摘要： A shaker for transmitting vibrations to an application, the shaker having: a frame, including an application attachment surface for attaching the shaker to the application; a magnet unit configured to provide a magnetic field in an air gap; a coil assembly including a voice coil mounted to a voice coil former. The voice coil former is attached to the frame at a voice coil former attachment surface on the frame, wherein the voice coil former is configured to position the voice coil in the air gap, when the shaker is at rest; wherein the magnet unit is configured to move relative to the voice coil along a movement axis of the shaker when the shaker is activated by supplying electrical current to the voice coil; wherein the magnet unit is suspended from the frame by a suspension arrangement that includes a proximal suspension which interconnects the frame and the magnet unit and a distal suspension which interconnects the frame and the magnet unit, wherein the proximal suspension is closer to the voice coil former attachment surface on the frame than the distal suspension when the shaker is at rest. One of the proximal and distal suspensions has a stiffness K1, and the other of the proximal and distal suspensions has a stiffness K2, wherein K2 > K1, and the ratio K1 / K2 is 0.4 or less.

摘要： A loudspeaker comprising: a mounting frame; an acoustic radiator; a drive unit. The drive unit includes: a magnet assembly including a magnet unit configured to provide a magnetic field in an air gap, wherein the air gap extends around a movement axis of the inertial exciter; a coil assembly, and at least one drive unit suspension. The coil assembly includes: an attachment portion which provides an attachment between the coil assembly and the acoustic radiator; a voice coil; a voice coil former which extends from the attachment portion into the air gap, wherein the voice coil is mounted to the voice coil former so that the voice coil sits in the air gap when the drive unit is at rest; a tubular member, which is positioned radially outwardly of the voice coil former with respect to the movement axis, and which overlaps the voice coil former along at least a portion of the movement axis. The at least one drive unit suspension is attached to the tubular member and a part of the magnet assembly positioned radially outwardly of the tubular member so that the acoustic radiator is suspended from the magnet assembly via the coil assembly by the at least one drive unit suspension. The magnet unit assembly is suspended from the mounting frame by at least one mounting frame suspension.

摘要： L'invention concerne un excitateur (1) audio comprenant une bobine (2) électromagnétique et un circuit magnétique formé d'un corps (3) comprenant un noyau (3a) aimanté et un élément périphérique (3b) s'étendant autour du noyau pour former un entrefer. L'excitateur comprend une suspension (8) reliant la bobine au corps de sorte que la bobine se déplace par rapport au corps selon un axe longitudinal (AA') dans l'entrefer autour du noyau. L'excitateur comprend également un élément (4) de contact fixé sur une extrémité (2a) de la bobine qui recouvre l'ouverture (2b) de la bobine et qui comprend une face extérieure (5) destinée à être en contact avec une surface (S) à faire vibrer et une face intérieure (6) faisant face au noyau. La suspension s'étend de la face intérieure de l'élément de contact jusqu'au noyau pour fonctionner par compression lors d'un déplacement de la bobine par rapport au corps selon l'axe longitudinal.

摘要： An actuator includes a voice coil and a moving magnet assembly. The coil is attached to a panel extending in a plane. A first portion of the coil includes a first set of windings arranged in a spiral extending parallel to the plane. The first set of windings spans a first dimension in a first direction parallel to the plane. The first set of windings is attached to the panel. A second portion of the coil includes a second set of windings extending perpendicular to the plane. The second set of windings spans a second dimension in the first direction. The first dimension is larger than the second dimension. The magnet assembly is suspended from the panel, and includes a magnet positioned within the second portion of the coil. The magnet assembly is configured to vibrate in a second direction perpendicular to the plane during operation of the actuator.
