REDUCED ACOUSTIC COUPLING

摘要

An apparatus comprising: at least one speaker; and at least one microphone, wherein there is an acoustic coupling between the at least one speaker and the at least one microphone; at least one location defined by the at least one acoustic coupling between the apparatus at least one speaker and the apparatus at least one microphone; and at least one dampening element at the determined location, such that the at least one acoustic coupling between the at least one speaker and the at least one microphone is substantially reduced.
