are pillow means for providing comfort to a listener's head between the loudspeakers and to isolate mechanical vibrations between the baffle frames and a listener's head when the ears of the listener are in registry with the near field effect. The system includes equalizer circuit means for tailoring of the electrical signals from the amplifier to achieve a high quality sound, to compensate for deficiencies of the loudspeakers at extreme low and high frequencies, and to substantially eliminate out-of-phase rumble.
