Sound effect adjusting apparatus, method, and program

Provided is an acoustic transducer which is used by being fitted into an ear of a listener, is formed in a compact and lightweight shape, and preferably prevents re-reflection of a sound wave. An acoustic transduceris formed of a film-shaped material having an expanding and contracting action and includes a cylindrical acoustic transducing element. The cylindrical acoustic transducing elementalso functions as a sound guide tube.
