PURPOSE:To obtain a speaker whose characteristic is not deteriorated even with a large input by providing a spider having corrugated part projected at a right angle to the circumferential direction to the rising part. CONSTITUTION:The spider supporting a cone of a speaker and holding the cone on a center axis of the speaker is provided with corrugated parts 15 projected in radial direction of a circular support part 13 at the rising part 14. Thus, the strength of the rising part 14 is increased and even when a large input is given to the speaker and a waveform part 12 is vibrated at a large amplitude, the support part 13 is held sufficiently. Thus, the speaker whose characteristic is not deteriorated even at a large input is obtained. |
