The elastic band 2122 is separated from the covering body 2121 between the two ends of the elastic band 2122 and the connection positions of the covering body 2121, and the elastic band 2122 is used to assist in positioning the clamping assembly 210 on the head of the user in a wearing state.

[0053] As shown in Figure 2 , the telescopic assembly 22 can include a fixed part 221 and a telescopic part 223 telescopically arranged relative to the fixed part 221.

The microphone assembly 80 is provided with at least one microphone and a related button, which can turn the microphone on or off.

[0059] In medicine, anatomy, and other fields, the human body can be defined by three basic planes: the sagittal plane, the coronal plane, and the horizontal plane; and three basic axes: the sagittal axis (SA), the coronal axis (CA), and the vertical axis (VA). The sagittal plane is a section perpendicular to the ground along the anteroposterior direction of the body, dividing the body into left and right parts. The coronal plane is a section perpendicular to the ground along the left-right direction of the body, dividing the body into anterior and posterior parts. The horizontal plane is a section parallel to the ground along the vertical direction of the body, dividing the body into superior and inferior parts. Correspondingly, the sagittal axis (SA) is the axis along the anteroposterior direction of the body and perpendicular to the coronal plane; the coronal axis is the axis along the left-right direction of the body and perpendicular to the sagittal plane; and the vertical axis (VA) is the axis along the vertical direction of the body and perpendicular to the horizontal plane. Figure 3 As shown, when the earphone 1 is worn, the wearing component 2 is clamped on both sides of the user's head, and the speaker component 3 is located in the facial area in front of the tragus along the sagittal axis SA.

[0060] The following content will describe in detail the headphone 1 or some of the components and structures mentioned above. Of course, some of the structures and components mentioned above, such as the bone conduction speaker 40 and the air conduction speaker 50, can be used not only in the headphone 1, but also in other electronic devices, such as mobile phones, speakers, and smart wearable devices.

[0061] The following describes an exemplary structure of the earphone 1 in the earphone embodiment of this application.

[0062] like Figures 4 to 7 As shown, in some embodiments, the earphone 1 includes a wearing component 2 and a speaker assembly 3 connected to the wearing component 2. The wearing component 2 is used to position the speaker assembly 3 on the facial area in front of the user's tragus when worn. The front of the tragus is the side of the tragus closest to the nose.

[0063] The speaker assembly 3, located in the facial area in front of the user's tragus, transmits sound to the user's ear via the speaker. There can be two speaker assemblies 3. The two speaker assemblies 3 are used to transmit vibrations and / or sound to the user's left and right ears, respectively. The two speaker assemblies 3 can be identical or different. Furthermore, the earphone 1 may also include a microphone assembly 7, which can be mounted on one of the speaker assemblies 3. The microphone assembly 7 can be used to trigger the operation of the speaker assembly 3, and it can also be used to collect sound. The speaker assembly 3 may include at least one of a bone conduction speaker and an air conduction speaker.

[0064] The wearing assembly 2 can hang the speaker assembly 3 on the face area in front of the user's tragus, and the wearing assembly 2 can also apply a force to the speaker assembly 3 so that the speaker assembly 3 is attached to the face area in front of the user's tragus. Specifically, the wearing assembly 2 is used to bypass the top of the user's head and can make the speaker assembly 3 as a whole located in front of the user's ear. The shape of the wearing assembly 2 can match the contour of the user's head, so that the user wears the earphone 1 more comfortably and stably.

[0065] The following is an exemplary structure of the wearing assembly 2 of the present application.

[0066] As shown in Figures 4 to 7 , the wearing assembly 2 can include a headband assembly 21, the headband assembly 21 including a clamping assembly 210, a wire 211b, and a first elastic covering body 212, the clamping assembly 210 having a length direction Lt, a thickness direction Ht, and a width direction Wt, the clamping assembly 210 being arranged in a curved shape along the length direction Lt so that the headband assembly 21 is arranged around the periphery of the top of the user's head in the wearing state and provides a clamping force, the clamping assembly 210 having a dimension along the width direction Wt greater than a dimension along the thickness direction Ht, and in the wearing state, the thickness direction Ht is directed towards or away from the user's head, and the first elastic covering body 212 includes a covering body 2121, the covering body 2121 being shaped to cover the periphery of the clamping assembly 210 and the wire 211b, and the clamping assembly 210 and the wire 211b located in the covering body 2121 are arranged at least partially overlapping along the thickness direction Ht. The clamping assembly 210 and the wire 211b arranged at least partially overlapping along the thickness direction Ht can mean that the clamping assembly 210 and the wire 211b are at least partially level with each other along the thickness direction Ht.

[0067] Specifically, the clamping assembly 210 can be deformed under the action of external force during the wearing of the headband assembly 21, stress can be generated inside the clamping assembly 210, so that the clamping assembly 210 has a clamping effect, thereby improving the wearing stability of the headband assembly 21.

[0068] By setting the dimension of the clamping assembly 210 along the width direction Wt to be greater than the dimension along the thickness direction Ht, the dimension of the clamping assembly 210 along the thickness direction Ht is smaller, so that when the clamping assembly 210 is deformed, it can have a relatively stable directional elastic deformation in the direction of clamping the user's head, reducing the elastic deformation of the clamping assembly 210 in the width direction Wt, thereby facilitating the molding of the clamping assembly 210, and at the same time making the headband assembly 21 easy to wear. The larger dimension of the clamping assembly 210 along the width direction Wt can make the clamping assembly 210 maintain sufficient clamping force, and at the same time be conducive to increasing the acting area of the clamping assembly 210 on the top of the user's head, so as to improve the wearing stability of the headband assembly 21.

[0069] The covering body 2121 can be made of an elastic material and has deformability, thus deforming synchronously with the clamping component 210. By molding the covering body 2121 around the clamping component 210 and the lead wire 211b, the assembly process of the headband component 21 can be simplified, and the structural stability of the headband component 21 can be improved. The covering body 2121 can also improve the tactile feel of the user contacting the headband component 21, improving the wearing comfort of the headband component 21. The elastic deformation of the covering body 2121 can also increase the friction between the user's head and the headband component 21, reducing the risk of slippage of the headband component 21 during wearing and improving wearing stability. For example, the covering body 2121 can be molded or compression molded around the clamping component 210 and the lead wire 211b. The headband component 21 can be made of materials such as silicone or rubber, for example, the covering body 2121 can be made of silicone or rubber.

[0070] The clamping assembly 210 has higher mechanical strength than the wire 211b. By at least partially overlapping the clamping assembly 210 and the wire 211b along the thickness direction Ht, the tensile or compressive effects on the wire 211b when the clamping assembly 210 deforms can be reduced, thereby improving the service life of the wire 211b. At the same time, the deformation consistency of the clamping assembly 210 and the wire 211b is high, improving the structural stability of the wearing assembly 2.

[0071] Optionally, such as Figure 7 and Figure 8 As shown, the ratio of the overlap dimension of the clamping assembly 210 and the wire 211b along the thickness direction Ht to the minimum of the dimensions of the clamping assembly 210 along the thickness direction Ht and the wire 211b along the thickness direction Ht is between 0.6 and 1. Optionally, this ratio can also be between 0.7 and 0.9.

[0072] Specifically, in some embodiments, the dimension of the clamping assembly 210 along the thickness direction Ht is greater than or equal to the dimension of the wire 211b along the thickness direction Ht, and the ratio of the overlap dimension of the clamping assembly 210 and the wire 211b along the thickness direction Ht to the dimension of the wire 211b along the thickness direction Ht is between 0.6 and 1. For example, the ratio of the overlap dimension of the clamping assembly 210 and the wire 211b along the thickness direction Ht to the dimension of the wire 211b along the thickness direction Ht is 0.7, 0.8, or 0.9.

[0073] In some embodiments, the size of the clamping assembly 210 along the thickness direction Ht is smaller than the size of the wire 211b along the thickness direction Ht, and the ratio of the overlapping size of the clamping assembly 210 and the wire 211b along the thickness direction Ht to the size of the clamping assembly 210 along the thickness direction Ht is between 0.6 and 1. For example, the ratio of the overlapping size of the clamping assembly 210 and the wire 211b along the thickness direction Ht to the size of the clamping assembly 210 along the thickness direction Ht is 0.7, 0.8, or 0.9.

[0074] In this way, the clamping assembly 210 and the wire 211b have more overlap along the thickness direction Ht, which is conducive to the deformation of the wire 211b and the clamping assembly 210 synchronously, reduces the stretching or extrusion of the wire 211b when the clamping assembly 210 deforms, and improves the service life of the wire 211b. Meanwhile, the clamping assembly 210 and the wire 211b have more overlap along the thickness direction Ht, which is conducive to reducing the size of the headband assembly 21 along the thickness direction Ht and promoting the overall lightness and thinness of the headband assembly 21. If the ratio is smaller, the stretching or extrusion of the wire 211b when the clamping assembly 210 deforms is too large, which is not conducive to the overall lightness and thinness of the headband assembly 21.

[0075] Optionally, as shown in Figure 7 and Figure 8 the ratio of the size of the clamping assembly 210 along the thickness direction Ht to the size of the wire 211b along the thickness direction Ht is between 0.5 and 2. Optionally, the ratio can be between 0.8 and 1.8. Optionally, the ratio can be between 1.1 and 1.6. For example, the ratio of the size of the clamping assembly 210 along the thickness direction Ht to the size of the wire 211b along the thickness direction Ht is 0.7, 0.9, 1.0, 1.2, 1.5, or 1.8. Optionally, the ratio of the size of the clamping assembly 210 along the thickness direction Ht to the size of the wire 211b along the thickness direction Ht is between 0.8 and 1.2.

[0076] If the ratio is smaller, the clamping assembly 210 and the wire 211b have less overlap along the thickness direction Ht, and the stretching or extrusion of the wire 211b when the clamping assembly 210 deforms is too large. If the ratio is larger, the size of the headband assembly 21 is larger and the weight is heavier, which reduces the wearing comfort of the user and is not conducive to the overall lightness and thinness of the headband assembly 21. Therefore, setting the above ratio range can make the size of the clamping assembly 210 along the thickness direction Ht and the size of the wire 211b along the thickness direction Ht be within a certain reasonable range, which is conducive to improving the deformation consistency of the clamping assembly 210 and the wire 211b, thereby reducing the stress of the wire 211b, while ensuring the overall lightness and thinness of the headband assembly 21.

[0077] Optionally, as shown in Figure 4 andFigure 5 As shown, the first elastic cover body 212 further comprises an elastic band 2122 integrally formed with the cover main body 2121, two ends of the elastic band 2122 are spaced apart from each other along the length direction Lt and are connected with the cover main body 2121 respectively, the elastic band 2122 is separated from the cover main body 2121 between the two ends of the elastic band 2122 and the connection positions of the cover main body 2121, and the elastic band 2122 is used to assist positioning of the clamping assembly 210 on the user's head in the wearing state.

[0078] The clamping assembly 210 is stiffer than the elastic band 2122, and the clamping assembly 210 has a smaller ability to bend and deform than the elastic band 2122. The elastic band 2122 has elasticity and is easy to fit the user's head, thereby increasing the wearing comfort. By providing the elastic band 2122, the headband assembly 21 can obtain more degrees of freedom in structure, can improve the covering effect of the headband assembly 21 on the user's head, and can further improve the friction between the headband assembly 21 and the user's head, thereby being able to improve the wearing stability of the headband assembly 21. The material of the elastic band 2122 itself can also increase the friction between the user's head and the headband assembly 21, reduce the risk of sliding of the headband assembly 21 during wearing, and improve the wearing stability. In addition, the elastic band 2122 can also provide clamping force when deformed to strengthen the clamping effect of the headband assembly 21.

