[0064] The following embodiments are described in detail. These embodiments are intended only as examples and do not limit the scope of the present invention. Furthermore, the drawings in the embodiments may omit unnecessary elements or elements that can be completed with conventional techniques to highlight the technical features of the present invention.

[0065] Please refer to Figures 1 to 8 According to a first embodiment of the present invention, a headset 1 is provided. The headset 1 includes a first earmuff component 2, a second earmuff component 3, an arc-shaped connecting strip 4, a clamping force adjustment component 5 and a shell 6.

[0066] The first earmuff assembly 2 includes a first speaker 21 and a first cover 22 . The second earmuff assembly 3 includes a second speaker 31 and a second cover 32 .

[0067] The arcuate connecting strip 4 connects the first earmuff assembly 2 and the second earmuff assembly 3. In the present invention, the arcuate connecting strip 4 can be directly or indirectly connected to the first earmuff assembly 2 or the second earmuff assembly 3. If a direct connection method is adopted, the arcuate connecting strip 4 directly extends from both sides and is fixed to the first earmuff assembly 2 and the second earmuff assembly 3. In an indirect connection method, at least one intermediate connecting member 7 is additionally provided between the arcuate connecting strip 4 and the first earmuff assembly 2, or between the arcuate connecting strip 4 and the second earmuff assembly 3, for example Figure 2 The yokes shown are used to connect the arcuate connecting strip 4 to the first earmuff assembly 2, and to connect the arcuate connecting strip 4 to the second earmuff assembly 3. Furthermore, in other embodiments of the present invention, the intermediate connecting member 7 may also be a slide rail or a slide groove for adjusting the distance between the arcuate connecting strip 4 and the first earmuff assembly 2, or between the arcuate connecting strip 4 and the second earmuff assembly 3, and the present invention is not limited thereto.

[0068] In this embodiment, the arcuate connecting strip 4 may be entirely or partially arcuate, and at least have a curved or bent arcuate shape at the portion contacting the first pressing plate 51 and the second pressing plate 52 of the clamping force adjustment assembly 5. Furthermore, the arcuate connecting strip 4 may be made of a metal sheet or a steel bar.

[0069] The arc-shaped connecting bar 4 has a first through hole 41 and at least one first positioning hole 42 . In this embodiment, the arc-shaped connecting bar 4 has two first positioning holes 42 , which are respectively disposed on both sides of the first through hole 41 .

[0070] The clamping force adjustment assembly 5 includes a first pressing plate 51 , a second pressing plate 52 , a slider 53 , a knob 54 , a bolt 55 , a positioning column 56 , a washer 57 and a nut 58 .

[0071] The first pressing plate 51 has a first mounting hole 511 and at least one second mounting hole 512. The inner edges of the first mounting hole 511 and the second mounting hole 512 have a plurality of parallel longitudinal grooves 5111 and 5121. In this embodiment, the first pressing plate 51 has two second mounting holes 512, which are arranged on both sides of the first mounting hole 511.

[0072] The second pressing plate 52 has a second through hole 521 and at least one second positioning hole 522 . In this embodiment, the second pressing plate 52 has two second positioning holes 522 , which are respectively disposed on both sides of the second through hole 521 .

[0073] The arc-shaped connecting strip 4 is sandwiched between the first pressing plate 51 and the second pressing plate 52 , and the curvature of the arc-shaped connecting strip 4 changes as the distance between the first pressing plate 51 and the second pressing plate 52 changes, so that the shape of the arc-shaped connecting strip 4 tends to be flat or returns to its original more curved shape.

[0074] Please refer to Figures 2 to 6 The slider 53 is located below the second pressure plate 52 in the drawings, that is, on the side of the second pressure plate 52 facing away from (or away from) the arcuate connecting strip 4. The slider 53 has a first screw hole 531 at its center, and the outer cross-section of the slider 53 is polygonal, arcuate, or irregular. In this embodiment, the outer cross-section of the slider 53 is a plum blossom shape.

