Abstract

This application relates to an earphone, specifically to the field of sound-generating devices. The earphone includes a first housing assembly, a second housing assembly, an ear loop, and a radio frequency (RF) circuit. The ear loop includes an elastic element and an antenna. One end of the elastic element is connected to the first housing assembly, and the other end is connected to the second housing assembly. The RF circuit is disposed within the first housing assembly and / or within it. The RF signal output by the RF circuit is radiated via the antenna. The antenna is attached to the elastic element and is insulated from it. This application utilizes the advantage that the ear loop is further away from the user's skin compared to the first and second housing assemblies.

Description

Technical Field

[0001] This application relates to the field of sound-producing device technology, and in particular to an earphone. Background Technology

[0002] Currently, the main types of open-back headphones are ear-hook, ear clip, and behind-the-ear. For headphones equipped with antennas, the antenna's SAR (Specific Absorption Ratio) is relatively high, and the antenna performance is relatively poor, which greatly affects the user's headphone experience. Summary of the Invention

[0003] This application provides an earphone, which includes a first housing assembly, a second housing assembly, an ear loop, and a radio frequency circuit. The ear loop includes an elastic element and an antenna. One end of the elastic element is connected to the first housing assembly, and the other end is connected to the second housing assembly. The radio frequency circuit is disposed within the first housing assembly and / or the first housing assembly. The radio frequency signal output by the radio frequency circuit is configured to be radiated through the antenna. The antenna is attached to the elastic element and is insulated from it.

[0004] The beneficial effects of this application are as follows: This application utilizes the advantage that the area around the ear is further away from the user's skin compared to the first and second housing components. By placing the antenna on the area around the ear, the internal space of the area is utilized, and the difficulty of antenna installation is reduced. Compared to placing the antenna inside the first and second housing components, placing the antenna on the area around the ear allows the antenna to be farther from the user's ear and head. Consequently, the antenna 3 is less affected by the user's ear and head, resulting in a lower SAR value and better antenna performance. Attached Figure Description

[0021] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be noted that the following embodiments are for illustrative purposes only and do not limit the scope of the application. Similarly, the following embodiments are only some, not all, embodiments of the present application, and all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present application.

[0022] The reference to "embodiment" in this application means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0023] Furthermore, the technical solutions of the various embodiments can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0024] Please see Figure 1 , Figure 1 This is a schematic diagram illustrating the wearing of headphones on a user's ear in some embodiments of this application. The user's ear 100 may include physiological parts such as the external auditory canal 101, concha 102, cymba conchae 103, triangular fossa 104, antihelix 105, scaphoid fossa 106, helix 107, and antitragus 108. Although the external auditory canal 101 has a certain depth and extends to the tympanic membrane of the ear 100, for ease of description and in conjunction with... Figure 1 Unless otherwise specified, in this application, the external auditory canal 101 specifically refers to the entrance (i.e., ear hole) of the external auditory canal 101 away from the tympanic membrane.

[0025] Furthermore, physiological sites such as the concha 102, cymba conchae 103, and triangular fossa 104 have a certain volume and depth. The concha 102 is directly connected to the external auditory canal 101, which means that the aforementioned ear opening can be simply regarded as being located at the bottom of the concha 102.

[0026] Furthermore, the outer periphery of the external auditory canal 101 of the ear 100 also includes a tragus 109, which, compared to the concha 102, cymba conchae 103, and triangular fossa 104, possesses a certain depth and volume in three-dimensional space. That is, these parts are recessed towards the posterior side of the ear 100 along the direction closer to the user's head, while the tragus 109 protrudes towards the anterior side of the ear 100 along the direction away from the user's head. Here, "anterior side of the ear" is a concept relative to "posterior side of the ear." The former refers to the side of the ear 100 away from the head, for example... Figure 1 The latter refers to the side of the ear facing the head; both are aimed at the user's ear.

[0027] Furthermore, individual differences may exist among different users, resulting in variations in the shape, size, and other dimensions of the ear 100. For ease of description and to reduce (or even eliminate) these individual differences, unless otherwise specified, this application will primarily refer to an ear model with a "standard" shape and size, such as... Figure 1 The ear 100 shown can be an ear model. The wearing method of the earphone 200 in different embodiments on this ear model is further described. For example, a simulator containing a head and ears (left and / or right ear) 100, such as the GRAS 45BC KEMAR, can be made based on ANSI: S3.36, S3.25 and IEC: 60318-7 standards as a reference for wearing the earphone 200, thereby representing the scenario of most users normally wearing the earphone 200.

[0028] Therefore, descriptions such as "worn by the wearer," "in a wearing state," and "under wearing condition" in this application refer to the earphone 200 being worn on the ear 100 of the ear model. Of course, considering individual differences among users, the structure, shape, size, thickness, etc., of one or more parts of the ear 100 may vary. To meet the needs of different users, the earphone 200 can be designed differently. These differences can be manifested in the characteristic parameters of one or more structures in the earphone 200 having different ranges of values, thereby adapting to different ear 100s.

[0029] It should be noted that 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, the coronal axis, and the vertical axis. 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 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 is the axis along the vertical direction of the body and perpendicular to the horizontal plane.

[0030] Furthermore, the "front side of the ear" mentioned in this application is a concept relative to "back side of the ear." The former refers to the side of the ear 100 that faces away from the head, while the latter refers to the side of the ear 100 that faces the head; both refer to the user's ear 100. Specifically, by observing the ear 100 of the ear model along the direction of the human coronal axis, one can obtain... Figure 1 The ear portion 100 is shown.

[0031] Please see Figure 1 , Figure 2 and Figure 3 , Figure 2 for Figure 1 The illustrated embodiment shows a schematic diagram of the structure of the earphone 200 in some embodiments. Figure 3 for Figure 2 The illustrated embodiment shows an exploded view of a portion of the structure of the earphone 200 in some embodiments. The earphone 200 may include a first housing assembly 11, a second housing assembly 21, and an ear loop 30. The two ends of the ear loop 30 are respectively connected to the first housing assembly 11 and the second housing assembly 21.