[0079] By integrally forming the cover main body 2121 and the elastic band 2122, the assembly process can be simplified. By arranging the elastic band 2122 and the cover main body 2121 to be separated from each other, the elastic band 2122 can be more flexible when deformed, and the functional effect of the elastic sheet 2101 can be improved. Further, the elastic band 2122 and the cover main body 2121 can have a spacing therebetween to provide space for deformation of the elastic band 2122, and the elastic band 2122 is closer to the user's head, thereby improving the wearing stability.

[0080] For example, the cover main body 2121 and the elastic band 2122 are integrally formed by injection molding or mold pressing, etc. The material of the elastic band 2122 can include silicone, rubber, etc.

[0081] Optionally, as shown in Figure 7 and Figure 8 The wearing assembly 2 is used to position the speaker assembly 3 in the listening area of the user's ear or near the ear in the wearing state, and in the sagittal axis SA direction, the speaker assembly 3 is closer to the side of the face than the clamping assembly 210, and the wire 211b is closer to the back of the brain than the clamping assembly 210.

[0082] In this way, the clamping assembly 210 is arranged closer to the speaker assembly 3 along the sagittal axis SA, which is conducive to improving the positioning effect of the clamping assembly 210 on the speaker assembly 3, and makes the wearing of the speaker assembly 3 more stable. Moreover, the wire 211b is arranged closer to the back of the brain than the clamping assembly 210, so that the clamping assembly 210 is arranged closer to the front of the brain, and the strength of the clamping assembly 210 arranged closer to the front of the brain is higher, which can better clamp the head of the user, and can reduce the possibility of the headband assembly 21 slipping off when the user bends down.

[0083] Optionally, as shown in Figure 7 and Figure 8 , the clamping assembly 210 includes an elastic sheet 2101, and the wire 211b is arranged on the side of the elastic sheet 2101 along the width direction Wt and at least partially overlaps the elastic sheet 2101 along the thickness direction Ht.

[0084] In this way, the size of the headband assembly 21 along the thickness direction Ht is reduced, so that the headband assembly 21 is lightened and thinned as a whole. The sheet-shaped arrangement of the elastic sheet 2101 is easy to form in the manufacturing process and has a high yield. The size of the elastic sheet 2101 along the width direction Wt can be greater than the size along the thickness direction Ht. By arranging the elastic sheet 2101, strain and stress can be generated inside the elastic sheet 2101 during the wearing of the headband assembly 21, so that the elastic sheet 2101 has a clamping effect, thereby improving the wearing stability of the headband assembly 21.

[0085] By covering the elastic sheet 2101 and the wire 211b in a shaped manner with the covering body 2121, the assembly process of the headband assembly 21 can be simplified, and the structural stability of the headband assembly 21 can be improved. By arranging the elastic sheet 2101 and the wire 211b at least partially overlapping along the thickness direction Ht, the stretching or extrusion effect of the elastic sheet 2101 on the wire 211b when the elastic sheet 2101 deforms can be reduced, the deformation consistency of the elastic sheet 2101 and the wire 211b is high, the structural stability of the headband assembly 21 is improved, and the service life of the wire 211b is improved.

[0086] Further, the elastic sheet 2101 can be a titanium sheet, of course, it can also be a spring steel sheet, or it can be a carbon fiber sheet.

[0087] Optionally, the size of the elastic sheet 2101 along the thickness direction Ht ranges from 0.65 mm to 2 mm. Further, the size of the elastic sheet 2101 along the thickness direction Ht ranges from 0.8 mm to 1.6 mm or 1.65 mm to 1.8 mm, for example, the size of the elastic sheet 2101 along the thickness direction Ht is 0.83 mm, 0.85 mm, or 0.87 mm.

[0088] If the size of the elastic sheet 2101 along the thickness direction Ht is large, the size of the headband assembly 21 will be large and the weight will be heavy, which reduces the wearing comfort of the user and is not conducive to the overall lightness and thinness of the headband assembly 21. If the size of the elastic sheet 2101 along the thickness direction Ht is small, on the one hand, the elastic sheet 2101 cannot provide sufficient clamping force, and on the other hand, it will cause the elastic sheet 2101 to deform and the wire 211b to be subjected to excessive stretching or extrusion. Therefore, by setting the above size range, on the one hand, it is conducive to the overall lightness and thinness of the headband assembly 21, making the user wear comfortable, and on the other hand, it is conducive to the elastic sheet 2101 to play a role in clamping the user's head, reducing the stretching or extrusion of the wire 211b, so that the wire 211b can be protected when the elastic sheet 2101 deforms.

[0089] Optionally, the portion of the wire 211b inside the covering body 2121 includes a wire bundle, and the size of the wire bundle along the thickness direction Ht ranges from 1 to 2.5 mm. For example, the size of the portion of the wire bundle along the thickness direction Ht is 1.2-2 mm, for example, the size of the portion of the wire bundle along the thickness direction Ht is 1.2 mm, 1.3 mm, 1.5 mm or 1.6 mm.

[0090] Optionally, the portion of the wire 211b inside the covering body 2121 includes a wire bundle and an insulated wire bundle channel for covering the wire bundle. Optionally, the wire bundle is movably covered in the insulated wire bundle channel.

[0091] If the size of the wire 211b along the thickness direction Ht is large, the wire 211b will be easily stretched or extruded. If the size of the wire 211b along the thickness direction Ht is small, the mechanical strength and electrical conductivity of the wire 211b will be weak. Therefore, by setting the above size range, it is conducive to maintaining the wire 211b in a good and stable working state and prolonging the service life of the wire 211b.

[0092] Further, the portion of the wire 211b exposed outside is a wire bundle wrapped by an insulating skin, and the thickness of the portion of the wire bundle ranges from 1.6 to 2.4 mm, and further, the thickness of the portion of the wire bundle ranges from 1.8 mm, 2 mm, or 2.2 mm. The insulating skin can have the effects of insulation and aesthetics. By setting the above, the thickness of the insulating skin is moderate, which can improve the working stability of the insulating skin. If the insulating skin is too thin, the insulating skin will be easily damaged, and if the insulating skin is too thick, the insulating skin material will be wasted, and the appearance will be affected.

[0093] Optionally, during assembly, the wire 211b and the elastic sheet 2101 can be fixed by glue, and then the covering body 2121 can be used to cover the wire 211b and the elastic sheet 2101.

[0094] Optionally, as shown in Figure 7 , Figure 9 and Figure 10 , the clamping assembly 210 includes two elastic sheets 2101 arranged side by side along the width direction Wt, and the wire 211b is arranged between the two elastic sheets 2101 or on the side of one of the two elastic sheets 2101 away from the other along the width direction Wt, and at least partially overlaps with the two elastic sheets 2101 along the thickness direction Ht respectively.

[0095] By arranging two elastic sheets 2101, the clamping force of the clamping assembly 210 can be enhanced, so that the clamping assembly 210 is easy to deform while obtaining sufficient clamping force, thereby improving the wearing effect. The wire 211b is arranged between the two elastic sheets 2101 or on the side of one of the two elastic sheets 2101 away from the other along the width direction Wt, which effectively protects the wire 211b due to the increase of strength and elasticity on the basis of providing sufficient support for the clamping assembly 210. Further, if the wire 211b is arranged between the two elastic sheets 2101 along the width direction Wt, the two elastic sheets 2101 can act as a support frame when the headband assembly 21 is deformed, thereby protecting the wire 211b.

[0096] Further, the wire 211b is arranged on the side of the two elastic sheets 2101 away from the speaker assembly 3 along the sagittal axis SA direction, thereby facilitating to improve the positioning effect of the clamping assembly 210 on the speaker assembly 3.

[0097] Optionally, as shown in Figure 7 and Figure 11 , the clamping assembly 210 includes two elastic sheets 2101 arranged in layers along the thickness direction Ht, and the wire 211b is clamped between the two elastic sheets 2101.

[0098] By arranging two elastic sheets 2101, the clamping assembly 210 can be easy to deform while obtaining sufficient clamping force, thereby improving the wearing effect. When the wire 211b is arranged between the two elastic sheets 2101 along the thickness direction Ht, the two elastic sheets 2101 can act as a support frame when the headband assembly 21 is deformed, thereby protecting the wire 211b and facilitating to improve the structural stability of the headband assembly 21.

[0099] Optionally, as shown in Figure 4 and Figure 12 , the two ends of the clamping assembly 210 are exposed from the first elastic cover 212, and the wearing assembly 2 further includes an extension assembly 22, and the extension assembly 22 is assembled and fixed with the ends of the clamping assembly 210 exposed from the first elastic cover 212.

[0100] The telescopic assembly 22 is connected between the speaker assembly 3 and the headband assembly 21, and is capable of telescoping under an external force. The telescopic assembly 22 is capable of changing in length through telescoping, so that the distance between the speaker assembly 3 and the headband assembly 21 is changed. By arranging the telescopic assembly 22, the structure of the wearing assembly 2 is more flexible. When the earphone 1 is worn by different users, the wearing assembly 2 can be adaptively adjusted according to the head shapes of the users, so that the speaker assembly 3 can be positioned at a proper position, and the compatibility of the wearing assembly 2 is improved.

[0101] The rigidity and hardness of the clamping assembly 210 are stronger than those of the first elastic covering 212. By arranging the telescopic assembly 22 to be assembled and fixed with the end of the clamping assembly 210 exposed from the first elastic covering 212, the assembly and connection of the telescopic assembly 22 and the headband assembly 21 are facilitated, and the connection effect is improved.

[0102] Optionally, as shown in Figure 4 , Figures 12 to 14 , the telescopic assembly 22 comprises a fixed part 221, a clamping part 222 and a telescopic part 223. The fixed part 221 is provided with a first insertion hole 2201 and a first clamping hole 2202 in communication with the first insertion hole 2201. The end of the clamping assembly 210 is inserted into the first insertion hole 2201, and the clamping part 222 is inserted into the first clamping hole 2202 and clamps the end of the clamping assembly 210 in the first insertion hole 2201.

[0103] In some embodiments, the telescopic part 223 is capable of changing in length by telescoping. In other embodiments, the telescopic part 223 is capable of moving relative to the fixed part 221 to change the length of the telescopic assembly 22.

[0104] In this way, the assembly and connection of the clamping assembly 210 and the telescopic assembly 22 are facilitated. For example, during assembly, the end of the clamping assembly 210 can be inserted into the first insertion hole 2201, and then the clamping part 222 is inserted into the first clamping hole 2202. For another example, the end of the clamping assembly 210 can be deformed and inserted into the first insertion hole 2201 by buckling.

[0105] Optionally, as shown in Figure 4 , Figures 12 to 14 , the telescopic assembly 22 further comprises a decorative part 224. The fixed part 221 is provided with a sliding groove 2203, and the telescopic part 223 is slidingly arranged in the sliding groove 2203. The first clamping hole 2202 and the sliding groove 2203 are arranged on the side of the fixed part 221 facing the user in the wearing state. The decorative part 224 is assembled and fixed with the fixed part 221 to cover the first clamping hole 2202, the sliding groove 2203 and the part of the telescopic part 223 located in the sliding groove 2203.

[0106] The telescopic part 223 is movable relative to the fixed part 221 along the extension direction of the sliding groove 2203. The decorative part 224 can shield the first clamping hole 2202, the sliding groove 2203 and the part of the telescopic part 223 located in the sliding groove 2203 to beautify the appearance. The decorative part 224 can also function as a limiting part when assembled with the fixed part 221 to limit the clamping part 222 from sliding out of the first clamping hole 2202 and limit the telescopic part 223 from sliding out of the sliding groove 2203.

