Publication number: 20170164114Abstract: The invention provides in some aspects a loudspeaker comprising an enclosure, a driver that is mounted in the enclosure, and an active diaphragm that is coupled to the driver to generate frontward-directed sound waves (“front waves”) directed outwardly from the enclosure and backward-directed sound waves (“back waves”) directed inwardly into the enclosure. A foam member, disposed within the enclosure and/or on an inner surface of a wall thereof, attenuates components of the back wave as a function of frequency, e.g., in the manner of a low-pass filter. The foam member comprises a foam of rigid material, namely, by way of example, a foam of metal, ceramic, carbon, silicon, glass, and/or epoxy. It (the foam member) may be disposed adjacent the reflective member and, indeed, together those members may comprise one or more walls of the enclosure, e.g., with the reflective member forming an outer surface of the wall(s) and with the foam member forming an inner surface.Type: ApplicationFiled: February 17, 2017Publication date: June 8, 2017Inventor: Godehard A.

Publication number: 20150260392Abstract: The foregoing are among the objects attained by the invention, which provides in some aspects a loudspeaker adapted for mounting in a lightbulb socket. The loudspeaker has a body that can, for example, be shaped like a lightbulb and that has a concavity that includes a first volumetric region. A wall that is disposed within the body and that at least partially defines that region includes one or more active diaphragms. The diaphragms generate (i) front waves directed from the first volumetric region to at least one of an environment and a second volumetric region, if any, defined within the concavity, and (ii) back waves directed into the volumetric region. A passive radiator that is elastically mounted in the wall passes from the volumetric region at least a portion of back waves generated by one or more of the active diaphragms.Type: ApplicationFiled: October 21, 2014Publication date: September 17, 2015Applicant: DR.

Patent number: 9060219Abstract: 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.Type: GrantFiled: August 14, 2013Date of Patent: June 16, 2015Assignee: DR.

Publication number: 20140334657Abstract: The invention provides, in some aspects, an audio headphone suitable for conversion to a loudspeaker. The device includes one or more earcups, each having a concavity that includes first and second volumetric regions and a wall that seals the regions from one another. The first volumetric region defines a space that receives a pinnea when the headphone is worn by a user, and the second volumetric region has one or more active drivers (a/k/a “speakers”). The wall includes one or more active diaphragms of those one or more active drivers. Those diaphragms generate front waves directed into the first volumetric region and back waves directed (back) into the second volumetric region. A passive radiator that is elastically mounted in the wall passes to the first volume from the second volume at least a portion of back waves generated by one or more of the active diaphragms. The invention provides, in other aspects, portable loudspeakers constructed in a manner of the earcups described above.Type: ApplicationFiled: May 13, 2014Publication date: November 13, 2014Applicant: DR.
