FIG. 4B is a bottom view showing the earphone according to the first embodiment. FIGS. 5A and 5B are diagrams illustrating an example of a state where the earphone according to the first embodiment is gripped. Hereinafter, the earphone according to the first embodiment will be described with reference to FIGS. 1 to 5B.

  As shown in FIGS. 1 to 4B, the earphone 1 includes a main body 11, an insertion portion 12, and a cable lead-out portion 13. The insertion part 12 and the cable lead-out part 13 are respectively formed continuously on the main body 11.

  The main body 11 includes a front surface 111, an outer surface 112, and a back surface 113. The main body 11 includes a driver main body 10 and a protruding portion 17. The driver main body 10 is formed in a substantially cylindrical shape. The shape of the driver body 10 is not limited to a cylindrical shape, and may be a polygonal column shape, a spherical shape, or the like. The driver main body 10 has a driver (not shown) built in the internal space. Usually, since the driver is cylindrical, if the driver main body 10 is cylindrical, it is easy to be accommodated and the useless space can be reduced.

  The main body 11 may be provided with a vent hole (not shown) that connects the internal space and the outside to the driver main body 10. Thereby, the operation | movement of the driver arrange | positioned in the internal space of the driver main body 10 can be improved, and a sound can be reproduced more correctly. Further, by controlling the size of the air holes, it is possible to mainly adjust the sound quality in the bass region.

  The insertion portion 12 is formed so as to protrude outward from the outer surface 112 and the rear surface 113 of the driver body 10. The insertion portion 12 is fitted into the ear canal by being inserted into the ear canal. The surface of the insertion part 12 is covered with a flexible resin or the like. Examples of the resin used on the surface of the insertion portion 12 include silicone rubber, polyurethane resin, and epoxy resin.

  The cable lead-out portion 13 is generally formed in a cylindrical shape. One end of the cable lead-out portion 13 is connected to the driver main body 10, and the other end is connected to the cable 14. The other end of the cable lead-out portion 13 is formed so that the rear side is shorter than the front side when it is attached to the ear. This makes it easier for the cable 14 to bend to the rear side when attached to the ear. Therefore, the cable 14 is easily routed to the back side of the user.

  The cable lead-out portion 13 is formed from a material that is elastic to some extent. Since the cable 14 is usually made of a flexible material, it is possible to prevent the cable 14 from being bent suddenly near the other end of the cable lead-out portion 13.

  The main body 11 has a protrusion 17. The protrusion 17 has a first end 31 and a second end 32 located on the opposite side of the first end 31. The first end 31 is located on the side in contact with the concha Y when the earphone 1 is worn. The first end 31 is generally formed as a part concentric with the surface 111. That is, the first end 31 is formed in a smooth arc. For this reason, the first end 31 has a shape that easily fits the concha Y. Further, the first end 31 can reduce a sense of discomfort when contacting the concha Y when the earphone 1 is worn.

  The protrusion 17 is detachable from the driver body 10. The attachment and detachment of the protrusion 17 with respect to the driver main body 10 will be described later.

  The surface of the protrusion 17 has flexibility. Examples of the resin used on the surface of the protruding portion 17 include silicone rubber, polyurethane resin, and epoxy resin. Thereby, the fit with respect to the concha Y can be further improved. The surface of the protrusion 17 may be provided with fine irregularities. Thereby, since friction arises between the surface of the protrusion part 17 and the concha Y, the fitting feeling with respect to the concha Y can be improved further.

  Note that there are a plurality of protrusions 17, which may have different sizes. For example, the protrusion 17 may have a plurality of types having different lengths from the first end 31 to the second end 32. In this case, since the protrusion 17 can be replaced according to the size of a person's ear, the fit to the concha Y can be further improved. It is also possible to use the earphone 1 with the protruding portion 17 removed.

  As shown in FIG. 2A, the main body 11 has an outer surface 112 having a first concave curved surface 21, a second concave curved surface 22, and a third concave curved surface 23 in the outer shape. The first concave curved surface 21, the second concave curved surface 22, and the third concave curved surface 23 are curved inwardly of the main body 11. The first concave curved surface 21 and the third concave curved surface 23 are formed across the driver main body 10 and the protruding portion 17. The second concave curved surface 22 is formed across the driver main body 10 and the cable lead-out portion 13. For this reason, as shown in FIG. 5A, when a person holds the earphone 1 with a finger, the finger is likely to fit. For example, the stomachs of the index finger F, the middle finger S, and the thumb T are likely to be along the first concave curved surface 21, the second concave curved surface 22, and the third concave curved surface 23, respectively. Thereby, a user's finger | toe easily fits the earphone 1, and operations, such as attaching the earphone 1 to an ear | edge or removing from an ear | edge, become easy.

  In addition, the 1st concave curved surface 21 and the 3rd concave curved surface 23 are not limited to what is formed over the driver main body 10 and the protrusion part 17 as shown to FIG. It should just be formed in any one of them. For example, a concave curved surface may be formed only on the projecting portion 17 as in the second embodiment described in detail later.

