The invention discloses a terminal accessory and a terminal assembly realizing active noise reduction. The terminal accessory comprises an accessory main body, and a first microphone arranged at the position, close to a telephone receiver, on the accessory main body, and used for picking up environmental noise signals so as to realize noise reduction by matching with the telephone receiver. According to the scheme, an ANC microphone arranged on the terminal in the prior art is arranged on the terminal accessory, a microphone input pathway of a headphone jack is reused, so that the microphone stacking space and input pathway of the terminal are not occupied while the ANC function is realized, thus the stacking difficulty is reduced, the terminal design difficulty and cost are reduced, and space for choosing the ANC function is provided for users. 本发明公开了种实现主动降噪的终端配件及终端组件，所述终端配件包括配件主体和设置于所述配件主体靠近听筒的位置，用于拾取环境噪声信号以配合听筒实现降噪的第麦克风。本发明通过将现有技术中设置于终端上的ANC麦克风设置于终端配件，并复用耳机接口的麦克风输入通路，在实现ANC功能的同时不占用终端的麦克风堆叠空间和输入通路，降低了堆叠的难度，