[0107] Optionally, as shown in Figure 4 、 Figures 12 to 14 , the telescopic assembly 22 further comprises a damping part 227 fixed to the part of the telescopic part 223 located in the sliding groove 2203, and the damping part 227 also abuts against the decorative part 224. The telescopic part 223 is slidable under the action of an external force, and the damping part 227 is used to increase the sliding resistance of the telescopic part 223 when sliding between the decorative part 224 and the fixed part 221, so that the telescopic part 223 can stay at the position after sliding. Further, the damping part 227 is embedded in the part of the telescopic part 223 located in the sliding groove 2203.

[0108] Optionally, as shown in Figure 4 、 Figures 12 to 14 , the end of the clamping assembly 210 is provided in a sheet shape, and a second clamping hole 2102 is provided through the two side main surfaces of the end of the clamping assembly 210. When the end of the clamping assembly 210 is inserted into the first insertion hole 2201, the first clamping hole 2202 and the second clamping hole 2102 are aligned, the clamping part 222 is a pin column inserted into the first clamping hole 2202 and the second clamping hole 2102, and the first elastic cover 212 further comprises an embedded part 2123 integrally formed with the cover main body 2121, which is attached to one side main surface of the end of the clamping assembly 210. The fixed part 221 is provided with a second insertion hole 2204 in communication with the first insertion hole 2201, and the embedded part 2123 is inserted into the second insertion hole 2204.

[0109] By providing the end of the clamping assembly 210 in a sheet shape, the shape of the end of the clamping assembly 210 can match the shape of the part of the clamping assembly 210 located in the cover main body 2121, thereby facilitating the molding of the clamping assembly 210 and the second clamping hole 2102. By providing the clamping part 222 as a pin column inserted into the first clamping hole 2202 and the second clamping hole 2102, the connection firmness of the end of the clamping assembly 210 and the fixed part 221 can be improved.

[0110] By attaching the embedded portion 2123 to the side main surface of the end portion of the clamping assembly 210, the embedded portion 2123 can limit the relative movement of the end portion of the clamping assembly 210 and the fixed portion 221 in the direction perpendicular to the main surface of the end portion of the clamping assembly 210, and can also limit the deformation of the end portion of the clamping assembly 210, thereby reducing the risk of breakage of the end portion of the clamping assembly 210, and enhancing the stability of the connection structure of the end portion of the clamping assembly 210 and the fixed portion 221.

[0111] For example, the cladding body 2121 and the embedded portion 2123 are integrally formed by injection molding or mold pressing, etc.

[0112] Optionally, as shown in Figure 4 , Figure 14 and Figure 15 , the telescopic assembly 22 includes a fixed portion 221 and a telescopic portion 223 telescopically arranged relative to the fixed portion 221, and the wearing assembly 2 further includes a torsion assembly 23, the torsion assembly 23 includes an elastic connecting member 231, one end of the elastic connecting member 231 is connected with the telescopic portion 223, and the other end of the elastic connecting member 231 is used for connecting the speaker assembly 3, and the elastic connecting member 231 is arranged to be able to be twisted in the wearing state due to the contact between the speaker assembly 3 and the user's head.

[0113] By arranging the elastic connecting member 231 to connect the telescopic assembly 22 and the speaker assembly 3, the speaker assembly 3 can have more degrees of freedom of movement relative to the headband assembly 21, and the speaker assembly 3 can better fit the user's head by moving relative to the headband assembly 21, thereby improving the user's wearing comfort. After adjusting the position of the telescopic portion 223 relative to the fixed portion 221, the speaker assembly 3 can better fit the user's head by moving relative to the telescopic portion 223, thereby improving the compatibility of the wearing assembly 2 for different users.

[0114] Optionally, as shown in Figure 15 , the elastic connecting member 231 is an elastic metal wire.

[0115] In this way, the elastic connecting member 231 has good structural strength and fatigue resistance, thereby improving the service life of the elastic connecting member 231. For example, the elastic metal wire can be a titanium wire.

[0116] Optionally, as shown in Figure 6 , Figure 14 and Figure 15 , the wire 211b extends from the outside of the telescopic assembly 22 to the torsion assembly 23 and is fixed to the torsion assembly 23, and the length of the wire 211b outside the telescopic assembly 22 is greater than the maximum elongation of the telescopic assembly 22.

[0117] Compared with arranging the wire 211b inside the telescopic assembly 22, arranging the wire 211b outside the telescopic assembly 22 can avoid the telescopic assembly 22 interfering with the wire 211b during the telescoping process, and is also conducive to reducing the size of the telescopic assembly 22 to improve the aesthetics and make the earphone as a whole lighter.

[0118] The twisting assembly 23 can guide the wire 211b to the inside of the speaker assembly 3. By fixing the wire 211b to the twisting assembly 23, the twisting assembly 23 can limit the wire 211b, thereby facilitating the wire 211b inside the speaker to remain stable.

[0119] The maximum extension of the telescopic assembly 22 is the length when the telescopic assembly 22 is fully extended. By arranging the length of the wire 211b outside the telescopic assembly 22 to be greater than the maximum extension of the telescopic assembly 22, the telescoping process of the telescopic assembly 22 can reduce the pulling of the wire 211b, thereby improving the service life of the wire 211b, and also reducing the interference of the wire 211b to the telescoping process of the telescopic assembly 22.

[0120] Further, the end of the telescopic assembly 22 connected to the twisting assembly 23 is provided with a hole, and the wire 211b extends from the outside of the telescopic assembly 22 into the hole and then extends into the twisting assembly 23 through the hole.

[0121] Optionally, as shown in Figure 6 , Figure 14 and Figure 15 , the twisting assembly 23 includes a second elastic covering body 232, the second elastic covering body 232 is formed around the elastic connecting piece 231, and is provided with a wire channel 230, and the wire 211b is arranged in the wire channel 230.

[0122] The second elastic covering body 232 can be partially or entirely covered on the twisting assembly 23. The second elastic covering body 232 has a deformation capability and can be twisted synchronously with the elastic wire. By forming the second elastic covering body 232 around the elastic connecting piece 231, the contact feeling of the twisting assembly 23 can be improved, the exposed length of the wire 211b can be reduced, and the appearance of the twisting assembly 23 can be beautified.

[0123] The wire 211b can extend to the inside of the speaker assembly 3 through the twisting assembly 23. By arranging the wire channel 230, the twisting assembly 23 can limit the wire 211b, thereby facilitating the wire 211b inside the speaker to remain stable.

[0124] For example, the second elastic cover 232 covers the periphery of the elastic connecting piece 231 in a molding manner such as injection molding or compression molding, and forms the wire channel 230.

[0125] The following is an exemplary structure of the wearing assembly 2 of the present application.

[0126] As shown in Figure 5 , Figure 14 and Figure 15 , in some embodiments, the wearing assembly 2 includes a headband assembly 21 and a torsion assembly 23, the headband assembly 21 includes a clamping assembly 210 arranged in a curved shape along the length direction Lt so that the headband assembly 21 is arranged around the periphery of the user's head in the wearing state and provides a clamping force, and the torsion assembly 23 includes an elastic connecting piece 231 including a first connecting segment 2311 and a second connecting segment 2312 connected to each other, the free end of the first connecting segment 2311 is connected to the clamping assembly 210, and the free end of the second connecting segment 2312 is connected to the speaker assembly 3 to position the speaker assembly 3 in the listening area near or on the user's ear in the wearing state, wherein starting from the free end of the first connecting segment 2311, the first connecting segment 2311 has an extension component extending along the sagittal axis SA toward the front side of the face, and the second connecting segment 2312 has an extension component extending along the vertical axis VA away from the crown, and the elastic connecting piece 231 is arranged to be able to produce torsion when the speaker assembly 3 contacts the user's head in the wearing state.

[0127] The free end of the first connecting segment 2311 is the end of the first connecting segment 2311 away from the second connecting segment 2312, and the free end of the second connecting segment 2312 is the end of the second connecting segment 2312 away from the first connecting segment 2311. Specifically, the clamping assembly 210 can play a supporting and shaping role in the headband assembly 21, by arranging the clamping assembly 210 in a curved shape along the length direction Lt, the shape of the headband assembly 21 can be matched with the contour of the user's head, and the user can wear the headband assembly 21 more comfortably and stably. During the wearing process of the headband assembly 21, the clamping assembly 210 can be deformed under the action of external force, stress can be generated inside the clamping assembly 210, so that the clamping assembly 210 has a clamping effect, thereby improving the wearing stability of the headband assembly 21.

[0128] By arranging the elastic connecting piece 231 to connect the clamping assembly 210 and the speaker assembly 3, the speaker assembly 3 can have more degrees of freedom of motion, and when the speaker assembly 3 is positioned in the face area, it can produce torsional motion relative to the headband assembly 21 through the elastic connecting piece 231, thereby being more closely fitted to the user's face, and being able to adapt to different head shapes and face shapes, thereby improving the wearing comfort of the user, and at the same time improving the compatibility of the earphone 1 to the user's head shape and face shape.

[0129] By setting the first connecting segment 2311 to have an extension component extending along the sagittal axis SA towards the front side of the face, and setting the second connecting segment 2312 to have an extension component extending along the vertical axis VA away from the top of the head, on the one hand, the loudspeaker assembly 3 can be positioned more stably in the listening area near the user's ear, so that the positioning of the loudspeaker assembly 3 is more stable and the sound effect is better; on the other hand, the above-mentioned connecting structure is simple in structure, and the first connecting segment 2311 and the second connecting segment 2312 can be twisted in different directions respectively, so that the elastic connecting piece 231 has more degrees of freedom of movement, which can improve the torsional deformation ability of the elastic connecting piece 231, facilitate the loudspeaker assembly 3 to better adapt to the head shape and face shape of the user, to fit the ear of the user or the listening area near the ear of the user, and is conducive to simplifying the structure of the elastic connecting piece 231.

[0130] In some embodiments, the first connecting segment 2311 can be twisted around the sagittal axis SA, so that the loudspeaker assembly 3 is twisted around the sagittal axis SA, and the second connecting segment 2312 can be twisted around the vertical axis VA, so that the loudspeaker assembly 3 is twisted around the vertical axis VA, so that the loudspeaker assembly 3 has more degrees of freedom of movement.

[0131] Optionally, as shown in Figure 5 , Figure 14 and Figure 15 , the second connecting segment 2312 is connected at an obtuse angle with the first connecting segment 2311, and in the wearing state, the included angle a1 between the second connecting segment 2312 and the vertical axis VA is smaller than the included angle a2 between the first connecting segment 2311 and the vertical axis VA.

[0132] In this way, the extension path of the elastic connecting piece 231 from the clamping assembly 210 to the loudspeaker assembly 3 can be kept away from the user's ear, improving the wearing comfort, and at the same time, the loudspeaker assembly 3 can be closer to the front side of the face along the sagittal axis SA than the headband assembly 21, so that when the loudspeaker assembly 3 is positioned in the listening area near the user's ear, the headband assembly 21 can also be in the area on the top of the user's head that can stably wear the headband assembly 21, thereby improving the wearing stability of the wearing assembly 2 and the positioning effect of the loudspeaker assembly 3.

