首先对DeviceMotionEvent进行优化；

去除没用的代码，又一次封装DeviceMotionEven

if(window.DeviceMotionEvent) {

	var speed = 25;//定义一个数值

	var x = y = z = lastX = lastY = lastZ = 0;//重置全部数值

	window.addEventListener('devicemotion', function(){

		var acceleration =event.accelerationIncludingGravity;//将传感值赋给acceleration

		x = acceleration.x;

		y = acceleration.y;

		z = acceleration.z;

		if(Math.abs(x-lastX) > speed || Math.abs(y-lastY) > speed ) {

			// TODO:在此处能够实现摇一摇之后所要进行的数据逻辑操作

				 donghua();

		}

		lastX = x;

		lastY = y;

		lastZ = z;

	}, false);

}

因为实际项目中有非常多需求无法非常好的实现。

比方：动画不运行完成就不能继续运行DeviceMotionEvent事件；

所以做了进一步优化；

var f=1;

function donghua(){

	//动画事件

	$(".img").animate({left:'0',opacity:'1'},700,function(){f=1;});

}）。

if(window.DeviceMotionEvent) {

	var speed = 25;//定义一个数值

	var x = y = z = lastX = lastY = lastZ = 0;//重置全部数值

	window.addEventListener('devicemotion', function(){

		var acceleration =event.accelerationIncludingGravity;//将传感值赋给acceleration

		x = acceleration.x;

		y = acceleration.y;

		z = acceleration.z;

		if(Math.abs(x-lastX) > speed || Math.abs(y-lastY) > speed ) {

			// TODO:在此处能够实现摇一摇之后所要进行的数据逻辑操作

			 if(f==1){

				 donghua();

				 f=0;

			}

		}

		lastX = x;

		lastY = y;

		lastZ = z;

	}, false);

}

如今就完美了
