earphone

Abstract

The earphone is disclosed in the embodiment of the present application, a rotating piece is rotatably connected with a shell piece, when a wearer adjusts the wearing angle through the hanging ear part, the wearer can further adjust the orientation of the sound outlet by rotating the rotating piece, thereby improving the listening experience of the wearer. Thus, on the one hand, the wearer drives the second rotation stopping area away from the first rotation stopping area by pressing the first pressing piece to make the first rotation stopping structure separate, and drives the first rotation stopping structure to reset again through the first elastic body, which can ensure that the sound outlet stays at a specific angle, avoids easy rotation of the sound outlet when wearing, and simplifies the adjustment mode of the wearer. On the other hand, when the wearing angle of the earphone is changed through the hanging ear part, the rotating piece can cooperate to adjust the direction of the sound outlet, which can reduce the discomfort of the wearer when the earphone is worn for a long time under the premise of ensuring the audio quality. Meanwhile, the wearer can also adjust the distance between the sound generating part and the ear hole according to different use scenarios.

Description

Technical Field

[0001] This invention relates to the field of electroacoustic conversion technology, and more particularly to an earphone. Background Technology

[0002] When worn, over-ear headphones are secured to the ear with the over-ear structure, allowing the headphone body to be close to the ear canal for sound output. When the wearing angle of the headphones changes, the distance and position between the sound outlet and the ear canal also change, directly affecting the headphone's audio quality. Therefore, ensuring a comfortable listening experience for the wearer when the wearing angle changes is a problem that needs to be solved. Summary of the Invention

[0003] In view of this, embodiments of the present invention provide an earphone that utilizes a first anti-rotation structure to allow the sound outlet to face a specific position in order to ensure the wearer's listening experience.

[0004] The earphones of this embodiment of the invention include: Ear loops; and The sound-emitting part is disposed on the ear hook and includes a rotating part, a shell, a first elastic body, a fixing frame and a first pressing part. The rotating part has a sound outlet and a first anti-rotation area, and the fixing frame has a second anti-rotation area. The rotating part is rotatably connected to the shell. The first elastic body, the fixing frame and the first pressing part are disposed on the shell. The elastic force generated by the first elastic body drives the second anti-rotation area to approach the first anti-rotation area. The second anti-rotation area abuts against the first anti-rotation area and forms a first anti-rotation structure. The first pressing member moves inward toward the inside of the shell to move the second anti-rotation zone away from the first anti-rotation zone, and the first elastic body undergoes elastic deformation.

[0005] Furthermore, the housing has a first mating hole; The first pressing component includes a first pressing end, a first driving end, and a first connecting shaft. The first connecting shaft is connected between the first pressing end and the first driving end. The first pressing end extends out from the first mating hole, the first driving end extends into the inner side of the housing and abuts against the fixing frame, and the first connecting shaft passes through the first mating hole.

[0006] Furthermore, the first driving end has a first guiding surface; The fixing bracket has a second guide surface that abuts against the first guide surface, and the side of the second guide surface near the rotating part is inclined away from the first mating hole; The first elastic body drives the second anti-rotation zone to approach the first anti-rotation zone, and the fixing bracket pushes against the first guide surface through the second guide surface and the first mating hole.

[0007] Furthermore, one of the rotating component and the housing component is provided with a first latch, and the other is provided with a sliding groove. The sliding groove extends along the rotation direction of the rotating component, and the first latch extends into the sliding groove. The rotating part rotates relative to the housing part, and the first latch slides along the groove.

[0008] Furthermore, the sound-generating part also includes a loudspeaker, which is disposed on the rotating part; The two ends of the chute have two stop surfaces, which are arranged opposite each other and spaced apart by a predetermined distance; The rotating component and the speaker rotate to a predetermined angle, and the first latch abuts against the stop surface.

[0009] Furthermore, the housing has a connection port for connecting with the rotating part, and two sliding grooves are formed on the inner wall of the housing, with the two sliding grooves arranged adjacent to the connection port; The number of first latches is two and they are respectively set to correspond to two slides. Each first latch has a guide slope and a third limiting surface. The third limiting surface is located on the side of the guide slope close to the rotating part. In the radial direction of the rotating part, the two guide slopes correspond to the edges of the two connecting ports.

[0010] Furthermore, the rotating component includes an adapter ring and an ear cap, with a first latch disposed on the adapter ring and the ear cap fixedly connected to the adapter ring; The ear cap includes a mouthpiece and a groove. The speaker is fixedly connected to the ear cap, and the speaker diaphragm and the groove form a sound chamber. The mouthpiece extends laterally toward the adapter ring and forms a sound outlet that communicates with the sound chamber.

[0011] Furthermore, the mounting bracket has a first guide ring surface; The ear cap has multiple retaining slots; The adapter ring has a second guide ring surface and multiple second latches corresponding to multiple fixing slots. The second latches are engaged in the corresponding fixing slots. The second anti-rotation zone is close to or far from the first anti-rotation zone. The first guide ring surface slides along the second guide ring surface.

[0012] Furthermore, the housing has a second mating hole, and the fixing bracket has a first clearance hole and a second clearance hole. The first clearance hole corresponds to the first mating hole, and the second clearance hole corresponds to the second mating hole. The first connecting shaft passes through the first clearance hole. The sound-generating part also includes a second connecting shaft, which passes through a second mating hole and a second clearance hole, and the central axis of the second connecting shaft is collinear with the central axis of the first connecting shaft.

[0013] Furthermore, the first elastic body is a compression spring, one end of which abuts against the side of the fixed frame away from the rotating part, and the elastic force at the other end acts on the shell.

[0014] Furthermore, one end of the first connecting shaft is connected to the first pressing end and its outer diameter is smaller than that of the first pressing end; The sound-generating part also includes a retaining ring, which has an installation notch. The retaining ring is located on the side of the first clearance hole away from the first pressing end, and the first connecting shaft passes through the retaining ring. The first elastic body drives the fixing frame to push the first pressing end against the first clearance hole until the retaining ring abuts between the end face of the first pressing end and the edge of the first clearance hole.

[0015] Furthermore, the first anti-rotation zone includes multiple first limiting teeth; The second anti-rotation zone includes multiple second limiting teeth, and multiple first limiting teeth and multiple second limiting teeth are arranged sequentially along the rotation direction of the rotating component; The first limiting tooth is engaged between multiple second limiting teeth and forms the first anti-rotation structure.