[0133] The extension direction D22 of the first connecting segment 2311 and the extension direction D21 of the second connecting segment 2312 are different, so that the first connecting segment 2311 and the second connecting segment 2312 can be twisted in different directions respectively, and the elastic connecting piece 231 thereby has more degrees of freedom of movement, so that the torsional deformation ability of the elastic connecting piece 231 can be improved, and the loudspeaker assembly 3 can be adjusted in position. In some embodiments, the included angle a2 between the first connecting segment 2311 and the vertical axis VA is larger, which is conducive to the rotation of the loudspeaker assembly 3 around the sagittal axis SA to adjust the position.

[0134] The second connecting segment 2312 has a smaller angle a1 with the vertical axis VA, which is beneficial for adjusting the position of the loudspeaker assembly 3 around the vertical axis VA.

[0135] Optionally, as shown in Figure 5 , Figure 14 and Figure 15 , the wearing assembly 2 comprises a telescopic assembly 22, the telescopic assembly 22 comprises a fixed part 221 and a telescopic part 223, the fixed part 221 is connected with the end of the clamping assembly 210, the telescopic part 223 is telescopically arranged relative to the fixed part 221, and the free end of the first connecting segment 2311 is connected with one end of the telescopic part 223 away from the clamping assembly 210.

[0136] The telescopic assembly 22 is connected between the loudspeaker assembly 3 and the headband assembly 21, and the telescopic assembly 22 can be telescopically arranged under the action of an external force. The telescopic assembly 22 can change in length through telescopic arrangement, so that the distance between the loudspeaker assembly 3 and the headband assembly 21 changes. By arranging the telescopic assembly 22, the structure of the wearing assembly 2 is more flexible. When different users wear the earphone 1, the wearing assembly 2 can be adaptively adjusted according to the head shape and head size of the user, so as to be able to position the loudspeaker assembly 3 at a suitable position, thereby improving the compatibility of the wearing assembly 2.

[0137] Optionally, as shown in Figure 5 , Figure 14 and Figure 15 , the fixed part 221 is provided with a sliding groove 2203, the telescopic part 223 comprises a first telescopic segment 2231 and a second telescopic segment 2232, the first telescopic segment 2231 is slidingly arranged in the sliding groove 2203, the second telescopic segment 2232 is connected with the first telescopic segment 2231 at an obtuse angle, in the wearing state, the second telescopic segment 2232 has an angle a3 with the vertical axis VA which is larger than an angle a4 of the first telescopic segment 2231 with the vertical axis VA, and the free end of the first connecting segment 2311 is connected with the free end of the second telescopic segment 2232.

[0138] By arranging the second telescopic segment 2232 and the first telescopic segment 2231 to be connected at an obtuse angle, the telescopic part 223 has a streamlined structure, the second telescopic segment 2232 and the first telescopic segment 2231 transition naturally, and the overall structure can be improved in appearance.

[0139] The telescopic part 223 can move relative to the fixed part 221 along the extension direction of the sliding groove 2203. The extension direction D24 of the first telescopic segment 2231 can be consistent with the extension direction of the sliding groove 2203, so as to allow the telescopic part 223 to slide along the extension direction of the sliding groove 2203. The extension direction D23 of the second telescopic segment 2232 can be close to or consistent with the extension direction D22 of the first connecting segment 2311, so that the free end of the first connecting segment 2311 and the free end of the second telescopic segment 2232 can be aligned for connection.

[0140] By setting the included angle a3 between the second telescopic segment 2232 and the vertical axis VA to be greater than the included angle a4 between the first telescopic segment 2231 and the vertical axis VA, the included angle a4 between the first telescopic segment 2231 and the vertical axis VA can be smaller, and the included angle a3 between the second telescopic segment 2232 and the vertical axis VA can be greater. Since the included angle a4 between the first telescopic segment 2231 and the vertical axis VA is smaller, when the telescopic part 223 slides relative to the fixed part 221, the loudspeaker assembly 3 can produce a larger displacement in the direction of the vertical axis VA, thereby being more compatible with the head shape and face shape of the user. Since the included angle a3 between the second telescopic segment 2232 and the vertical axis VA is greater, the second telescopic segment 2232 can produce an extension component in the direction of the sagittal axis SA, thereby facilitating positioning of the loudspeaker assembly 3 in the listening area of the user's ear or near the ear. Specifically, the loudspeaker assembly 3 is closer to the front side of the face along the direction of the sagittal axis SA than the headband assembly 21, and the included angle a3 between the second telescopic segment 2232 and the vertical axis VA can cause the second telescopic segment 2232 to have a greater extension component in the direction of the sagittal axis SA, which is conducive to connection of the loudspeaker assembly 3 and the headband assembly 21 along the direction of the sagittal axis SA.

[0141] In some embodiments, the included angle a2 between the first connecting segment 2311 and the vertical axis VA is greater, and the included angle between the fixed part 221 and the vertical axis VA is smaller. By setting the included angle a3 between the second telescopic segment 2232 and the vertical axis VA to be greater than the included angle a4 between the first telescopic segment 2231 and the vertical axis VA, the assembly and connection between the telescopic part 223 and the fixed part 221 and the elastic connecting piece 231 can be facilitated.

[0142] Optionally, as shown in Figure 7 , Figure 14 and Figure 15 , the headband assembly 21 further includes a wire 211b and a first elastic covering body 212. The first elastic covering body 212 includes a covering main body 2121 which is covered on the periphery of the clamping assembly 210 and the wire 211b in a formed manner. Both ends of the wire 211b extend out of the covering main body 2121, and the wire 211b extends from the outside of the telescopic assembly 22 to the torsion assembly 23 and is fixed on the torsion assembly 23. The length of the wire 211b outside the telescopic assembly 22 is greater than the maximum extension amount of the telescopic assembly 22. Figure 14 andFigure 15 The wire 211b shown in the middle only shows a segment of the wire 211b and does not limit the shape and length of the wire 211b.

[0143] The headband assembly 21 is connected with a telescopic assembly 22 at each end. The covering body 2121 can limit and protect the wire 211b and guide the wire 211b to extend from the outside of one telescopic assembly 22 to the outside of the other telescopic assembly 22. Compared with arranging the wire 211b inside the telescopic assembly 22, arranging the wire 211b outside the telescopic assembly 22 can avoid interference between the telescopic assembly 22 and the wire 211b during the telescoping process, and at the same time, it is beneficial to reduce the size of the telescopic assembly 22 to improve the aesthetic appearance.

[0144] The twisting assembly 23 can guide the wire 211b to the inside of the speaker assembly 3. By fixing the wire 211b on the twisting assembly 23, the twisting assembly 23 can limit the wire 211b, thereby facilitating the position of the wire 211b inside the speaker to remain stable. For example, it can reduce the interference of the telescoping process of the telescopic assembly 22 on the position of the wire 211b inside the speaker assembly 3.

[0145] Optionally, as shown in Figure 14 and Figure 15 , the twisting assembly 23 further includes a first connector 233 and a second connector 234 arranged at both ends of the elastic connecting piece 231, the first connector 233 is connected and matched with the speaker assembly 3, and the second connector 234 is connected and matched with the free end of the second telescopic segment 2232.

[0146] The first connector 233 and the second connector 234 can position both ends of the elastic connecting piece 231. By arranging the first connector 233 and the second connector 234, the assembly structure can be simplified, the assembly connection of the elastic connecting piece 231 with the speaker assembly 3 and the telescopic assembly 22 can be facilitated, and the assembly efficiency can be improved. Further, the second connector 234 is inserted into the inside of the free end of the second telescopic segment 2232 and is fixed to the free end of the second telescopic segment 2232 by a pin or a threaded fastener 226.

[0147] Optionally, as shown in Figure 14 and Figure 15 , the speaker assembly 3 includes a main housing 31, the main housing 31 is provided with a connector hole 310, the second elastic covering body 232 and the first connector 233 are inserted into the connector hole 310, and the wire outlet of the wire channel 230 is located in the connector hole 310.

[0148] The main shell 31 can shield the end of the second elastic covering body 232 and the end of the first connector 233, thereby improving the aesthetics of the wearing assembly 2. By locating the wire outlet of the wire channel 230 in the connector hole 310, the wire 211b can be shielded to improve the aesthetics, and the wire 211b can be conveniently introduced into the speaker for connection during assembly.

[0149] Optionally, as shown in Figure 5 、 Figure 14 and Figure 15 , the end of the second elastic covering body 232 is provided with a flange part 2321, the connector hole 310 includes a first hole section 3101 and a second hole section 3102 which are in communication with each other, the second hole section 3102 is closer to the inside of the main shell 31 than the first hole section 3101, and the hole diameter of the first hole section 3101 is greater than that of the second hole section 3102, the flange part 2321 is inserted into the first hole section 3101 and the cross section perpendicular to the insertion direction is adapted to the cross section of the first hole section 3101, the first connector 233 extends from the end surface of the flange part 2321 and is inserted into the second hole section 3102, and the wire outlet of the wire channel 230 is located at the end surface of the flange part 2321.

[0150] The flange part 2321 can enhance the structural strength of the end of the second elastic covering body 232, and after the flange part 2321 is inserted into the first hole section 3101, the end of the torsion assembly 23 can be limited to have relative displacement with the speaker assembly 3 perpendicular to the insertion direction.

[0151] By extending the first connector 233 from the end surface of the flange part 2321 and inserting it into the second hole section 3102, the first connector 233 can be fixed to the main shell 31 to limit the disengagement of the torsion assembly 23 from the main shell 31, thereby improving the stability of the connection structure between the end of the torsion assembly 23 and the speaker assembly 3.

[0152] Optionally, as shown in Figure 14 and Figure 15 , a U-shaped insert 3103 can be arranged in the main shell 31, the U-shaped insert 3103 is inserted into the first connector 233 through the hole wall of the second hole section 3102 to fix the first connector 233 to the main shell 31.

[0153] Optionally, as shown in Figure 7 and Figure 14 , the telescopic assembly 22 further includes a holding part 225 which is relatively fixed with the fixing part 221, and the wire 211b outside the telescopic assembly 22 is held on the holding part 225.

[0154] By setting the retaining portion 225, the wire 211b can be limited from interfering with other parts of the wearing assembly 2, and the aesthetic appearance can be improved.

[0155] For example, the retaining portion 225 is a clip or a button. For another example, the retaining portion 225 is provided with a hole, and the wire 211b is arranged to pass through the hole and thus retained on the retaining portion 225.

[0156] Optionally, the wire 211b is arranged to move relative to the retaining portion 225 along with the extension and retraction of the telescopic portion 223.

[0157] In this way, the wire 211b can move away from the speaker assembly 3 in the retaining portion 225 during the retraction of the telescopic assembly 22, and the wire 211b can move towards the speaker assembly 3 in the retaining portion 225 during the extension of the telescopic assembly 22, so that the wire 211b can be prevented from being pulled during the extension and retraction, the stress on the wire 211b can be reduced, and the service life of the wire 211b can be improved.

[0158] The following is an exemplary structure of the boom microphone assembly 7 and the like of the earphone embodiment of the present application.

[0159] As shown in FIGS. Figure 4 , Figure 16 and Figure 17 In some embodiments, the earphone 1 can include a wearing assembly 2, a speaker assembly 3, and a boom microphone assembly 7. The wearing assembly 2 is connected to the speaker assembly 3, and the boom microphone assembly 7 is rotatably arranged on the speaker assembly 3 about a predetermined axis Ax3. The boom microphone assembly 7 includes a boom body assembly 70 and a microphone assembly 80. The microphone assembly 80 is fixedly connected to the boom body assembly 70. The boom body assembly 70 is used to position the microphone assembly 80 in a sound pickup area corresponding to a person's mouth when the earphone 1 is in a wearing state. The boom body assembly 70 includes an elastic sheet 71 and an elastic cover 72, the elastic cover 72 covers the elastic sheet 71, the elastic sheet 71 has a thickness direction Hm and a width direction Wm perpendicular to each other, and the size of the elastic sheet 71 in the thickness direction Hm is smaller than the size of the elastic sheet 71 in the width direction Wm. The thickness direction Hm is arranged towards or away from a person's face in the wearing state.

