ACOUSTIC ISOLATION OF VIBRATION TRANSDUCER

摘要

An assembly comprising a vibration-producing transducer such as a loudspeaker mounted adjacent to a vibration-transmitting body such as the speaker housing, and a vibration-absorbing gel gasket in contact with (preferably between) the transducer and said body. Gels, especially the preferred triblock copolymer gels having natural resonance frequencies below the audible range, are arranged to reduce radiation from the housing of a speaker of sounds which are intended to be private, for example in headphones or mobile telephones; or to reduce unwanted resonance and interference between loudspeakers and their housing or adjacent loudspeakers, which might otherwise impair the fidelity of loudspeaker performance.
