Title: SPEAKER SYSTEM FOR MOVING BODY
Abstract:
Provided is a speaker system that is for a moving body and that makes it possible to improve acoustic characteristics in the bass range. A speaker unit (2) and an enclosure (3) are provided to a central section of a door panel (10) in the vertical direction or to a part of the door panel (10) above the central section. An end (4B) of a tube member (4) opens toward a vehicle interior space (A1) below the door panel (10). Configuring in this manner yields a so-called bass reflex speaker system. In addition, a bass range component is amplified and emitted by the tube member (4). Furthermore, the door panel (10) has high acoustic characteristics with respect to the bass range component, and sound comprising mainly the bass range component can be emitted therebelow. As a result, bass can be made to reverberate efficiently within a space in a moving body.
