| titleOfInvention | METHOD FOR PRODUCING SPEAKER MEMBRANES |
| abstract | The invention relates to a chemical aid for Fasergusskoerper, especially for speaker membranes with molded hinge. It has set itself the task of making it possible to produce loudspeaker membranes with a low self-resonant frequency with improved stability of the hinge by adding the aid according to the invention. According to the invention, this object is achieved in that the chemical adjuvant consists of a high molecular weight fatty acid ester which is obtained by condensation reaction of a fatty acid mixture consisting predominantly of stearic acid with a tertiary amine, preferably triaethanolamine. |
