[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. Ear clip headphones are very comfortable for most users, and they provide clamping force through the elastic deformation around the ear, which makes it difficult to attach other structures such as antennas.

[0004] The beneficial effects of this application are as follows: This application improves the ear-shaped part by redistributing or concentrating the deformed parts of the ear-shaped part, so that the deformation is more distributed on the part of the ear-shaped part corresponding to the second elastic segment, which makes it easier to attach other structures, such as antennas, to the part of the ear-shaped part corresponding to the first elastic segment.

[0022] 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.

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.
[0024] 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.

[0025] 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.
[0026] 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.
[0027] 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.
[0028] 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.
[0029] 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.
[0030] 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.
[0031] 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.
[0032] 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.
[0033] 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.
[0034] 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.
[0035] Please see Figure 2 and 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.
[0036] 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.
[0037] In some embodiments, the headphones 200 may be clip-on headphones.
[0038] Please see Figure 4 , Figure 4 This is 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 around the ear portion 30 (e.g., ...). Figure 3 As shown), the first elastic segment 311 and the second elastic segment 312 can be connected to each other.
[0039] 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, does not have elastic deformation around the ear 30, such as the elastic member 31. 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, can have elastic deformation around the ear 30, such as the elastic member 31.
[0040] 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.
[0041] 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.
[0042] 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.
[0043] 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 an elastic member 31 around the ear 30 under elastic deformation. Therefore, the distance D1 between the two ends of the elastic member 31 is larger 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 .
[0044] In some embodiments, the distance between the two ends of the first elastic segment 311 is D2, and when the elastic element 31 switches from the natural state to the wearing state, 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 .
[0045] 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 is |D3|. 佩戴状态 -D3 自然状态 | / D3 自然状态 .
[0046] In some embodiments, when other structures such as antennas, circuits, flexible circuit boards, plating, coatings, etc. are attached to the elastic member 31 or the ear portion 30 corresponding to the elastic member 31, the bending of the ear portion 30, such as the elastic member 31, due to elastic deformation will also cause other structures to bend. When other structures cannot adapt to large-amplitude bending or cannot be bent, they will be damaged due to the bending of the ear portion 30, such as the elastic member 31. In order to enable the addition of other structures to the elastic member 31 or the ear loop 30 corresponding to the elastic member 31, and in order to reduce the impact of bending of the ear loop 30, such as the elastic member 31, on other structures, it is necessary to redistribute and / or concentrate the deformable parts of the ear loop 30, such as the elastic member 31, so that other structures can be added to the less deformable parts of the elastic member 31 or to the parts of the ear loop 30 corresponding to the less deformable parts. In this way, 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 adding other structures because it is less deformable than the second elastic segment 312. Furthermore, it makes the parts of the ear loop 30 corresponding to the first elastic segment 311 more suitable for adding other structures.
[0047] 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.
[0048] In some embodiments, the first elastic segment 311 can connect to one of the two housing components, the first housing component 11 and the second housing component 21, while the second elastic segment 312 can connect to the other housing component. In some embodiments, the first housing component 11 can be plugged into the first elastic segment 311, and the second housing component 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 component 11 and the first elastic segment 311 can be better than the connection strength between the second housing component 21 and the second elastic segment 312, and the connection stability between the first housing component 11 and the first elastic segment 311 can be better than the connection stability between the second housing component 21 and the second elastic segment 312.
[0049] 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.
[0050] 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.
[0051] 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.
[0052] In some embodiments, the tubular body may be a round tubular body, a square tubular body, or other forms of tubular body.
[0053] 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.
[0054] 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.
[0055] 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.
[0056] In some embodiments, please refer to Figure 3 The earpiece 30 may further 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, allowing the earpiece 30 to transition smoothly in the extension direction. Of course, in other embodiments, it may also improve the aesthetic consistency of the earphone 200. In a further embodiment, the provision of the elastic covering layer 32 allows the earpiece 30 to transition smoothly in the extension direction relative to the exposed portions of the first housing assembly 11 and the second housing assembly 21.
[0057] The elastic covering layer 32 can improve the appearance and feel of the ear wrap 30. The elastic covering layer 32 can be made of flexible materials such as silicone, plastic, foam, etc.
[0058] 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.
