uniapp语音时的动态音波的实现

一、实现效果

该文做出来的效果：图片中的音波是动态的

二、实现代码

将它写为一个组件，方便之后用。命名为“audioWave.vue”

<template>
	<view class="audio-wave">
		<view class="wave-bar" v-for="i in 10" :key="i"></view>
	</view>
</template>
<script setup lang="ts">

</script>
<style lang="scss">
	.audio-wave {
		position: absolute;
		left: 0;
		top: 50%;
		transform: translateY(-50%);
		width: 100%;
		height: 40rpx;
		display: flex;
		align-items: center;
		justify-content: center;
		gap: 6rpx;
	}

	.wave-bar {
		width: 4rpx;
		height: 20rpx;
		background-color: #FFFFFF;
		border-radius: 2rpx;
		animation: waveAnimation 1s ease-in-out infinite;
		opacity: 0.8;
	}

	.wave-bar:nth-child(1) {
		animation-delay: 0s;
	}

	.wave-bar:nth-child(2) {
		animation-delay: 0.1s;
	}

	.wave-bar:nth-child(3) {
		animation-delay: 0.2s;
	}

	.wave-bar:nth-child(4) {
		animation-delay: 0.3s;
	}

	.wave-bar:nth-child(5) {
		animation-delay: 0.4s;
	}

	.wave-bar:nth-child(6) {
		animation-delay: 0.5s;
	}

	.wave-bar:nth-child(7) {
		animation-delay: 0.6s;
	}

	.wave-bar:nth-child(8) {
		animation-delay: 0.7s;
	}

	.wave-bar:nth-child(9) {
		animation-delay: 0.8s;
	}

	.wave-bar:nth-child(10) {
		animation-delay: 0.9s;
	}

	@keyframes waveAnimation {

		0%,
		100% {
			height: 20rpx;
		}

		50% {
			height: 40rpx;
		}
	}
</style>
