Description

Technical Field

[0001] This invention relates to the field of headphone technology, and in particular to a type of over-ear headphone. Background Technology

[0002] Traditional headphones consist of a headband and speaker units mounted at both ends of the headband. To make headphones suitable for different users, the position of the speakers can be adjusted along the headband. The clamping force between the two speaker units of the headphones is mainly achieved through the relative position between the headband and the speakers.

[0003] However, while these traditional headphones can adapt to different head shapes, they cannot effectively adjust the clamping force over a wide range. In other words, the clamping force of traditional headphones is basically fixed, which can easily cause headaches for some users due to excessive tightness. Moreover, the clamping force tends to decrease over time, making it easy for them to become unwearable. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a headset with improved clamping force adjustment adaptability.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] A pair of headphones includes: a speaker device and a headband; the speaker device includes two opposing speaker wearing parts, each speaker wearing part including a correspondingly connected earcup and a speaker, each earcup being disposed adjacent to the sound outlet of the corresponding speaker, and the opening directions of the sound outlets of the two speakers being arranged facing each other; the headband includes a flexible headband shell and a headband clamping assembly, the flexible headband shell being respectively connected to the two speakers, the headband clamping assembly being located inside the flexible headband shell, the headband clamping assembly including a clamping bow arm member, a clamping bow string member, and an adjusting member, the clamping bow arm member having a bow groove, the opening of the bow groove facing the speaker device, at least a portion of the clamping bow string member being located within the bow groove, the clamping bow string member movably abutting against the bow groove, the flexible headband shell having a mounting hole, the adjusting member being movably disposed within the mounting hole, the adjusting member being connected to the clamping bow string member to move the clamping bow string member away from or closer to the mounting hole.

[0007] In one embodiment, the mounting hole is located on the side of the flexible head-mounted housing near the speaker device, and the adjusting member is movably disposed within the mounting hole and the flexible head-mounted housing. The end of the adjusting member away from the speaker device abuts against the clamping bowstring member to push the clamping bowstring member away from or towards the mounting hole.

[0008] In one embodiment, the clamping bow arm has a first through hole corresponding to the mounting hole, and the adjusting member passes through the mounting hole and the first through hole in sequence. The portion of the adjusting member located on the flexible head-mounted shell is movably connected to the clamping bow string member so that the clamping bow string member is away from or close to the first through hole. The mounting hole is located on the side of the flexible head-mounted shell opposite to the speaker device.

[0009] In one embodiment, the adjusting member is movably engaged within at least one of the first through hole and the mounting hole, so that the adjusting member is movably engaged with at least one of the flexible headgear shell and the clamping bow arm.

[0010] In one embodiment, the adjusting member includes an adjusting rod and a plurality of adjusting protrusions, the plurality of adjusting protrusions being disposed on the surface of the adjusting rod, and at least one adjusting protrusion abutting against at least one inner wall of the first through hole and the mounting hole to adjust the length of the adjusting rod extending into the flexible headgear shell.

[0011] In one embodiment, the bowstring clamping member has a second through hole, the adjusting member is movably engaged in the mounting hole, and the adjusting member also passes through the second through hole and is screwed to the bowstring clamping member.

[0012] In one embodiment, the adjusting member has a threaded adjusting groove communicating with the mounting hole. The opening of the threaded adjusting groove is disposed away from the clamping bowstring member. The threaded adjusting groove is used to accommodate a threaded rotator to rotate the adjusting member.

[0013] In one embodiment, the bowstring clamping member includes a bowstring body and a first guide plate connected to each other. The bowstring body slides against the side of the bow arm clamping member near the speaker device. The first guide plate slides against the side of the bow arm clamping member. The bowstring body and the first guide plate form a guide groove. A portion of the bow arm clamping member slides through the guide groove.

[0014] In one embodiment, the bowstring clamping member includes a second guide plate connected to the first guide plate, the second guide plate slidingly abutting against the side of the bow arm clamping member opposite to the speaker device.

