Electronic circuit and in-ear piece for a hearing device

The invention relates to a method for controlling a controllable acoustic valve of a heating device. The controllable acoustic valve includes a movable valve element that is in one of at least two basic stable states, wherein the movable valve element is configured to be maintained in each basic stable state by holding force, and a neutral point on which the holding force is substantially counteracted exists between the at least two basic stable states. The method includes supplying first driving signals to the controllable acoustic valve to overcome holding force of the first basic stable state so as to initiate switching of the movable valve element from the first basic stable state to the second basic stable state, wherein the first driving signals can allow the movable valve element toleave the first basic stable state and pass through the neutral point between the first and second basic stable states. 本发明涉及用于控制听力设备的可控声阀的方法，可控声阀包括适合于置于至少两种基本稳定状态的一种中的可移动阀元件，其中可移动阀元件被配置为由保持力维持在基本稳定状态的每种中，并且其中基本上抵消保持力的中性点存在于
