Abstract
An electroacoustic transducer operating in accordance with the electrodynamic principle include a diaphragm which has in the region of the coil an annular protrusion which is integrally connected to the diaphragm, wherein the coil is attached, preferably glued, to the annular protrusion at a desired distance from the diaphragm. The attachment can be end face against end face. The diaphragm may in the area of the coil have an annular reinforcing corrugation which is attached to the coil in an appropriate manner, preferably by gluing.
Claims5
An electroacoustic transducer operating in accordance with the electrodynamic principle, the transducer comprising a diaphragm, a coil connected to the diaphragm, wherein the coil projects into an annular slot between poles of a magnet system, wherein an initial foil for manufacturing the diaphragm has a thickness of 20-80 micrometers, the diaphragm comprising an annular protrusion integrally formed with the diaphragm, wherein the annular protrusion projects from a side of the diaphragm facing the magnet system and has an end face facing the magnet system, wherein the coil is attached to the end face of the annular protrusion and projects away from the annular protrusion, and wherein the annular protrusion has a groove-shaped cross-section.
