摘要： The present invention provides a loudspeaker driver not suffering from high levels of distortion caused by the non-linear stiffness commonly found with drivers that utilize progressive suspension elements. The novel suspension element for suspending the diaphragm of a loudspeaker driver to the chassis thereof has a geometry with two opposing first sections and two opposing second sections, which connect the two first sections. The second sections have a curvature radius smaller than that of the first sections. The mean height of the radial cross-sectional profile of the second section is higher than the height of the cross-sectional profile of the first sections. The first sections have an axial stiffness greater than the second sections.

摘要： The present invention relates to a loudspeaker including an enclosure having front portion, side portions and back portion defining an inner volume, the front portion is formed as a waveguide surface and includes at least one driver in the center of the waveguide surface and is capable to radiate the main acoustic power of the loudspeaker to ambient volume in direction of first acoustic axis, and an additional driver attached to the enclosure. In accordance with the invention the additional driver is attached inside the enclosure such that a sub volume is formed inside the inner volume, the sub volume limited by the driver, spacers between the driver and the front portion, and the front portion of the enclosure, and at least one port is adapted to open from the sub volume to ambient volume either to side portion or back portion of the enclosure.
