[0061] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0062] The terms "a", "an", "the", and "said" are used to indicate the presence of one or more elements / components / etc.; the terms "comprising" and "having" are used to express an open-ended inclusive meaning and mean that additional elements / components / etc. may be present in addition to the listed elements / components / etc.

[0063] An embodiment of the present invention provides a headset, such as Figure 2-12As shown, the earmuff rotating mechanism comprises a rotating member 1, a resistance pad 2 and a balance frame 3. The rotating member 1 is connected to the arm assembly 100 and the ear shell assembly 200. The ear shell assembly 200 comprises an ear shell 210 and an earmuff 220 fixed to the ear shell 210. The ear shell 210 is rotatably connected to the rotating member 1 on one side away from the earmuff 220. One side of the resistance pad 2 is connected to the side of the arm assembly 100 close to the ear shell 210, and the other side of the resistance pad 2 is elastically abutted against the outer side of the ear shell 210. The balance frame 3 is arranged on the inner side of the ear shell 210, the middle part of which is connected to the rotating member 1, and the outer periphery of which is abutted against the inner side of the ear shell 210. The resistance pad 2 and the balance frame 3 are pressed against the inner and outer sides of the ear shell 210 together. In this embodiment, the ear shell 210 and the earmuff 220 rotate relative to the arm assembly 100 through the rotating member 1. The resistance pad 2 elastically presses against the outer side of the ear shell 210, increasing the resistance to the rotation of the ear shell 210 and improving the hand feel; the resistance pad 2 can also cooperate with the balance frame 3 to clamp the inner and outer sides of the ear shell 210 at the same time to prevent shaking during the rotation process, and can keep the ear shell 210 at a set angle after the external force is removed. In this way, this example can not only realize the full rotation of the ear shell 210 and the earmuff 220 to meet the angle requirements of different users, but also prevent the ear shell 210 and the earmuff 220 from shaking during the rotation process, thereby improving the stability of the product and the user's experience.

[0064] In a preferred embodiment of the present invention, Figure 3 , 4 The earmuff rotation mechanism shown in FIG5 further includes a balance screw 4, which passes through the balance frame 3 and is threadedly connected to the rotating member 1, wherein the balance frame 3 can be pressed or loosened by rotating the balance screw 4 to increase or decrease the rotation force of the ear shell assembly 200. In the present application, the balance frame 3 and the rotating member 1 are detachably connected. Preferably, the balance frame 3 and the rotating member 1 are clamped, and the balance screw 4 passes through the balance frame 3 and is threadedly connected to the rotating member 1, so as to prevent the balance frame 3 from coming out. The balance frame 3 can also be driven to move along the central axis of the rotating member 1 toward or away from the ear shell 210 by rotating the balance screw 4, so that the elastic support arm 32 on the outer periphery of the balance frame 3 increases or decreases the pressure on the ear shell 210, thereby affecting the rotation force of the ear shell 210. Of course, for some special cases, after determining the rotation force of the ear shell 210, the balance frame 3 and the rotating member 1 can be fixed by gluing or other methods, and the present application does not limit this.

[0065] In a preferred embodiment of the present invention, Figure 2-5The rotating member 1 shown includes a rotating block 11 and a rotating column 12, wherein the rotating block 11 is hemispherical, and the rotating column 12 is fixed to the side of the arm assembly 100 close to the ear shell 210, and the rotating column 12 is fixed to the side of the rotating block 11 close to the ear shell 210. The free end of the rotating column 12 passes through the ear shell 210 and is connected to the balance frame 3 and the balance screw 4, wherein the rotating column 12 is provided with a threaded hole 121 along its axial direction, the main body of the balance screw 4 passes through the balance frame 3 and is threadedly connected to the threaded hole 121, and the nut portion of the balance screw 4 abuts against the side of the balance frame 3 away from the arm assembly 100, and the balance frame 3 is pressed or loosened by rotating the balance screw 4, thereby increasing or decreasing the rotation force of the ear shell 210.