[0015] In one embodiment, the flexible head-mounted shell has heat dissipation holes that communicate with the interior of the flexible head-mounted shell and are used to dissipate heat from the flexible head-mounted shell.

[0016] Compared with the prior art, the present invention has at least the following advantages:

[0017] When the clamping force needs to be adjusted, the adjusting component connected to the clamping bowstring is adjusted to move the clamping bowstring away from or closer to the mounting hole, so that the clamping bowstring slides on the clamping bow arm, thereby causing the two ends of the clamping bow arm to fold or unfold. This, in turn, causes the clamping bow arm to move the flexible headband shell in and out, making it easier to adjust the clamping force generated by the headphones and effectively improving the adaptability of the clamping force adjustment.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] This invention relates to a pair of headphones. In one embodiment, the headphones include a speaker device and a headband. The speaker device includes two opposing speaker fittings. Each speaker fitting includes a correspondingly connected earcup and a speaker. Each earcup is disposed adjacent to the sound outlet of the corresponding speaker, and the openings of the two speaker outlets are oriented towards each other. The headband includes a flexible headband shell and a headband clamping assembly. The flexible headband shell is connected to the two speakers respectively. The headband clamping assembly is located within the flexible headband shell and includes a bow arm clamping member, a bow string clamping member, and an adjustment member. The bow arm clamping member has a bow groove, the opening of which faces the speaker device. At least a portion of the bow string clamping member is located within the bow groove, and the bow string clamping member movably abuts against the bow groove. The flexible headband shell has a mounting hole, and the adjusting member is movably inserted into the mounting hole. The adjusting member is connected to the clamping bowstring member, allowing the clamping bowstring member to move away from or closer to the mounting hole. When the clamping force needs to be adjusted, the adjusting member connected to the clamping bowstring member is adjusted to move the clamping bowstring member away from or closer to the mounting hole, causing the clamping bowstring member to slide on the clamping bow arm member. This causes the two ends of the clamping bow arm member to retract or expand, which in turn causes the clamping bow arm member to drive the flexible headband shell to retract or expand. This facilitates the adjustment of the clamping force generated by the headphones and effectively improves the adaptability of the clamping force adjustment.

[0029] Please see Figure 1 This is a schematic diagram of the structure of a headset according to an embodiment of the present invention.

[0030] One embodiment of the headphones 10 includes a speaker device 100 and a headband 200. The speaker device 100 includes two opposing speaker wearing parts 110. Each speaker wearing part 110 includes a correspondingly connected earcup 112 and a speaker 114. Each earcup 112 is disposed adjacent to the sound outlet of the corresponding speaker 114, and the opening directions of the sound outlets of the two speakers 114 are facing each other. Please refer to the accompanying document. Figure 2 The head-mounted device 200 includes a flexible head-mounted shell 210 and a head-mounted clamping assembly 220. The flexible head-mounted shell 210 is connected to two of the speakers 114. The head-mounted clamping assembly 220 is located within the flexible head-mounted shell 210 and includes a bow arm clamping member 222, a bow string clamping member 224, and an adjusting member 226. The bow arm clamping member 222 has a bow groove 222a, the opening of which faces the speaker device 100. At least a portion of the bow string clamping member 224 is located within the bow groove 222a, and the bow string clamping member 224 movably abuts against the bow groove 222a. The flexible headgear shell 210 has a mounting hole 212, and the adjusting member 226 is movably inserted into the mounting hole 212. The adjusting member 226 is connected to the clamping bowstring member 224 so that the clamping bowstring member 224 is away from or close to the mounting hole 212.

[0031] In this embodiment, when the clamping force needs to be adjusted, the adjusting member 226 connected to the clamping bowstring member 224 is adjusted to move the clamping bowstring member 224 away from or closer to the mounting hole 212, so that the clamping bowstring member 224 slides on the clamping bow arm member 222, thereby causing the two ends of the clamping bow arm member 222 to close or expand, and then the clamping bow arm member 222 drives the flexible headband shell 210 to open and close, which facilitates the adjustment of the clamping force generated by the headphone and effectively improves the adaptability of the clamping force adjustment.