[0059] Please see Figure 5 , Figure 5 for Figure 4The illustrated embodiment shows a schematic cross-sectional view of the second elastic segment 312 along line VV. 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 5 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.
[0060] 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.
[0061] In addition, the minimum outer diameter refers to the diameter of the smallest circumscribed circle of the cross-section.
[0062] Please see Figure 6 , Figure 6 for Figure 4 The illustrated embodiment shows a cross-sectional view of the second elastic segment 312 along line VI-VI. The first elastic segment 311 is a tubular body. The minimum outer diameter of the first elastic segment 311 can be R1. In some embodiments, please refer to... Figure 5 and Figure 6 By adjusting the ratio of the maximum width N1 of the second elastic segment 312 to the minimum outer diameter R1 of the first elastic segment 311, the second elastic segment 312 can be made narrower in the width direction, thereby adjusting the elastic deformation of the second elastic segment 312 so that O3 > O2. In addition, it is also convenient to make room for the structure in the ear portion 30 in the width direction of the second elastic segment 312, which facilitates the subsequent addition of structures to the second elastic segment 312 or the portion of the ear portion 30 corresponding to the second elastic segment 312, so that the ear portion 30 can be further processed and formed. Furthermore, in other embodiments, it can also improve the appearance.
[0063] For example, in some embodiments, the second elastic segment 312 is narrower in the width direction, and the second elastic segment 312 can be more easily inserted into the first elastic segment 311.
[0064] For example, in some embodiments, the second elastic segment 312 is narrower in the width direction. After covering the second elastic segment 312 with an elastic covering layer 32, the elastic covering layer 32 can be covered at least in the width direction of the second elastic segment 312, so that it is consistent with the appearance size of the first elastic segment 311. This allows 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. Furthermore, when the first elastic segment 311 is also covered with an elastic covering layer 32, the overall appearance consistency of the ear portion 30 can be improved, allowing 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.
[0065] Please see Figure 4 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.
[0066] 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.
[0067] 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.
[0068] 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.
[0069] 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.
[0070] 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.
[0071] 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.
[0072] In some embodiments, the earphone 200 may further include a pressure sensor 41. A space for accommodating the pressure sensor 41 is provided within the first elastic segment 311. Further in some embodiments, the first elastic segment 311 is made of plastic.
[0073] The pressure sensor 41, also called a pressure sensor, allows users to interact with the headphones 100. In some embodiments, the pressure sensor 41 can be configured to generate corresponding electrical signals based on the user's touch actions on the headphones 100. That is, when the pressure sensor 41 is triggered, the headphones 100 can generate corresponding control commands to allow the headphones 100 to perform preset functions. In some scenarios, touch actions can include any single action or combination of multiple actions such as single click, double click, long press, and swipe; in some scenarios, control commands can be used to implement any single function or combination of multiple functions such as volume up / down, play / pause, next track, and power on / off. In some scenarios, when the user operates the headphones 100, for example, when the user presses the area on the headphones 100 where the pressure sensor 41 is located, the user can contact the pressure sensor 41 to generate an electrical signal, thereby generating corresponding control commands.
[0074] In some embodiments, the pressure sensor 41 can be configured to detect whether the user is wearing the headphones 100 and generate a corresponding electrical signal, thereby allowing the headphones 100 to perform preset functions, such as wear detection. In some scenarios, when the user wears the headphones 100, the pressure sensor 41 is triggered by the user's ear to generate an electrical signal, which in turn generates a corresponding control command.
[0075] It should be noted that the pressure sensor 41 can also perform other functions required by the headphones 200, which will not be elaborated here.
[0076] Please see Figure 7 , Figure 7 This is a schematic diagram of the structure of the elastic element 31 in some 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.
[0077] 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.
[0078] 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 .
[0079] 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 .
[0080] 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 .
[0081] 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 sub-elastic segment 3111 more difficult to deform than the second elastic segment 312, making it more suitable for attaching other structures. Furthermore, it makes the part of the ear portion 30 corresponding to the first sub-elastic segment 3111 more suitable for attaching other structures.
[0082] 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, and thus more suitable for attaching other structures. Furthermore, it makes the part of the ear portion 30 corresponding to the second sub-elastic segment 3112 more suitable for attaching other structures.
[0083] 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, making it more suitable for attaching other structures, and further making the part of the ear portion 30 corresponding to the first elastic segment 311 more suitable for attaching other structures.
