Abstract
The invention provides, in one aspect, a loudspeaker that has electrodynamically-driven piston mounted in one external wall and that has movable panels in one or more other external walls. Those panels are air-coupled to the piston, e.g., via air within the enclosure, such that vibrational motion of the piston causes the vibration of the panels, thereby, improving the overall air coupling of the piston to the external environment, e.g., the listening room. Further aspects of the invention provide an improved driver for use, e.g., in the aforementioned loudspeaker. The driver comprises a three-part piston having first and second diaphragms coupled back-to-back with one another and having a voice coil face-mounted (or front-mounted) within the second diaphragm.
Claims15
A loudspeaker comprising
- an enclosure,
- a driver mounted in an external wall of the enclosure, the driver including a piston having
- i) first and second diaphragms coupled back-to-back with one another, the second diaphragm being cone-shaped and facing into the interior of the enclosure, and
- ii) a voice coil at least partially within a face of the cone-shaped second diaphragm;
- a passive radiator comprising panel elastically mounted in another external wall of the enclosure and that is air-coupled to the piston.
A loudspeaker comprising
- an enclosure,
- a driver mounted in an external wall of the enclosure, the driver including a piston having
- i) first and second diaphragms coupled back-to-back with one another, the second diaphragm being cone-shaped and facing into the interior of the enclosure, and
- ii) a voice coil at least partially within a face of the cone-shaped second diaphragm;
- and
- two or more passive radiators, each passive radiator comprising a panel that is elastically mounted in a respective one of each of two or more other external walls of the enclosure and that is air-coupled to the piston.
A driver for use in a loudspeaker, the driver comprising
- a piston having first and second diaphragms coupled back-to-back with one another, the second diaphragm being cone-shaped and facing into the interior of the enclosure, and
- a voice coil at least partially within a face of the cone-shaped second diaphragm.
