Thus, a headphone device that can provide a strong and stable wearing state to anyone with a simple configuration can be realized.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

(1) First Embodiment In FIG. 7, reference numeral 100 denotes a vertical type ear-hook type headphone as a whole according to the first embodiment of the present invention, which is pulled out from the lower end of the vertical type driver unit 101. The connecting cord 102 having a predetermined diameter (for example, 1.6 mm in diameter) has a loop shape that wraps around the outer shape of the ear shell.

  At this time, the earphone 100 is provided with a cylindrical cord holding portion 103 that is integrated with the side surface of the driver unit 101, and a part of the connection cord 102 having a loop shape is part of the cord holding portion 103. Is inserted.

  The connection cord 102 is formed of, for example, a soft thermoplastic elastomer, and fits so as to wrap around the entire earshell and to provide a good wearing feeling.

  The cord holding portion 103 is formed in a substantially inverted C shape such that a tube material having a predetermined diameter (for example, 2.4 mm in diameter) made of, for example, a hard resin material or plastic material follows the outer shape in front of the ear shell. The connecting cord 102, a part of which is inserted into the cylindrical structure, can be slid according to the pulling operation of the user in the direction of the arrow.

  In addition, the material of the cord holding part 103 may be a synthetic resin such as polypropylene (PP) or polyethylene terephthalate (PBP), silicon rubber, vinyl chloride, or the like.

  Incidentally, the cord holding part 103 is formed in a size slightly larger than the diameter 1.6 mm of the connection cord 102 so that the connection cord 102 can be inserted while sliding inside the cylindrical structure. When the connection cord 102 slides inside the cord holding portion 103, a certain amount of friction is generated.

  Thus, in the earphone 100, the connection cord 102 inserted into the cord holding portion 103 is held at that position by friction unless the plug 102D side of the connection cord 102 is pulled from the cord holding portion 103 by the user. Therefore, the size of the loop formed by the connection cord 102 can be maintained.

  Accordingly, the earphone 100 can arbitrarily change the positional relationship between the connection cord 102 and the cord holding portion 103 according to the pulling operation with respect to the connection cord 102 and can hold it at the position at that time. The size of the loop formed by the connection cord 102 can be freely changed.

  Thus, in the earphone 100, the loop formed by the connection cord 102 can be freely changed so that the outer shape of the ear shell is wrapped by the loop of the connection cord 102 regardless of the shape and size of the ear shell. Thus, the connection cord 102 is brought into close contact with each other, and thus an optimal wearing feeling can be always provided to the user.

  In the earphone 100, the connecting cord 102 and the cord holding portion 103 are not held by friction, but the position of the connecting cord 102 with respect to the cord holding portion 103 is not changed. A stopper may be provided.

  Furthermore, the earphone 100 is the first few centimeters of the connection cord 102 drawn from the lower end of the driver unit 101, and the thick cord portion 102A having a substantially U shape along the outer shape of the earlobe is otherwise. The outer diameter is slightly larger than that of the other thin cord portion 102B (that is, the wall thickness is thick), and the thick cord portion 102A and the thin cord portion 102B are integrated by a joining portion 102C having a predetermined length. .

  Specifically, the thin cord portion 102B of the connection cord 102 has a diameter of 1.6 mm, whereas the thick cord portion 102A has a diameter of 2.0 mm. As a result, the connecting cord 102 is so rigid that the thick cord portion 102A along the outer shape of the earlobe can retain its shape, and the other fine cord portion 102B is in relation to the back side root portion of the ear shell. It is designed to maintain the flexibility of being in close contact.

  Thus, when the earphone 100 is worn, the flexible thin cord portion 102B of the connecting cord 102 is in close contact with the backside root portion of the ear shell, and maintains a high fit, while the backside root portion of the earlobe is maintained. The solid thick cord portion 102A that is in close contact with the portion can maintain the shape of the loop along the outer shape of the ear shell by the connecting cord 102.

  Incidentally, if the connecting cord 102 is integrated with the material of the thick cord portion 102A using a material harder than the thin cord portion 102B, it is necessary to make the outer diameter of the thick cord portion 102A larger than the outer diameter of the thin cord portion 102B. No.

  In the above configuration, the earphone 100 is connected to the connection cord 102 against the frictional force between the cord holding portion 103 and the connection cord 102 when the plug 102D side of the connection cord 102 is pulled downward as shown in FIG. When the cord 102 slides inside the cord holding portion 103, the size of the loop formed by the connection cord 102 can be reduced.

