Abstract:
The present technique relates to an acoustic tube and an acoustic reproduction apparatus that can generate an evanescent wave at a lower cost. An acoustic tube includes an acoustic path longer than an external dimension of the acoustic tube and includes a plurality of opening portions or a slit-like opening portion. When a sound wave advances in the acoustic tube, sound waves are output from the plurality of opening portions or from a plurality of positions of the slit-like opening portion, and the sound waves are combined to form an evanescent wave. The present technique can be applied to an acoustic tube, an acoustic reproduction apparatus including the acoustic tube, and the like.

Claim (Index 6):
The acoustic tube according to  claim 1 , wherein\n the acoustic tube is obtained by winding a cylindrical tube to form a spiral shape.
