Description

Technical Field

[0001] This invention relates to the field of acoustic technology, and more particularly to an earphone and a pair of earphones. Background Technology

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

[0003] Depending on the wearing method, headphones can be divided into in-ear, semi-in-ear, and over-ear types. In-ear and semi-in-ear headphones need to be inserted into the ear canal for use. However, this type of headphone relies on the ear canal for support, which can lead to ear fatigue or discomfort after prolonged wear. This may be uncomfortable for some users, and the direct sound transmission principle poses a potential risk of hearing damage with long-term use. Over-ear headphones, on the other hand, cover the auricle, which can create pressure on the ear. Currently, clip-on headphones, which are worn by clamping two earpieces onto the auricle, are gaining popularity among consumers because they do not require insertion into the ear canal or covering the auricle.

[0004] However, most earphones on the market that allow for interchangeable left and right earpieces generally exhibit significant differences in sound quality and call quality when switched between the two earpieces. This severely limits the application scenarios for clip-on earphones. For example, drivers who need to make calls while driving, delivery drivers or couriers who need to answer customer calls while cycling, and business people who need to make phone calls and operate computers simultaneously while working may experience a decline in sound quality and call quality when switching earphones due to fatigue in one ear after prolonged use, resulting in a significantly reduced user experience. Summary of the Invention

[0005] The purpose of this invention is to solve the technical problem that existing earphones that can be interchanged between the left and right ears have significant differences in sound quality, call quality, and other functions when the wearing status is changed.

[0006] To solve the above-mentioned technical problems, this utility model provides an earphone, which adopts the following technical solution:

[0023] The second earphone body further includes a first microphone, which is disposed inside the housing and located on the second plane of symmetry;

[0024] The first structure includes a third pickup hole, and the second structure includes a fourth pickup hole. The third pickup hole is located on the first side, and the fourth pickup hole is located on the second side. The third pickup hole and the fourth pickup hole are symmetrically arranged about the second symmetrical surface.

[0025] When the earphone is worn on the user's left ear, the first microphone is used to pick up external sounds through the fourth pickup hole;

[0026] When the earphone is worn on the user's right ear, the first microphone is used to pick up external sounds through the third pickup hole.

[0027] As an optional implementation, the second earphone body further includes a second microphone, which is disposed inside the housing, spaced apart from the first microphone, and located on the second plane of symmetry;

[0028] The first structure further includes a fifth pickup hole, and the second structure further includes a sixth pickup hole. The fifth pickup hole is disposed on the first side, and the sixth pickup hole is disposed on the second side. The fifth pickup hole and the sixth pickup hole are symmetrically arranged about the second symmetrical surface, and the third pickup hole and the fourth pickup hole are close to the user's mouth relative to the fifth pickup hole and the sixth pickup hole.

[0029] When the earphone is worn on the user's left ear, the second microphone is used to pick up external sounds through the sixth pickup hole;

[0030] When the earphone is worn on the user's right ear, the second microphone is used to pick up external sounds through the fifth pickup hole.

[0031] As an optional implementation, the housing includes a clamping portion and an extension portion, the extension portion being connected to the clamping portion, the connecting arm being connected to the clamping portion, the extension portion having a first end, and the functional structure being at least partially disposed at the first end, the first end being the end of the extension portion away from the clamping portion.

[0032] As an optional implementation, the first earphone body can move relative to the second earphone body, so that the first earphone body forms a first posture and a second posture relative to the second earphone body;

[0040] Compared with the prior art, the headphones provided by this utility model have the following advantages:

[0041] The headphones include a first earphone body and a second earphone body, which are positioned opposite each other and connected by a connecting arm. When the headphones are worn, the first earphone body is held in place within the concha of the user's ear, and the sound emitted by the electroacoustic transducer of the first earphone body can be transmitted from the first earphone body to the ear canal opening of the user's ear. The second earphone body rests against the back of the user's ear, and the connecting arm provides a certain clamping force between the two, that is, the first earphone body and the second earphone body cooperate to clamp a portion of the user's ear, so that the headphones can be stably worn on the user's ear by this clamping method, effectively improving the stability of wearing the headphones.

