Description

TECHNICAL FIELD

[0001] The present application relates to the field of acoustics, in particular to an earphone and a pair of earphones. BACKGROUND

[0002] With the increasing popularity of electronic terminal technology and products, earphones have become a standard product in people's daily life, which can be used with electronic devices such as mobile phones and computers. The use of earphones gradually enters more daily life and work scenarios, providing users with convenient listening while also bringing various auditory enjoyment to users.

[0003] According to different wearing methods, earphones can be divided into in-ear, semi-in-ear, and head-mounted types. In-ear and semi-in-ear earphones need to be inserted into the ear canal for use, but this type of earphone is worn and supported by being inserted into the ear canal. The disadvantage is that long-term wearing can cause ear fatigue or discomfort, and some users may feel uncomfortable. Moreover, the sound emitting principle of this type of earphone directly enters the ear canal, which has a potential risk of damaging hearing if worn for a long time. Head-mounted earphones need to cover the pinna, which will cause a sense of oppression to the ear. Currently, the wearing method of ear clip earphones is to clip two earphone bodies on the pinna. Since this type of earphone does not need to be inserted into the ear canal or cover the pinna, it has gradually entered the field of view of consumers.

[0004] However, the common ear clip earphones on the market generally have poor call quality, which limits the application scenarios of ear clip earphones. For example, drivers need to make calls while driving, delivery personnel or couriers need to answer customer calls while riding, and business people need to make phone calls and operate computers at the same time during office work. Poor call quality will greatly affect the other things that users do simultaneously during phone calls, and the experience will be greatly reduced. SUMMARY

[0082] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application, for example, the terms "length", "width", "upper", "lower", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, refer to the orientation or position shown in the drawings and are used for convenience in describing the present application and are not intended to be limiting.

[0083] The terms "include", "has", "having" and any variations thereof in the specification and claims of the present application and above description of the drawings are intended to cover the inclusion not the exclusion of any elements or integers; the terms "first", "second", and the like in the specification and claims of the present application and above description of the drawings are used to distinguish between similar objects and are not necessarily used to describe a particular sequential order.

[0084] In the specification and claims of the present application and above description of the drawings, when an element or layer is referred to as being "on", "connected to", "mounted to", or "connected with" another element or layer, it can be directly on, connected, mounted, or connected with the other element or layer, or intervening elements or layers can be present. For example, when an element is referred to as being "connected to" another element, it can be directly connected to the other element or connected thereto through intervening elements.

[0085] Furthermore, the reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0086] Figure 1 This is a schematic diagram of an exemplary auricle according to some embodiments of this specification. Figure 1 As shown, the auricle 100 may include an ear canal opening 101, a concha cavity 102, a cymba conchae 103, a triangular fossa 104, an antihelix 105, a scaphoid fossa 106, an helix 107, an earlobe 108, and a crus of the helix 109. It should be noted that, for ease of description, in this embodiment, the upper crus 1011 and lower crus 1012 of the antihelix, as well as the antihelix 105, are collectively referred to as the antihelix region. In some embodiments, the stability of headphone wearing can be achieved by using one or more parts of the auricle 100 to support the headphones. In some embodiments, the ear canal opening 101, the concha cavity 102, the cymba conchae 103, the triangular fossa 104, etc., have a certain depth and volume in three-dimensional space, which can be used to meet the wearing requirements of headphones. For example, headphones (e.g., in-ear headphones) can be worn in the ear canal opening 101. In some embodiments, headphones can be worn using other parts of the auricle 100 besides the ear canal opening 101. For example, the headphones can be worn using parts such as the cymba conchae 103, triangular fossa 104, antihelix 105, scaphoid 106, or helix 107, or combinations thereof. In some embodiments, to improve the comfort and reliability of the headphones, parts such as the user's earlobe 108 can also be used. By using parts of the auricle 100 other than the ear canal opening 101 to achieve headphone wearing and sound propagation, the user's ear canal opening 101 can be "liberated". When the user wears headphones (open-back headphones), the headphones do not block the user's ear canal opening 101, and the user can receive both sound from the headphones and sound from the environment (e.g., horns, car bells, surrounding voices, traffic signals, etc.), thereby reducing the probability of traffic accidents. In some embodiments, the headphones can be designed to fit the auricle 100 according to its structure, so that the sound-producing part of the headphones can be worn at different positions on the auricle. For example, when the headphones are open-back headphones, they may include a suspension structure (e.g., a wearing structure) and a sound-producing part, which is physically connected to the suspension structure. The suspension structure may be adapted to the shape of the auricle to place the entire or part of the auricle's sound-producing part on the front side of the helix 109 (e.g., Figure 1The area J enclosed by the dotted line. For example, when a user wears open-back headphones, the entire or partial structure of the sound-producing part can contact the upper part of the ear canal opening 101 (e.g., the location of one or more parts such as the helix crus 109, cymba conchae 103, triangular fossa 104, antihelix 105, scaphoid 106, and helix 107). For yet another example, when a user wears open-back headphones, the entire or partial structure of the sound-producing part can be located within the cavity formed by one or more parts of the auricle (e.g., the conchae cavity 102, cymba conchae 103, triangular fossa 104, etc.). Figure 1 The region M1, enclosed by the dotted line, includes at least the cymba conchae 103 and the triangular fossa 104, and the region M2, which includes at least the cavum conchae 102. Individual differences may exist among users, resulting in variations in the shape, size, and other dimensions of the auricle. For ease of description and understanding, unless otherwise specified, this specification will primarily use an auricle model with a "standard" shape and size as a reference to further describe how the headphones in different embodiments are worn on this auricle model.