  Therefore, in the earphone 100, when the loop of the connection cord 102 is hooked on the user's ear shell and the plug 102D side of the connection cord 102 is pulled downward, the size of the loop by the connection cord 102 is reduced. Thus, the connection cord 102 is in close contact with the ear shell so as to wrap around the entire circumference.

  That is, the earphone 100 can freely adjust the size of the loop formed by the connection cord 102 via the cord holder 103, so it can be worn by anyone regardless of the shape and size of the earshell. The holding state at the time can be strengthened, and the tightening degree (fit feeling) can be freely adjusted.

  In particular, the earphone 100 is configured such that the connection cord 102 slides through the cord holding portion 103 formed in a substantially inverted C shape, so that the loop shape of the connection cord 102 is broken. The connection cord 102 can be closely attached so as to always wrap the ear shell.

  In addition, the earphone 100 can increase the size of the loop when the connection cord 102 is pulled in the reverse direction, so that fine adjustment such as loosening the wearing state can be easily performed.

  In addition, the earphone 100 is a first few centimeters of the connection cord 102 drawn from the lower end of the driver unit 101, and has a thick cord portion 102A having a substantially U shape along the outer shape of the earlobe. The outer diameter is thicker than the other thin cord portion 102B, and it is not only the cord holding portion 103 but also a strong thick cord portion at the time of mounting by holding the rigidity that can hold the shape. The loop shape of the connection cord 102 can also be maintained by 102A, and the connection cord 102 can be brought into close contact so as to wrap the ear shell.

  According to the above configuration, the earphone 100 can form a loop that wraps the earshell by the connection cord 102, and the size of the loop can be adjusted. In addition, a strong and comfortable wearing feeling can be provided to anyone via the loop of the connection cord 102.

(2) Second Embodiment In FIG. 9, in which parts corresponding to those in FIG. 7 are assigned the same reference numerals, 110 indicates a vertical type ear-hook type headphone according to the second embodiment of the present invention as a whole, A connecting cord 102 having a predetermined diameter (for example, a diameter of 1.6 mm) drawn from the lower end of the type driver unit 101 has a loop shape that wraps around the outer shape of the ear shell.

  At this time, the earphone 110 is provided with a tubular cord holding part 113 integrated with the side surface of the driver unit 101, and a part of the connection cord 102 having a loop shape is provided in the cord holding part 113. Is inserted.

  The connection cord 102 is formed of, for example, a soft thermoplastic elastomer, and fits so as to wrap around the entire earshell and to provide a good wearing feeling.

  The cord holding portion 113 is formed by, for example, a substantially inverted C-shaped tube made of a hard resin material or a plastic material having a predetermined diameter (for example, a diameter of 2.4 mm) along the outer shape in front of the ear shell. A cord cover 111 is integrally attached to one end of the cord holding portion 113, for example, made of cloth, and covering a portion of the connection cord 102 corresponding to the upper portion of the ear shell.

  In addition, as a material of the cord holding part 113, a synthetic resin such as polypropylene (PP) or polyethylene terephthalate (PBP), silicon rubber, vinyl chloride, or the like may be used.

  Incidentally, the material of the cord cover 111 is not limited to cloth, and a rubber-based material such as silicon rubber or a resin-based material can be used as long as it can provide a soft wearing feeling to the user.

  Therefore, in the earphone 110, a part of the connection cord 102 is inserted into both the cord cover 111 and the cord holding portion 113, and the cord cover 111 is particularly closely attached above the ear shell when worn. ing.

  Further, in the earphone 110, the connection cord 102, a part of which is inserted into the cylindrical structure of the cord holding portion 113, can be slid according to the pulling operation of the user in the arrow direction.

  Incidentally, the cord holding part 113 is formed in a size slightly larger than the diameter 1.6 mm of the connection cord 102 so that the connection cord 102 can be inserted through the inside of the cylindrical structure while sliding. When the connection cord 102 slides inside the cord holding portion 113, a certain amount of friction is generated.

  As a result, in the earphone 110, unless the user pulls the plug 102D side of the connection cord 102 from the cord holding portion 113, the connection cord 102 inserted into the cord holding portion 113 is held at that position by friction. Therefore, the size of the loop formed by the connection cord 102 can be maintained.

  Therefore, the earphone 110 can arbitrarily change the positional relationship between the connection cord 102 and the cord holding portion 113 according to the pulling operation with respect to the connection cord 102 and can hold it at the position at that time. The size of the loop formed by the connection cord 102 can be freely changed.

