     DETAILED DESCRIPTION OF THE INVENTION 
     Referring to  FIGS. 1 ,  2 ,  3  and  4 , a decorative wireless earphone device according to the present invention is a wireless earphone with function of decoration and the first embodiment thereof includes: 
     a necklace  1 , which is made of leather string, with a first end  11  and a second end  12 ; 
     a joining set  2 , which further includes a first joining member  21  attached to the first end  11  of the necklace  1  and a second joining member  22  attached to the second end of the necklace  1  for the necklace  1  being capable of being hung on the neck of the user while the first joining member  21  engaging with the second member  22 ; 
     a microphone  3 , which is joined to the second joining member  22  for voice signal being output by the user; 
     a main unit  4 , which is employed to send/receive wireless signal, such as Bluetooth wireless signal and further includes an ornamental part  41 , an earplug  42 , volume control keys  43 ,  44 , a switch key  45  and an indicating light  46 , wherein the ornamental part  41  has a first surface  411  and a second surface  412  and the first surface  411  is made of jewelry material with design similar to a pendant; the earplug  42  extends outward from the second surface  412  and hides behind the decorative part  41  so that the earplug is invisible from the front side of the first surface  411 ; the indicating light  46  is lighted up if the main unit  4  is in a state of “On”; and the second surface  412  has a third joining member  47  for being joined to the necklace  1 ; 
     an ear receiver  48 , which is associated with the main unit  4  to be disposed at the inner side of the earplug  42 ; and 
     a lead wire  5 , which is disposed in the necklace and electrically connected to the microphone  3  and the main unit  4  with two ends thereof respectively; 
     wherein the distance between the microphone  3  and the ear receiver  48  is about the distance between the mouth and the ear of the user. 
     Referring to  FIGS. 5 and 6 , the first embodiment of the wireless earphone device of the present invention can be implemented such as a blue tooth earphone in which the necklace  1 , the microphone  3 , the main unit  4  and the ear receiver  48  are integrated as a single piece with design of decoration. The main unit  4  provides an appearance like an earring and the earplug  42  hides behind the ornamental part  41  while not in use. The lead wire  5  is invisible in the necklace  1  as shown in  FIG. 5 . The user  6  wearing the wireless earphone looks like wearing a necklace with an earring without a cold feeling of wearing a technological product, the Bluetooth earphone. When the wireless earphone is in use, the only thing has to be done is to insert the earplug  42  into the auditory canal of the ear and the microphone  3  is capable of approaching the mouth simultaneously as shown in  FIG. 6 . Hence, the user  6  is capable of listening to voice with the ear receiver  48  and sending out vocal message. 
     Referring to  FIG. 7 , the engagement of the first joining member  21  to the second joining member  22  is similar to the conventional coaxial cable with the engagement of the male adapter to the female adapter. For instance, the first joining member  21  provides external screw threads  211  and the second joining member  22  has a turnable sleeve  221  with internal screw threads corresponding to the external screw threads  211 . Hence, once the internal threads of the sleeve  221  engage with the external threads of the first joining member  21 , the first joining member  21  is attached to the second joining member  22  firmly. 
     Referring to  FIGS. 8 and 9 , the second embodiment of the decorative wireless earphone device according to the present invention includes a necklace  7 , a joining set  8 , a microphone  9 , a main unit  4 , an ear receiver and a lead wire  5 . The differences of the second embodiment from the first embodiment is in that the necklace  7  is composed of a plurality of balls connecting with each other in series as a string and the first and second joining members  81 ,  82  are different from those used in the first embodiment. The first and second joining members  81 ,  82  have a first ring  811  and the second ring  821  respectively and the second ring  821  has a movable elastic member  822 . When the user exerts a force to the movable end of the movable member  822 , the second ring  821  creates a clearance for engaging with the first ring  811 . In this way, the first and second rings  811 ,  821  can be joined to each other. 
     It is noted that the present invention has combined the second type Bluetooth earphone, which is earplug type earphone, and the fourth type Bluetooth earphone, which is hanging type, such that the wireless earphone device of the present invention has the advantages such as being portable easily and conveniently and overcome the deficiencies of the two types Bluetooth earphone. For instance, if the earplug type Bluetooth earphone is made lighter, thinner, shorter and smaller in order to improve portability and convenience thereof, the microphone with the receiver main unit becomes closer to the ear to affect quality of the received sound unfortunately. The earphone of the present invention is capable of allowing the earpiece being apart a distance from the microphone. In case of the earplug being inserted into the ear, the microphone moves near the mouth automatically to enhance function of the microphone. In addition, the microphone being close to the mouth provides better effect of sound receiving and convenience while in use. 
     It is appreciated that the decorative wireless earphone according to the present invention has overcome the deficiencies of the Bluetooth earphone being incapable of receiving sound easily although the Bluetooth earphone is made with small size. Further, the decorative wireless earphone of the present invention is loved by the female consumers due to the appearance of the earphone being ornamentally designed as a kind of precious article such that it could be hung on the neck naturally and reasonably and chance of being lost becomes less in addition to convenience and easy-storage. Hence, the decorative wireless earphone of the present invention has enhanced the value thereof additionally and competition of product is promoted substantively. 
     While the invention has been described with referencing to preferred embodiments thereof, it is to be understood that modifications or variations may be easily made without departing from the spirit of this invention, which is defined by the appended claims.
