Arm 3d is to extend to form along the mode of a plane.Thus, wear at left ear in any position worn with position and auris dextra with position and be not worn on ear with can both there is no sense of discomfort.

In addition, arm 3d is formed by having flexible material.Thus, when with base portion 3a for stiff end time, following distortion can be realized, that is: make in the mode of the counter clockwise direction or clockwise direction movement that make leading section 3e lateral view 1 that degree of crook expands, the distortion reduced; And make the torsional deflection of fore-and-aft direction (paper both forward and reverse directions) movement of leading section 3e lateral view 1.

Microphone portion 4 has: microphone base portion 4a, and it is assembled in main part 1 rotationally within the scope of the predetermined angular around axis CLb; Bar portion 4b, it is worn with position from microphone base portion 4a diagonally forward extension to left down at left ear; And microphone main body portion 4c, it is arranged on the front end of bar portion 4b, and is accommodated with microphone unit MU.

Wire (not shown) extends from microphone unit MU, and this wire is by bar portion 4b and by line 5 together with the wire from loudspeaker unit SP.

The predetermined angular range set of microphone portion 4 when axis CLb rotates is, angle θ 4 identical in the lateral direction centered by axis CLa in the rearview of Fig. 1.This angle θ 4 under the state that headset 51 is worn on auricle E, the angle near the corners of the mouth being positioned at user as microphone main body portion 4c, and being set properly together with shape of bar portion 4b etc.Such as this angle θ 4 ≈ 45 °.

In FIG, represent that headset 51 is in the use location that auris dextra wears the microphone portion 4 when using position with double dot dash line.

The front of line 5 is as the plug be connected with external equipment (not shown).This plug is connected to external equipment, thus exports the output sound from external equipment from loudspeaker unit SP, and external device supplies the sound collected by microphone unit MU.

Headset 51 utilizes above-mentioned structure and hangs in the portion of rear side root unit of auricle E by hanger portion 3, thus ear pad portion 1a abuts with the local of the mode of closed external auditory meatus with auricle E naturally, utilize the small flexure of the ear-hanger 3 with hooking simultaneously, ear pad portion 1a is to auricle E active force, therefore, it is possible to the sense of stability had to a certain degree is worn.

Fig. 4 is the stereogram representing this wearing state.Under this wearing state, microphone main body portion 4c (not shown in Fig. 4) is positioned near the corners of the mouth of user, and collects the sound of user well.

Sidepiece HD, the auricle E of left side of head shown in Fig. 4 and the headset 51 be worn on auricle E.When headset 51 being worn on the auricle E of usual shape, axis CLa relative to the head above-below direction of upright user, in top slightly to the posture that front tilts.

In addition, headset 51 is to be worn on auricle E as follows, namely under wearing state, the edge 3b1 of the occiput side of the axle portion 3b arranged side by side in hanger portion 3 be in the edge E3a of the face side in crus helicis E3 near to or in contact with position, arm 3d is along the outer shape of the side, rear portion of root unit of auricle E simultaneously, and leading section 3e extends to face side with the degree exceeded corresponding to the position of ear-lobe E2.

Below, the extension stop 3f of main reference Fig. 5 and Fig. 6 to arm 3d is described.

Fig. 5 is the cutaway view on the S1-S1 position in Fig. 1.Conveniently represent inner side (main part 1 side) and the outside of the curved shape relative to arm 3d with arrow in Fig. 5.

Under the using state of headset 51, outside is the side becoming roughly top, and inner side is the side becoming roughly below.Fig. 6 is the cutaway view of extension stop 3f headset 51 being worn on the state of left ear.

Arm 3d has: the core 3d1 be bent to form as core; And the covering part 3d2 of the roughly whole side face of covering core 3d1, this arm 3d is such as formed by dual-color forming.

In arm 3d, core 3d1 buries underground than the line 5 Fig. 1 near front position from base portion 3a side.

That is, the position AR1 comprising the leading section 3e side at the position corresponding to line 5 does not bury core 3d1 underground and is only formed by covering part 3d2.Thus, position AR1 is more soft than the position being embedded with core 3d1.

Thus, make hanger portion 3 left ear wear to wear with position and auris dextra with position between rotate time, position AR1 moderate finite deformation can be made and stride across line 5.

Core 3d1 is formed by such as POM (polyacetals) resin.Covering part 3d2 is formed by such as thermoplastic elastomer (TPE), silicone rubber.

