[0048] With the development of wearable devices, headphones are gaining popularity among consumers due to their excellent sound quality and sound isolation. Headphones consist of a mounting bracket for the earmuffs and a headband. To accommodate different head shapes, the mounting bracket and headband are often rotatably connected. This allows the earmuffs to rotate to fit the ear area, achieving better sound isolation.

[0049] However, in the prior art, the rotational connection between the mounting bracket and the headband structure is too loose, resulting in reduced wearing stability of the headphones. The earmuffs cannot be fixed in the consumer's ear area, causing the headphones to easily slip or shift during wearing, affecting the wearing stability and comfort.

[0050] In order to solve the above problems, the first embodiment of the present application proposes an earphone support assembly, which includes a headband structure 100 and a mounting bracket 200 arranged at the end of the headband structure 100. Figures 1 to 5 As shown, the headband structure 100 is designed in an arc shape, and is connected to a mounting bracket 200 at each end. The mounting bracket 200 is used to mount the earmuff 300, and the earmuff 300 carries the sound unit.

[0051] Either one of the headband structure 100 and the mounting bracket 200 is fixedly provided with a rotating shaft 110, and the other is provided with a first accommodating cavity 201 and a fixing member 210. Figure 2 and Figure 3 In the embodiment shown, the rotating shaft 110 is fixedly provided at the end of the headband structure 100 and protrudes from the outer wall surface of the headband structure 100. The mounting bracket 200 is provided with a first accommodating cavity 201 and a first through hole 202 communicating with the first accommodating cavity 201 (see FIG. Figure 8 ), the rotating shaft 110 passes through the first through hole 202 and is inserted into the first accommodating chamber 201. The fixing member 210 is disposed in the first accommodating chamber 201 and is connected to the rotating shaft 110. Since the outer diameter of the fixing member 210 is larger than the inner diameter of the first opening 212, the rotating shaft 110 cannot be detached from the first accommodating chamber 201. When the headband structure 100 rotates relative to the mounting bracket 200, the rotating shaft 110 and the fixing member 210 rotate relative to each other in the first accommodating chamber 201. It is understandable that in other embodiments, the rotating shaft 110 can also be fixedly disposed on the mounting bracket 200, so as to achieve a rotatable connection between the mounting bracket 200 and the headband structure 100.

[0052] It should be noted that if Figure 6 and Figure 7 As shown, the cavity wall of the first accommodating cavity 201 is provided with a plurality of circumferentially distributed locking grooves 204, the rotating shaft 110 or the fixing member 210 is connected to the limiting clamping member 220, and the limiting clamping member 220 can rotate synchronously with the rotating shaft 110 and the fixing member 210, thereby realizing the locking connection between the limiting clamping member 220 and different locking grooves 204. Figure 7 In the embodiment shown, the positioning grooves 204 are evenly distributed along the circumference on the cavity wall of the first accommodating cavity 201 , and the groove walls of each positioning groove 204 are smoothly connected to facilitate the abutment and switching between the limiting clamp 220 and the groove walls of each positioning groove 204 .

[0053] Specifically, in the initial state, the position-limiting clip 220 is embedded in any one of the locking grooves 204. As the mounting bracket 200 and the headband structure 100 rotate relative to each other, the position-limiting clip 220 rotates relative to the wall of the first accommodating cavity 201, thereby moving the position-limiting clip 220 from one locking groove 204 to another. When the mounting bracket 200 and the headband structure 100 are rotated into position, the position-limiting clip 220 engages with the locking groove 204 and restricts the rotation of the mounting bracket 200 and the headband structure 100. It should be noted that the position-limiting clip 220 and the locking groove 204 serve to stop the mounting bracket 200 and the headband structure 100 before and after rotation, but do not hinder the rotation of the mounting bracket 200 and the headband structure 100 during adjustment.

[0054] When the earphone support assembly of the embodiment of the first aspect of the present application is applied to a headset, the consumer can hold the headband structure 100 and rotate the earmuff 300 so that the mounting bracket 200 rotates relative to the headband structure 100 to adjust the fit between the earmuff 300 and the face. Alternatively, when the headset is worn on the head, the earmuff 300 can automatically rotate according to the head shape to fit. During the rotation process, the limiting clamp 220 switches between different clamping grooves 204 to provide different fitting angles and fitting pressures for consumers to choose from, so that consumers with different head shapes and different pressure requirements can find a comfortable gear. Due to the cooperation between the limiting clamp 220 and the clamping groove 204, the rotation of the mounting bracket 200 can have a certain damping feeling and intermittent pause feeling, thereby having a good gear switching feel and clear gear switching feedback. The entire switching feel is relatively tight and feels more advanced.