  Thus, in the earphone 110, the size of the loop formed by the connection cord 102 is freely changed, so that the outer shape of the earshell is wrapped by the loop of the connection cord 102 regardless of the shape and size of the earshell. Thus, the connection cord 102 is brought into close contact with each other, and thus an optimal wearing feeling can be always provided to the user.

  The earphone 110 does not hold the connection cord 102 and the cord holding portion 113 by friction, but has a predetermined structure so that the position of the connection cord 102 does not change with respect to the cord holding portion 113. A stopper may be provided.

  Further, the earphone 110 is the first few centimeters of the connection cord 102 drawn from the lower end of the driver unit 101, and the thick cord portion 102A having a substantially U shape along the outer shape of the earlobe is otherwise. The outer diameter is slightly larger than that of the other thin cord portion 102B (that is, the wall thickness is thick), and the thick cord portion 102A and the thin cord portion 102B are integrated by a joining portion 102C having a predetermined length. .

  Specifically, the thin cord portion 102B of the connection cord 102 has a diameter of 1.6 mm, whereas the thick cord portion 102A has a diameter of 2.0 mm. As a result, the connecting cord 102 is so rigid that the thick cord portion 102A along the outer shape of the earlobe can retain its shape, and the other fine cord portion 102B is in relation to the back side root portion of the ear shell. It is designed to maintain the flexibility of being in close contact.

  Accordingly, when the earphone 110 is worn, the flexible thin cord portion 102B of the connecting cord 102 is in close contact with the upper root portion of the ear shell via the cord cover 111 and the back side of the ear shell. The flexible thin cord portion 102B of the connecting cord 102 directly adheres to the root portion, thereby maintaining a high fit, while the thick thick cord portion 102A closely contacting the back side root portion of the earlobe, The connection cord 102 can keep the shape of the loop along the outer shape of the ear shell.

  Incidentally, if the connecting cord 102 is integrated with the material of the thick cord portion 102A using a material harder than the thin cord portion 102B, it is necessary to make the outer diameter of the thick cord portion 102A larger than the outer diameter of the thin cord portion 102B. No.

  In the above configuration, as shown in FIG. 10, the earphone 110 is connected to the connection cord 102 against the frictional force between the cord holding portion 113 and the connection cord 102 when the plug 102D side of the connection cord 102 is pulled downward. When the cord 102 slides inside the cord holding portion 113, the size of the loop formed by the connection cord 102 is reduced.

  Therefore, in the earphone 110, when the loop of the connection cord 102 is hooked on the user's ear shell, when the plug 102D side of the connection cord 102 is pulled downward, the size of the loop by the connection cord 102 is reduced. Thus, the connection cord 102 is in close contact with the ear shell so as to wrap around the entire circumference.

  At this time, in the earphone 110, as the size of the loop by the connection cord 102 becomes smaller, the connection cord 102 does not directly adhere to the back side root portion above the ear shell, but a cord cover Since 111 sticks to the back side root portion above the ear shell, it is possible to provide the user with a more comfortable wearing feeling than the connection cord 102 sticks directly.

  As described above, the earphone 110 can freely adjust the size of the loop formed by the connection cord 102 via the cord holding portion 113. In addition, the holding state at the time of wearing can be strengthened and the tightening degree (fit feeling) can be freely adjusted.

  In particular, the earphone 110 is configured such that the connection cord 102 slides through the cord holding portion 113 formed in a substantially inverted C shape, so that the loop shape of the connection cord 102 is broken. The connection cord 102 can be closely attached so as to always wrap the ear shell.

  In addition, the earphone 110 can increase the size of the loop when the connection cord 102 is pulled in the opposite direction, so that fine adjustment such as loosening the wearing state can be easily performed.

  Note that the earphone 110 is the first few centimeters of the connection cord 102 drawn from the lower end of the driver unit 101, and has a thick cord portion 102A having a substantially U shape along the outer shape of the earlobe. The outer diameter is thicker than the other thin cord portion 102B, and it is not only the cord holding portion 113 but also a strong thick cord portion at the time of mounting by holding the rigidity that can hold the shape. The connection cord 102 can also be brought into close contact with the connection cord 102 so that the loop shape of the connection cord 102 can be maintained by 102A and the ear shell is wrapped.

  According to the above configuration, the earphone 110 can form a loop that wraps the earshell by the connection cord 102, and has a structure in which the size can be adjusted. Regardless of the size, a strong and comfortable wearing feeling can be provided to anyone through the loop of the connection cord 102.

