Description
Technical field
The utility model is relevant a kind of earphone rotary shaft structure, and espespecially one is provided with adjustment earmuff angle function, and is easy to receive the earphone rotary shaft structure design that folding carries, and is specially adapted to headphone or similar structures.
Background technology
Namely earphone has become the most basic auxiliary implement of music appreciating since invention, also be developed so far along with popular the electronic product more becoming a kind of fashion agitation, no matter structure function or appearance and modeling kind is real to be unequal to lifting more, especially the application of computer media in recent years and the generation of better acousto-optic audio-visual devices, Related product is more driven constantly to weed out the old and bring forth the new, wherein except providing the convenient and practical structure of more human nature to meet except the psychology of consumer's seeking change and innovation, the more important thing is that how guaranteeing that self product is leading guarantees that market competition is established oneself in an unassailable position, it is the problem that industry falls over each other to research and develop.
If and earphone is according to the differentiation of volume and structure, be broadly divided into ear type, duct-type, the kind such as supra-aural and wear-type, with regard to headphone, because its sounding monomer is large compared to other earphones, therefore it is also comparatively excellent in presenting of tonequality, then utilize grip force to be fixed on head two to pick up the ears face when it is worn, so have preferably fixed form than other style earphone, but because everyone capitiform and ear shape are all not quite similar, though current headphone is on the market innovated all to some extent in function and shape-designing, but be difficult to meet the people of different capitiform and ear size because of size difference, wear timing for a long time and still easily produce sense of discomfort.
Moreover, user is allowed more easily to obtain presenting of former sound though headphone has excellent tonequality, but relatively also because its volume easily takes up room comparatively greatly, therefore cause storage and carry very inconvenient, originally mostly be and used in indoor, but recently with the progress of person's science and technology and the change of fashion trend, headphone also gradually moves towards outdoor along with the prevailing of intelligent mobile phone, street corner is found everywhere its user.Therefore, in order to promote collection convenience and product surcharge, many dealers more constantly innovate for headphone container structure, as a headphone being provided with the function that folds common on the market, it is mainly provided with a pivot structure in both sides upper arm in a place connecting earmuff, and this pivot structure is provided with holding firmware, earmuff can be connected in earphone both sides for, and when rotating shaft bending makes holding firmware mutually depart from, then can by both sides earmuff to adduction folding, make the aspect of the rectangular shape of earphone containing, be easy to carry with further reduced volume.But due to this pivot structure only tool receive use effect of folding, design still has weak point.
A kind ofly more meet user in the difference of congenital people because of size and the headset structure of portability therefore how to design, for consuming public, for the utility model motivation for grinding wound.
Summary of the invention
