The following is a detailed description of an embodiment. The embodiment is only used as an example and does not limit the scope of protection of this creation. In addition, the diagrams in the embodiment will also omit unnecessary elements or elements that can be completed with conventional technology to highlight the technical features of this creation.

Please refer to Figures 1 to 7. According to the first embodiment of this invention, a headphone 1 is provided. The headphone 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 housing 6.

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.

The arc-shaped connecting strip 4 connects the first earmuff assembly 2 and the second earmuff assembly 3. In the present invention, the arc-shaped connecting strip 4 can directly or indirectly connect the first earmuff assembly 2 or the second earmuff assembly 3. If a direct connection method is adopted, it means that the arc-shaped connecting strip 4 directly extends from both sides and is fixed on the first earmuff assembly 2 and the second earmuff assembly 3. The indirect connection method means that at least one intermediate connecting member 7 is additionally provided between the arc-shaped connecting strip 4 and the first earmuff assembly 2, or between the arc-shaped connecting strip 4 and the second earmuff assembly 3, such as the yoke shown in FIG. 2 to connect the arc-shaped connecting strip 4 and the first earmuff assembly 2, and to connect the arc-shaped connecting strip 4 and the second earmuff assembly 3, respectively. In addition, in other embodiments according to the present invention, the intermediate connecting member 7 can also be selected from a slide rail or a slide groove used to adjust the distance between the arc-shaped connecting strip 4 and the first earmuff assembly 2 or between the arc-shaped connecting strip 4 and the second earmuff assembly 3, and the present invention is not limited thereto.

In this embodiment, the arc-shaped connecting strip 4 may have an arc-shaped appearance in whole or in part, and at least the portion contacting the first pressing plate 51 and the second pressing plate 52 in the clamping force adjustment assembly 5 may have a curved or bent arc-shaped appearance. In addition, the arc-shaped connecting strip 4 may be selected from a metal sheet or a metal steel bar.

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

The clamping force adjustment assembly 5 includes a first pressure plate 51, a second pressure plate 52, a slide block 53, a knob 54, a bolt 55, a positioning column 56, a gasket 57 and a nut 58.

The first pressing plate 51 has a first mounting hole 511 and at least one second mounting hole 512, and 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, and they are arranged on both sides of the first mounting hole 511.

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 arranged on both sides of the second through hole 521.

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 curved shape.

Please refer to Figures 2 to 6. The slider 53 is located below the second pressing plate 52 in the figure, that is, located on the side of the second pressing plate 52 facing away from (or away from) the arc-shaped connecting strip 4. The center of the slider 53 has a first screw hole 531, and the cross-section of the outer periphery of the slider 53 is a polygon, an arc or an irregular shape. In this embodiment, the cross-section of the outer periphery of the slider 53 is selected from a plum blossom shape.

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 a plum blossom shape. In addition, the center of the receiving groove 541 has a third through hole 542.

The bolt 55 has a head 551, a first threaded portion 552 and a second threaded portion 553, wherein the head 551 and the second threaded portion 553 are located at two ends of the bolt 55, and the first threaded portion 552 is located between the head 551 and the second threaded portion 553. In addition, the outer periphery of the head 551 has a plurality of parallel longitudinal grooves 5511. In this embodiment, there is a gap 554 between the first threaded portion 552 and the second threaded portion 553, and no thread is arranged in the area of the gap 554. In addition, in this embodiment, the diameter of the first threaded portion 552 is larger than the diameter of the second threaded portion 553, but the invention is not limited thereto.

The head 551 of the bolt 55 can be installed and fixed on the first mounting hole 511 of the first pressing plate 51. As mentioned above, since 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 pressing 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 matched and complementary in appearance and size, when the head of the bolt 55 is inserted into the first mounting hole 511 of the first pressing plate 51, the bolt 55 can be fixed on the first pressing plate 51, and the two will not rotate relative to each other. In other embodiments of the invention, the head 551 of the bolt 55 and the first mounting hole 511 of the first pressure plate 51 can also form other shapes that correspond to and match each other, such as polygons, arches, or irregular shapes, which can prevent the two from rotating relative to each other after installation.