[0066] In the present application, the support arm lower cover 102, the rotating block 11 and the rotating column 12 are integrally formed, and the central axes of the rotating block 11 and the rotating column 12 are collinear. Since the main body of the balancing screw 4 is threadedly connected to the threaded hole 121, the central axes of the balancing screw 4, the rotating column 12 and the rotating block 11 are collinear. Because the outer periphery of the rotating block 11 is rotatably connected to the ear shell 210 and can rotate along the central axis of the rotating block 11, when the speaker wire passes through the wire hole 41 on the balancing screw 4 and enters the interior of the support arm assembly 100, it will not be affected by the rotation of the ear shell 210.

[0067] In a preferred embodiment of the present invention, Figure 2-7 The outer side of the ear shell 210 is inwardly recessed to form a rotation groove 2101 corresponding to the rotation block 11. The rotation groove 2101 is provided with a first through hole 2102 for the rotation column 12 to pass through. The ear shell 210 is sleeved on the outer periphery of the rotation block 11 through the rotation groove 2101 and can rotate along the central axis of the rotation block 11. The inner wall of the rotation groove 2101 is hemispherical, and the rotation groove 2101 is sleeved on the outer periphery of the rotation block 11 and can rotate along the central axis of the rotation block 11.

[0068] In a preferred embodiment of the present invention, Figure 2 , 5The balance frame 3 shown in FIGS. 6, 8-10 includes a balance block 31 and a plurality of elastic arms 32. The side of the balance block 31 close to the ear shell 210 is recessed toward the inner side of the ear shell 210 to form a limiting groove 311 on the inner periphery. The limiting groove 311 is sleeved on the outer periphery of the rotating groove 2101 and connected to the rotating column 12. The plurality of elastic arms 32 are evenly distributed along the outer periphery of the balance block 31, and each elastic arm 32 abuts against the inner side of the ear shell 210. In the present application, the balance frame 3 is made of ABS plastic. Other suitable rubber materials can also be selected according to the required comfort of wearing. The plurality of elastic arms 32 are evenly distributed on the inner side of the ear shell 210 to ensure that the ear shell 210 is subjected to balanced force and does not shake during the rotation process. In addition, the inner wall of the limit groove 311 is also hemispherical, and the inner wall of the limit groove 311 is sleeved on the outer side of the rotation groove 2101. The limit groove 311 and the rotation groove 2101 are matched with each other. As the balancing screw 4 is rotated, the balancing frame 3 can be driven to approach the ear shell 210 so that the gap between the limit groove 311 and the rotation groove 2101 is zero, and the ear shell 210 rotates around the spherical surface formed between the limit groove 311 and the rotation block 11. As the balancing frame 3 continues to approach and presses the ear shell 210 with the elastic support arm 32, the rotation force of the ear shell 210 increases suddenly, and as the balancing screw 4 fixes the balancing frame 3 and the ear shell 210 on the rotation block 11, the angle of the ear shell 210 cannot be rotated. That is, the structure of the present application can realize the rotation requirements of the ear shell 210 and the earmuff 220, and the ear shell 210 and the earmuff 220 can also be assembled into a mode in which the angle cannot be adjusted, which meets different production requirements and has a wide range of applications.

[0069] In a preferred embodiment of the present invention, Figure 2-4 The free end of the rotating column 12 shown in Figures 8-10 is provided with a protrusion 122, and the bottom of the limiting groove 311 is provided with a second groove 312 corresponding to the protrusion 122, and the protrusion 122 is inserted into the second groove 312 to realize the connection between the balance frame 3 and the rotating column 12; wherein, the second groove 312 is provided with a second through hole 313 corresponding to the balancing screw 4, and the main body of the balancing screw 4 passes through the second through hole 313 and is connected to the threaded hole 121. Figure 3-4 As shown in FIG. 9 , the rotating column 12 is provided with a protrusion 122, and the bottom of the limiting groove 311 is provided with a second groove 312. The protrusion 122 is inserted into the second groove 312 to achieve the connection between the balance frame 3 and the rotating column 12, wherein the depth of the protrusion 122 inserted into the second groove 312 determines the gap between the mounting frame 3 and the ear shell 210, and the balancing screw 4 can adjust the fitting depth between the two, thereby adjusting the adjustment force of the ear shell 210.

