Supra-aural earphone

Technical field

The present invention relates to supra-aural earphone, in more detail, relate to freely to change the technology of supra-aural earphone of the bearing position of the ear-hang body that tangles along the root portion of auricular concha.

Background technology

Headphone in the past generally has pair of shells, and this housing has and the corresponding headphone assembly in left duct and right duct, forms by each housing being installed on the two ends that are the headband of U font roughly.

In addition, above-mentioned headphone, except the earphone of the pattern that as opening and hermetic type, whole auricular concha covered, the external auditory meatus side of inserting auricular concha is also arranged and with tragus with to the headphone of the so-called earplug pattern of pearl maintenance housing etc. with housing.

But there are individual differences in shape and the size of wearing the auricular concha side of housing, and therefore, particularly for the housing of ear inserting type, the sense of wearing during use also has the tendency that varies with each individual.That is, under the little people's of auricular concha situation, the auricular concha side is inserted into the housing compressing of external auditory meatus side and algesiogenic sensation or form the compressing impression sometimes.On the other hand, under the big people's of auricular concha situation, a little less than the confining force of auricular concha side for the housing that is inserted into the external auditory meatus side,, also can come off sometimes even be collided a little.

Therefore, the portability of the headphone that has both ear inserting type and the headphone of the divergence type of the property the worn advantage of the headphone of style of opening are also provided recently.The headphone of this pattern has such structure, that is, each housing in left duct and right duct separated and make it independent, the ear-hang body is installed on each housing, the ear-hang body can tangle (being referred to as in this manual, " supra-aural earphone ") along the root of auricular concha.

But the above-mentioned supra-aural earphone of divergence type all the time is that the ear-hang body is installed on the housing integratedly, utilizes the elasticity of torsion of giving the ear-hang body, and housing is installed to the auricular concha direction pushing application of force.

Therefore, with the same in the past, making under the different situation of the pushing force of giving housing because of showing that individual differences on the auricular concha size, particularly angular aperture are different, exist such problem, that is, because for the difference of the power that is adjacent to of auricular concha side, according to people's situation, the algesiogenic sensation of meeting perhaps easily splits away off from ear.

So, the supra-aural headphone (supra-aural earphone) of the applicant has proposed the to have patent documentation 1 wearing position governor motion shown in (Japanese patent application bulletin No.2000-34089: the spy opens the 2002-34089 communique).This supra-aural earphone has: along the ear-hang body of the root bending of auricular concha; Be installed in the distolateral axial region going up and be configured in the auricular concha front side of ear-hang body; Can be bearing on the axial region rotatably and have the housing of electroacoustic transition components via bearing portion.According to this earphone, the ear-hang body is tangled and when supporting, the axial region on supporting shell side is configured in the front side of tragus along the root of auricular concha, therefore, not only the auricular concha side can not be oppressed, and can make housing and auricular concha side-to-side anastomosis simply.

But according to the prior art that above-mentioned patent documentation 1 is disclosed, component parts quantity is many, so the problem that exists its assembling procedure also to become miscellaneous.In addition, the ear-hang body is also fixed to the position that tangles of the root side of auricular concha, therefore, also exists and can not change the not free of its position as required afterwards.