[0160] The speaker assembly 3 can deliver sound to a person's ear. The wearing assembly 2 can hang the speaker assembly 3 beside the user's ear, and can also give the speaker assembly 3 an acting force to make the speaker assembly 3 adhere to the facial area beside the user's ear. Specifically, the wearing assembly 2 is used to pass over the user's head, and can make the speaker assembly 3 as a whole located in front of the user's ear. The shape of the wearing assembly 2 can match the contour of the user's head, so that the user can wear the earphone 1 more comfortably and stably.

[0161] The microphone assembly 80 can capture the sound emitted by the mouth of the human, thereby collecting the voice of the user. The stick assembly 70 can be connected between the microphone assembly 80 and the speaker assembly 3, and by controlling the movement of the stick assembly 70, the microphone assembly 80 can be controlled to be in different positions and postures. For example, when the microphone assembly 80 is used, the stick assembly 70 can be controlled to move the microphone assembly 80 away from the sound pickup area and close to the wearing assembly 2, so that the microphone assembly 80 is in a storage position.

[0162] The elastic covering body 72 can improve the touch feeling of the user contacting the earphone 1 and improve the wearing comfort of the earphone 1. For example, the elastic covering body 72 is covered on the elastic sheet 71 in a way of injection molding or mold pressing.

[0163] During the use of the microphone assembly 80, the elastic sheet 71 can be deformed under the action of external force, and the elastic covering body 72 has the ability to deform and can be deformed synchronously with the elastic sheet 71, so that the structure of the stick assembly 70 is more flexible. When different users wear the earphone 1, the shape and position of the stick assembly 70 can be adjusted according to the head shape of the user, so that the microphone assembly 80 can be positioned at a suitable position. In this way, the microphone assembly 80 can have more degrees of freedom of movement to more reasonably capture sound, thereby improving the compatibility of the earphone 1, and at the same time, the wearing comfort of the user can be improved.

[0164] By setting the size of the elastic sheet 71 in the thickness direction Hm to be smaller than the size in the width direction Wm and setting the thickness direction Hm to face or be away from the human face in the wearing state, the size HD1 of the elastic sheet 71 in the thickness direction Hm is smaller, so that when the elastic sheet 71 deforms, it tends to deform in the thickness direction Hm, which facilitates adjusting the distance between the stick microphone assembly 7 and the human face and mouth to meet different sound capturing needs. The size WD1 of the elastic sheet 71 in the width direction Wm is larger, so that the elastic sheet 71 is not easy to deform in the width direction Wm, and a relatively stable directional elastic deformation in the thickness direction Hm can be achieved, and at the same time, the elastic sheet 71 can maintain sufficient support and shaping ability, thereby improving the positioning stability of the microphone assembly 80.

[0165] Optionally, as shown in Figure 16 and Figure 17 , the stick assembly 70 can rotate relative to the speaker assembly 3 about a preset axis Ax3. The elastic sheet 71 includes two side edges arranged opposite to each other in the width direction Wm, and the elastic sheet 71 is arranged such that when rotating in the rotation direction about the preset axis Ax3, one side edge of the two side edges is located in front of the rotation direction, and the other side edge is located behind the rotation direction.

[0166] By setting the stick body assembly 70 to be rotatable relative to the loudspeaker assembly 3 about the preset axis Ax3, due to the large size of the width direction Wm, one side edge is located in front and the other side edge is located in the rear, and the stick body assembly 70 is not easy to elastically deform when being pushed in the width direction Wm, so that the microphone assembly 80 can be oriented and rotated about the preset axis Ax3, thereby having a larger range of motion to meet different sound capturing requirements. By rotating the stick body assembly 70 relative to the loudspeaker assembly 3 about the preset axis Ax3, the microphone assembly 80 can also be switched between the storage position and the working position.

[0167] In addition, by setting the elastic sheet 71 to have one side edge of the two side edges located in front of the rotation direction and the other side edge located in the rear of the rotation direction when being rotated about the preset axis Ax3, the rotation direction of the elastic sheet 71 can be made different from the deformation direction, so as to further expand the movement freedom and range of motion of the microphone assembly 80 to meet more sound capturing requirements.

[0168] Optionally, as shown in Figure 18 , the included angle β1 between the width direction Wm and the preset axis Ax3 is ≥80° and ≤90°. For example, the included angle β1 between the width direction Wm and the preset axis Ax3 is 82°, 84°, 85° or 87°.

[0169] In this way, the rotation direction of the elastic sheet 71 can be made to differ greatly from the deformation direction, and thus the range of motion of the microphone assembly 80 is larger, and the microphone assembly 80 can have more postures to meet more sound capturing requirements. If the included angle β1 between the width direction Wm and the preset axis Ax3 is less than 80°, the rotation direction of the elastic sheet 71 is close to the deformation direction, and thus the range of motion of the microphone assembly 80 is limited.

[0170] Optionally, as shown in Figure 16 and Figure 19 , the rotation angle range of the stick body assembly 70 in the rotation direction about the preset axis Ax3 is 0-135°. For example, the rotation angle range of the stick body assembly 70 in the rotation direction is 30°, 60°, 90° or 120°.

[0171] In this way, the microphone assembly 80 can be moved in the area where the sound is effectively captured, so as to improve the voice collection effect of the microphone assembly 80, and facilitate the adjustment of the position of the microphone assembly 80, and reduce the probability of adjusting the microphone assembly 80 to an unreasonable position. If the rotation angle range is larger, the probability of adjusting the microphone assembly 80 to an unreasonable position will increase, which is not conducive to the work of the microphone assembly 80 and reduces the user experience effect.

[0172] Optionally, as shown in Figure 16 and Figure 19As shown in FIG. 9, the stick assembly 70 is provided with a limiting slot 940 extending along the rotation direction of the stick assembly 70, and the speaker assembly 3 is provided with a limiting protrusion 3301 which is slidably inserted into the limiting slot 940. The two ends of the limiting slot 940 are used to limit the sliding of the limiting protrusion 3301, thereby limiting the relative rotation of the stick assembly 70 and the speaker assembly 3.

[0173] As shown in FIG. 9, the stick assembly 70 is provided with a limiting slot 940 extending along the rotation direction of the stick assembly 70, and the speaker assembly 3 is provided with a limiting protrusion 3301 which is slidably inserted into the limiting slot 940. The two ends of the limiting slot 940 are used to limit the sliding of the limiting protrusion 3301, thereby limiting the relative rotation of the stick assembly 70 and the speaker assembly 3. Figure 4 、 Figure 16 and Figure 17 As shown in FIG. 9, the stick assembly 70 is provided with a limiting slot 940 extending along the rotation direction of the stick assembly 70, and the speaker assembly 3 is provided with a limiting protrusion 3301 which is slidably inserted into the limiting slot 940. The two ends of the limiting slot 940 are used to limit the sliding of the limiting protrusion 3301, thereby limiting the relative rotation of the stick assembly 70 and the speaker assembly 3.

[0174] The extension direction of the stick assembly 70 can be close to or consistent with the extension direction of the elastic sheet 71. By setting the elastic sheet 71 to gradually bend towards the face in the direction from the end close to the speaker assembly 3 to the end away from the speaker assembly 3, the microphone assembly 80 can be close to the sound pickup area, so as to capture the sound of the mouth of the person and improve the sound pickup effect, while reducing the interference probability of the stick assembly 70 with the face and improving the wearing comfort.

[0175] As shown in FIG. 9, the stick assembly 70 is provided with a limiting slot 940 extending along the rotation direction of the stick assembly 70, and the speaker assembly 3 is provided with a limiting protrusion 3301 which is slidably inserted into the limiting slot 940. The two ends of the limiting slot 940 are used to limit the sliding of the limiting protrusion 3301, thereby limiting the relative rotation of the stick assembly 70 and the speaker assembly 3. Figure 17 and Figure 20 As shown in FIG. 9, the stick assembly 70 is provided with a limiting slot 940 extending along the rotation direction of the stick assembly 70, and the speaker assembly 3 is provided with a limiting protrusion 3301 which is slidably inserted into the limiting slot 940. The two ends of the limiting slot 940 are used to limit the sliding of the limiting protrusion 3301, thereby limiting the relative rotation of the stick assembly 70 and the speaker assembly 3.

[0176] In this way, the elastic sheet 71 is easy to deform in the thickness direction Hm and not easy to deform in the width direction Wm, which is convenient for adjusting the position of the microphone assembly 80. If the ratio is too large, the elastic sheet 71 is not easy to deform in the thickness direction Hm, which increases the difficulty of the user to adjust the position of the microphone assembly 80. If the ratio is too small, the mechanical strength of the elastic sheet 71 is poor, the supporting and shaping effect is insufficient, and it will adversely affect the structural stability of the stick assembly 70.

[0177] Optionally, the elastic sheet 71 is a titanium sheet. In this way, the elastic sheet 71 has good mechanical strength and deformation ability, which is beneficial to improve the service life of the elastic sheet 71.

[0178] Optionally, the size HD1 of the elastic sheet 71 in the thickness direction Hm ranges from 0.3 mm to 0.5 mm. Further, the size HD1 of the elastic sheet 71 in the thickness direction Hm ranges from 0.36 mm to 0.44 mm.

[0179] In this way, the elastic sheet 71 is easy to deform in the thickness direction Hm, facilitating adjustment of the position of the microphone assembly 80, and the elastic sheet 71 has sufficient mechanical strength, thereby having good support and shaping functions. If the size is too large, the elastic sheet 71 is not easy to deform in the thickness direction Hm, increasing the difficulty of adjustment of the position of the microphone assembly 80 by the user. If the size is too small, the mechanical strength of the elastic sheet 71 is poor, and the support and shaping functions are insufficient.

[0180] Optionally, the size WD1 of the elastic sheet 71 in the width direction Wm ranges from 1.8 mm to 2.2 mm. Further, the size WD1 of the elastic sheet 71 in the width direction Wm ranges from 1.96 mm to 2.04 mm.

[0181] In this way, the elastic sheet 71 is not easy to deform in the width direction Wm, facilitating directional adjustment of the position of the microphone assembly 80 by the user, and the elastic sheet 71 has sufficient mechanical strength, thereby having good support and shaping functions. If the size is too large, the elastic sheet 71 occupies a large space, which is not conducive to miniaturization of the stick assembly 70. If the size is too small, the mechanical strength of the elastic sheet 71 is poor, and the support and shaping functions are insufficient, and the directional deformation of the elastic sheet 71 is affected.

[0182] Optionally, as shown in Figs. Figure 4 and Figure 16 The microphone assembly 80 is fixedly connected to the end of the stick assembly 70 away from the preset axis Ax3. When the microphone assembly 80 is working, the end of the stick assembly 70 close to the preset axis Ax3 is close to the ear of the user, and the end of the stick assembly 70 away from the preset axis Ax3 is close to the mouth of the user, so that the earphone 1 can extend from the ear of the user to the mouth of the user.