[0075] Please refer to Figures 2 to 6 The knob 54 is located below the slider 53, that is, on the side of the slider 53 facing away from (or away from) the second pressure plate 52. The knob 54 has a receiving groove 541 in the center, which can be used to accommodate the slider 53 and allow the slider 53 to slide in the receiving groove 541. The cross-section of the inner edge of the receiving groove 541 is polygonal, arched or irregular, and the inner edge of the receiving groove 541 and the outer periphery of the slider 53 are consistent and complementary in appearance and size. In this embodiment, the cross-section of the inner edge of the receiving groove 541 is selected from the plum blossom shape. In addition, a third through hole 542 is provided in the center of the receiving groove 541.

[0076] The bolt 55 has a head 551, a first threaded portion 552, and a second threaded portion 553. The head 551 and the second threaded portion 553 are located at opposite ends of the bolt 55, while the first threaded portion 552 is located between the head 551 and the second threaded portion 553. Furthermore, the outer periphery of the head 551 has a plurality of parallel longitudinal grooves 5511. In this embodiment, a gap 554 is defined between the first threaded portion 552 and the second threaded portion 553, and no threads are provided within the area of ​​this gap 554. Furthermore, in this embodiment, the diameter of the first threaded portion 552 is greater than the diameter of the second threaded portion 553, but the present invention is not limited thereto.

[0077] The head 551 of the bolt 55 can be installed and fixed to the first mounting hole 511 of the first pressure plate 51. As previously described, because the outer periphery of the head 551 has a plurality of parallel longitudinal grooves 5511, and the inner edge of the first mounting hole 511 of the first pressure plate 51 also has a plurality of parallel longitudinal grooves 5111, and the longitudinal grooves 5511 on the head 551 and the longitudinal grooves 5111 in the first mounting hole 511 are mutually compatible and complementary in appearance and size, when the head of the bolt 55 is inserted into the first mounting hole 511 of the first pressure plate 51, the bolt 55 is fixed to the first pressure plate 51, and the two cannot rotate relative to each other. In other embodiments of the present invention, the head 551 of the bolt 55 and the first mounting hole 511 of the first pressure plate 51 can also form other corresponding and compatible shapes, such as polygonal, arched, or irregular shapes, which can prevent the two from rotating relative to each other after installation.

[0078] When assembling the clamping force adjustment assembly 5, the first threaded portion 552 of the bolt 55 sequentially passes through the first through-hole 41 of the arc-shaped connecting strip 4 and the second through-hole 521 of the second pressure plate 52, before being screwed into the first threaded hole 531 of the slider 53. Furthermore, the first threaded hole 531 of the slider 53 and the first threaded portion 552 of the bolt 55 align with each other in terms of their thread pattern, allowing the slider 53 and the bolt 55 to rotate relative to each other.

[0079] When the clamping force adjustment assembly 5 is assembled, as long as the slider 53 is moved toward the curved connecting bar 4 along the first threaded portion 552 of the bolt 55, the second pressure plate 52 and the first pressure plate 51 will compress the curved connecting bar 4 and deform it, causing the curved connecting bar 4 to change from a curved shape to a flat shape. Conversely, if the slider 53 is moved away from the curved connecting bar 4 along the first threaded portion 552, the second pressure plate 52 and the first pressure plate 51 will reduce or even stop compressing the curved connecting bar 4. During this process, the portion of the curved connecting bar 4 that contacts the first and second pressure plates 51 and 52 will change from a relatively flat shape to a more curved shape.

[0080] Since the two ends of the arc-shaped connecting strip 4 are respectively connected to the first earmuff assembly 2 and the second earmuff assembly 3, once the shape of the arc-shaped connecting strip 4 is deformed, the distance between the first earmuff assembly 2 and the second earmuff assembly 3 will also change accordingly, for example, becoming larger or smaller, and the clamping force exerted by the first earmuff assembly 2 and the second earmuff assembly 3 on the user's head will naturally change, for example, becoming looser or tighter.

[0081] In this embodiment, the user does not directly move the slider 53. Instead, the user drives the slider 53 via a knob 54 that can rotate in place. As previously mentioned, in this embodiment, the outer cross-section of the slider 53 is a plum blossom shape, and the inner cross-section of the knob 54's receiving groove 541 also has a corresponding plum blossom shape, with the two matching each other. Thus, when the user turns the knob 54, the receiving groove 541 of the knob 54 drives the slider 53 to rotate synchronously. Once the slider 53 rotates and moves up and down along the bolt 55, it further changes the distance between the first pressure plate 51 and the second pressure plate 52, causing the arc-shaped connecting strip 4 to deform in appearance.

