Abstract

PURPOSE:To satisfactorily execute a disassembling and assembling and an attaching by coupling a cap-shaped cylinder body through a combining part to a main cylinder body to have the combining part on an upper edge, forming it in a pole-shape as a whole, providing a sound releasing hole in the side surface of the cylinder body and successively arranging the plural couples of the sound releasing devices in upper and lower directions. CONSTITUTION:A main cylinder body 17 is composed of a first frame 10 formed by having a sound releasing hole 11 of a meshshape, where an acoustic impedance is small, in the side surface of the pole shape and having an faucet joint part 12 on the upper edge, a combining cylinder body 13 of short length combined to the lower edge, a second frame 15 joined to the lower edge of the combining cylinder body 13 and formed in the same way as the above-mentioned first frame 10 and a body 16 as a supporting pole to be joined to the lower edge of the second frame 15. In the inside of the cylinder body, the plural couples of sound releasing devices 23, which are composed of a speaker unit 21 and a diffuser 22 arranged with facing each other over an interval in the high order and the low order of the sound releasing hole 11, are successively arranged in the upper and lower directions. Thus, the satisfactory disassembling and assembling and attaching can be executed and the titled device goes to be easily carried.
