Zusammenfassung:	A surround structure includes an inner rim, an outer rim, and a wave-shaped elastic protrusion, disposed between the inner rim and the outer rim. The wave-shaped elastic protrusion is integrally formed by a plurality of arc-shaped parts. Each arc-shaped part includes a first end, a second end, and a middle part between the first end and the second end. A radial section of each arc-shaped part is arcuate and includes a top edge and two arc-shaped segments combined with two sides of the top edge. A curvature of a radial section of each arc-shaped segment from the first end to the middle part gradually decreases, a curvature of a radial section of each arc-shaped segment from the middle part to the second end gradually increases, and a shape of a radial section of the first end is the same as a shape of a radial section of the second end.
