发明名称 COMMUNICATION EARPIECE WITHOUT IMPULSE AND HIGH FREQUENCY NOISE
摘要 <p>The present invention is to provide a communication earpiece without impulse and high frequency noise, wherein the earpiece consists of an earpiece housing (10) having a chamber inside thereof and a loudspeaker (20) mounted therein, wherein a plurality of sound outlet meshes (11) is mounted on the surface of the earpiece housing (10) hanging on the human ear (A); a resonant piece (21) is mounted and encircled the loudspeaker (20), and therein two or more proper sides of the resonant piece affixing on the inner surface of the earpiece housing (10); the lower impulse noise output end (22) according to two output ends of the loudspeaker (20) facing to the sound outlet meshes of the earpiece housing in order to prevent the impulse noise directly impact to the human ear; and 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.</p>
