A communication earpiece without impulse and high frequency noise, includes an earpiece housing having a chamber and a loudspeaker mounted in the chamber of the earpiece housing, wherein a plurality of sound outlet meshes is provided on a front surface of the earpiece housing. A resonant piece is mounted and encircled around the loudspeaker, wherein two or more peripheral sides of the resonant piece are affixed on an inner surface of the earpiece housing in such a manner that provides at least a passage gap between the inner surface of the earpiece housing and the resonant piece so as to prevent the impulse noise directly impact to the human ear. Besides, the sound, which is reproduced by the interference with two different phases of wave, will reduce the high frequency noise that become more pure and clarity. |
