ACOUSTIC TRANSMITTER OF ELECTROMAGNETIC TYPE, CONSTRUCTED BY THE MAGNETIC CIRCUIT DIAGRAM WITH THE DISTRIBUTION OF FLOWS

摘要

The invention relates to the field of electromagnetic type acoustic transducers. An electromagnetic-type acoustic transducer with a corrugated permalloy membrane of grade 79NM, diameter 5.6 mm, thickness 0.02 mm, with a supmembrane volume of 12.06 mm, while in the construction of the magnetic system of the capsule one magnet from an alloy of the brand UNDK35T5BA with a volume of 27.7 mm one coil with a number of turns 600, an electrical resistance of 57 Ohms, made wire PEVTLK-0.05. EFFECT: reduction of dimensions and preservation of sensitivity of a small-sized acoustic transducer of electromagnetic type. 1 ill.
