Description

  In the present invention, when a housing with a built-in speaker unit is attached to the concha side, the housing is adapted to various ear shapes and sizes that differ depending on individuals so that the housing does not easily fall off. It is related to the earphone.

  Patent Document 1 discloses an example of a general canal type earphone. FIG. 6 shows an example described in Patent Document 1. In FIG. 6, an earphone 24 includes a housing 27 that houses a speaker unit and forms an earphone body, a cylindrical external ear canal insertion portion 22 that protrudes from the front side of the housing 27, and an external ear canal insertion portion 22. The ear canal sealing member 21 is attached so as to surround the opening 23 provided on the distal end side, and the connection cord 26 is drawn out from the housing 27 via the cord holding portion 25.

  The ear canal sealing member 21 includes an attachment portion 21a to the ear canal insertion portion 22, and an elastic contact piece portion 21b that is folded in an arc shape from the distal end side to the proximal end portion side of the attachment portion 21a. Yes.

  According to the earphone 24 disclosed in Patent Document 1, when the earphone 24 is attached to the auricle, the elastic contact piece 21b in the ear canal sealing member 21 is elastically deformed so as to follow the inner side surface shape of the ear canal, and the contact portion is defined. It will be sealed. Therefore, when the earphone 24 is worn on the user's ear, the sealed state is secured by the elastic contact piece 21b, so that the sound from the outside can block the intrusion, and the internal sound In addition to preventing leakage, the reproducibility of the low frequency range can be improved.

  However, the conventional canal type earphone disclosed in Patent Document 1 is elastically deformed so that the elastic contact piece 21b follows the inner surface shape of the ear canal and seals the contact portion. In some cases, it may not always be possible to generate sufficient adhesion, and it will not be enough to reliably prevent falling off from the auricle side due to external force, causing loosening that reduces the sealing performance when worn. there were.

  Therefore, in Patent Document 2, in addition to the components of the conventional canal-type earphone, an attachment portion provided with a cord holding portion and an earphone housing on the ear canal side are positioned in the vicinity of the rosary when the earphone housing is inserted. Thus, there is described an earphone including a loop-like elastic support portion that protrudes through a crown portion that elastically deforms against a side wall surface that partitions the concha side and the opposite wheel side. The elastic support part described in Patent Document 2 makes elastic contact with the side wall surface of the auricle when the housing is inserted into the ear canal side of the auricle, making it difficult to drop off when the earphone is worn. .

  However, in the invention described in Patent Document 2, the components of the entire earphone are fixed, and the range that can be flexibly adapted to the shape of the user's ear is limited. In addition, the flexibility of the elastic body has a limitation on the material, and there is room for improvement in order to widely cope with the shape of individual ears which varies greatly depending on age, sex, and race.

  The invention described in Patent Document 3 does not secure the sealed state of the external ear canal due to the elastic contact piece when it is worn, blocks the entry of sound from the outside, and prevents the leakage of internal sound. In addition, the reproducibility of the bass range could not be improved. In addition, since the components of the entire earphone are fixed, there is room for improvement in order to deal widely with different ear shapes depending on individuals, as in the invention described in Patent Document 2.

  It is considered relatively easy for audio maker developers to design earphones in a general form, but individual differences in ear shape and size are recognized by biotechnological approaches, and audio maker developers Since there are divergences from the areas of interest such as acoustics, electronics, and plastic molding technology using molds, it is not easy to design earphones assuming individual differences in ear shape and size.

  In view of the above-mentioned problems of the prior art, the present invention is adapted to various ear shapes and sizes that vary depending on individuals when a housing incorporating a speaker unit is used on the concha side. It is intended to provide an earphone that does not easily fall off, blocks external sounds from entering, prevents internal sounds from leaking out, and has excellent reproducibility in the low range. .

  The present invention includes a housing that is held between the auricular side and the concha side when the speaker unit is incorporated and inserted into the external auditory canal side of the auricle, and is attached to the housing side from the auricular side. A pinion support member that prevents the pin from falling off, and the pinion support member is rotatably provided along the side wall surface that separates the concha side and the opposite wheel side so that the top end portion is on the above side. The main feature is that it is difficult to drop off when it is engaged with the wall.

