Abstract
The utility model discloses a centering supporting sheet of high-foot arcs with varying radiuses, and a loudspeaker and a sound box. The centering supporting sheet comprises a through hole and arc-shaped grooves. The through hole is arranged in the middle part of the centering supporting sheet. The arc-shaped grooves are distributed around the periphery of the through hole. The radial cross section of the arc-shaped grooves presents to be a wave shape which comprises wave crests and wave troughs. Multiple closed curves are formed by all the wave crests and the wave troughs on the top part and the bottom part of the centering supporting sheet. The arc parts of the closed curves are formed by arcs which are not all equal in radiuses and connected in a head-to-tail manner. The edge of the centering supporting sheet extends outwardly so that a high foot is formed. According to the entering supporting sheet of the arcs with varying radiuses of the high foot, and the loudspeaker and the sound box, amplitude sound of loudspeaker pure tone detection can be avoided so that frequency response curve is flat and straight, distortion and unfavorable cases are lowered and thus product performance is enhanced.