[0032] When worn, the first housing assembly 11 abuts against the concha cavity 102, and the second housing assembly 21 abuts against the back of the auricle, wrapping around the ear 30 and surrounding the outer side of the helix 107 to provide clamping force for the first housing assembly 11 and the second housing assembly 21, so that the first housing assembly 11 and the second housing assembly 21 can cooperate to clamp each other, thereby clamping the entire earphone 200 in the ear 100. The first housing assembly 11 and the second housing assembly 21 can form a clamping state on both sides of the ear 100.

[0033] In some embodiments, the ear portion 30 transitions smoothly along its extension direction. Here, "smooth transition" means that the shape, diameter, curvature angle, or direction of the ear portion 30 changes gradually in the extension direction, avoiding abrupt geometric changes. Further, in some embodiments, "smooth transition" means that the diameter of the smallest circumscribed circle (i.e., the smallest outer diameter) of the ear portion 30 in a section perpendicular to the extension direction changes gradually, avoiding abrupt geometric changes. Further, in some embodiments, "smooth transition" means that the abrupt change rate of the diameter of the smallest circumscribed circle (i.e., the smallest outer diameter) of the ear portion 30 in a section perpendicular to the extension direction is less than or equal to 10%. In some embodiments, "smooth transition" means that the abrupt change rate of the diameter of the smallest circumscribed circle (i.e., the smallest outer diameter) of the ear portion 30 in a section perpendicular to the extension direction is less than or equal to 5%. In some embodiments, the portion of the ear portion 30 exposed relative to the first housing assembly 11 and the second housing assembly 21 transitions smoothly along its extension direction.

[0034] Please see Figure 3 The ear portion 30 may include an elastic element 31. The elastic element 31 may serve as the main body of the ear portion 30 and may provide the ear portion 30 with the ability to elastically deform. The two ends of the elastic element 31 are respectively connected to the first housing assembly 11 and the second housing assembly 21.

[0035] When worn, the first housing assembly 11 abuts against the concha cavity 102, and the second housing assembly 21 abuts against the back of the auricle. The elastic member 31 is wrapped around the outside of the helix 107 to provide clamping force for the first housing assembly 11 and the second housing assembly 21, so that the first housing assembly 11 and the second housing assembly 21 can cooperate to clamp each other, thereby clamping the entire earphone 200 in the ear 100. The first housing assembly 11 and the second housing assembly 21 can form a clamping state on both sides of the ear 100.

[0036] In some embodiments, the first housing assembly 11, the second housing assembly 21, and the elastic member 31 may be arranged to form a wearing space 201 so that when the ear 100 is inserted into the wearing space 201, the earphone 200 is worn entirely on the ear 100.

[0037] In some embodiments, the headphones 200 may be clip-on headphones.

[0038] In some embodiments, please refer to Figure 2The headphones 200 may further include a speaker 12, which may be disposed in the first housing assembly 11 and output sound to the outside of the first housing assembly 11 through a sound outlet on the first housing assembly 11. It is understood that the first housing assembly 11 and the speaker 12 may constitute a sound-emitting element 10 and serve as part of the headphones 200. Of course, the sound-emitting element 10 may not be limited to the first housing assembly 11 and / or the speaker 12, and may include others, which will not be elaborated further. In some embodiments, the sound-emitting element 10 may further include a microphone 13 disposed within the first housing assembly 11, which may receive sound from outside the first housing assembly 11 through a sound pickup hole on the first housing assembly 11.

[0039] In some embodiments, please refer to Figure 3 The earphone 200 may also include a battery 22, which may be disposed within the second housing assembly 21 to power the earphone 200, for example, the speaker 12 and the microphone 13, for normal operation. It is understood that the second housing assembly 21 and the battery 22 may form an abutment 20 and be part of the earphone 200. Of course, the abutment 20 may not be limited to the second housing assembly 21 and / or the battery 22, and may include others, which will not be elaborated further. In some embodiments, the abutment 20 may also include a mainboard 23 disposed within the second housing assembly 21, which may be connected to the battery 22, the speaker 12, the microphone 13, etc. In some embodiments, the mainboard 23 may be used to control the operation of the speaker 12. In some embodiments, the mainboard 23 may be used to control the operation of the microphone 13.

[0040] In some embodiments, please refer to Figure 3 The earphone 200 may also include an elastic covering layer 32. The elastic covering layer 32 may cover the elastic member 31 and extend towards the side near the first housing assembly 11 and / or the second housing assembly 21, so that in a further embodiment it may cover at least a portion of the first housing assembly 11 and / or the second housing assembly 21, improving the appearance consistency of the earphone 200. It is understood that the elastic member 31 and the elastic covering layer 32 may form an ear wrap 30 and be part of the earphone 200. Of course, the ear wrap 30 may not be limited to the elastic member 31 and / or the elastic covering layer 32, and may include others, which will not be elaborated further.

[0041] In a further embodiment, the elastic covering layer 32 is provided such that the exposed portions of the ear portion 30 relative to the first housing assembly 11 and the second housing assembly 21 transition smoothly in the extension direction.

[0042] In some embodiments, the elastic covering layer 32 can improve the appearance and feel of the earpiece 30. The elastic covering layer 32 may be made of flexible materials such as silicone, plastic, foam, etc.

[0043] In some embodiments, please refer to Figure 1, Figure 2 and Figure 3 The earphone 200 may include a sound-emitting element 10, an abutment 20, and an ear loop 30. The ear loop 30 connects the sound-emitting element 10 and the abutment 20. When worn, the sound-emitting element 10 may be disposed within the concha 102, the abutment 20 abuts against the back of the auricle, and the ear loop 30 is wrapped around the outside of the helix 107 to provide clamping force for the sound-emitting element 10 and the abutment 20, so that the sound-emitting element 10 and the abutment 20 can cooperate to clamp each other, thereby clamping the entire earphone 200 in the ear 100.

[0044] In some embodiments, the sound-emitting element 10, the abutment element 20, and the ear-encircling part 30 may be arranged to form a wearing space 201 so that when the ear 100 is inserted into the wearing space 201, the earphone 200 is worn entirely on the ear 100.

