Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by a person skilled in the art without any inventive effort, are intended to be within the scope of the present application based on the embodiments of the present application.

The embodiment of the application provides an ear clip and an earphone with various use postures. For convenience of description, the ear clip and the earphone of the present application will be described below as applied to the ear of a human body.

Referring to fig. 1, fig. 1 is a schematic diagram of an ear 10 of a human body to which the ear clip and the earphone according to the embodiment of the application are applied. As shown in fig. 1, the ear 10 of the user may include an helix 11, a concha 12, an antitragus 13, a triangular fossa 14, a concha 15, an eardrum 16, a tragus 17, an earlobe 18, wherein the concha 15 may include a concha boat 151 and a concha cavity 152, and the eardrum 16 may also be referred to as an external concha or an opening of the external auditory canal. In addition, the "front side of the ear" in the present application is a concept of "front side of the ear" with respect to "rear side of the ear", which means a side of the ear 10 facing away from the head, and "rear side of the ear" which means a side of the ear 10 facing toward the head.

The ear clip 20 provided by the embodiment of the present application can provide a plurality of use attitudes, such as at least two use attitudes. Accordingly, the earphone 30 provided in the embodiment of the present application may implement multiple wearing states, such as at least two wearing states, by using the ear clip 20. In the description of the present application, the meaning of "a plurality" is two or more, unless explicitly defined otherwise. The "wearing state" of the present application refers to a stable wearing state when the earphone 30 is stably worn on the ear 10 of the human body. Of course, there may be some difference in the actual wearing state of the headphones 30 due to individual differences among users.

Referring to fig. 2, an earphone 30 according to an embodiment of the present application includes a front ear module 31, a balancing module 32, and an ear clip 20, where the ear clip 20 connects the front ear module 31 and the balancing module 32.

Referring to fig. 3 to 5, the earphone 30 according to the embodiment of the present application simulates the wearing state of the ear 10 worn on the human body. In the first wearing state (see fig. 3), the pre-ear module 31 is located on the front side of the ear 10, the balancing module 32 is located on the rear side of the ear 10 (see fig. 5), and the pre-ear module 31 and the balancing module 32 clamp the ear 10 via the ear clip 20. In the second wearing state (see fig. 4), the position of the pre-aural module 31 is changed by the ear clip 20, and the balancing module 32 may be located at the rear side of the ear 10 or at the edge of the helix 11. The so-called "change of position" may be: the entire or a part of the surface of the pre-aural module 31 or a part of the structure thereof is moved toward the ear hole 16 of the ear 10, and the pre-aural module 31 covers at least a part of the area of the ear hole 16. Specific variations are described further below.

The structure of the ear clip 20 and various usage postures thereof according to the embodiment of the present application will be described in detail using various embodiments, and then the detailed structure of the earphone 30 and various wearing states thereof according to the embodiment of the present application will be described.

Referring to fig. 6 and 7, a schematic structural diagram of an ear clip 20 according to a first embodiment of the present application is shown in fig. 6, wherein fig. 6 shows a first usage posture of the ear clip 20, and fig. 7 shows a second usage posture of the ear clip 20. The ear clip 20 provided in the first embodiment of the present application includes a main body portion 21 and at least one deforming member 22; the body portion 21 has a first end 201 and a second end 202, and the deforming member 22 is disposed in the body portion 21 near the first end 201. The deforming member 22 has a first folded shape (see fig. 8) and a second folded shape (see fig. 9) corresponding to the first use posture (see fig. 6) and the second use posture (see fig. 7) of the ear clip 20, respectively. Specifically, in the first use posture, the deforming member 22 is bent to form a first bent shape facing the ear portion 10, and the first end portion 201 is located at a first position on the front side of the ear portion 10; in the second use posture, the deforming member 22 is bent back to the ear portion 10 to form a second bent shape, and the first end 201 is located at a second position on the front side of the ear portion 10; wherein the first and second folded shapes of the deforming member 22 may be the same or different, and the first and second positions of the first end 201 are different.

The ear clip 20 provided in the embodiment of the present application is provided with the deforming member 22, where the deforming member 22 is configured to form at least two bending shapes, and the position of the first end 201 at the ear 10 can be adjusted, so that the ear clip 20 has at least two use positions. Furthermore, the present application can make the earphone 30 have various wearing states by adjusting the shape of the ear clip 22 and changing the use posture of the ear clip 22, thereby solving the problem of single use posture of the existing earphone.

