Description

Technical Field

[0001] This application relates to the field of smart device technology, and more particularly to an earphone and a wearable device. Background Technology

[0002] With the continuous improvement of living standards, various smart devices (such as headphones, mobile phones, and wearable devices) have become an indispensable part of people's work, study, and leisure. Among them, headphones are increasingly favored by consumers due to their high portability and small size. However, because in-ear headphones can easily cause ear discomfort after prolonged wear, such as ear canal pain and stuffiness, and may even have adverse effects on hearing, clip-on headphones are becoming increasingly popular. Furthermore, as consumers pursue a higher quality of life, their demands for headphone sound quality are also constantly increasing. However, because the sound quality of clip-on headphones is inferior to that of in-ear headphones, and due to their small size, the speakers in headphones can only be smaller in diameter. This results in a smaller speaker area, and the higher resonant frequency of small-diameter speakers can easily lead to poor low-frequency or bass performance. Utility Model Content

Detailed Implementation

[0074] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Unless otherwise stated, "a plurality of" means two or more.

[0079] Before explaining the technical solution of this application, the technical concept of this application will be explained first.

[0080] With the development of technology, modern technology and the environment have brought people a more exciting life, enriching their lifestyles and entertainment. Various smart devices (such as headphones, mobile phones, smartwatches, smart bracelets, and other wearable devices) are becoming increasingly common in people's work, study, and leisure activities. Among them, headphones are becoming increasingly popular due to their high portability and small size. Furthermore, as consumers pursue a higher quality of life, their demands for headphone comfort and sound quality are constantly increasing.

[0081] Headphones come in in-ear and open-back styles. However, in-ear headphones are increasingly popular because prolonged wear can cause ear discomfort such as ear canal pain and stuffiness, and may even negatively impact hearing. Open-back wireless headphones further include on-ear and clip-on styles, with clip-on headphones being particularly popular due to their smaller size, lighter weight, and portability. However, clip-on headphones generally have inferior sound quality compared to in-ear headphones. Furthermore, their smaller size limits the use of smaller speakers, resulting in a smaller speaker area. Additionally, smaller speakers have higher resonant frequencies, which can lead to poor low-frequency or bass response.

[0082] To solve the above problems, the inventors attempted to divide the inside of the headphone shell into an output cavity and a phase-inverting cavity using a speaker. The output cavity is located on the side where the front sound cavity of the speaker is located, and the phase-inverting cavity is located on the side where the rear sound cavity of the speaker is located. Two sound holes are opened on the headphone shell. One sound hole is connected to the output cavity and is used for sound output from the front sound cavity of the speaker. The other sound hole is connected to the phase-inverting cavity. The phase-inverting cavity is used to invert the phase of the sound waves generated by the rear sound cavity of the speaker, thereby changing the phase of the sound waves generated by the rear sound cavity of the speaker. This makes the phase of the sound waves consistent with or nearly consistent with the phase of the sound waves from the front sound cavity of the speaker. As a result, when the low-frequency sound waves from the front sound cavity of the speaker meet the low-frequency sound waves from the rear sound cavity of the speaker, a bass enhancement effect is produced. However, while a bass reflex cavity can enhance the low-frequency performance of headphones to some extent, the effect of bass reflex cavity alone is not ideal. Furthermore, the required bass reflex cavity occupies a relatively large volume, which makes it difficult to meet the miniaturization requirements of headphones, especially when headphones are stored in wearable devices such as watches, making it difficult to meet the requirement of a small overall size for headphones.

[0083] In view of this, embodiments of this application provide an earphone and a wearable device. A speaker component divides the internal space of the first housing into a first cavity and a second cavity. A bass reflex channel is provided in the second cavity, allowing the rear acoustic cavity of the speaker component to connect to a second sound outlet via the bass reflex channel. Through the bass reflex channel, the phase of the sound wave emitted from the rear acoustic cavity of the speaker component is changed, making the phase of the sound wave exiting the second sound outlet consistent with or nearly consistent with the phase of the sound wave exiting the first sound outlet. This causes the sound from the second sound outlet to superimpose with the sound from the first sound outlet, thereby enhancing the low-frequency effect of the earphone and improving the overall sound quality and clarity.

