在这一例子中，扬声器单元12具有安装在其外周面上的由弹性材料构成的包装件15，并且通过该包装件15收纳在第2盖27的内部空间28内。装饰部件42具有形成圆盘状的盖板43。在盖板43的里面侧，设置被强制嵌合在第2盖27的卡止孔29内的固定件44。In this example,speaker unit 12 haspackage 15 made of an elastic material attached to its outer peripheral surface, and is housed ininternal space 28 ofsecond cover 27 throughpackage 15 . Thedecorative member 42 has acover plate 43 formed in a disk shape. On the back side of thecover plate 43, afixing member 44 forcibly fitted into thelocking hole 29 of thesecond cover 27 is provided.

耳廓用支撑部件32由可以自如地弹性变形的弹性体橡胶和硅酮橡胶等弹性材料形成，具有可自由拆装地安装在第2盖27上的安装基部33和从该安装基部33的一部分向侧边突出设置的耳廓卡止部38。Theauricle support member 32 is formed of elastic materials such as elastically deformable elastomer rubber and silicone rubber, and has amounting base 33 detachably mounted on thesecond cover 27 and a part of themounting base 33. Theauricle locking part 38 protrudes to the side.

安装基部33为圆筒状，具有在其前端面侧开口的收纳空间34，在该收纳空间34内收纳第2罩27。而且，在安装套筒33的后端面35上，形成用于将盖板43的固定件44引导到第2罩27的卡止孔29中的贯通孔36。Theattachment base 33 has a cylindrical shape, has astorage space 34 opened on the front end side thereof, and accommodates thesecond cover 27 in thestorage space 34 . Further, athrough hole 36 for guiding thefixing member 44 of thecover plate 43 to thelocking hole 29 of thesecond cover 27 is formed on therear end surface 35 of theattachment sleeve 33 .

通过将第2罩27嵌入上述收纳空间34，安装基部33被安装到外罩22上，但作为其固定方法，可以使收纳空间34的内径比第2罩27的外径稍小，将第2罩27强制嵌合到上述收纳空间34内，也可以将第2罩27嵌入该收纳空间34后，利用盖板43的固定件44将安装基部33固定在外罩22上。By inserting thesecond cover 27 into the above-mentionedstorage space 34, theinstallation base 33 is installed on theouter cover 22, but as the fixing method, the inner diameter of thestorage space 34 can be made slightly smaller than the outer diameter of thesecond cover 27, and thesecond cover 27 is forcibly fitted into the above-mentionedstorage space 34, and after thesecond cover 27 is inserted into thestorage space 34, theinstallation base 33 is fixed on theouter cover 22 by thefixing member 44 of thecover plate 43.

耳廓卡止部38优选地形成为通过顶端部38a连结而成的环状，该顶端部38a是使从安装基部33的圆筒状外周面37的相对的两个位置大致沿着其切线方向引出的各臂的端部之间以规定的曲率弯曲而成的。Theauricle locking portion 38 is preferably formed in an annular shape connected by atop end portion 38a drawn from two opposing positions on the cylindrical outerperipheral surface 37 of theattachment base portion 33 approximately along the tangential direction thereof. It is formed by bending the ends of each arm with a prescribed curvature.

通过在将扬声器单元12收纳在由第1罩23和第2罩27构成的外罩22内，将耳廓用支撑部件32安装在外罩22的第2罩27侧之后，将装饰部件42即盖板43的固定件44强制嵌合在第2罩27的卡止孔29内，完成该内置耳机11的组装。By accommodating thespeaker unit 12 in theouter cover 22 composed of thefirst cover 23 and thesecond cover 27, and installing thesupport member 32 for the auricle on thesecond cover 27 side of theouter cover 22, thedecorative member 42, that is, thecover plate 43 is forcibly fitted into thelocking hole 29 of thesecond cover 27, and the assembly of the built-inearphone 11 is completed.

图2表示从如上组装的内置耳机11的装饰部件42侧观察的侧视图，图3表示其外观立体图。如图2所示，在耳廓用支撑部件32的安装基部33上设置软线保持部17，连接软线18从该软线保持部17引出。FIG. 2 shows a side view of the built-inearphone 11 assembled as above, viewed from thedecorative member 42 side, and FIG. 3 shows a perspective view of its appearance. As shown in FIG. 2 , acord holder 17 is provided on theattachment base 33 of theauricle support member 32 , and theconnection cord 18 is drawn out from thecord holder 17 .