(3) Third Embodiment In FIG. 11, in which parts corresponding to those in FIG. 7 are assigned the same reference numerals, 120 indicates a vertical type ear-hook type headphone according to a third embodiment of the present invention as a whole. A connection cord 122 having a predetermined diameter (for example, a diameter of 1.6 mm) drawn from the lower end of the type driver unit 101 has a loop shape that wraps around the outer shape of the ear shell.

  The earphone 120 is also provided with a cylindrical cord holding portion 123 that is integrated with the side surface of the driver unit 101, and a part of the connection cord 122 depicting a loop shape is the cord holding portion 123. Is inserted.

  The connection cord 122 is made of, for example, a soft thermoplastic elastomer, and fits so as to wrap around the entire earshell along the outer shape of the earshell, and can provide a good wearing feeling.

  The cord holding portion 123 is formed by a tube material having a predetermined diameter (for example, a diameter of 2.4 mm) made of, for example, a hard plastic material, and is formed in a substantially inverted S shape along the outer shape in front of the ear shell and the earlobe portion. The connecting cord 122, a part of which is inserted into the cylindrical structure, can be slid according to the pulling operation of the user in the direction of the arrow.

  In addition, as a material of the cord holding part 123, synthetic resin such as polypropylene (PP) or polyethylene terephthalate (PBP), silicon rubber, vinyl chloride, or the like may be used.

  Incidentally, the inner diameter of the cord holding portion 123 is slightly larger than the diameter of 1.6 mm of the connection cord 122 so that the connection cord 122 can be inserted through the cylindrical structure while sliding. When the connection cord 122 slides inside the cord holding portion 123, a certain amount of friction is generated.

  Thus, in the earphone 120, unless the user pulls the plug 122D side of the connection cord 122 from the cord holding portion 123, the connection cord 122 inserted into the cord holding portion 123 is held at that position by friction. Therefore, the size of the loop formed by the connection cord 122 can be maintained.

  Therefore, the earphone 120 can arbitrarily change the positional relationship between the connection cord 122 and the cord holding portion 123 according to the pulling operation with respect to the connection cord 122 and can hold it at the position at that time. The size of the loop formed by the connection cord 122 can be freely changed.

  Thus, in the earphone 120, the size of the loop formed by the connection cord 122 is freely changed, so that the outer shape of the ear shell is wrapped by the loop of the connection cord 122 regardless of the shape and size of the ear shell. Thus, the connection cord 122 is brought into close contact with each other, and thus an optimal wearing feeling can be always provided to the user.

  The earphone 120 does not hold the connection cord 122 and the cord holding portion 123 by friction, but has a predetermined structure so that the position of the connection cord 122 does not change with respect to the cord holding portion 123. A stopper may be provided.

  Incidentally, in the earphone 120, unlike the connection cord 102 of the earphone 100 in the first embodiment, the outer diameters of the connection cords 122 are all uniform. The connecting cord 122 is arranged along the outer shape of the earlobe through the portion 123A.

  As a result, when the earphone 120 is worn, the connection cord 122 is in close contact with the backside root portion of the ear shell, and the earlobe portion 123A of the cord holding portion 123 is in close contact with the backside root portion of the earlobe, The connection cord 122 and the cord holding portion 123 can hold the loop shape that wraps the ear shell.

  Further, since the earphone 120 is configured to discharge the connection cord 122 inserted through the inside of the earlobe portion 123A of the cord holding portion 123, the connection cord 122 is located behind the earlobe, The troublesomeness caused by the connection cord 122 coming into contact with the user's cheek can be avoided.

  In the above configuration, as shown in FIG. 12, the earphone 120 is connected to the cord 122 when the plug 122D side of the connection cord 122 is pulled downward against the friction force between the cord holding portion 123 and the connection cord 122. When the cord 122 slides inside the cord holding portion 123, the size of the loop formed by the connection cord 122 is reduced.

  Therefore, in the earphone 120, when the loop of the connection cord 122 is hooked on the user's ear shell, when the plug 122D side of the connection cord 122 is pulled downward, the size of the loop by the connection cord 122 is reduced. Thus, the connection cord 122 is in close contact with the ear shell so as to wrap around the entire circumference.

  In other words, the earphone 120 can freely adjust the size of the loop formed by the connection cord 122 via the cord holder 123, so it can be worn by anyone regardless of the shape and size of the earshell. The holding state at the time can be strengthened, and the tightening degree (fit feeling) can be freely adjusted.

