Abstract
A noise-suppressing receiver is provided. A noise pick-up and a receiver are fixed within a cylinder-like body. An insulation layer is set between the noise pick-up and the receiver. The insulation layer divides the cylinder-like body into a receiver module and a noise-collecting module. A reticulate cover is provided at an end of the cylinder-like body, and a front cap is provided on the other end. A circuit device is added onto the inner side of the front cap described above. The invention has the stronger capability of attenuating environmental noise and the good effect of suppressing noise, because of its unique structure and the corresponding circuit device.
