如何在颤动中从静态方法更新状态？

class Vibrator:
    def __init__(self):
        self.state = "off"
        self.callback = None

    def set_callback(self, callback):
        self.callback = callback

    def start(self):
        # 模拟颤动过程
        self.state = "vibrating"
        # 颤动过程中调用回调函数或触发事件
        if self.callback:
            self.callback(self.state)
        # 或者触发事件
        # self.on_vibration(self.state)

    def stop(self):
        # 模拟停止颤动
        self.state = "off"
        if self.callback:
            self.callback(self.state)
        # 或者触发事件
        # self.on_vibration(self.state)

    # 回调函数方式
    def on_vibration(self, state):
        print("Vibration state:", state)

    # 事件驱动方式
    # def on_vibration(self, state):
    #     print("Vibration state:", state)

vibrator = Vibrator()

# 回调函数方式
vibrator.set_callback(vibrator.on_vibration)

# 事件驱动方式
# vibrator.on_vibration += vibrator.on_vibration

vibrator.start()
vibrator.stop()
