附图简要说明
附图用来提供对本发明的进一步理解，并且构成说明书的一部分，与本发 明实施例一起用于解释本发明，并不构成对本发明的限制。在附图中：
图1为本发明实施例提供的一种运动速度的测试方法的流程图；

需要说明的是，所述压力孔可以配合移动设备的设计结构专门设置，也可以将移动设备本身的其他开口，例如耳机孔、电源孔或其他连接外界的开口作为本实施例中的压力孔，以使移动设备外观简洁美观。

具体的，运动速度获取单元23进一步用于，
根据公式v＝vr+vf·cosθ计算当前的运动速度v，其中θ为运动方向偏离风向的角度，取值范围为[0°，360°]；在实际应用中可以通过陀螺仪等设备测得运动方向偏离风向的角度，从而获得在任何风向状态下的运动速度，保证计算结果的准确度。
此外，运动速度获取单元23还可以进一步用于，逆风运动时，根据公式v＝vr-vf计算出当前的运动速度v；顺风运动时，根据公式v＝vr+vf计算出当前的运动速度v。