[0183] The microphone assembly 80 includes a containing shell 81, a microphone 82, a microphone circuit board 83, and a button module 84. The containing shell 81 is provided with a containing cavity 810 and a microphone hole 811 communicating with the containing cavity 810, the microphone 82 and the microphone circuit board 83 are arranged in the containing cavity 810, and the microphone 82 is fixed on the microphone circuit board 83 and arranged opposite to the microphone hole 811. The containing shell 81 includes two first shell walls 8101 arranged opposite to each other in the width direction Wm, two second shell walls 8102 arranged opposite to each other in the thickness direction Hm, and an end wall 8103 away from the end of the preset axis Ax3. The microphone hole 811 is arranged on the second shell wall 8102 or the end wall 8103, and the button module 84 is arranged on the first shell wall 8101. The button module 84 is used to control the opening or closing of the microphone 82.

[0184] External sound can be transmitted to the microphone 82 through the microphone hole 811, the microphone 82 can convert the captured sound into an electrical signal, and a circuit cooperating with the working of the microphone 82 can be arranged on the microphone circuit board 83.

[0185] By setting the microphone hole 811 on the second shell wall 8102 or the end wall 8103, and setting the key module 84 on the first shell wall 8101, the key module 84 and the microphone hole 811 are respectively arranged on different surfaces of the accommodating shell 81, and there is a large gap between the key module 84 and the microphone hole 811, which can reduce the situation that the microphone hole 811 is blocked when the user presses the key module 84, and can also reduce the adverse effect of the generated key mechanical noise on the sound collection of the microphone 82, improve the sound capture effect of the microphone assembly 80, and facilitate the user to press the key module 84.

[0186] Optionally, the microphone circuit board 83 can be a flexible circuit board (FPC).

[0187] Optionally, as shown in Figure 17 , Figure 18 and Figure 21 , the first shell wall 8101 is provided with a key hole 8104, the key module 84 includes a key 841 and a adapter circuit board 842, and the adapter circuit board 842 is electrically connected with the microphone circuit board 83. The adapter circuit board 842 is arranged in the accommodating cavity 810, the key 841 is arranged in the key hole 8104 and blocks the key hole 8104, the adapter circuit board 842 is provided with a switch 8421, and the key 841 abuts against the switch 8421 to control the opening or closing of the microphone 82 by pressing the switch 8421.

[0188] The adapter circuit board 842 and the key 841 can effectively realize the function of controlling the opening or closing of the microphone 82, so that the switch 8421 can not be arranged on the microphone circuit board 83, which can adapt to the structure of the earphone 1. Compared with combining the circuit on the microphone circuit board 83 and the circuit on the adapter circuit board 842 into one circuit board, separately arranging the microphone circuit board 83 and the adapter circuit board 842 can reduce the crosstalk between the circuit on the microphone circuit board 83 and the circuit on the adapter circuit board 842. By setting the key 841 to block the key hole 8104, it is beneficial to reduce the entry of external water vapor and dust into the accommodating cavity 810, and improve the sealing effect.

[0189] Optionally, the adapter circuit board 842 is a flexible circuit board (FPC).

[0190] Optionally, as shown in Figure 17 , Figure 18 and Figure 21As shown, the key 841 includes an elastic body 8412 and a key body 8411 abutting against the elastic body 8412, the elastic body 8412 is located in the accommodating cavity 810 and blocks the key hole 8104 from the accommodating cavity 810, and the key body 8411 is located on the side of the elastic body 8412 away from the accommodating cavity 810 and exposed through the key hole 8104. The key module 84 includes a fixing plate 843 supported on the side of the adapter circuit board 842 away from the elastic body 8412 to clamp the adapter circuit board 842 between the fixing plate 843 and the elastic body 8412, and the fixing plate 843 is fixedly arranged in the accommodating cavity 810.

[0191] The elastic body 8412 can be elastically deformed, and the key body 8411 can apply a force to the adapter circuit board 842 through the elastic body 8412 when pressed to trigger the switch 8421. By arranging the fixing plate 843, the installation of the adapter circuit board 842 is facilitated, and the structure of the key module 84 is more stable after the adapter circuit board 842 is installed.

[0192] In some embodiments, the elastic body 8412 is tightly abutted to the accommodating shell 81 under pressure to block the key hole 8104. In other embodiments, the elastic body 8412 is sealingly connected with the accommodating shell 81 by molding such as injection molding or compression molding.

[0193] Optionally, as shown in Figure 17 , Figure 18 and Figure 22 , the number of microphones 82 is at least two, including a first microphone 82a and a second microphone 82b, and the number of microphone holes 811 is at least two, including a first microphone hole 811a and a second microphone hole 811b, the first microphone hole 811a is located on the end wall 8103, and the second microphone hole 811b is located on the second shell wall 8102. The first microphone 82a and the second microphone 82b are fixedly arranged on the microphone circuit board 83 and correspond to the first microphone hole 811a and the second microphone hole 811b respectively. The second microphone hole 811b is closer to one end of the accommodating shell 81 close to the preset axis Ax3 between the two ends of the accommodating shell 81.

[0194] Specifically, the first microphone hole 811a and the second microphone hole 811b have different orientations to the outside, and at the same time, the second microphone hole 811b is farther away from the mouth and captures stronger environmental noise, and the first microphone hole 811a is closer to the mouth and captures stronger user voice, so that the first microphone hole 811a and the second microphone hole 811b can achieve the effect of eliminating environmental noise. Further, the second microphone hole 811b is located on the second shell wall 8102 away from the face to enhance the capture effect of environmental noise.

[0195] Further, the arrangement of the at least two microphones 82 can improve the sound pickup effect, and the at least two microphones 82 are far away from each other, which can facilitate sound pickup in a larger range and reduce mutual interference between the two microphones 82. In addition, the two microphones 82 are far away from each other, and the two microphones 82 are not easily blocked by the user at the same time when the key module 84 is pressed.

[0196] Optionally, as shown in Figure 17 、 Figure 18 and Figure 22 , the accommodating shell 81 comprises a shell body 812 and a cover body 813. The shell body 812 has a part of the second shell wall 8102 to enclose an opening of the accommodating cavity 810. The cover body 813 covers the opening to form another part of the corresponding second shell wall 8102. In this way, the assembly of the parts inside the accommodating shell 81 is facilitated.

[0197] The microphone circuit board 83 comprises a first fixed plate part 831 and a second fixed plate part 832. The first fixed plate part 831 is arranged opposite to the end wall 8103 to fix the first microphone 82a. The second fixed plate part 832 is arranged opposite to the corresponding second shell wall 8102 to fix the second microphone 82b. In this way, the installation of the microphone 82 is facilitated, the electrical connection between the microphone 82 and the microphone circuit board 83 is more stable after installation, the position of the microphone 82 is kept stable, the structure of the microphone circuit board 83 is flexible, and the stick assembly 70 is miniaturized.

[0198] The cover body 813 comprises a cover plate 8131, a first support protrusion 8132, and a second support protrusion 8133. The first support protrusion 8132 and the second support protrusion 8133 are protrudingly arranged on the side of the cover plate 8131 facing the accommodating cavity 810. The first support protrusion 8132 is arranged opposite to the end wall 8103 to support the first fixed plate part 831 and / or the first microphone 82a towards the end wall 8103. The second support protrusion 8133 extends towards the corresponding second shell wall 8102 to support the second fixed plate part 832 and / or the second microphone 82b.

[0199] Specifically, the first support protrusion 8132 and the second support protrusion 8133 extend in the same direction, the side surface of the first support protrusion 8132 supports the first fixed plate part 831, and the end surface of the second support protrusion 8133 along the extending direction of the second support protrusion 8133 supports the second fixed plate part 832. In this way, the installation of the microphone 82 and the microphone circuit board 83 is facilitated, and the structure inside the accommodating shell 81 is more stable after installation of the microphone 82 and the microphone circuit board 83. Further, the number of the second support protrusions 8133 is two or more to improve the limiting effect on the second fixed plate part 832.

[0200] Optionally, as shown in Figures 16 to 18 ,Figure 22 As shown, the stick body assembly 70 includes a first connector block 73 fixedly arranged at one end of the elastic sheet 71 away from the preset axis Ax3, and the elastic covering body 72 further extends to cover a portion of the outer periphery of the first connector block 73. The first connector block 73 is provided with a first lead hole 730. The accommodating shell 81 is provided with a first connector hole 8105 at one end close to the preset axis Ax3, and the first connector block 73 is inserted into the first connector hole 8105. The microphone circuit board 83 is connected with the lead wire 211, which penetrates into the elastic covering body 72 from the accommodating cavity 810 through the first lead hole 730 to lead to the speaker assembly 3.

[0201] In this way, the assembly and connection of the stick body assembly 70 and the microphone assembly 80 are facilitated.

[0202] The first connector hole 8105 can be in communication with the accommodating cavity 810. By arranging the first lead hole 730 on the first connector block 73, the lead wire 211 can be fixed and protected, and the lead wire 211 can be easily penetrated into the elastic covering body 72 from the accommodating cavity 810. By penetrating the lead wire 211 into the elastic covering body 72, the elastic covering body 72 can protect the lead wire 211, and the lead wire 211 can move relative to the elastic covering body 72 and the first connector block 73, so that the lead wire 211 can be less pulled when the elastic sheet 71 is deformed, and the service life of the lead wire 211 can be improved.

[0203] The portion of the outer periphery of the first connector block 73 not covered by the elastic covering body 72 can be inserted into the first connector hole 8105. Further, the outer periphery of the elastic covering body 72 is flush with the outer periphery of the accommodating shell 81 at the connection to improve the appearance.

[0204] Optionally, as shown in Figures 16 to 18 , Figure 23 The stick microphone assembly 7 includes a rotating shaft mechanism 91. The stick body assembly 70 includes a second connector block 74 fixedly arranged at one end of the elastic sheet 71 close to the preset axis Ax3, and the elastic covering body 72 further extends to cover a portion of the outer periphery of the second connector block 74. The rotating shaft mechanism 91 is rotatably arranged around the preset axis Ax3 of the speaker assembly 3. The rotating shaft mechanism 91 is provided with a second connector hole 910, and the second connector block 74 is inserted into the second connector hole 910. The second connector block 74 is provided with a second lead hole 741, and the lead wire 211 of the stick microphone assembly 7 penetrates into the rotating shaft mechanism 91 from the elastic covering body 72 through the second lead hole 741 and enters the speaker assembly 3 through the rotating shaft mechanism 91.

[0205] In this way, the assembly and connection of the stick body assembly 70 and the rotating shaft mechanism 91 are facilitated.

[0206] By rotatably mounting the rotating shaft mechanism 91 around the preset axis Ax3 on the speaker assembly 3, the stick assembly 70 and the microphone assembly 80 can rotate around the preset axis Ax3.

[0207] The second connector hole 910 can communicate with the inside of the rotating shaft mechanism 91. By providing a second lead hole 741 on the second connector block 74, the wire 211 can be fixed and protected, facilitating the insertion of the wire 211 from inside the elastic cover 72 into the rotating shaft mechanism 91. The wire 211 can move relative to the elastic cover 72 and the second connector block 74, thereby reducing the pulling on the wire 211 when the elastic sheet 71 deforms, which helps to improve the life of the wire 211.

[0208] The portion of the outer periphery of the second connector 74 not covered by the elastic cover 72 can be inserted into the second connector hole 910. Furthermore, the outer periphery of the elastic cover 72 is flush with the outer periphery of the rotating shaft mechanism 91 at the connection point to improve the aesthetic appearance.

[0209] The following is an exemplary structure of the microphone assembly 7, etc., in an embodiment of the earphone of this application.

