Abstract
A passive radiator includes an elastomeric member and mass. The elastomeric member defines a suspension structure that has an inner peripheral boarder and an outer peripheral boarder and a first snap-attach feature that is arranged along the outer peripheral boarder of the suspension structure. The first snap-attach feature enables the elastomeric member to be coupled to a mating feature. The mass is supported along the inner peripheral boarder of the suspension structure and is configured for pistonic movement, relative to the first snap-attach feature, along a motion axis of the passive radiator.
Claims16
A loudspeaker comprising:
- an acoustic enclosure defining an acoustic cavity;
- a passive radiator coupled to the acoustic enclosure;
- and
- an electro-acoustic transducer mounted to the acoustic enclosure such that sound waves generated by the electro-acoustic transducer are capable of acoustically energizing the passive radiator,
- wherein the passive radiator comprises:
- an elastomeric member which defines:
- a suspension structure having an inner peripheral boarder and an outer peripheral boarder;
- and
- a first snap-attach feature arranged along the outer peripheral boarder of the suspension structure for coupling the elastomeric member to a mating element on the acoustic enclosure;
- and
- a mass supported along the inner peripheral boarder of the suspension structure and configured for pistonic movement, relative to the first snap-attach feature, along a motion axis.