[0087] The description of the auricle 100 above is for illustrative purposes only and is not intended to limit the scope of the invention. Those skilled in the art will recognize that various changes and modifications can be made based on the description. For example, a portion of the headphone structure may cover part or all of the ear canal opening 101. These changes and modifications are still within the scope of protection of this invention.

[0088] This invention provides an earphone 200, such as... Figures 1 to 3 As shown, the earphone 200 includes a first earphone body 10, a second earphone body 20, and a connecting arm 30. The second earphone body 20 can be arranged opposite to the first earphone body 10 and can be connected to it through the connecting arm 30.

[0089] Understandably, headphones may include, but are not limited to, air conduction headphones and bone conduction headphones. Specifically, in some embodiments, headphones may be combined with products such as glasses, headphones, head-mounted displays, and AR / VR headsets.

[0090] The first earphone body 10 may include an electroacoustic transducer 11, which converts electrical signals into sound waves, enabling the user to hear sound. Optionally, the electroacoustic transducer 11 may be a speaker, bone conduction device, etc. The connecting arm 30 may have a certain deformation capability to provide a certain clamping capability between the first earphone body 10 and the second earphone body 20.

[0091] The second earphone body 20 can include a housing 20d and a first microphone 230, the housing 20d includes clamping portions 21a, 21b, 21c and extension portions 22a, 22b, 22c, the extension portions 22a, 22b, 22c can be connected to the clamping portions 21a, 21b, 21c, the first microphone 230 can be arranged in the extension portions 22a, 22b, 22c, and the extension portions 22a, 22b, 22c can be provided with a first sound pickup hole 221, and the first microphone 230 can be used to pick up external sound through the first sound pickup hole 221.

[0092] When the earphone 200 is in a wearing state, the first earphone body 10 can be clamped in the concha cavity 102 of the pinna 100 of the user, and the sound emitted by the electro-acoustic transducer 11 can be conducted from the first earphone body 10 to the ear canal opening 101 of the pinna 100 of the user. The clamping portions 21a, 21b, 21c of the second earphone body 20 can abut the back of the pinna 100 of the user. That is, the connecting arm 30 allows the clamping portions 21a, 21b, 21c of the first earphone body 10 and the second earphone body 20 to be clamped on part of the pinna 100 of the user, so that the earphone 200 can be stably worn on the pinna 100 of the user.

[0093] In addition, the extension portions 22a, 22b, 22c of the second earphone body 20 can be close to the mouth of the user relative to the clamping portions 21a, 21b, 21c of the first earphone body 10, so that the first sound pickup hole 221 of the extension portions 22a, 22b, 22c can be close to the mouth of the user, so that the sound generated by the user can enter the extension portions 22a, 22b, 22c through the first sound pickup hole 221 within a short distance, and be collected by the first microphone 230, effectively improving the signal-to-noise ratio.

[0094] In summary, compared with the prior art, the earphone 200 has at least the following beneficial effects:

[0095] When the earphone 200 is in a wearing state, the first earphone body 10 can be clamped in the concha cavity 102 of the pinna 100 of the user, and the sound emitted by the electro-acoustic transducer 11 can be conducted from the first earphone body 10 to the ear canal opening 101 of the pinna 100 of the user. The clamping portions 21a, 21b, 21c of the second earphone body 20 can abut the back of the pinna 100 of the user. That is, the connecting arm 30 allows the clamping portions 21a, 21b, 21c of the first earphone body 10 and the second earphone body 20 to be clamped on part of the pinna 100 of the user, so that the earphone 200 can be stably worn on the pinna 100 of the user.