[0042] At least a portion of the functional structure of the second earpiece can be symmetrically arranged about the second symmetrical surface. Based on this, in situations where users such as drivers needing to make calls while driving, delivery drivers or couriers needing to answer customer calls while riding, or business people needing to simultaneously conduct phone conversations and operate computers while working, and where prolonged use of one ear leads to fatigue and necessitates switching to the other ear, the quality of sound playback and call functions can be guaranteed regardless of whether the earpiece is worn in the left or right ear. This enriches the application scenarios of the earpiece and significantly improves the user experience. Attached Figure Description

[0052] 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 invention pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. For example, terms such as “length,” “width,” “upper,” “lower,” “left,” “right,” “front,” “rear,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer” indicate orientations or positions based on the orientations or positions shown in the accompanying drawings and are merely for ease of description and should not be construed as limiting the invention.

[0053] The terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings of this utility model are intended to cover non-exclusive inclusion; the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish different objects, not to describe a specific order. "A plurality of" means two or more, unless otherwise explicitly specified.

[0054] In the description, claims, and accompanying drawings of this utility model, when an element is referred to as "fixed to," "mounted to," "set on," or "connected to" another element, it can be directly or indirectly located on that other element. For example, when an element is referred to as "connected to" another element, it can be directly or indirectly connected to that other element.

[0055] 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 present 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.

[0056] Figure 1 This is a schematic diagram of an exemplary auricle according to some embodiments of this specification. For example... 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.

[0057] The description of the auricle 100 above is for illustrative purposes only and is not intended to limit the scope of this utility model. Those skilled in the art can make various changes and modifications based on the description of this utility model. For example, part of the headphone structure can cover part or all of the ear canal opening 101. These changes and modifications are still within the protection scope of this utility model.

[0058] It should also be noted that the headphones may include, but are not limited to, air conduction headphones and bone conduction headphones. Specifically, in some embodiments, the headphones may be combined with products such as glasses, headphones, head-mounted displays, and AR / VR headsets.

[0059] This utility model embodiment provides an earphone 200, such as Figures 2 to 4 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.

[0060] It is understood that the earphone 200 of this utility model may include, but is not limited to, air conduction earphones and bone conduction earphones. Specifically, in some embodiments, the earphone 200 may be combined with products such as glasses, headphones, head-mounted display devices, and AR / VR helmets.

[0061] 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.

[0062] The connecting arm 30 can have a certain deformation capability so that the first earphone body 10 and the second earphone body 20 have a certain clamping capability.

[0063] In some embodiments, the earphone 200 may be configured to fit the user's left and right ears. The second earphone body 20 may have a second plane of symmetry (O2-O2 plane), and the outer surface of the second earphone body 20 includes a first side 201 and a second side 202 disposed opposite to each other about the second plane of symmetry (O2-O2 plane). Wherein:

[0064] Combined with appendix Figure 4 In Figure (a), when the earphone 200 is worn on the user's left ear, the first earphone body 10 can move relative to the second earphone body 20 until the first earphone body 10 can be held in the concha cavity 102 of the user's left auricle 100, and the second earphone body 20 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 hold part of the auricle 100 of the user's left ear; and the first side 201 can be away from the user's mouth relative to the second side 202.

[0065] 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 second earphone body 20 until the first earphone body 10 can be held in the concha cavity 102 of the user's right auricle 100, and the second earphone body 20 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 hold part of the auricle 100 of the user's right ear; and the second side 202 can be away from the user's mouth relative to the first side 201.

[0066] In some embodiments, the second earphone body 20 includes a housing 20a and a functional structure 23, which may be disposed within the housing 20a and at least partially located on the outer surface of the second earphone body 20.

[0067] Optionally, the functional structure 23 may be partially located on the outer surface of the second earphone body 20, or it may be entirely located on the outer surface of the second earphone body 20.

[0068] Optionally, the functional structure 23 may be a pickup hole, button, or touch screen provided on the outer surface of the second earphone body 20.