[0210] like Figure 4 , Figure 16 and Figure 18 As shown, in some embodiments, the earphone 1 may include a wearing component 2, a speaker component 3, and a microphone component 7. The wearing component 2 is connected to the speaker component 3, and the microphone component 7 is rotatably mounted on the speaker component 3 about a preset axis Ax3. The speaker component 3 includes a housing component 30 and a speaker. The housing component 30 is provided with an accommodating space 300 and a pivot hole 330 communicating with the accommodating space 300, and the speaker is disposed within the accommodating space 300. The microphone component 7 includes a button module 92, a microphone body component 70, and a pivot mechanism 91. The pivot mechanism 91 passes through the pivot hole 330 and is rotatable relative to the housing component 30 about a preset axis Ax3. The pivot mechanism 91 includes a pivot base 912 and a pivot bracket 913, which are assembled along the preset axis Ax3. A portion of the pivot base 912 is located outside the housing component 30 and is connected to the microphone body component 70. The button module 92 includes a button circuit board 921 and a button 922. The button circuit board 921 is clamped between the pivot base 912 and the pivot bracket 913. A switch 9210 is provided on the button circuit board 921, and a button 922 is provided on the pivot base 912 for pressing the switch 9210.

[0211] The loudspeaker may include at least one of a bone conduction loudspeaker 40 and an air conduction loudspeaker 50.

[0212] The speaker assembly 3 transmits sound to the user's ear. The wearing component 2 hangs the speaker assembly 3 near the user's ear and applies force to the speaker assembly 3 to make it fit against the user's face near the ear. The microphone assembly 7 captures the sound emitted by the user's mouth, thereby collecting the user's voice.

[0213] By incorporating a pivot mechanism 91, the assembly and connection of the microphone assembly 70 and the speaker assembly 3 are facilitated. By configuring the pivot mechanism 91 to rotate relative to the housing assembly 30 around a preset axis Ax3, the microphone assembly 7 can rotate around the preset axis Ax3, thus providing a greater range of motion to meet different sound capture needs. Furthermore, the microphone assembly 7 can switch between a storage position and a working position by rotating around the preset axis Ax3.

[0214] The button module 92 can be used to trigger the operation of the microphone component 7. For example, a user can answer a phone call by pressing the button module 92, and the microphone component 7 will capture the user's voice when the user speaks.

[0215] Specifically, button 922 may be located on the portion of the hinge base 912 outside the housing assembly 30 and exposed to the outside for easy pressing. Part of the hinge bracket 913 may be located inside the housing assembly 30 to prevent the hinge bracket 913 from detaching from the housing assembly 30.

[0216] By setting the key circuit board 921 between the pivot base 912 and the pivot bracket 913, the key circuit board 921 can be fixed to the pivot mechanism 91. When the pivot mechanism 91 rotates, the key circuit board 921 rotates synchronously with the pivot mechanism 91. Moreover, the key circuit board 921 can be assembled and fixed during the assembly process of the pivot base 912 and the pivot bracket 913, which facilitates the installation of the key circuit board 921 and improves assembly efficiency.

[0217] Optionally, the pivot base 912 is configured to be mounted on the housing assembly 30 from the outside of the housing assembly 30, and partially located within the pivot hole 330. This configuration facilitates the mounting of the pivot base 912 on the housing assembly 30, and also facilitates the assembly and connection of the pivot base 912 with the rod assembly 70.

[0218] The hinge bracket 913 is configured to assemble with the hinge base 912 within the accommodating space 300, so that the hinge base 912 remains within the hinge hole 330. This configuration facilitates at least partially confining the hinge bracket 913 within the housing assembly 30, thereby enabling the assembly of the hinge base 912 onto the housing assembly 30 and preventing the hinge base 912 from detaching from the housing assembly 30. During the assembly of the hinge base 912 and the hinge bracket 913, the button circuit board 921 can be assembled simultaneously to improve assembly efficiency.

[0219] Optionally, such as Figure 16 and Figure 19 As shown, a limiting groove 940 is provided on the pivot base 912, extending along the rotation direction of the pivot base 912. A limiting protrusion 3301 is provided in the pivot hole 330, and the limiting protrusion 3301 is slidably inserted into the limiting groove 940. The limiting protrusion 3301 can slide along the extension direction of the limiting groove 940 to allow the pivot base 912 and the speaker assembly 3 to rotate relative to each other. The two ends of the limiting groove 940 are used to restrict the sliding of the limiting protrusion 3301, thereby restricting the relative rotation of the pivot base 912 and the speaker assembly 3.

[0220] Optionally, such as Figure 18 , Figures 23 to 25 As shown, the pivot base 912 has a mounting hole 9120 extending through along a preset axis Ax3, and a supporting flange 9121 protrudes from the inner wall of the mounting hole 9120. One end of the pivot bracket 913 extends into the mounting hole 9120. The button circuit board 921 is supported between the supporting flange 9121 and one end of the pivot bracket 913. The switch 9210 is located on the side of the button circuit board 921 facing away from the receiving space 300, and the button 922 is received in the mounting hole 9120 and abuts against the switch 9210.

[0221] The mounting hole 9120 facilitates contact and abutment between the button circuit board 921 and the button 922. By housing the button 922 within the mounting hole 9120, the microphone assembly 7 achieves a compact structure. Simultaneously, the mounting hole 9120 limits the position of the button 922, thus facilitating its assembly. The support flange 9121 increases the contact area between the pivot base 912 and the button circuit board 921, improving the support and fixation effect of the pivot base 912 on the button circuit board 921, thereby enhancing structural stability.

[0222] Optionally, such as Figure 18 , Figures 23 to 25 As shown, button 922 includes button cap 9221 and elastic abutment 9222. The elastic abutment 9222 is disposed within mounting hole 9120 and fixedly supported on the side of support flange 9121 facing away from button circuit board 921. The elastic abutment 9222 abuts against switch 9210. Button cap 9221 is disposed on the side of elastic abutment 9222 facing away from switch 9210 and exposed through mounting hole 9120. Support flange 9121 is arranged in a ring around a preset axis Ax3. Elastic abutment 9222 is integrally formed on support flange 9121 along its circumferential direction to seal mounting hole 9120 at support flange 9121.

[0223] The exposed button cap 9221 facilitates user pressing. The elastic abutment 9222 is flexible, allowing the button cap 9221 to transmit the pressing action to the button circuit board 921, triggering the switch 9210. By providing a support flange 9121 to support the elastic abutment 9222, the contact area between the pivot base 912 and the elastic abutment 9222 is increased, facilitating the installation of the button cap 9221 and the elastic abutment 9222, and also making it easier for the elastic abutment 9222 to seal the mounting hole 9120.

[0224] By integrally molding the elastic abutment 9222 onto the support flange 9121 in the circumferential direction, the elastic abutment 9222 provides a good seal to the mounting hole 9120, thereby preventing water and dust from entering the interior of the housing assembly 30 and simplifying the structure. Furthermore, the elastic abutment 9222 can be integrally molded onto the support flange 9121 in the circumferential direction using a secondary injection molding or compression molding method.

[0225] Optionally, such as Figure 18 , Figures 23 to 25 As shown, the elastic abutment member 9222 includes an abutment post 9223, an annular sealing portion 9224 surrounding and connected to the abutment post 9223, and a cylindrical sealing portion 9225 connected to the side of the annular sealing portion 9224 facing the button circuit board 921 and surrounding the abutment post 9223. The annular sealing portion 9224 is supported on and sealed to the support flange 9121, and the cylindrical sealing portion 9225 extends to the inner annular surface of the support flange 9121 and is sealed to the inner annular surface of the support flange 9121. The two ends of the abutment post 9223 abut against the button cap 9221 and the switch 9210, respectively.

[0226] By configuring the annular sealing portion 9224 to support the supporting flange 9121, the installation of the elastic abutment member 9222 is facilitated. By configuring the cylindrical sealing portion 9225 to extend to the inner annular surface of the supporting flange 9121, the contact area between the shaft base 912 and the elastic abutment member 9222 is increased, and the shaft base 912 and the elastic abutment member 9222 are sealed and abutted in different directions, which improves the sealing effect of the elastic member on the assembly hole 9120. By providing the abutment post 9223, the pressing action from the button cap 9221 can be concentrated on the abutment post 9223, and the pressing action can be transmitted to the switch 9210 more concentratedly, which is beneficial to the sensitive response of the switch 9210 to the user's pressing action.

[0227] Optionally, such as Figure 18 , Figures 23 to 25As shown, the hinge bracket 913 is provided with a wiring hole 9130 extending through along a preset axis Ax3, and one side of the button circuit board 921 faces the wiring hole 9130. The wiring hole 9130 and the mounting hole 9120 are connected to each other. The speaker assembly 3 includes a control circuit board 62 to which a wire harness 211a is connected. The control circuit board 62 is disposed within the accommodating space 300 and is disposed opposite to the hinge hole 330. The wire harness 211a is connected to the button circuit board 921 along the preset axis Ax3 via the wiring hole 9130.

[0228] By providing wiring holes 9130, the wiring harness 211a can be easily arranged, enabling electrical connection between the microphone assembly 7 and the control circuit board 62. The wiring holes 9130 and mounting holes 9120 can communicate with each other along the preset axis Ax3, allowing the wiring harness 211a to extend along the preset axis Ax3, with the preset axis Ax3 approaching or passing through the wiring harness 211a. When the microphone assembly 7 rotates, the wiring harness 211a rotates approximately on the preset axis Ax3 or rotates with a small radius, thereby reducing the pulling and torsional effects of the microphone assembly 7 on the wiring harness 211a and improving its lifespan.

[0229] Optionally, such as Figure 18 , Figures 23 to 25 As shown, the control circuit board 62 is provided with a through hole 620 extending along a preset axis Ax3. The through hole 620 is positioned opposite to the wiring hole 9130. The wire harness 211a extends from the side of the control circuit board 62 away from the pivot hole 330 through the through hole 620 along the preset axis Ax3 into the wiring hole 9130. The speaker assembly 3 includes an elastic ring 621, which is fixed inside the through hole 620. The wire harness 211a passes through the elastic ring 621. For example, the elastic ring 621 can be a rubber ring.

[0230] The wire pass hole 620 allows the wire bundle 211a to pass through, thereby limiting the wire bundle 211a. By setting the wire pass hole 620 opposite to the wire routing hole 9130, it is beneficial for the wire bundle 211a to extend along the preset axis Ax3, thereby improving the stability of the connection structure between the wire bundle 211a and the control circuit board 62.

[0231] The elastic ring 621 is elastic. When the wire harness 211a moves relative to the elastic ring 621, the elastic ring 621 can undergo elastic deformation. While limiting the wire harness 211a, it can reduce the movement resistance of the wire harness 211a and also prevent the edge of the wire hole 620 from scratching the wire harness 211a.

[0232] Optionally, such as Figure 18 , Figures 23 to 25As shown, the elastic ring 621 has an annular groove 6210 along its circumference. The part of the control circuit board 62 located outside the wire hole 620 is embedded in the annular groove 6210, so that the elastic ring 621 is snapped onto the control circuit board 62.

[0233] By setting the portion of the control circuit board 62 located around the wire hole 620 to be embedded in the annular groove 6210, the connection structure between the elastic ring 621 and the control circuit board 62 can be simplified, making it easier to assemble and connect the elastic ring 621 and the control circuit board 62, and improving the connection stability between the elastic ring 621 and the control circuit board 62.