  According to the present invention, when the housing side is inserted into the external auditory canal of the auricle, it can be held on the tragus side and the concha side, and by rotating the auricle support member, It can contact | abut via the top end part with respect to the side wall surface which partitions off a medial side and a wheel side. As a result, the housing side can be positioned so as to be held between the tragus side and the concha side, so that it can be reliably supported on the auricle side while preventing dropout when receiving external force. it can.

It is a side view of the said Example. It is a side view of the said Example. It is a front view which shows the use condition of the said Example. It is a perspective view which shows the example of the conventional earphone.

  Fig.1 (a) is a front view which shows the Example of the earphone 7 of this invention. Moreover, FIG.1 (b) is sectional drawing in alignment with line AA 'in Fig.1 (a). According to FIG. 1A, the earphone 7 includes a housing 2 and an auricle support member 1 disposed outside the housing 2, and the whole is configured.

  The auricular support member 1 shown in FIG. 1A includes a holding bar 1 a formed in a rod shape, and a rotating portion 1 b that is joined to the housing 2 and is configured to rotate relative to the housing 2. It consists of For attaching the auricle support member 1 to the housing 2, an appropriate attachment structure such as fitting of a shaft and a shaft hole can be applied. The shape of the holding bar 1a may be tapered or tapered. The length from the center of the rotating portion 1b to the tip of the holding bar 1a can be selected as long as the earphone 7 of the present invention can be prevented from falling off.

  The tip of the holding lever 1a is preferably covered with an elastic material that functions as an anti-slip material, such as an elastomer or silicone rubber that can be elastically deformed as an anti-slip material. The shape is preferable. The anti-slip may be configured to be detachable from the holding lever 1a.

  The auricle support member 1 may have the same configuration as the illustrated rotating portion 1b, or the tip of the holding lever 1a may be formed by a separate member. As a material of the tip of the holding lever 1a, for example, a soft material such as sponge having bubbles or a soft touch member may be used. By doing so, it is possible to flexibly adapt to differences in the size and shape of the individual ears.

  As shown in FIG. 1B, the housing 2 incorporates a speaker unit 6, and the speaker unit 6 includes, for example, a diaphragm (not shown) and a magnetic circuit that drives the diaphragm. In FIG. 1A, the external ear canal sealing member 3 provided on the front end surface of the housing 2 is inserted into the external ear hole 14 side of the auricle 13 shown in FIG. It is formed with an appropriate shape that can hold it. As shown in FIG. 3, the housing 2 is provided with a cylindrical outer ear canal insertion part 2a on the front end surface thereof, so that sound generated by the speaker unit 6 can be led out to the eardrum side via the ear canal insertion part 2a. It has become. A cord holding portion 4 extends from the outer peripheral portion of the rear end of the housing 2 toward the outside in the radial direction of the housing 2. The cord holding part 4 leads the connection cord 5 drawn from the speaker unit 6 in FIG. 1B to the outside.

  In FIG. 2, the central axis B indicates the rotational central axis of the auricle support member 1, and the central axis C indicates the central axis of the housing 2 and the external auditory canal insertion portion 2a. Therefore, when the present embodiment is used by a user, the central axis C coincides with the central axis of the user's ear canal. As shown in FIG. 2, the housing 2 has its sound emitting surface facing the same direction as the axis C in the ear canal direction, and the rotating portion 1 a of the auricular support member 1 rotates relative to the housing 2 and the axis B. It is equipped as such. When the auricle support member 1 is rotated with respect to the housing 2 in a state where this embodiment is used by the user, the auricle support member 1 is opposed to the auricle 16 side shown in FIG. The central axis B and the central axis C are set to form a predetermined angle so as to rotate along the side wall surface 11 that partitions the wheel 15 side (see FIG. 2). As shown in FIG. 3, the heel BC is preferably 20 ° to 40 °, particularly preferably 31.5 °, considering the difficulty of falling off from the shape of the human ear. By configuring the housing 2 and the auricle support member 1 at such angles of the axes B and C, the auricle support member 1 is in the side wall surface 11 in a state where the housing 2 is held in the outer ear hole 14. Therefore, the holding force of the housing 2 by the outer ear hole 14 and the posture holding force obtained by engaging the auricle support member 1 with the side wall surface 11 can be obtained, and the earphone 7 can be prevented from loosening. It can be made more reliable.

