1、创建音频并播放

export default {
	data() {
		return {
			audio: null
		}
	},
	onLoad(option) {
		// 获取音频文件路径
		const audioPath = '/static/audio/warn.mp3';
		// 创建并播放音频对象
		this.audio = uni.createInnerAudioContext();
		this.audio.src = audioPath;
		this.audio.autoplay = true;

		// 隐藏音频控件
		this.audio.obeyMuteSwitch = false;
		this.audio.loop = true;
		this.audio.onError((res) => {
			console.log('onError', res.errMsg);
		});
	},
        onUnload() {
		// 停止音频播放并销毁音频对象
		this.audio.stop();
		this.audio.destroy();
	},
}

2、解决IOS无法播放音频问题

var music = wx.setInnerAudioOption({
	obeyMuteSwitch: false,
	success: function(res) {
		console.log("开启静音模式下播放音乐的功能");
	},
	fail: function(err) {
		console.log("静音设置失败");
	},
});