[0016] Furthermore, the ear loops also include: A fixed arm, which bends and extends along a first plane to form a lug area, has a first connecting end; and A transition piece is connected to the sound-emitting part and has a second connection end, wherein the first connection end and the second connection end have a first connection state and a second connection state; The sound-emitting part includes a loudspeaker. In a first connection state, the diaphragm of the loudspeaker faces one side of the first plane, and in a second connection state, the diaphragm of the loudspeaker faces the other side of the first plane.

[0017] The headphones of this invention rotatably connect the rotating component to the shell. When the wearer adjusts the wearing angle via the ear hook, the wearer can further adjust the orientation of the sound outlet by rotating the rotating component, improving the wearer's listening experience. Thus, on one hand, by pressing the first pressing component to drive the second anti-rotation area away from the first anti-rotation area, causing the first anti-rotation structure to separate, and then by driving the first elastic body to reset the first anti-rotation structure, the sound outlet can be kept at a specific angle, preventing it from easily rotating during wear, while simplifying the wearer's adjustment method. On the other hand, when changing the wearing angle of the headphones via the ear hook, the rotating component can adjust the direction of the sound outlet, reducing wearer discomfort during prolonged wear while ensuring audio quality. Simultaneously, the wearer can also adjust the distance between the sound-emitting part and the ear canal according to different usage scenarios. Attached Figure Description

Detailed Implementation

[0020] The present invention is described below based on embodiments, but the invention is not limited to these embodiments. In the detailed description of the invention below, certain specific details are described in detail. Those skilled in the art will fully understand the invention even without these details. To avoid obscuring the essence of the invention, well-known methods, processes, flows, elements, and circuits are not described in detail.

[0021] Furthermore, those skilled in the art should understand that the accompanying drawings provided herein are for illustrative purposes only and are not necessarily drawn to scale.

[0022] Unless the context explicitly requires it, words such as "including" or "contains" throughout the application should be interpreted as including rather than exclusive or exhaustive; that is, meaning "including but not limited to".

[0023] In the description of this invention, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0024] Unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0025] For ease of explanation, spatially related terms such as “inside,” “outside,” “below,” “below,” “lower,” “above,” “upper,” etc., are used herein to describe the relationship between one element or feature illustrated in the figure and another. It will be understood that spatially related terms may be intended to encompass different orientations of the device in use or operation besides those depicted in the figure. For example, if the device in the figure is flipped, an element described as “below” or “below” another element or feature would then be positioned “above” that other element or feature. Thus, the exemplified term “below” can encompass both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially related descriptive terms used herein should be interpreted accordingly.

[0026] Figure 1 This is a schematic diagram of the first wearing state of the headphones in this embodiment. Figure 2 This is a schematic diagram of the second wearing state of the headphones in this embodiment. Figure 3 and Figure 4 This is a schematic diagram of the structure of the earphone provided in this embodiment.

[0027] In some implementations, such as Figures 1-4 As shown, the headphones include a sound-emitting part 1 and an ear hook 2. The ear hook 2 is curved and hangs on the ear. The sound-emitting part 1 has a sound outlet 181. The wearer can adjust the position of the ear hook 2 on the ear to change the wearing state of the headphones. The headphones in this embodiment have multiple wearing states. Taking the headphones worn on the left ear as an example, in the second wearing state, the sound-emitting part 1 is closer to the ear canal A2, and the second wearing state is rotated towards the wearer's rear side relative to the first wearing state.

[0028] Figures 5-15 The specific structure of the headphones provided in the first embodiment is shown. Figures 16-20 The specific structure of the headphones provided in the second embodiment is shown.

[0029] Further reference Figures 7-10 and Figures 19-20 As shown, the sound-emitting part 1 is disposed on the ear hook part 2. The sound-emitting part 1 includes a rotating member 18, a housing 11, a first elastic body 122, a fixing frame 15, and a first pressing member 16. The rotating member 18 has a sound outlet 181 and a first anti-rotation area 182. The fixing frame 15 has a second anti-rotation area 156. The rotating member 18 is rotatably connected to the housing 11. The first elastic body 122, the fixing frame 15, and the first pressing member 16 are disposed on the housing 11. The elastic force generated by the first elastic body 122 drives the second anti-rotation area 156 to approach the first anti-rotation area 182. The second anti-rotation area 156 abuts against the first anti-rotation area 182 and forms a first anti-rotation structure (e.g., ...). Figure 20 (As indicated by arrow a5 in the image). Further refer to... Figure 11As shown, the first pressing member 16 moves inward toward the inside of the housing 11 (as indicated by arrow a4 in the figure) to drive the second anti-rotation zone 156 away from the first anti-rotation zone 182 (as shown in the figure). Figure 19 and Figure 21 As indicated by arrow a6 in the diagram, the first elastic body 122 undergoes elastic deformation, causing... Figure 21 The distance L1 in the middle decreases.

[0030] Optionally, such as Figure 2 As shown, the rotating member 18 has a third rotation direction (as indicated by arrow a8 in the figure) and a fourth rotation direction (as indicated by arrow a9 in the figure). In the first wearing state, the sound outlet 181 faces the rear side of the concha A1. In the second wearing state, the wearer can press the first pressing member 16 and rotate the rotating member 18 in the third rotation direction (counterclockwise) so that the sound outlet 181 remains facing the rear side of the concha A1, thereby improving the listening effect. In the second wearing state, the wearer can also rotate the sound outlet 181 in the fourth rotation direction (clockwise) so that it faces the ear canal A2, thereby switching the headphones from open-back to semi-open-back.

[0031] In summary, the headphones of this embodiment rotatably connect the rotating member 18 to the shell 11. When the wearer adjusts the wearing angle via the ear hook 2, the wearer can further adjust the orientation of the sound outlet 181 by rotating the rotating member 18, thus improving the wearer's listening experience. Therefore, on the one hand, by pressing the first pressing member 16 to drive the second anti-rotation zone 156 away from the first anti-rotation zone 182 to separate the first anti-rotation structure, and by driving the first anti-rotation structure back to its original position via the first elastic body 122, the sound outlet 181 can be kept at a specific angle, preventing it from easily rotating during wear, and simplifying the wearer's adjustment method. On the other hand, when changing the wearing angle of the headphones via the ear hook 2, the rotating member 18 can adjust the direction of the sound outlet 181, reducing the wearer's discomfort during prolonged wear while ensuring audio quality. Simultaneously, the wearer can also adjust the distance between the sound-emitting part 1 and the ear canal A2 according to different usage scenarios.