[0096] The first microphone 230 of the second earphone body 20 is arranged in the extension part 22a, 22b, 22c, and the extension part 22a, 22b, 22c is close to the mouth of the user relative to the first earphone body 10 and the clamping part 21a, 21b, 21c, that is, the distance between the pickup structure of the earphone 200 and the mouth of the user is shortened, so as to reduce the environmental noise interference, enhance the signal strength, make the sound clearer, effectively improve the call quality of the ear clip earphone 200, and make the user in the scene of driving, ordering food or delivering goods, and business people working and communicating by telephone at the same time, etc. can do other things in the state of smooth telephone communication, so that the application scene of the earphone 200 is rich and the use feeling of the user is significantly improved.

[0097] In order for those skilled in the art to better understand the technical solutions of the present application, the following will combine the accompanying drawings to Figures 1 to 10 The technical solutions in the embodiments of the present application are clearly and completely described.

[0098] In some embodiments, as shown in Figure 5 , the second earphone body 20 includes an energy storage device 233 and a circuit board 234, the energy storage device 233 can be a battery or a battery pack, etc., and the circuit board 234 can be a hard circuit board or a flexible circuit board, etc. The energy storage device 233 and the circuit board 234 can be arranged in the second earphone body, and the electro-acoustic transducer 11, the microphone and the energy storage device 233 can be electrically connected to the circuit board 234.

[0099] In some embodiments, as shown in Figure 3 and Figure 10 , the extension part 22a, 22b, 22c and the clamping part 21a, 21b, 21c can be integrally formed, which is convenient for manufacturing and mass production. Alternatively, the extension part 22a, 22b, 22c and the clamping part 21a, 21b, 21c can also be separately arranged, that is, they are detachable structures, so that the structure of the earphone 200 has a certain flexibility.

[0100] In some embodiments, as shown in Figure 3 , Figure 8 and Figure 10 , the extension part 22a, 22b, 22c can have a first end 227, and the first pickup hole 221 can be arranged at the first end 227. The first end 227 can be the end of the extension part 22a, 22b, 22c away from the clamping part 22a, 22b, 22c, so that the first pickup hole 221 can be as close to the user's mouth as possible when the earphone 200 is in the wearing state. Further improve the pickup effect of the sound emitted by the user to the earphone 200.

[0101] Optionally, the first pickup hole 221 can be located on any side of the extension portions 22a, 22b, 22c. When the first pickup hole 221 is located on any one of the upper, lower, front, or rear sides of the extension portions 22a, 22b, 22c, regardless of whether the earphone 200 is in the first or second posture (i.e., whether it is fitted to the left or right ear), the distance between the first pickup hole 221 and the user's mouth is similar, and the first pickup hole 221 is not located on a side away from the user's mouth. This ensures that the earphone 200 provides similar and good sound pickup effects when fitted to either the left or right ear.

[0102] In some embodiments, as an implementation where the extension portion 22a and the clamping portion 21a are integrally formed, such as... Figure 1 and Figure 3 As shown, the first earphone body 10 is movable relative to the clamping portion 21a, so that the first earphone body 10 can form a first posture and a second posture relative to the clamping portion 21a. Wherein:

[0103] Combined with appendix Figure 4 In Figure (a), in the first posture, when the earphone 200 is worn on the user's left ear, the first earphone body 10 can move relative to the clamping part 21a until the first earphone body 10 can be clamped in the concha cavity 102 of the user's left auricle 100, and the clamping part 21a can abut against the back of the user's left auricle 100, so that the first earphone body 10 and the second earphone body 20 cooperate to clamp the part of the auricle 100 of the user's left ear, that is, the earphone 200 can be stably worn on the user's left ear in the first posture.

[0104] Combined with appendix Figure 4 In Figure (b), in the second posture, when the earphone 200 is worn on the user's right ear, the first earphone body 10 can move relative to the clamping part 21a until the first earphone body 10 can be clamped in the concha cavity 102 of the user's right auricle 100, and the clamping part 21a can abut against the back of the user's right auricle 100, so that the first earphone body 10 and the second earphone body 20 cooperate to clamp the part of the auricle 100 of the user's right ear, that is, the earphone 200 can be stably worn on the user's right ear in the second posture.

[0105] Understandably, by adjusting the relative positional relationship between the first earphone body 10 and the second earphone body 20, the first earphone body 10 and the second earphone body 20 can switch between a first posture and a second posture, so that one earphone 200 can be adapted to the user's left ear and right ear respectively in different postures, thereby improving the flexibility of the earphone 200 structure.

