  • Patent number: 9924249
    Abstract: A horn for use with a loudspeaker may include an entrance disposed at a first axial end of the horn and configured to receive a driver. A mouth may be disposed at a second axial end of the horn opposite the entrance. A contoured surface may extend between the entrance and the mouth. A cross sectional shape of a coverage pattern of audible sound emitted by the loudspeaker coupled with the horn may be independent of a shape of the entrance and a shape of the mouth.

  • Patent number: 9591397
    Abstract: A loudspeaker mounting assembly includes a frame, a sleeve, and a tilt-angle adjustment mechanism. The frame may include an outer frame, an inner frame rotatable about a frame axis relative to the outer frame, and a frame wall extending away from a rear side. The sleeve is coupled to the inner frame at a pivot axis and is tiltable to a plurality of tilt angles relative to the inner frame. The tilt-angle adjustment mechanism is engageable with the sleeve to enable selection of a desired tilt angle. A loudspeaker may be mounted to the sleeve such that the loudspeaker may be swiveled about the frame axis and tilted about the pivot axis.

  • Patent number: 7450729
    Abstract: One embodiment of a low-profile transducer includes a at least one fin perpendicularly mounted on a planar diaphragm, with a voice coil mounted onto the fin. The voice coil may reside in a strong uniform magnetic field. The locations at which the diaphragm is connected to a frame may be coplanar with a center of mass of the diaphragm. The three-dimensional structure of diaphragm and fins may be formed using origami techniques.
