Patent number: 9838793Abstract: 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.Type: GrantFiled: June 14, 2013Date of Patent: December 5, 2017Assignee: Genelec OyInventors: Stephen Millar, Jaakko Nisula, Jussi Väisänen, Ilpo Martikainen

Patent number: 9462373Abstract: The present invention provides an improved loudspeaker enclosure comprising two opposing end sections arranged at a distance from each other and enclosing sections which connect the end sections over said distance, wherein the inner volume of the enclosure is defined by said sections. The enclosure also has a reflex port which comprises a reflex opening which is provided to the enclosure and adapted to exhaust internal pressure from the inner volume to outside the enclosure. The reflex port further comprises an inner reflex port former which connects the inner volume of the enclosure to the reflex opening for forming the reflex port. The reflex port former is formed by molding as an integral inner wall section which extends inwards from the inner surface of either or both end section.Type: GrantFiled: April 2, 2013Date of Patent: October 4, 2016Assignee: Genelec OyInventors: Markku Kulomäki, Siamäk Naghian, Jussi Väisänen, Ilpo Martikainen, Harri Koskinen