[0032] In some implementations, such as Figures 7-10As shown, the housing 11 has a first mating hole 112. The first pressing member 16 includes a first pressing end 162, a first driving end 163, and a first connecting shaft 161. The first connecting shaft 161 is connected between the first pressing end 162 and the first driving end 163. The first pressing end 162 extends out of the first mating hole 112, the first driving end 163 extends into the inside of the housing 11 and abuts against the fixing frame 15, and the first connecting shaft 161 passes through the first mating hole 112. In this embodiment, the first pressing member 16 is connected between the housing 11 and the fixing frame 15, so that the first pressing member 16 can move linearly relative to the housing 11. When the wearer wears the headphones, they can directly press the first pressing end 162 to separate the first anti-rotation structure. When the sound outlet 181 rotates to a suitable angle, the wearer can release the first pressing end 162 to achieve self-locking through the first elastic body 122 and the first anti-rotation structure.

[0033] In some implementations, such as Figures 7-9 As shown, the first drive end 163 has a first guide surface 1631. The fixing frame 15 has a second guide surface 157 that abuts against the first guide surface 1631, and the side of the second guide surface 157 near the rotating member 18 is inclined away from the first mating hole 112. During the process of the first elastic body 122 driving the second anti-rotation zone 156 to approach the first anti-rotation zone 182, the fixing frame 15 pushes the first guide surface 1631 against the first mating hole 112 through the second guide surface 157.

[0034] Specifically, the movement direction of the fixing frame 15 is perpendicular to the movement direction of the first pressing member 16. The first guide surface 1631 and the second guide surface 157 are both inclined at 45 degrees to convert the movement of the first pressing member 16 into the movement of the fixing frame 15, and also to make the contact between the fixing frame 15 and the first pressing member 16 smoother.

[0035] In some implementations, such as Figures 7-8 As shown, one of the rotating member 18 and the housing member 11 is provided with a first latch 183, and the other is provided with a sliding groove 114. The sliding groove 114 extends along the rotation direction of the rotating member 18, and the first latch 183 extends into the sliding groove 114. When the rotating member 18 rotates relative to the housing member 11, the first latch 183 slides along the sliding groove 114. In this embodiment, the first latch 183 and the sliding groove 114 can prevent the first anti-rotation zone 182 from being pushed out by the second anti-rotation zone 156, while also providing rotational freedom for the rotating member 18.

[0036] In some implementations, such as Figure 12 As shown, the sound-emitting part 1 also includes a speaker 17, which is disposed on the rotating member 18. Further referencing... Figure 8As shown, the slide groove 114 has two stop surfaces 1141 at both ends, which are arranged opposite each other and spaced apart by a predetermined distance. When the rotating member 18 and the speaker 17 rotate by a predetermined angle, the first latch 183 abuts against the stop surface 1141. In this embodiment, the speaker 17 rotates together with the rotating member 18. When the rotation amplitude of the rotating member 18 is too large, the cable connected to the speaker 17 is prone to twisting or tangling. Therefore, the two stop surfaces 1141 in this embodiment can effectively limit the rotation amplitude of the rotating member 18 to avoid excessive rotation of the rotating member 18.

[0037] In some implementations, such as Figures 8-9 As shown, the housing 11 has a connection port 115 for connection with the rotating member 18, and two sliding grooves 114 are formed on the inner wall of the housing 11, with the two sliding grooves 114 adjacent to the connection port 115. Further referencing... Figure 12 As shown, there are two first latches 183, which are respectively set to correspond to two slides 114. Each first latch 183 has a guide slope 1832 and a third limiting surface 1831. The third limiting surface 1831 is located on the side of the guide slope 1832 close to the rotating member 18. In the radial direction of the rotating member 18, the two guide slopes 1832 correspond to the edges of the two connecting ports 115.

[0038] In this embodiment, when assembling the sound-generating part 1, the speaker 17 can be installed onto the rotating part 18 first, and then the rotating part 18 can be inserted into the slide groove 114 through the two first latches 183. During this process, the two guide slopes 1832 abut against the connection port 115, and the two first latches 183 bend and deform towards the inside of the rotating part 18, so that the two first latches 183 can enter the inside of the shell 11 until the two third limiting surfaces 1831 are placed on the inner wall of the slide groove 114, thereby simplifying the assembly process of the sound-generating part 1.

[0039] In some implementations, such as Figure 12 As shown, the rotating component 18 includes a connecting ring 184 and an ear cap 185. A first latch 183 is disposed on the connecting ring 184, and the ear cap 185 is fixedly connected to the connecting ring 184. The ear cap 185 includes a mouthpiece 1851 and a groove 1852. The speaker 17 is fixedly connected to the ear cap 185, and the diaphragm of the speaker 17 and the groove 1852 form a sound chamber. The mouthpiece 1851 extends laterally towards the connecting ring 184 and forms a sound outlet 181 communicating with the sound chamber. In this embodiment, during the rotation of the rotating component 18, the connecting ring 184 and the ear cap 185 rotate together, and the distance between the mouthpiece 1851 and the ear canal A2 can be adjusted during rotation. For example, when the mouthpiece 1851 faces the ear canal A2, the distance between the sound outlet 181 and the ear canal A2 is smaller, thereby reducing the impact of environmental noise on the audio.

[0040] In some implementations, such as Figures 8-9 and Figure 13 As shown, the mounting bracket 15 has a first guide ring surface 158. Further referencing... Figure 13 and Figure 20 As shown, the ear cap 185 has multiple fixing slots 1853. The adapter ring 184 has a second guide ring surface 1841 and multiple second latches 186 corresponding to the multiple fixing slots 1853. The second latches 186 are engaged in the corresponding fixing slots 1853. As the second anti-rotation zone 156 moves closer to or further away from the first anti-rotation zone 182, the first guide ring surface 158 slides along the second guide ring surface 1841. In this embodiment, the second latches 186 can also be engaged with the ear cap 185 in the above manner. At the same time, the cooperation of the first guide ring surface 158 and the second guide ring surface 1841 allows the fixing frame 15 to move along the axial direction of the adapter ring 184.

[0041] In some implementations, such as Figures 8-10 As shown, the housing 11 has a second mating hole 111. The mounting bracket 15 has a first clearance hole 154 and a second clearance hole 153. The first clearance hole 154 corresponds to the first mating hole 112, and the second clearance hole 153 corresponds to the second mating hole 111. The first connecting shaft 161 passes through the first clearance hole 154. The sound-generating part 1 also includes a second connecting shaft 143, which passes through the second mating hole 111 and the second clearance hole 153, and the central axis of the second connecting shaft 143 is parallel to the central axis of the first connecting shaft 161 (e.g., ...). Figure 8 (As indicated by mark I in the diagram) are collinear. In this embodiment, the sound-generating part 1 is rotatably mounted on the two connecting arms 24 via the first connecting shaft 161 and the second connecting shaft 143, respectively, which improves the stability of the connection between the sound-generating part 1 and the ear-hanging part 2. At the same time, the elastic force of the first elastic body 122 can act on the first connecting shaft 161 and the second connecting shaft 143 respectively, so that the elastic force is dispersed.

