摘要： The present invention relates to a loudspeaker (1). The loudspeaker (1) includes: a U-yoke for holding a magnet having a base (12) with an upstanding side (14) around the perimeter of the base (12); a frame (20) having a ring (22) around the U-yoke, the ring having a U-shaped cross-section orientated with a base (24) of the U abutting the side (12) of the U-yoke; a dome shaped diaphragm (40) connected to the frame (20) by a resilient member (30) around the dome (40), the resilient member (30) and the dome (40) being suspended from the frame (20); a first cavity (70) defined by the dome (40), resilient member (30), frame (20) and U-yoke; an external wall (80) around the circumference of the frame (20), the external wall (80) sealing a top of the U-shaped cross-section of the ring (22) forming a second cavity (100) between the external wall (80) and the ring (22); a port (110) in the frame (20) between the first cavity (70) and second cavity (100), wherein the first cavity (70) and second cavity (100) and the port (110) form a Helmholtz resonator system. The shape of the frame (20) in combination with the external wall (80) allows a Helmholtz resonator system to be established within the existing footprint of the loudspeaker.

摘要： A low-profile speaker that includes a low-profile frame, and a first magnet assembly disposed in the low-profile frame. The first magnet assembly has a first cage and a plurality of magnets disposed in the first cage. The low-profile speaker also includes a support assembly having a cone and a support ring attached to the cone, and a voice coil attached to the support ring. The support ring and voice coil are suspended in relatively close proximity to the magnet assembly such that the support ring and voice coil oscillate in response to electrical signals in the voice coil.

摘要： An electrodynamic loudspeaker device comprising a chassis (1), a translatable body (3) and an actuator (11) arranged for moving the translatable body (3) with regard to the chassis (1). The translatable body (3) is provided with (1) a three-dimensional diaphragm body (5) having a contour (5C), a diaphragm base part (5b) and a diaphragm top part (5t) which is wider than said base part (5b), an axial axis (5a) extending from the one part to the other part and (2) a support body (7). The support body (7) has a bound support end portion (7b) fixed to the diaphragm base part (5b) and a free support end portion (7f) and extends substantially parallel to the axial axis (5a) and at least partly inside a space (9) enveloped by the contour (5C) of the diaphragm body (5). The actuator (11) comprises a stationary actuator part (11S) supported by the chassis (1) and a movable actuator part (11m) supported by the support body (7) and sited between both support end portions. These actuator parts are arranged for magnetically cooperating with each other across an air gap (13). The diaphragm top part (5t) is secured to the chassis (1) by means of a flexible suspension means (15) and the free support end portion (7f) is suspended from the chassis (1) by means of a flexible centering means (17) in order to provide a flat and during operation stable and resonance free device.

摘要： Erfindungsgemäß wird ein Lautsprecher (10) mit Flachmembran (11) angegeben, welcher sich durch eine geringe Einbautiefe und einen großen Hub auszeichnet, ohne daß die Gefahr des Taumelns besteht. Um dies zu realisieren, wird die Seite der Flachmembran (11), welche dem Antriebssystem (12) zugewandt ist, mit Stützmitteln (19) versehen. Diese Stützmittel (19) erstrecken sich im wesentlichen längs der Lautsprechermittelachse (16) in Richtung des Antriebssystems (12). Die Zentriermembran (18.2) ist mit dem Ende (20) des Stützmittels (19) verbunden, welches der Flachmembran (11) abgewandt ist. Um eine besonders gute Zentrierwirkung zu erzielen, sollten die von der Flachmembran (11) abgewandten Enden (20) der Stützmittel (19) einen möglichst großen radialen Abstand zur Lautsprechermittelachse (16) haben.
