Abstract: The loudspeaker construction comprises a loudspeaker chamber delimited by a loudspeaker enclosure structure, a reflex duct communicating with the loudspeaker chamber so as to connect the loudspeaker chamber to the exterior environment of the loudspeaker enclosure, and at least one loudspeaker unit mounted on the loudspeaker enclosure structure so as to form a portion of the delimiting walls of the loudspeaker chamber. According to the invention, the loudspeaker enclosure structure comprises a curved spiral structure closed from its both sides by gable elements so as to form the loudspeaker chamber, and the reflex duct is adapted at least partially running on the outer periphery of the spiral structure.
Abstract: The invention relates to a reflex loudspeaker construction (1, 2, 3), which comprises a loudspeaker chamber (30) delimited by the reflex loudspeaker construction (1, 2, 3), a reflex channel (5) connected to the loudspeaker chamber (30), which connects the loudspeaker chamber (30) to the external space of the reflex loudspeaker construction (1, 2, 3), and at least one loudspeaker element (7) connected to the reflex loudspeaker construction (1, 2, 3), which forms part of the structure delimiting the loudspeaker chamber (30). According to the invention, the reflex loudspeaker construction (1, 2, 3) comprises at least two components (2, 3), which can be repeatedly detached at least partly from each other, without dismantling, in order to use the loudspeaker chamber (30) as a transportation space.
Abstract: The present invention relates to a bass-reflex loudspeaker construction and a method of manufacturing the same. The loudspeaker construction comprises a loudspeaker chamber (7) delimited by a loudspeaker enclosure structure (1, 2, 8), a reflex duct (4) communicating with the loudspeaker chamber (7) so as to connect the loudspeaker chamber to the exterior environment of the loudspeaker enclosure, and at least one loudspeaker unit (3) mounted on the loudspeaker enclosure structure (1, 2, 8) so as to form a portion of the delimiting walls of the loudspeaker chamber (7). According to the invention, the loudspeaker enclosure structure comprises a curved spiral structure (1) closed from its both sides by gable elements (2, 8) so as to form the loudspeaker chamber (7), and the reflex duct (4) is adapted at least partially running on the outer periphery of the spiral structure (1).
Abstract: A nested compound loudspeaker comprising a speaker assembly chassis (11), an outer driver (18) connected to the speaker assembly chassis (11) and having an inner edge, which defines an opening in the outer driver (18) and forms a functional edge (20), and an inner driver (8) connected to the speaker assembly chassis (11) and at least partially surrounded by the opening of the outer driver (18) and the inner driver (8) having an acoustical centre axis located at a distance (r) from the functional edge (20) in a radial direction (?). The distance (r) is non-constant around the acoustical centre axis, wherein the distance (r) has a first value in a first radial direction (?) and a second value different to the first value in a second radial direction (?).

Abstract: 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.

Abstract: 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.
