摘要： A speaker apparatus capable of operating in a large amplitude regime by minimizing magnetic loss, is provided. The speaker device includes a magnet configured to generate a magnetic flux, a pole piece configured to form a path of the magnetic flux generated by the magnet, a back plate provided at a lower end of the pole piece to support the magnet, and a plate provided to form a magnetic gap between the plate and the pole piece. Several plates may be provided so that the magnetic gap is expanded to enlarge amplitude of output sound.

摘要： An apparatus includes at least one load and a plurality of armatures, each including a permanent magnet, which are coupled to the at least one load to cause the at least one load to move. The apparatus also includes a common stator that defines an air gap within which the plurality of armatures is disposed. The common stator is configured for creating magnetic flux across the air gap for the armatures to interact with, thereby to drive motion of the at least one load.

摘要： An improved electromagnetic actuator which is provided with a coil (10) for impressing current, a magnet (20) which forms a magnetic circuit while keeping a magnetic gap (G) against a magnetic yoke (21), a diaphragm (11) which oscillates when a high-frequency current is impressed, and another diaphragm (22) which oscillates when a low-frequency current is impressed and wherein each section is housed in an enclosure (3) with the coil (10) being arranged in the magnetic gap (G). In one of the embodiments, a bottom plate composed of radially oriented magnets, diaphragms with a double-suspended structure, and a magnetic shield member is attached to the enclosure so as to suppress the leakage of magnetic fluxes from the enclosure and elastic packings (5 and 7) are put not only between the enclosure of the actuator and the housing case of portable electronic equipment, but also between the enclosure of the actuator and a mounting substrate so as to further improve the frequency characteristics of the actuator from the side of the mounting structure of the actuator.