  In particular, the earphone 120 is configured such that the connection cord 122 slides through the cord holding portion 123 formed in a substantially inverted S shape, so that the loop shape of the connection cord 122 is broken. The connection cord 122 can be closely attached so as to always wrap the ear shell.

  In addition, the earphone 120 is configured such that the connecting cord 122 extends along the outer shape of the earlobe through the cord holding portion 123 by the earlobe portion 123A of the cord holding portion 123. The connection cord 122 is brought into close contact with the portion, and the earlobe portion 123A of the cord holding portion 123 is positioned at the back side root portion of the earlobe.

  Thus, even when the connection cord 122 is pulled, the earphone 120 can maintain the shape of the loop that is adapted to follow the outer shape of the earlobe by the earlobe portion 123A of the cord holding portion 123, and always wraps the earshell. Thus, the connection cord 122 can be brought into close contact.

  Note that the earphone 120 can increase the size of the loop when the connection cord 122 is pulled in the opposite direction, so that fine adjustments such as loosening the wearing state can be easily performed.

  According to the above configuration, the earphone 120 can form a loop that wraps the earshell by the connection cord 122 and has a structure that can be adjusted in size. Regardless of the size, a strong and comfortable wearing feeling can be provided to anyone through the loop of the connection cord 122.

  Accordingly, the earphone 130 can arbitrarily change the positional relationship between the connection cord 122 and the cord holding portion 133 according to the pulling operation with respect to the connection cord 122, and can hold it at the position at that time. The size of the loop formed by the connection cord 122 can be freely changed.

  Thus, in the earphone 130, the size of the loop formed by the connection cord 122 can be freely changed by the cord holding portion 133, so that the loop of the connection cord 122 can be performed regardless of the shape and size of the earshell. Thus, the connection cord 122 is brought into close contact with the back side root portion of the ear shell while enveloping the ear shell, so that an optimal wearing feeling can be always provided to the user.

  In the above configuration, as shown in FIG. 15, the earphone 130 is configured such that when the plug 122D side of the connection cord 122 is pulled downward, the connection cord 122 slides while being sandwiched between the cord holding portions 133. The size of the loop formed by the connection cord 122 is reduced.

  Therefore, in the earphone 130, when the loop of the connection cord 122 is hooked on the user's ear shell, when the plug 122D side of the connection cord 122 is pulled downward, the size of the loop by the connection cord 122 is reduced. Thus, the connection cord 122 is in close contact with the ear shell so as to wrap around the entire circumference.

  In this way, the earphone 130 can freely adjust the size of the loop formed by the connection cord 122 via the cord holding portion 133, so that no matter who the shape and size of the earshell, In addition, the holding state at the time of wearing can be strengthened and the tightening degree (fit feeling) can be freely adjusted.

  Note that the earphone 130 can increase the size of the loop when the connection cord 122 is pulled in the opposite direction, so that fine adjustment such as loosening the wearing state can be easily performed.

  Further, in the earphone 130, as shown in FIG. 16, when the connection cord 122 is removed from the state of being sandwiched by the cord holding portion 133 and released, the connection cord 122 hangs down by its own weight. As a result, the loop formed by the connection cord 122 disappears.

  Therefore, when it is not necessary to attach the earphone 130 to the ear shell via a loop formed by the connection cord 122, the earphone 130 is released from the state in which the earphone is sandwiched between the cord holders 133. There can be no change to use as a general headphone.

  As described above, the earphone 130 is used as an earphone only by allowing the user to select whether the connection cord 122 is held between the cord holder 133 or the cord holder 133 and is released from the cord holder 133. Or use as general headphones can be switched instantaneously.

  At this time, the earphone 140 is provided with a cord holding portion 133 formed of two rectangular parallelepiped projections integrated with the side surface of the driver unit 101, and a part of the connection cord 102 depicting a loop shape. Is attached in a state of being fitted into the cord holding portion 133.

  The connection cord 102 is formed of, for example, a soft thermoplastic elastomer, and fits so as to wrap around the entire earshell and to provide a good wearing feeling.

  Incidentally, the cord holding unit 133 has the same configuration as that of the earphone 130 in the fourth embodiment, and the description thereof is omitted here for convenience.

  Therefore, in the earphone 140, when the connection cord 102 is pushed between the projections 133A and 133B, the connection cord 102 is sandwiched in the respective recesses formed on the inward surfaces of the projections 133A and 133B, and The connection cord 102 is sandwiched and held at the position by the elastic force of the projections 133A and 133B.