[0042] Specifically, such as Figures 9-10 As shown, both the first clearance hole 154 and the second clearance hole 153 are elongated holes, with their length direction parallel to the axial direction of the adapter ring 184. The widths of the two elongated holes are respectively adapted to the first connecting shaft 161 and the second connecting shaft 143. When the fixing frame 15 moves along the axial direction of the adapter ring 184, the first clearance hole 154 and the second clearance hole 153 can move radially along the first connecting shaft 161 and the second connecting shaft 143, respectively. At the same time, the first connecting shaft 161 and the second connecting shaft 143 can also guide the movement of the fixing frame 15.

[0043] In some implementations, such as Figure 19 As shown, the first elastic body 122 is a compression spring. One end of the compression spring abuts against the side of the fixed frame 15 away from the rotating member 18, and the elastic force of the other end acts on the shell member 11.

[0044] Specifically, the elastic force of the compression spring acts on the housing 11 through the locking member 3. Thus, the compression spring in this embodiment can provide a resisting force to the second anti-rotation zone 156, keeping the first anti-rotation structure in the contact state and preventing the rotating member 18 from rotating easily.

[0045] In some implementations, such as Figure 5 and Figures 8-9 As shown, one end of the first connecting shaft 161 is connected to the first pressing end 162, and its outer diameter is smaller than that of the first pressing end 162. The sound-generating part 1 also includes a retaining ring 19. The retaining ring 19 has a mounting notch 191, and the retaining ring 19 is disposed on the side of the first clearance hole 154 away from the first pressing end 162, and the first connecting shaft 161 passes through the retaining ring 19. The first elastic body 122 drives the fixing bracket 15 to push the first pressing end 162 against the first clearance hole 154 until the retaining ring 19 abuts between the end face of the first pressing end 162 and the edge of the first clearance hole 154.

[0046] In this embodiment, during the assembly of the sound-generating part 1, the fixing frame 15 can be first placed inside the housing 11, and the first elastic body 122 can be abutted between the fixing frame 15 and the locking member 3. Then, the first driving end 163 is passed through the first connecting hole 22, the first mating hole 112 and the first clearance hole 154 in sequence and abuts against the fixing frame 15. In this form, the mounting notch 191 of the retaining ring 19 faces the first pressing member 16, and the retaining ring 19 is locked between the first driving end 163 and the inner wall of the fixing frame 15, so as to simplify the assembly method of the sound-generating part 1.

[0047] In some implementations, such as Figures 17-20 As shown, the first anti-rotation zone 182 includes a plurality of first limiting teeth 1821. The second anti-rotation zone 156 includes a plurality of second limiting teeth 1561. The plurality of first limiting teeth 1821 and the plurality of second limiting teeth 1561 are arranged sequentially along the rotation direction of the rotating member 18. The first limiting teeth 1821 are engaged between the plurality of second limiting teeth 1561 to form a first anti-rotation structure. In this embodiment, the mutual engagement of the two sets of limiting teeth prevents the rotating member 18 from rotating easily.

[0048] Optionally, such as Figure 7 and Figure 8 As shown, the first anti-rotation zone 182 and the second anti-rotation zone 156 can also be configured as a convex structure or a corrugated structure, etc.

[0049] In some implementations, such as Figures 3-6 As shown, the ear-mounted part 2 also includes a fixing arm 25 and a transition member 26. The fixing arm 25 is along the first plane (e.g., Figure 14 and Figure 19(As shown by dashed line II in the diagram) bends and extends to form an ear-hook area 251, and the fixing arm 25 has a first connecting end 252. The transition member 26 includes two connecting arms 24, an intermediate body 23, and a first anti-rotation body 21. The transition member 26 is connected to the sound-emitting part 1 and has a second connecting end 231. The first connecting end 252 and the second connecting end 231 have a first connected state and a second connected state. The sound-emitting part 1 includes a loudspeaker 17. In the first connected state, the diaphragm of the loudspeaker 17 faces one side of the first plane (e.g., ...). Figure 1 (As shown). In the second connection state, the diaphragm of speaker 17 faces the other side of the first plane.

[0050] Specifically, one of the first connecting end 252 and the second connecting end 231 is a plug block, and the other is a plug slot. The plug block has two plugging directions (the two plugging directions are opposite) within the plug slot, so that the same sound-producing part 1 and ear hook part 2 can be assembled into headphones that are compatible with the left and right ears through two assembly methods. This further reduces material costs.

[0051] Furthermore, the movement directions of the first pressing end 162 and the second pressing end 141, the movement direction of the fixing frame 15, and the extension direction of the slide 151 are all perpendicular to each other. The first pressing end 162 and the second pressing end 141 face opposite directions, allowing the wearer to press both simultaneously. The first driving end 163 and the second driving end 142 move to opposite sides. In this configuration, the second anti-rotation body 131 moves away from the first anti-rotation body 21, and the second anti-rotation area 156 moves away from the first anti-rotation area 182. Simultaneously, the fixing frame 15 drives the limiting member 13 away from the rotating member 18. That is, the first pressing end 162 and the second pressing end 141 achieve synchronous separation of the two anti-rotation structures. This avoids interference between the second anti-rotation body 131 and the first anti-rotation body 21 caused by the fixing frame 15 driving the limiting member 13 to move when the second anti-rotation body 131 comes into contact with the first anti-rotation body 21.

[0052] In some implementations... Figures 5-11 As shown, the ear loop 2 includes a first anti-rotation body 21. The sound-generating part 1 and the ear loop 2 form a rotating pair. The sound-generating part 1 includes a housing 11, a second elastic body 121, a limiting member 13, and a second pressing member 14. The second elastic body 121, the limiting member 13, and the second pressing member 14 are disposed on the housing 11. The limiting member 13 includes a second anti-rotation body 131. Further referencing... Figure 14 and Figure 19As shown, the elastic force generated by the second elastic body 121 drives the second anti-rotation body 131 to approach the first anti-rotation body 21 (as shown in a1 in the figure), and the second anti-rotation body 131 abuts against the first anti-rotation body 21 to form a second anti-rotation structure. In this embodiment, the second anti-rotation structure can restrict the easy rotation of the sound-emitting part 1, so that the sound-emitting part 1 can be kept at different angles with the ear hook part 2 to adapt to the ear contours of different wearers.

