Abstract: A microphone comprises a three-pin socket, a first USB socket and a USB adapter. The first USB socket is fixed within the three-pin socket. The three-pin socket comprises an inserted block and three pins. The three pins are fixed on the inserted block. The first USB socket is embedded in the inserted block. The USB adapter comprises a USB plug which matches the first USB socket and a second USB socket which has a different dimension from the first USB socket. The USB plug and the second USB socket are connected electrically. The microphone can be normally used at all occasions. The dimension of the finished product is reduced so as to save a very large space. The microphone can be electrically connected with a USB data line with a USB plug having a different dimension from the first USB socket.

Abstract: An ear hook microphone comprises an ear hook, a cable pole, a cable pole receiving device and a cable pole adjusting device. The ear hook comprises an injection position. The cable pole receiving device is fixed in the injection position and comprises an underlying flange. The cable pole adjusting device is fixed in the cable pole receiving device, which includes a fixed block, a pressing block, a button and a plurality of flexible members. The fixed block includes a base plate. A button hole is formed in the middle of the base plate. Two side plates upwardly extend from the two opposite ends of the base plate respectively. Each of the two side plates opens a through hole at the cable pole. The pressing block is placed between the two side plates. The top end of the button inserts through the button hole then connects with the pressing block. The button comprises a bar. The top end of the bar has a perforated hole. An upborne flange protrudes from the lower portion of the bar.

Abstract: 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. 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.
