Abstract

PURPOSE:To realize stereophonic listening excellent in low-frequenct range without causing fatigue by connecting right and left stereophonic sources to the right and left inputs of an open type headphone and by reproducing sources by woofers via LPFs. CONSTITUTION:Left and right stereophonic sources 21 and 22 are connected to left and right electro-acoustic converters 24 and 25 of an open type headphone put on human head 23, and LPFs 26 and 27 are connected to sources 21 and 22 to extract signals in the low frequency range, which are mixed and amplified by amplifier 28 before being reproduced by woofers 29. Consequently, an influence of a room constant, occurring in reproduction by only speakers, reproduction insufficient in low frequency range like headphone reproduction, and a fault that a sound image appearing in the center of the head are all eliminated.
