Abstract

A magnet system 4 defines an annular gap in which a coil 15 is mounted to move axially in the magnetic field. A former 16 for the coil is attached to a funnel-shaped diaphragm 18 which is mounted at its outer edge by a flexible ring 21 secured to a frame 2. In the region of the attachment point of the coil former, a first corrugated ring 19 attaches it to the magnet system 4 and in order to achieve greater security against tilting of the coil 15, there is provided at an axial distance from the plane of the first ring 19, a further corrugated ring 23, which is connected at least substantially rigidly to the coil former and to the magnet. Ring 23 may alternatively lie at a rearward extension of the coil former. <IMAGE>