[0106] In some embodiments, such as Figure 4As shown, the second earphone body 20 can have a second symmetry plane (O2-O2 plane), and the outer surface of the second earphone body 20 includes a first side 201a and a second side 202a oppositely arranged with respect to the second symmetry plane (O2-O2 plane). Wherein:

[0107] In combination with (a) of FIG. 1, in the first posture, when the earphone 200 is worn on the left ear of the user, the first side 201a can be away from the mouth of the user relative to the second side 202a, and the first earphone body 10 and the connecting arm 30 can be located on the first side 201a. Figure 4 In combination with (b) of FIG. 1, in the second posture, when the earphone 200 is worn on the right ear of the user, the second side 202a can be away from the mouth of the user relative to the first side 201a, and the first earphone body 10 and the connecting arm 30 can be located on the second side 202a.

[0108] Figure 4 It can be understood that, since the first side 201a and the second side 202a of the second earphone body 20 are oppositely arranged with respect to the second symmetry plane (O2-O2 plane), when the first earphone body 10 and the connecting arm 30 are simultaneously located on the first side 201a or simultaneously located on the second side 202a, they are also oppositely arranged with respect to the second symmetry plane (O2-O2 plane), and are positionally changed with respect to the second symmetry plane (O2-O2 plane) to adapt to the left ear or the right ear of the user, so that the earphone 200 can adapt to the left ear and the right ear of the user in similar structures in the first posture and the second posture.

[0109] Wherein, the oppositely arranged first side 201a and the second side 202a of the second earphone body 20 with respect to the second symmetry plane (O2-O2 plane) means that the first side 201a and the second side 202a are arranged on both sides of the second symmetry plane, and the first side 201a and the second side 202a are opposite with respect to the second symmetry plane, in other words, the first side 201a and the second side 202a are non-perpendicular and non-coincident planes, for example, the first side 201a and the second side 202a can be symmetric planes with respect to the second symmetry plane, or can be opposite and parallel planes with respect to the second symmetry plane, or can be approximately symmetric planes with respect to the second symmetry plane (i.e., there can be some differences on the basis of the two planes being generally symmetric), and the like.

[0110] In some embodiments, as shown in (a) of FIG. 1, the first side 201a and the second side 202a can be symmetric with respect to the second symmetry plane (O2-O2 plane), so that the surface of the side of the second earphone body 20 towards the head of the user (i.e., the first side 201a or the second side 202a) is the same in the first posture or the second posture, which can improve the adaptability of the earphone 200 when worn on the left ear and the right ear of the user, respectively.

[0111] In some embodiments, as shown in (a) of FIG. 1, the first side 201a and the second side 202a can be symmetric with respect to the second symmetry plane (O2-O2 plane), so that the surface of the side of the second earphone body 20 towards the head of the user (i.e., the first side 201a or the second side 202a) is the same in the first posture or the second posture, which can improve the adaptability of the earphone 200 when worn on the left ear and the right ear of the user, respectively. Figure 4 In some embodiments, as shown in (a) of FIG. 1, the first side 201a and the second side 202a can be symmetric with respect to the second symmetry plane (O2-O2 plane), so that the surface of the side of the second earphone body 20 towards the head of the user (i.e., the first side 201a or the second side 202a) is the same in the first posture or the second posture, which can improve the adaptability of the earphone 200 when worn on the left ear and the right ear of the user, respectively.​

[0112] In some embodiments, as shown in Figure 4 the outer surface of the second earphone body 20 can be symmetrical about the second symmetry plane (O2-O2 plane), so that the second earphone body 20 can be adaptively clamped on the back of the pinna 100 of the left ear or the right ear in the first attitude or the second attitude, and the user's experience of using the second earphone body 20 is the same when the earphone 200 is worn on the left ear or the right ear, further improving the adaptability of the earphone 200 when worn on the left ear and the right ear of the user respectively.

[0113] In some embodiments, as shown in Figure 4 the first earphone body 10 in the first attitude, the connecting arm 30 and the first earphone body 10 in the second attitude, the connecting arm 30 can be symmetrically arranged about the second symmetry plane (O2-O2 plane).

[0114] It can be understood that the first earphone body 10 and the connecting arm 30 are simultaneously located on the first side 201a or simultaneously located on the second side 202a, and there is no substantial change in their structural functions, only the position conversion of the first earphone body 10 and the connecting arm 30 is made about the second symmetry plane (O2-O2 plane) mirror image arrangement to adapt to the left ear or the right ear of the user, so that the earphone 200 can adapt to the left ear or the right ear of the user with the same structure, the same wearing method and the same wearing position relationship in the first attitude or the second attitude, so as to further improve the adaptability of the earphone 200 when worn on the left ear and the right ear of the user respectively.