[0053] Further reference Figure 11 , Figure 15 and Figure 20 As shown, the second pressing member 14 moves inward toward the inside of the housing member 11 (e.g.) Figure 11 (As shown by arrow a2 in the image) to move the second anti-rotation body 131 away from the first anti-rotation body 21 (as shown by arrow a2 in the image) Figure 15 and Figure 20 As indicated by arrow a3 in the diagram, the second elastic body 121 undergoes elastic deformation. In this embodiment, the limiting member 13 is moved away from the first anti-rotation body 21, allowing the sound-emitting part 1 to regain rotational freedom, so that the wearer can freely rotate the sound-emitting part 1.

[0054] Optionally, the sound-generating part 1 has a first rotation direction (e.g., Figure 14 (as shown) and the second rotation direction (as shown) Figure 19 (As shown). When the wearer stops pressing the second press member 14, the second elastic body 121 can push the second press member 14 through the limiting member 13, so that the limiting member 13 and the second press member 14 remain in contact.

[0055] Specifically, the headphones in this embodiment are configured as open-back headphones. In the first wearing state (e.g. Figure 1 As shown), the sound-producing part 1 is close to the concha cavity A1 and adjacent to the ear canal A2, with part of the sound-producing part 1 attached to the helix foot A4. The ear-hook part 2 passes through the top area of ​​the helix A3 and extends to the back side of the helix A3. In the second wearing state (such as... Figure 2 As shown), when the earphone is rotated clockwise, the sound-emitting part 1 is closer to the inner side of the concha A1. In this configuration, the wearer can press the second pressing member 14, causing the sound-emitting part 1 to rotate in the second direction (as shown). Figure 19 (As shown) rotate. This allows the sound-producing part 1 to move closer to the ear canal A2, optimizing the listening experience. Simultaneously, the contact position between the ear hook 2 and the helix A3 changes during this process, reducing discomfort during prolonged wear.

[0056] In summary, the headphones of this embodiment, through the rotating joint formed by the sound-emitting part 1 and the ear hook 2, allow the wearer to rotate the sound-emitting part 1 to adjust the relative angle between the ear hook 2 and the sound-emitting part 1, so that the headphones can fit the contour of the human ear more closely and improve wearing comfort. Thus, on the one hand, by pressing the second pressing member 14 to drive the second anti-rotation body 131 away from the first anti-rotation body 21 to separate the second anti-rotation structure, and by driving the second anti-rotation structure back to its original position through the second elastic body 121, the wearer can ensure that the sound-emitting part 1 remains at a specific angle, preventing it from easily rotating during wear, and simplifying the wearer's adjustment method. On the other hand, by changing the wearing angle of the headphones through the ear hook 2 and adjusting it in conjunction with the rotating joint, the wearer's discomfort is reduced during prolonged wear. Simultaneously, the wearer can also adjust the distance between the sound-emitting part 1 and the ear canal A2 according to different usage scenarios.

[0057] In some implementations, such as Figure 5 and Figure 8 As shown, the ear hook portion 2 includes a first connecting hole 22, and the housing 11 has a second mating hole 111. The second pressing member 14 includes a second pressing end 141, a second driving end 142, and a second connecting shaft 143, with the second connecting shaft 143 connecting between the second pressing end 141 and the second driving end 142. Further referencing... Figure 11 As shown, the second pressing end 141 extends to the side of the first connecting hole 22 away from the second mating hole 111, the second driving end 142 extends into the inside of the shell 11 and abuts against the limiting member 13, and the second connecting shaft 143 passes through the first connecting hole 22 and the second mating hole 111 to form a rotating pair with the shell 11 and the ear hook 2. In this embodiment, the second pressing member 14 is connected between the shell 11 and the ear hook 2, so that the sound-emitting part 1 can rotate relative to the ear hook 2 through the second pressing member 14. When wearing the headphones, the wearer can directly press the second pressing end 141 to adjust the wearing angle of the headphones. When the sound-emitting part 1 rotates to a suitable angle, the wearer can release the second pressing end 141 to achieve self-locking through the second elastic body 121 and the limiting member 13.

[0058] In some implementations, such as Figures 8-10 As shown, the second driving end 142 has a third guide surface 1421. The limiting member 13 has a fourth guide surface 132, which abuts against the third guide surface 1421. The side of the fourth guide surface 132 closest to the first anti-rotation body 21 is inclined away from the second mating hole 111. During the process of the second elastic body 121 driving the second anti-rotation body 131 closer to the lug portion 2, the limiting member 13 pushes the third guide surface 1421 against the first connecting hole 22 through the fourth guide surface 132.

[0059] Specifically, the movement direction of the limiting member 13 is perpendicular to the movement direction of the second pressing member 14, and the third guide surface 1421 and the fourth guide surface 132 are both inclined at 45 degrees, so as to convert the movement of the second pressing member 14 into the movement of the limiting member 13, and also make the contact between the limiting member 13 and the second pressing member 14 smoother.

[0060] In some implementations, such as Figures 6-7 and Figure 14 As shown, both the first anti-rotation body 21 and the second anti-rotation body 131 have friction textures 213. When the rotating pair rotates by a predetermined angle, the two friction textures 213 at least partially come into contact.

[0061] Optionally, the friction texture 213 can be a raised dot structure or a corrugated structure to increase the friction between the two friction textures 213. At the same time, the two friction textures 213 can be used to achieve stepless adjustment of the rotation angle of the sound-generating part 1.

[0062] In some implementations, such as Figures 17-20 As shown, the second anti-rotation structure includes a plurality of first positioning teeth 211 and at least one second positioning tooth 212. One of the second positioning tooth 212 and the first positioning tooth 211 is formed in the first anti-rotation body 21, and the other is formed in the second anti-rotation body 131. When the rotating joint rotates by a predetermined angle, the first positioning tooth 211 abuts against the second positioning tooth 212.

[0063] Optionally, there may be multiple first positioning teeth 211 and one second positioning tooth 212. The second positioning tooth 212 may be engaged between two first positioning teeth 211 to restrict the rotation of the sound-generating part 1.