[0082] In the present invention, the clamping force adjustment assembly 5 is installed and disposed in the housing 6. Figure 5 At least one stud 61 is disposed on the inner side of the housing 6, and at least one third mounting hole 513 is disposed on the first pressure plate 51. In this embodiment, the first pressure plate 51 of the clamping force adjustment assembly 5 can be fixed to the housing 6 by inserting a screw 62 through the third mounting hole 513 of the first pressure plate 51 and then locking it into the bolt 55.

[0083] Furthermore, the housing 6 is generally arc-shaped and hollow, housing the arc-shaped connecting strip 4, the clamping force adjustment assembly 5, and a portion of the intermediate connector 7. The housing 6 has an opening 63, through which the knob 54 of the clamping force adjustment assembly 5 is partially exposed, allowing the user to rotate it to adjust the clamping force between the first earmuff assembly 2 and the second earmuff assembly 3 on the user's head. Furthermore, during adjustment, the knob 54 only rotates in place and does not move up and down along the bolt 55. This design prevents the knob 54 from getting stuck in the opening 63 and also prevents the opening 63 from being too large, thereby affecting the overall appearance of the headphone 1. Furthermore, in the clamping force adjustment assembly 5 provided by the present invention, except for the partially exposed knob 54, all other components are concealed within the housing 6. This design also reduces the possibility of the knob 54 becoming entangled in the user's hair or pinching the user's scalp.

[0084] In the process of adjusting the clamping force, in order to prevent the first pressure plate 51, the arc-shaped connecting strip 4 and the second pressure plate 52 from rotating relative to each other or to reduce the amplitude of the relative rotation, the clamping force adjustment assembly 5 provided in this embodiment is also specially provided with at least one positioning column 56, and correspondingly, a second mounting hole 512 is provided on the first pressure plate 51, at least one first positioning hole 42 is provided on the arc-shaped connecting strip 4, and at least one second positioning hole 522 is provided on the second pressure plate 52. The positioning column 56 has a head 561, and the periphery of the head 561 has a plurality of parallel longitudinal grooves 5611, and the inner edge of the second mounting hole 512 of the first pressure plate 51 also has a corresponding plurality of parallel longitudinal grooves 5121, and the longitudinal grooves 5611 on the head 561 and the longitudinal grooves 5121 in the second mounting hole 512 are consistent and complementary to each other in appearance and size. Therefore, when the head 561 of the positioning column 56 is inserted into the second mounting hole 512 of the first pressure plate 51, the positioning column 56 can be fixed on the first pressure plate 51, and the two will not rotate relative to each other.

[0085] Furthermore, when assembling the clamping force adjustment assembly 5, the positioning post 56 fixed on the first pressure plate 51 passes through the first positioning hole 42 of the arc-shaped connecting strip 4 and is inserted into the second positioning hole 522 of the second pressure plate 52. In this way, the first pressure plate 51, the arc-shaped connecting strip 4, and the second pressure plate 52 will not rotate relative to each other, or the amplitude of relative rotation will be reduced.

[0086] Furthermore, in this embodiment, the clamping force adjustment assembly 5 further includes a washer 57 and a nut 58, wherein the washer 57 includes a fourth through hole 571. When the various components of the clamping force adjustment assembly 5 are assembled, the second threaded portion 553 of the bolt 55 sequentially passes through the first through hole 41 of the arc-shaped connecting bar 4, the second through hole 521 of the second pressure plate 52, the first screw hole 531 of the slider 53, the third through hole 542 of the knob 54, and the fourth through hole 571 of the washer 57, and then screws onto the nut 58, thereby completing the assembly of the knob 54, the slider 53, the second pressure plate 52, the arc-shaped connecting bar 4, and the first pressure plate 51.

[0087] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Therefore, any other equivalent changes or modifications that do not depart from the spirit disclosed in the present invention should be included in the inventive concept of the invention.
