  Hereinafter, embodiments of an earphone device of the present invention will be described with reference to the accompanying drawings. The embodiment described below is an embodiment of the present invention, and the present invention is not limited to the following embodiments.

(Embodiment 1)
FIG. 1 is a diagram simply illustrating an example of a configuration of an earphone device with a microphone according to a first embodiment of the present invention.

  In FIG. 1, 10 is an earphone device with a microphone, 101 is an earphone base, 101 is an earphone main body attached to the earphone base 100, 102 is a microphone arm attached to the earphone base 100 and extending forward, and 103 is provided at the tip of the microphone arm 102. The microphone 104 is a cable for electrically connecting the earphone main body 101 and the microphone 103 to the outside, and 105 is an ear hook arm.

  The ear arm 105 is formed in a shape corresponding to the shape of the ear shell so as to be hung on the user's ear shell. The ear-hanging arm 105 according to the first embodiment extends from the ear-hanging arm 105 and is in contact with the upper part of the ear shell base of the user above the mounting position of the earphone main body 101 in the ear-hanging arm 105 when the apparatus is used. It extends from the auxiliary arm 106 and the ear arm 105 and comes into contact with the lower part of the ear shell base of the user below the mounting position of the earphone main body 101 in the ear arm 105 when the apparatus is used. A lower auxiliary arm 107 extending to the shell side.

  Note that the earphone device with a microphone 10 shown in FIG. 1 is for the left ear.

  FIG. 2 is an external view illustrating an example of a state in which the microphone-equipped earphone device 10 according to the first embodiment is worn on the user.

  In FIG. 2, 201 is a so-called ear shell. FIG. 3 shows a state in which the ear hanger arm 105 is hung on the user's ear shell 201 and the microphone 102 is arranged near the user's mouth.

  In FIG. 2, the upper auxiliary arm 106 above the ear hook arm 105 is not shown hidden behind the ear shell 201 in the drawing. Further, although the lower auxiliary arm 107 below the ear hook arm 105 is illustrated on the outside from the ear shell 201, the lower auxiliary arm 107 may be formed so as to be hidden behind the ear shell 201.

  FIG. 3 is an external view showing an example in which a state in which the earphone with microphone of Embodiment 1 is attached to a user is enlarged and the back side of the earshell 201 is indicated by a broken line.

  In FIG. 3, 301 indicated by a broken line is a root of the ear shell 201 (hereinafter referred to as an ear shell root). As shown in FIG. 3, the upper auxiliary arm 106 contacts the upper portion of the ear shell root 301, and the lower auxiliary arm 107 passes through the ear shell root 301 to the lower portion of the ear shell root 301, which is substantially opposed to the upper contact position. Abut. In FIG. 3, only the upper auxiliary arm 106 and the lower auxiliary arm 107 are in contact with the ear shell base 301, and the contact surface 105 c of the ear hook arm 105 is not in contact with the ear shell base 301. Of course, the contact surface 105c of the arm 105 may be formed to contact the ear shell base 301.

  Here, in the first embodiment, the ear hook arm 105, the upper auxiliary arm 106, and the lower auxiliary arm 107 are integrally formed of an elastic material such as elastomer or rubber, for example. Therefore, the ear hook arm 105, the upper auxiliary arm 106, and the lower auxiliary arm 107 can be bent in any direction, for example, in the vertical and horizontal directions or the front and back directions in the figure. As a result, when the apparatus is used, not only the support by the microphone 103 and the ear hanger arm 105 but also the upper auxiliary arm 106 and the lower auxiliary arm 107 can effectively improve the mounting sensitivity and prevent mounting displacement. However, it can be molded with a simple structure.