[0115] In some embodiments, as shown in Figure 4 the first earphone body 10 can have a first symmetry plane (O1-O1 plane), and the outer surface of the first earphone body 10 can be symmetrical about the first symmetry plane (O1-O1 plane), and the outer surface of the connecting arm 30 can be symmetrical about the first symmetry plane (O1-O1 plane).

[0116] It can be understood that the upper half of the outer surface of the first earphone body 10 and the connecting arm 30 in the first attitude is located in the lower half thereof in the second attitude, and the lower half of the outer surface of the first earphone body 10 and the connecting arm 30 in the first attitude is located in the upper half thereof in the second attitude, that is, the first earphone body 10 and the connecting arm 30 are in an upside-down relationship in the first attitude and the second attitude. Based on this, the outer surface of the first earphone body 10 and the outer surface of the connecting arm 30 are symmetrical about the first symmetry plane (O1-O1 plane), so that the wearing structure and the wearing position relationship of the first earphone body 10 will not change whether it is in the first attitude or the second attitude, so that the comfort and the audio output quality of the earphone 200 will not be different whether it is worn on the left ear or the right ear, and the adaptability of the left ear and the right ear is further improved.

[0117] In some embodiments, as shown inFigure 4 As shown, in the first and second postures, the second symmetry plane (O2-O2 plane) and the first symmetry plane (O1-O1 plane) can be perpendicular to each other, that is, the first earphone body 10 and the connecting arm 30 can be perpendicular to each other with the second earphone body 20. When the earphone 200 is in the wearing state, the first earphone body 10 can be precisely held within the concha 102 of the user's auricle 100, and the clamping portion 21a of the second earphone body 20 can precisely abut against the back of the user's auricle 100, further enhancing the clamping ability between the first earphone body 10 and the second earphone body 20. Simultaneously, it also facilitates the switching of the earphone 200 between the first and second postures.

[0118] Since the shape of the auricle 100 may vary greatly among different users, in other embodiments, the angle between the second symmetry plane (O2-O2 plane) and the first symmetry plane (O1-O1 plane) may also be acute in the first and second postures.

[0119] In some embodiments, such as Figure 4 As shown, the second earphone body 20 may have a reference surface (O3-O3 plane), which may be perpendicular to the second symmetry plane (O2-O2 plane). Since the first and second postures of the earphone 200 are symmetrical about the second symmetry plane (O2-O2 plane), and the outer surface of the second earphone body 20 only needs to be symmetrical about the second symmetry plane (O2-O2 plane) to fit the user's left and right ears, the outer surface of the second earphone body 20 may not be specifically restricted about the reference surface (O3-O3 plane), making the design of the outer surface of the second earphone body 20 more flexible.

[0120] Optionally, the outer surface of the second earphone body 20 may be asymmetrically arranged with respect to the reference surface, so that the length of the extension portion 22a is longer than the length of the clamping portion 21a, so that when the earphone 200 is worn on the user's ear, the extension portion 22a can be closer to the user's mouth.

[0121] Of course, the outer surface of the second earphone body 20 can also be symmetrical about the reference plane (O3-O3 plane).

[0122] In some embodiments, such as Figure 4 As shown, the connecting arm 30 is movably or detachably connected to the clamping portion 21a, so that the connecting arm 30 and the first earphone body 10 connected to the connecting arm 30 can switch between the first side 201a and the second side 202a on the outer surface of the second earphone body 20, so that the first earphone body 10 can form a first posture and a second posture relative to the second earphone body 20.

[0123] Optionally, the connecting arm 30 may be rotatably connected to the clamping part 21, or it may be slidably connected to the clamping part 21, or it may be rollably connected to the clamping part 21, etc.

[0124] Optionally, the connecting arm 30 can be detachably connected to the clamping part 21 by snapping the connecting arm 30 to the clamping part 21, or by magnetically attaching the connecting arm 30 to the clamping part 21, etc.

[0125] In some embodiments, as an implementation where the connecting arm 30 is detachably connected to the clamping portion 21a, such as... Figure 3 and Figure 4 As shown, the clamping portion 21a may be provided with a first mounting hole 211a and a second mounting hole 212a. The first mounting hole 211a may be located on a first side 201a, and the second mounting hole 212a may be located on a second side 202a. The first mounting hole 211a and the second mounting hole 212a may be arranged opposite each other about a second symmetry plane (O2-O2 plane). Wherein:

[0126] Combined with appendix Figure 4 In Figure (a), in the first posture, the connecting arm 30 is detachably connected to the first mounting hole 211a, so that the first earphone body 10 and the connecting arm 30 are located on the first side 201a, so that the earphone 200 can be worn on the user's left ear in this posture.

