[0028] In some optional embodiments, the bottom surface of the wave spring 13 is flush with the upper surface of the side wall 101. The basket 10 can be made very thin, and the side wall 101 will be correspondingly low, so that the bottom surface of the wave spring 13 is flush with the upper surface of the side wall 101, which can avoid the wave spring 13 from touching the basket 10 when it is displaced downward, thereby affecting the sound quality.
[0029] In some alternative embodiments, the outer side of the upper surface of the side wall 101 has a convex ridge 102. The outer edge of the rubber pad 13 can be bonded to the upper surface of the side wall 101 by glue, and the convex ridge 102 can prevent the glue from overflowing. In addition, the convex ridge 102 can also help prevent the outer edge of the rubber pad 13 from being raised.
[0030] In some alternative embodiments, the inner side of the drum paper 12 extends downwardly and connects to the voice coil; and the outer side of the drum paper 12 extends downwardly perpendicularly and connects to the rubber pad 13.