  The integral molding is merely an example, and the ear hook arm 105, the upper auxiliary arm 106, and the lower auxiliary arm 107 may be molded and attached using different materials. When separately molded, the ear hook arm 105, the upper auxiliary arm 106, and the lower auxiliary arm 107 can be made of different materials, respectively, so that the ear hook arm 105 is made of a highly rigid resin and the upper auxiliary arm 106. Since the lower auxiliary arm 107 directly hits the user's ear, the lower auxiliary arm 107 may be made of an elastic material such as rubber or elastomer. In this way, it is possible to configure an earphone device with a microphone that has high strength and has a good wearing feeling when worn on the ear. Further, the upper auxiliary arm 106 and the lower auxiliary arm 107 may be formed integrally or separately, and inserted into a corresponding hole (not shown) of the ear hook arm 105. Of course, the ear-hanging arm 105, the upper auxiliary arm 106, and the lower auxiliary arm 107 may be formed hollow with a flexible material.

  On the other hand, the earphone base 100 and the earphone main body 101 are formed of ABS resin harder than the ear hook arm 105, the upper auxiliary arm 106, and the lower auxiliary arm 107. Needless to say, the earphone base 100 or the like may be molded or covered with an elastic material such as an elastomer or rubber having the same quality as the ear hook arm 105 or the upper auxiliary arm 106 or the like.

  In the first embodiment, as shown in FIGS. 1 and 3, the upper auxiliary arm 106 has an open end 106 a at one end close to the earphone main body 101, and the other end far from the earphone main body 101. It is a fixed end 106 b fixed to the ear hook arm 105, and is formed in an arc shape so as to follow the shape of the ear shell root 301.

  The lower auxiliary arm 107 has fixed ends 107 a and 107 b fixed to the ear hook arm 105 at both ends. Thus, when the device 10 is hung on the user's ear, normally, the open end 105b of the ear hanger arm 105 to which the lower auxiliary arm 107 fixed at both ends is fixed is expanded and hung on the user's ear shell root 301. However, since the lower auxiliary arm 107 does not have a protruding portion or a tip portion such as an open end, it is possible to prevent the protruding portion or the tip portion such as an open end from hitting or catching on the ear shell base 301. It is possible to prevent the wearability from being impaired.

  2 and 3, which will be described later, it is clear that the lower auxiliary arm 107, which is fixed at both ends to be a double-supported beam, supports the ear handle base 301 from below and cantilever with a greater degree of freedom. Since the upper auxiliary arm 106 that is fixed to one end as a beam supports the ear handle base 301 so as to sandwich the ear handle base 301 from above, it is possible to improve the wearing feeling and to support it reliably.

  Further, in the first embodiment, the open end 106a on the left side of the upper auxiliary arm 106 in the drawing is the attachment end 105a side of the earphone base 100 in the ear hook arm 105, while the fixed end 106b of the upper auxiliary arm 106 is the ear hook. The arm 105 is fixed to the open end 105b side facing the mounting end 105a side of the earphone base 100. Thus, the open end 105b of the ear hook arm 105 is pulled in the α direction in the figure by being pulled by the microphone 103, the microphone arm 102, etc. in the direction of the mouth with the ear hook arm 105 being hung on the ear shell 201. That is, when the ear hook arm 105 bends in the expanding direction, the open end 106a on the left side in the figure of the upper auxiliary arm 106 moves in the vertical direction in the figure, so that it strongly and elastically abuts on the root of the ear shell. Therefore, the microphone-equipped earphone device 10 can be held more reliably.

  Further, in the first embodiment, the lower auxiliary arm 107 is curved in a convex shape toward the earphone main body 101 side near the lower fixed end 107a, while a concave shape closer to the earphone main body 101 side is closer to the upper fixed end 107b. It is curved into an S shape that is curved in a straight line. As a result, the lower auxiliary arm 107 is easily bent as compared with the case where the entire lower auxiliary arm 107 is curved in a convex shape toward the earphone main body 101, and the feeling of wearing on the ear shell is improved.

