FIELD: mechanical engineering. ^ SUBSTANCE: device has casing 1 with pole 2 mounted on bearing rod 3, and ring-shaped edge formed by internal 5 and external 6 surfaces, being in homothetic relation to each other. The edge is located around common rotation axis. Internal and external surfaces of this resonator are displaced relative to each other along the rotation axis in such a manner that thickness E exceeds thickness e near pole 2 along ring-shaped edge 4. ^ EFFECT: increased modal weight with relatively low working frequency being retained; simplified processing method. ^ 4 cl, 1 dwg |