[0084] 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.
[0085] 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.
[0086] 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.
[0087] 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.
[0088] Please see Figure 8 , Figure 8 This is a schematic diagram of the structure of the elastic element 31 in some 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.
[0089] 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.
[0090] In some embodiments, the distance between the two ends of the third sub-elastic segment 3121 is D31, and when the elastic element 31 switches from the natural state to the wearing state, 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 .
[0091] In some embodiments, the distance between the two ends of the fourth sub-elastic segment 3122 is D32, and when the elastic element 31 switches from the natural state to the wearing state, 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 .
[0092] 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 other structures, further making the part of the ear portion 30 corresponding to the first elastic segment 311 more suitable for attaching other structures.
[0093] 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 other structures, further making the part of the ear portion 30 corresponding to the first elastic segment 311 more suitable for attaching other structures.
[0094] 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 other structures, further making the part of the ear portion 30 corresponding to the first elastic segment 311 more suitable for attaching other structures.
[0095] 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.
[0096] 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.
[0097] 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.
[0098] 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.
[0099] Please see Figure 9 and Figure 10 , Figure 9 This is a schematic diagram of the structure of the elastic element 31 in some other embodiments. Figure 10 This is a schematic diagram of the structure of the elastic element 31 in some other embodiments. The first elastic segment 311 may be integrally formed with the second elastic segment 312. For example, the first elastic segment 311 and the second elastic segment 312 may have the same structure and / or material. In the manufacturing process of the elastic element 31, the first elastic segment 311 may be formed first, and the second elastic segment 312 may be formed by further processing at specific locations of the first elastic segment 311. For example, in Figure 9 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 10 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.
[0100] In some embodiments, the first elastic segment 311 and the second elastic segment 312 may be integrally formed from metal parts.
[0101] In some embodiments, the second elastic segment 312 is configured to be formed by partially opening or flattening a metal part.
[0102] In some embodiments, please refer to Figure 10 and Figure 11 , Figure 11 for Figure 9 The cross-sectional view of the elastic element 31 along line XI-XI in the embodiment shown. The first elastic segment 311 can be a tubular structure, for example... Figure 6 As shown, a partial cut is made on one side of the middle portion of the first elastic segment 311 to form an elongated through hole, so as... Figure 11 As shown, a second elastic segment 312 is thus formed. Because the partial removal alters the structure, the second elastic segment 312 is more prone to elastic deformation than the first elastic segment 311, resulting in a greater elastic deformation coefficient for the second elastic segment 312 than that for the first elastic segment 311. Furthermore, 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-section's outer contour is less than 0.6, thus making the second elastic segment 312 a sheet-like structure.

[0104] In some embodiments, please refer to Figure 12 and Figure 13 , Figure 12 This is a schematic diagram of the structure of the elastic element 31 in some other embodiments. Figure 13 for Figure 12 The cross-sectional view of the elastic element 31 along line XIII-XIII in the embodiment shown. The first elastic segment 311 can be a tubular structure, for example... Figure 6 As shown, the first elastic segment 311 is subjected to extrusion processing in the middle, so as... Figure 13 As shown, a second elastic segment 312 is formed. Because the extrusion process alters the structure, the second elastic segment 312 is more prone to elastic deformation than the first elastic segment 311, resulting in a greater elastic deformation coefficient for the second elastic segment 312 than that for the first elastic segment 311. Furthermore, 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, thus making the second elastic segment 312 a sheet-like structure.

The first elastic segment 311 may be a tubular structure, for example... Figure 6 As shown, compression is performed on both sides of the first elastic segment 311 to achieve the desired effect. Figure 13 As shown, a second elastic segment 312 is formed, such as a third sub-elastic segment 3121 and a fourth sub-elastic segment 3122. Because the extrusion process alters the structure, the second elastic segment 312, such as the third sub-elastic segment 3121 and the fourth sub-elastic segment 3122, is more prone to elastic deformation than the first elastic segment 311, resulting in a greater elastic deformation coefficient for the second elastic segment 312, such as the third sub-elastic segment 3121 and the fourth sub-elastic segment 3122 than that for the first elastic segment 311.

[0106] In some embodiments, please refer to Figure 2 The 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 part 10 and serve as part of the headphones 200. Of course, the sound-emitting part 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 part 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.