It should be noted that, the above-mentioned "the first position and the second position of the first end 201 are different" may be understood as follows: the position of the first end 201 relative to the ear 10 changes due to the change in the relative positions of the first end 201 and the second end 202. One of the cases where the relative positions of the first end 201 and the second end 202 are changed may be embodied in: the distance between the first end 201 and the second end 202 is changed. For example, in a first use posture, the first end 201 and the second end 202 have a first distance 203, as shown in fig. 6; in the second use position, the first end 201 and the second end 202 have a second distance 204, as shown in fig. 7; wherein the second distance 204 is greater than the first distance 203. Thus, when the ear clip 20 is switched from the first use posture to the second use posture, the first end 201 moves in a direction away from the second end 202.

However, the relative position change of the first end 201 and the second end 202 is not limited to the case of the above-described distance change, but may be such that the distance between the two is unchanged but the orientation is changed so that the relative position of the two is changed, or such that the distance and the orientation between the two are both changed so that the relative position of the two is changed.

The above-mentioned so-called "first and second folded shapes of the deformation 22 may be identical" may be understood as: the deforming members 22 have the same or symmetrical shape and the same geometric dimensions (e.g., length, width, chord cut angle, average radius of curvature, etc.) although they have different bending directions. It should be noted that the same references mentioned in the embodiments of the present application refer to: identical or substantially identical. For example, referring to fig. 8 and 9, the deforming member 22 is bent in opposite directions to form an arc shape with opposite opening directions. In other words, in the embodiment shown in fig. 8 and 9, the first and second folded shapes are each arc-shaped, and the length, width, chord cut angle, average radius of curvature, etc. thereof are all substantially the same, so that they are substantially the same or symmetrical. However, the first bending shape and the second bending shape are not limited to an arc shape, and the arc shape is only a special curve shape, and may be other geometric curves, free curves, or a combination of curves and straight lines, etc. that can realize at least two identical bending shapes.

The above-mentioned so-called "first and second folded shapes of the deformation 22 may be different" may be understood as: the deforming member 22 may have a different or slightly different shape after bending, or at least one of a different or slightly different geometric dimension (e.g., length, width, chord cut angle, average radius of curvature, etc.). Illustrating several cases where the "first and second folded shapes may be different": both profiles are generally arcuate with different average radii of curvature, or both profiles are significantly different curvilinear shapes with the same or different average radii of curvature. Likewise, the first and second folded shapes herein may be geometric curves, free curves, or a combination of curves and straight lines, etc. that enable at least two different folded shapes.

The ear clip 20 according to the first embodiment of the present application is further provided with a semi-enclosed holding space 23, as shown in fig. 6 and 7. The clamping space 23 can provide a receiving space for the ear 10 when the ear clip 20 clamps the ear 10. When the deforming member 22 is bent towards the clamping space 23, the deforming member 22 will form a first bent shape, and when the deforming member 22 is bent away from the clamping space 23, the deforming member 22 will form a second bent shape.

The detailed structure of the ear clip 20 provided in the first embodiment of the present application will be described in detail below.

Referring to fig. 6 and fig. 7 again, the main body 21 according to the first embodiment of the present application is curved along the length direction L1, and the curved design is to keep the main body 21 elastic, so as to realize elastic opening and closing of the ear clip 20, thereby ensuring that the ear clip 20 can be clipped or hung on the ear 10. Furthermore, by a curved design, the body part 21 is curved around the clamping space 23 forming the ear clip 20.

Further, the body portion 21 has a first average radius of curvature proximate the first end portion 201; the body portion 21 has a second average radius of curvature proximate the second end 202; in different embodiments, the first average curvature radius and the second average curvature radius may be set according to actual requirements, and may also be adjusted according to different use postures. For example, in one embodiment, in a first use configuration, the first and second average radii of curvature may be set to be substantially the same such that the first and second ends 201, 202 may be symmetrically clamped to the front and rear sides of the ear 10. And in a second use position, the first average radius of curvature may be greater than the second average radius of curvature. By configuring the body portion 21 such that the curvature is substantially greater proximate to the second end portion 202 than proximate to the first end portion 201, the second end portion 202 can be enabled to provide a greater sense of adhesion or fit or grip to the rear side of the ear 10, thereby alleviating the sense of compression of the first end portion 201 to the front side of the ear 10. Of course, in other embodiments, in order to meet the requirements of other functions or other usage scenarios set forth by the user, in the first usage posture and the second usage posture, the first average radius of curvature and the second average radius of curvature of the main body 21 may also be selected to be different from those described above.

