Embodiment

Present embodiment is the utility model preferred implementation, and other all its principle is identical with present embodiment or approximate with basic structure, all within the utility model protection range.

Please referring to accompanying drawing 1 to accompanying drawing 7, mainly comprise sound guide tube 1, loudspeaker 2 and earphone body 3 in the utility model, wherein sound guide tube 1 cooperatively interacts with earphone body 3 and is installed together, and forms earphone, and loudspeaker 2 are arranged in the sound guide tube 1.In the utility model, on earphone body 3 rear end caps, offer air-vent 9, when loudspeaker 2 were done the piston type motion in airtight space, the gas that flows of generation can be inhaled action through air-vent 9 rows of being, the resistance that the air that receives when reducing the loudspeaker motion produces.In the utility model, air-vent 9 can be provided with one or more, and concrete quantity can be provided with according to actual needs; In the present embodiment, around air-vent 9, be provided with air drain 10, air drain 10 also can offer one or more; The shape of air drain 10 can be various geometries; Be preferably circle, in an air drain 10, can offer an air-vent 9, also can offer a plurality of air-vents 9.In the present embodiment, offer nameplate groove 11, in nameplate groove 11, be provided with a nameplate that matches with it 7, make air-vent 9 form concealed air-vent in air drain 10 outsides.

With three kinds of concrete execution modes the form of the air-vent 9 of the utility model is done below and is specified:

Embodiment one: please referring to accompanying drawing 8, in the present embodiment, on earphone body 3 rear end caps, offering a diameter is 6.5mm; The degree of depth is the nameplate groove 11 of 0.5mm, and offering a diameter in the nameplate groove 11 is the air drain 10 of 0.5mm for the 3mm degree of depth, the through hole that to offer a diameter in the air drain 10 be 1.0mm; Be air-vent 9; In the present embodiment, in nameplate groove 11, be provided with a nameplate that matches with it 7, make air-vent 9 form concealed air-vent.
