Abstract

PURPOSE: To increase an acoustic effect and obtain a playback capacity of a low register by providing a wall face having a spherical shape, a sound tube provided with an opening on the wall face and continuously connected to the shape of the wall face, and a driver unit at the entrance.
CONSTITUTION: A sound tube 2 continuously connected to the wall face of a sound tube opening 5 and a driver unit 3 at the entrance of the sound tube 2 are provided in the sound tube opening 5 of an acoustic playback room 1 having a spherical wall face. The sound tube 2 couninuously and smoothly comes into contact with wall face of the acoustic playback room 1, and the wave faces of sound made from the driver unit 3 gradually disperses to the acoustic playback room 1 to efficiently propagate the acoustic output. Further, the area of the sound tube opening 5 is made larger to do stiffness control in the same way with the time when listening with a headphone, and the transmission characteristic of the acoustic output of the driver unit 3 is widened to the direct current zone to obtain a low register playback capacity. In this way, an even transmission can be realized regarding frequency and a listening position at a high acoustic conversion efficiency in a low zone.
