     [0013] Please refer to FIG. 1, which is an explosive illustration for the three-dimensional structure of a preferable embodiment of the matching-up of assembly between an earphone and the hanging hook device of earphone of the invention. The earphone  1  is structured as a shape of water drop and may be abutted against one external ear of human body (not shown in the figure). By arranging an amplifier  12  corresponding to the external ear, a sound signal may be provided. The abutting side of the earphone  1  has at least one groove  11  shaped as an arc, with which a pivoting-and-fixing part  2  is connected. The pivoting-and-fixing part  2  is at least arranged with a plurality of fixation seats  22 , a pivoting axis  23 , and at least one elastic element  24 . The fixation seat  22  is connected integrally with the groove  11  as one body, while there is one penetration hole  21  that is arranged at an appropriate position of the center of fixation seat  22  and is made as a circular shape. The pivoting axis  23  first passes through the penetration hole  21 , then penetrates into the elastic element  24 , and again passes through another penetration hole  21 , such that two sides of the pivoting axis  23  are respectively protruded out the fixation seat  22  for facilitating a connection to a hanging hook device of earphone  3 , so a earphone device available for being carried along and being hanged at the external ear of human body is created. In the preferable embodiment of the invention, the number of the fixation seat  22  is two and, of course, it may also be three or more. The pivoting axis  23  matched with the penetration hole  21  is structured as a cylinder shape. The number of the elastic element  24  is at least one, and it is arranged between two adjacent fixation seats  22 . If, when the number of the fixation seat  22  is three, then the number of the elastic element  24  is two. Such kind of variation of number is not described repetitiously herein any more, because above embodiment is belonged to the prior arts and is not the technical characteristic of the invention and, therefore, a detailed description is not presented hereinafter.  
     [0014] Please refer to FIG. 2, which is an illustration of the three-dimensional structure of a preferable embodiment of the hanging hook of earphone of the invention. The hanging hook device of earphone  3  of the invention is comprised of a hanging hook of arm  31  and a pivoting part. The hanging hook of arm  31  may be provided for being hanged at the outer edge of human body, and the abutting side of the hanging hook of arm  31  at the external ear is designed as a structure of multiple-arc shape and is suitable for the ergonomics to be able to be hanged comfortably at the outer ear. In the meantime, the pivoting part  32  is connected to one end of the hanging hook of arm  31 .  
     [0015] Moreover, the pivoting part  32  may be provided for a connection to the pivoting-and fixing part  2 , and is at least arranged with two pivoting seats  321 , a plurality of trough ditches  323 , and at least one positioning part  324 . In the preferable embodiment of the invention, the pivoting seats  321  are respectively arranged at two sides of the pivoting part  32 , and the material of the pivoting seat  321  is plastic or other composite material comprising an elastic device, so it can make a deformation motion of elasticity in appropriate angle. At an appropriate position in the interior of the pivoting seat  321 , there is arranged with an opening hole  322 , which may be provided for one end of the pivoting axis  23  to be placed into and connected with. In the preferable embodiment of the invention, the pivoting seat  321  has an appropriate thickness, and the opening hole  322  is kept an appropriate distance with one end of the pivoting seat  321 . Of course, when the thickness of the pivoting seat  321  is thinner, the opening hole  322  may be also designed as a hole penetrating through the pivoting seat  321 . This kind of design will not influence the deformation motion of elasticity of the pivoting seat  321 . Such kind of variation of design can be implemented by those who are familiar with such kind of arts according to above disclosure, but it still possesses the merits of the invention, and it is also within the spirit and scope of the invention, so a detailed description is not presented repetitiously herein any further. The number and the position of the trough ditch  323  are arranged corresponding to the fixation seat  22  for facilitating the fixation seat  22  to be inset into and connected with the trough ditch  323 .

Further, by arranging an accommodation trough  326  between two opening troughs  325 , it may be provided for the elastic element  24  to be placed in.  
     [0016] When the hanging hook device of earphone  3  is assembled with the earphone  1 , an appropriate force is applied on the hanging hook device of earphone  3  so that, by making a deformation motion of elasticity to the pivoting seat  321  with appropriate angle, it may make two sides of the pivoting axis  23  insets into the opening hole  322  respectively. Since these devices of pivoting seats  321  are operated within their deformation zones of elasticity and the plastic deformation is not reached, so they will not be damaged or generated any permanent deformation and can be used repetitiously. The fixation seat  22  is also inset into and connected with the trough ditch  323 . By applying the opening trough  325  to be provided for a connection and fixation to the pivoting axis  23 , it may create an assembly state of a three-dimensional structure of a preferable embodiment between the earphone and the hanging hook device of earphone of the invention as shown in FIG. 3 and, an earphone device available for being carried along and being hanged at the external ear of human body for application has been formed. In sum, the hanging hook device of earphone according to the present invention may indeed reach the functions exiting in original earphone, further reduces the complexity of assembly, and lowers down the labor time and cost of production. The shortcomings of the prior arts are really overcome, the requests of the industrial production are fulfilled, and their abilities of manufacturing competition are also enhanced.