  Further, as shown in FIG. 5B, the first concave curved surface 21 and the third concave curved surface 23 are configured such that the concave curved surfaces face each other. Thereby, when attaching and detaching the protrusion 17 to / from the driver main body 10 of the main body 11, the first concave curved surface 21 and the third concave curved surface 23 are along the belly of the index finger F and thumb T, and the protrusion 17 is easily grasped. Therefore, the protrusion 17 can be easily attached and detached.

  As shown in FIGS. 3 (A) and 3 (B), a fourth concave curved surface 24 is formed at the connection portion between the driver main body 10 and the cable lead-out portion 13. The fourth concave curved surface 24 is curved inwardly of the main body 11. Thereby, a concave curved surface is formed on the front side. For this reason, by placing a finger along the fourth concave curved surface 24, it is easy to apply a force in a direction in which the earphone 1 is pushed into the ear.

  As shown in FIGS. 2 (A) and 2 (B), a convex curved surface 25 is formed at the other end of the cable lead-out portion 13. The convex curved surface 25 is curved outward from the cable lead-out portion 13 in a curved shape. Thereby, a convex curved surface is formed on the front side. A convex curved surface 25 is formed so as to be continuous with the third concave curved surface 23. For this reason, when the earphone 1 is viewed from the front, it has a beautiful appearance because the curves are continuous.

  In the present embodiment, four concave curved surfaces of the first concave curved surface 21, the second concave curved surface 22, the third concave curved surface 23, and the fourth concave curved surface 24 are configured, but at least one concave curved surface is formed. May be formed on the outer surface 112. For example, even when only the first concave curved surface 21 is configured, a portion that is easy to grip can be formed, so that it can be gripped stably.

  Moreover, although the 1st concave curved surface 21, the 2nd concave curved surface 22, the 3rd concave curved surface 23, and the 4th concave curved surface 24 are formed in curve shape, you may provide a fine unevenness | corrugation on the surface. Thereby, since friction arises between the 1st concave curved surface 21, the 2nd concave curved surface 22, the 3rd concave curved surface 23, and the 4th concave curved surface 24, and a finger | toe, it becomes easier to hold | grip.

  FIG. 6A is a front view showing the earphone according to the first embodiment in a state in which the protruding portion is removed. FIG. 6B is a top view showing the earphone according to the first embodiment in a state in which the protrusion is removed. FIG. 6C is a conceptual diagram for explaining an engaged state of the protruding portion according to the first embodiment with the driver main body. Hereinafter, the attachment / detachment of the protruding portion 17 with respect to the driver main body 10 will be described with reference to FIGS. 6 (A) to 6 (C).

  As shown in FIGS. 6A to 6C, the driver main body 10 has a recess 61 on the surface in contact with the protrusion 17. On the other hand, the protruding portion 17 has a convex portion 62 on the surface in contact with the driver main body 10. As a method for fitting the convex portion 62 into the concave portion 61, for example, a snap type is used. Therefore, the convex part 62 is detachably fitted in the concave part 61. Thereby, the protrusion 17 can be attached to and detached from the driver main body 10.

  In addition, the method of fitting the protrusion 62 into the recess 61 can be used as long as the protrusion 17 can be attached to and detached from the driver main body 10. For example, the method of forming the recessed part 61 and the convex part 62 with a different material is mentioned.

  If it demonstrates in detail, the recessed part 61 is formed with the raw material which does not have flexibility. Examples thereof include vinyl chloride and polypropylene. On the other hand, the surface of the protrusion part 17 has flexibility. For this reason, the convex part 62 is formed with the raw material which has flexibility. The shape of the convex portion 62 is slightly larger than the concave portion 61. Thereby, the convex part 62 can be closely_contact | adhered to the recessed part 61, deform | transforming by fitting the convex part 62 in the recessed part 61. FIG. Thereby, the convex part 62 can be detachably fitted in the concave part 61.

  Here, the driver body 10 includes a first concave curved surface 21, a second concave curved surface 22, and a third concave curved surface 23. For this reason, the driver main body 10 and the protrusion part 17 are easy to be hold | gripped with a finger, respectively. For this reason, even when the protrusion 17 is small, the protrusion 17 can be easily attached to and detached from the driver main body 10.

  FIG. 7 is a conceptual diagram for explaining an engagement state of the protrusion according to the second embodiment with the driver main body. Hereinafter, the engagement state of the protrusion according to the second embodiment with the driver body will be described with reference to FIG. In the second embodiment, the second embodiment is different from the second embodiment only in the engagement state of the projecting portion with the driver main body, and the description of other structures is omitted.

  As shown in FIG. 7, the earphone 7 includes a driver main body 70 and a protruding portion 77. The driver main body 70 is formed in a substantially cylindrical shape with a part protruding from the protruding portion 77 side. The driver main body 70 has a convex portion 72 on the surface in contact with the protruding portion 77. On the other hand, the protrusion 77 has a recess 71 on the surface in contact with the driver main body 70.

