    Abstract: Loudspeakers are described that may reduce comb filtering effects perceived by a listener by either 1) moving transducers closer to a sound reflective surface (e.g., a baseplate, a tabletop or a floor) through vertical (height) or rotational adjustments of the transducers or 2) guiding sound produced by the transducers to be released into the listening area proximate to the reflective surface through the use of horns and openings that are at a prescribed distance from the reflective surface. The reduction of this distance between the reflective surface and the point at which sound emitted by the transducers is released into the listening area may lead to shorter reflected path that reduces comb filtering effects caused by reflected sounds that are delayed relative to the direct sound. Accordingly, the loudspeakers shown and described may be placed on reflective surfaces without severe audio coloration caused by reflected sounds.

    Abstract: An audio speaker having a suspension system including a surround to support a diaphragm within a frame and to reduce non-pistonic motion of the diaphragm at several resonant frequencies is disclosed. More particularly, embodiments of the surround include a film that undulates in a peripheral direction around the diaphragm and includes several undulations above and below a radial gap between the diaphragm and the frame. Other embodiments are also described and claimed.

    Abstract: A speaker driver including a frame and a magnet assembly positioned within the frame. A sound radiating surface may be suspended over the magnet assembly. The sound radiating surface may include a top face and a bottom face, and the bottom face may face the magnet assembly. A suspension member may suspend the sound radiating surface over the magnet assembly. The suspension member may include a top side connected to the bottom face of the sound radiating surface and a bottom side connected to the magnet assembly. A voice coil extends from the bottom face of the sound radiating surface.