[0032] In one embodiment, the mounting hole is located on the side of the flexible head-mounted shell near the speaker device. The adjusting member is movably disposed within the mounting hole and the flexible head-mounted shell. The end of the adjusting member away from the speaker device abuts against the clamping bowstring member to push the clamping bowstring member away from or towards the mounting hole. In this embodiment, the mounting hole is positioned opposite to a portion of the clamping bow arm member. Specifically, the mounting hole is positioned opposite to the middle portion of the clamping bow arm member, that is, the mounting hole and the middle portion of the clamping bow arm member are symmetrical about the clamping bowstring member as a centerline, and the opening direction of the mounting hole is the same as the opening direction of the bow groove. The mounting hole is used to accommodate a portion of the adjusting member. The adjusting member is movable within the mounting hole, and the adjusting member pushes the clamping bowstring member, facilitating the unfolding or retraction of the clamping bow arm member during movement, thereby facilitating the unfolding and retraction of the clamping bow arm member. In another embodiment, the adjusting member is fully housed within the mounting hole and the flexible headgear shell, the adjusting member rotates within the mounting hole, and the adjusting member is screwed to the clamping bowstring member, facilitating the pushing of the clamping bowstring member when the adjusting member rotates.

[0033] In one embodiment, please refer to Figures 3 to 5The clamping bow arm component 222 has a first through hole 222b corresponding to the mounting hole 212. The adjusting component 226 passes through the mounting hole 212 and the first through hole 222b in sequence. The portion of the adjusting component 226 located on the flexible head-mounted shell 210 is movably connected to the clamping bow string component 224 so that the clamping bow string component 224 is away from or close to the first through hole 222b. The mounting hole 212 is located on the side of the flexible head-mounted shell 210 facing away from the speaker device 100. In this embodiment, the mounting hole 212 is located on the side of the flexible head-mounted shell 210 facing away from the speaker device 100. The mounting hole 212 is positioned opposite to the bowstring clamping member 224. Specifically, the mounting hole 212 is positioned opposite to the middle of the bowstring clamping member 224, meaning that the mounting hole 212 and the middle of the bowstring clamping member 224 are symmetrical about the bow arm clamping member 222. In other words, the opening direction of the mounting hole 212 is opposite to the opening direction of the bow groove 222a. The adjusting member 226 passes through the mounting hole 212. Since the mounting hole 212 is located on the flexible head-mounted shell 210 facing away from the user's head, the probability of a sharp, protruding sensation from the adjusting member 226 is reduced, i.e., the probability of the adjusting member 226 protruding from the flexible head-mounted shell 210 is reduced. The first through hole 222b corresponds to the mounting hole 212. Specifically, the first through hole 222b and the mounting hole 212 are aligned to facilitate the adjustment member 226 passing through the flexible headgear shell 210 and the clamping bow arm member 222 in sequence. Thus, after the adjustment member 226 passes through the first through hole 222b, one end of the adjustment member 226 located inside the flexible headgear shell 210 is connected to the clamping bowstring member 224. When the adjustment member 226 extends, retracts, or rotates within the mounting hole 212 and the first through hole 222b, the adjustment member 226 will drive the clamping bowstring member 224 to move, causing the clamping bowstring member 224 to move within the bow groove 222a. This allows the clamping bowstring member 224 to slide on the surface of the clamping bow arm member 222, facilitating the unfolding or retraction of the clamping bow arm member 222.

