In this embodiment, the mounting hole 212 is opened on a surface of the flexible head mount housing 210 facing away from the speaker device 100, the mounting hole 212 is located opposite to the clip bow-string member 224, specifically, the mounting hole 212 is located opposite to a middle portion of the clip bow-string member 224, that is, the mounting hole 212 and the middle portion of the clip bow-string member 224 are symmetrical about the clip bow-string member 222 as a center line, that is, an opening direction of the mounting hole 212 is opposite to an opening direction of the bow groove 222 a. The adjusting piece 226 penetrates through the mounting hole 212, and the mounting hole 212 is located at a position where the flexible head-mounted shell 210 deviates from the head of the user, so that the probability of sharp and sharp prick caused by the adjusting piece 226, namely the probability of the adjusting piece 226 protruding out of the flexible head-mounted shell 210, is reduced. The first through hole 222b corresponds to the mounting hole 212, and in particular, the first through hole 222b is aligned with the mounting hole 212, so that the adjusting member 226 can pass through the flexible headset housing 210 and the clamping bow member 222 in sequence. Thus, after the adjusting member 226 passes through the first through hole 222b, the end of the adjusting member 226 located in the flexible head-mounted housing 210 is connected to the clamping bow-string member 224, and when the adjusting member 226 is extended or rotated in the mounting hole 212 and the first through hole 222b, the adjusting member 226 will move the clamping bow-string member 224, so that the clamping bow-string member 224 moves in the bow groove 222a, and the clamping bow-string member 224 slides on the surface of the clamping bow-string member 222, thereby facilitating the expansion or contraction of the clamping bow-string member 222.

Further, the adjusting member 226 is movably engaged with 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 flexible head-mounted shell 210 and the clamping bow member 222. In this embodiment, the adjusting member 226 is movably disposed in at least one of the first through hole 222b and the mounting hole 212, such that the adjusting member 226 contacts with at least one of the flexible head casing 210 and the clamping bow arm member 222, when the adjusting member 226 pushes the clamping bow string member 224, the adjusting member 226 is convenient to be clamped after the position of the clamping bow string member 224 is adjusted according to the clamping condition with at least one of the flexible head casing 210 and the clamping bow arm member 222, and the connection stability between the clamping bow string member 224 and the clamping bow arm member 222 is improved, thereby ensuring the folding stability of the clamping bow arm member 222, i.e. the clamping force is kept stable after folding.

Further, referring to fig. 5, the adjusting member 226 includes an adjusting lever 2262 and a plurality of positioning rings 2264, the positioning rings 2264 are disposed on a surface of the adjusting lever 2262, and at least one positioning ring 2264 abuts against at least one inner wall of the first through hole 222b and the mounting hole 212 to adjust a length of the adjusting lever 2262 extending into the flexible head-mounted housing 210. In this embodiment, the adjusting rod 2262 is simultaneously inserted into the first through hole 222b and the mounting hole 212, and the adjusting rod 2262 serves as a main body of the adjusting member 226 for adjusting the positions of the positioning rings 2264 thereon. The positioning collars 2264 are correspondingly disposed in the first through hole 222b and the mounting hole 212, and the positioning collars 2264 increase the surface roughness of the adjusting part 226, so that the friction between the adjusting part 226 and the inner walls of the first through hole 222b and the mounting hole 212 is increased, and the adjusting part 226 can be stably disposed on the flexible headgear shell 210 and the clamping bow arm piece 222 after the position of the clamping bow string piece 224 is adjusted, thereby further improving the connection stability between the clamping bow string piece 224 and the clamping bow arm piece 222.

Still further, referring to fig. 5, the clamping bow string member 224 is provided with a second through hole 224a, the adjusting member 226 is movably clamped in the mounting hole 212, and the adjusting member 226 is further inserted into the second through hole 224a and is screwed with the clamping bow string member 224. In this embodiment, the second through hole 224a corresponds to the mounting hole 212 and the first through hole 222b, and when the adjusting member 226 is mounted 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 with the clip bow string member 224. Wherein the inner wall of the second through hole 224a has a thread matching 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, so as to facilitate the rotation of the adjusting member 226 in the second through hole 224a, thereby the adjusting member 226 rotationally pushes the clamping bow string member 224 to move, and further the clamping bow string member 224 moves on the clamping bow arm member 222, and the clamping bow arm member 222 performs the retracting operation.

