Title
(EN) Audio playback system
(ZH) 音响再现系统
Abstract
(EN)
Provided is an audio playback system, which reduces a restriction on a place of installation and which reduces the dispersion of sound pressure frequency characteristics of a low range among the seats in a compartment so that a comfortable low sound can be enjoyed at any seat. The audio playback system comprises a first filter (108), to which a sound signal outputted from a playback device (107) for playing back the sound signal is inputted, for passing a band lower than a primary resonance frequency in the compartment, a first sub-woofer (104), to which the output signal of the first filter (108) is inputted, a second filter (109), to which the aural signal outputted from the playback device (107) is inputted, for passing a band containing the primary resonance frequency of the compartment, and a second sub-woofer (105), to which the output signal of the second filter (109) is inputted, and which is disposed near the node of the primary resonance mode of the compartment.
