Detailed description of the invention
Earphone cord between earphone cord node of divergence (referring to the position that left side and the wire of right side earplug separate) and headset plug is called earphone main line.
The two-way sound insulation interference preventer of a kind of Wearable, it is combined into by mouth mask 1 and earmuff 2, mouth mask 1 covers face and cheek, earmuff 2 covers the ear of the left and right sides, mouth mask 1 is positioned at below, nostril, only hide face, chin and cheek (position between face and both sides ear), mouth mask 1 and earmuff 2 are referred to as cover body, size, the shape of cover body are determined according to the facial characteristics of different crowd, comprise the general proportions of face, nose, chin and ear and position relationship and determine, being divided into large size, medium size, small size three kinds of models. Mouth mask 1 and earmuff 2 are referred to as cover body, and cover body is made up of shell 6, inner casing 8, vacuum cavity 7, polyurethane material 4 and EPE expanded polyethylene foam liner 3; Shell 6 and inner casing 8 are the plastic materials that have compared with obdurability and anti-pressure ability, can bear the pressure differential that external atmosphere pressure and vacuum lumen form, and occur under external force easily to return to previous status after elastic deformation. Between shell 6 and inner casing 8, be the vacuum cavity 7 that 1-8mm is thick, for sound insulation. The upper lower limb of mouth mask 1 and earmuff 2 port edges (are that mouth mask 1 and earmuff 2 are made as a whole outer ledge, be the outer ledge of cover body) adopt polyurethane material 4 to wrap up, polyurethane material is wear-resisting, sound insulation, flexible, with the comfortable nature of skin attachement, can reduce the unofficial biography of sound wave. It is a kind of prior art that mouth mask 1 edge under face is provided with elasticity line card 5(line card, and the utility model wraps up elastic on existing line card, makes its medial aperture can carry out elasticity expansion and contraction. ) line card 5 is made up of notched elastic annulus, breach, for the turnover of earphone main line, is convenient to directly earphone main line be sent in line card 5 holes from line card 5 outer ends; The diameter of line card 5 elastic annulus is greater than the diameter of earphone main line and is less than the minimum diameter of earphone cord node of divergence, ensure the node of divergence of different size earphone cord can frame can landing on line card 5.