The fore-and-aft direction that makes in shape of cross section of arm 3d is the roughly oval of long limit.

Such as, long edge lengths Da=5.2mm, bond length Db=4.2mm.

As shown in Figure 5, hang stop 3f and have: extension 3f1, it extends to form from the side of the end, long limit of covering part 3d2 to oblique rear; And extension 3f2, it extends to form from the opposite side of end, long limit to oblique front.

In this example embodiment, extension 3f1 and extension 3f2 is formed in the position identical from the bending bearing of trend kink 3c to leading section 3e of arm 3d.

In addition, extension 3f1 and extension 3f2 is formed as thin tabular.

In Figure 5, formed by the line stretcher CLf2 of the line stretcher CLf1 becoming the bearing of trend of extension 3f1 and the bearing of trend that becomes extension 3f2, bad angle θ a be such as about 100 °, and fixes on the bending bearing of trend of arm 3d.

In addition, relative to the extended line LNa of the minor axis of arm 3d, line stretcher CLf1 and line stretcher CLf2 with the identical angle (half of bad angle θ a: θ a/2) tilts.This angle does not need consistent accurately, as long as the roughly equal angle that can be identified as the degree of roughly the same angle under visual is just enough.

Extended line LNa is set as the plane extended along arm 3d.

If extended height Lf1, Lf2 of each extension 3f1,3f2 to be set as the distance of intersection point P1, P2 of outline line from the front end of each extension 3f1,3f2 to arm 3d and line stretcher CLf1, CLf2, then in this example embodiment, the extended height Lf1 of extension 3f1 is equal with the extended height Lf2 of extension 3f2.

In addition, this extended height is such as Lf1 (=Lf2)=4.3mm.

Each extension 3f1,3f2, on the direction along arm 3d, are at least formed in the scope of extended distance Rb of the regulation shown in Fig. 1.And each extension 3f1,3f2, in the scope of extended distance Rb, are formed as such as presenting fixing extended height.

At this, extended distance is not most short lines distance and refers to the distance of the bending bearing of trend along arm 3d.

The range set of this extended distance Rb is the extended distance Ra separating regulation from the edge 3b1 of axle portion 3b arranged side by side.

This extended distance Rb is positioned at the scope on arm 3d, if each extension 3f1,3f2 at least partially extending in the scope of the length half of above-mentioned wrist 3d from the bond sites with hanger column sections 2.

According to this setting, due to the latter half remarkable softness compared with the first half of auricle E, therefore in the stability worn, preferably make extension stop 3f correspond to the first half of auricle E, then wear stable posture.

The bar portion 4b in microphone portion 4 extends longlyer and is formed as arm, and to be thus easily fulcrum with main part 1 vibrate to the paper orthogonal direction of Fig. 1 the microphone main body portion 4c of front end.Therefore, with main part 1 be viewpoint with the arm 3d of 4c opposition side, microphone main body portion on arrange and hang stop 3f, thus effectively can suppress the vibration of microphone main body portion 4c.

Each extension 3f1,3f2, as shown in Fig. 1 etc., have rake 3f1a, 3f2a in the scope of extended distance Ra1, and its extended height Lf1, Lf2 are along with the step-down gradually towards kink 3c.And, there is rake 3f1b, the 3f2b along with the step-down gradually towards leading section 3e in the scope of extended distance Rc1.

Extension 3f1 and extension 3f2 is integrally formed with soft covering part 3d2.Thus, extension 3f1 and extension 3f2 has flexibility respectively on the direction (arrow DRa direction) that line stretcher CLf1, CLf2 and extended line LNa angulation increase and decrease.

The distance LH of fore-and-aft direction by the mutual interval angles of setting and bad angle θ a and extended height Lf1, Lf2, thus is set as becoming more than predetermined distance LHa by extension 3f1 and extension 3f2.

This predetermined distance LHa is 12mm, and it is set to larger than the gap of the sidepiece HD of common human body head and the side, portion of root unit of auricle E.

That is, when being hooked on auricle E with the posture shown in Fig. 5 by arm 3d, extension 3f1 abuts with the surface of the head side of auricle E, and extension 3f2 abuts with the sidepiece HD of head.

Also be described with reference to Fig. 6.

Fig. 6 is the cutaway view corresponding to the part of hanging stop 3f when being worn on auricle E by the headset 51 possessing hanger portion 3, and wherein this hanger portion 3 has above-mentioned extension stop 3f.

