具体的，参照图4和图5，图4表明了几个大的模块之间的连接关系和通讯关系，图5详细地表述了其中的连接关系。继续参 照图5，室内采音器与每个不同固定系数的室内滤波器连接，不同固定系数的室内滤波器中的一个通过电路切换模块与室内主动降噪处理模块连接，中央处理器能够给室内主动降噪处理模块传递需要的信息，使室内主动降噪处理模块反过来控制电路切换模块选择性地连接到合适的室内滤波器上，图5中实线表述目前的连接关系，虚线表示可以进行切换的连接关系，确保室内主动降噪处理模块始终与其中一个不同固定系数的室内滤波器连接，且可以进行切换。
整体工作过程可以通过主动降噪空调器的控制方法来体现，如图6所示，主动降噪空调器的控制方法包括：
S100、中央处理器获取室内机的风机转速并通信传输至室内主动降噪处理模块；
S200、控制所述室内主动降噪处理模块切换电路切换模块，从而连接到与风机转速对应的固定系数的室内滤波器上。
对于室内机而言，最主要的噪音来源便是室内机的风机在旋转时产生的，而室内机的风机转速不同，所产生的噪音的频率也不同，这就意味着不同风机转速应当有不同固定系数的室内滤波器进行处理，如果统一规定为一种固定系数的室内滤波器可能起不到很好的滤波作用，这便会影响到主动降噪处理模块进行后续降噪工作。因此，首先通过中央处理器获取室内机的风机转速并通信传输给室内主动降噪处理模块，从而能够使室内主动降噪处理模块选择最合适的固定系数的室内滤波器进行滤波，也就是通过切换电路切换模块来实现不同室内滤波器的选择。
S300、控制室内主动降噪处理模块接收由室内采音器收集且经固定系数的室内滤波器过滤的噪音；
S400、控制室内主动降噪处理模块实时处理接收到的噪音，并生成降噪音波输出信号，传输至室内扬声器。
当室内滤波器完成过滤后，剩下的噪音即为需要单独处理的低频噪音，将这些噪音传入主动降噪处理模块后，能够转换成电路信号，并生成相反的降噪音波输出信号，传输至扬声器，扬声器便发出与低频部分的噪音相反的低频音波，两者谐波相互叠加后抵消，从而完成了室内机的低频噪音的清除。
S410、每隔△T1时间，重新返回步骤S100。
由于室内机风机转速并不是不变的，为了使主动降噪空调器的降噪能力增强，每隔△T1时间便重复一遍，重新确定是否需要重新选择室内滤波器，以达到最好的降噪效果。优选地，△T1时间为20秒，这样既不会频繁切换电路，也不会由于间隔时间过长导致中间时间段内低频噪音持续存在，使整体室内机工作状态较为均衡。
上面描述的均为对室内机的低频噪音进行处理，然而在室外机上，同样会产生低频噪音，这些噪音能够穿透墙壁或窗户进入室内，因此，消除室外机的噪音也相当重要，本发明还提供了一种主动降噪空调器，如图1和图3所示，包括室外机2、室内机1以及位于室内机1内部的中央处理器(未示出)，室外机2还包括依次连接的室外采音器21、室外滤波器(未示出)、室外主动降噪处理模块(未示出)和室外扬声器22，中央处理器与室外主动降噪处理模块通信连接，主动降噪空调器为变频空调器，室外滤波器由多个不同固定系数的室外滤波器组成，室外采音器21与所有不同固定系数的室外滤波器连接，室外主动降噪处理模块通过电路切换模块与其中一个系数的室外滤波器连接。
当主动降噪空调器为变频空调器时，室外机内的压缩机频率是随着不同需求而变化的，这就会产生变化的低频噪音，因此，基于与室内机相似的结构，其控制方法也相似，如图7至图9所示，主要包括：
S500、中央处理器获取室外机的压缩机频率并通信传输至室外主动降噪处理模块；
S600、控制室外主动降噪处理模块切换电路切换模块，从而连接到与压缩机频率对应的固定系数的室外滤波器上；
