Abstract: Embodiments are disclosed of a speaker capable of producing multi-frequency-range sound using bar magnets, multiple diaphragms, and a shared planar voice coil. The planar voice coil is located between the bar magnets and translates a received electric signal into the kinetic energy that vibrates the diaphragms, thus reproducing multi-frequency range sound. In some embodiments, the speaker generates bi-directional sound.

Abstract: Disclosed are numerous embodiments of speakers of non-conventional shape. In one set of embodiments, each speaker comprises a pair of curved magnets and a curved voice coil plate located between the magnets and parallel to the magnets. In another set of embodiments, each speaker comprises two or more segments attached at an angle to one another, where each segment comprises a pair of bar magnets and a voice coil plate located between the magnets. Optionally, the magnets and voice coil plate can be curved or angled in a third-dimension as well. The embodiments allow for a speaker to be built of almost any shape.
