Abstract

PURPOSE: To increase the level of a collected sound by arranging an acoustic tube for sound irradiation at one focus on an elliptic surface of rotation and arranging a speaker as a sound source outside a reflecting body.
CONSTITUTION: The speaker 2 is fitted as the sound source to a support 1 which is fixed to a structure and the reflection body 5 which includes part of the elliptic surface 4 of rotation, which has one axis 3, e.g. perpendicular line as an axis of rotation and has two focuses S1 and S2 on the axis 3, as its internal surface is fitted to the support 1. The acoustic tube 6 is fitted extending from the speaker 2 to one focus S1 of the reflection body 5 and a nozzle 7 is fitted there while facing the center of the reflection body 5. The sound from the speaker 2 reaches the nozzle 7 through the acoustic tube 6 to irradiate the reflection body 5 and the sound is reflected by the reflection body 5 and converged on the focus S2 without leaking out. Consequently, a large output is obtained without disordering the sound field in the reflection body 5.