Still further, referring to fig. 3, the adjusting member 226 is provided with a screw thread adjusting groove 226a communicating with the mounting hole 212, an opening of the screw thread adjusting groove 226a is disposed away from the clamping bow string member 224, and the screw thread adjusting groove 226a is used for receiving a screw thread rotator to rotate the adjusting member 226. In the present embodiment, the opening of the screw thread adjusting groove 226a faces the outside of the bow groove 222a, i.e., the opening direction of the screw thread adjusting groove 226a is opposite to the opening direction of the bow groove 222 a. When the adjusting member needs to be rotated, i.e., the expansion and contraction of the clamping bow arm member 222 are adjusted, a portion of the rotating bit of the screw-on rotator is embedded in the screw-on adjusting groove 226a, so that the adjusting member is rotated, and the adjusting member moves the clamping bow member 224 under the condition of being screwed with the clamping bow member 224, thereby facilitating the adjustment of the clamping force of the clamping bow arm member 222, and further facilitating the adjustment of the clamping example of the headset.

In one embodiment, referring to fig. 3, the clip bow member 224 includes a bow body 2242 and a first guide plate 2244, which are connected to each other, the bow body 2242 slidably abuts against a surface of the clip bow member 222 close to the speaker 100, the first guide plate 2244 slidably abuts against a side edge of the clip bow member 222, the bow body 2242 and the first guide plate 2244 form a guide slot 224b, and a portion of the clip bow member 222 slidably penetrates through the guide slot 224 b. In this embodiment, the bowstring body 2242 is located in the bow groove 222a, and the end of the bowstring body 2242 abuts against the inner wall of the bow groove 222a, so that the end of the bowstring body 2242 contacts the inner surface of the clamping bow arm 222. The first guide plate 2244 extends to the side of the clamping bow arm piece 222 relative to the bow-string body 2242, so that the first guide plate 2244 abuts against the side of the clamping bow arm piece 222, so that the first guide plate 2244 is tightly attached to the side of the clamping bow arm piece 222, and a guiding function is provided for the sliding of the bow-string body 2242 on the clamping bow arm piece 222. The guide groove 224b is a groove formed by the bowstring body 2242 and the first guide plate 2244, one side wall of the guide groove 224b is in sliding contact with the clamping bow arm piece 222, and the side adjacent to the guide groove 224b is in contact with the side edge of the clamping bow arm piece 222, so that the guide groove 224b can conveniently hold the clamping bow arm piece 222 therein, and the clamping bow piece 224 can stably slide on the clamping bow arm piece 222.

Further, referring to fig. 3, the clip bow member 224 further includes a second guide plate 2246 connected to the first guide plate 2244, and the second guide plate 2246 is in sliding contact with a surface of the clip bow member 222 facing away from the speaker device 100. In this embodiment, the second guide plate 2246 and the bowstring body 2242 are disposed opposite to each other, and the bowstring body 2242 is connected to the second guide plate 2246 through 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 222 as a center line, so that the first guide plate 2244 and the second guide plate 2246 are respectively abutted against both side walls of the clamping bow arm 222, that is, the first guide plate 2244 is slidably abutted against the inner side wall of the clamping bow arm 222, the second guide plate 2246 is slidably abutted against the outer side wall of the clamping bow arm 222, and the first guide plate 2244 and the second guide plate 2246 restrict the clamping bow arm 222 in the guide groove 224b, preferably, guide the extending and retracting direction of the clamping bow arm 222. In another embodiment, the number of the first guide plates is two, and two of the first guide plates, one of the second guide plates, and the bowstring body form guide holes for completely confining and guiding the clamping bow arm members therein.

In one embodiment, the head-wearing flexible shell is provided with heat dissipation holes, the heat dissipation holes are communicated with the interior of the head-wearing flexible shell, and the heat dissipation holes are used for conducting heat out of the interior of the head-wearing flexible shell. In this embodiment, since the headset has two speakers disposed opposite to each other, the two speakers need to be connected through a corresponding circuit board or circuit, which facilitates simultaneous control of the two speakers, and thus the flexible headset housing generates heat. The louvre is as wear the through-hole of flexible shell and outside intercommunication, the louvre spare wear in the flexible shell because of the heat that electron device work produced leads to, reduced wear the inside probability of damaging because of overheated of flexible shell.