[0045] Please see Figure 4 , Figure 4 This is a partial circuit diagram of the earphone 200 in some embodiments of this application. The earphone 200 may also include a radio frequency (RF) circuit 231 and an antenna 34. The RF signal output by the RF circuit 231 can be radiated through the antenna 34 to enable communication between the earphone 200 and an external device. The RF circuit 231 may be disposed within the first housing assembly 11 and / or the second housing assembly 21. The antenna 34 may be disposed on the elastic member 31.

[0046] In some embodiments, the radio frequency circuit 231 may be part of the sound-emitting element 10 or the abutment element 20. In some embodiments, the radio frequency circuit 231 may be disposed on the motherboard 23. In some embodiments, the antenna 34 may be part of the ear loop 30.

[0047] Please see Figure 5 , Figure 5 for Figure 3 The illustrated embodiment shows a schematic diagram of the structure in which the elastic element 31 and the antenna 34 cooperate. The antenna 34 can be attached to the elastic element 31 and is insulated from it. This application utilizes the advantage that the ear-wrap 30 is further away from the user's skin than the first housing assembly 11 and the second housing assembly 21. By setting the antenna 34 on the ear-wrap 30, for example, the elastic element 31, the internal space of the ear-wrap 30 can be utilized, and the difficulty of setting the antenna 34 can be reduced by this internal space. Compared with the antenna 34 being set inside the first housing assembly 11 and the second housing assembly 21, the antenna 34 being set on the ear-wrap 30, for example, the elastic element 31, allows the antenna 34 to be farther away from the user's ear 100 and head, thus the antenna 34 is less affected by the user's ear 100 and head, resulting in a lower SAR value and better antenna performance.

[0048] Please see Figure 6 , Figure 6 for Figure 5The illustrated embodiment shows a schematic cross-sectional view of the line VI-VI when the elastic element 31 and antenna 34 are engaged. A cross-section perpendicular to the length extension direction X of the elastic element 31 is shown below. Figure 6 As shown. The cross-section can have a width direction (Y) and a height direction (Z).

[0049] In some embodiments, an insulating layer 3401 may be provided between the antenna 34 and the elastic member 31 to improve the electrical isolation between the antenna 34 and the elastic member 31 and reduce the influence of the elastic member 31 on the radiation performance of the antenna 34. In some embodiments, when an insulating covering layer is provided on the outer surface of the elastic member 31, the antenna 34 and the elastic member 31 can be insulated, and the insulating layer 3401 may not be provided. In some embodiments, when the elastic member 31 is made of an insulating material, the antenna 34 and the elastic member 31 can be insulated, and the insulating layer 3401 may not be provided. In some embodiments, when an insulating covering layer is provided on the outer surface of the antenna 34, the insulating layer 3401 may not be provided.

[0050] In some embodiments, the insulating layer 3401 may be a flexible material and may have the ability to elastically deform. In some embodiments, the insulating layer 3401 may be an adhesive to achieve the connection between the antenna 34 and the elastic member 31. In some embodiments, the insulating layer 3401 may be formed during surface pretreatment of the elastic member 31 in order to attach the antenna 34.

[0051] In some embodiments, the elastic member 31 may be partially or entirely made of metal. Alternatively, the elastic member 31 may be made of metal at least at the location where the antenna 34 is attached. The provision of the insulating layer 3401 can then insulate the antenna 34 from the elastic member 31, reducing the impact of the elastic member 31 on the antenna 34. Of course, if the elastic member 31 is made of non-metal at least at the location where the antenna 34 is attached, the antenna 34 can be directly mounted on the non-metallic surface without the need for the insulating layer 3401.

[0052] In some embodiments, part or all of the elastic element 31 is a metal element, or the elastic element 31 may be a metal element at least at the part attached to the antenna 34, thereby enabling the elastic element 31 to also radiate. Furthermore, the radio frequency signal output by the radio frequency circuit 231 can be loaded onto the elastic element 31 by electromagnetic coupling through the antenna 34, thereby improving the antenna performance of the earphone 200 by utilizing the metal part of the elastic element 31.

[0053] In some embodiments, the antenna 34 may be a plating layer attached to the elastic member 31. For example, the plating layer is formed on the elastic member 31 by electroplating, serving as the antenna 34. For example, the metal (such as copper, zinc, etc.) is deposited on the surface of the elastic member 31 using the principle of electrolysis, forming the antenna 34. For example, the plating layer is formed on the elastic member 31 by chemical plating, serving as the antenna 34. For example, the antenna 34 is formed on the elastic member 31 by a uniform plating layer through an autocatalytic reaction. For example, the plating layer is formed on the elastic member 31 by spraying, serving as the antenna 34. For example, the plating layer is formed on the elastic member 31 by thermal spraying or electrostatic spraying, serving as the antenna 34. For example, the plating layer is formed on the elastic member 31 by physical vapor deposition (PVD) or chemical vapor deposition (CVD), serving as the antenna 34. Of course, the specific plating process is not limited to the plating processes listed herein, and may also be other plating processes well known to those skilled in the art. In addition, in order to form the plating layer, it is not necessary to use only the plating processes listed herein, but multiple plating processes can be combined to form the plating layer.

[0054] In some embodiments, the antenna 34 may be a flexible circuit board attached to the elastic member 31. The flexible circuit board may be attached by processes well known to those skilled in the art, such as adhesive bonding, mechanical fastening (e.g., snap-fit / binding), welding / pressing, or thermoforming.

[0055] In some embodiments, the antenna 34 may be a coating attached to the elastic member 31. A composite paste containing conductive paste may be prepared in advance, and then the composite paste may be applied to the elastic member 31 to form the antenna 34. In some embodiments, the composite paste may also include binders, solvents, and additives, and the composite paste may be prepared according to techniques well known to those skilled in the art. In some embodiments, the binder may include organic adhesives and / or inorganic adhesives. In some embodiments, the additives may include dispersants, thickeners, antioxidants, or curing agents. In some embodiments, the conductive paste may include pastes well known to those skilled in the art, such as silver paste, gold paste, copper paste, or carbon paste.