[0055] After the mounting bracket 200 and the headband structure 100 are rotated into place, they are restricted by the limiting clamp 220 and the locking groove 204 and cannot be easily rotated, thereby reducing the possibility of the earphones slipping or shifting during wearing and improving the wearing stability and comfort.

[0056] In some embodiments, the limiting card 220 includes an elastic portion 222 and a plug portion 221, and one end of the elastic portion 222 is connected to either the rotating shaft 110 or the fixing member 210. That is, the limiting card 220 can be set on the rotating shaft 110 or on the fixing member 210. For example, Figure 6 and Figure 7 In the embodiment shown, it should be noted that Figure 7 for Figure 6Another assembly view from another angle, in which the fixing member 210 is hidden. The limiting clamp 220 is disposed on the fixing member 210. The other end of the elastic portion 222 is connected to the plug-in portion 221. When the rotating shaft 110 rotates relative to the cavity wall of the first accommodating cavity 201, the limiting clamp 220 abuts against the groove wall of the current locking groove 204 and, guided by the groove wall, gradually withdraws from the current locking groove 204. At the same time, the elastic portion 222 undergoes elastic deformation to accumulate elastic potential energy. After the limiting clamp 220 withdraws from the current locking groove 204, as the rotating shaft 110 further rotates, the limiting clamp 220 moves to the position corresponding to the next locking groove 204. The reaction force of the groove wall of the locking groove 204 on the limiting clamp 220 disappears, and the elastic portion 222 elastically deforms and resets, driving the plug-in portion 221 to insert into the locking groove 204.

[0057] Depending on the degree of rotation of the mounting bracket 200, the limit clamp 220 may stop moving further after moving into an adjacent locking groove 204, or the limit clamp 220 may continue to cycle the above process and stop moving after passing through multiple locking grooves 204 in sequence.

[0058] Furthermore, the position limiting member 220 has various implementations, for example, Figure 6 As shown, the plug-in portion 221 and the elastic portion 222 are integrally injection-molded, and an elastic portion 222 is connected to each side of the plug-in portion 221, forming a triangular structure with an opening. The plug-in portion 221, as the vertex of the triangular structure, transmits pressure to the elastic portions 222 on both sides when under pressure, causing the elastic force arms on both sides (i.e., the elastic portions 222) to bend and deform, thereby retracting the plug-in portion 221 toward the central axis of the rotating shaft 110, so that the limiting clamp 220 can withdraw from the current locking groove 204. It is understandable that when the limiting clamp 220 moves to the next locking groove 204, the elastic force arms on both sides resume elastic deformation to drive the plug-in portion 221 to extend in a direction away from the central axis of the rotating shaft 110, thereby inserting it into the locking groove 204.

[0059] Furthermore, the limiting clamp 220 is connected to the fixing member 210. The fixing member 210 is provided with at least one set of limiting grooves 211, and the number of the limiting grooves 211 is determined by the number of the limiting clamps 220. Figure 6 In the embodiment shown, the earphone support assembly includes three limiting clamps 220, so that three groups of limiting slots 211 are provided on the fixing member 210. Each group of limiting slots 211 includes two limiting slots 211, and the two limiting slots 211 in the same group have first openings 212 arranged opposite to each other. The end of the elastic portion 222 away from the plug-in portion 221 is inserted into the limiting slot 211 through the first opening 212 to limit the movement of the limiting clamp 220. Figure 6As shown, both ends of the limit card 220 are inserted into the limit slots 211 of the same group, realizing a detachable connection between the limit card 220 and the fixing member 210, and the design of this clamping structure is conducive to the rapid disassembly and assembly of the limit card 220 and the fixing member 210, which can improve assembly efficiency.

[0060] This application also proposes another embodiment of a position-limiting latch 220 (not shown): the elastic portion 222 and the plug portion 221 are made of different materials. The elastic portion 222 is a spring, and the plug portion 221 can be a plastic block or a metal block. The spring extends radially along the rotating shaft 110. The rotating shaft 110 has a groove for accommodating the spring. The spring is located in the groove, with one end connected to the plug portion 221 and the other end abutting the rotating shaft 110. When the plug portion 221 is not under pressure, part of the plug portion 221 is located in the groove, while part of the plug portion 221 protrudes from the outer periphery of the rotating shaft 110 and is embedded in the locking groove 204. When the plug portion 221 is under pressure, it is guided by the groove wall and moves back into the groove, compressing the spring and causing it to deform. When the pressure on the plug portion 221 is released, the spring recovers its elastic deformation, driving the plug portion 221 out of the groove.