[0084] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0085] Please see Figures 1 to 5 , Figure 1 This is a schematic diagram of the structure of an earphone provided in an embodiment of this application; Figure 2 This is a cross-sectional view of an earphone provided in an embodiment of this application; Figure 3 This is an attached view of an earphone provided in an embodiment of this application; Figure 4 yes Figure 3 Sectional view at point AA; Figure 5 yes Figure 2 A partial enlarged view at point A. In a first aspect, embodiments of this application provide an earphone 100, which includes an earphone body 1. The earphone body 1 includes a first housing 11 and a speaker component 12. The first housing 11 is provided with a first sound outlet 1111 and a second sound outlet 1121 spaced apart. The speaker component 12 is disposed within the first housing 11, and the speaker component 12 divides the internal space of the first housing 11 into a first cavity 11a and a second cavity 11b. The front sound cavity of the speaker component 12 communicates with the first sound outlet 1111 through the first cavity 11a. The second cavity 11b forms a bass reflex channel K, and the rear sound cavity of the speaker component 12 communicates with the second sound outlet 1121 through the bass reflex channel K.

[0086] The earphone 100 provided in this embodiment divides the internal space of the first housing 11 into a first cavity 11a and a second cavity 11b by the speaker component 12. The rear acoustic cavity of the speaker component 12 is connected to the second sound outlet 1121 through the phase-inverting channel K in the second cavity 11b. Through the phase-inverting channel K, the phase of the sound wave emitted from the rear acoustic cavity of the speaker component 12 can be changed in the second cavity 11b, so that the phase of the sound wave coming out of the second sound outlet 1121 is consistent with or nearly consistent with the phase of the sound wave coming out of the first sound outlet 1111. This allows the sound coming out of the second sound outlet 1121 to superimpose with the sound coming out of the first sound outlet 1111, thereby enhancing the low-frequency effect of the earphone 100 and improving the overall sound quality and clarity of the earphone 100.

[0087] It is understandable that the low frequency mentioned above refers to the frequency of sound waves less than 1000Hz.

[0088] Furthermore, in this application, low frequency refers to the frequency of sound waves less than 300Hz.

[0089] Optionally, the material of the first housing 11 may include metal, plastic, plexiglass, etc., and this embodiment does not limit this. For example, if the first housing 11 is made of metal, the high mechanical strength and durability of metal allow the first housing 11 to withstand impacts, pressure, and wear, which helps protect the components inside the first housing 11. As another example, if the first housing 11 is made of plastic, the strong corrosion resistance of plastic prevents corrosion damage to the first housing 11 and its internal components; simultaneously, the light weight of plastic reduces the weight of the first housing 11, thus reducing the mass of the earphone 100. Yet another example, if the first housing 11 is made of plexiglass, the strong impact resistance and light weight of plexiglass contribute to the lightweight design of the first housing 11 and allow it to effectively resist impacts without easily breaking.

[0090] Optionally, the shape of the first housing 11 may include columnar, block-shaped, spherical, etc., and this embodiment is not limited thereto. To facilitate the description of the specific structure of the earphone 100, the following description will take the first housing 11 as a columnar shape as an example.

[0091] It is understood that the first housing 11 is generally cylindrical in shape. The first housing 11 has a wearing surface P along its own cylindrical height direction and a first surface M opposite to the wearing surface P. The wearing surface P is configured to be close to or in contact with the human ear 300 when the earphone body 1 is worn on the human ear 300. The outer peripheral surface of the first housing 11, the wearing surface P, and the first surface M together form the outer surface of the first housing 11. When the first housing 11 is cylindrical, the wearing surface P and the first surface M are two end faces along the extension direction of the first housing 11 (i.e., the cylindrical height direction).

[0092] Optionally, a dustproof screen can be installed at the first sound outlet 1111. The dustproof screen can effectively block dust and other impurities from the external environment from entering the sound outlet, which helps to avoid clogging of the sound outlet.

[0093] Optionally, a dustproof screen can be installed at the second sound outlet 1121. The dustproof screen can effectively block dust and other impurities from the external environment from entering the sound outlet, which helps to avoid clogging of the sound outlet.

[0094] Optionally, the aforementioned speaker component 12 may include, but is not limited to, an electrodynamic speaker, an electromagnetic speaker, a piezoelectric speaker, an electrostatic speaker, etc.