[0034] Furthermore, the adjusting member 226 is movably engaged within at least one of the first through hole 222b and the mounting hole 212, so that the adjusting member 226 is movably engaged with at least one of the headband flexible shell 210 and the clamping bow arm member 222. In this embodiment, the adjusting member 226 is movably disposed within at least one of the first through hole 222b and the mounting hole 212, such that the adjusting member 226 contacts at least one of the flexible headgear shell 210 and the clamping bow arm member 222. When the adjusting member 226 pushes the clamping bowstring member 224, the adjusting member 226, depending on its engagement with at least one of the flexible headgear shell 210 and the clamping bow arm member 222, can easily lock itself after adjusting the position of the clamping bowstring member 224, thereby improving the connection stability between the clamping bowstring member 224 and the clamping bow arm member 222, and ensuring the stability of the extension and retraction of the clamping bow arm member 222, that is, the clamping force remains stable after extension and retraction.

[0035] Furthermore, please refer to Figure 5 The adjusting member 226 includes an adjusting rod 2262 and a plurality of adjusting protrusions 2264. The plurality of adjusting protrusions 2264 are disposed on the surface of the adjusting rod 2262. At least one adjusting protrusion 2264 abuts against at least one inner wall of the first through hole 222b and the mounting hole 212 to adjust the length of the adjusting rod 2262 extending into the flexible headgear shell 210. In this embodiment, the adjusting rod 2262 passes through both the first through hole 222b and the mounting hole 212. The adjusting rod 2262 serves as the main body of the adjusting member 226 and is used to adjust the position of the plurality of adjusting protrusions 2264 thereon. The first through hole 222b and the mounting hole 212 are respectively provided with the adjustment protrusion 2264. The setting of the adjustment protrusion 2264 increases the surface roughness of the adjustment member 226, thereby increasing the friction between the adjustment member 226 and the inner wall of the first through hole 222b and the inner wall of the mounting hole 212. As a result, after the position of the clamping bowstring member 224 is adjusted, the adjustment member 226 can still be stably opened on the headband flexible shell 210 and the clamping bow arm member 222, further improving the connection stability between the clamping bowstring member 224 and the clamping bow arm member 222.

[0036] Furthermore, please refer to Figure 5The bowstring clamping member 224 has a second through hole 224a. The adjusting member 226 is movably engaged in the mounting hole 212. The adjusting member 226 also passes through the second through hole 224a and is screwed to the bowstring clamping member 224. In this embodiment, the second through hole 224a corresponds to both the mounting hole 212 and the first through hole 222b. When the adjusting member 226 is installed on the flexible headgear shell 210, the adjusting member 226 passes through the mounting hole 212, the first through hole 222b, and the second through hole 224a in sequence until the adjusting member 226 is screwed to the bowstring clamping member 224. The inner wall of the second through hole 224a has a thread that matches the surface of the adjusting member 226. That is, the inner wall thread of the second through hole 224a and the surface thread of the adjusting member 226 are engaged with each other, which facilitates the rotation of the adjusting member 226 in the second through hole 224a. This allows the adjusting member 226 to push the clamping bowstring member 224 to move by rotation, thereby enabling the clamping bowstring member 224 to move on the clamping bow arm member 222, which facilitates the opening and closing operation of the clamping bow arm member 222.

[0037] Furthermore, please refer to Figure 3 The adjusting member 226 has a threaded adjusting groove 226a communicating with the mounting hole 212. The opening of the threaded adjusting groove 226a is positioned away from the clamping bowstring member 224. The threaded adjusting groove 226a is used to accommodate a threaded rotator to rotate the adjusting member 226. In this embodiment, the opening of the threaded adjusting groove 226a faces outward from the bow groove 222a, that is, the opening direction of the threaded adjusting groove 226a is opposite to the opening direction of the bow groove 222a. When it is necessary to rotate the adjusting member, that is, to adjust the extension and retraction of the clamping bow arm 222, the rotating blade of the screw rotator is embedded in the screw adjustment groove 226a, which facilitates the rotation of the adjusting member. This allows the adjusting member to move the clamping bow string 224 while it is screwed to the clamping bow string 224, thereby facilitating the adjustment of the clamping force of the clamping bow arm 222, and thus facilitating the adjustment of the clamping force of the headphones.