[0107] In some embodiments, please refer to Figure 3The 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, microphone 13, and pressure sensor 41. It is understood that the second housing assembly 21 and the battery 22 may form a contact portion 20 and serve as part of the earphone 200. Of course, the contact portion 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 contact portion 20 may also include a main board 23 disposed within the second housing assembly 21, which may be connected to the battery 22, speaker 12, microphone 13, pressure sensor 41, etc. In some embodiments, the main board 23 may be used to control the operation of the speaker 12. In some embodiments, the main board 23 may be used to control the operation of the microphone 13. In some embodiments, the main board 23 may cooperate with the pressure sensor 41 to enable human-computer interaction between the user and the earphone 200.
[0108] In some embodiments, please refer to Figure 5 and Figure 6 The first elastic segment 311 is tubular. The minimum outer diameter of the first elastic segment 311 can be R1. By adjusting the ratio of the maximum width N1 of the second elastic segment 312 to the minimum outer diameter R1 of the first elastic segment 311, the second elastic segment 312 becomes narrower in the width direction Y, which facilitates subsequent processing to form the ear 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 is consistent with that of the first elastic segment 311, so that the exposed part 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. Furthermore, when the first elastic segment 311 is also covered with an elastic covering layer 32, the overall appearance consistency of the ear portion 30 can be improved, so that the exposed part 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.
[0109] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 3 The earphone 200 may include a sound-emitting part 10, a contact part 20, and an ear-wrap part 30. The ear-wrap part 30 connects the sound-emitting part 10 and the contact part 20. When worn, the sound-emitting part 10 may be disposed within the concha cavity 102, the contact part 20 abuts against the back of the auricle, and the ear-wrap part 30 is wrapped around the outside of the helix 107 to provide clamping force for the sound-emitting part 10 and the contact part 20, so that the sound-emitting part 10 and the contact part 20 can cooperate to clamp each other, thereby clamping the entire earphone 200 in the ear 100.
[0110] In some embodiments, the elastic member 31 may be partially inserted into the sound-emitting part 10, such as the first housing assembly 11, to achieve the connection between the elastic member 31 and the sound-emitting part 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 abutting part 20, such as the second housing assembly 21, to achieve the connection between the elastic member 31 and the abutting part 20, such as the second housing assembly 21, and to improve the connection strength between the two.
[0111] 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 portion 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, 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.
[0112] Understandably, the first housing assembly 11 may also be configured in the same way as the second housing assembly 21, and may further include the housing body and the connecting housing.
[0113] Furthermore, in some embodiments, the elastic member 31 has an exposed portion relative to the sound-emitting part 10, such as the first housing assembly 11, and the abutting part 20, such as the second housing assembly 21, and provides clamping force to the sound-emitting part 10 and the abutting part 20 through the exposed portion. In a further technical solution, an elastic covering layer 32 covers this exposed portion.
[0114] In some embodiments, please refer to Figure 4 , Figure 4 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.
[0115] In some embodiments, please refer to Figure 7 , Figure 7The diagram shows an exposed portion of the elastic element 31 with a length of L11+L2+L12. For example, the first sub-elastic segment 3111 may have an exposed portion with a length of L11 relative to the first housing assembly 11 and the second housing assembly 21, and also with a length of L12 relative to the second elastic segment 312. Similarly, the second sub-elastic segment 312 may have an exposed portion with a length of L2 relative to both the first and second sub-elastic segments 3111 and 3112.
[0116] In some embodiments, the length ratio L11 / L2 of the exposed portion of the first sub-elastic segment 3111 to the exposed portion of the second elastic segment 312 is between 0.25 and 0.5, and the length ratio L12 / L2 of the exposed portion of the second sub-elastic segment 3112 to the exposed portion of the second elastic segment 312 is between 0.25 and 0.5, so as to connect the first housing assembly 11 and the second housing assembly 21 through the first sub-elastic segment 3111 and the second sub-elastic segment 3112, thereby improving the connection strength and connection stability.
[0117] In some embodiments, please refer to Figure 8 , Figure 8 The diagram shows an exposed portion of elastic member 31 with a length of L21+L1+L22. For example, a third sub-elastic segment 3121 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 L21. Similarly, a fourth sub-elastic segment 3122 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 L22. Likewise, the first elastic segment 311 may be exposed relative to the third sub-elastic segment 3121 and the fourth sub-elastic segment 3122, and may have an exposed portion of length L1.