[0056] Please see Figure 6 and Figure 7 , Figure 7 for Figure 6 The diagram illustrates the structure of the elastic element 31 in conjunction with the antenna 34 in other embodiments. The elastic element 31 may be in the form of a sheet, and further in a more advanced embodiment, it may be a sheet-like body.

[0057] Antenna 34 can be attached to the main surface of one side of the elastic member 31. In some embodiments, such as Figure 6As shown, antenna 34 can be attached to one side of the main surface of elastic member 31 in the height direction Z. To reduce the SAR value and improve antenna performance, in a further embodiment, antenna 34 can be attached to the main surface of elastic member 31 on the side opposite to the wearing space 201 in the height direction Z. Of course, in other embodiments, antenna 34 can also be attached to the main surface of elastic member 31 on the side closer to the wearing space 201 in the height direction Z. In some embodiments, such as... Figure 7 As shown, the antenna 34 can also be attached to the main surface of one side of the elastic member 31 in the width direction Y.

[0058] When the antenna 34 is attached to the elastic member 31, the bending caused by the elastic deformation of the elastic member 31 will also cause the antenna 34 to bend. To reduce the risk of damage to the antenna 34 due to the bending of the elastic member 31, in a further embodiment, the antenna 34 can be centrally positioned relative to the elastic member 31 along the width direction Y of the elastic member 31. The middle part of the elastic member 31 in the width direction Y is the part with the smallest degree of torsional deformation, thus having a smaller impact on the overall shape of the antenna 34 during torsional deformation, better ensuring the antenna performance of the antenna 34. In addition, it can also improve the adhesion of the antenna 34 to the elastic member 31 and reduce the risk of the antenna 34 falling off due to torsional deformation. Of course, in other embodiments, the antenna 34 can also be centrally positioned relative to the elastic member 31 along the height direction Z of the elastic member 31. Furthermore, the middle part of the elastic member 31 in the height direction Z is the part with the smallest degree of torsional deformation and / or bending, thus having a smaller impact on the overall shape of the antenna 34 during torsional deformation and / or bending, better ensuring the antenna performance of the antenna 34.

[0059] Please see Figure 8 and Figure 9 , Figure 8 for Figure 6 The diagram shown illustrates the structure of the elastic element 31 and antenna 34 in some other embodiments. Figure 9 for Figure 8 The illustrated embodiment shows a schematic diagram of the structure of the elastic element 31 and antenna 34 in cooperation in other embodiments. The elastic element 31 can be tubular or columnar, or of course, other structural forms, which will not be elaborated further. In some embodiments, the antenna 34 can be attached to the outer wall surface of the elastic element 31. In order to reduce the SAR value and improve antenna performance, in a further embodiment, the antenna 34 can be attached to the outer wall surface of the elastic element 31 on the side away from the wearing space 201 in the height direction Z. Of course, in other embodiments, the antenna 34 can also be attached to the outer wall surface of the elastic element 31 on the side closer to the wearing space 201 in the height direction Z. Furthermore, this can also improve the adhesion of the antenna 34 to the elastic element 31 and reduce the risk of the antenna 34 falling off. In some embodiments, such as Figure 7As shown, the antenna 34 can also be attached to the outer wall surface of one side of the elastic member 31 in the width direction Y. When the antenna 34 is attached to the elastic member 31, the bending caused by the elastic deformation of the elastic member 31 will also cause the antenna 34 to bend. In order to reduce the risk of damage to the antenna 34 due to the bending of the elastic member 31, in a further embodiment, the antenna 34 can be centrally positioned relative to the elastic member 31 along the width direction Y of the elastic member 31. Furthermore, such a configuration can also improve the adhesion of the antenna 34 to the elastic member 31 and reduce the risk of the antenna 34 falling off. Of course, in other embodiments, the antenna 34 can also be centrally positioned relative to the elastic member 31 along the height direction Z of the elastic member 31.

[0060] Please see Figure 8 and Figure 9 Along the length direction X of the elastic member 31, the antenna 34 can be arranged in a linear shape. In the cross-section, the minimum outer diameter R1 of the elastic member 31 can be the diameter of the minimum circumcircle of the cross-section. The ratio of the maximum width R2 of the antenna 34 to the minimum outer diameter R1 of the elastic member 31 is between 0.4 and 0.9, so that the antenna 34 is wider and the radiation capability is improved.

[0061] Please see Figure 10 , Figure 10 for Figure 3 The illustrated embodiment shows a schematic diagram of the structure of the elastic element 31 in some embodiments. The elastic element 31 may include a first elastic segment 311 and a second elastic segment 312. Along the length direction X of the elastic element 31 (e.g., ...) Figure 3 As shown), the first elastic segment 311 and the second elastic segment 312 can be connected to each other.

[0062] In its natural state (i.e., non-wearing state, not worn on any object), the first housing assembly 11 and the second housing assembly 21 can be spaced apart, so that the earpiece 30, for example, the elastic member 31, may not have elastic deformation. Of course, the first housing assembly 11 and the second housing assembly 21 can also abut against each other, so that the earpiece 30, for example, the elastic member 31, can have elastic deformation.

[0063] In some embodiments, the elastic deformation coefficient of the portion of the earpiece 30 corresponding to the second elastic segment 312 is greater than the elastic deformation coefficient of the portion of the earpiece 30 corresponding to the first elastic segment 311. Here, "elastic deformation coefficient" refers to the rate of change of distance between the two ends of a portion / component before and after the earphone 200 expands, i.e., (distance after expansion - distance before expansion) / distance before expansion. Here, the expansion of the earphone 200 refers to the expansion of the first housing assembly 11 and the second housing assembly 21 away from each other. This arrangement allows for the redistribution or concentration of deformation portions of the earpiece 30, resulting in more deformation distributed on the portion of the earpiece 30 corresponding to the second elastic segment 312. Additionally, it facilitates the addition of other structures, such as antennas, circuits, flexible circuit boards, plating, coatings, etc., to the portion of the earpiece 30 corresponding to the first elastic segment 311.