而且，如图3所示，和之前图11说明的现有技术的例子相同，在设置在第1罩23中的耳塞24上，安装具有由柔软的橡胶弹性体构成的套管53的塞盖52。Moreover, as shown in FIG. 3 , as in the prior art example described in FIG. 11 , a plug cap having asleeve 53 made of a soft rubber elastic body is attached to theearplug 24 provided in thefirst cover 23 . 52.

在图4(a)、(b)中，分别表示将内置耳机11戴在耳廓61中之前的状态，和戴上之后的状态，在示出整个耳廓61的图4(a)中，61a是耳轮，62是耳屏，63是对耳屏，64是屏间裂隙，65是耳甲，66是位于耳轮61a内侧的对耳轮，67是位于耳甲65和对耳轮66之间的沟部。In Fig. 4 (a), (b), respectively show the state before the built-inearphone 11 is worn in thepinna 61, and the state after putting it on, in Fig. 4 (a) showing thewhole pinna 61, 61a is the helix, 62 is the tragus, 63 is the antitragus, 64 is the gap between the screens, 65 is the concha, 66 is the antihelix inside thehelix 61a, 67 is the groove between theconcha 65 and theantihelix 66 department.

这里，对软线保持部17和耳廓卡止部38的位置关系进行说明。在沿着耳廓61的屏间裂隙64配置软线保持部17时，耳廓卡止部38被配置在对耳屏63的附近，其顶端部38a进入耳甲65和对耳轮66之间的沟部67，与对耳轮66的内面弹性接触，从而确定了软线保持部17和耳廓卡止部38的位置关系。Here, the positional relationship between thecord holding portion 17 and theauricle locking portion 38 will be described. When thecord holding part 17 is arranged along the interscreen slit 64 of theauricle 61, theauricle locking part 38 is arranged near the antitragus 63, and itstip part 38a enters between theconcha 65 and theantihelix 66. Thegroove portion 67 is in elastic contact with the inner surface of the anti-helix 66 , thereby determining the positional relationship between thecord holding portion 17 and thepinna locking portion 38 .

如图5(a)-(c)所示，因为耳廓用支撑部件32相对于内置耳机11的外罩22可以拆装，所以能够将耳廓卡止部38的环形尺寸分别准备成适配例如大·中·小的耳廓用支撑部件32a～32c的尺寸，如图6所示，可以根据需要相对于外罩22而将耳廓用支撑部件32换为其它尺寸。As shown in Fig. 5 (a)-(c), because thesupport member 32 for pinna can be disassembled with respect to theouter cover 22 of built-inearphone 11, so can respectively prepare the annular dimension ofpinna locking part 38 to fit for example The sizes of the large, medium, and smallauricle support members 32 a to 32 c are as shown in FIG. 6 , and theauricle support members 32 can be replaced with other sizes with respect to theouter cover 22 as needed.

这样，如图7所示，在外罩22上可更换耳廓用支撑部件32a～32c的场合，通过在软线保持部17中沿着其长度方向放入缝隙17a，随着对耳廓用支撑部件32的替换，如图8所示，能够将从扬声器单元12引出的连接软线18配置在软线保持部17内。In this way, as shown in FIG. 7, when thesupport members 32a to 32c for the auricle can be replaced on theouter cover 22, by inserting theslit 17a in thecord holding part 17 along its longitudinal direction, the auricle is supported along with the auricle. In order to replace themember 32, as shown in FIG.

图9是表示耳廓用支撑部件32的另一变形例的说明图形，图9(a)表示侧视图，图9(b)表示正面图。因为该变形例将内置耳机用作为具有麦克风的头载耳机，所以耳廓用支撑部件32的安装基部33延设有臂39，在该臂39的末端支撑有麦克风40。Fig. 9 is an explanatory diagram showing another modified example of theauricle support member 32, Fig. 9(a) is a side view, and Fig. 9(b) is a front view. Since this modification uses the built-in earphone as a headphone with a microphone, anarm 39 is extended from the mountingbase 33 of thesupport member 32 for the auricle, and themicrophone 40 is supported at the end of thearm 39 .

因此，如图10所示，根据该变形例，基于耳廓用支撑部件32的耳廓卡止部38和耳甲65一侧和对耳轮66一侧之间的沟部67处于弹性接触的状态，故能够作为既可防止脱落，又可让使用者59的唇部60对着麦克风40的带麦克耳机(头载耳机)使用。Therefore, as shown in FIG. 10 , according to this modification, theauricle locking portion 38 of theauricle support member 32 is in elastic contact with thegroove portion 67 between theconcha 65 side and the anti-helix 66 side. , so it can be used as a headset with a microphone (earphone on the head) that can prevent falling off and allow thelip 60 of theuser 59 to face themicrophone 40.