As can be understood, when the clamping bow-string component 224 slides on the clamping bow-string component 222, the clamping bow-string component 224 expands the clamping bow-string component 222 through the first guide plate 2244, the second guide plate 2246 and the bow-string body 2242, that is, the guide slot 224b on the clamping bow-string component 224 and the second guide plate 2246 jointly expand the clamping bow-string component 222, so that the clamping force of the clamping bow-string component 222 can be adjusted, and the clamping force of the headset can be changed according to actual requirements.

However, during the process of unfolding the clamping bow-shaped arm 222, the holding between the clamping bow-shaped arm 222 and the inner wall of the flexible headset housing 210 needs time, for example, when the headset needs to be clamped, the clamping bow-shaped arm 222 is initially in contact with the first inner wall of the flexible headset housing 210, and then under the pushing of the clamping bow-shaped piece 224, the clamping bow-shaped arm 222 is in contact with the second inner wall of the flexible headset housing 210, and the first inner wall and the second inner wall of the flexible headset housing 210 are arranged opposite to each other. In this process, the change of the clamping force of the clamping bow arm 222 takes a certain time, and the clamping cannot be rapidly realized, i.e. the clamping force cannot be rapidly increased, and this phenomenon is particularly remarkable at the end of the clamping bow arm 222, i.e. the change of the clamping force is slower the farther away the clamping bow arm 222 is from the clamping bow 224.

In order to increase the increase rate of the clamping force, please refer to fig. 3, the clamping bow arm 222 further includes a first clamping bow arm elastic sheet 2222 and a second clamping bow arm elastic sheet 2224 which are stacked, a bending radius of the first clamping bow arm elastic sheet 2222 is smaller than a bending radius of the second clamping bow arm elastic sheet 2224, the first clamping bow arm elastic sheet 2222 and the second clamping bow arm elastic sheet 2224 are both inserted into the guide groove 224b, one surface of the first clamping bow arm elastic sheet 2222 departing from the second clamping bow arm elastic sheet 2224 is slidably abutted to the bow string body 2242, and one surface of the second clamping bow arm elastic sheet 2224 departing from the first clamping bow arm elastic sheet 2222 is slidably abutted to the second guide plate 2246.

In this embodiment, the first clamping arm spring 2222 and the second clamping arm spring 2224 are stacked, for example, the first clamping arm spring 2222 is disposed close to the speaker device 100, and the second clamping arm spring 2224 is located on a surface of the first clamping arm spring 2222 deviating from the speaker device 100, that is, the second clamping arm spring 2224 is stacked on the first clamping arm spring 2222. The first clamping bow-arm elastic sheet 2222 and the second clamping bow-arm elastic sheet 2224 are both of a bending structure to match the structure of the head-wearing flexible shell 210, i.e. match the shape of the head of a human body, so that the bending direction of the first clamping bow-arm elastic sheet 2222 and the second clamping bow-arm elastic sheet 2224 faces the head of the human body, and the head-wearing flexible shell 210 can apply enough clamping force. Specifically, the bending radius of the first clamping arm spring 2222 is set to be smaller than the bending radius of the second clamping arm spring 2224, such that the distance between the end of the first clamping arm spring 2222 from the middle to the second clamping arm spring 2224 is gradually increased, and thus the first clamping arm spring 2222 is folded inward compared to the second clamping arm spring 2224, that is, the end of the first clamping arm spring 2222 is closer to the head of the human body. The distance between the middle-to-end portion of the first clamping bow arm elastic sheet 2222 and the second clamping bow arm elastic sheet 2224 is gradually increased, and the clamping bow string piece 224 attenuates the increase of the clamping force when the clamping bow arm piece 222 is folded, that is, the increase of the clamping force in the folded state is gradually decreased, so that the finally required clamping force can be finely adjusted, and the excessive extrusion on the head of the human body in the process of adjusting the clamping force is effectively reduced.

