Abstract

PURPOSE:To reduce the distortion due to support system and high frequency, by switching the elongation of the damper due to the displacement of coil bobbin with the folded parts of each piece constituting the damper. CONSTITUTION:At the center of the damper 20, a ring 21 inserted with the coil bobbin is provided. A plurality of slits 22 formed radially are formed at the external circumference of the ring 21, and the slit 25 sections the circular plate into a plurality of sectors 23a-23h. The external circumference of the sector piece 23a is split into two to form the split pieces 26a, 26b. Further, linear folded parts 27a, 27b are formed at the boundary between the common piece 28 at the center side of the piece 23a and the sectors 26a, 26b. The folded part 31 is formed at the boundary between the common piece 28 and the ring 21, and the folded parts 32a, 32b are formed at the boundary between the split pieces 26a, 26b and the ring 24.