  The opening 3a of the ear canal sealing member 3 is oriented in the direction of the ear canal when the user is wearing the ear, like the opening 23 of the conventional example shown in FIG. Further, in the ear canal insertion portion 2a provided in the housing 2 of the earphone 7, the ear canal sealing member 3 is connected to the ear canal insertion portion via the attachment portion 3c in the same manner as the attachment portion 21a to the ear canal insertion portion 22 of the conventional example shown in FIG. The elastic contact piece 3b is attached to 2a and can be contacted while being elastically deformed so that the inner peripheral surface of the ear canal is sealed when worn.

  The ear canal insertion part 2a provided integrally with the housing 2 is provided with the ear canal sealing member 3 that is brought into close contact with the wall of the ear canal with elastic deformation, so that the user's ear canal is elastically deformed while the ear canal sealing member 3 is elastically deformed. The 14 wall surfaces can be brought into contact so as to be sealed. As a result, it is possible to prevent the external sound from being cut off and the internal sound from leaking out, and to improve the reproducibility of the low sound range. Such an effect brought about by the ear canal sealing member 3 prevents the earphone from falling off by preventing the posture holding force obtained by the auricle support member 1 and the mounting force of the housing 2 by the outer ear hole 14 from being loosened. Can be.

  As shown in FIG. 5, when the housing 2 is attached to the outer ear hole 14 under the positional relationship in which the cord holding part 4 from which the connection cord 5 is drawn is guided toward the auricle 13, the auricle support is supported. The top end side of the holding bar 1a in the member 1 rotates and moves along the side wall surface 11 that partitions the concha 16 side and the opposite wheel 15 side, so that the distance and shape of the outer ear hole 14 and the side wall surface 11 are personal. Even if it is different, the top end portion of the holding bar 1a can be engaged with the side wall surface 11. If the cord holding part 4 from which the connection cord 5 is pulled out is designed to face the upper side of the auricle 13 with the earphone attached to the user's ear as in the example shown in FIG. Can be wrapped around the upper half of the auricle 13, so that the earphone can be held more stably. However, whether or not the cord holding unit 4 is designed to face upward of the auricle 13 with the earphone attached to the user's ear is arbitrary, and may be designed to face downward.

(Dropping test)
The conventional canal type earphone 24 shown in Prior Art Document 1 and the earphone 7 of the present invention are attached to the right ear of the same subject, and the same weight is attached to the cable of each earphone at the same position of the cable. A dropout test was conducted. In this test, the weight of the weight was increased in units of 10 g, and a test was performed to determine whether each earphone dropped from the pinna of the subject's right ear.

  When the subject was wearing the conventional canal-type earphone 24 and the weight was increased by 10 grams, the external ear of the subject's right ear was displaced at a weight of 80 g. In addition, at 100 g or more, dropping occurred from the subject's pinna.

  When the subject was wearing the earphone 7 according to the present invention and the weight weight was changed by 10 g, the earphone of the present invention did not fall off from the subject's auricle even when the weight weight was increased to 300 g. From the above results, it has been found that the presence of the auricle support member 1 like the earphone 7 according to the present invention has an advantage in preventing displacement or dropout. In addition, in the said Example, the angle which the said center axis line B and the center axis line C in FIG. 2 of the earphone 7 which concerns on this invention makes a predetermined angle shall be 31.5 degrees, and the same also in 20 degrees-40 degrees Results were obtained.

  The above is a description of the earphone according to the present invention based on the illustrated embodiment, and the specific configuration thereof is not limited thereto. For example, the housing 2 may not have the ear canal sealing member 3. In the illustrated embodiment, the auricle support member 1 is rotatably fitted to the axial end portion of the housing 2, but may be configured to rotate along the outer peripheral surface of the housing 2. .