[0038] In one embodiment, please refer to Figure 3The bowstring clamping component 224 includes a bowstring body 2242 and a first guide plate 2244 connected to each other. The bowstring body 2242 slidably abuts against the side of the bow arm clamping component 222 near the speaker device 100. The first guide plate 2244 slidably abuts against the side of the bow arm clamping component 222. The bowstring body 2242 and the first guide plate 2244 form a guide groove 224b, and a portion of the bow arm clamping component 222 slidably passes through the guide groove 224b. In this embodiment, the bowstring body 2242 is located within the bow bending groove 222a, and the end of the bowstring body 2242 abuts against the inner wall of the bow bending groove 222a, so that the end of the bowstring body 2242 contacts the inner surface of the bow arm clamping component 222. The first guide plate 2244 extends relative to the bowstring body 2242 to the side of the clamping bow arm 222, such that the first guide plate 2244 abuts against the side of the clamping bow arm 222, thereby ensuring that the first guide plate 2244 is tightly attached to the side of the clamping bow arm 222, providing guidance for the bowstring body 2242 to slide on the clamping bow arm 222. The guide groove 224b is a groove formed by the bowstring body 2242 and the first guide plate 2244. One sidewall of the guide groove 224b slides against the clamping bow arm 222, and the side of the guide groove 224b adjacent to it abuts against the side of the clamping bow arm 222, facilitating the placement of the clamping bow arm 222 within the guide groove 224b, thereby facilitating the stable sliding of the clamping bowstring 224 on the clamping bow arm 222.

[0039] Further, please refer to Figure 3The bowstring clamping member 224 further includes a second guide plate 2246 connected to the first guide plate 2244, and the second guide plate 2246 slides against the side of the bow arm clamping member 222 that is away from the speaker device 100. In this embodiment, the second guide plate 2246 is disposed opposite to the bowstring body 2242. The bowstring body 2242 is connected to the second guide plate 2246 via the first guide plate 2244. That is, the second guide plate 2246 and the bowstring body 2242 are symmetrically disposed with the clamping bow arm member 222 as the center line, so that the first guide plate 2244 and the second guide plate 2246 respectively abut against the two side walls of the clamping bow arm member 222. That is, the first guide plate 2244 slides against the inner side wall of the clamping bow arm member 222, and the second guide plate 2246 slides against the outer side wall of the clamping bow arm member 222. The first guide plate 2244 and the second guide plate 2246 restrict the clamping bow arm member 222 within the guide groove 224b, thereby better guiding the extension and retraction direction of the clamping bow arm member 222. In another embodiment, there are two first guide plates, and the two first guide plates, one second guide plate, and the bowstring body form a guide hole to facilitate the complete confinement and guidance of the clamping bow arm.

[0040] In one embodiment, the flexible headband shell has heat dissipation holes that communicate with the interior of the flexible headband shell. These holes are used to dissipate heat from within the flexible headband shell. In this embodiment, since the headphones have two opposing speakers, corresponding circuit boards or lines are required for simultaneous control of the two speakers, which causes the flexible headband shell to generate heat. The heat dissipation holes, acting as through-holes connecting the flexible headband shell to the outside, dissipate heat generated by the operation of electronic components within the flexible headband shell, reducing the likelihood of damage due to overheating.

[0041] Understandably, when the bowstring clamping member 224 slides on the bow arm clamping member 222, the bowstring clamping member 224 expands and contracts the bow arm clamping member 222 through the first guide plate 2244, the second guide plate 2246, and the bowstring body 2242. That is, the guide groove 224b on the bowstring clamping member 224 and the second guide plate 2246 jointly expand and contract the bow arm clamping member 222, thereby adjusting the clamping force of the bow arm clamping member 222 and making it easy to change the clamping force of the headphones according to actual needs.