[0064] In some embodiments, the earphone 200 is expanded before its natural state and after its wearing state. Further in some embodiments, in the wearing state, the first housing assembly 11 and the second housing assembly 21 can clamp onto the ear 100, and the clamping force is provided by the ear-wrap portion 30 under elastic deformation, resulting in a greater distance between the two ends of the ear-wrap portion 30 compared to the natural state. Furthermore, the elastic deformation coefficient of the portion of the ear-wrap portion 30 corresponding to the first elastic segment 311 and / or the second elastic segment 312 when switching from the natural state to the wearing state is (distance in the wearing state - distance in the natural state) / distance in the natural state.

[0065] In some embodiments, when other structures such as antennas, circuits, flexible circuit boards, plating, coatings, etc., are attached to the ear loop 30, the bending caused by the elastic deformation of the ear loop 30 will also cause the other structures to bend simultaneously. If the other structures cannot adapt to large-amplitude bending or cannot bend at all, they will be damaged due to the bending of the ear loop 30. In order to attach other structures to the ear loop 30 and to reduce the impact of the bending of the ear loop 30 on the other structures, it is necessary to redistribute and / or concentrate the deformable parts of the ear loop 30 so that other structures can be attached to the less deformable parts of the ear loop 30.

[0066] In some embodiments, the elastic covering layer 32 may cover all or part of the elastic member 31. In some embodiments, the elastic covering layer 32 may cover all or part of the first elastic segment 311. In some embodiments, the elastic covering layer 32 may cover all or part of the second elastic segment 312.

[0067] In some embodiments, when the earphone 200 is in the wearing state, the first housing assembly 11 and the second housing assembly 21 can be clamped onto the ear 100, and the clamping force is provided by the elastic member 31 under elastic deformation. Therefore, the distance O between the two ends of the elastic member 31 is greater in the wearing state compared to the natural state. Consequently, the elastic deformation coefficient O1 of the elastic member 31 when switching from the natural state to the wearing state is |D1|. 佩戴状态 -D1 自然状态 | / D1 自然状态 .

[0068] In some embodiments, the distance between the two ends of the first elastic segment 311 is D2, and the elastic deformation coefficient O2 of the first elastic segment 311 is |D2|. 佩戴状态 -D2 自然状态 | / D2 自然状态 .

[0069] In some embodiments, the distance between the two ends of the second elastic segment 312 is D3, and the elastic deformation coefficient O3 of the second elastic segment 312 is |D3|. 佩戴状态 -D3 自然状态 | / D3 自然状态 .

[0070] In some embodiments, when an antenna 34 is attached to the elastic member 31, the bending caused by the elastic deformation of the elastic member 31 will also cause the antenna 34 to bend. If the antenna 34 cannot adapt to large-amplitude bending or cannot bend at all, it will be damaged or its performance will be reduced due to the bending of the elastic member 31. In order to attach the antenna 34 to the elastic member 31 and to reduce the impact of the bending of the elastic member 31 on the antenna 34, it is necessary to redistribute and / or concentrate the deformable parts of the elastic member 31 so that the antenna 34 can be attached to the less deformable part 2 of the elastic member 31. Then, the first elastic segment 311 and the second elastic segment 312 are adjusted so that when the elastic member 31 switches from the natural state to the wearing state, the elastic deformation coefficient of the second elastic segment 312 is greater than that of the first elastic segment 311, that is, O3 > O2. This makes the first elastic segment 311 more suitable for attaching the antenna 34 because it is less deformable than the second elastic segment 312.

[0071] Furthermore, in some embodiments, the elastic deformation of the earpiece 30 is mainly provided by the elastic element 31. Therefore, based on O3 > O2, when the earphone 200 switches from the natural state to the wearing state, the elastic deformation coefficient of the part of the earpiece 30 corresponding to the second elastic segment 312 should be greater than the elastic deformation coefficient of the part of the earpiece 30 corresponding to the first elastic segment 311.

[0072] In some embodiments, the first elastic segment 311 can connect to one of the first housing assembly 11 and the second housing assembly 21, while the second elastic segment 312 can connect to the other one. In some embodiments, the first housing assembly 11 can be plugged into the first elastic segment 311, and the second housing assembly 21 can be plugged into the second elastic segment 312. Therefore, when the first elastic segment 311 is more difficult to deform than the second elastic segment 312, the connection strength between the first housing assembly 11 and the first elastic segment 311 can be better than the connection strength between the second housing assembly 21 and the second elastic segment 312, and the connection stability between the first housing assembly 11 and the first elastic segment 311 can be better than the connection stability between the second housing assembly 21 and the second elastic segment 312.

[0073] In some embodiments, the first elastic segment 311 and the second elastic segment 312 may be adjusted based on the material and / or structure such that the elastic deformation coefficient of the second elastic segment 312 is greater than that of the first elastic segment 311, i.e., O3 > O2.

[0074] For example, in some embodiments, the material of the first elastic segment 311 is different from the material of the second elastic segment 312. For example, in some embodiments, the first elastic segment 311 may be a plastic part, and the second elastic segment 312 may be a metal part. Of course, the design of the materials of the first elastic segment 311 and the second elastic segment 312 only needs to satisfy O3 > O2, and is not limited to the embodiments listed herein. Furthermore, in further embodiments, the first elastic segment 311 may at least include a plastic part. Furthermore, in further embodiments, the second elastic segment 312 may at least include a metal part.

[0075] For example, in some embodiments, the size and shape of the first elastic segment 311 differ from those of the second elastic segment 312. For example, in some embodiments, the minimum outer diameter of the first elastic segment 311 is greater than the minimum outer diameter of the second elastic segment 312. For example, in some embodiments, the first elastic segment 311 is a tubular body, and the second elastic segment 312 is a sheet-like body. By utilizing the characteristics of sheet-like bodies being more easily deformable and tubular bodies being less easily deformable, the distribution and concentration of deformable portions in the elastic element 31 are achieved, further enabling deformation to be achieved primarily through sheet-like bodies. Of course, the design of the size and shape of the first elastic segment 311 and the second elastic segment 312 only needs to satisfy O3 > O2, and is not limited to the embodiments listed herein.

