Description

Headphone structure

Affiliated technical field

The utility model relates to a kind of Headphone structure, relates in particular to a kind of earphone card padlock fixed structure.

Background technology

Along with electronic products such as mobile phone, MP3, computer development and application widely with rapid changepl. never-ending changes and improvements, the consumer, just has higher requirement to the tonequality and the audibility that are provided to earphone on the electronic products such as mobile phone, MP3, computer as the consumer also in continuous raising to the requirement of its appurtenances.

Existing earphone has plastic shell, loudspeaker monomer and moulds shell, and the loudspeaker monomer has a bronze medal dish.When assembling has earphone now, need on the copper dish of loudspeaker monomer, to coat earlier to be stained with glue, then with the direct gluing of copper dish in moulding shell, coat to be stained with glue and the plastic shell cemented at the plastic shell more at last and mould on the shell, but mould shell and earphone, plastic shell and mould shell be stained with fashionable, usually be stained with the glue amount and be not easy control, thereby can cause too much being stained with on the vibrating reed of solation to the loudspeaker monomer, therefore cause earphone distortion and fraction defective height.With regard to ordinary circumstance, its distortion rate can be below 10% when sending the audio frequency of 100Hz for the loudspeaker monomer, and after the assembling mode assembling of adopting above-mentioned existing earphone, distortion rate then can rise to more than 15% during the audio frequency of earphone transmission 100Hz.

The utility model content

Main purpose of the present utility model is to provide a kind of Headphone structure at the defective that above-mentioned prior art exists, and this Headphone structure can not only make assembling back earphone air-tightness good, and can reduce the distortion of earphone, the yield of raising earphone assembling.

For achieving the above object, the utility model Headphone structure comprises housing, lid and loudspeaker monomer.Housing has a wire connecting portion, and wire connecting portion one end extends to form cover body portion, and the opening part of cover body portion is the cover body edge of a circle, is provided with a plurality of fixture blocks on the cover body edge uniformly, offers draw-in groove on the cover body edge of each fixture block left and right sides.Lid have in the form of a ring with the corresponding lid wall in cover body edge, be provided with the groove that the corresponding fixture block of a plurality of confessions embeds in the inboard of lid wall, the lid wall respectively convexes with a projection that embeds in the housing draw-in groove at each place, groove both sides.The loudspeaker monomer places in the lid and fastens on the projection of lid wall.

As mentioned above, the utility model Headphone structure fastens on the loudspeaker base by the projection that is provided with on the lid wall inboard of cover body part, therefore cover body part can fix mutually closely with the loudspeaker monomer and be in the same place, simultaneously the projection on the lid wall matches with draw-in groove on the cover body edge again, thereby lid and cover body are combined closely, therefore the utility model Headphone structure can not need be stained with glue and just the loudspeaker monomer can be retained on lid, thereby the earphone air-tightness after the assembling is good, audio distortion is little, assemble the yield height.

Embodiment

By describing technology contents of the present utility model, structural feature in detail, being reached purpose and effect, enumerate below that embodiment and conjunction with figs. are detailed gives explanation.

See also Fig. 1 and Fig. 2, the utility model Headphone structure mainly comprises a housing 10, one lids 20 and is contained in loudspeaker monomer 30 in the accommodation space that housing 10 and lid 20 be buckled into.

See also Fig. 2 and Fig. 3, housing 10 has the shaft-like wire connecting portion 11 that is that is connected with outside wire rod.Wire connecting portion 11 1 ends extend to form the cover body portion 12 of circular open shape.The opening part of cover body portion 12 forms cover body edge 121, and cover body edge 121 is provided with three fixture blocks 122.Three fixture blocks 122 are evenly distributed on the cover body edge 121, and each fixture block 122 roughly is strip and fixture block 122 outwards vertically extends cover body edge 121.Cover body edge 121 all offers one to be run through 121 outsides, cover body edge and inboard roughly is trapezoidal draw-in groove 123 in each fixture block 122 left and right sides, this draw-in groove 123 near the A/F of 121 outsides, cover body edge greater than A/Fs near 121 inboard places, cover body edge.

See also Fig. 2 and Fig. 4, lid 20 have in the form of a ring with cover body edge 121 corresponding lid walls 21.Be provided with three grooves 211 in lid wall 21 inboards, these three grooves 211 are evenly distributed in the inboard of lid wall 21.Lid wall 21 respectively convexes with a projection 212 that is the triangle column at place, each groove 211 both sides.The one side of projection 212 towards lid 20 outsides is the inclined-plane, and projection 212 is vertical with the lid wall 21 of lid 20 towards the one side of lid 20 inside.

See also Fig. 2 and Fig. 5, loudspeaker monomer 30 has a cylindrical loudspeaker base 31 and and is convexly set in cylindrical and its diameter on the loudspeaker base 31 less than the horn main body 32 of loudspeaker base 31 diameters, thereby loudspeaker base 31 upper edge are shunk to loudspeaker base 31 and horn main body 32 junctions and formed a base top surface 311.When loudspeaker monomer 30 matches with lid 20, because the one side towards lid 20 outsides of the projection 212 of lid wall 21 is the inclined-plane, so when loudspeaker monomer 30 is arranged in the lid 20, loudspeaker monomer 30 can slip into along the inclined-plane of projection 212 in the lid 20, and then fasten at projection 212 on the one side of lid 20 inside, because projection 212 is vertical with lid wall 21 towards the one side of lid 20 inside, thereby projection 212 closely fastens with the base top surface 311 of loudspeaker base 31, and lid 20 and loudspeaker monomer 30 are combined closely.

When housing 10 engaged mutually with lid 20, cover body edge 12 inserted the inboard of lid wall 21 and closely contacts with lid wall 21, and the fixture block 122 on the cover body edge 12 snaps in lid wall 21 inboard going up in the corresponding groove 211.When matching with the cover body edge 121 of cover body portion 12, this projection 212 slips in the draw-in groove 123 of cover body portion 12, thereby projection 212 is held in the draw-in groove 123 at cover body edge 121 closely, thereby lid 20 being combined with housing 10 form an accommodation space is contained in loudspeaker monomer 30 wherein.

From the above mentioned, the utility model Headphone structure cooperates by holding mutually between the base top surface 311 on the loudspeaker base 31 of the projection 212 of the triangle column that is provided with on the lid wall 21 of lid 20 and loudspeaker monomer 30, and loudspeaker monomer 30 is contained in the accommodation space that housing 10 and lid 20 form, thereby the earphone air-tightness after the assembling is good, and need not be stained with glue, therefore adopt the earpiece audio distortion of the utility model Headphone structure little, assemble the yield height.

Below only be an embodiment of the present utility model, from not limiting scope of authority of the present utility model with this.Therefore have common skill person in the technical field under all and do equivalent variation, all be covered by in the claim of the present utility model according to spirit of the present utility model.
