Vibrations in the Loudspeaker Enclosure Evaluated by Hot Wire Anemometry and Laser Interferometry

Vibration states of the loudspeaker enclosure were examined by the laser interferometry and hot wire anemometry. According to simple expressions, air pressure in the enclosure is independent on air density. This statement has been tested by the use of gases indicated by very different densities (air, He, SF6), and interferometric data show a strong dependence of vibration states of the enclosure walls on density, when driving frequency increases from 500 Hz up to 1 kHz. The principal reason for a deviation resides in the imaginary part of the Morse impedance exerted by the vibrating gas within the enclosure.