[0076] In some embodiments, the tubular body may be a round tubular body, a square tubular body, or other forms of tubular body.

[0077] In some embodiments, the first elastic segment 311 may be a metal tubular body. In some embodiments, the second elastic segment 312 may be a metal sheet. Furthermore, in a further embodiment, the first elastic segment 311 may at least include a metal tubular body. Furthermore, in a further embodiment, the second elastic segment 312 may at least include a metal sheet.

[0078] In some embodiments, when the size, shape, etc. of the first elastic segment 311 differs from the size, shape, etc. of the second elastic segment 312, the materials of the first elastic segment 311 and the second elastic segment 312 may be the same; for example, both the first elastic segment 311 and the second elastic segment 312 may be plastic or metal. Of course, the materials of the first elastic segment 311 and the second elastic segment 312 may also be different.

[0079] In some embodiments, when the material of the first elastic segment 311 is different from the material of the second elastic segment 312, both the first elastic segment 311 and the second elastic segment 312 may be tubular or sheet-like. Of course, the size, shape, etc. of the first elastic segment 311 and the second elastic segment 312 may also be different.

[0080] Please see Figure 11 , Figure 11 for Figure 3 The illustrated embodiment shows a cross-sectional view of the second elastic segment 312 along line XI-XI. The second elastic segment 312 is a sheet-like body. A cross-section perpendicular to the length extension direction X of the second elastic segment 312 is shown below. Figure 11 As shown, the cross-section has a width direction Y and a height direction Z. The ratio of the height distance N2 of the outer contour of the cross-section in the height direction Z to the width distance N1 in the width direction Y is less than 0.6.

[0081] Understandably, in this application, for elastic elements 31, such as the first elastic segment 311 and the second elastic segment 312, only when the ratio of the height distance N2 in the height direction Z to the width distance N1 in the width direction Y of the cross-sectional outer contour is less than 0.6 can it be called a sheet-like body. Furthermore, when the ratio of the height distance N2 in the height direction Z to the width distance N1 in the width direction Y of the cross-sectional outer contour is between 0.6 and 1.2, it can be called a tubular body.

[0082] Please see Figure 12 , Figure 12 for Figure 4 The illustrated embodiment shows a schematic cross-sectional view of the second elastic segment 312 along line XII-XII. The first elastic segment 311 is a tubular body. The minimum outer diameter of the first elastic segment 311 can be R1. Please refer to... Figure 11 and Figure 12The ratio of the maximum width N1 of the second elastic segment 312 to the minimum outer diameter R1 of the first elastic segment 311 is between 0.4 and 0.9, making the second elastic segment 312 narrower in the width direction, which facilitates subsequent processing to form the ear-like portion 30 and improves the appearance. For example, the second elastic segment 312 can be inserted into the first elastic segment 311. For example, after covering the second elastic segment 312 with an elastic covering layer 32, its appearance size can be consistent with that of the first elastic segment 311. Furthermore, when the first elastic segment 311 is also covered with an elastic covering layer 32, the overall consistency of the appearance of the ear-like portion 30 can be improved. It is understood that a ratio between 0.4 and 0.9 may include 0.4 or 0.9.

[0083] Please see Figure 10 In some embodiments, the ratio of the total length L1 of the first elastic segment 311 to the total length (L1+L2) of the elastic member 31 is between 0.35 and 0.65, so that the first elastic segment 311 can be exposed outside the first housing assembly 11 and the second housing assembly 21, thereby improving the structural strength of the earphone 200, improving the connection strength and connection stability of the first housing assembly 11, the second housing assembly 21, and the elastic member 31, and further concentrating the deformation on the second elastic segment 312.

[0084] In some embodiments, the first elastic segment 311 and the second elastic segment 312 can be integrated in structural design and can be manufactured as a whole through one or more processes such as welding, bolting, riveting, etc., which can simplify the processing difficulty of the elastic component 31 and improve production efficiency.

[0085] In some embodiments, the first elastic segment 311 and the second elastic segment 312 can be integrally molded using a one-piece molding process to form an integral structure. An integral molding process refers to processing multiple parts or components of a product into a single, complete, and indivisible structure through a specific process. For example, the first elastic segment 311 and the second elastic segment 312 can be directly formed into a complete component using molding technologies such as injection molding, die casting, or 3D printing, without the need for assembly. Further, in some embodiments, the first elastic segment 311 is, for example, a metal tubular body, and the second elastic segment 312 is, for example, a metal sheet, integrally molded.

[0086] In some embodiments, the first elastic segment 311 and the second elastic segment 312 can be connected by connection methods well known to those skilled in the art, such as insertion, welding, bonding, or snap-fit. In some embodiments, when the first elastic segment 311 is a tubular body and the second elastic segment 312 is a sheet-like body, a portion of the sheet-like body can be inserted into the tubular body, simplifying the connection between the first elastic segment 311 and the second elastic segment 312, achieving a stable connection between the first elastic segment 311 and the second elastic segment 312, and further improving the connection strength between the first elastic segment 311 and the second elastic segment 312. In some embodiments, a portion of the second elastic segment 312, for example, a metal sheet-like body, is inserted into the first elastic segment 311, for example, a metal tubular body.

[0087] In some embodiments, the first elastic segment 311 may connect at least one of the two housing components, the first housing component 11 and the second housing component 21. In a further embodiment, at least one of the two housing components, the first housing component 11 and the second housing component 21, is integrally formed with the first elastic segment 311, and the first elastic segment 311 and the second elastic segment 312 may cooperate to form the outer surface of the ear portion 30, so that the exposed portion of the ear portion 30 relative to the first housing component 11 and the second housing component 21 smoothly transitions along the extension direction from the first housing component 11 to the second housing component 21.

[0088] In some embodiments, the first elastic segment 311 may be a plastic part, and at least one of the two housing assemblies, the first housing assembly 11 and the second housing assembly 21, is integrally formed with the first elastic segment 311.