In the embodiment of the present application, the value ranges of the first average radius of curvature and the second average radius of curvature may be set as follows: in the first use posture, the first average curvature radius is 10 mm-40 mm, and the second average curvature radius is 3 mm-10 mm; in the second use posture, the first average curvature radius is 10 mm-40 mm; the second average radius of curvature is 3mm to 10mm. The specific values may be selected based on the fit between the ear clip 20 and the ear 10 to further optimize the comfort and stability of wear, without limitation.

The main body 21 provided by the embodiment of the application is made of soft materials, and the soft materials not only can change the shape adaptively according to different use postures, but also can realize skin-friendly effect. The soft material may have the characteristic of an elastic material, so that the adhesion between the ear clip 20 and the ear 10 can be enhanced, and the wearing is more stable. The soft material can also have the characteristic of ultra-light material, so that the wearing of a user is easier and more comfortable. Of course, the so-called soft material may be flexible, ultra-light, and the like, thereby providing further advantages to the ear clip 20.

In the first use posture, as shown in fig. 6, the main body 21 has a substantially C-shape or U-shape, the first end 201 is located on the front side of the ear 10, and the second end 202 is located on the rear side of the ear 10. Since the main body 21 is arched to fit the shape of the auricle 11 of the ear 10 and is attached to the ear 10, the first end 201 and the second end 202 can be closed and opened and closed elastically, thereby forming a clamping shape for the ear 10. In the second use posture, as shown in fig. 7, the main body 21 is L-shaped or hook-shaped, the first end 201 is located on the front side of the ear 10, and the second end 202 is located on the rear side of the ear 10, or may be located at the edge of the helix 11. That is, in the second use posture, the position of the second end 202 may be changed appropriately according to the change of the position of the first end 201, so that the balance module 32 of the earphone 30 can be ensured to be hung on the ear 10, or only the earphone 30 can be integrally hung on the ear 10 or clamped to the ear 10. A detailed description will be given later on of the balancing module 32.

Referring to fig. 8, 9 and 10, the deformation member 22 according to the first embodiment of the present application is a flexible sheet, for example, a metal sheet, or other flexible sheet except a metal sheet, or other deformable sheet except a flexible sheet. More specifically, in the embodiment of the present application, the deformation member 22 may be a metal spring or a spring made of a nitinol material, which is not only capable of bending and deformation, but also may be configured as an antenna of the earphone 30. The deformation member 22 provided by the embodiment of the application can be bent into various bending shapes along different directions. For example, it may be bent in opposite directions into two substantially symmetrical shapes (a first bent shape and a second bent shape). In practice, the so-called different directions cannot be limited only to the opposite directions, and the plurality of bent shapes cannot be limited only to the first bent shape shown in fig. 8 and the second bent shape shown in fig. 9. In other embodiments, deformation member 22 may be configured to bend at other angles, thereby being capable of being bent into more bent shapes, further providing a greater variety of use configurations for ear clip 20. Therefore, the deformation member 22 provided in the embodiment of the present application is a flexible sheet, and can be freely designed to form different shapes after being deformed according to different bending modes or deformation modes, so as to provide more use postures.

Referring to fig. 11, the surface of the deforming member 22 according to the first embodiment of the present application is configured as an arc surface, the arc surface projects as an arc 220 on a side projection plane, and a chord angle a of the arc 220 is 15 degrees to 45 degrees. In the first use posture and the second use posture, the chord cut angles a may be the same (may be substantially the same), or may be different (e.g., slightly different or greatly different). Specifically, as shown in fig. 8 and 9, the first bending shape of the deforming member 22 and the second bending shape of the deforming member 22 are provided in the opposite directions, for example, the opening of the first bending shape of the deforming member 22 faces the holding space 23 of the ear clip 20, and the opening of the second bending shape of the deforming member 22 faces away from the holding space 23 of the ear clip 20. However, in the first bending shape and the second bending shape, the surface of the deforming member 22 can be projected as a section of arc 220 on the side projection surface, and the chord angle a of the corresponding arc 220 of the two bending shapes can be the same or different. In the first embodiment of the present application shown in fig. 8 and 9, the chord angle a of the corresponding arc 220 formed by the projection of the first and second folded shapes of the deforming member 22 on the side projection surface is the same.