Specifically, Fig. 6 is equivalent to the section on the S2-S2 position in Fig. 4, and is recited as and comprises the helix E1 of auricle E and the sidepiece HD of head.

When arm 3d is hung over auricle E is formed in using state time, hang the extension 3f1 of stop 3f abut with the surperficial E1a of the head side E1 of helix E1, extension 3f2 abuts with the sidepiece HD of head.

And because distance LH (with reference to Fig. 5) is wider than the clearance gap of the side, portion of root unit of helix E1 and sidepiece HD, therefore two extensions 3f1,3f2 bend (white arrow) in mode close to each other.

With this flexure, extension 3f1 is to making helix E1 from direction force (arrow F1) that sidepiece HD leaves, and extension 3f2 counter-lateral quadrents HD is headward medially to force (arrow F2).

Thus, between extension stop 3f and helix E1 and sidepiece HD, eliminate gap, and the wearing position of arm 3d is held stably.

Therefore, wearing stable posture and can obtaining better wearing sense of the headset 51 with the hanger portion 3 hanging stop 3f is possessed.

As long as hang stop 3f be arm 3d from the position corresponding to auricle E during wearing kink 3c to leading section 3e, then also can be arranged on optional position.

But near the crus helicis E3 being connected to sidepiece HD of the face side of helix E1, because helix E1 and sidepiece HD angulation are in acute angle more, the power therefore acted on as shown in arrow F1 and arrow F2 becomes large.Therefore, preferably avoid this neighbouring position and formed, with avoid produce user wear sense of discomfort.

That is, in arm 3d, preferably the position (non-extension stop: the position corresponding to extended distance Ra) that there is not extension 3f1,3f2 is set between kink 3c and extension stop 3f.

When not arranging kink 3c, preferably be linked to as arm 3d main part 1 side position the position becoming the portion of root unit of arm 3d and hang between stop 3f the position that there is not extension 3f1,3f2 be set.

Thus, extension 3f1,3f2 avoid comparatively hard with auricle E's and do not allow the position at yielding position to abut, and, it is exerted a force in the mode of the Directional Extension left from sidepiece HD to make this position, therefore, it is possible to reasonably wear, the possibility that user produces sense of discomfort extremely tails off.

Embodiment of the present utility model is not limited to above-mentioned structure, also can be variation as follows in the scope not departing from the utility model main points.

(variation 1)

Headset 51 also can remove microphone portion 4 and as supra-aural earphone 52 as shown in Figure 7.In other words, headset 51 is additional microphone portions 4 on supra-aural earphone 52.

The main part of supra-aural earphone 52 also can be so-called earplug pattern, duct pattern.

(variation 2)

Main part 1 and hanger portion 3 also can not carry out integration.Such as, possess that to hang the hanger portion 3 of stop 3f also can be following ear-hang hanger 54, its for be arranged on be not supra-aural earphone on and can use as supra-aural.

Fig. 8 (a) and Fig. 8 (b) is the ideograph for illustration of ear-hang hanger 54.

Having shown in Fig. 8 (a): the earphone EP of duct pattern, is not namely an example of the earphone of supra-aural; And the ear-hang hanger 54 of variation 2, this earphone EP is used as supra-aural.

Earphone EP has: main part 61; Earpiece 68, it inserts in external auditory meatus in use; And line 65, it is drawn from main part 61.

Ear-hang hanger 54 is bending parts the same with the hanger portion 3 of headset 51, and it has with arm 3d, kink 3c and hanger main part 543d, the kink 543c corresponding with hanging stop 3f and hangs stop 543f.Hanging stop 543f is the structure the same with the extension stop 3f illustrated in embodiment, and it has extension 543f1,543f2 of being equivalent to extension 3f1,3f2 on the lateral surface of the curved shape being arranged on hanger main part 543d.

In addition, hanger main part 543d is provided with groove 543j, line 65 can be inlaid on the inboard portion of curved shape by it.

The line 65 of earphone EP is embedded the groove 543j of ear-hang hanger 54, thus earphone EP can be used as the supra-aural such as shown in Fig. 8 (b).

(other variation)

The above embodiments and variation 1,2 are not limited to the ear-hang hanger that can be worn on the ear of left and right either side, also can be the ear-hang hangers that left ear is special or auris dextra is special.

When the ear of the either side becoming left side and right side is special, such as, the arm 3d in embodiment can not be made to become shape along a plane, in order to be more suitable for wearing the auricle E of side and the sidepiece HD shape of head, and become also bending to the paper orthogonal direction of Fig. 1 shape.

