Description

Speaker designed for the convenience of tinsel wire connection {A speaker designed for the convenience of tinsel wire connection}

The present invention relates to a speaker, and more particularly, one side of a tinsel wire is soldered to a voice coil and the other end is fixed by soldering by contacting a stopper while the other side is inserted and fixed to a terminal board, thereby discarding without a shaping jig for fixing the tinsel wire It relates to a speaker that promotes the convenience of connection of tinsel wire, which enables reduction of man-hours and length of tinsel wire by eliminating tinsel wire.

A speaker is an acoustic device that converts electrical signals into vibrations of a diaphragm and generates small dense waves in the air to radiate sound waves.

A typical speaker includes a frame, a magnetic circuit part installed on the frame and generating a magnetic force, and a sound generator having a diaphragm installed on the frame and reproducing sound while vibrating by interacting with the magnetic circuit part.

The magnetic circuit unit includes a yoke coupled to the frame, a magnet, a voice coil, and a damper sequentially stacked inside the yoke.

A terminal board to which an external power source is connected is coupled to the outer surface of the frame, and a tinsel wire connected to the voice coil of the diaphragm is connected to the terminal board.

In general, in a method of connecting a tinsel wire to a terminal board installed on a frame of a speaker, one end side of the tinsel wire is connected to the voice coil side, and the other end side is pulled out to the side of the terminal board coupled to one side of the outer surface of the frame.

After setting the length of the tinsel wire using a jig or the like, the other side of the tinsel wire is soldered to the terminal board.

Thereafter, a portion of the unnecessary tinsel wire exposed to the outside of the terminal board is cut.

Since the frame and the terminal board are made of metal, an insulating plate is interposed between the frame and the terminal board to insulate the frame and the terminal board.

The conventional speaker as described above requires a process of cutting the portion of the tinsel wire exposed to the outside of the terminal board, which adds work time and increases the cost because the cut portion of the tinsel wire is discarded.

In addition, it is inconvenient to set the length of the tinsel wire during the process of soldering the tinsel wire, and there are problems such as flow of the tinsel wire during soldering, waste of the tinsel wire, and existence of an additional jig.

In addition, in the conventional manufacturing process, after soldering the tinsel wire to the back of the frame, turning the frame over to the surface and combining the diaphragm, the process of overturning the frame must be performed additionally, which is a cumbersome problem in the manufacturing process due to the addition of the process there was