The "arc" may be an inner arc formed on the side projection surface of the deformable member 22 or an outer arc formed on the side projection surface of the deformable member 22. In general, the projection of the deformation 22 onto the side projection surface does form an inner arc and an outer arc, but since the deformation 22 provided in the embodiment of the present application is a sheet, the inner arc and the outer arc have substantially the same chord tangent angle, the inner arc and the outer arc need not be distinguished, and are collectively referred to as "arcs" herein. In other embodiments, however, if deformation 22 is not a sheet and is thick enough to cause the chord cut angles of the inner and outer arcs to differ, then chord cut angle A (15 degrees to 45 degrees) of arc 220 may be referred to as the chord cut angle of the outer arc.

The deforming member 22 provided in the embodiment of the present application may be laid in the entire main body 21 along the longitudinal direction L1 of the main body 21, or may be laid in a part of the main body 21. Specifically, the length of the deformation member 22 provided by the embodiment of the present application is at least one fifth of the length of the main body 21, so that when the deformation member 22 is switched between the first folded shape and the second folded shape, a significant change in the position of the first end 201 is caused, thereby bringing about various use postures of the ear clip 20. In other words, if the length of the deforming member 22 is too small, when the deforming member 22 is switched from the first folded shape to the second folded shape, it is difficult to cause a significant change in the position of the first end 201, and thus it is also difficult to achieve switching of the use posture of the ear clip 20.

Referring to fig. 6 and 7, the first embodiment of the present application provides a deforming member 22 having a length substantially half of the length of the main body 21, so as to sufficiently change the position of the first end 201 relative to the second end 202, thereby providing at least two use positions for the ear clip 20. Of course, in other embodiments, the length of the deforming member 22 may also be equal to the length of the main body portion 21.

Referring to fig. 6 and 7, a deforming member 22 according to a first embodiment of the present application is configured to be disposed in a main body 21. Specifically, the deforming member 22 is embedded or buried in the main body portion 21 by an injection molding process, so that the main body portion 21 can change its posture as the shape of the deforming member 22 changes.

In other embodiments, the deforming member 22 may be disposed in the main body portion 21 without being limited to an injection molding process, for example: referring to fig. 12, a cavity 210 may be provided in the main body 21, the cavity 210 being provided along the longitudinal direction L1 of the main body 21, and the deforming member 22 being accommodated in the cavity 210. Even the length dimension of the cavity 210 may be designed to be larger than the length dimension of the deforming member 22, so that the deforming member 22 can slide along the length direction L1 of the main body 21, thereby changing the shape of more areas on the ear clip 20 and bringing more use positions to the ear clip 20.

In detail, the deforming member 22 may slide and stay at an arbitrary position in the cavity 210. In each resting position, the deformation member 22 can be bent towards different directions to form at least two bending states as shown in fig. 8 and 9, and the main body 21 follows the deformation member 22 to deform, so that the ear clip 20 has at least two use postures. Then, if the deforming member 22 is capable of resting in two different positions, the ear clip 20 can assume at least four positions of use; if the deforming member 22 is capable of resting in three different positions, the ear clip 20 may assume at least six positions of use; by analogy, more use gestures can be obtained. It should be noted that the term "different positions" refers to two different positions having a large distance therebetween, or to different positions that are sufficient to cause the main body portion 21 to change. For example, if the position interval between the two stops is small, the position change after the deforming member 22 slides is less obvious, and it is difficult to cause the change of the main body 21, so that the use posture of the ear clip 20 cannot be increased. Thus, as long as the distance between the positions where the deforming member 22 stays each time is large, the deforming member 22 basically increases at least two usage orientations again for the ear clip 20. Or so, as long as the position where the deforming member 22 stays each time is sufficient to cause a change in the main body portion 21, the deforming member 22 basically adds at least two more use attitudes to the ear clip 20. It can be seen that deforming member 22 is slidably disposed within cavity 210, which can provide a greater variety of use attitudes for ear clip 20.

In the embodiment of the present application, not only the deforming member 22 is provided with two bending shapes, but also a rotating shaft structure (not shown) may be provided at one end of the deforming member 22, and the position of the deforming member 22 in the main body 21 is changed by the rotating shaft structure, so that the shape of the main body 21 is changed, and more various use postures can be added to the ear clip 20.

In addition, a supporting structure (not shown) may be further disposed in the main body 21 according to the embodiment of the present application, so as to increase the structural strength of the main body 21. The support structure may be a metal sheet, a metal wire, a titanium wire, or the like, and is provided in the entire main body portion 21 or at a partial position of the main body portion 21, which can play a role of supporting the main body portion 21 and improving the elasticity of the main body portion 21.