  In the first embodiment, as shown in FIG. 3, the contact surface 106c of the upper auxiliary arm 106 to the ear shell root 301, the contact surface 107c of the lower auxiliary arm 107 to the ear shell root 301, The contact surface 105 c of the hanging arm 105 with the ear shell base 301 is formed to be flush with the shape of the ear shell base 301, that is, the fixed end 106 b of the upper auxiliary arm 106 and the lower auxiliary arm 107 are fixed. The end 107b and the contact surface 105c of the ear hook arm 105 are formed without a step. Thereby, in the state where the ear hook arm 105 is hung on the ear shell 201, the ear shell root contact surfaces 106 c and 107 c in the upper auxiliary arm 106 and the lower auxiliary arm 107, and the ear shell root contact surface in the ear hook arm 105. However, the projections and the like do not contact the ear shell, and this also improves the feeling of wearing the ear shell. It should be noted that the contact surface of the upper auxiliary arm 106 and the lower auxiliary arm 107 with the ear shell and the ear shell base contact surface of the ear hook arm 105 are stepped and of course may not be formed flush with each other. Good.

  Further, in the first embodiment, as shown in FIG. 1, the cut cross-sectional areas of the upper auxiliary arm 106 and the lower auxiliary arm 107 along the I-I line and the II-II line are larger than the cut cross-sectional area of the ear hook arm 105. It is small. Therefore, the upper auxiliary arm in the I-I line, II-II line direction, or one direction perpendicular to the direction, and further in both the I-I line, II-II line direction and the direction perpendicular thereto. 106 and the lower auxiliary arm 107 are formed narrower than the width of the ear hook arm 105. Thereby, even if the same elastic material is used, the ear hook arm 105 that supports the earphone base 100 can be configured more firmly than the upper auxiliary arm 106 and the lower auxiliary arm 107, while the upper auxiliary arm 106 and the lower auxiliary arm 107 can be configured. Since the arm 107 can be configured to be softer than the ear-hanging arm 105, this also improves the feeling of wearing the ear shell. Of course, the cut cross-sectional area of the upper auxiliary arm 106 and the lower auxiliary arm 107 may be the same as the cut cross-sectional area of the ear hook arm 105.

  FIG. 4 is a diagram showing an example of a detailed external appearance of the microphone-equipped earphone device according to the first embodiment of the present invention, and FIG. 5 is a diagram showing an example of a detailed external perspective view thereof.

  4A is a detailed top view of the earphone device with a microphone according to the first embodiment, FIG. 4B is a front view thereof, FIG. 4C is a detailed bottom view thereof, and FIG. 4D is a detailed back view thereof. FIG. 4 (e) shows a detailed left side view thereof, and FIG. 4 (f) shows a detailed right side view thereof. Note that the earphone device with microphone 10 shown in FIG. 4 is for the left ear, as in FIG.

  In FIG. 4, the cable 104 is omitted from the middle. Further, unlike the simple configuration diagram shown in FIG. 1, FIG. 4 shows a bush 104 a for connecting the cable 104 to the earphone base 100.

  As is clear from FIGS. 4 and 5, the upper auxiliary arm 106 and the lower auxiliary 107 are formed to be thinner than the ear hook arm 105, and even if integrally formed with the ear hook arm 105, the ear hook arm It is easier to bend than 105.

  As described above, when the microphone-equipped earphone 10 of the first embodiment configured as shown in FIGS. 1 to 5 is attached, the ear-hook arm 105 is attached to the ear shell root 301 as shown in FIGS. The earphone body 101 is inserted into the ear canal of the ear. Then, as shown in FIG. 2, the microphone 103 comes near the mouth.

  At this time, as shown in FIG. 3 and the like, the upper auxiliary arm 106 is elastically brought into contact with the upper portion of the ear shell base 301 while being bent and deformed, while the lower auxiliary arm 107 is also deformed and deformed at the lower portion of the ear shell base 301. By abutting with elasticity, the upper auxiliary arm 106 and the lower auxiliary arm 107 sandwich and support the ear shell root 301 with elasticity from above and below.

