摘要： An electromagnetic transducer such as an audio speaker, having a motor structure in which a shorting ring that sinks eddy currents also serves as a permanent fixture to provide coaxial alignment of two or more components within the transducer. These components could include various combinations of the yoke, the top plate, the magnet, and/or other parts. Ideally, the shorting ring extends axially as close as possible to the voice coil, to a position immediately adjacent the magnetic air gap.

摘要： An electromagnetic transducer, such as an audio loudspeaker, having an underhung voice coil disposed in a magnetically tapered air gap. The taper provides asymmetry in the magnetic flux field. As the voice coil moves in one direction, the motor becomes stronger and more efficient, and as the voice coil moves in the other direction, the motor becomes weaker and less efficient. This results in an increase in even-order harmonics. The magnetic taper may result from a geometric taper of one or both of the opposing steel pieces which form the gap, or it may result from one or both of them having an at least partially laminated structure. The geometric taper provides a magnetic reluctance gradient along the height of the magnetic air gap. The laminated structure provides a magnetic reluctance gradient through the thickness of the laminated member (e.g. top plate). The magnetic reluctance gradient produces a magnetic flux density gradient along the height of the magnetic air gap.
摘要翻译： 诸如音频扬声器的电磁换能器具有设置在磁锥形气隙中的底音音圈。 锥度提供磁通场中的不对称性。 当音圈沿一个方向移动时，电机变得更强大，效率更高，随着音圈向另一个方向移动，电动机变得更弱，效率更低。 这导致偶次谐波的增加。 磁性锥度可以由形成间隙的一个或两个相对的钢片的几何锥形产生，或者它们可能由其中一个或两个具有至少部分层压的结构产生。 几何锥度沿着磁性气隙的高度提供磁阻梯度。 层压结构通过层压构件（例如顶板）的厚度提供磁阻梯度。 磁阻梯度沿着磁隙的高度产生磁通密度梯度。

摘要： A disk drive including two or more spindles each carrying one or more media platters. The disk drive may have an industry standard sized chassis. By using reduced diameter platters, two spindles' platters can be fit within the chassis, increasing the capacity and/or performance of the drive. The two spindles' platters may be of the same type, such as magnetic hard disk platters, or they may be different, such as one spindle of hard disk and one spindle of optical disk. Optionally, one spindle's platter may be used as a cache or buffer for the other spindle's platter.

摘要： An audio speaker driver having a voice coil with graduated windings such that different sections of the voice coil have different electrical resistances and/or lengths per unit of height of the voice coil. A center portion of the voice coil gives a greater BL, while outer portions give lower overall electrical resistance, such that the audio speaker driver is highly efficient and linear during low excursion operation, with a smoother transition from the linear region to the grossly non-linear region. The wire of the graduated voice coil can have varying cross-sectional area over its length, can be wound on varying on-center spacing, can be wound in different numbers of layers in the various sections, and/or it can fork into interlaced, parallel windings.

摘要： A thermally conductive chimney tube extends through a loudspeaker cabinet that encloses a volume of air heated by a speaker driver. The open ends of the chimney are outside the cabinet. A column of air within the chimney is in contact with the external ambient air, but sealed off from the enclosed volume of air. As the speaker driver heats the enclosed volume of air, the material of the chimney transfers the heat to the column of air, which rises and carries the heat away into the external ambient air, cooling the inside of the loudspeaker cabinet and thus cooling the speaker driver.

摘要： An electromagnetic transducer such as an audio speaker which includes an asymmetric diaphragm to deliver smooth frequency response with reduced distortion by reduction of common modes in the diaphragm. Other benefits such as asymmetric directivity patterns can be realized. The asymmetric cone has a perimeter OD at which a surround may be coupled, and an ID at which a bobbin or spacer may be coupled. The center of the ID is not coincident with the center of the OD. The transducer further includes a stabilization mechanism for reducing rocking of the diaphragm assembly. The stabilization mechanism may include mass balancing of the diaphragm and/or adjustments to the location or symmetry of the suspension components.

摘要： An electromagnetic transducer such as an audio speaker, having three or more voice coils disposed in one or more magnetic air gaps. The voice coils can be combined in any permutation of series/parallel connections, to select any one of a predetermined set of impedance values for the transducer. Optionally, the transducer is equipped with a set of different terminal connector plugs, each of which automatically performs the series/parallel connections for its designated impedance value. All voice coils may be selected as active, allowing for a constant maximum efficiency, regardless of which impedance option is selected.
