    摘要: A transducer for a hearing aid includes a housing, a relatively thin membrane having a free end suspended in the for vibration in response to a motor. The motor has a coil and a magnet assembly, the coil being mounted in the housing beneath the membrane; the magnet assembly being mounted in the housing coaxially with the coil and to one edge of the membrane.

    摘要: A receiver assembly includes a housing having a fixed housing portion and a shiftable housing portion cooperating to define a hollow cavity. A flexible membrane secured between the fixed housing portion and the shiftable housing portion and adapted to allow relative motion between the fixed and shfitable housing portions. The receiver assembly further includes a magnetic motor assembly including a displaceable drive rod; and a link assembly having a first end fixedly attached to an inner surface of the shiftable housing and a second end coupled to the drive rod. The link assembly translates the shiftable housing portion relative to the fixed housing portion in response to the displacement of the drive rod.

    摘要: A thin loudspeaker is provided that produces a superior frequency response and a diffuse acoustical pattern using magnetic drivers, acoustical plates, or a combination of magnetic drivers and acoustical plates. The invention contains a specially designed crossover network and a novel enclosure design. The novel enclosure includes a septum and cross bracing which enables the invention to realize superior performance in a thin loudspeaker design. The invention encompasses methods for improving the performance of an acoustical plate which include (1) placing acoustical plate motor elements on the plate in a manner that avoids rotational, mirror, and translational symmetry, (2) using acoustical plate motor elements of different shapes and sizes to stimulate the plate, and (3) using an acoustical plate that has an asymmetric shape. All of the embodiments of the invention may be covered with a decorative cover and hung on a wall like a picture or used to form a panel in a home entertainment center.

    摘要: A broad band loudspeaker (101) includes a diaphragm (103) driven by coil assembly (125) centered on a pole (131) of a magnet assembly (133) by a low-friction guide (127) depending from a lower end of the coil assembly, and a low-friction guide mounted on an upper end of the pole (131). A suspension (107) for the diaphragm (103) includes two or more parallel, resilient suspension members (115a, 115b), extending between the diaphragm (103) and frame (105) and mounted through a pair of resilient mounting pads (119a, 119b, 125a, 125b). The lower guide (127) includes a flexible portion (151a) which acts like a flapper valve of a pump to create a current of cooling air past down the inside of the coil assembly (125), up the outside of the coil assembly and then out of flux gap (130). Cooling fins (167) mounted on an upper side of the magnet assembly (133) promote transfer of heat to the inside of enclosure (121) and are arranged for the current of air from the flux gap to flow past the fins and into an enclosure (121).

    摘要: An inductively activated loudspeaker produces sound by inducing an oscillating current in a shorted turn conductive tube that is positioned within a focused magnetic field. The loudspeaker includes an electrically excitable stationary coil positioned within the magnetic field and in inductive relation to the conductive cylinder. The oscillation of current within the stationary coil induces a corresponding oscillating current in the cylinder, which causes the cylinder to physically oscillate within the defined magnetic field. The resultant vibratory movement of the diaphragm, upon which the cylinder is mounted, has the effect of creating sound. Also disclosed is a combined stationary coil and outer pole assembly with internalized heat sinking, and which separably attaches to the remainder of the magnetic assembly of the loudspeaker.
