Abstract
A loudspeaker system has an extended bass or low frequency response. The loudspeaker system integrates a passive radiator with a transducer. The loudspeaker system also mechanically isolates the passive radiator and the transducer. A support mechanism mechanically grounds vibrations or other forces from the transducer and passive radiator that may interfere or affect the operation of the loudspeaker.
Claims68
A loudspeaker, comprising:
- a passive radiator integrated with a transducer, where the passive radiator is mechanically isolated from the transducer.
A loudspeaker, comprising:
- a speaker enclosure having a back side and a frame;
- a support mechanism connected to the back side of the speaker enclosure;
- a transducer having an outside perimeter mounted to the support mechanism;
- and
- a passive radiator having an inside perimeter connected to the support mechanism, where the inside perimeter of the passive radiator encloses at least one point on the outside perimeter of the transducer and the passive radiator is connected to the frame.
An enclosure assembly for a loudspeaker, comprising:
- a speaker enclosure having a back side and a frame;
- a support mechanism connected to the back side of the speaker enclosure;
- and
- a passive radiator having an inside perimeter connected to the support mechanism, where the inside perimeter of the passive radiator encloses at least one point on the outside perimeter of the support mechanism, the passive radiator connected to the frame.
A speaker assembly for a loudspeaker, comprising:
- a support mechanism;
- a transducer having an outside perimeter mounted to the support mechanism;
- and
- a passive radiator having an inside perimeter connected to the support mechanism, where the inside perimeter of the passive radiator encloses at least one point on the outside perimeter of the transducer, the passive radiator connected to the frame.
The speaker assembly of claim 55, where the frequency range is in the range of about 40 Hz to about 2800 Hz.
A method for extending the bass response in a loudspeaker, comprising:
- integrating a passive radiator with a transducer;
- mechanically isolating the passive radiator from the transducer;
- and
- resonating the passive radiator in response to acoustical energy from the transducer.