[0127] Combined with appendix Figure 4 In Figure (b), in the second posture, the connecting arm 30 is detachably connected to the second mounting hole 212a, so that the first earphone body 10 and the connecting arm 30 are located on the second side 202a, so that the earphone 200 can be worn on the user's right ear in this posture.

[0128] Specifically, the connecting arm 30 can be detachably connected to the first mounting hole 211a and the second mounting hole 212a by means of plugging or screwing.

[0129] In some embodiments, as a first implementation where the connecting arm 30 is movably connected to the clamping portion 21a, such as Figure 6 As shown, the connecting arm 30 is rotatably connected to the second earphone body 20 about a first direction (z1 direction), so that the first earphone body 10 can form a first posture and a second posture relative to the second earphone body 20. Specifically, in this embodiment, the connecting arm 30 is rotatably connected to the end of the clamping portion 21a of the second earphone body 20 about a first direction (z1 direction). Wherein:

[0130] In the first posture, the connecting arm 30 is rotated around the second earphone body 20 along the first direction (z1 direction) to the first side 201a where the first earphone body 10 and the connecting arm 30 are located, so that the first earphone body 10 and the connecting arm 30 are located on the first side 201a, and the first earphone body 10 is rotated to be clamped in the concha cavity 102 of the left ear of the user, so that the earphone 200 can be worn at the left ear of the user in this posture.

[0131] In the second posture, the connecting arm 30 is rotated around the second earphone body 20 along the first direction (z1 direction) to the second side 202a where the first earphone body 10 and the connecting arm 30 are located, so that the first earphone body 10 and the connecting arm 30 are located on the second side 202a, and the first earphone body 10 is rotated to be clamped in the concha cavity 102 of the right ear of the user, so that the earphone 200 can be worn at the right ear of the user in this posture.

[0132] Optionally, as shown in Figure 6 , one end of the connecting arm 30 is connected with the first earphone body 10, and the other end is provided with a ring-shaped piece 31a. The first microphone 230 is arranged in one end of the second earphone body 20, the ring-shaped piece 31a can be clamped in the one end of the second earphone body 20, and the ring-shaped piece 31a can be rotated along the first direction (z1 direction) relative to the one end, so that the connecting arm 30 and the first earphone body 10 can be rotated to the first side 201 and / or the second side 202 of the second earphone body 20, so as to realize that the earphone 200 can be adapted to the left ear and the right ear of the user in the first posture and the second posture respectively.

[0133] In some embodiments, as a second implementation mode that the connecting arm 30 is movably connected to the clamping part 21a, as shown in Figure 7 , the connecting arm 30 is rotatably connected to the second earphone body 20 around the second direction (z2 direction) and the third direction (z3 direction), so that the first earphone body forms the first posture and the second posture relative to the second earphone body; the second direction (z2 direction) can intersect the third direction (z3 direction). Wherein:

[0134] In the first posture, the connecting arm 30 is rotated around the second earphone body 20 along the second direction (z2 direction) to the first side 201a where the first earphone body 10 and the connecting arm 30 are located, so that the first earphone body 10 and the connecting arm 30 are located on the first side 201a; the connecting arm 30 is rotated around the second earphone body 20 along the third direction (z3 direction) to rotate the first earphone body 10 to be clamped in the concha cavity 102 of the left ear of the user, so that the earphone 200 can be worn at the left ear of the user in this posture.

[0135] In the second posture, the connecting arm 30 rotates around the second earphone body 20 along the second direction (z2 direction) until the connecting arm 30 and the first earphone body 10 are located on the second side 202a, so that the first earphone body 10 and the connecting arm 30 are located on the second side 202a; the connecting arm 30 rotates around the second earphone body 20 along the third direction (z3 direction) so that the first earphone body 10 rotates to be able to be held in the concha 102 of the user's right ear, so that the earphone 200 can be worn on the user's right ear in this posture.

[0136] Optionally, such as Figure 7 As shown, one end of the connecting arm 30 is connected to the first earphone body 10, and the other end may be provided with a spherical component 32a. The spherical component 32a can be locked between the two ends of the second earphone body 20, and the spherical component 32a can rotate relative to this end along the second direction (z2 direction), so that the connecting arm 30 and the first earphone body 10 can rotate to the first side 201 and / or the second side 202 of the second earphone body 20, so that the earphone 200 can adapt to the user's left ear and right ear in the first posture and the second posture respectively.

