An on-ear type noise canceling earphone comprises: a protective cover body; a loudspeaker element; and a sound capturing microphone element. A first protrusion portion and a second protrusion portion are formed on a first surface of the protective cover body, and a third protrusion portion is formed on a second surface. The first protrusion portion and the third protrusion portion form a first accommodation space, and the second protrusion portion forms a second accommodation space. The loudspeaker element is installed in the first accommodation space, and the sound capturing microphone element is installed in the second accommodation space. The loudspeaker element includes a circuit element and a loudspeaker unit, and an RCA cable is combined and connected to the loudspeaker unit and the sound capturing microphone element by the circuit element. The sound capturing microphone element is installed at a position approaching an ear canal, and a low-frequency response is enhanced in the accommodation space to improve sound analysis. And noise is effectively decreased outdoors or while walking. |
