The present invention relates to an earpiece impulse and high frequency noise which consists of an earpiece housing (10) and a loudspeaker (20) mounted therein, wherein a plurality of sound outlet meshes (11) is mounted on one surface of the earpiece housing; a resonant piece (21) encircling the loudspeaker (20), and therein a proper side of the resonant piece (21) affixing on the inner surface of the earpiece housing; the lower impulse noise output end according to two output ends of the loudspeaker facing to the sound outlet meshes of the earpiece housing; when the earpiece is used to listen music or hear voice, it can not only prevent impulse noise directly impact to the human ear but also provide a high clarity sound interval produced by the interference of the high and low intensive sound wave.

L'invention concerne un écouteur se composant d'un boîtier, d'une enceinte (20) acoustique logée dans le boîtier (10) à partir de laquelle une pluralité de réseaux de sorties de son (11) sont montés sur une surface du boîtier, d'une pièce de résonance (21) encerclant l'enceinte acoustique (20) et un côté adapté de cette pièce de résonance (21) fixant la surface intérieure du boîtier, d'une extrémité de sortie de bruit à impulsion inférieure selon les deux extrémités de sortie de l'enceinte acoustique faisant face aux réseaux de sortie de son du boîtier. Si l'on écoute de la musique ou une voix avec ces écouteurs, non seulement les bruits d'impulsion n'affectent plus l'oreille humaine mais l'intervalle sonore produit par l'interférence de l'onde intense haute et basse est plus clair.