[0137] In some embodiments, such as Figure 4 As shown, the first microphone 230 can be located on the second symmetry plane (O2-O2 plane), and the extended portion 22a can also be provided with a second pickup hole 222. The first pickup hole 221 can be located on the first side 201a, and the second pickup hole 222 can be located on the second side 202a. The first pickup hole 221 and the second pickup hole 222 can be arranged opposite to each other about the second symmetry plane (O2-O2 plane). Wherein:

[0138] Combined with appendix Figure 4 In Figure (a), in the first posture, when the headset 200 is worn on the user's left ear, the first microphone 230 can be used to pick up external sounds through the second pickup hole 222. Since the second side 202a is close to the user's mouth in this posture, the first microphone 230 can mainly pick up the user's voice through the second pickup hole 222 when the user is in a call.

[0139] Combined with appendix Figure 4 In Figure (b), in the second posture, when the headset 200 is worn on the user's left ear, the first microphone 230 can be used to pick up external sounds through the first pickup hole 221. Since the first side 201a is close to the user's mouth in this posture, the first microphone 230 can mainly pick up the user's voice through the first pickup hole 221 when the user is in a call.

[0140] In this way, the earphone 200 can pick up the sound emitted by the user through the sound pickup hole arranged on the side of the extension portion 22 close to the user's mouth in the first posture or the second posture, i.e., whether the earphone 200 is adapted to the left ear or the right ear, which is beneficial to improve the sound pickup effect of the earphone 200. At the same time, since the first microphone 230 is located on the second symmetry plane (O2-O2 plane), the distance between the first microphone 230 and the first sound pickup hole 221 and the distance between the first microphone 230 and the second sound pickup hole 222 are relatively close, so that the sound pickup effect of the first microphone 230 through the first sound pickup hole 221 and the second sound pickup hole 222 is substantially the same, thereby making the earphone 200 have substantially the same sound pickup effect when worn on the left ear or the right ear, improving the user's experience.

[0141] In some embodiments, when the extension portion 22a and the clamping portion 21a are integrally formed, the first earphone body 10 and the connecting arm 30 are detachably connected, so as to replace the first earphone body 10 by taking off the first earphone body 10 from the connecting arm 30.

[0142] Alternatively, the clamping portion 21a and the connecting arm 30 are detachably connected, so as to replace the first earphone body 10 by taking off the connecting arm 30 and the first earphone body 10 connected to the connecting arm 30 from the clamping portion 21a. That is, when the first earphone body 10 needs to be repaired or is adapted to the concha cavity 102 of different users, the first earphone body 10 can be replaced in the above-mentioned manner.

[0143] In some embodiments, as an implementation manner that the extension portion 22b and the clamping portion 21b are separately arranged, as shown in Figure 8 and Figure 9 , the extension portion 22b is movable relative to the clamping portion 21b, so that the extension portion 22b forms a third posture and a fourth posture relative to the clamping portion 21b. Wherein:

[0144] In combination with (c) of FIG. 1, Figure 9 In the third posture, when the earphone 200 is worn on the left ear of the user, the extension portion 22b can be moved relative to the clamping portion 21b so that the first earphone body 10 can be clamped in the concha cavity 102 of the left auricle 100 of the user, and the clamping portion 21b can abut against the back of the left auricle 100 of the user, so that the first earphone body 10 and the second earphone body 20 cooperate to be clamped on the part of the auricle 100 of the left ear of the user, so that the earphone 200 can be stably worn on the left ear of the user in the third posture.

[0145] In combination with (c) of FIG. 1, Figure 9In Figure (d), in the fourth posture, when the earphone 200 is worn on the user's right ear, the extension portion 22b can move relative to the clamping portion 21b so that the first earphone body 10 is clamped in the concha cavity 102 of the user's right auricle 100, and the clamping portion 21b abuts against the back of the user's right auricle 100, so that the first earphone body 10 and the second earphone body 20 cooperate to clamp the part of the auricle 100 of the user's right ear, so that the earphone 200 can be stably worn on the user's right ear in the fourth posture.

[0146] In some embodiments, if there is no need for a call or a long call at the moment, and the only need is to listen to audio information (such as music, radio, audiobooks, etc.) through the headset 200, the extension portion 22b can be removed from the clamping portion 21b to reduce the weight of the headset 200.

[0147] In some embodiments, such as Figure 9 As shown, the extension portion 22b may have a second plane of symmetry (O2-O2 plane), and the outer surface of the extension portion 22b may include a third side 223b and a fourth side 224b opposite to each other with respect to the second plane of symmetry (O2-O2 plane). Wherein:

[0148] Combined with appendix Figure 9 In Figure (c), in the third posture, when the earphone 200 is worn on the user's left ear, the third side 223b can be away from the user's mouth relative to the fourth side 224b, and both the first earphone body 10 and the connecting arm 30 can be located on the third side 223b.

