[0035] Specifically, bearing 2 rotates between first connection position and second connection position;When bearing 2 is in first connection position, first pole piece 21 is abutted on positive contact 11, and second pole piece 22 is abutted on negative contact 12;When bearing 2 is in second connection position, first pole piece 21 is abutted on negative contact 12, and second pole piece 22 is abutted on positive contact 11, bearing 2 realizes the conversion of circuit connection by rotating between first connection position and second connection position, simple structure, convenient operation.
[0036] Specifically, positive and negative interfaces are arranged on circuit board 1, and the positive and negative interfaces are used to externally connect debugging equipment;The specific structure of bearing 2 and the specific arrangement positions of first pole piece 21 and second pole piece 22 can be arranged according to actual needs, as long as the shapes of left earphone and right earphone can be simultaneously adapted.In this regard, no limitation is made.
[0037] Further, as shown, Figure 2 Positive contact 11 and negative contact 12 are both in strip shape, and positive contact 11 and negative contact 12 are arranged in parallel and spaced apart;Circuit board 1 and bearing 2 are arranged in vertical stacking, and bearing 2 is arranged above circuit board 1, circuit board 1 is in rectangular plate structure, positive contact 11 and negative contact 12 are both arranged on the side of circuit board 1 facing bearing 2, and the end portions of first pole piece 21 and second pole piece 22 are both arranged on the side of bearing 2 facing circuit board 1.
[0038] The specific connection mode of the circuit board 1 and the carrier 2 can be set according to actual needs, and only the carrier 2 can rotate between the first connection position and the second connection position; the earphone connecting jig also includes a connecting shaft 3, the connecting shaft 3 is arranged in the circuit board 1 and the carrier 2, and the carrier 2 rotates around the connecting shaft 3. The carrier 2 is located above the circuit board 1.
[0039] In order to improve the stability of the circuit of the earphone during detection, the earphone connecting jig also includes a resilient member, the circuit board 1 and the carrier 2 move axially along the connecting shaft 3, the resilient member is arranged on the connecting shaft 3 and is configured to drive the circuit board 1 and the carrier 2 to abut against each other, thereby ensuring that the pole piece on the carrier 2 and the contact on the circuit board 1 abut firmly and are not easy to loosen.
