<p>The magnet part and the coil-diaphragm part are made in separate steps and are then assembled. The coil-diaphragm part is made in a plurality of successive stations; first a plane diaphragm material is adhered to one side of the carrier ring [10], and then a heat activatable glue is applied to the diaphragm in the region where the coil [15] is to be attached, and finally the diaphragm is formed with a heat emitting tool simultaneously with the coil [15] being pressed against the heat activated glue. …<??>The transducer has a diaphragm [13] connected to a coil [15] which is movable in a slit [6] between the pole shoes [3, 4] of a magnet [5], the pole shoes [3, 4] being fitted coaxially on a guide pin [2]. To provide for exact centering of the coil [15] in the slit [6], a carrier ring [10], to which the diaphragm [13] is secured so that the coil [15] is concentric with the carrier ring [10], engages an outwardly facing, annular face [12] of the outermost pole shoe [3].</p> |