[0069] The functional structure 23 can be symmetrically arranged at least partially about the second symmetry plane (O2-O2 plane) so that the functional structure 23 is universal when the earphone 200 is worn in the user's left or right ear, that is, the quality of the earphone's playback, call, control and other functions can be guaranteed regardless of whether it is worn in the left or right ear.

[0070] In summary, compared with existing technologies, this headset 200 has at least the following beneficial effects:

[0071] The earphone 200 includes a first earphone body 10 and a second earphone body 20, which are arranged opposite to each other and connected by a connecting arm 30. When the earphone 200 is in the wearing state, the first earphone body 10 is held in the concha 102 of the user's auricle 100, and the sound emitted by the electroacoustic transducer of the first earphone body 10 can be transmitted from the first earphone body 10 to the ear canal opening of the user's auricle 100; the second earphone body 20 abuts against the back of the user's auricle 100, and the connecting arm 30 provides a certain clamping force between the two, that is, the first earphone body 10 and the second earphone body 20 cooperate to clamp a part of the user's auricle 100, so that the earphone 200 can be stably worn on the user's auricle 100 through this clamping method, effectively improving the wearing stability of the earphone 200.

[0072] At least a portion of the functional structures 23 of the second earpiece 20 can be symmetrically arranged about the second plane of symmetry (O2-O2 plane). Based on this, in situations where users such as drivers needing to make calls while driving, delivery drivers or couriers needing to answer customer calls while riding, or business people needing to simultaneously conduct phone conversations and operate computers while working, and where prolonged use of one ear leads to fatigue requiring switching to the other, the quality of sound playback, calls, and controls of the earpiece 200 can be guaranteed regardless of whether it is worn in the left or right ear. This enriches the application scenarios of the earpiece 200 and significantly improves the user experience.

[0073] To enable those skilled in the art to better understand the present invention, the following will be described in conjunction with the appendix. Figures 1 to 5 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0074] In some embodiments, such as Figure 4 As shown, the functional structure 23 can be disposed on at least one of the upper, lower, front and rear sides of the housing 20a, and at least a portion of the functional structure 23 itself can be symmetrically disposed about the second symmetry plane (O2-O2 plane).

[0075] Alternatively, the functional structure 23 may include a first structure and a second structure. The first structure may be located on the first side 201, and the second structure may be located on the second side 202. At least a portion of the first structure and the second structure may be symmetrically arranged about the second symmetry plane (O2-O2 plane), and the first structure may have the same function as the second structure.

[0076] In some embodiments, as one implementation of functional structure 23, such as Figure 4As shown in Figure (b), the functional structure 23 is located on at least one of the upper, lower, front, and rear sides of the housing 20a. When the second earphone body 20 is used, a first microphone 230 may be provided inside to pick up sounds from the external environment; and the first microphone 230 may be located on the second symmetry plane (O2-O2 plane) so that the sound pickup quality of the first microphone 230 is not affected regardless of whether the earphone 200 is fitted to the left or right ear.

[0077] Optionally, the functional structure 23 may be configured in the following ways: the functional structure 23 may be located on the upper and lower sides of the second earphone body 20; the functional structure 23 may be located on the front and rear sides of the second earphone body 20; the functional structure 23 may be located on the upper, lower, and front sides of the second earphone body 20; the functional structure 23 may be located on the upper, lower, and rear sides of the second earphone body 20; the functional structure 23 may be located on the upper, lower, and front sides of the second earphone body 20; the functional structure 23 may be located on the front, rear, and upper sides of the second earphone body 20; the functional structure 23 may be located on the front, rear, and lower sides of the second earphone body 20, etc.

[0078] The functional structure 23 includes a first microphone hole 221, which can be located on any one of the upper, lower, front, and rear sides of the housing 20a, so that the first microphone hole 221 will not be blocked by the user's ear, whether the earphone 200 is fitted to the left or right ear; the first microphone 230 can be used to pick up the user's voice during the call and the sound of the external environment through the first microphone hole 221.

[0079] In some embodiments, such as Figure 5 As shown, the second earphone body 20 may further include a second microphone 231, which may be disposed within the second earphone body 20. The second microphone 231 and the first microphone 230 may be spaced apart so that the second microphone 231 and the first microphone 230 can pick up different types of sound respectively. Furthermore, the second microphone 231 may be located on a second symmetry plane (O2-O2 plane) so that the second microphone 231 can have a similar sound pickup effect regardless of whether the earphone 200 is worn in the user's left or right ear.