  As a method for fitting the convex portion 72 into the concave portion 71, for example, a snap type is used as in the first embodiment. Accordingly, the convex portion 72 is detachably fitted into the concave portion 71. Thereby, the protrusion 17 can be attached to and detached from the driver main body 70.

In addition, also in the fitting method of the convex part 72 to the recessed part 71, the method of forming the recessed part 71 and the convex part 72 from a different raw material can be used. In this case,
The convex portion 72 is formed of a material that does not have flexibility. Examples thereof include vinyl chloride and polypropylene. On the other hand, the recessed part 71 is formed with the raw material which has flexibility. Moreover, the shape of the convex part 72 is formed slightly larger than the concave part 71. As a result, the convex portion 72 can be brought into close contact with the concave portion 71 while being deformed by fitting the convex portion 72 into the concave portion 71. Accordingly, the convex portion 72 is detachably fitted into the concave portion 71. Thereby, the protrusion 17 can be attached to and detached from the driver main body 70.

  8A to 8C are conceptual cross-sectional views for explaining the protrusions according to the third embodiment. Hereinafter, the protrusion part which concerns on 3rd Embodiment is demonstrated, referring FIG. 8 (A)-(C). In the third embodiment, since only the protruding portion is different from the first embodiment, description of other structures is omitted.

  As shown in FIG. 8A, the earphone 8 includes a driver main body 80 and a protruding portion 87. The driver main body 80 has an internal space 81 and a vent hole 82 communicating with the internal space 81. The protrusion 87 has a structure that does not have a vent hole inside. By attaching the protruding portion 87 to the driver main body 80, the protruding portion 87 seals the internal space 81. Thereby, the followability of the driver existing in the internal space 81 can be improved, so that the sound quality can be adjusted.

  As shown in FIG. 8B, the earphone 8 includes a driver main body 80 and a protrusion 88. The protrusion 88 includes a vent hole 83. The vent hole 83 is formed to be narrower than the vent hole 82. By attaching the protrusion 88 to the driver main body 80, the air hole 83 communicates with the air hole 82. The vent 83 communicates the internal space 81 of the driver main body 80 with the outside. Therefore, the amplitude of the driver existing in the internal space 81 can be improved, and the sound in the bass region can be made stronger.

  As shown in FIG. 8C, the earphone 8 includes a driver main body 80 and a protruding portion 89. The protruding portion 89 includes a vent hole 84. The vent hole 84 is formed to have the same thickness as the vent hole 82. By attaching the protruding portion 89 to the driver main body 80, the vent hole 84 communicates with the vent hole 82. The ventilation hole 84 allows the internal space 81 of the driver main body 80 to communicate with the outside. Therefore, the amplitude of the driver existing in the internal space 81 can be further improved, and the sound in the bass region can be further strengthened.

  As described above, the sound quality can be adjusted by changing the shapes of the air holes 83 and the air holes 84. Further, the shapes of the air holes 83 and the air holes 84 are not limited thereto, and can be appropriately changed to a wave shape, a zigzag shape, or the like. The sound can also be adjusted by providing a filter in the middle of the vent 83 and vent 84.

  Therefore, the sound quality can be adjusted without changing the driver main body 80 by changing the protrusion 87, the protrusion 88, and the protrusion 89 from the driver main body 80.

  FIG. 9 is a conceptual cross-sectional view for explaining a protrusion according to the fourth embodiment. Hereinafter, the protrusion according to the fourth embodiment will be described with reference to FIG. 9. In the fourth embodiment, only the protrusions are different from the first embodiment, and the description of other structures is omitted.

  As shown in FIG. 9, the earphone 9 includes a driver main body 10 and a protruding portion 97. The protrusion 97 has a branched shape. More specifically, the protrusion 97 includes a first protrusion end 98 and a second protrusion end 99. The protruding portion 97 branches from the second end 32 toward the first end 31, and the first end 31 constitutes a first protruding end 98 and a second protruding end 99, respectively. That is, the first end 31 is formed in two places discontinuously. Two places in contact with the concha Y at the first end 31 are formed. For this reason, the force applied from the protrusion 97 to the concha Y is distributed in two directions. Thereby, the fitting feeling to the ear | edge of the protrusion part 97 can be improved. Moreover, since the protrusion part 97 is not continuously formed in the circumferential direction of the driver main body 10, weight reduction can be achieved. Therefore, the burden on the ear of the earphone 9 can be reduced.

  In addition, although the example which made the earphone 9 branch in two directions in FIG. 9 was demonstrated, it is not limited to the branch to two directions. For example, the protrusions 97 can be formed in a plurality of radial shapes. Thereby, a feeling of fitting to an ear can be improved. Furthermore, as shown in the third embodiment, by providing the vent holes 83 in each projecting portion 97, it is possible to provide variations in sound adjustment.