In addition, for extension stop 3f, may not be as described in Example relative to extended line LNa with the impartial angle in front and back to set line stretcher CLf1, CLf2.

Illustrate as the special situation of left ear for example, referring to Fig. 9 (a) and Fig. 9 (b).

Situation shown in Fig. 9 (a) with Fig. 6 is identical, is to observe the helix E1 of left ear and the cutaway view of sidepiece HD from occiput side, and Fig. 9 (b) uses and the shape of more suitable extension stop 3fA for illustration of wearing as left ear.

In Fig. 9 (a), the above-below direction under the erectility of user is represented as direction, the world with arrow.

As shown in Fig. 9 (a), the sidepiece HD of head becomes the face along roughly direction, the world.On the other hand, the surperficial E1a of the head side of helix E1 becomes the face along with roughly tilting relative to direction, the world towards side, sky in the mode left from sidepiece HD.

Thus, when also setting line stretcher CLf1, CLf2 of hanging stop 3f with impartial angular distribution in front and back relative to extended line LNa, then the distortion of the deformation ratio extension 3f1A of the extension 3f2A sometimes abutted with sidepiece HD is large.Now, the power that counter-lateral quadrents HD applies becomes large, likely becomes for the user and is difficult to naturally be worn sense.And on the other hand, the power that anthelix E1 applies becomes too small, according to pinna shape, sometimes may wish more stable to wear sense.

So, as shown in Fig. 9 (b), be more preferably the line stretcher CL2A of the extension 3f2A of sidepiece HD side and extended line LNa angulation θ b is set as less than the line stretcher CL1A of extension 3f1A and extended line LNa angulation θ a.

That is, be more preferably and make θ b< θ a.

Thus, the difference of the degree of flexibility of extension 3f1A when wearing and the degree of flexibility of extension 3f2A diminishes.That is, the difference of the active force of counter-lateral quadrents HD and the active force of anthelix E1 diminishes.Therefore, naturally sense can be worn for the user.

And the power that anthelix E1 applies can not become too small, can obtain by the impact of pinna shape hardly more stable wearing sense.

Shape, the mutual position relationship of hanging extension 3f1,3f2 of stop 3f can carry out various distortion.These examples shown in Figure 10 (b) to Figure 10 (d).

It is identical that extension 3f1,3f2 of illustrating in embodiment shown in Figure 10 (a) are set to development length on mutually corresponding position.

Figure 10 (a) to Figure 10 (c) observes from hanging (foreign side Fig. 5) directly over stop the figure hanging stop 3f.And Figure 10 (d) observes from side (rear Fig. 5) figure hanging stop 3f.

As shown in Figure 10 (b), extension 3f1,3f2 also can be disposed alternately on mutually not corresponding position.

In this example embodiment, the divided isolation of extension 3f1 is formed as extension 3f1a and extension 3f1b, is being formed with extension 3f2 corresponding on the position between them.

Extension 3f1,3f2 are divided into multiple, thus can not concentration of local and easily disperseing, therefore, it is possible to more naturally obtain wearing sense for the power effect of helix E1 and sidepiece HD.

Interval between extension 3f1 and extension 3f2 also can not be fixed.Such as, as shown in Figure 10 (c), also can be formed as kink 3c side is narrowed and leading section 3e side is broadened.The clearance gap of sidepiece HD and helix E1 is the shape of common auricle E along with broadening towards occiput side.Thus, because this example is when being worn on the gap of sidepiece HD and helix E1, with both to be close to degree higher, therefore suit the requirements.

Development length Lf1, Lf2 of extension 3f1,3f2 also can not fix.Such as, as shown in Figure 10 (d).

Also can be formed as making leading section 3e side than kink 3c side long (height).

The crus helicis E3 side being in face side of helix E1 is not easy distortion, to leave and along with becoming soft towards occiput side and being easily out of shape from crus helicis E3.

Thus, if the helix E1 of crura of antihelix E3 side excessively exerts a force, then user sometimes may feel active force and feel sense of discomfort to wearing.This variation large in the effect that it is possible to strengthen occiput side is preferred because of this point.

According to same idea, the thickness of extension 3f1,3f2 also can be made not fix, but make leading section 3e side thicker than kink 3c side.Thus, the active force of crus helicis E3 side is suppressed, therefore, it is possible to be more difficult to feel the sense of discomfort in wearing, thus preferably.

The above embodiments and each variation can independent assortments mutually within the bounds of possibility.
