[0024] This utility model is a type of over-ear headphone, which will be further described below with reference to the accompanying drawings.

[0025] See Figures 1 to 8 As shown, this utility model includes: an earphone part 1, a fork 2, and a connecting arm 3. The earphone part 1 has a built-in speaker to output sound. The fork 2 is C-shaped, with one end connected to the earphone part 1 via a pin 21, and the other end connected to the connecting arm 3 via a connecting unit at its middle position.

[0026] Combination Figure 7 , Figure 8As shown, the connecting unit includes: a connecting seat 4, a first fixing block 5, and a second fixing block 6. The first fixing block 5 is fixedly connected to the connecting arm 3; the second fixing block 6 is fixedly connected to the fender 2; the connecting seat 4 connects the first fixing block 5 and the second fixing block 6, ultimately achieving the connection between the fender 2 and the connecting arm 3.

[0027] The following describes the fixed connection structure between the frill 2 and the second fixing block 6.

[0028] The outer side of the middle position of the fork rib 2 has a mounting groove 20 for accommodating the second fixing block 6, and the cross-section of the mounting groove 20 is adapted to the second fixing block 6. The second fixing block 6 has a shaft hole 61 in the middle, and second threaded holes 62 are respectively formed on both sides of the shaft hole 61. The screw 7 passes through the second threaded holes 62 and is threadedly connected to the fork rib 2. In this way, the second fixing block 6 is fixed to the fork rib 2.

[0029] The mounting groove 20 of the fork 2 has a wire through hole 201. The inner walls of both ends of the fork 2 are provided with pins 21 that connect to the earphone part 1. One of the pins 21 has a hollow structure. A wire groove 22 is formed along the inner wall of the fork 2, connecting the wire through hole 201 and the hollow pin 21. The wire in the earphone part 1 extends out from the hollow pin 21, extends along the wire groove 22, enters through the wire through hole 201, passes through the connecting seat 4 and the first fixing block 5, and enters the connecting arm 3. After passing through the connecting bracket body of the headphone, it enters the earphone part on the other side in the same way, realizing the electrical connection between the left and right earphone parts in the headphone.

[0030] The following describes the fixed connection structure between the connecting arm 3 and the first fixing block 5.

[0031] The connecting arm 3 is made of aluminum or aluminum alloy and serves as part of the connecting bracket in the headphones. Typically, this connecting arm 3 is slidably connected to the main body of the headphone connecting bracket, enabling the entire connecting bracket to be telescopically adjustable.

[0032] The connecting arm 3 has a slot 30 at its end for inserting the first fixing block 5, and a threaded seat 31 is integrally formed on the inner wall of the slot 30. The first fixing block 5 has guide grooves 510 on its opposite sides corresponding to the threaded seat 31, and a blocking block 52 is formed at the end of the guide groove 510, and the blocking block 52 has a first threaded hole 520 for inserting a screw.

[0033] The cross-section of the slot 30 in the connecting arm 3 is adapted to the cross-section of the first fixing block 5. When the first fixing block 5 is inserted along the slot 30, the threaded seat 31 slides along the guide grooves 510 on both sides of the first fixing block 5 until the threaded seat 31 presses against the blocking block 52. At this time, the screw 7 is threaded through the first threaded hole 520 and then threadedly connected to the threaded seat 31. In this way, the first fixing block 5 is fixedly connected to the connecting arm 3, and the whole fixing structure is simple and very convenient to assemble.

[0034] The following describes the structure in which the first fixing block 5 and the second fixing block 6 are connected by the connecting seat 4.

[0035] The connecting base 4 is typically made of metal and includes an integrally formed pivot base 41 and a connecting shaft 42. A pivot 43 is provided on the pivot base 41. The pivot base 41 is pivotally connected to the first fixing block 5 via the pivot 43, enabling swinging along the X-axis. The connecting shaft 42 is pivotally connected to the shaft hole 61 in the second fixing block 6, and the shaft hole 61 through which the connecting shaft 42 passes connects to a retaining spring 45, enabling swinging along the Y-axis. Additionally, the connecting base 4 has a connecting channel 40 that passes through the pivot base 41 and the connecting shaft 42, serving as a passage for the headphone cable to pass through.

[0036] The first fixing block 5 includes a base 53 with a cross-section corresponding to the slot 30 and ear plates 51 integrally extended from both sides of the base 53. The outer surfaces of the two ear plates 51 are formed with guide grooves 510, and a space 50 for accommodating the pivot seat 41 is formed between the two ear plates 51. A pivot groove 511 is formed on both ear plates 51 at the same position near the space 50. The pivot groove 511 cooperates with the pivot 43 in the connecting seat 4. When the first fixing block 5 is inserted into the slot 30 of the connecting arm 3, the connecting arm 3 will close the opening of the pivot groove 511, forming a closed pivot hole.

[0037] In addition, a groove 530 corresponding to the connecting channel 40 on the connecting seat 4 is provided on the base 53, and the groove 530 is used for the earphone wire to pass through.

[0038] When assembling this utility model, the second fixing block 6 is first connected to the connecting seat 4. The connecting shaft 42 in the connecting seat 4 is inserted into the shaft hole 61 in the second fixing block 6. The shaft hole 61 through which the connecting shaft 42 passes is connected to the snap ring 45. The second fixing block 6 and the connecting seat 4 are then connected together.

[0039] Next, the second fixing block 6 is placed in the mounting groove 20 of the fork 2, and then the second fixing block 6 is fixed to the fork 2 by screws 7.

[0040] Finally, after combining the connecting seat 4 and the first fixing block 5, insert them together into the slot 30 of the connecting arm 3. After rotating the fork 2 to drive the second fixing block 6 to rotate at a certain angle, the threaded hole 520 is exposed. Then, the first fixing block 5 is fixed in the slot 30 by the screw 7.

[0041] In addition, to ensure that the connecting seat 4 can swing smoothly relative to the first fixed block 5, a notch 32 is formed at the position of the connecting arm 3 corresponding to the interval space 50. In this way, when the connecting seat 4 swings around the pivot 43, the notch 32 provides the pivot seat 41 with reserved swing space.

[0042] Furthermore, combining Figure 6 As shown, a protrusion 44 is formed on the side of the pivot seat 41 adjacent to the base 53, and an elastic retaining strip 54 that interferes with the protrusion 44 is provided in the space 50 of the first fixing block 5. The elastic retaining strip 54 provides elastic damping to reset the protrusion 44.

[0043] Of course, the above description is only a specific embodiment of the present utility model and is not intended to limit the scope of the present utility model. All equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model should be included in the scope of the claims of the present utility model.
