The utility model discloses a use method as follows:

the L-pole lead of the loudspeaker is welded at the longest conductive sheet head, then the R +, L + and R-pole leads of the loudspeaker are welded on the three conductive sheets 1 in sequence according to the anticlockwise direction prevention, and after the welding is finished, the connector is pressed down to conduct a 4.4mm plug. After the 2.5mm plug is replaced, the connector is pulled up, rotated anticlockwise by 135 degrees and pressed down, and the 2.5mm plug is conducted.

The principle of the utility model is as follows:

the first elastic sheet is required to be capable of fixing the 4.4mm plug and the 2.5mm plug, and the 2.5mm plug chuck is required to be above the 4.4mm chuck. Then the lower half of the 2.5 plug would need to be extended and the extension fixed at 4.4mm diameter. The first spring plate (fig. 1) is designed as a conductive elastic metal plate, and the fixing positions of the first spring plate and the plugs with different sizes are shown in fig. 10 and fig. 11.

The vertical position of the 2.5mm plug and the 4.4mm plug using the conductive spring of the plug, depending on the position in which the chuck is fixed, should be as shown in fig. 12. The second elastic sheet (figure 2) is an elastic conducting sheet which can be compatible with 2.5mm and 4.4mm in outer diameter; spring plate three (fig. 3) is an elastic conductive sheet suitable for 4.4mm outer diameter.

According to the position of the plug, 6 conducting strips are needed to complete the wiring of two types of plugs, the R-of the 2.5mm plug is connected with the L + of the 4.4mm plug through the clamping head, and in addition, one conducting strip needs to be shared because the spatial positions of the L-of the two types of plugs are overlapped.

The second and third elastic sheets need to be welded on the long conducting strip (figure 4) to fix the horizontal position, 8 vertical grooves are arranged in the support ring (figure 5), 7 groove positions are used for 6 elastic sheets, and two groove positions are used for the first elastic sheet. The upper head of the long conductive strip (fig. 4) acts as the contact point, with the L-connected strip being longer than the other strips. The mounting position of the conductive plate is fixed as shown in fig. 13. The conducting strip can be inserted from the lower part of the supporting ring, after the conducting strip is fixed, the plug fixing supporting ring (shown in figure 6) is bonded at the lower part of the conducting strip supporting ring (shown in figure 5), the hole position in the supporting ring is 4.4mm, and the plug supporting ring can fix the central position of the plug when the plug is inserted. A conductive sheet supporting ring cover (figure 6) is bonded on the upper part of the supporting ring, and the cover and the ring barrel can be formed at one time during forming. The conductive sheet supporting ring wall is provided with a cylindrical bulge for fixing the position of the connector.

As shown in fig. 9, the connector structure is a switching structure for connecting the speaker unit L + L-R + R-output line and the plug long conductive sheet. Short contact pads (fig. 9) are used to fit into the 3 ports of the connector (fig. 14) and long pads L-extend from the annular groove for soldering the speaker L-leads. The middle of the connector is provided with a hole which is aligned with the center of the middle ring of the conductive sheet supporting ring cover, and the horizontal position is fixed by adopting a nut gasket. The connector structure and the lower spring ring structure can rotate relatively. The fixed connector has slot in the side for clamping the cylinder to limit the rotation angle. Since the same conductive strip is used for the L-of the 2.5mm and 4.4mm plugs, the three contact positions of L + R + R-need to be switched when two plugs are inserted. The positions of the 2.5mm conducting strips and the 4.4mm conducting strips are arranged in the same sequence of R-L + R +, and the 2.5mm and 4.4mm plugs can be conducted in a compatible mode after rotating contact.

The content of the present invention is not limited to the examples, and any equivalent transformation adopted by the technical solution of the present invention is covered by the claims of the present invention by those skilled in the art through reading the present invention.
