摘要： Acoustic transducer comprises an upper part (301) and a lower part (302), with a first permanent magnet (303) in the upper part (301) and a second permanent magnet (304) in the lower part (302). Similarly named magnetic poles of the first and second permanent magnets (303, 304) face each other. An upper cover (306) in the upper part (301) and a lower cover (307) in the lower part (302) comprise magnetic material and define an enclosure around the magnets (303, 304). A coil (308) creates, under influence of an electric current, dynamic magnetic forces. A separating gap (309) between edges of said upper cover (306) and lower cover (307) is directed so that it allows a relative movement of the edges of said lower cover (307) and said upper cover (306) between different positions, said positions differing in the extent to which the edges of said upper cover (306) and lower cover (307) coincide.

摘要： Electroacoustic drivers that can be utilized in loudspeaker systems that utilize drivers having a magnetic negative spring (MNS) (such as reluctance assist drivers (RAD) and permanent magnet crown (PMC) drivers). The electroacoustic drivers can be used at all audio frequencies, including subwoofer frequencies. The magnetic negative springs of the electroacoustic drivers can cancel, or partially cancel, the large pressure forces on a sound panel (of an audio speaker) so that substantial subwoofer notes can be efficiently and cost effectively produced in small/portable speakers. The electroacoustic drivers can include a stabilizing/centering mechanism to overcome the destabilizing forces of a MNS that are too large for a voice coil alone to produce.

摘要： A device includes: a panel and an electromagnetic actuator mechanically coupled to a rear side of the panel to form a panel audio loudspeaker, the electromagnetic actuator comprising a coil attached to the rear side of the panel and a magnet suspended with respect to the coil via one or more spring elements, the coil defining an axis, wherein during operation of the device an electric current through the coil varies a relative displacement of the magnet with respect to the coil along the axis. The device includes: a chassis supporting the panel, the chassis comprising a housing for the device, the housing comprising a rear panel on an opposite side of the device from the panel; and a grounding assembly positioned along the axis between the magnet and the rear panel of the device, wherein the grounding assembly mechanically grounds the magnet to the chassis.