Although the embodiment of the present application only shows one deforming member 22 in the drawings, the ear clip 20 is not limited to the configuration of one deforming member 22, but may include two deforming members 22. For example, by arranging two deforming members 22 along the longitudinal direction of the main body portion 21, the deformed region can be enlarged, adding more use posture to the ear clip 20. For example, the ear clip 20 can have at least two positions of use when one of the deforming members 22 is deformed; when the other deforming member 22 deforms, the ear clip 20 will increase in at least two use positions; the ear clip 20 can have at least four positions of use at this time. When two deforming members 22 are provided in other embodiments of the present application, the two deforming members 22 may be disposed independently and at intervals in the main body 21, and the respective deforming members may not be associated with each other when bending changes. Of course, the two deforming members 22 may be fixedly connected or movably connected to be disposed in the main body 21. In addition, when two deforming pieces 22 are arranged in the main body portion 21, the two deforming pieces 22 may have the same structure or may have different structures. In the body part 21, the two deformation elements 22 may also be arranged symmetrically or in other patterns.

Referring to fig. 8 and 9, the deformation member 22 according to the first embodiment of the present application is a flexible sheet, and the deformation member 22 includes a first flexible arm 221, a second flexible arm 222 and an opening 223; the first flexible arm 221 and the second flexible arm 222 are spaced around the aperture 223. When the deforming member 22 is provided in the main body 21, the longitudinal direction L2 of the deforming member 22 and the longitudinal direction L1 of the main body 21 are substantially identical, and the width direction W2 of the deforming member 22 and the width direction W1 of the main body 21 are substantially identical. The first flexible arms 221 and the second flexible arms 222 of the deforming member 22 are arranged and spaced apart along the width direction W2 of the deforming member 22. The openings 223 can reduce the weight, improve the adhesion degree of the deformation member 22 and the main body 21, and disperse the external force to avoid the undesired reverse rotation of the deformation member 22, for example, avoid the reverse bending of the deformation member 22 when the deformation member 22 is touched by a bit accidentally.

When the deforming member 22 is in the first folded shape as shown in fig. 8, the arc-shaped opening of the deforming member 22 faces the holding space 23 of the ear clip 20 (see fig. 6). When the deforming member 22 is in the second folded shape as shown in fig. 9, the arc-shaped opening of the deforming member 22 faces away from the holding space 23 of the ear clip 20 (see fig. 7). As can be seen from the above, in the present embodiment, the aforementioned "the deforming member 22 is bent to form the first bending shape" toward the ear portion 10 means that: the deforming member 22 is bent to form a first bent shape facing the holding space 23; and "the deforming member 22 is bent back to the ear portion 10 to form a second bent shape" means that: the deformation member 22 is bent back to the clamping space 23 to form a second bent shape.

In the first embodiment, the first flexible arm 221 and the second flexible arm 222 are substantially identical in length, and substantially identical in width and curvature, so that the first and second folded shapes of the deforming member 22 are substantially identical. For example, the deformation 22 has a curved first and a curved second shape, and the average radius of curvature ranges from 10mm to 30mm. In the first embodiment, since the first flexible arm 221 and the second flexible arm 222 have substantially the same size, when the deforming member 22 is deformed into the first bent shape and the second bent shape, the stresses on the first flexible arm 221 and the second flexible arm 222 can cancel each other without the occurrence of the situation that the stresses of the two flexible arms 221, 222 are different, so that a stable bent shape can be provided. Of course, in other embodiments, the user may put forth different use posture requirements according to different application scenarios, and at this time, the first flexible arm 221 and the second flexible arm 222 may adopt different lengths, different widths, or different radians, so that the bending directions of the first flexible arm 221 and the second flexible arm 222 are changed, and the radians are changed, so that at least two use postures different from the present embodiment can be provided.

Referring to fig. 8 and 9, the deforming member 22 according to the first embodiment of the present application further includes a first connecting portion 224 for fixedly connecting one ends of the first flexible arm 221 and the second flexible arm 222. The term "fixed connection" is used with respect to the term "movable connection". The fixed connection in the first embodiment of the present application refers to a one-piece structure, such as: the first connecting portion 224 is a one-piece structure with the first flexible arm 221 and the second flexible arm 222, rather than a two-piece structure connected together. In other embodiments, the fixed connection may also be another way of connection, such as by welding.