  At this time, the upper auxiliary arm 106 and the lower auxiliary arm 107 are configured to be thinner than the ear hanging arm 105 and have elasticity, so that the upper auxiliary arm 106 and the lower auxiliary arm 107 are appropriately deformed according to the size of various ears to form the ear shell root 301. Since it comes into contact, there is an effect of stabilizing the mounting position on the ear.

  That is, the upper auxiliary arm 106 and the lower auxiliary arm 107 have elasticity and come into contact with the ear shell base 301, so that even if they are worn for a long time regardless of the size of the ear, there is no feeling of pressure. Furthermore, the upper auxiliary arm 106 and the lower auxiliary arm 107 support the base of the ear shell so as to be sandwiched from above and below, so that there is no possibility that the mounting position is shifted. In addition, since the upper auxiliary arm 106 and the lower auxiliary arm 107 support the ear shell base 301 so as to be sandwiched between the upper and lower directions in a substantially opposite position, no load is applied to the ear hole into which the earphone body 101 is inserted, and the ear hole is not It rarely hurts.

  Further, in the first embodiment, the upper auxiliary arm 106 of the two auxiliary arms is cantilevered to be greatly deformed to cope with various ear sizes, and the lower auxiliary arm 107 has both S-shaped shapes. Since the cantilever can withstand a load larger than that of the upper auxiliary arm 106 of the cantilever, this also has an effect of stabilizing the mounting position on the ear.

  As described above, in the ear-hook type earphone device 10 according to the first embodiment, the ear-hook arm 105 that is hung on the user's ear when the device is used extends from the ear-arm 105 and is used when the device is used. The upper auxiliary arm 106 that contacts the upper part of the user's ear shell base 301 above the mounting position of the earphone main body 101 on the arm 105, and extends from the ear hook arm 105, and the earphone main body 101 of the ear hook arm 105 when using this apparatus. Since the lower auxiliary arm 107 is in contact with the lower part of the user's ear shell base 301 below the mounting position, the upper auxiliary arm 106 and the lower auxiliary arm 107 move the ear shell base 301 up and down when using this apparatus. Since the support is provided so as to be sandwiched from the direction, the displacement of the mounting position can be prevented as much as possible.

  As a result, in the earphone device with a microphone, if the mounting position is displaced, the microphone 103 may be displaced from the mouth and it may be difficult to pick up the sound. However, in the ear-hook earphone device 10 with a microphone according to the first embodiment, Since the auxiliary arm 106 and the lower auxiliary arm 107 securely hold the ear shell base 301 to support the apparatus, it is possible to prevent the displacement of the mounting position and to make it difficult to pick up the sound more reliably than in the past. Can be prevented. In the present invention, of course, the microphone 103 is not provided and is still effective.

  In the first embodiment, since the ear hook arm 105, the upper auxiliary arm 106, and the lower auxiliary arm 107 are integrally formed of an elastic material such as an elastomer, the upper auxiliary arm 106, the lower auxiliary arm 107, and the like. Thus, it is possible to mold with a simple structure while effectively preventing mounting deviation and mounting slippage.

  In the first embodiment, the upper auxiliary arm 106 has a fixed end 106b supported at one end by the ear hook arm 105 and the other end an open end 106a, while the lower auxiliary arm 107 has both ends at the ear hook arm. Since it is composed of fixed ends 107a and 107b supported by 105, one of the two auxiliary arms can be cantilevered and greatly deformed. The other has an effect of stabilizing the position with respect to the ears by having both ends of a bow shape.

  In the first embodiment, the fixed end 106b of the upper auxiliary arm 106 that is open at one end is fixed to the side of the ear hook arm 105 that faces the mounting end 105a side 105a of the earphone base 100. When bent in the expanding direction, the open end 106a of the upper auxiliary arm 106 is more strongly and elastically in contact with the ear shell root, and can hold the ear shell root 301 more effectively.