[0064] In some implementations, such as Figure 20 As shown, a first positioning tooth 211 is formed on a first anti-rotation body 21 and has a first limiting surface 2111. A second positioning tooth 212 is formed on a second anti-rotation body 131 and has a second limiting surface 2121. The first limiting surface 2111 is directed toward the rotation axis of the rotating pair (e.g., ...). Figure 8 , Figure 9 and Figure 20 The first limiting surface 2111 is tilted to one side (as indicated by mark I in the diagram), and the second limiting surface 2121 is tilted to the other side of the rotation axis of the rotating joint. The sound-generating part 1 rotates by a predetermined angle along the first rotation direction, and the first limiting surface 2111 pushes against the second limiting surface 2121 away from the first anti-rotation body 21. In this embodiment, the tilted first limiting surface 2111 and second limiting surface 2121 allow the wearer to more smoothly drive the sound-generating part 1 to rotate along the first rotation direction. Furthermore, by sliding the second positioning tooth 212 sequentially on multiple first positioning teeth 211, the wearer can indirectly perceive the approximate rotation amplitude of the sound-generating part 1.

[0065] In some implementations, such as Figures 8-11As shown, the sound-generating part 1 also includes a fixing bracket 15. The fixing bracket 15 is disposed inside the housing 11, and the fixing bracket 15 has a slide 151, a first receiving groove 152 and a second clearance hole 153, wherein the first receiving groove 152 communicates with the slide 151 and the second clearance hole 153.

[0066] The limiting member 13 includes a slider 133 and a guide block 134. A second anti-rotation body 131 is disposed on the slider 133, which is slidably disposed on the slide rail 151. A second connecting shaft 143 passes through the second clearance hole 153. The guide block 134 is located in the first receiving groove 152 and abuts against the second driving end 142. In this embodiment, the slide rail 151 is used to guide the movement of the limiting member 13, and the second pressing member 14 and the fixing bracket 15 can rotate together with the housing 11.

[0067] In some implementations, such as Figures 8-11 As shown, the second elastic body 121 is a compression spring, which is disposed in the first receiving groove 152 and abuts against the inner wall of the first receiving groove 152 and the side of the guide block 134 away from the second anti-rotation body 131. The second driving end 142 has a third guide surface 1421, which is inclined away from the second clearance hole 153 on the side near the first anti-rotation body 21. The guide block 134 has a fourth guide surface 132 that abuts against the third guide surface 1421. Further referencing... Figure 14 As shown, the compression spring pushes the second anti-rotation body 131 closer to the first anti-rotation body 21, and the limiting member 13 pushes the third guide surface 1421 against the first connecting hole 22 through the fourth guide surface 132. Thus, the third guide surface 1421 and the fourth guide surface 132 are always in contact, keeping the limiting member 13 and the second pressing member 14 moving synchronously.

[0068] In some implementations, such as Figure 5 As shown, the ear-hanging part 2 includes an intermediate body 23 and two connecting arms 24. A first anti-rotation body 21 and the two connecting arms 24 are disposed on the intermediate body 23, and the intermediate body 23 extends to both sides of the first anti-rotation body 21. One connecting arm 24 has a first connecting hole 22, and the other connecting arm 24 has a second connecting hole 241. Further referencing... Figures 8-10As shown, the housing 11 has a first mating hole 112 corresponding to the second connecting hole 241, and the fixing bracket 15 has a first clearance hole 154 corresponding to the second connecting hole 241. The sound-generating part 1 also includes a first connecting shaft 161. The first connecting shaft 161 passes through the second connecting hole 241, the first mating hole 112, and the first clearance hole 154, and the central axis of the first connecting shaft 161 is collinear with the central axis of the second connecting shaft 143. In this embodiment, the sound-generating part 1 is rotatably hung on the two connecting arms 24 through the second connecting shaft 143 and the first connecting shaft 161, respectively, which improves the stability of the connection between the sound-generating part 1 and the ear-mounted part 2. At the same time, the elastic force of the second elastic body 121 can act on the second connecting shaft 143 and the first connecting shaft 161 respectively, so that the elastic force is dispersed.

[0069] In some implementations, such as Figures 8-10 As shown, the mounting bracket 15 has a first clearance window 155. The first clearance window 155 communicates with the slide rail 151, and the housing 11 has a second clearance window 113 that at least partially corresponds to the first clearance window 155. Further referencing... Figure 10 and Figure 19 As shown, the first anti-rotation body 21 and the second anti-rotation body 131 abut against each other through the first clearance window 155 and the second clearance window 113. When the rotating joint rotates by a predetermined angle, the first anti-rotation body 21 abuts against the edge of the second clearance window 113. In this embodiment, the cooperation between the first clearance window 155 and the first anti-rotation body 21 limits the rotation range of the sound-generating part 1 and prevents the sound-generating part 1 from rotating excessively.

[0070] In some implementations, such as Figure 10 and Figure 11 As shown, the inner wall of the slide 151 has two slots 1511, which face opposite directions. The slider 133 has two protruding limiting hooks 1331, which are respectively configured to correspond to the two slots 1511. During the sliding of the slider 133 along the slide 151, the limiting hooks 1331 extend into the corresponding slots 1511 and move within them. In this embodiment, during the assembly of the sound-generating part 1, the cooperation between the limiting hooks 1331 and the slots 1511 can prevent the second elastic body 121 from pushing the limiting member 13 out of the slide 151, thus simplifying the assembly process of the sound-generating part 1.

[0071] In some implementations, such as Figure 8 and Figure 10As shown, the limiting member 13 also includes a connecting beam 135, which connects the slider 133 and the guide block 134. The second drive end 142 has a clearance surface 1422 that connects to the third guide surface 1421, and the clearance surface 1422 faces the connecting beam 135. This makes the second drive end 142 and the limiting member 13 more compact and provides space for the axial movement of the fixing frame 15 and the limiting member 13 along the mounting hole.

[0072] In some implementations, such as Figures 3-6 As shown, the ear-mounted part 2 also includes a fixing arm 25 and a transition member 26. The fixing arm 25 is along the first plane (e.g., Figure 14 and Figure 19 (As shown by the dashed line II in the diagram) the arm bends and extends to form a lug area 251, and the fixing arm 25 has a first connecting end 252. The transition member 26 includes two connecting arms 24, an intermediate body 23, and a first anti-rotation body 21. The intermediate body 23 has a second connecting end 231, and the first connecting end 252 and the second connecting end 231 have a first connected state and a second connected state. Further refer to... Figure 12 As shown, the sound-emitting part 1 includes a loudspeaker 17. In the first connection state, the diaphragm of the loudspeaker 17 faces one side of the first plane (e.g., Figure 1 (As shown). In the second connection state, the diaphragm of speaker 17 faces the other side of the first plane.

[0073] Specifically, one of the first connecting end 252 and the second connecting end 231 is a plug block, and the other is a plug slot. The plug block has two plugging directions (the two plugging directions are opposite) within the plug slot, so that the same sound-producing part 1 and ear hook part 2 can be assembled into headphones that are compatible with the left and right ears through two assembly methods. This further reduces material costs.

