Title: Ear-hanging microphone

Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to a microphone, in particular to a microphone that can be carried conveniently, and the position of the microphone can be adjusted, and the microphone is not easy to distort. 
     At present, microphone is an very usual electronic commodity in people&#39;s life. There are many different kinds of microphone products. Headset microphone is very popular, but it is inconvenient to carry and can&#39;t adjust its position according to the shape and size of user&#39;s head. 
     Many ear-hanging microphone is not flexible. After the hanger is worn on a big ear of the first people, the hanger of the ear-hanging microphone is pushed to be so bigger and the shape of the bigger hanger can&#39;t resume. The second people having small ears feels the hanger too loose when he wears the hanger on his ear. This problem disturbs not only usage convenience but also user&#39;s mood. 
     BRIEF SUMMARY OF THE INVENTION 
     The object of the present invention is to provide a microphone, the microphone can be carried conveniently, and the position of the microphone can be adjusted, and the microphone is not easy to distort. 
     The present invention provides an ear-hanging microphone comprising: a c-shaped hanger; a cable pole, whose first end connecting said hanger at a first end thereof; a flexible strap, whose two ends being twisted on said hanger, and the length of said flexible strap being shorter than the longest one of the diameters of said hanger; a microphone, which connecting said cable pole at a second end thereof; a stop block, which connecting said hanger at a second end thereof; a socket, which being embedded in said stop block, and said socket and said microphone being linked electrically; a pin, which being correspondingly inserted into said socket to realize electrical link; and an electrical cable, which being linked electrically with said pin. 
     The ear-hanging microphone has some obvious advantages: small volume, convenient carrying, stable hanging on ear, convenient adjustment of the position. Because of the usage of the flexible strap, the usage period of the ear-hanging microphone is prolonged and the user feels more comfortable and convenienter. 
    
    
     
       BRIEF DESCRIPTION OF THE DRAWINGS 
         FIG. 1  is an assembly drawing of the embodiment of the present invention. 
     
    
    
     DETAILED DESCRIPTION OF THE INVENTION 
     As shown in  FIG. 1 ,  FIG. 1  is an assembly drawing of an ear-hanging microphone being disclosed in the patent. The ear-hanging microphone includes a c-shaped hanger  1 , a cable pole  2 , a flexible strap  3 , a microphone  4 , a stop block  5 , a socket  6 , a pin  7  and an electrical cable  8 . 
     The hanger  1  is worn on an ear of a user&#39;s. The hanger  1  is unenclosed and semicircular, so the hanger  1  produces such a strong force that the hanger  1  nips the ear tightly, and so the hanger  1  keeps hanging on the ear. 
     The cable pole  2  is linear. A first end of the cable pole  2  connects the hanger  1  at a first end thereof. The cable pole  2  and the hanger  1  are integrative in production. 
     The flexible strap  3  is made of a kind of plastic material. Two distal ends of the flexible strap  3  are twisted on the hanger  1 . The length of the flexible strap  3  is shorter than the longest one of the diameters of the hanger  1 . 
     The microphone  4  connects the cable pole  2  at a second end thereof. 
     The stop block  5  connects the hanger  1  at a second end thereof. The stop block  5  presses on the rear portion of the ear while the hanger  1  is being hung on the ear. 
     The socket  6  is embedded in the stop block  5 . The socket  6  and the microphone  4  is linked electrically with some cables (not shown in drawings). There are many inner screw threads (not marked in drawings) inside the socket  6 . 
     The pin  7  comprises many outer screw threads (not marked in drawings) corresponding to the inner screw threads of the socket  6 . The pin  7  inserts into the socket  6  to realize electrical link. And it is much stabler when the outer screw threads and the inner screw threads lock each other. 
     The electrical cable  8  is linked electrically with the pin  7 . 
     By means of the connection of the outer screw threads and the inner screw threads, the electrical cable  8 , the pin  7 , the socket  6  and the microphone  4  are all linked electrically. 
     To use the ear-hanging microphone, firstly, you should hang it on your ear, then you should adjust the positions of the cable pole  2  or the microphone  4  to make the microphone  4  to a suitable position near user&#39;s mouth. Because of flexibility of the hanger  1 , the ear-hanging microphone is hung on the ear stably. The stop block  5  can make the ear-hanging microphone much stabler, moreover, the ear feels more comfortable because of the stop block  5 . The flexible strap  3  can help user renew the hanger  1  much easier. 
     The ear-hanging microphone has many advantages: small volume, convenient carrying. Because of the usage of the flexible strap  3 , the usage period of the ear-hanging microphone is prolonged and the user feels more comfortable and convenienter. Furthermore, when the electrical cable  8  is damaged, we can renew it conveniently, that is to say, the usage period of the ear-hanging microphone is prolonged. The pin  7  connects the socket  6  by the interaction between the outer screw threads and the inner screw threads, so it benefits to avoid the electrical cable  8  falling off.