[0234] Optionally, such as Figure 18 , Figures 23 to 25 As shown, the pivot base 912 includes an end portion 9122 extending into the pivot hole 330 and / or the receiving space 300, and the end portion 9122 is provided with at least two slots 9123 spaced apart circumferentially. The at least two slots 9123 divide the end portion 9122 into at least two resilient arms 9124 spaced apart from each other circumferentially. The pivot bracket 913 includes a shaft body 9132 and at least two locking blocks 9133 protruding from the outer periphery of the shaft body 9132. The shaft body 9132 is inserted into the mounting hole 9120 and located between the at least two resilient arms 9124. The at least two locking blocks 9133 are correspondingly embedded in the at least two slots 9123 to support adjacent resilient arms 9124 in the corresponding slots 9123.

[0235] The elastic arm 9124 is elastic and can undergo elastic deformation. By providing the slot 9123, the elastic arm 9124 can be easily deformed during assembly, making the shaft base 912 easier to assemble. The shaft body 9132 and at least two locking blocks 9133 can support and limit the at least two elastic arms 9124, restricting deformation of the elastic arms 9124 after assembly, thereby improving structural stability. By embedding at least two locking blocks 9133 one-to-one into at least two slots 9123, the shaft base 912 and the shaft support 913 can remain relatively fixed, allowing the shaft base 912 and the shaft support 913 to rotate synchronously around a preset axis Ax3.

[0236] Optionally, such as Figure 18 , Figures 23 to 25 As shown, at least two locking blocks 9133 have first stop flanges 913a protruding from their outer surfaces. At least two elastic arms 9124 have second stop flanges 912a protruding from their outer surfaces at the ends away from the button module 92. The first stop flanges 913a and the second stop flanges 912a are arranged complementaryly along the circumference of the shaft 9132 and abut against the side wall of the housing assembly 30 facing the accommodating space 300 around the pivot hole 330.

[0237] Through the elastic deformation of the elastic arm 9124, during the assembly process, the second stop edge 912a can pass through the pivot hole 330 to reach the periphery of the pivot hole 330 and abut against the side wall of the housing assembly 30 facing the receiving space 300, so that the pivot base 912 can be engaged with the housing assembly 30, facilitating the assembly of the pivot base 912. The shaft body 9132 and at least two locking blocks 9133 can support and limit at least two elastic arms 9124, preventing the elastic arms 9124 from deforming and detaching from the housing assembly 30 after assembly, thereby improving structural stability.

[0238] By providing the first stop flange 913a, the housing assembly 30 can support the shaft bracket 913, thereby facilitating the installation of the shaft bracket 913. By providing complementary first stop flange 913a and second stop flange 912a along the circumference of the shaft 9132, the shaft mechanism 91 can be made compact and space-saving.

[0239] Optionally, such as Figure 18 , Figures 23 to 25 As shown, a third stop flange 912b protrudes from the outer periphery of the pivot base 912 and is in the shape of an annular ring. The first stop flange 913a and the third stop flange 912b are spaced apart along a preset axis Ax3. The third stop flange 912b abuts against the other side wall of the housing assembly 30 opposite to the receiving space 300.

[0240] In this way, the second stop flange 912a and the third stop flange 912b can be spaced apart along the preset axis Ax3. During the assembly process, the third stop flange 912b can play a positioning role, restricting the rotation of the shaft base 912 towards the receiving space 300 after it is inserted into the shaft hole 330, which facilitates the assembly of the shaft base 912 and improves the structural stability after assembly.

[0241] Optionally, such as Figure 18 , Figures 12 to 24 As shown, the rotating shaft mechanism 91 includes a sealing ring 914. An annular groove 915 is circumferentially provided on the outer periphery of the rotating shaft base 912. The annular groove 915 is spaced apart from at least two retaining grooves 9123 along a preset axis Ax3. The sealing ring 914 is fitted onto the rotating shaft base 912 and abuts against the wall of the rotating shaft hole 330.

[0242] The annular groove 915 can be used to limit the sliding of the sealing ring 914 after installation. By fitting the sealing ring 914 onto the shaft base 912 and abutting against the wall of the shaft base 912 and the shaft hole 330, a seal can be formed between the shaft base 912 and the wall of the shaft hole 330, preventing water and dust from entering the interior of the housing assembly 30. By arranging the annular groove 915 along a predetermined axis Ax3 and spaced apart from at least two slots 9123, the interference of the formation of the slots 9123 on the sealing effect of the annular groove 915 can be reduced.

[0243] Optionally, such as Figure 18 , Figures 23 to 25 As shown, the pivot base 912 is provided with a connector hole, and the rod assembly 70 is provided with a connector portion, which is inserted into the connector hole. The bottom wall of the connector hole is provided with a through hole 912c that communicates with the mounting hole 9120. The pivot bracket 913, which supports the button circuit board 921, has a first notch 9134 at one end, and the button circuit board 921 has a second notch 9211 that communicates with the first notch 9134. The wire harness 211a includes a wire 211 for leading to the rod assembly 70. The wire 211 passes through the first notch 9134 and the second notch 9211 from the side of the button circuit board 921 away from the switch 9210, and is led into the connector hole, and then to the rod assembly 70.

[0244] The connector can be the second connector block 74 mentioned above, and the connector hole can be the second connector hole 910 mentioned above. By inserting the connector into the connector hole, the assembly and connection of the rotating shaft base 912 and the rod assembly 70 can be facilitated. The operating state of the rod assembly 70 can be controlled by the control circuit board 62 or the button circuit board 921 through the wire 211. By providing a through hole 912c on the bottom wall of the connector hole, the wire 211 can extend from the assembly hole 9120 to the through hole 912c and then through the through hole 912c to the connector hole, thereby reducing the lead-out path length of the wire 211. By providing a first notch 9134 and a second notch 9211 to avoid the wire 211, the structure of the rotating shaft mechanism 91 can be simplified, the wire 211 can be arranged more easily, and the pulling on the wire 211 can be reduced.

[0245] Optionally, such as Figure 18 , Figures 23 to 25 As shown, the speaker assembly 3 includes an annular light guide 93, which surrounds the pivot hole 330 and a portion of the annular light guide 93 extends into the accommodating space 300. The speaker assembly 3 includes a control circuit board 62 disposed within the accommodating space 300. A light-emitting element 622 is disposed on the control circuit board 62, which emits light. The light guide is used to conduct the light emitted by the light-emitting element 622 to the outside of the housing assembly 30.

[0246] The light can serve as a prompt to the user. By arranging the annular light guide 93 around the pivot hole 330, the light emission range is larger, the prompt is more eye-catching, and it is easier for the user or others to see the light. Moreover, the annular light guide 93 can be placed closer to the button module 92, which can reduce the space occupied by the button module 92 and the annular light guide 93, making the structure more compact. At the same time, it is easier to connect the button circuit board 921 and the light-emitting element 622 to the control circuit board 62 in a compact structure, reducing the line length.

[0247] Furthermore, the annular light guide 93 surrounding the pivot hole 330 allows the light-emitting element 622 and the wire 211 connecting the microphone assembly 7 to be arranged compactly on the control circuit board 62.

[0248] Optionally, such as Figure 18 , Figures 23 to 25 As shown, the annular light guide 93 includes an annular light guide body 931 and a light guide post 932 connected to the annular light guide body 931. The housing assembly 30 is provided with an annular groove 340 surrounding the pivot hole 330 and spaced apart from the pivot hole 330 on the side opposite to the accommodating space 300. The housing assembly 30 is provided with a light guide hole 341 on the bottom wall of the annular groove 340, which connects the annular groove 340 and the accommodating space 300. The annular light guide body 931 is embedded in the annular groove 340, and the light guide post 932 passes through the light guide hole 341. The light-emitting element 622 is used to emit light at least toward the light guide post 932.

[0249] The annular groove 340 facilitates the assembly and fixation of the annular light guide 93 on the housing assembly 30. The light guide post 932 is used to propagate light; by passing the light guide post 932 through the light guide hole 341, light can propagate from the inside of the housing assembly 30 to the outside. The light guide post 932 also limits the position of the annular light guide 93 within the housing assembly 30, promoting a stable connection between the annular light guide 93 and the housing assembly 30.

[0250] Furthermore, the light guide post 932 and the light guide hole 341 can be tightly fitted together. By passing the light guide post 932 through the light guide hole 341, the connection between the annular light guide 93 and the housing assembly 30 can be realized.

[0251] Optionally, the number of light guide posts 932 can be set to multiple. The cross-section of the light guide post 932 perpendicular to the preset axis Ax3 can be cylindrical or arc-shaped along the circumference of the rotating shaft hole 330.

[0252] Optionally, such as Figure 18 , Figures 23 to 25As shown, the rotating shaft base 912 includes a main shaft seat 9125 and a connecting portion 9126 protruding from the outer periphery of the main shaft seat 9125. The connecting portion 9126 has a insertion hole, and the roller assembly 70 has an insertion portion that is inserted into the insertion hole. The main shaft seat 9125 can be partially inserted into the rotating shaft hole 330. By inserting the insertion portion into the insertion hole, it is convenient to assemble and connect the rotating shaft base 912 and the roller assembly 70.

[0253] The insertion part can be the second insertion block 74 mentioned above, and the insertion hole can be the second insertion hole 910 mentioned above. The connecting part 9126 forms a stop for the annular light guide 931 in the direction of the preset axis Ax3. In this way, the annular light guide 931 can be prevented from disengaging from the annular groove 340 along the preset axis Ax3, which helps to improve the structural stability of the annular light guide 93.

[0254] Optionally, such as ​ , ​ As shown, the stick-microphone assembly 7 includes a microphone assembly 80. The microphone assembly 80 is fixedly connected to the end of the stick assembly 70 away from the speaker assembly 3. The microphone assembly 80 includes a housing 81 and a microphone 82. The microphone 82 is electrically connected to a control circuit board 62 via a wire 211. The control circuit board 62 is used to control the light-emitting element 622 to emit light when the microphone 82 is in the sound-picking state.

[0255] The microphone assembly 80 can capture sounds emitted from a person's mouth, thereby collecting the user's voice. The stick assembly 70 can be connected between the microphone assembly 80 and the speaker assembly 3. By controlling the movement of the stick assembly 70, the microphone assembly 80 can be controlled to be in different positions and postures. For example, when the microphone assembly 80 is no longer in use, the microphone assembly 80 can be moved away from the sound pickup area and closer to the wearing assembly 2 by controlling the movement of the stick assembly 70, so that the microphone assembly 80 is in a stored position.

[0256] Once the microphone 82 is turned on, it is in the sound pickup state and can work. By using the control circuit board 62 to control the light-emitting element 622 to light up when the microphone 82 is in the sound pickup state, it can be confirmed by external parties whether the microphone 82 is turned on.

[0257] Furthermore, compared to the case where the microphone 82 does not capture the user's voice, the intensity or color of the light emitted by the light-emitting element 622 may change after the microphone 82 captures the user's voice. In some embodiments, the light-emitting element 622 is configured such that the intensity or color of the light emitted can change according to the volume of the user's voice. In some embodiments, the light-emitting element 622 transmits information to the outside world by adjusting the flashing frequency.

[0258] In some embodiments, a user can make a phone call through the headset 1. During the call, the light-emitting element 622 can light up to indicate that a call is in progress.

[0259] In some embodiments, the light-emitting element 622 may illuminate to indicate that the microphone assembly 80 is in an on or off state. The light-emitting element 622 may also illuminate to indicate the switching process of the microphone 82. The light-emitting element 622 may illuminate to indicate that the headphones 1 are playing music or are in a muted state.

[0260] The above description is only a part of the embodiments of this application and does not limit the scope of protection of this application. Any equivalent device or equivalent process transformation made based on the content of this application specification and drawings, or direct or indirect application in other related technical fields, are similarly included in the patent protection scope of this application.
