Therefore, the external diameter of the wire rod 6 in the hook portion 2 is less than the external diameter of wire 5, and this wire rod 6 is configured in the center of curvature one side of relative wire 6, it is the upper covering section 7 of inboard and covering of hook portion 2, covering section 7 forms roughly uniform resin portion 8 of thickness relatively, thereby makes the cross sectional shape of hook portion 2 be the reverse drops that falls.Thus, be being worn between outer auricle ER and the head H D that the reverse drop-shaped hook portion 2 that falls can be very good.
That is, hook portion 2 and used that the earphone 50 of hook portion 2 is worn on ear feel very comfortable.
In addition, can guarantee the long-term reliability of wire 5.
Simultaneously, wire 5 is arranged on the shape outside along the root bending of outer auricle ER, so curvature is less, and namely radius of curvature is larger.Therefore, follow the crooked stress that produces further to diminish on the wire 5.
In addition, because covering section 7 is fixing, the relative position of wire 5 and wire rod 6 can be maintained, and can not produce dislocation.That is, even hook portion 2 produces distortion, the position of wire 5 also can maintain the outside.Therefore, though in long-term use procedure repeated deformation, the stress that produces also can often maintain a lower level.
So because the various stress that apply are smaller on the wire 5, so wire 5 that the possibility of the faults such as the bad and broken string of conduction occurs is extremely low, long-term reliability will be protected.
In addition, can not break down easily even bear unusual huge external force yet.
The equal coating cap 7 in the two ends of wire rod 6 covers, and fits tightly with wire 5 owing to the effect of covering section 7 simultaneously.Covering section 7 is heat-shrinkable T bush, and the described state that fits tightly is to be maintained by the fastening force of following thermal contraction to produce.
Therefore, in the normal operation state range, even hook portion 2 deforms, wire rod 6 with respect to wire 5 radially, circumferential and vertically also can not be offset because of the distortion of hook portion 2.
In addition, because wire 5 and wire rod 6 coating caps 7 and resin portion 8 cover, therefore, even if owing to wrong occupation mode of non-subjectivity etc. makes hook portion 2 and earphone 50 suffer unusual huge external force, such as the deformation force that can cause damaging etc., wire rod 6 occurs, and to expose the possibility of the faults such as outside also extremely low.
Need not superfluous words, embodiment of the present utility model is not limited in above-mentioned structure and step.So long as in the scope that does not break away from the utility model purport, even if variation is effective too.
Ear-hanger HG is not only applicable to earphone.For example, it is also applicable to the so-called built-in earphone and the hearing aids that contain microphone.
The material of wire rod 6 not only is limited to SUS, also can adopt other metal material or resin material.More particularly, marmem and the shape memory resin that can remember the regulation shape all can.
That is, wearing in the state of earphone 50, and do not mean that wire rod 6 one fixes on respect to wire 5 vertical.When the center of curvature because curve form and not on vertical plane the time, wire rod 6 will be arranged on and contain the center of curvature in interior plane.
More than as an example of earphone 50 example the embodiment that is applicable to auris dextra is illustrated, only have one-sided equipment with earphone but be not limited in, also applicable to containing a pair of main part HT that a pair of left and right sides ear uses, the stereo kind equipment that can be used to listen stereo sound.
