The base 20 includes a base 21 and a boss 22 protruding from the top of the base 21. The outer circumference of the boss 22 is smaller than the outer circumference of the base 21. The boss 22 is used to be inserted into the through hole of the sound box housing. The base 20 is penetrated by a plurality of installation holes 23 arranged at intervals. The installation holes 23 sequentially penetrate the boss 22. And the base 21, each PIN needle 11 is installed in each installation hole 23 respectively, the waterproof ring 30 is annular, the waterproof ring 30 is sleeved on the boss 22, the waterproof ring 30 is made of silicone material, the base 20 is made of plastic material, and the waterproof ring 30 is installed on the base 21 through the beer sleeve process, the waterproof ring 30 is used to abut against the inner wall of the outer shell, the waterproof ring 30 and the base 20 are molded and combined as a whole, even in some occasions with limited space, the waterproof ring 30 will not be separated from the base 20, thereby improving the good waterproof effect of the waterproof socket.
[0035] The base 20 also includes a plurality of limit posts 24, each of which is protruding from the base 21, and each of which is arranged outside the boss 22. The waterproof ring 30 is penetrated by a plurality of limit holes 31, and each of the limit posts 24 is inserted into each of the limit holes 31. In some occasions where space is limited, the cooperation between the limit posts 24 and the limit holes 31 can play a limiting role, which can further prevent the waterproof ring 30 from being separated from the base 20, and at the same time make the compression ratio of the waterproof ring 30 more accurate, so that the distance from the base 21 to the outer shell surface of the speaker can also be accurately controlled, which is convenient for mass production with good performance consistency. The material of the limit posts 24 is plastic.
[0036] In some embodiments, the terminal 10 is made of metal and the base 20 is made of plastic. The terminal 10 and the base 20 are fixed together through an in-mold forming process, so that the terminal 10 and the base 20 are combined together during the manufacturing process to achieve a tight connection without loosening.
[0037] Please read further Figures 3 to 9In this embodiment, the waterproof ring 30 includes an annular support pad 32 and an annular sealing portion 33. The annular support pad 32 is sleeved on the boss 22, and the annular support pad 32 is fixed on the base 21. The annular sealing portion 33 is protruded on the side of the annular support pad 32 away from the base 21. When the waterproof socket is installed in the speaker, the annular sealing portion 33 is used to abut against the inner wall of the outer shell to waterproof the waterproof socket. The limiting hole 31 is provided on the annular support pad 32.
[0038] In some embodiments, the cross-section of the annular sealing portion 33 is triangular, and the thickness of the annular sealing portion 33 gradually increases from the end away from the base 21 to the end close to the base 21. The waterproofing between the waterproof socket and the shell utilizes the tip of the triangular annular sealing portion 33. A very small pre-pressure is applied to compress the tip of the annular sealing portion 33 through the shell to achieve a waterproof effect. When the compression amount of the tip of the annular sealing portion 33 is controlled at 0.2-0.3 mm, the waterproof level of 7 or above can be achieved.

[0042] The base 21 includes a substrate 212, a baffle 213 and two side plates 214. The boss 22 and the limiting column 24 are both protruded on one side of the substrate 212, i.e., the top. The baffle 213 and the side plate 214 are both protruded on the side of the substrate 212 away from the boss 22, i.e., the bottom. The two side ends of the baffle 213 are respectively connected to the two side plates 214. The second hole section 232 passes through the boss 22 and the substrate 212 in sequence from the bottom wall of the first hole section 231. The limiting cavity 233 is provided on the baffle 213. Of course, the base 21 can also be other structural forms.