[0074] Optionally, the ear hook 2 may also include a battery and a flexible arm. The battery is located at the end of the flexible arm away from the sound-generating part 1. The battery is electrically connected to the speaker 17 via a cable disposed on the flexible arm.

[0075] In some implementations, such as Figures 8-9 As shown, one end of the second connecting shaft 143 is connected to the second pressing end 141, and its outer diameter is smaller than that of the second pressing end 141. The sound-generating part 1 also includes a retaining ring 19. The retaining ring 19 has a mounting notch 191, and the retaining ring 19 is disposed on the side of the second clearance hole 153 away from the second pressing end 141, and the second connecting shaft 143 passes through the retaining ring 19. The second elastic body 121 drives the limiting member 13 to push the second pressing end 141 against the second clearance hole 153 until the retaining ring 19 abuts between the end face of the second pressing end 141 and the edge of the second clearance hole 153.

[0076] In this embodiment, during the assembly of the sound-generating part 1, the limiting member 13 can be pressed in from the top of the slide 151 first, and the second elastic body 121 can be abutted between the guide block 134 and the inner wall of the first receiving groove 152. Then, the second driving end 142 is passed through the first connecting hole 22, the second mating hole 111 and the second clearance hole 153 in sequence and abutted against the guide block 134. In this form, the mounting notch 191 of the retaining ring 19 faces the second pressing member 14, and the retaining ring 19 is locked between the second driving end 142 and the inner wall of the first receiving groove 152, so as to simplify the assembly method of the sound-generating part 1.

[0077] Furthermore, such as Figures 5-8 As shown, both the second connecting shaft 143 and the first connecting shaft 161 include a large-diameter section and a small-diameter section. Further referencing... Figure 21 As shown, the large-diameter sections of the second connecting shaft 143 and the first connecting shaft 161 are used to connect with the lug 2 and the housing 11, and the small-diameter sections of the second connecting shaft 143 and the first connecting shaft 161 are used to connect with the fixing frame 15.

[0078] Figure 21 This is a schematic diagram of the unlocked state side of the locking member 3 in this embodiment. Figure 22 This is a schematic diagram of the locking state side of the locking member 3 in this embodiment. Figure 23 This is a schematic diagram of the other side of the unlocked state of the locking member 3 in this embodiment. Figure 24 This is a schematic diagram of the other side of the locking state of the locking member 3 in this embodiment.

[0079] In some implementations, such as Figures 7-9 and Figure 19 As shown, the sound-generating part 1 is disposed on the ear-hook part 2. The sound-generating part 1 includes a rotating member 18, a housing 11, a first elastic body 122, a fixing frame 15, and a locking member 3. The housing 11 has a mounting hole 116 and a first abutment surface 117. The locking member 3 includes an operating head 31 and a pad 32. The operating head 31 is movably disposed in the mounting hole 116. The rotating member 18 has a sound outlet 181 and a first anti-rotation area 182. The fixing frame 15 has a second abutment surface 159 and a second anti-rotation area 156. The rotating member 18 is rotatably connected to the housing 11, and the first elastic body 122 abuts between the operating head 31 and the fixing frame 15. Further referencing... Figure 20 , Figure 21 and Figure 23 As shown, the elastic force generated by the first elastic body 122 drives the second anti-rotation zone 156 to approach the first anti-rotation zone 182. The second anti-rotation zone 156 abuts against the first anti-rotation zone 182 and forms the first anti-rotation structure, and the pad 32 is spaced apart from the second abutment surface 159 (as shown). Figure 21(as shown by distance L1 in the diagram). Thus, in this embodiment, the first anti-rotation zone 182, the second anti-rotation zone 156, the locking member 3, and the housing 11 are in rigid contact, preventing the second anti-rotation zone 156 from moving toward the locking member 3.

[0080] Further reference Figure 22 and Figure 24 As shown, when the operating head 31 rotates to a predetermined angle ( Figure 24 As indicated by arrow a7), the pad 32 rotates to abut between the first abutment surface 117 and the second abutment surface 159, and abuts against both surfaces, while the second anti-rotation zone 156 abuts against the first anti-rotation zone 182. In this configuration, the wearer can drive the second anti-rotation zone 156 away from the first anti-rotation zone 182 using the first pressing member 16, or, when the friction between the first anti-rotation zone 182 and the second anti-rotation zone 156 is small, directly rotate the rotating member 18 to adjust the direction of the sound outlet 181.

[0081] In summary, the headphones of this embodiment rotatably connect the rotating member 18 to the shell member 11. When the wearer adjusts the wearing angle via the ear hook 2, the wearer can further adjust the orientation of the sound outlet 181 by rotating the rotating member 18, thus improving the wearer's listening experience. Therefore, on the one hand, by rotating the operating head 31, the wearer can abut the pad 32 between the first abutment surface 117 and the second abutment surface 159, keeping the first anti-rotation area 182 and the second anti-rotation area 156 in abutment. This effectively prevents the rotating member 18 from rotating when the wearer is wearing the headphones, ensuring that the sound outlet 181 faces a specific angle. On the other hand, the first elastic body 122 can drive the second anti-rotation zone 156 to abut against the first anti-rotation zone 182. In this form, the pad 32 is spaced apart from the second abutment surface 159. When the wearer rotates the rotating part 18, the first elastic body 122 can deform to move the second anti-rotation zone 156 away from the first anti-rotation zone 182, so as to avoid excessive friction between the second anti-rotation zone 156 and the first anti-rotation zone 182.

[0082] In some implementations, such as Figures 8-9 and Figures 23-24 As shown, there are multiple pads 32. The inner wall of the housing 11 has multiple pad blocks 41 corresponding to the multiple pads 32. The multiple pad blocks 41 are arranged around the mounting hole 116, and the side of the pad block 41 near the rotating member 18 forms a first abutment surface 117. The locking member 3 has a first position 51 and a second position 52 in the rotation direction. In the first position 51 (e.g....) Figure 23 As shown), each pad 32 is offset from its corresponding pad 41. At the second position 52 (as shown...) Figure 24 As shown, each pad 32 abuts against the corresponding pad block 41. In this embodiment, the pad block 41 can raise the height of the pad 32, so that the pad 32 is closer to the rotating member 18 and abuts against the fixing frame 15.

