  • Patent number: 9693141
    Abstract: Embodiments are disclosed for a loudspeaker for producing directed acoustic vibrations. In some embodiments, a loudspeaker includes an electromagnetic transducer including diaphragm configured to generate acoustic vibrations. The loudspeaker may further include an aperture positioned in front of the diaphragm in a direction of propagation of the acoustic vibrations, the aperture including an opening having one or more protrusions forming an opening shape having non-uniform edges.

  • Patent number: 8477966
    Abstract: An in-wall speaker system having at least one pair of active transducers mounted in a wall section. The active transducers may be mounted in at least one enclosure. Each active transducer has a sound radiating surface. Each active transducer is also mounted substantially perpendicular to a surface of the wall section with the sound radiating surfaces substantially parallel to each other. The sound radiating surfaces may be facing each other or away from each other. The in-wall speaker system may also include one or more pairs of passive radiators to generate sound from sound pressure generated by the active transducers. The pairs of speakers in the wall section may be mounted vertically or horizontally within the wall, with a slot or a vent at the opening at the space between the speaker pairs.

  • Publication number: 20050036647
    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.