[0070] In a preferred embodiment of the present invention, Figure 2 , 4The ear shell 210 shown in FIG. 10 is concave outwardly on one side close to the arm assembly 100 to form a first groove 2103 for mounting the balance weight 31, and the notch of the limiting groove 311 is inserted into the first groove 2103; wherein, the bottom of the first groove 2103 is concave inwardly to form a rotation groove 2101. In this embodiment, the first groove 2103 can increase the space behind the speaker 62, and since the notch of the limiting groove 311 is inserted into the first groove 2103, it will not occupy too much space behind the speaker 62, and the sound quality can be improved.

[0071] In a preferred embodiment of the present invention, Figure 2 , 4 Each elastic arm 32 shown in FIG. 10 includes a straight segment 321 and an arc segment 322. One end of the straight segment 321 is connected to the notch of the limiting groove 311, and the other end of the straight segment 321 extends in a direction away from the first groove 2103. One end of the arc segment 322 is connected to the other end of the straight segment 321, and the other end of the arc segment 322 elastically presses against the ear shell 210. This structure can increase the connection strength between each elastic arm 32 and the balance block 31, ensure that the elastic arm 32 is always pressed against the inner side of the ear shell 210, and prevent the ear shell 210 from shaking.

[0072] Preferably, in this embodiment, an arc-shaped protrusion 3221 close to the auricle 210 is provided at the free end of the arc-shaped segment 322 . Since the balance frame 3 is made of soft rubber, this design can increase the force and effect of the elastic support arm 32 and the auricle 210 .

[0073] In a preferred embodiment of the present invention, Figure 2 , 4 As shown in 11-12, the resistance pad 2 includes a gasket 21 and an annular spring piece 22, and the gasket 21 and the annular spring piece 22 are integrally formed by injection molding, wherein the material of the gasket 21 is preferably ABS, and is formed by two-color injection molding, and the annular spring piece 22 is preferably silicone, and the annular spring piece 22 elastically presses against the outer side of the ear shell 210 to increase the resistance to the rotation of the ear shell 210 and enhance the hand feel. In addition, the annular spring piece 22 can also cooperate with the balance frame 3 to clamp the inside and outside of the ear shell 210 at the same time to prevent shaking during its rotation, and can keep the ear shell 210 at a set angle after the external force is removed.

[0074] In addition, the gasket 21 is connected to the arm assembly 100, and the arm assembly 100 is provided with a step groove 101 for installing the gasket 21, and the gasket 21 is provided with a step 211 corresponding to the step groove 101, and the step 211 is inserted into the step groove 101 to achieve the fixation of the gasket 21 and the arm lower cover 102. In addition, in the present application, the gasket 21 includes an annular portion, and the inner circumference of the annular portion is recessed toward the arm lower cover 102 to adapt to the first groove 2103 recessed outwardly of the ear shell 210, thereby increasing the space behind the speaker 62 and achieving the effect of improving the sound quality.

[0075] In addition, the outer periphery of the annular spring piece 22 is fixed to the inner periphery of the gasket 21, and the inner periphery of the annular spring piece 22 extends toward the ear shell 210. The inner side of the annular spring piece 22 is provided with serrations 221, which can not only support the ear shell 210, but also increase the friction resistance between the annular spring piece 22 and the ear shell 210, thereby increasing the rotation feel of the ear shell 210.

[0076] An embodiment of the present invention provides a headset, such as Figure 1-2 The headset shown includes: the headset includes an earmuff rotating mechanism, an arm assembly 100, an ear shell assembly 200 and a headband 300, both ends of the headband 300 are connected to the arm assembly 100 respectively, and the arm assembly 100 and the headband 300 are retractably connected. Figure 1 As shown, the ear shell component 200, the arm component 100 and the ear shell component 200 correspond one to one, and the two arm components 100 are symmetrically connected at both ends of the headband 300. Each arm component 100 can perform telescopic movement relative to the headband 300. Specifically, a telescopic mechanism that enables the arm component 100 to be telescopic can be set between the headband 300 and the arm component 100. For example, the headband 300 is provided with a limited position slide, and the arm component 100 is connected with a slider that matches the limited position slide, and the slider slides along the limited position slide to achieve the telescopic movement of the arm component 100. Other structures that can achieve telescopic movement are also possible, and this application does not limit this, as long as the earmuffs 220 can meet the use requirements of different head shapes. Because the headset includes any of the above-mentioned earmuff rotation mechanisms, the headset of this embodiment also has the above-mentioned technical effects. That is to say, the earmuffs 220 of this embodiment can not only rotate 360 ​​degrees to meet the angle requirements of different users, but can also be extended and retracted along with the arm assembly 100 to meet the needs of different head shapes, thereby improving the wearing comfort and user experience through all-round adjustment.