S700、控制室外主动降噪处理模块接收由室外采音器收集且经固定系数的室外滤波器过滤的噪音；
S800、控制室外主动降噪处理模块实时处理接收到的噪音，并生成降噪音波输出信号，传输至室外扬声器；
S810、每隔△T2时间，重新返回步骤S500。
其原理与S100-S410相同，不再赘述。
另外，本发明还提供了一种主动降噪空调器，如图1、图3、图10和图11所示，包括室外机2、室内机1以及位于室内机1内 部的中央处理器(未示出)，室外机2还包括依次连接的室外采音器21、室外滤波器(未示出)、室外主动降噪处理模块(未示出)和室外扬声器22，中央处理器与室外主动降噪处理模块通信连接，主动降噪空调器为定频空调器，室外滤波器为一种与定频空调器的压缩机频率对应的固定系数的室外滤波器。
当主动降噪空调器为定频空调器时，室外机内的压缩机频率恒定，这时所产生的低频噪音也是恒定的，对于固定系数的室外滤波器便不再需要进行选择，其控制方法也相应地去掉了中央处理器的实时反馈以及电路切换模块的切换，上述空调器的控制方法包括：
S900、中央处理器获取室外机的压缩机频率并通信传输至室外主动降噪处理模块；
S1000、控制室外主动降噪处理模块接收由室外采音器收集且经固定系数的室外滤波器过滤的噪音；
S1100、控制室外主动降噪处理模块实时处理接收到的噪音，并生成降噪音波输出信号，传输至室外扬声器；
S1110、每隔△T3时间，重新返回步骤S900。
此处需要说明的是，虽然压缩机频率理论上是不变的，但仍然在步骤S900中进行了一次确认，以便当压缩机出现故障或者压缩机频率随着使用年限的增加而老化造成的压缩机频率不准时，能够第一时间发现，以避免其与固定系数的室外滤波器不匹配造成的降噪不成功的情况。另外，仍然保留步骤S1110，是因为虽然定频空调器的压缩频率不会改变，但当其从开启状态转换为关闭状态后，若不进行检测，可能导致室外扬声器仍然进行降噪音波的输出，此时降噪音波便成了噪音源，这是发明人不希望看到的，因此增加步骤S1110，当定频空调器不进行工作时，使室外扬声器也不进行工作。
需要说明的是，上述实施方式仅仅用来阐述本发明的原理，并非旨在与限制本发明的保护范围，在不偏离本发明原理的条件下，本领域技术人员能够对上述结构进行调整，以便本发明能够应用于更加具体的应用场景。
例如，室内采音器11和室外采音器21为麦克风，当然还可以是其它可以进行音量收集工作的电器元件或者组件等；室内扬声器12和室外扬声器22为HIFI音响，当然还可以是其它可以传递降噪音波 的普通音响或者其它设备等；电路切换模块优选为转换开关，当然还可以是其它可以切换电路连通的电器元件或者组件等，这些都不偏离本发明的原理，因此都将落入本发明的保护范围之内。
本领域技术人员可以理解，上述衣物处理设备还包括一些其他公知结构，例如处理器、控制器、存储器等，其中，存储器包括但不限于随机存储器、闪存、只读存储器、可编程只读存储器、易失性存储器、非易失性存储器、串行存储器、并行存储器或寄存器等，处理器包括但不限于CPLD/FPGA、DSP、ARM处理器、MIPS处理器等。为了不必要地模糊本公开的实施例，这些公知的结构未在附图中示出。
上述实施例中虽然将各个步骤按照上述先后次序的方式进行了描述，但是本领域技术人员可以理解，为了实现本实施例的效果，不同的步骤之间不必按照这样的次序执行，其可以同时(并行)执行或以颠倒的次序执行，这些简单的变化都在本发明的保护范围之内。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
