| titleOfInvention | Multi-unit bone conduction earphone and bone conduction listening device |
| abstract | The utility model belongs to the technical field of the earphone, especially, relate to a polycell bone conduction earphone, including the earlap that is used for laminating skin and with the ear lid that the earlap is connected, its characterized in that, the earlap has the binding face that is used for laminating with skin, the earlap with form accommodation space between the ear lid, accommodation space is divided into near sound district and at least one distant sound district along the direction that is on a parallel with the binding face of earlap, each the distant sound district sets gradually towards the direction of keeping away from the near sound district, be equipped with the bone conduction unit that is used for producing different frequencies respectively in near sound district and each the distant sound district; the bone conduction unit is arranged in the near sound zone and the far sound zone to improve the sound transmission effect of the bone conduction earphone, the bone conduction unit generating high frequency is arranged in the near sound zone to improve the high frequency transmission effect, and the bone conduction unit generating medium and low frequency is arranged in the far sound zone, so that the multi-channel stereo effect is achieved, and the tone quality effect of the bone conduction earphone is improved. |
