Claims

[Claims for Utility Model Registration] 1. Consisting of an acoustic tube formed continuously from the back of the speaker unit, an empty space provided in the front of the speaker unit, and a bass reflex port provided in this empty space, In a speaker system for bass reproduction in which an opening of a tube is connected to a vacant chamber, a partition plate is provided to form the vacant chamber and an acoustic tube,
1. A speaker system for bass reproduction, characterized in that one surface of the acoustic tube from one end of the acoustic tube to the other end is formed by the partition plate. 2 Consists of an acoustic tube formed continuously from the back of the speaker unit, an empty chamber provided in the front of the speaker unit, and a bass reflex port provided in this empty chamber, and the opening of the acoustic tube is turned into an empty chamber. What is claimed is: 1. A speaker system for bass reproduction that is connected to each other, wherein the acoustic tube is provided outside an enclosure of the speaker system for bass reproduction, and is configured to have flexibility. 3. The speaker system for bass reproduction according to claim 1 or 2, wherein the sound emission direction of the speaker unit and the direction of the port of the bass reflex are configured to form approximately 90 degrees. 4. The speaker system for bass reproduction according to claim 1, 2 or 3, wherein the resonance frequency of the port of the bass reflex and the frequency at which a half wavelength is placed on the acoustic tube are substantially the same.