[0089] In some embodiments, the elastic covering layer 32 may cover at least the outside of the second elastic segment 312, and the first elastic segment 311 and the elastic covering layer 32 may cooperate to form the outer surface of the ear portion 30, or the elastic covering layer 32 may form the outer surface of the ear portion 30 (i.e., the elastic covering layer 32 may cover the first elastic segment 311 and the second elastic segment 312 together), so that the exposed portion of the ear portion 30 relative to the first housing assembly 11 and the second housing assembly 21 smoothly transitions along the extension direction from the first housing assembly 11 to the second housing assembly 21.

[0090] Please see Figure 13 , Figure 13 for Figure 10 The illustrated embodiment shows a schematic diagram of the structure of the elastic element 31 in other embodiments. The first elastic segment 311 may include a first sub-elastic segment 3111 and a second sub-elastic segment 3112. Along the length direction X of the elastic element 31, the first sub-elastic segment 3111, the second elastic segment 312 and the second elastic segment 3112 may be connected sequentially.

[0091] In some embodiments, the first sub-elastic segment 3111 can be connected to the first housing assembly 11, and the second sub-elastic segment 3112 can be connected to the second housing assembly 21, such that the second elastic segment 312 is located between the first sub-elastic segment 3111 and the second sub-elastic segment 3112, concentrating and / or distributing the deformation of the elastic element 31 in the middle, thereby reducing the impact on the connection strength and connection stability between the elastic element 31 and the first housing assembly 11 and the second housing assembly 21. For example, using the more difficult-to-deform first elastic segment 311, such as the first sub-elastic segment 3111 and the second sub-elastic segment 3112, to connect the first housing assembly 11 and the second housing assembly 21 can improve the connection strength and connection stability, thereby enhancing the reliability of the earphone 200. Furthermore, when the first elastic segment 311, such as the first sub-elastic segment 3111 and the second sub-elastic segment 3112, is inserted into the first housing assembly 11 and the second housing assembly 21, the insertion strength and insertion stability are also higher.

[0092] In some embodiments, the distance between the two ends of the first sub-elastic segment 3111 is D21, and when the elastic element 31 switches from the natural state to the wearing state, the elastic deformation coefficient of the first sub-elastic segment 3111 is O. 21 Can be |D21 佩戴状态 -D21 自然状态 | / D21 自然状态 .

[0093] In some embodiments, the distance between the two ends of the second elastic segment 312 is D3, and when the elastic element 31 switches from the natural state to the wearing state, the elastic deformation coefficient O3 of the second elastic segment 312 can be |D3|. 佩戴状态 -D3 自然状态 | / D3 自然状态 .

[0094] In some embodiments, the distance between the two ends of the second sub-elastic segment 3112 is D22, and when the elastic element 31 switches from the natural state to the wearing state, the elastic deformation coefficient of the second sub-elastic segment 3112 is O. 22 Can be |D22 佩戴状态 -D22 自然状态 | / D22 自然状态 .

[0095] In some embodiments, the first elastic segment 311 and the second elastic segment 312 are adjusted such that the elastic deformation coefficient of the second elastic segment 312 is greater than the elastic deformation coefficient of the first sub-elastic segment 3111, that is, O3 > O. 21 This makes the first elastic segment 3111 more difficult to deform than the second elastic segment 312, thus making it more suitable for attaching an antenna 34.

[0096] In some embodiments, the first elastic segment 311 and the second elastic segment 312 are adjusted such that the elastic deformation coefficient of the second elastic segment 312 is greater than the elastic deformation coefficient of the second sub-elastic segment 3112, that is, O3 > O. 22 This makes the second sub-elastic segment 3112 more difficult to deform than the second elastic segment 312, thus making it more suitable for attaching an antenna 34.

[0097] In some embodiments, the first elastic segment 311 and the second elastic segment 312 are adjusted such that the elastic deformation coefficient of the second elastic segment 312 is greater than that of the first elastic segment 311, that is, O3 > |D22|. 佩戴状态 -D22 自然状态 +D21 佩戴状态 -D21 自然状态 | / (D21 自然状态 +D22 自然状态 This makes the first elastic segment 311 more difficult to deform than the second elastic segment 312, thus making it more suitable for attaching an antenna 34.

[0098] In some embodiments, the first sub-elastic segment 3111 may be partially inserted into the first housing assembly 11 to improve the connection strength and connection stability between the first sub-elastic segment 3111 and the first housing assembly 11.

[0099] In some embodiments, the second elastic segment 312 may be partially inserted into the first sub-elastic segment 3111 to improve the connection strength and connection stability between the second elastic segment 312 and the first sub-elastic segment 3111.

[0100] In some embodiments, the second sub-elastic segment 3112 may be partially inserted into the second housing assembly 21 to improve the connection strength and connection stability between the second sub-elastic segment 3112 and the second housing assembly 21.

[0101] In some embodiments, the second elastic segment 312 may be partially inserted into the second sub-elastic segment 3112 to improve the connection strength and connection stability between the second elastic segment 312 and the second sub-elastic segment 3112.

[0102] Please see Figure 14 , Figure 14 for Figure 10 The illustrated embodiment shows a schematic diagram of the elastic element 31 in other embodiments. The second elastic segment 312 may include a third sub-elastic segment 3121 and a fourth sub-elastic segment 3122. Along the length direction X of the elastic element 31, the third sub-elastic segment 3121, the first elastic segment 311, and the fourth sub-elastic segment 3122 may be connected sequentially.

[0103] In some embodiments, the third sub-elastic segment 3121 can be connected to the first housing assembly 11, and the fourth sub-elastic segment 3122 can be connected to the second housing assembly 21, such that the first elastic segment 311 is located between the third sub-elastic segment 3121 and the fourth sub-elastic segment 3122, concentrating and / or distributing the deformation of the elastic member 31 on both sides. Because the first elastic segment 311 in the middle is more difficult to deform, the first elastic segment 311 can improve the structural strength of the middle part of the elastic member 31. When the user holds the headphones 200, they can hold the first elastic segment 311 of the elastic member 31, making the user's holding more comfortable and reliable. In addition, when wearing the headphones 200, wearing can be achieved by causing at least one of the third sub-elastic segment 3121 and the fourth sub-elastic segment 3122 to undergo elastic deformation, making the headphones 200 more convenient to wear.

