Abstract

PURPOSE:To effectively remove a noise to individual listeners by disposing an auxiliary speaker for removing the noise near to the listener on a noise removing device used for an audio device disposed on a car or the like. CONSTITUTION:In the audio device 1, the signal of a cassette player 1a is amplified by an amplifier 1b and reproduced by the speaker 1c. The noise in an engine room is collected by a microphone 2 disposed in the engine room to generate the cancel sound of the engine noise from the auxiliary speaker 5 through a filter 3, an amplifier 4. Since a distance between the ear of the listener and the auxiliary speaker 5 is shortened by disposing the auxiliary speaker 5 at both the sides of the head rest 6 of respective chairs, the noise is effectively removed at any position.