[0080] like Figure 4As shown in Figure (b), the functional structure 23 also includes a second microphone hole 222. The second microphone hole 222 can be located on any one of the upper, lower, front, and rear sides of the housing 20a, so that the second microphone hole 222 will not be blocked by the user's ear, regardless of whether the earphone 200 is fitted to the left or right ear. The second microphone 231 can be used to pick up external ambient sounds through the second microphone hole 222. The second microphone hole 222 and the first microphone hole 221 can be spaced apart, and the first microphone hole 221 can be closer to the user's mouth relative to the second microphone hole 222, so that the first microphone 230 mainly picks up the user's voice during the call through the first microphone hole 221, and the second microphone 231 mainly performs noise reduction processing on the picked-up external ambient sounds, that is, it has an active noise reduction function, so as to reduce the interference of the user's voice and the external ambient sounds on the audio clarity. Of course, if it is necessary to pay attention to the external environment while listening to audio information, the second microphone 231 can be turned off, that is, the active noise reduction function can be turned off.

[0081] In some embodiments, as another implementation of functional structure 23, such as Figure 4 As shown in Figure (a), the functional structure 23 includes a first structure and a second structure. When the first structure is located on the first side 201 and the second structure is located on the second side 202, the second earphone body 20 also includes a first microphone 230. The first microphone 230 can be located inside the outer shell 20a and can be located on the second symmetry plane (O2-O2 plane) so that the sound pickup quality of the first microphone 230 can be ensured regardless of whether the earphone 200 is adapted to the left or right ear.

[0082] The first structure includes a third pickup hole 228, and the second structure includes a fourth pickup hole 232. The third pickup hole 228 can be located on the first side 201, and the fourth pickup hole 232 can be located on the second side 202. The third pickup hole 228 and the fourth pickup hole 232 can be symmetrically arranged about a second symmetry plane (O2-O2 plane). Wherein:

[0083] 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 fourth pickup hole 232. Since the second side 202 is close to the user's mouth at this time, the first microphone 230 is mainly used to pick up the user's voice through the fourth pickup hole 232 when the user is in a call.

[0084] 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 third microphone hole 228. Since the first side 201 is close to the user's mouth at this time, the third microphone hole 228 is mainly used to pick up the user's voice when the user is in a call.

[0085] In some embodiments, such as Figure 5 As shown, the second earphone body 20 may further include a second microphone 231, which may be disposed within the housing 20a. The second microphone 231 and the first microphone 230 may be spaced apart. Furthermore, the second microphone 231 may be located on a second symmetry plane (O2-O2 plane) so that the second microphone 231 can have a similar sound reception effect regardless of whether the earphone 200 is worn in the user's left or right ear.

[0086] like Figure 4 As shown in Figure (a), the first structure further includes a fifth microphone hole 237, and the second structure further includes a sixth microphone hole 238. The fifth microphone hole 237 can be located on the first side 201, and the sixth microphone hole 238 can be located on the second side 202. The fifth microphone hole 237 and the sixth microphone hole 238 can be symmetrically arranged about the second symmetry plane (O2-O2 plane). Furthermore, the third microphone hole 228 and the fourth microphone hole 232 are closer to the user's mouth than the fifth microphone hole 237 and the sixth microphone hole 238, so that the first microphone 230 mainly performs noise reduction processing on the picked-up external ambient sound through the third microphone hole 228 and the fourth microphone hole 232, that is, it has an active noise reduction function, so as to reduce the interference of the user's voice and the external ambient sound on the audio clarity. Of course, if it is necessary to pay attention to the external environment while listening to audio information, the second microphone 231 can be stopped, that is, the active noise reduction function can be turned off. Among them:

[0087] In the first posture, when the earphone 200 is worn on the user's left ear, the second microphone 231 can be used to pick up external ambient sounds through the sixth pickup hole 238 and perform active noise reduction on them; at the same time, the first side 201 is in close contact with the user's face, so that the fifth pickup hole 237 is blocked by the user's face, so that the external ambient sounds are basically picked up through the sixth pickup hole 238, effectively improving the reception quality of the external ambient sounds.