[0104] In some embodiments, the distance between the two ends of the third sub-elastic segment 3121 is D31, and the elastic deformation coefficient of the third sub-elastic segment 3121 is O. 31 Can be |D31 佩戴状态 -D31 自然状态 | / D31 自然状态 .

[0105] In some embodiments, the distance between the two ends of the fourth sub-elastic segment 3122 is D32, and the elastic deformation coefficient of the fourth sub-elastic segment 3122 is O. 32 Can be |D32 佩戴状态 -D32 自然状态 | / D32 自然状态 .

[0106] In some embodiments, the first elastic segment 311 and the second elastic segment 312 are adjusted such that the elastic deformation coefficient of the third sub-elastic segment 3121 is greater than that of the first elastic segment 311, that is, O 31 >O2, which makes the first elastic segment 311 more difficult to deform than the third sub-elastic segment 3121, and thus more suitable for attaching an antenna 34.

[0107] In some embodiments, the first elastic segment 311 and the second elastic segment 312 are adjusted such that the elastic deformation coefficient of the fourth sub-elastic segment 3122 is greater than that of the first elastic segment 311, that is, O 32 >O2, which makes the first elastic segment 311 more difficult to deform than the fourth sub-elastic segment 3122, and thus more suitable for attaching an antenna 34.

[0108] In some embodiments, the first elastic segment 311 and the second elastic segment 312 are adjusted such that the elastic deformation coefficient of the second elastic segment 312 is greater than that of the first elastic segment 311, that is, |D31 佩戴状态 -D31 自然状态 +D32佩戴状态 -D32 自然状态 | / D32 自然状态 >O2, which makes the first elastic segment 311 more difficult to deform than the second elastic segment 312, and thus more suitable for attaching an antenna 34.

[0109] In some embodiments, the third sub-elastic segment 3121 may be partially inserted into the first housing assembly 11 to improve the connection strength and connection stability between the third sub-elastic segment 3121 and the first housing assembly 11.

[0110] In some embodiments, the third sub-elastic segment 3121 may be partially inserted into the first elastic segment 311 to improve the connection strength and connection stability between the third sub-elastic segment 3121 and the first elastic segment 311.

[0111] In some embodiments, the fourth sub-elastic segment 3122 may be partially inserted into the second housing assembly 21 to improve the connection strength and connection stability between the fourth sub-elastic segment 3122 and the second housing assembly 21.

[0112] In some embodiments, the fourth sub-elastic segment 3122 may be partially inserted into the first elastic segment 311 to improve the connection strength and connection stability between the fourth sub-elastic segment 3122 and the first elastic segment 311.

[0113] The first elastic segment 311 can be integrally formed with the second elastic segment 312. For example, the first elastic segment 311 and the second elastic segment 312 can have the same structure and / or material. During the manufacturing process of the elastic component 31, the first elastic segment 311 can be formed first, and the second elastic segment 312 can be formed by further processing at specific locations of the first elastic segment 311. For example, in... Figure 13 In this process, the second elastic segment 312 can be formed by processing the middle part of the first elastic segment 311. For example, in... Figure 14 In the process, the second elastic segment 312 can be formed by processing on both sides of the first elastic segment 311, such as the third sub-elastic segment 3121 and the fourth sub-elastic segment 3122.

[0114] In some embodiments, the first elastic segment 311 and the second elastic segment 312 may be integrally formed from metal parts.

[0115] In some embodiments, the second elastic segment 312 is configured to be formed by partially opening or flattening a metal part.

[0116] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 3The elastic member 31 may be partially inserted into the sound-emitting member 10, such as the first housing assembly 11, to achieve the connection between the elastic member 31 and the sound-emitting member 10, such as the first housing assembly 11, and to improve the connection strength between the two. In some embodiments, the elastic member 31 may be partially inserted into the abutment member 20, such as the second housing assembly 21, to achieve the connection between the elastic member 31 and the abutment member 20, such as the second housing assembly 21, and to improve the connection strength between the two.

[0117] For example, the second housing assembly 21 may include a housing body 211 and a connecting housing 212. The housing body 211 may serve as the main structure of the second housing assembly 21 to accommodate and install the structure within the abutment 20. The connecting housing 212 may be connected to the housing body 211 and used for insertion with the elastic member 31, such that the elastic member 31 can be partially inserted into the connecting housing 212 to improve the connection strength and stability between the elastic member 31 and the second housing assembly 21, such as the housing body 211. In some embodiments, the elastic covering layer 32 may cover part or all of the connecting housing 212 to improve appearance consistency. In a further embodiment, the elastic covering layer 32 may also allow the exposed portion of the ear portion 30 relative to the first housing assembly 11 and the second housing assembly 21 to smoothly transition along the extension direction from the first housing assembly 11 to the second housing assembly 21.

[0118] Understandably, the first housing assembly 11 may also be configured in the same way as the second housing assembly 21, and may include a housing body and a connecting housing.

[0119] Furthermore, in some embodiments, the elastic member 31 has an exposed portion relative to the sound-generating member 10, such as the first housing assembly 11, and the abutment member 20, such as the second housing assembly 21, and provides clamping force for the sound-generating member 10 and the abutment member 20 through the exposed portion. In a further embodiment, an elastic covering layer 32 covers this exposed portion.

[0120] In some embodiments, please refer to Figure 10 , Figure 10 The diagram shows an exposed portion of the elastic element 31 with a length of L1 + L2. For example, the first elastic segment 311 may be exposed relative to the first housing assembly 11 and the second housing assembly 21, and also exposed relative to the second elastic segment 312, with an exposed portion of length L1. Similarly, the second elastic segment 312 may be exposed relative to the first housing assembly 11 and the second housing assembly 21, and also exposed relative to the first elastic segment 311, with an exposed portion of length L2.
