The exterior shell of the loudspeaker box of the bamboo rhythm loudspeaker box and the vertical column above the loudspeaker box are both made of bamboo materials. The vertical column above could float up and down along with the rhythm of the sound from the loudspeaker box and shows different colors. When the loudspeaker box is turned off, the above vertical column will automatically retreat to the interior part of the loudspeaker box. When bamboo encounters music and science and technology, it could provide people with brand new experience.