[0088] In the second posture, when the earphone 200 is worn on the user's right ear, the second microphone 231 can be used to pick up external sounds through the fifth pickup hole 237 and perform active noise reduction on them; at the same time, the second side 202 is in close contact with the user's face, so that the sixth pickup hole 238 is blocked by the user's face, so that the external ambient sound is basically picked up through the fifth pickup hole 237, effectively improving the reception quality of the external ambient sound.

[0089] In some embodiments, such as Figure 3As shown, the outer casing 20a includes a clamping portion 21 and an extension portion 22. The extension portion 22 can be connected to the clamping portion 21, and the connecting arm 30 can be connected to the clamping portion 21. The extension portion 22 may have a first end 227, and the functional structure 23 may be at least partially disposed at the first end 227. The first end 227 may be the end of the extension portion 22 away from the clamping portion 21, so that when the earphone 200 is in the wearing state, the functional structure 23 can be at least partially as close as possible to the user's mouth.

[0090] Optionally, such as Figure 4 As shown in Figure (b), when the functional structure 23 is located on at least one of the upper, lower, front, and rear sides of the second earphone body 20, the functional structure 23 includes a first pickup hole 221 and a second pickup hole 222. The first pickup hole 221 may be located at the first end 227, and the second pickup hole 222 may be located away from the first end 227 relative to the first pickup hole 221.

[0091] Or, such as Figure 4 As shown in Figure (a), when the functional structure 23 includes a first structure and a second structure, with the first structure located on the first side 201 and the second structure located on the second side 202, the first structure includes a third pickup hole 228 and a fifth pickup hole 237, and the second structure includes a fourth pickup hole 232 and a sixth pickup hole 238. The fifth pickup hole 237 and the sixth pickup hole 238 are located further away from the first end 227 than the third pickup hole 228 and the fourth pickup hole 232.

[0092] In some embodiments, such as Figure 3 As shown, the first earphone body 10 is movable relative to 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. Wherein:

[0093] 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 second earphone body 20 until the first earphone body 10 can be held in the concha cavity 102 of the user's left auricle 100, and the second earphone body 20 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 hold 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.

[0094] Combined with appendix Figure 4In 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 second earphone body 20 until the first earphone body 10 can be held in the concha cavity 102 of the user's right auricle 100, and the second earphone body 20 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 hold 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.

[0095] 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.

[0096] In some embodiments, such as Figure 4 As shown, the first earphone body 10 may have a first symmetry plane (O1-O1 plane), which may intersect with a second symmetry plane (O2-O2 plane). The outer surface of the first earphone body 10 may be symmetrical about the first symmetry plane (O1-O1 plane), and the outer surface of the connecting arm 30 may be symmetrical about the first symmetry plane (O1-O1 plane).

[0097] Understandably, the upper half of the outer surface of the first earphone body 10 and the connecting arm 30 in the first posture is located in the lower half of the second posture, and the lower half of the outer surface of the first earphone body 10 and the connecting arm 30 in the first posture is located in the upper half of the second posture. That is, the first earphone body 10 and the connecting arm 30 are in an up-down flipping relationship in the first posture and the second posture. Based on this, the symmetry of the outer surface of the first earphone body 10 and the outer surface of the connecting arm 30 about the first symmetry plane (O1-O1 plane) ensures that the wearing structure and wearing position relationship of the first earphone body 10 will not change whether it is in the first posture or the second posture. This ensures that the comfort and audio output quality of the earphone 200 will not differ whether it is worn in the left or right ear, and the fit of the left and right ears is further improved.

[0098] In some embodiments, such as Figure 4As 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.

[0099] 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.

[0100] In some embodiments, such as Figure 5 As shown, a switch 235 is provided inside the second earphone body 20. A button 236 may be provided on the rear, front, top, or bottom side of the second earphone body 20, and the button 236 is slidably disposed on the second earphone body 20. The button 236 may be positioned close to the switch 235 so that touching the button 236 can trigger the switch 235, enabling the earphone 200 to power on or off. Of course, the switch 235 can also be configured for other functions, such as adjusting the volume, pausing or playing audio files, answering or hanging up calls, and turning noise cancellation on or off.