When assembling the clamping force adjustment assembly 5, the first threaded portion 552 of the bolt 55 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 in sequence, and then is screwed into the first screw hole 531 of the slider 53. In addition, the first screw hole 531 of the slider 53 and the first threaded portion 552 of the bolt 55 match each other in terms of the texture, so the slider 53 and the bolt 55 can rotate relative to each other.

When the clamping force adjustment assembly 5 is assembled, the slider 53 is moved along the first threaded portion 552 of the bolt 55 toward the arc-shaped connecting strip 4. The second pressing plate 52 and the first pressing plate 51 will press the arc-shaped connecting strip 4 and cause it to deform. During the process, the shape of the arc-shaped connecting strip 4 will change from curved to flat. On the contrary, if the slider 53 is moved and moved away from the arc-shaped connecting strip 4 along the first threaded portion 552, the second pressing plate 52 and the first pressing plate 51 will reduce or stop pressing the arc-shaped connecting strip 4. During the process, the portion of the arc-shaped connecting strip 4 that contacts the first pressing plate 51 and the second pressing plate 52 will change from a relatively flat shape to a relatively curved shape.

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, such as 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, such as becoming loose or tight.

In this embodiment, the user does not directly move the slider 53, but drives the slider 53 to move by means of the knob 54 that can rotate in place. As mentioned above, in this embodiment, the cross-section of the outer periphery of the slider 53 is a plum blossom shape, and the cross-section of the inner edge of the knob 54 receiving groove 541 is also a corresponding plum blossom shape, and the two are consistent with each other. In this way, when the knob 54 is turned by the user, the receiving groove 541 of the knob 54 can drive the slider 53 to rotate synchronously. Once the slider 53 rotates and moves up and down along the bolt 55, the distance between the first pressing plate 51 and the second pressing plate 52 can be further changed, and the arc-shaped connecting strip 4 can be deformed in appearance.

In this invention, the clamping force adjustment assembly 5 is installed and arranged in the housing 6. Referring to FIG. 5 , at least one stud 61 is arranged on the inner side of the housing 6, and at least one third mounting hole 513 is arranged 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 passing the screw 62 through the third mounting hole 513 of the first pressure plate 51 and then locking it into the stud 61.

In addition, the housing 6 is generally arc-shaped and has a hollow structure, which is used to accommodate the arc-shaped connecting strip 4, the clamping force adjustment component 5 and part of the intermediate connecting member 7. The housing 6 has an opening 63, and the knob 54 of the clamping force adjustment component 5 is partially exposed from the opening 63, so that the user can adjust the clamping force of the first earmuff component 2 and the second earmuff component 3 on the user's head after turning it. In addition, during the adjustment process, the knob 54 will only rotate in place and will not move up and down along the bolt 55. Such a design can prevent the knob 54 moving up and down from getting stuck in the opening 63, and the range of the opening 63 does not need to be set too large to affect the overall appearance of the headphone 1. In addition, in the clamping force adjustment assembly 5 provided by the present invention, except for the partially exposed knob 54, the other components are hidden in the housing 6. Such a design can also reduce the possibility of getting caught in the user's hair or clamping the user's scalp.

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 producing relative rotation or to reduce the amplitude of 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 outer 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 pressing plate 51 also has a plurality of corresponding 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 mutually matched and complementary in appearance and size, so when the head 561 of the positioning column 56 is inserted into the second mounting hole 512 of the first pressing plate 51, the positioning column 56 can be fixed on the first pressing plate 51, and the two will not rotate relative to each other.

In addition, when assembling the clamping force adjustment assembly 5, the positioning column 56 fixed on the first pressure plate 51 will pass through the first positioning hole 42 of the arc-shaped connecting strip 4 and then be 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 relative rotation range will be reduced.

In addition, in this embodiment, the clamping force adjustment assembly 5 also includes a gasket 57 and a nut 58, wherein the gasket 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 will sequentially pass through the first through hole 41 of the arc-shaped connecting strip 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 gasket 57, and then be screwed onto the nut 58, thereby completing the assembly of the knob 54, the slider 53, the second pressure plate 52, the arc-shaped connecting strip 4, and the first pressure plate 51.

The above is only the best implementation example of this creation and is not intended to limit this creation. Therefore, any other equivalent changes or modifications that do not deviate from the spirit revealed by this creation should be included in the creative concept of this case.
