Acoustic enclosure for loudspeakers - has mechanical filters preventing transmission of vibrations between loudspeaker and casing

摘要

An acoustic enclosure has two or more loudspeakers which are separated by mechanical filters. The filters absorb vibrations which tend to be transmitted by the enclosure and which would affect the timbre of the sound frequencies. A loudspeaker enclosure (1) is made of wood and has a front panel (2) on which a bass frequency loudspeaker is mounted. A second loudspeaker (4) which reproduces the high frequencies is mounted on a flat ring (5) or rubber glued into an annular ring (6) of rigid plastics material. This is mounted in an opening (3) on the panel to provide mechanical filtering of frequencies between the loudspeaker and casing.