Referring to fig. 8 and 9, the deforming member 22 according to the first embodiment of the present application further includes a second connecting portion 225 for movably connecting the other ends of the first flexible arm 221 and the second flexible arm 222, and a movable gap is formed between the first flexible arm 221 and the second flexible arm 222 at the second connecting portion 225. In the first embodiment of the present application, the second connecting portion 225 movably connects the first flexible arm 221 and the second flexible arm 222 by means of a movable riveting, so as to form a movable gap. According to the deformation piece 22 provided by the first embodiment of the application, the movable gap is arranged at the riveting position, so that certain elastic potential energy can be stored for the two flexible arms 221 and 222, the two flexible arms 221 and 222 can maintain the deformation state, and the deformation piece 22 cannot be overturned when no external force acts, so that two stable bending shapes are obtained.

The first connecting portion 224 provided in the first embodiment of the present application has a larger area than the second connecting portion 225, so that the deformation element 22 forms a contracted shape at the second connecting portion 225, which is favorable for forming a movable connection at the second connecting portion 225 and for performing bending operation on the deformation element 22 near the second connecting portion 225, thereby obtaining a stable bending state. In addition, since bending of the deforming member 22 is generally easily achieved by applying a bending force to the deforming member 22 near the second connecting portion 225, when the deforming member 22 is disposed on the main body portion 21, the first connecting portion 224 is disposed near the first end portion 201 and the second connecting portion 225 is disposed away from the first end portion 201, so that the user does not need to operate the first connecting portion 224 near the first end portion 201 and only needs to bend the deforming member 22 at the second connecting portion 225 spaced away from the first end portion 201, thereby obtaining a larger operation space for the user.

Referring to fig. 13, the deforming member 22 according to the first embodiment of the present application may further include other modifications, for example, the deforming member 22 includes a fixing connector 226, and the fixing connector 226 is disposed on the first connecting portion 224 and protrudes toward the first end 201 of the main body 21 for fixedly or electrically connecting with the earphone 30. For example, the fixed connector 226 may be mechanically or electrically connected to the front ear module 31 of the headset 30, and in particular may be connected to wiring in the front ear module 31.

The ear clip and the deforming member provided by the second embodiment of the present application will be described below. The ear clip according to the second embodiment of the present application is denoted by reference numeral 20a, the main body portion by reference numeral 21a, and the deforming member by reference numeral 22 a. That is, the elements or structures in the second embodiment of the present application share the same reference numerals and are additionally added with the suffix a as similar elements or similar structures in the first embodiment shown in fig. 6 to 13.

Referring to fig. 14 to 16, a structural schematic diagram of a deformation member 22a according to a second embodiment of the present application is shown in fig. 14, wherein fig. 14 shows a first bent shape of the deformation member 22a, fig. 15 shows a second bent shape of the deformation member 22a, and fig. 16 shows a comparative schematic diagram of the deformation member 22a in the first bent shape and the second bent shape. As shown in fig. 14 and 15, the deformation member 22a provided in the second embodiment of the present application is a flexible sheet, and includes a first flexible arm 221a, a second flexible arm 222a, and an opening 223a; the first flexible arm 221a and the second flexible arm 222a are spaced around the aperture 223 a. The deforming member 22a further includes a first connecting portion 224a for fixedly connecting one ends of the first flexible arm 221a and the second flexible arm 222 a. The deforming member 22a includes a second connecting portion 225a for fixedly connecting the other ends of the first flexible arm 221a and the second flexible arm 222 a.

The deformation member 22a provided by the second embodiment of the present application is mainly different from the deformation member 22 provided by the first embodiment of the present application described above in that: the second connecting portion 225a of the deforming member 22a according to the second embodiment of the present application is used to fixedly connect (non-movably connect) the other ends of the first flexible arm 221a and the second flexible arm 222 a.

Therefore, in the deformation member 22a provided in the second embodiment of the present application, the first flexible arm 221a, the second flexible arm 222a, the first connecting portion 224a and the second connecting portion 225a may be a one-piece structure, and the whole deformation member 22a is directly punched through the punching process, and no other process is required to be performed. Of course, in other embodiments, the deformation element 22a provided in the second embodiment of the present application may also realize that the first connecting portion 224a is fixedly connected to one end of the first flexible arm 221a and the second flexible arm 222a, and the second connecting portion 225a is fixedly connected to the other end of the first flexible arm 221a and the second flexible arm 222a by other fixing connection means.

In addition, in the deforming member 22a provided in the second embodiment of the present application, the middle width of the opening 223a is larger than the both end widths of the opening 223 a. With this configuration, it is possible to provide the first flexible arm 221a and the second flexible arm 222a with sufficient deformation space, preventing the two from interfering during deformation or bending.