[0077] In a preferred embodiment of the present invention, Figure 2-5The headphones shown also include electronic components 5 and a speaker assembly 6. The arm assembly 100 includes an arm lower cover 102 and an arm upper cover 103. The arm lower cover 102 and the arm upper cover 103 are arranged to form a first mounting cavity 104 for mounting the electronic components 5. The ear shell 210 forms a second mounting cavity 2104 with an opening. The earmuff 220 is connected to the opening of the ear shell 210. The speaker assembly 6 is mounted in the second mounting cavity 2104. The first mounting cavity 104 and the second mounting cavity 2104 are independent of each other. In the present application, the electronic components 5 include PCBA, batteries and other components, mainly for the prior art, where the PCBA, batteries and the like are in the same cavity as the speaker 62, and the shape is irregular, making it difficult to adjust the sound quality; the space of the rear cavity of the speaker 62 is small, and the airtight cavity is easy to cause irreversible deformation of the speaker diaphragm. The electronic components 5 and the speaker assembly 6 are respectively arranged in two independent cavities, so that the speaker assembly 6 is located alone in the second installation cavity 2104 with an opening, and the ear shell 210 is away from the opening. The side (located on the side behind the speaker 62) is concave outward to form a first groove 2103, so that there is a larger space behind the speaker 62. The structure of improving the sound quality through an independent sound cavity makes the speaker 62 achieve better sound quality, and can also prevent the speaker diaphragm from deforming. The earmuffs 220 can make the speaker 62 have better airtightness during playback, and can also reduce external noise interference, improve the noise reduction depth, and enhance the user experience.

[0078] In a preferred embodiment of the present invention, Figure 2-5 The speaker assembly 6 shown includes a speaker cover 61, a speaker 62 and a speaker pad 63 which are sequentially arranged from the inside to the outside. The speaker 62 is connected to the electronic component 5 through a speaker wire, wherein the balance screw 4 is provided with a wire hole 41 for the speaker wire to pass through in the axial direction. Since the balance screw 4 is fixedly connected to the rotating member 1 on the lower cover 102 of the support arm, the ear shell 210 always rotates around the central axis of the balance screw 4 and the rotating block 11 during the rotation process. The speaker wire sequentially passes through the wire hole 41, the threaded hole 121 and the through hole on the lower cover 102 of the support arm to enter the first installation cavity 104. The speaker wire does not need to rotate with the ear shell 210 and will not bend, deform or have other problems, thereby improving the service life of the speaker 62.

[0079] The present application utilizes the fact that the balance frame 3 is made of plastic material with a certain toughness and cleverly combines it into the headphone; the specific assembly steps are: first, the PCBA, battery and other components installed in the first installation cavity 104 are connected to the lower cover 102 and the upper cover 103 of the arm according to the steps, and the speaker wire is successively passed through the lead hole 41, the threaded hole 121 and the through hole on the lower cover 102 of the arm to introduce into the first installation cavity 104 and connected to the circuit board; then, the lower cover 102 and the upper cover 103 of the arm are fixed, the resistance pad 2 is fixed to the lower cover 102 of the arm, the ear shell 210 is sleeved on the rotating block 11, the balance frame 3 is installed inside the ear shell 210, the balance screw 4 passes through the second through hole 313 and is threadedly connected to the rotating column 12 and the balance screw 4 is tightened; finally, the speaker cover 61, the speaker 62 and the speaker pad 63 and the earmuff 220 are assembled in sequence. The speaker cover 61 and the ear shell 210 are sealed with glue, and the speaker pad 63 is connected to the ear shell 210 and fixed to the earmuff 220 through 3M glue.

[0080] In the embodiments of the present invention, the term "plurality" refers to two or more than two, unless otherwise clearly defined.
