FIELD: technology for reproducing sound is used in audio systems, audio-video systems, and also in communication means like phones, radio and the like. ^ SUBSTANCE: device has at least one winding of electric wire in surrounding air environment, meant for forming micro-vibrations between coils, due to voltage difference between spirals of first and second layers. Each winding layer is wound on soft polymer base in same direction, and reverse wire is positioned along base. Device additionally has electro-acoustic filter, through which power is sent to winding. Additionally device has at least one magnet, positioned inside winding or one magnet, positioned outside winding. ^ EFFECT: better legibility of sound reproduction. ^ 3 cl, 2 dwg |