Except for the above differences, the structural details and design parameters of the deforming member 22a provided by the second embodiment of the present application can be selectively configured with reference to the deforming member 22 provided by the first embodiment of the present application described above. That is, the design requirements set forth above for the deforming member 22 provided in the first embodiment of the present application are equally applicable to the deforming member 22a provided in the second embodiment of the present application. For example, the chord angle a, the average curvature radius, the supporting structure, the fixing joint 226, the fixing manner of the fixing joint and the main body 21, the length ratio of the fixing joint and the main body 21, the material, the number and other configuration requirements of the deformation member 22 according to the first embodiment of the present application can be applied to the deformation member 22a according to the second embodiment of the present application.

Referring to fig. 17 and 18, the ear clip 20a according to the second embodiment of the present application can generate two usage postures according to the two bending shapes of the deformation member 22a, wherein fig. 17 is a first usage posture of the ear clip 20a according to the second embodiment of the present application, and fig. 18 is a second usage posture of the ear clip 20a according to the second embodiment of the present application.

Likewise, the design requirements set forth above for the ear clip 20 and the main body portion 21 thereof provided in the first embodiment of the present application are equally applicable to the ear clip 20a and the main body portion 21a thereof provided in the second embodiment of the present application. For example, the configuration requirements of the first average radius of curvature, the second average radius of curvature, the shape, the material, etc. of the main body 21 according to the first embodiment of the present application can be applied to the main body 21a according to the second embodiment of the present application.

Referring to fig. 19 to 22, a schematic structural diagram of an earphone 30 is provided according to an embodiment of the present application, in which fig. 19 and 20 show a variation of a deforming member 22 of a first embodiment in an ear clip 20 through a partial sectional view, and fig. 21 and 22 show a variation of a deforming member 22a of a second embodiment in an ear clip 20a through a partial sectional view.

Referring to fig. 19, the earphone 30 provided by the embodiment of the present application includes a front ear module 31, a balancing module 32 and an ear clip 20, wherein the ear clip 20 is connected to the front ear module 31 and the balancing module 32, and the ear clip 20 has multiple use postures, so that the earphone 30 provided by the embodiment of the present application has multiple wearing states. The specific structure of the ear clip 20 may be described with reference to the structure of the ear clip 20 provided in the above embodiments of the present application.

In an embodiment of the application, the pre-ear module 31 is connected to the first end 201; the balancing module 32 is connected to the second end 202. The connection may be a rotational connection, so that the front ear module 31 and the balance module 32 may be adjusted in time by rotation in different wearing states, so that not only an ergonomic comfort state but also a stable state in which the headset 30 is hung on the ear 10 can be achieved. Of course, in other embodiments, the rotational connection herein may be changed to a fixed connection to meet the requirements of a particular use environment.

In the first wearing state of the earphone 30, as shown in fig. 3 and 5, the front ear module 31 is located at the front side of the ear 10, the balance module 32 is located at the rear side of the ear 10, the front ear module 31 and the balance module 32 clamp the ear 10 via the ear clip 20, and the ear clip 20 is in the first use posture as shown in fig. 19 or 21.

In the second wearing state of the headset 30 shown in fig. 4, the ear clip 20 is switched from the first use posture to the second use posture, and as shown in fig. 20 or fig. 22, the position of the front ear module 31 is changed under the driving of the ear clip 20, so that a different functional mode, such as a change in sound quality or volume, is realized.

According to the earphone 30 provided by the application, the ear clips 20 with various use postures are arranged to form various wearing states, so that the wearing mode can be adjusted according to the user demands, and the use experience of the user is effectively improved. For example, the earphone 30 with various wearing states can adapt to ears with different shapes and sizes of users, and the users can adjust the positions of the ear clips 20 at any time to change the use postures, so that higher quality and more excellent listening experience can be brought to the users.

The change in the position of the pre-ear module 31 and the balance module 32 in the first wearing state and the second wearing state will be specifically described below.

In the embodiment of the present application, the pre-aural module 31 is a sound generating device. The pre-ear module 31 is provided with a connection face 310 and a contact face 311 (see fig. 19 for reference), the connection face 310 being intended to be connected to the first end 201 of the ear clip 20. As shown in fig. 3, in the first wearing state, the contact surface 311 is abutted against the front side of the ear 10 and contacts the ear 10. For example, the contact surface 311 may rest in whole or in part against the concha cavity 152 of the ear 10, or may rest against the antitragus 13 (see fig. 1 for indicia) of the ear 10 or other region on the anterior side of the ear 10. At this time, one of the surfaces of the balancing module 32 also abuts against the rear side of the ear 10. The pre-ear module 31 and the balance module 32 clamp the ear 10 by the clamping force provided by the ear clamp 20, thereby providing a stable wearing state for the earphone 30.

