代码：

<style>
.ball { /* 球体 */
margin: auto; margin-top: 80px; width: 80px; height: 80px;
background: olive linear-gradient(135deg,rgba(0,250,0,.85),rgba(30,250,60,.95));
position: relative; border-radius: 50%;
filter: drop-shadow(2px 2px 6px rgba(0,0,0,.7));
transform: skew(2deg); cursor: pointer;
}
.ball::before, .ball::after { content: ''; position: absolute; } /* 伪元素：修饰 */
.ball::before { /* 伪元素一：高亮 */
left: 0; top: 0; width: 100%; height: 100%; border-radius: 50%;
background: radial-gradient(circle at 35% 40%,rgba(255,255,255,.75),rgba(0,0,0,.15));
}
.ball::after { /* 伪元素二：外边框 */
left: -30px; top: -30px; right: -30px; bottom: -30px;border: 10px solid #ccc;
border-radius: 20%; transform: rotate(45deg);
}
.ball div { /* 子元素共2个：动画 */
position: absolute; border: 10px solid rgba(0,0,0,.45); border-radius: 50%;
border-color: green lightgreen green darkgreen; opacity: .55;
}
.ball div:nth-child(1) { left: -10px; top: -10px; right: -10px; bottom: -10px; animation: rot 4s linear infinite;}
.ball div:nth-child(2) { left: -20px; top: -20px; right: -20px; bottom: -20px;animation: rot 12s linear infinite; }
@keyframes rot { to { transform: rotate(1turn); } } /* 动画转圈 */
</style>
<div class="ball">
<div></div>
<div></div>
</div>
<script>
let flag = true;
let ball = document.querySelector(".ball");
let au = document.createElement("audio");
au.src = "http://www.kumeiwp.com/sub/filestores/2022/04/18/cb7a4bda166a1721b18c3829d27f9a50.mp3";
au.autoplay = flag;
au.loop= true;
au.style.display = "none"
ball.appendChild(au);
ball.onclick = function(){
if(flag) {
Array.from(this.children).forEach(function(item){item.style.animationPlayState = "paused"; });
au.pause();
flag = false;
} else {
Array.from(this.children).forEach(function(item){item.style.animationPlayState = "running"; });
au.play();
flag = true;
}
}
</script>

不想要外边框的，删掉CSS外边框部分代码即可，即：

.ball::after { /* 伪元素二：外边框 */
left: -30px; top: -30px; right: -30px; bottom: -30px;border: 10px solid #ccc;
border-radius: 20%; transform: rotate(45deg);
}