[0149] Combined with appendix Figure 9 In Figure (d), in the fourth posture, when the earphone 200 is worn on the user's right ear, the fourth side 224b can be away from the user's mouth relative to the third side 223b, and both the first earphone body 10 and the connecting arm 30 can be located on the fourth side 224b.

[0150] Understandably, since the third side 223b and the fourth side 224b of the second earphone body 20 are arranged opposite each other about the second symmetry plane (O2-O2 plane), when the first earphone body 10 and the connecting arm 30 are simultaneously located on the first side 201a or simultaneously located on the second side 202a, their structures are arranged opposite each other about the second symmetry plane (O2-O2 plane) to adapt to the user's left or right ear. That is, the earphone 200 can adapt to the user's left and right ears respectively with similar structures in the third and fourth postures.

[0151] The fact that the first side 201 and the second side 202 of the extended portion 22b are arranged opposite each other about the second plane of symmetry (O2-O2 plane) means that the first side 201 and the second side 202 are arranged on both sides of the second plane of symmetry (O2-O2 plane), and the first side 201 and the second side 202 are opposite each other about the second plane of symmetry (O2-O2 plane). In other words, the first side 201 and the second side 202 are non-perpendicular and non-coincident surfaces. For example, the first side 201 and the second side 202 can be symmetrical about the second plane of symmetry (O2-O2 plane), or they can be opposite and parallel about the second plane of symmetry (O2-O2 plane), or they can be nearly symmetrical about the second plane of symmetry (O2-O2 plane) (that is, there can be some differences on the basis of the two surfaces being generally symmetrical), and so on.

[0152] In some embodiments, such as Figure 9 As shown, the third side 223b and the fourth side 224b are symmetrical about the second symmetry plane (O2-O2 plane), so that the second earphone body 20 can fit comfortably on the back of the auricle 100 of the left or right ear regardless of whether the second earphone body 20 is in the third or fourth posture, and the first pickup hole 221 of the extended part 22b can also be close to the user's mouth, further improving the fit of the earphone 200 when worn on the user's left and right ears respectively.

[0153] In some embodiments, such as Figure 9 As shown, the outer surface of the extended portion 22b can be symmetrical about the second symmetry plane (O2-O2 plane), so that the second earphone body 20 can fit properly on the back of the auricle 100 of the left or right ear regardless of whether the second earphone body 20 is in the third or fourth posture, further improving the fit of the earphone 200 when worn on the user's left and right ears respectively.

[0154] In some embodiments, such as Figure 6 As shown, the first earphone body 10, connecting arm 30, and clamping part 21b in the third posture and the first earphone body 10, connecting arm 30, and clamping part 21b in the fourth posture can all be symmetrically arranged about the second symmetry plane (O2-O2 plane).

[0155] Understandably, the fact that the first earphone body 10 and the connecting arm 30 are simultaneously located on the third side 223b or the fourth side 224b does not substantially change their structure. It is only a positional transformation about the second symmetry plane (O2-O2 plane) to adapt to the user's left or right ear. This allows the earphone 200 to adapt to the user's left or right ear with the same structure, the same wearing method, and the same wearing position relationship, regardless of whether the earphone 200 is in the third or fourth posture. This further improves the fit of the earphone 200 when worn on the user's left and right ears.

[0156] In some embodiments, such asFigure 9 As shown, the first earphone body 10 can have a first symmetry plane (O1-O1 plane), the outer surface of the first earphone body 10 can be symmetrical about the first symmetry plane (O1-O1 plane), the outer surface of the connecting arm 30 can be symmetrical about the first symmetry plane (O1-O1 plane), and the outer surface of the clamping portion 21b can be symmetrical about the first symmetry plane (O1-O1 plane).

[0157] Understandably, the upper half of the outer surface of the first earphone body 10 in the third attitude is located in the lower half thereof in the fourth attitude, and the lower half of the outer surface of the first earphone body 10 in the third attitude is located in the upper half thereof in the fourth attitude; the upper half of the outer surface of the clamping portion 21b in the third attitude is located in the lower half thereof in the fourth attitude, and the lower half of the outer surface of the clamping portion 21b in the third attitude is located in the upper half thereof in the fourth attitude.

[0158] Based on this, the outer surface of the first earphone body 10, the outer surface of the connecting arm 30, and the outer surface of the clamping portion 21b are symmetrical about the first symmetry plane (O1-O1 plane), so that the first earphone body 10 does not change its wearing structure and wearing position relationship when it is in the third attitude or the fourth attitude, and the comfort and audio output quality of the earphone 200 do not have too much difference when it is worn on the left ear or the right ear, and the adaptability of the left ear and the right ear is further improved.
