     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a headphone device, and is suitably applied to an ear-hook type headphone device that is used by being connected to, for example, a portable music player. 
     2. Description of the Related Art 
     As shown in  FIG. 1 , there has heretofore been an ear-hook type headphone device  100  that is worn in such a manner as hooking a hanger section  101  having an arm shape on ear capsules (for example, refer to Jpn. Pat. Appln. Laid-Open Publication No. 2003-143680). 
     SUMMARY OF THE INVENTION 
     In the ear-hook type headphone device  100  having the above configuration, the hanger section  101  needs to be hardened so that the hanger section  101  is held firmly on a head. However, in such a case, there has been a problem that hardening the hanger section  101  itself causes a worse feeling of wearing. 
     In addition, in the ear-hook type headphone device  100  having the above configuration, the hanger section  101  is held by an upper section of ear capsules. Accordingly, there has been a problem that a strong impact from the outside causes bending of the hanger section  101 , and in some cases, dropping off of the entire ear-hook type headphone device  100  from ear capsules. 
     Further, in case the ear-hook type headphone device  100  having the above configuration is used by the user while running, there has been a problem that the hanger section  101  comes off from ear capsules due to swinging of running, and the entire ear-hook type headphone device  100  drops off. 
     The present invention has been made in view of the above points, and suggests an ear-hook type headphone device excellent in a feeling of wearing and stability when the headphone device is worn, as compared with the conventional headphone device. 
     In view of the above, according to an aspect of the present invention, there is provided a headphone device that includes a driver unit, and an ear-hook hanger of a loop shape that is integrated with the driver unit and supports an entire circumference of an ear capsule. In this manner, the entire circumference of the ear capsule can be supported by a surface of the ear-hook hanger. Accordingly, stability when the headphone device is worn is further improved, and at the same time, a feeling of fit is also further improved.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Hereinafter, an embodiment of the present invention will be described in detail with respect to the accompanying drawings. 
     (1) Configuration of Ear-Hook Type Headphone Device 
     According to Embodiment of Present Invention  FIGS. 2A and 2B  show an entire ear-hook type headphone device  1  according to an embodiment of the present invention. The ear-hook type headphone device  1  includes an ear-hook hanger  2  and a tubular housing  3 . The ear-hook hanger  2  has a loop shape that is curved along an outer shape of an ear capsule of the user. The tubular housing  3  has a substantially reversed C-shape and is formed around a center section of the ear-hook hanger  2 . 
     The housing  3  is provided with a driver unit  4  around a center thereof. The driver unit  4  is allocated so as to face an eardrum when the driver unit  4  is fit into an external acoustic meatus. 
     The ear-hook hanger  2  is made of an elastic body of synthetic resin, such as polypropylene (PP) and polybutylene terephthalate (PBP). The ear-hook hanger  2  is formed in a curved shape along an outer shape of an ear capsule of a human being, and has a closed annular loop shape as an entire shape. 
     In addition, the ear-hook hanger  2  ( FIG. 2A ) includes a rear arm section  2 B that is not allocated with the housing  3  in contrast to a front arm section  2 A allocated with the housing  3 . 
     The rear arm section  2 B is twisted so as to be positioned closer to an ear capsule. In this manner, especially the entire rear arm section  2 B contacts a backside base section of an ear capsule when the ear-hook hanger  2  is worn. 
     That is, when the ear-hook hanger  2  is worn, a surface of the entire rear arm section  2 B contacts a backside base section of an ear capsule. In this manner, a feeling of wearing and stability when the headphone is worn can be further improved. 
     In addition, the ear-hook hanger  2  includes a protrusion section  5  that projects to a lower backside of an ear capsule formed at a lower section of the rear arm section  2 B. A headphone cord  6  is attached to the ear-hook hanger  2  through the protrusion section  5 . 
     In the above manner, as shown in  FIG. 3 , when the ear-hook hanger  2  is worn, the surface of the entire rear arm section  2 B contacts an ear capsule backside base section ER 2  of an ear capsule ER 1  so that the ear-hook hanger  2  is held by the ear capsule ER 1 . At the same time, the protrusion section  5  fits a hollow at the backside of an ear lobe. Accordingly, a feeling of wearing and stability when the headphone is worn can be further improved. 
     The ear-hook hanger  2  has a knot allocated in an internal space of the protrusion section  5 , so as to avoid pulling out of the headphone cord  6 . Accordingly, size of the protrusion section  5  is utilized for storage space for the knot, instead of providing space for the knot separately. 
     (2) Operation and Advantageous Effect 
     In the structure described above, when the ear-hook type headphone device  1  is actually worn on a head of the user, the ear-hook hanger  2  of a loop shape is put on in a manner hooking on an entire ear capsule, and at the same time, the driver unit  4  fits into an external acoustic meatus. 
     At this time, the ear-hook type headphone device  1  is firmly held with respect to the entire ear capsule ER 1  in such a manner that the driver unit  4  fits into an external acoustic meatus, the surface of the entire rear arm section  2 B of the ear-hook hanger  2  contacts the backside base section ER 2  of the ear capsule ER 1 , and at the same time, the protrusion section  5  fits a hollow at the backside of an ear lobe. 
     In particular, the ear-hook type headphone device  1  has the ear-hook hanger  2  that is formed by an elastic material. Accordingly, individual differences in ear capsules of users are absorbed by such elasticity, and an excellent feeling of wearing can be provided to anyone. 
     In addition, the ear-hook type headphone device  1  includes the ear-hook hanger  2  having a closed loop shape. Accordingly, even in case a strong impact is applied from the outside, a bending amount of the ear-hook hanger  2  is restricted, and the risk that the ear-hook hanger  2  drops off the ear capsule ER 1  can be significantly reduced. 
     Even when the user uses the ear-hook type headphone device  1  while running, the ear-hook hanger  2  does not come off from an ear capsule due to swinging of running. Accordingly, the entire ear-hook type headphone device  1  does not drop off, allowing the user to continue running comfortably. 
     Further, the ear-hook type headphone device  1  includes the headphone cord  6  extending in a backward direction from the protrusion section  5  provided on the rear arm section  2 B of the ear-hook hanger  2 . Accordingly, the user does not feel uncomfortable by the headphone cord  6  hitting a cheek and so on, and an excellent feeling of wearing can be provided. 
     The ear-hook type headphone device  1  does not require a headband. By using the ear-hook hanger  2 , a firm stability when the headphone device is worn that is similar to when a headband is used can be obtained. Accordingly, an excellent feeling of wearing and high stability when the headphone device is worn can be provided with light weight without making the user feel weight of the ear-hook type headphone device  1 . 
     According to the configurations described above, when the ear-hook hanger  2  of a loop shape is mounted in such a manner as hooking the entire ear capsule ER 1 , the ear-hook type headphone device  1  can be mounted firmly on the ear capsule ER 1  by the surface of the entire rear arm section  2 B of the ear-hook hanger  2  contacting the ear capsule backside base section ER 2  of the ear capsule ER 1 .
