[0034] Among them, the two terminal positioning posts 13 can move relative to each other under the drive of the two positioning and adjusting rods 12, approaching or separating from each other, so as to adjust the distance. Optionally, the heights of the two terminal positioning posts 13 are equal.

[0035] In some optional embodiments, the moving direction of the movable baffle 14 is substantially perpendicular to the moving direction of the positioning and adjusting rod 12, that is, one can be in the front-back direction and the other can be in the left-right direction.

[0036] In some alternative embodiments, track grooves 111 pointing to the opposite sides are respectively formed on the first side and the second side of the support base 11. The track groove 111 includes an opening part and a long groove part. The long groove part communicates with the opening part and the upper surface of the support base 11. The positioning and adjusting rod 12 is inserted into the opening part of the track groove 111 and can move back and forth within the opening part. The terminal positioning post 13 falls into the long groove part and can move back and forth within the long groove part along with the movement of the positioning and adjusting rod 12, and the upper end of the terminal positioning post 13 extends above the long groove part.

[0037] In some alternative embodiments, mounting holes are formed in the positioning and adjusting rod 12, and the lower end of the terminal positioning post 13 is inserted into the mounting hole in a tightly fitting manner.

[0038] In some alternative embodiments, two fixing screw holes 112 are formed on the fourth side of the support base 11. The fourth side is opposite to the third side. The two fixing screw holes 112 respectively communicate with the opening parts of the two track grooves 111. Locking screws (not shown in the figure) are provided in the fixing screw holes 112, and the locking screws are used to fix the terminal adjusting rod 13 at a certain position within the track groove by means of locking and abutting.

[0039] As above, through the two positioning and adjusting rods 12, the track grooves 111, the fixing screw holes 112 and the locking screws, the distance between the two terminal positioning posts 13 can be conveniently adjusted and fixed easily after adjustment, so as to adapt to speaker terminal boards of different types and sizes. Generally, there are two positioning holes on the speaker terminal board, and the terminal board can be positioned by sleeving the two positioning holes on the two terminal positioning posts 13.

[0040] In some alternative embodiments, the universal riveting jig for the speaker terminal board of the present application further includes: a baffle moving rod 15; the baffle moving rod 15 passes through a through hole (loose fit) on the support base 11 and can move relative to the support base 11; one end of the baffle moving rod 15 located on the third side is fixedly connected to the movable baffle 14 (for example, fastened by screws), and the end of the baffle moving rod 15 located on the fourth side is for an operator to hold and operate; the baffle moving rod 15 is used to connect the movable baffle 14 and the support base 11 and is used to drive the movable baffle 14 to move relative to the support base.

[0041] In some alternative embodiments, the universal riveting jig for the speaker terminal board of the present application further includes a limit screw rod 16 threadedly engaged with the movable baffle 14; the limit screw rod 16 passes through a positioning screw hole on the movable baffle 14 and abuts against the support base 11 for limiting the movable baffle. For example, driven by the baffle moving rod 15, after moving the movable baffle 14 to a suitable position, the limit screw rod 16 is tightened to abut against the support base 11, and the movable baffle 14 can be limited so that it cannot move back and forth.

[0042] In some alternative embodiments, there are two limit screws 16, arranged side by side, one on the left and one on the right, to better limit the movable baffle 14.

[0043] In some alternative embodiments, a groove 141 for avoiding the special-shaped structure of the speaker basket is formed on the movable baffle 14. For some special-shaped speaker baskets, in order to avoid interference with the jig of the present application, corresponding grooves 141 can be formed on the movable baffle 14 for the special-shaped structures thereon.

[0044] In some alternative embodiments, the universal riveting jig for the speaker terminal board of the present application further includes: a base 10 for fixing the support seat 11, and the base 10 and the support seat 11 can be fixedly connected by screws at the bottom. The base 10 can serve as the support structure of the entire jig.
