[0002] A speaker is the most important device in an audio system, which can convert electrical signals into sound signals and transmit them outward. A speaker terminal generally consists of a terminal, a tape, and a connection socket, and the terminal is connected to the tape. With the intensification, miniaturization, and multi-layerization of electronic products, people's demand for the use functions of speakers is increasing day by day, which puts higher requirements on the terminals.

[0003] After retrieval, the Chinese utility model patent with the patent application number CNCN201020182903.3 discloses a terminal of a small speaker, which includes a terminal hole, a connecting plate, a wire fixing plate, a contact elastic piece, a bump, and a positioning plate. An insertion port is provided at the front end of the terminal hole, and the insertion port is square. A contact elastic piece extends upward from the lower side wall surface inside the terminal hole, and a positioning plate extends toward the terminal hole from the end of the upper side wall of the terminal hole. By adopting a square front opening, a male PIN is easy to insert with small resistance; a contact elastic piece is provided, so that the male PIN is easy to insert, and a positioning plate is provided. After the male PIN is inserted, it can be fixed in the correct position, and the connection part between the speaker and the male PIN will not be damaged, and the service life is long.

[0004] Another example is the Chinese utility model patent with the patent application number CN201520613970.9, which discloses a speaker terminal, which consists of a terminal, a wire fixing head, an elastic contact, a fastening socket, a fixing table, a connecting belt, and a clearance step. The terminals are connected in series by the connecting belt for the upper and lower terminals. When the speaker terminal is used, the connecting belt is cut off.

The terminal post, the positive electrode solder tab 4, and the negative electrode solder tab 5 are all mounted on the terminal block 1. The positive electrode solder tab 4 and the negative electrode solder tab 5 are each electrically connected to the terminal post. The first connecting fuse 2 and the second connecting fuse 3 are both inserted at the bottom of the positive electrode solder tab 4 and the negative electrode solder tab 5. It can be understood that the terminal block 1 can be made of hard plastic material, etc., and the terminal post, the positive electrode solder tab 4, and the negative electrode solder tab 5 can all be made of conductive metal material, etc.

[0023] Specifically, the terminal includes a positive terminal 6 and a negative terminal 7, and the positive terminal 6 and the negative terminal 7 are electrically connected to the positive solder tab 6 and the negative solder tab 7 respectively; hanging ears 8 are provided on the positive solder tab 6 and the negative solder tab 7, and the hanging ears 8 are sleeved on the outer side of the upper end of the terminal, and a nut 9 is threadedly connected to the outer side of the upper end of the terminal; inserts 10 are provided at the upper ends of the first connecting fuse 2 and the second fuse 3, and insert through holes 11 for inserting the inserts 10 are formed at the bottoms of the positive solder tab 4 and the negative solder tab 5; elastic pieces 12 are provided on the outer sides of the bottoms of the solder tabs, and the terminal block 1 is provided with solder tab mounting parts 13 adapted to the positive solder tab 4 and the negative solder tab 5, and a plurality of elastic piece through holes 14 adapted to the elastic pieces 12 are formed on the sides of the solder tab mounting parts 13; power cord buckles 15 for connecting power cords are provided on the outer sides of the upper ends of the positive solder tab 4 and the negative solder tab 5.
