PURPOSE:To demonstrate a bass characteristic sufficiently, by providing cement walls in the back and left and right sides and providing a reflection mechanism in the lower side in the speaker cabinet. CONSTITUTION:Bass from cabinet 18 toward the back or the side is prevented from passing through the cabinet as it is and escaping all by providing cement walls 2 and 6 of a high density and a high stiffness in the back and left and right sides of speaker cabinet 18, and this bass is reflected by walls 2 and 6, and a part of this reflected bass is caused to go forward. Then, bass from cabinet 18 toward the lower part is prevented from passing through the cabinet as it is and escaping all by providing reflection mechanisms 4, 14, 17 and 16, which reflect bass going toward the lower part forward, in the lower side of cabinet 18, and this bass is reflected through sound hole 4 and upper face hole 14 by high-density and high-stiffness cement reflection plate 17 and is caused to go forward through front open hole 16. |