Thus, under the condition that the first clamping arm spring 2222 and the second clamping arm spring 2224 are all penetrated into the guide groove 224b, the contact point of the first clamping arm spring 2222 and the bowstring body 2242 is a supporting point, the contact point of the second clamping arm spring 2224 and the second guide plate 2246 is a retracting point, when the middle part of the clamping arm 224 is gradually far away from the installation hole 212, namely, the clamping arm 222 is gradually retracted, at the beginning, the second clamping arm spring 2224 is in contact with the shell of the head-wearing flexible shell 210, the second guide plate 2246 extrudes the second clamping arm spring 2224, so that the second clamping arm spring 2224 moves towards the first clamping arm spring 2222. In the guide slot 224b, the contact point between the first clamping arm spring 2222 and the bowstring body 2242 is used as a supporting point, so that the bending deformation of the second clamping arm spring 2224 can be rapidly transmitted to the first clamping arm spring 2222 through the supporting point, and the first clamping arm spring 2222 can rapidly respond to the deformation of the second clamping arm spring 2224, so that the deformation response rate of the first clamping arm spring 2222 can be increased, and the extrusion of the first clamping arm spring 2222 on the head-wearing flexible shell 210 can be effectively increased, so that the clamping force generated by the deformation of the second clamping arm spring 2224 can be rapidly transmitted to the first clamping arm spring 2222, and the clamping force of the head-wearing earphone can be rapidly increased.

In another embodiment, referring to fig. 3, the clamping bow arm 222 further includes a third clamping bow arm spring 2226, the third clamping bow arm spring 2226 is located between the first clamping bow arm spring 2222 and the second clamping bow arm spring 2224, a bending radius of the third clamping bow arm spring 2226 is greater than a bending radius of the first clamping bow arm spring 2222, and a bending radius of the third clamping bow arm spring 2226 is smaller than a bending radius of the second clamping bow arm spring 2224. The third clamping arm elastic sheet 2226 serves as an auxiliary elastic sheet, and the gap between the first clamping arm elastic sheet 2222 and the second clamping arm elastic sheet 2224 is filled in the bending groove 222a, so that the clamping force generated by the deformation of the first clamping arm elastic sheet 2222 can be rapidly transmitted to the second clamping arm elastic sheet 2224, and the response speed of the clamping force of the headset can be further improved.

Further, when the second clamping arm spring 2224 presses the first clamping arm spring 2222 through the third clamping arm spring 2226, there is a situation that the adjusting member 226 rotates too fast, which easily causes the clamping arm member 222 to be folded too fast, and thus easily causes the ear muff 112 to snap to the ear of the user, causing explosion sound and causing damage to the eardrum. In order to reduce the possibility of the clamping bow arm 222 collapsing too fast, please refer to fig. 6, the headgear 200 further includes a resistor 230, wherein the resistor 230 includes a first connecting rod 232, a second connecting rod 234, a third connecting rod 236, a first resistor spring 238, a second resistor spring 231, a first rotating shaft 233, and a second rotating shaft 235; the first resistance-increasing spring 238 is respectively connected to the first connecting rod 232 and the third connecting rod 236, the first resistance-increasing spring 238 is sleeved on the first rotating shaft 233, and the first connecting rod 232 is connected to the first clamping bow spring 2222; the second resistance-increasing spring 231 is respectively connected to the second connecting rod 234 and the third connecting rod 236, the second resistance-increasing spring 231 is sleeved on the second rotating shaft 235, and the second connecting rod 234 is connected to the second clamping bow arm elastic sheet 2224; the first rotating shaft 233 and the second rotating shaft 235 are both connected to the third clamping arm elastic sheet 2226. In this embodiment, the first resistance-increasing spring 238 is connected to the third pantograph arm elastic piece 2226 by the first rotating shaft 233, the second resistance-increasing spring 231 is connected to the third pantograph arm elastic piece 2226 by the second rotating shaft 235, such that the first connecting rod 232 rotates around the first rotating shaft 233, the second connecting rod 234 rotates around the second rotating shaft 235, such that the first resistance-increasing spring 238 provides elastic resistance for the first connecting rod 232, the second resistance-increasing spring 231 provides elastic resistance for the second connecting rod 234, and such that the portion of the deformation force transmitted from the second pantograph arm elastic piece 2224 to the third pantograph arm elastic piece 2226 by the first resistance-increasing spring 238 and the second resistance-increasing spring 231 is split by the first resistance-increasing spring 238 and the second resistance-increasing spring 231, so as to reduce the closing rate of the pantograph arm 222, thereby effectively reducing the probability of the headset folding too fast and ensuring the normal use of the user. The third clamping bow arm elastic sheet is provided with a third through hole, the third connecting rod penetrates through the third through hole, so that the first connecting rod and the second connecting rod are located on two sides of the third clamping bow arm elastic sheet, the first connecting rod is abutted to the first clamping bow arm elastic sheet, and the second connecting rod is abutted to the second clamping bow arm elastic sheet.