  Further, in the first embodiment, the lower auxiliary arm 107 that is fixed at both ends is curved in an approximately S shape, so that it is easy to bend and a feeling of wearing on the ear shell is improved.

  Further, in the first embodiment, the contact surface of the upper auxiliary arm 106 and the lower auxiliary arm 107 with the ear shell root 301 and the contact surface 105 c of the ear hook arm 105 with the ear shell root 301 are the ear shell root 301. Since the projections and the like do not come into contact with the ear shell, the feeling of wearing the ear shell is improved in this respect as well.

  In the first embodiment, the cut cross-sectional areas of the upper auxiliary arm 106 and the lower auxiliary arm 107 are smaller than the cut cross-sectional area of the ear hook arm 105. Even if it is molded, the ear hook arm 105 that supports the earphone base 100 can be configured more firmly than the upper auxiliary arm 106 and the lower auxiliary arm 107, while the upper auxiliary arm 106 and the lower auxiliary arm 107 can be configured as the ear hook arm 105. It can be configured to be softer, and also in this respect, the feeling of wearing on the ear shell is improved.

  In addition, since this apparatus has a two-stage structure of the ear hook arm 105 and the auxiliary arms 106 and 107, even if the auxiliary arms 106 and 107 inside the ear hook arm 105 are broken or removed. This can be handled by the ear-hanging arm 105.

(Embodiment 2)
In the first embodiment, the connection between the earphone base 100 and the earphone arm 105 for the earphone device has not been described. In the second embodiment, the connection between the earphone base 100 and the eararm 105 will be described. .

  FIG. 6 is a perspective view illustrating an example when the earphone base 100 and the ear hook arm 105 are detachable in the second embodiment.

  As shown in FIG. 6, in the second embodiment, the earphone base 100 and the ear hook arm 105 are formed separately, and the ear hook arm 105 is detachably attached to the earphone base 100. When the ear hook arm 105 in the second embodiment is attached to the earphone base 100, for example, the state shown in FIG.

  For this reason, a pair of upper and lower parts is placed on the rear end 100b of the earphone base 100, that is, on the side facing the mounting end 100a of the microphone 102, so that the ear hanging arm 105 can be detachably attached to the earphone base 100 of the second embodiment. The upper receiving groove 100b1 and the lower receiving groove 100b2 are formed.

  On the other hand, in the ear hook arm 105 of the second embodiment, an upper insertion piece 105a1, which is a pair of upper and lower insertion pieces inserted into the pair of upper and lower upper receiving grooves 100b1 and 100b2 of the earphone base 100, respectively. A piece 105a2 is provided.

  Here, in the second embodiment, when the ear arm 105 is attached to the earphone base 100, for example, as shown in FIG. 5 of the first embodiment, the upper insertion piece 105a1 and the lower insertion piece 105a2 of the ear hook arm 105 The connecting portion 105d connecting the two is flush with the rear end 100b of the earphone base 100. However, when the ear hook arm 105 is attached to the earphone base 100, the connecting portion 105d of the ear hook arm 105 protrudes from the rear end 100b of the earphone base 100 without being flush with the rear end 100b of the earphone base 100. You may do it. If the connection part 105d of the ear hook arm 105 is formed so as to protrude from the rear end 100b of the earphone base 100, the chance of the connection part 105d of the soft ear hook arm 105 coming into contact with the ear or the like increases and the material is hard. Since the chance of the rear end 100b of the earphone base 100 coming into contact with the ear is reduced, the wearing feeling is improved in this respect as well. In the first embodiment, the connecting portion 105d of the ear hook arm 105 may protrude from the rear end 100b of the earphone base 100 without being flush with the rear end 100b of the earphone base 100.

  7A is a top view of the ear hook arm 105 according to the second embodiment, FIG. 7B is a front view thereof, FIG. 7C is a bottom view thereof, FIG. 7D is a back view thereof, and FIG. 7 (e) is a left side view thereof, and FIG. 7 (f) is a right side view thereof.

