Abstract: A haptic transducer is provided, comprising a motor including a yoke, an inner cavity formed by the yoke, and a magnet assembly disposed within the inner cavity; a diaphragm disposed above the magnet assembly; a suspension extending concentrically around the diaphragm and having an inner edge attached to the diaphragm and an outer edge attached to the yoke; a cylindrical coil coupled to the diaphragm and suspended within the inner cavity around the magnet assembly; a first hole extending through the motor; and a second hole axially aligned with the first hole and extending through the diaphragm, a fastener extending through the first hole into the second hole. A footplate system is also provided, comprising a footplate configured for placement in a piece of footwear; a moving motor transducer configured to transfer haptic sensations to the footplate; and a top fastener configured to secure the haptic transducer to the footplate.

Abstract: Embodiments include a haptic transducer device comprising a magnetic assembly including a yoke and a magnet disposed within an inner cavity formed by the yoke. The device further includes a diaphragm having a top surface, a ledge projecting below and outwards relative to the top surface, and a sidewall extending downwards from the ledge towards the inner cavity. The device also includes a suspension extending concentrically around the diaphragm and including arms extending between inner and outer edges of the suspension, the inner edge being attached to the ledge of the diaphragm and the outer edge being attached to the outer ledge of the yoke. The device further includes a coil attached to the sidewall of the diaphragm and suspended within the inner cavity. One embodiment further includes an attachment groove integrated into the top surface of the diaphragm and configured for receiving attachment structures included on a footwear insole.

Abstract: Systems and apparatuses are provided for vibration confinement and stress management in a loudspeaker. In one embodiment, the loudspeaker comprises a diaphragm that extends from an inner diaphragm region (e.g., dome or cone-shaped) to an outer diaphragm region, wherein the outer diaphragm region bends at a defined angle (e.g., between about 45 degrees and about 135 degrees) relative to the inner diaphragm region. The loudspeaker also comprises a suspension member extending from an inner suspension region to an outer suspension region, the inner suspension region overlapping and attaching with the outer diaphragm region. The bend in the diaphragm isolates the inner diaphragm region from spurious vibrations in the suspension member.

Abstract: This invention provides a speaker port with a flare having an inner wall that minimizes or reduces boundary layer separation. Fluids, such as air and sound waves, flow through the port at a higher velocity when boundary layer separation is minimized or reduced. The inner wall of the port is contoured so that the pressure gradient or change in pressure along the longitudinal axis of the port from its inlet duct to outlet duct is substantially constant.

Abstract: A speaker system is provided, including a suspension element having an outer edge and an inner edge. The suspension element, such as a spider or surround, varies in shape along at least a portion of the suspension element to help relieve both the radial and tangential stress placed on the suspension element when it is stretched. The shape employed in the suspension element allows the suspension element to stretch more easily, creating a higher performance speaker of the same size by increasing the diaphragm excursion and voice coil movement.

Abstract: This invention provides a transducer having at least two surrounds supporting a cylinder. With at least two surrounds, the transducer may handle more power. This increased power may be used to drive the voice coil that is wrapped around the cylinder enabling a greater excursion range of the diaphragm. With a greater excursion range, the transducer may operate at low frequency as well as mid to high frequencies. The two surrounds may also be coupled to the cylinder increasing stability of the cylinder. With the two suspensions stabilizing the cylinder, the side-to-side movement of the cylinder may be reduced minimizing the chance of the voice coil short-circuiting with the other electrical and/or mechanical circuits in the transducer. In addition, the cylinder made a substantially rigid material may better support the two flexible surrounds so that the two surrounds do not induce wobbling in the diaphragm.
