Abstract

PURPOSE: To provide an acoustic reproducing device which is fitted with a speaker in the headrest of the seat of a vehicle, resolves the problem that the reproduced sound pressure frequency characteristic can not be satisfied as the headrest becomes larger, and can obtain the flat and wide-band reproduced sound pressure frequency characteristic for the lateral width of the headrest with no speaker without nearly widening the width.
CONSTITUTION: An acoustic pipe 3 is connected to the front section of the vibrating plate of a speaker unit 1, a horn wall is formed with a sound absorbing material 4 in the acoustic pipe 3, a speaker device having a rectangular structure with a very narrow lateral width on the opening section of the horn wall is buried in a headrest 6, the speaker device can be fitted without nearly widening the lateral width of the headrest 6, and the flat and wide-band reproduced sound pressure frequency characteristic can be provided.