[0061] In some embodiments, as Figures 1 to 5 As shown, the shaft 110 is fixedly connected to the headband structure 100 and is rotatably connected to the mounting bracket 200. The mounting bracket 200 defines a first accommodating cavity 201 and a first through hole 202 communicating with the first accommodating cavity 201. The shaft 110 is inserted into the first through hole 202 and inserted into the first accommodating cavity 201. Figure 8 and Figure 10 As shown, the outer peripheral wall of the rotating shaft 110 is provided with a first protrusion 111, and the edge position of the first through hole 202 on the mounting bracket 200 is provided with a first groove 203. The first groove 203 extends along the circumference of the first through hole 202. When the mounting bracket 200 rotates relative to the headband structure 100, the first protrusion 111 slides in the first groove 203. Figure 8 As shown, the first groove 203 is an arc-shaped groove with a certain arc length, thus having a starting position and an ending position. When the first protrusion 111 moves from the starting position to the ending position, or vice versa, within the first groove 203, the first protrusion 111 abuts against the groove wall of the first groove 203, thereby limiting further rotation of the rotating shaft 110. Thus, the cooperation between the first groove 203 and the first protrusion 111 limits the rotation range of the mounting bracket 200 relative to the headband structure 100. It will be appreciated that the size of this rotation range (i.e., the length of the first groove 203) can be designed based on the head sizes of different consumer groups.

[0062] Further, such as Figure 10 As shown, the outer wall of the rotating shaft 110 is further provided with a second protrusion 112. The number of the second protrusions 112 can be two as shown, or one, three, or other numbers. The headband structure 100 is provided with a second accommodating cavity 101 for accommodating a portion of the rotating shaft 110. The cavity wall of the second accommodating cavity 101 defines a second groove 102. The second protrusion 112 is inserted into the second groove 102 and abuts against the groove wall of the second groove 102 to limit the rotation of the rotating shaft 110 relative to the headband structure 100.

[0063] In some embodiments, as Figures 1 to 5 As shown, the mounting bracket 200 is an arc-shaped structure. One end of the mounting bracket 200 is rotatably connected to the headband structure 100, and the other end is used to connect to the earmuff 300. It should be noted that the mounting bracket 200 and the earmuff 300 are also rotatably connected. Therefore, the earmuff 300 can be rotated in addition to the following operations. Figure 1 The upward and downward rotation adjustment shown in FIG. Figure 1 The left-right rotation adjustment shown provides multiple degrees of adjustment freedom to better fit the consumer's head shape. It is understood that the rotatable connection structure between the mounting bracket 200 and the earmuff 300 can be the same as the rotatable connection structure between the mounting bracket 200 and the headband structure 100, or the rotatable connection structure between the mounting bracket 200 and the earmuff 300 can be other methods.

[0064] In some embodiments, the mounting bracket 200 includes a main body 230 and a decorative member 240. Figure 9As shown, the main body 230 defines a receiving groove 231 and a wiring groove 232 communicating with the receiving groove 231. The wiring groove 232 extends along the length of the main body 230, forming a thin-walled structure with a single-side opening. The walls of both the receiving groove 231 and the wiring groove 232 are provided with a snap-fit ​​groove 233, and the decorative member 240 is provided with a snap-fit ​​protrusion 241. Therefore, during the assembly process of the decorative member 240 and the main body 230, the thin-walled structure of the main body 230 can be slightly deformed, allowing the decorative member 240 to be snapped between the two side walls of the main body 230, and the snap-fit ​​protrusion 241 and the snap-fit ​​groove 233 to snap into place. Furthermore, the decorative member 240 covers the receiving groove 231 and the wiring groove 232, making its interior relatively closed. It should be noted that the bottom of the accommodating groove 231 is provided with a first through-hole 202 and the top is open. The fixing member 210 can be installed into the accommodating groove 231 through this open opening and fixedly connected to the rotating shaft 110. When the decorative member 240 is engaged with the main member 230, the top of the accommodating groove 231 is sealed, and the decorative member 240 and the main member 230 jointly define the first accommodating cavity 201. The top of the wiring groove 232 is also sealed, and the decorative member 240 and the main member 230 jointly define a wiring channel.

[0065] The second embodiment of the present application provides a headset, such as Figures 1 to 3 As shown, the headset includes earmuffs 300 and the headset bracket assembly mentioned in any of the above embodiments. The earmuffs 300 are connected to the headband structure 100 via the mounting bracket 200. The rotation adjustment structure of the headset is relatively compact, which can ensure a close fit to the face while reducing the probability of the headset slipping off, and can provide consumers with a better user experience.

[0066] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various modifications can be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. In addition, the embodiments of the present invention and the features of the embodiments can be combined with each other unless there is a conflict.