本发明的内置耳机11通过将内装扬声器单元12的外罩22的耳塞24插入耳廓61的外耳道内的方式而使用。此时，如图4所示，优选沿着耳廓61的屏间裂隙64设置连接软线18的软线保持部17，使外罩22保持在耳屏62和对耳屏63之间。The built-inearphone 11 of the present invention is used by inserting theearplug 24 of thehousing 22 incorporating thespeaker unit 12 into the external auditory canal of theauricle 61 . At this time, as shown in FIG. 4 , it is preferable to provide thecord holder 17 for connecting thecord 18 along theintertruncal fissure 64 of theauricle 61 so that thecover 22 is held between the tragus 62 and the antitragus 63 .

这样，因为耳廓用支撑部件32的耳廓卡止部38配置在对耳屏63的附近，耳廓卡止部38的顶端部38a与位于耳甲65和对耳轮66之间的沟部67弹性接触，所以能够确保将外罩22固定在耳廓61中。因此，利用力的加减，即使偶然的拉力被施加到连接软线18上，也能够阻止内置耳机11的脱落。In this way, since theauricle locking portion 38 of theauricle support member 32 is disposed near the antitragus 63, thetop end portion 38a of theauricle locking portion 38 is in contact with thegroove portion 67 between theconcha 65 and theantihelix 66. The elastic contact ensures that theouter cover 22 is fixed in theauricle 61 . Therefore, even if an accidental pulling force is applied to theconnection cord 18 by the addition and subtraction of force, it is possible to prevent the built-inearphone 11 from coming off.

另外，因为耳廓卡止部38能够自由地弹性变形，所以即使耳廓61的形状因人而异，也能够抵消这一差别，始终使顶端部38a和沟部67接触。而且，因为耳廓用支撑部件32可以从外罩22取出，所以如图5所示，通过准备例如3个耳廓用支撑部件32a～32c适配不同环尺寸的耳廓卡止部38，能够适当地选择其形状最适合使用者的耳廓形状的耳廓用支撑部件32。In addition, since theauricle locking portion 38 can be elastically deformed freely, even if the shape of theauricle 61 differs from person to person, the difference can be canceled out, and thetip portion 38 a is always in contact with thegroove portion 67 . Moreover, since thesupport member 32 for the auricle can be taken out from theouter cover 22, as shown in FIG. Theauricle support member 32 whose shape best suits the shape of the user's auricle is carefully selected.

而且，如图3所示，通过将橡胶弹性体构成的塞盖52安装在耳塞24上，使其套管53紧附在外耳道的内周面上，能够在隔绝外部声音的同时防止内部声音的外漏，低音域的再现性良好。而且，塞盖52和耳廓支撑用部件32一起有助于将内置耳机11保持在耳廓61内。And, as shown in FIG. 3, by installing theplug cap 52 made of rubber elastic body on theearplug 24, making itssleeve 53 tightly attached to the inner peripheral surface of the external auditory canal, it is possible to prevent internal sound while isolating external sound. Leakage, good reproduction of the low range. Furthermore, theplug cap 52 and theauricle support member 32 together contribute to holding the built-inearphone 11 in theauricle 61 .

上面基于图示例对本发明进行了说明，但其具体结构不限于此。例如外罩22也可以不具有耳塞24。The present invention has been described above based on the illustrated examples, but its specific structure is not limited thereto. For example, theouter cover 22 may also not have theearplugs 24 .

另外，对于耳廓用支撑部件32，在耳廓卡止部38的外周面形成凹凸而进一步减少和耳廓的接点，可提高佩带感，或者根据情况为了进一步赋予弹性，也可将耳廓卡止部38的环部形成为波纹状，或者电车导电弓状。而且，耳廓卡止部38没有必要一定为环状，也可以为从安装基部33的一部分向侧边突出设置的臂状。In addition, for thesupport member 32 for the auricle, unevenness is formed on the outer peripheral surface of theauricle locking part 38 to further reduce the contact point with the auricle, which can improve the wearing feeling. The ring portion of thestop portion 38 is formed in a corrugated shape, or in a pantograph shape. Furthermore, theauricle locking portion 38 does not necessarily have to be ring-shaped, and may be an arm-shape protruding sideways from a part of the mountingbase 33 .
