LOUDSPEAKER SYSTEM WITH ACOUSTIC EQUALISATION

摘要

A loudspeaker system is disclosed including a vented enclosure and at least one electroacoustic transducer mounted in the enclosure. The loudspeaker system includes at least one resonance controlling structure associated with the vented enclosure for controlling and/or cancelling a resonance peak in the enclosure to provide a flatter frequency response for the system and/or to reduce distortion in said system. The resonance controlling structure includes an open end and a closed end and is arranged such that sound waves entering the open end are reflected and arrive out of phase at the open end. The resonance controlling structure may include at least one resonance controlling duct or waveguide placed with its open end near an end of a venting duct associated with the vented enclosure.