[0042] However, during the retraction and extension process, the change in the abutment between the clamping bow arm 222 and the inner wall of the flexible headband shell 210 takes time. For example, when the headphones need to be clamped, the clamping bow arm 222 initially contacts the first inner wall of the flexible headband shell 210. Then, under the push of the clamping bow string 224, the clamping bow arm 222 contacts the second inner wall of the flexible headband shell 210, with the first and second inner walls of the flexible headband shell 210 positioned opposite each other. During this process, the change in the clamping force of the clamping bow arm 222 takes a certain amount of time and cannot achieve clamping quickly, i.e., the clamping force cannot be increased quickly. Moreover, this phenomenon is particularly obvious at the end of the clamping bow arm 222; that is, the further away from the clamping bow string 224 the clamping bow arm 222 is from the clamping bow string 224, the slower the change in clamping force.

[0043] To increase the rate of increase in clamping force, please refer to [link / reference]. Figure 3 The bow arm clamping component 222 further includes a first bow arm clamping spring piece 2222 and a second bow arm clamping spring piece 2224 stacked together. The bending radius of the first bow arm clamping spring piece 2222 is smaller than the bending radius of the second bow arm clamping spring piece 2224. Both the first bow arm clamping spring piece 2222 and the second bow arm clamping spring piece 2224 are inserted into the guide groove 224b. The side of the first bow arm clamping spring piece 2222 facing away from the second bow arm clamping spring piece 2224 slides against the bowstring body 2242. The side of the second bow arm clamping spring piece 2224 facing away from the first bow arm clamping spring piece 2222 slides against the second guide plate 2246.

[0044] In this embodiment, the first clamping bow arm spring 2222 and the second clamping bow arm spring 2224 are stacked. For example, the first clamping bow arm spring 2222 is positioned close to the speaker device 100, and the second clamping bow arm spring 2224 is located on the side of the first clamping bow arm spring 2222 that faces away from the speaker device 100, i.e., the second clamping bow arm spring 2224 is stacked on top of the first clamping bow arm spring 2222. Both the first clamping bow arm spring 2222 and the second clamping bow arm spring 2224 are curved structures to match the structure of the flexible headgear shell 210, i.e., to match the shape of the human head, so that the bending direction of the first clamping bow arm spring 2222 and the second clamping bow arm spring 2224 is towards the human head, which facilitates applying sufficient clamping force to the flexible headgear shell 210. The bending radius of the first clamping bow arm spring 2222 is different from that of the second clamping bow arm spring 2224. Specifically, the bending radius of the first clamping bow arm spring 2222 is set to be smaller than that of the second clamping bow arm spring 2224, so that the distance between the first clamping bow arm spring 2222 and the second clamping bow arm spring 2224 gradually increases from the middle to the end, thereby making the first clamping bow arm spring 2222 more inward than the second clamping bow arm spring 2224, that is, the end of the first clamping bow arm spring 2222 is closer to the human head. In this design, the distance between the first clamping bow arm spring piece 2222 and the second clamping bow arm spring piece 2224 gradually increases from the middle to the end. When the clamping bow string member 224 retracts the clamping bow arm member 222, the increase in clamping force is attenuated, that is, the increase in clamping force in the retracted state gradually decreases, which facilitates fine adjustment of the final required clamping force and effectively reduces excessive compression on the human head during the adjustment of clamping force.

[0045] Thus, when both the first clamping bow arm spring 2222 and the second clamping bow arm spring 2224 are inserted into the guide groove 224b, the contact point between the first clamping bow arm spring 2222 and the bowstring body 2242 is the support point, and the contact point between the second clamping bow arm spring 2224 and the second guide plate 2246 is the retraction point. As the middle part of the clamping bowstring member 224 gradually moves away from the mounting hole 212, that is, the clamping bow arm member 222 gradually retracts, initially, the second clamping bow arm spring 2224 contacts the outer shell of the headband flexible shell 210, and the second guide plate 2246 presses the second clamping bow arm spring 2224, causing the second clamping bow arm spring 2224 to move toward the first clamping bow arm spring 2222. Within the guide groove 224b, the contact point between the first clamping bow arm spring 2222 and the bowstring body 2242 serves as a support point. This facilitates the rapid transmission of the bending deformation of the second clamping bow arm spring 2224 to the first clamping bow arm spring 2222 through this support point. This allows the first clamping bow arm spring 2222 to respond quickly to the deformation of the second clamping bow arm spring 2224, thereby increasing the deformation response rate of the first clamping bow arm spring 2222. This effectively enhances the compression of the first clamping bow arm spring 2222 onto the headband flexible shell 210, thus facilitating the rapid transmission of the clamping force generated by the deformation of the second clamping bow arm spring 2224 to the first clamping bow arm spring 2222. Consequently, this rapidly increases the clamping force of the headphone.

