    摘要: Various implementations include loudspeaker drivers. In some aspects, an electro-acoustic driver includes: a cup section; a core section at least partially housed in the cup section, the core section including: a primary magnet; and a coin adjacent to the primary magnet; a bobbin surrounding the core section between the cup section and the core section, where the bobbin and the core section define an inner magnetic gap; a coil surrounding the bobbin and a portion of the core section; and a ferrofluid located at the inner magnetic gap, where the driver has an outer diameter less than or equal to approximately 10 millimeters.

    摘要: An acoustic device includes a resilient surround having a proportionately unequal distribution of half roll and inverted half roll segments. Half roll segments may be sized and located to provide additional clearance for internal components. Regions of transitional concavity may be sized and located to provide increased stiffness in one or more dimensions. Transitions between inversions of concavity may be smooth and free of localized inflexions.

    摘要: A loudspeaker includes an acoustic diaphragm, a lever, and an oscillatory force source for driving the lever in oscillatory, rotary motion about a pivot axis. The loudspeaker also includes a connector that couples the lever to the acoustic diaphragm. The connector includes a first rotary joint that defines a first rotary axis that is fixedly attached to the acoustic diaphragm, a second rotary joint that defines a second rotary axis that is fixedly attached to the lever, and a linkage coupling the first and second rotary joints. The connector allows for rotational and translational movement of the lever and the diaphragm relative to each other.