[0083] In some implementations, such as Figures 8-9 As shown, the fixing frame 15 includes an annular flange 61 and a body 62. The body 62 has a second anti-rotation zone 156, and the annular flange 61 protrudes from the body 62 and forms a second abutment surface 159 on its end face away from the body 62. Further referencing... Figure 19 As shown, the first elastic body 122 is located inside the annular flange 61 and abuts against the operating head 31 and the body 62. In this embodiment, the annular flange 61 is used to cooperate with the pad 32 for limiting the position, ensuring that the second abutment surface 159 can face the pad 32 after the pad 32 rotates. At the same time, it reduces the friction between the locking member 3 and the fixing frame 15.

[0084] In some implementations, such as Figures 8-9 and Figure 19 As shown, the body 62 has a protruding positioning post 621, and an annular flange 61 surrounds the positioning post 621. The operating head 31 has a receiving hole 311 facing the positioning post 621. The first elastic body 122 is a compression spring, one end of which is sleeved on the positioning post 621, and the other end extends into the receiving hole 311 and abuts against the bottom of the receiving hole 311.

[0085] Specifically, the inner diameter of the compression spring is larger than the outer diameter of the positioning post 621, so that when the locking member 3 drives the compression spring to rotate, the compression spring can rotate together. At the same time, the positioning post 621 and the receiving hole 311 can position the compression spring to prevent it from shifting between the fixing frame 15 and the locking member 3.

[0086] In some implementations, such as Figure 8 , Figure 23 and Figure 24 As shown, the inner wall of the housing 11 is provided with a plurality of stops 42. In the circumferential direction of the mounting hole 116, the stops 42 and pads 41 are alternately arranged, and the operating head 31 is operable to rotate in a preset direction. In the rotation direction, each stop 42 and the adjacent pad 41 form a receiving area 43. In the first position 51, the pad 32 is located in the corresponding receiving area 43. In this embodiment, the receiving area 43 is used to receive the pad 32 and, when the locking member 3 is away from the fixing frame 15, prevents the locking member 3 from rotating arbitrarily.

[0087] In some implementations, such as Figures 8-9 and Figures 23-24As shown, the stop 42 forms a first surface 421 on the side near the rotating member 18. The operating head 31 moves inward toward the housing 11 and rotates at a predetermined angle in a preset direction. The pad 32 abuts against the first contact surface 117, and in the axial direction of the mounting hole 116, the first surface 421 is closer to the rotating member 18 relative to the pad 32. In this embodiment, the height of the stop 42 is greater than the height of the pad 41. When the pad 32 abuts against the fixing frame 15, the locking member 3 can only rotate toward the pad 41. At the same time, when the locking member 3 rotates in the opposite direction, the stop 42 can also limit the pad 32, so that it falls accurately into the receiving area 43, thereby reducing the difficulty of operation for the wearer.

[0088] In some implementations, such as Figure 9 As shown, a limiting protrusion 322 protrudes from the side of the pad 32 away from the second abutment surface 159. The pad 32 has a first edge 321, which is located on the side of the pad 32 near the pad block 41, and a predetermined distance is maintained between the first edge 321 and the limiting protrusion 322 in the circumferential direction of the mounting hole 116. Further referencing... Figure 24 As shown, the pad 32 is in contact with the first abutting surface 117, and the side of the limiting protrusion 322 is at least partially opposite to the side of the pad 41. In this embodiment, when the pad 32 abuts with the first abutting surface 117, the side of the limiting protrusion 322 is at the same height as the pad 41. When the wearer excessively rotates the locking member 3 in a predetermined direction, the limiting protrusion 322 can abut with the side of the pad 41 to prevent the pad 32 from slipping to the side of the pad 41 away from the receiving area 43.

[0089] In some implementations, such as Figures 3-11 As shown, the sound-generating part 1 and the ear-hook part 2 form a rotating pair. The ear-hook part 2 includes a first anti-rotation body 21. The sound-generating part 1 also includes a second elastic body 121 and a limiting member 13. The second elastic body 121 and the limiting member 13 are disposed on the housing 11. The limiting member 13 includes a second anti-rotation body 131 and a moving block 136. The moving block 136 has a third position 53 and a fourth position 54 in the moving direction. The elastic force generated by the second elastic body 121 drives the second anti-rotation body 131 and the moving block 136 to approach the first anti-rotation body 21, and the second anti-rotation body 131 abuts against the first anti-rotation body 21 to form a second anti-rotation structure. At the same time, the moving block 136 moves from the third position 53 to the fourth position 54. The locking member 3 also includes a limiting plate 33. Further referencing... Figure 20 As shown, the operating head 31 rotates at a predetermined angle and is in the third position 53. The limiting plate 33 moves to the side of the moving block 136 near the first anti-rotation body 21 and abuts against the moving block 136. In this embodiment, the locking member 3 can also lock the limiting member 13, preventing the second anti-rotation body 131 from moving away from the first anti-rotation body 21 when the second anti-rotation body 131 abuts against the first anti-rotation body 21.

[0090] In some implementations, such as Figure 10 and Figure 11 As shown, the mounting bracket 15 has a slide rail 151, and the slide rail 151 has a window 1512, which is located on the side of the slide rail 151 near the locking member 3. The slider 133 is slidably disposed on the slide rail 151, and the moving block 136 extends from the window 1512. In this embodiment, the moving block 136 can abut against the edge of the window 1512 to limit the movement of the limiting member 13 in the extending direction of the slide rail 151.

[0091] In some implementations, such as Figures 19-24 As shown, when the locking member 3 is in the first position 51, the limiting plate 33 is misaligned with the moving block 136. Simultaneously, when the locking member 3 is in the second position 52, the limiting plate 33 abuts against the moving block 136 located in the third position 53. Therefore, when the wearer rotates the locking member 3 to a predetermined angle, both the first anti-rotation structure and the second anti-rotation structure can be locked simultaneously.

[0092] Furthermore, when the limiting protrusion 322 abuts against the pad 41, the limiting plate 33 is in a corresponding state with the moving block 136. This helps the wearer accurately judge the rotation angle of the locking member 3.

[0093] In some implementations, such as Figure 9 and Figure 23 As shown, the first plate edge 321 has a fifth guide surface 3211, which is inclined towards the rotating member 18 on the side near the pad 41. The pad 41 has a sixth guide surface 411. When the operating head 31 rotates by a predetermined angle, the fifth guide surface 3211 abuts against the sixth guide surface 411 and slides along the sixth guide surface 411. Thus, in this embodiment, the friction between the pad 32 and the pad 41 is reduced by the fifth guide surface 3211 and the sixth guide surface 411, allowing the wearer to rotate the operating head 31 more smoothly.

[0094] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can be modified and varied in various ways. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of protection of the present invention.