When the user switches the ear clip 20 from the first use posture to the second use posture, the contact surface 311 moves toward the direction approaching the earhole 16 of the ear 10, and the front ear module 31 covers at least a part of the earhole 16 area, as shown in fig. 4. At this point, the headset 30 is in a second wearing state, in which the balancing module 32 may still be located at the rear side of the ear 10 or moved from the rear side of the ear 10 to the edge near the helix 11. When the balancing module 32 is located on the rear side of the ear 10, the pre-ear module 31 and the balancing module 32 can still clamp the ear 10 with the clamping force provided by the ear clamp 20. When the balancing module 32 is moved to the rim of the helix 11, one of the surfaces of the balancing module 32 may still rest against the ear 10, thereby gripping the ear 10 in conjunction with the pre-aural module 31. Of course, when the balancing module 32 moves to the rim of the helix 11, the balancing module 32 may not be in surface contact with the back side of the ear 10 due to the difference in shape of the ear 10 of the user, but rather hang at the rim of the helix 11 and in line contact with the ear 10, and may even be suspended entirely from contact with the rim of the ear 10, in which case the headset 30 is worn on the ear 10 primarily by the combined action of the support force provided by the ear 10 to the front ear module 31 and the clamping force between the ear clip 20 and the balancing module 32 and the front ear module 31.

Furthermore, as before, embodiments of the present application provide an earclip 20 having a first average radius of curvature proximate to the first end 201 that is greater than a second average radius of curvature proximate to the second end 202; that is, the curvature of the ear clip 20 near the second end 202 is significantly greater than the curvature near the first end 201. By this configuration, the balancing module 32 connected to the second end 202 can be made to provide a greater clamping force for the headset 30. It should be noted in the specific implementation that if the thickness of the balancing module 32 is increased, then the curvature near the second end 202 may be suitably reduced. Conversely, if the thickness of the balancing module 32 is reduced, the curvature proximate the second end 202 may be suitably increased.

The earphone 30 provided by the embodiment of the application further comprises a battery and a main board. The battery may be disposed in the pre-ear module 31 or the balance module 32, and the main board may be disposed in the pre-ear module 31 or the balance module 32. Of course, the headset 30 may also include other structures, such as, but not limited to, a bluetooth antenna module, a USB charging module, etc., which are not limited in this embodiment of the present application.

In addition, in the present embodiment, the front ear module 31 is provided with a sound emitting surface 312 in addition to the connection surface 310 and the contact surface 311, as shown in fig. 19. The connection surface 310, the contact surface 311 and the sound outlet surface 312 may be in a smooth transition connection, for example, in a circular arc transition connection, so as to improve wearing comfort of the earphone 30. In this embodiment, the area of the sound emitting surface 312 is smaller than that of the contact surface 311, and the smaller sound emitting surface 312 can be easily extended to the ear hole 16 to form an in-ear shape, as shown in fig. 4. Even further, the smaller sound emitting surface 312 may be in contact with the area near the ear hole 16, so that the ear 10 can support the earphone 30 even further. In addition, it should be noted that the contact surface 311 and the sound emitting surface 312 are not limited to two different surfaces in the embodiment of the present application. That is, the contact surface 311 and the sound emitting surface 312 provided in the embodiment of the present application may be two different surfaces, or may be two different areas on the same surface, or may be the same area on the same surface, as long as the contact surface 311 in the embodiment of the present application can be used to contact an ear, and the sound emitting surface 312 can be used to emit sound.

The pre-aural module 31 provided by the embodiment of the application is a sound generating device, the sound generating device is provided with a sound outlet hole, the sound outlet hole is arranged on the sound outlet surface 312, and the sound outlet hole can be aligned with the ear hole 16. In addition, the outer surfaces of the front ear module 31 and the balance module 32 provided by the embodiment of the application can be made of elastic materials so as to increase the adhesion between the front ear module and the ear 10, and the wearing is more comfortable and stable.

The shape and size of the pre-aural module 31, the balance module 32 and other components or structures shown in the drawings of the present application are not intended to reflect the true proportions thereof, but are intended only to facilitate the description of embodiments of the present application.