  7 (a), (c), (e), and (f), the ear hook arm 105 of the second embodiment shown in FIG. 6 and FIG. Since the upper auxiliary arm 106 and the lower auxiliary arm 107 are formed to be asymmetrically curved so as to approach the user's face from the lower insertion piece 105a2, as in FIG. is there.

Convex portions are formed on the pair of upper and lower upper insertion pieces 105a1 and 105a2 on the ear hook arm 105, while concave portions 105a12 and 105a22 are formed in the upper and lower receiving grooves 100b1 and 100b2 on the rear end 100b of the earphone base 100, respectively. Of course, they may be formed, or the concave portions 105a12 and 105a22 and the convex portions fitted thereto may not be provided.

  Thus, when the pair of upper and lower upper insertion pieces 105a1 and 105a2 of the ear hook arm 105 are respectively inserted into the upper and lower receiving grooves 100b1 and 100b2 of the rear end 100b of the earphone base 100, the upper insertion of the ear hook arm 105 is performed. The recesses 105a12 and 105a22 of the piece 105a1 and the lower insertion piece 105a2 are fitted into the respective protrusions of the upper and lower receiving grooves 100b1 and 100b2 of the earphone base 100, thereby effectively preventing the ear-hook arm 105 from falling off the earphone base 100. be able to.

  Therefore, according to the second embodiment, the same effects as those of the first embodiment can be obtained, and the ear hook arm 105 and the earphone base 100 can be separately configured, and the ear hook arm 105 can be attached to and detached from the earphone base 100. Therefore, even when the ear arm 105 is damaged or when the ear arm 105 dedicated to the left and right ears is prepared, only the ear arm 105 can be easily replaced.

  FIG. 10 is a diagram showing an example in which two replaceable ear hook arms 105A and 105B are prepared, for example.

  As shown in FIG. 10, in the second embodiment, even with one earphone base 100, it is possible to prepare two ear hanging arms 105A and 105B that are detachable, for example, to be replaceable. Of course, three or more types such as large, medium, and small may be prepared. In addition, not only preparing replaceable large and small ear hook arms 105A and 105B, the replaceable left and right ear hook arms 105 may be facilitated respectively, and furthermore, the left and right ear hook arms 105 may be respectively large and small. You may make it prepare two or more.

  Accordingly, the earphone base 100 can be used for both large and small earphones for men and women, even if one earphone base 100 is exchangeable by changing the size of the large or small size asymmetrical ear-hook arm. It is possible to improve the wearing feeling.

  Further, in the second embodiment, the upper receiving groove 100a1 and the lower receiving groove 105a2 of the earphone base 100 and the upper insertion piece 105a1 and the lower insertion piece 105a2 of the ear hook arm 105 respectively have a groove or piece width in the vertical direction. Therefore, it is possible to prevent the ear arm 105 from being attached upside down with respect to the earphone base 100.

  Further, in the second embodiment, when the upper receiving groove 100a1 and the lower receiving groove 105a2 of the earphone base 100 and the upper insertion piece 105a1 and the lower insertion piece 105a2 of the ear hook arm 105 are completely inserted. Further, since the convex portions and the concave portions 105a12 and 105a22 that fit each other are provided, it is possible to effectively prevent the ear-hanging arm 105 from falling off the earphone base 100.

In the second embodiment, when the ear hook arm 105 is attached to the earphone base 100, the connecting portion 105 d of the ear hook arm 105 is not flush with the rear end 100 b of the earphone base 100. If the connecting portion 105d is formed so as to protrude from the rear end 100b of the earphone base 100, the chance that the connecting portion 105d of the soft ear-hanging arm 105 contacts the ear or the like increases. Since the chance of the rear end 100b coming into contact with the ear is reduced, the feeling of wearing is also improved in this respect.