[0118] In some embodiments, please refer to Figure 3 The earphone 200 may also include a wire 33, which may be part of the earpiece 30 and placed within the space formed by the elastic covering layer 32 or the elastic member 31, enabling connection between electronic devices in the first housing assembly 11 and electronic devices in the second housing assembly 21. For example, the wire 33 may connect the speaker 12 to the motherboard 23. For example, the wire 33 may connect the microphone 13 to the motherboard 23. For example, the wire 33 may connect the pressure sensor 41 to the motherboard 23.
[0119] In some embodiments, the wire 33 may be formed on the elastic member 31. In some embodiments, the wire 33 may pass through the first elastic segment 311 or through the second elastic segment 312. In some embodiments, the wire 33 may pass through the first sub-elastic segment 3111. In some embodiments, the wire 33 may pass through the second sub-elastic segment 3112. In some embodiments, the wire 33 may pass through the third sub-elastic segment 3121. In some embodiments, the wire 33 may pass through the fourth sub-elastic segment 3122. In some embodiments, the wire 33 may... Figure 5 The width direction Y or height direction Z of the second elastic segment 312 is set on one side or surface of, for example, the third sub-elastic segment 3121 or the fourth sub-elastic segment 3122.
[0120] In some further embodiments, the wire 33 passes through the first elastic segment 311, for example, a metal tubular body, and is disposed on one side of the second elastic segment 312, for example, a metal sheet, along the thickness or width direction of the second elastic segment 312, for example, a metal sheet.
[0121] In some further embodiments, the wire 33 passes through the first elastic segment 311, for example, a metal tubular body, and is disposed in the second elastic segment 312, for example, a metal sheet.
[0122] Please see Figure 15 , Figure 15 This is a partial circuit diagram of the earphone 200 in some embodiments of this application. The earphone 200 may include a radio frequency circuit 231 disposed on the motherboard 23, and may also include an antenna 34 disposed on the elastic member 31. The radio frequency signal output by the radio frequency circuit 231 is configured to be radiated through the antenna 34. In some embodiments, the antenna 34 may be disposed on the elastic member 31 or on the ear-wrap portion 30 corresponding to the elastic member 31.
[0123] The performance of antenna 34 is related to its specific structural form. By redistributing and / or concentrating the deformable parts of elastic member 31, antenna 34 can be attached to the less deformable parts of elastic member 31 or to the parts of ear 30 corresponding to the less deformable parts. This allows for the adjustment of the first elastic segment 311 and the second elastic segment 312, making the elastic deformation coefficient of the second elastic segment 312 greater than that of the first elastic segment 311, i.e., O3 > O2. This makes the first elastic segment 311 less deformable than the second elastic segment 312. When the antenna is placed in the first elastic segment 311 or at the part of ear 30 corresponding to the first elastic segment 311, the shape change of antenna 34 can be minimized or kept unchanged, thus maximizing the performance of antenna 34.
[0124] In some embodiments, please refer to Figure 4The first elastic segment 311 may have an exposed portion 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. Furthermore, this exposed portion may be more suitable for attaching the antenna 34 because it is not affected or is minimally affected by the first housing assembly 11 and the second housing assembly 21, or is not affected or is minimally affected by the electronic components within the first housing assembly 11 and the second housing assembly 21. In a further embodiment, the antenna 34 may be a flexible circuit board, plating, coating, or other structure, and is disposed within the ear-like portion 30.
[0125] In some embodiments, please refer to Figure 7 The first sub-elastic segment 3111 may have an exposed portion relative to the first housing assembly 11 and the second housing assembly 21, and exposed relative to the second elastic segment 312, and has an exposed portion of length L11, wherein an antenna 34 may be attached to the exposed portion.
[0126] In some embodiments, please refer to Figure 7 The second sub-elastic segment 3112 may have an exposed portion relative to the first housing assembly 11 and the second housing assembly 21, and an exposed portion with a length of L12, and an antenna 34 may be attached to the exposed portion.
[0127] In some embodiments, please refer to Figure 8 The first elastic segment 311 may have an exposed portion relative to the third sub-elastic segment 3121 and the fourth sub-elastic segment 3122, and may have an exposed portion of length L1, wherein an antenna 34 may be attached to the exposed portion.
