ELECTROACOUSTICAL TRANSDUCING

摘要

Electroacoustical apparatus includes at least first and second acoustically coupled electroacoustical drivers. An electrical network couples their inputs so that an electrical drive signal applied to one reduces the effect of acoustic coupling from that one to the other.

1. An electroacoustical apparatus comprising:
a cabinet enclosure, at least first and second electroacoustical drivers acoustically coupled in said cabinet enclosure each having an input for receiving respective electrical signals, wherein an audio signal for the second electroacoustical driver is provided on a second driver input, the audio signal for the second electroacoustical driver comprising (a) a non zero drive signal component; and (b) a non zero opposition signal component, distinct from the drive signal component, that substantially cancels sympathetic vibration of the second electroacoustical driver caused by acoustic coupling from the first electroacoustical driver in the cabinet enclosure when a first electrical drive signal is applied to a first driver input.