[0046] In another embodiment, please refer to Figure 3 The clamping bow arm component 222 further includes a third clamping bow arm spring piece 2226. The third clamping bow arm spring piece 2226 is located between the first clamping bow arm spring piece 2222 and the second clamping bow arm spring piece 2224. The bending radius of the third clamping bow arm spring piece 2226 is greater than that of the first clamping bow arm spring piece 2222, and smaller than that of the second clamping bow arm spring piece 2224. The third clamping bow arm spring piece 2226 serves as an auxiliary spring piece, filling the gap between the first clamping bow arm spring piece 2222 and the second clamping bow arm spring piece 2224 within the bow groove 222a. This facilitates the rapid transfer of the clamping force generated by the deformation of the first clamping bow arm spring piece 2222 to the second clamping bow arm spring piece 2224, further improving the response speed of the clamping force of the headphones.

[0047] Furthermore, when the second clamping bow arm spring 2224 presses against the first clamping bow arm spring 2222 by the third clamping bow arm spring 2226, there is a possibility that the adjusting member 226 rotates too quickly. This can easily cause the clamping bow arm 222 to retract too quickly, thereby causing the earmuff 112 to snap onto the user's ear, creating an explosive sound and damaging the eardrum. To reduce the likelihood of the clamping bow arm 222 retracting too quickly, please refer to... Figure 6 The headgear 200 further includes a resistance amplifier 230, which includes a first connecting rod 232, a second connecting rod 234, a third connecting rod 236, a first resistance amplifying spring 238, a second resistance amplifying spring 231, a first rotating shaft 233, and a second rotating shaft 235. The first resistance amplifying spring 238 is connected to the first connecting rod 232 and the third connecting rod 236, and is sleeved on the first rotating shaft 233. The first connecting rod 232 is connected to the first clamping bow arm spring 2222. The second resistance amplifying spring 231 is connected to the second connecting rod 234 and the third connecting rod 236, and is sleeved on the second rotating shaft 235. The second connecting rod 234 is connected to the second clamping bow arm spring 2224. The first rotating shaft 233 and the second rotating shaft 235 are both connected to the third clamping bow arm spring 2226. In this embodiment, the first resistance-increasing spring 238 is connected to the third clamping bow arm spring 2226 via the first rotating shaft 233, and the second resistance-increasing spring 231 is connected to the third clamping bow arm spring 2226 via the second rotating shaft 235. This allows the first connecting rod 232 to rotate around the first rotating shaft 233, and the second connecting rod 234 to rotate around the second rotating shaft 235. Consequently, the first resistance-increasing spring 238 provides elastic resistance to the first connecting rod 232, and the second resistance-increasing spring 231 provides elastic resistance to the second connecting rod 234. This results in a portion of the deformation force transmitted from the second clamping bow arm spring 2224 to the third clamping bow arm spring 2226 via the first clamping bow arm spring 2222 being distributed between the first resistance-increasing spring 238 and the second resistance-increasing spring 231. This facilitates slowing down the retraction rate of the clamping bow arm 222, effectively reducing the likelihood of the headphones retracting too quickly and ensuring normal use by the user. The third clamping bow arm spring has a third through hole, and the third connecting rod passes through the third through hole, so that the first connecting rod and the second connecting rod are located on both sides of the third clamping bow arm spring, that is, the first connecting rod abuts against the first clamping bow arm spring, and the second connecting rod abuts against the second clamping bow arm spring.
