Abstract
A loudspeaker having a first magnet configured to output a first magnetic field in a first magnet gap, an elongate armature extending through the first magnet gap, a first coil configured to generate a magnetic flux in the armature, a first diaphragm, a first element configured to transfer force and/or movement from the armature to the first diaphragm, a base and a first and a second support element, the first support element connecting the armature to the base at a first longitudinal position at a first side of a predetermined portion along the length of the armature, and the second support element connecting the armature to the base at a second longitudinal position at a second, opposite side of the predetermined portion. The base may flex between a U-shape and an inverted U-shape and may thus provide force to move the diaphragm.