  That is, in the earphones 140, when the connection cord 102 is pulled in the direction of the arrow by the user, the connection cord 102 can be slid while the connection cord 102 is sandwiched between the cord holding portions 133.

  As a result, in the earphone 140, the connection cord 102 held between the cord holding portions 133 is held at that position unless the user pulls the plug 102D side of the connection cord 102 while being held between the cord holding portions 133. Therefore, the size of the loop formed by the connection cord 102 can be maintained.

  Therefore, the earphone 140 can arbitrarily change the positional relationship between the connection cord 102 and the cord holding portion 133 according to the pulling operation with respect to the connection cord 102 and can hold it at the position at that time. The size of the loop formed by the connection cord 102 can be freely changed.

  Thus, in the earphones 140, the size of the loop formed by the connection cord 102 can be freely changed, so that the earshell is wrapped in the loop of the connection cord 102 regardless of the shape and size of the earshell. The connection cord 102 is brought into close contact with the back side root portion of the ear shell, so that an optimal wearing feeling can always be provided to the user.

  The earphone 140 is the first few centimeters of the connection cord 102 drawn from the lower end of the driver unit 101, and the thick cord portion 102A having a substantially U shape along the outer shape of the earlobe is otherwise.

  Specifically, the thin cord portion 102B of the connecting cord 102 has a diameter of 1.6 mm, whereas the thick cord portion 102A has a diameter of 2.0 mm. As a result, the connecting cord 102 is so rigid that the thick cord portion 102A along the outer shape of the earlobe can retain its shape, and the other fine cord portion 102B is in relation to the back side root portion of the ear shell. It is designed to maintain the flexibility of being in close contact.

  As a result, the earphone 140 keeps a high fit when the earphones 140 are attached to the upper base portion and the back base portion of the ear shell by the thin cord portion 102B having flexibility in the connecting cord 102. On the other hand, the rigid thick cord portion 102A that is in close contact with the back side root portion of the earlobe can hold the loop shape along the outer shape of the ear shell by the connecting cord 102.

  Incidentally, if the connecting cord 102 is integrated with the material of the thick cord portion 102A using a material harder than the thin cord portion 102B, it is necessary to make the outer diameter of the thick cord portion 102A larger than the outer diameter of the thin cord portion 102B. No.

  In the above configuration, as shown in FIG. 18, in the earphone 140, when the plug 102D side of the connection cord 102 is pulled downward, the connection cord 102 slides while being sandwiched between the cord holding portions 133. The size of the loop formed by the connection cord 102 is reduced.

  Therefore, in the earphone 140, when the plug 102D side of the connection cord 102 is pulled downward in a state where the loop of the connection cord 102 is hooked on the user's ear shell, the size of the loop by the connection cord 102 is reduced. Thus, the connection cord 102 is in close contact with the ear shell so as to wrap around the entire circumference.

  As described above, the earphone 140 can freely adjust the size of the loop formed by the connection cord 102 via the cord holding portion 133. In addition, the holding state at the time of wearing can be strengthened and the tightening degree (fit feeling) can be freely adjusted.

  Note that the earphone 140 can increase the size of the loop when the connection cord 102 is pulled in the opposite direction, so that fine adjustments such as loosening the wearing state can be easily performed.

  In addition, in the earphone 140, as shown in FIG. 19, when the connection cord 102 is removed from the state where it is sandwiched by the cord holding portion 133 and released, the connection cord 102 hangs down by its own weight, so that the connection cord 102 The loop formed by the code 102 disappears.

  Therefore, when it is no longer necessary to attach the earphone 140 to the ear shell through the loop of the connection cord 102, the earphone can be used by opening the connection cord 102 from a state of being sandwiched between the cord holders 133. There can be no change to use as a general headphone.

  As described above, the earphone 140 is used as an earphone only by allowing the user to select whether to hold the connection cord 102 between the cord holders 133 or to release the cords from the cord holder 133. Or use as general headphones can be switched instantaneously.

  However, even when the loop formed by the connection cord 102 is extinguished, the ear-mounted headphone 140 retains the rigidity that can retain the shape of the thick cord portion 102A. Only the thin cord portion 102B after the joining portion 102C hangs down, and the troublesomeness caused by the connection cord 102 coming into contact with the cheek of the user can be avoided.

  According to the above configuration, the ear-mounted headphone 140 can form a loop that wraps the ear shell with the connection cord 102 and has a structure that can be adjusted in size. Regardless of the size, a strong and comfortable wearing feeling can be provided to anyone via the loop of the connection cord 102.