[0101] Button 236 is positioned about the second symmetrical plane (O2-O2 plane) so that the user can touch button 236 to trigger switch 235 regardless of whether the earphone 200 is worn in the user's left or right ear.

[0102] It should be noted that if at least two buttons 236 are provided, and these two buttons 236 are located on the first side 201 and the second side 202 respectively, the functions of the buttons 236 on both sides can be the same. Based on this:

[0103] In the first posture, when the earphone 200 is worn on the user's left ear, the button 236 on the second side 202 faces away from the user's face, and the earphone 200 can be controlled by the button 236 on this side; at the same time, the button 236 on the first side 201 faces the user's face, and the button 236 on this side is in a stopped state (i.e., not working), which can effectively prevent accidental touch.

[0104] In the second posture, when the earphone 200 is worn on the user's left ear, the button 236 on the first side 201 faces away from the user's face, and the earphone 200 can be controlled by the button 236 on this side; at the same time, the button 236 on the second side 202 faces the user's face, and the button 236 on this side is in a stopped state (i.e., not working), which can effectively prevent accidental touch.

[0105] Optionally, button 236 may be a press-type button (e.g., mechanical button, membrane button), a touch-type button (e.g., capacitive touch button, inductive touch button), or a sensor-type button (e.g., optical button).

[0106] In some embodiments, such as Figure 4 As shown, the first earphone body 10 and connecting arm 30 in the first posture and the first earphone body 10 and connecting arm 30 in the second posture can be symmetrically arranged about the second symmetry plane (O2-O2 plane).

[0107] Understandably, when the first earphone body 10 and the connecting arm 30 are simultaneously located on the first side 201 or on the second side 202, their structure and function remain substantially unchanged. The only change is to adapt the first earphone body 10 and the connecting arm 30 to the user's left or right ear by mirroring their positions about the second symmetry plane (O2-O2 plane). 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 first or second posture. This further improves the fit of the earphone 200 when worn on the user's left and right ears.

[0108] Based on the aforementioned earphone 200, this utility model embodiment also provides an earphone, including a first earphone and a second earphone, wherein either or both of the first earphone and the second earphone can be the aforementioned earphone 200.

[0109] In some embodiments, as a configuration of a pair of headphones, the first earpiece can be the aforementioned earpiece 200, which can be adapted to the user's left and right ears; the second earpiece can be a regular earpiece, adapted to the user's left or right ear.

[0110] Understandably, if the second earphone is set to fit the user's right ear, when the user needs to wear a pair of earphones, the first earphone can be switched to the first position so that the first earphone fits the user's left ear. At this time, the first earphone and the second earphone can work together to form a pair of earphones that can be worn on the user's left and right ears at the same time.

[0111] When the user needs to wear the earbuds only in the left ear, the first earbud can be switched to the first position to fit the user's left ear, and the second earbud can be stored away. When the user needs to wear the earbuds only in the right ear, the first earbud can be switched to the second position to fit the user's right ear, and the second earbud can be stored away; alternatively, the second earbud can be used directly, and the first earbud can be stored away.

[0112] The same applies if the second earphone is set to fit the user's left ear, and will not be elaborated further here.

[0113] In some embodiments, as another configuration of a pair of headphones, both the first and second headphones in a pair of headphones can be the aforementioned headphones 200.

[0114] Understandably, when a user needs to wear a pair of headphones, one of the first and second headphones can be switched to the first position to fit the user's left ear, and the other can be switched to the second position to fit the user's right ear. At this time, the first and second headphones can work together to form a pair of headphones that can be worn on the user's left and right ears at the same time.

[0115] When a user needs to wear the earbuds only in their left ear, they can switch either the first or second earbud to the first position so that the first earbud fits the user's left ear, while the other earbud can be stored away. The same principle applies when a user needs to wear the earbuds only in their right ear, and will not be elaborated upon here.

[0116] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of the claims of the present invention.