[0095] As an optional implementation method, such as Figure 4 and Figure 5As shown, the second cavity 11b also includes a bass reflex cavity G, which is connected to the rear acoustic cavity of the speaker component 12 and connected to the second sound outlet 1121 via a bass reflex channel K. The bass reflex cavity G extends the propagation distance of the sound waves emitted from the rear acoustic cavity of the speaker component 12, thereby better altering the phase of the sound waves emitted from the rear acoustic cavity of the speaker component 12, further enhancing the low-frequency effect of the headphones 100, and improving the overall sound quality and clarity of the headphones 100. Furthermore, the cooperation between the bass reflex cavity G and the bass reflex channel K reduces the volume of the second cavity 11b required to enhance the low-frequency effect of the headphones 100, which is beneficial for the miniaturization of the headphones 100.

[0096] Please combine Figure 6 , Figure 6 This is a partial disassembly diagram of the main body of an earphone provided in an embodiment of this application. In some optional embodiments, the propagation distance of the sound waves emitted from the rear acoustic cavity of the speaker component 12 can be extended by designing the positions of the second sound outlet 1121, the rear sound outlet 12a of the rear acoustic cavity of the speaker component 12, and the third sound outlet K1 of the bass reflex cavity G that communicates with the bass reflex channel K, as detailed below:

[0097] Optionally, such as Figures 4 to 6 As shown, the rear sound cavity of the speaker component 12 has a rear sound outlet 12a, which is connected to the phase inversion channel K through the phase inversion cavity G. The phase inversion cavity G has a third sound outlet K1 connected to the phase inversion channel K. The projection of the rear sound outlet 12a on a plane perpendicular to the thickness direction of the speaker component 12 is spaced apart from the projection of the third sound outlet K1 on a plane perpendicular to the thickness direction of the speaker component 12.

[0098] Optionally, the phase reversing cavity G has a third sound outlet K1 that communicates with the phase reversing channel K. The projection of the third sound outlet K1 onto a plane perpendicular to the thickness direction of the speaker component 12 is spaced apart from the projection of the second sound outlet 1121 onto a plane perpendicular to the thickness direction of the speaker component 12.

[0099] Optionally, the rear acoustic cavity of the speaker component 12 has a rear sound outlet 12a, which is connected to the phase inversion channel K through the phase inversion cavity G. The phase inversion cavity G has a third sound outlet K1 connected to the phase inversion channel K. The projection of the rear sound outlet 12a onto a plane perpendicular to the thickness direction of the speaker component 12 is spaced apart from the projection of the third sound outlet K1 onto a plane perpendicular to the thickness direction of the speaker component 12. The projection of the third sound outlet K1 onto a plane perpendicular to the thickness direction of the speaker component 12 is spaced apart from the projection of the second sound outlet 1121 onto a plane perpendicular to the thickness direction of the speaker component 12.

[0100] Compared to the method where the rear sound outlet 12a, the second sound outlet 1121, and the third sound outlet K1 are directly connected along the thickness direction of the speaker component 12, the above method effectively extends the propagation distance of the sound waves emitted from the rear sound cavity of the speaker component 12. This avoids the situation where the sound waves emitted from the rear sound cavity of the speaker component 12 are directly propagated to the external environment along the thickness direction of the speaker component 12 through the second sound outlet 1121. This allows for a better modification of the phase of the sound waves emitted from the rear sound cavity of the speaker component 12, thereby further enhancing the low-frequency effect of the headphones 100 and improving the overall sound quality and clarity of the headphones 100. Furthermore, this method allows for a smaller volume of the second cavity 11b required to enhance the low-frequency effect of the headphones 100, which is beneficial for the miniaturization of the headphones 100.

[0101] It is understandable that the projection of the rear sound outlet 12a onto a plane perpendicular to the thickness direction of the speaker component 12 and the projection of the third sound outlet K1 onto a plane perpendicular to the thickness direction of the speaker component 12 are spaced apart. This can be because the projection of the rear sound outlet 12a onto a plane perpendicular to the thickness direction of the speaker component 12 and the projection of the third sound outlet K1 onto a plane perpendicular to the thickness direction of the speaker component 12 are located on the same side of the speaker component 12 and spaced apart; or it can be because the projection of the rear sound outlet 12a onto a plane perpendicular to the thickness direction of the speaker component 12 and the projection of the third sound outlet K1 onto a plane perpendicular to the thickness direction of the speaker component 12 are located on opposite sides of the speaker component 12 and spaced apart.

[0102] It is understandable that the projection of the third sound outlet K1 onto the plane perpendicular to the thickness direction of the speaker component 12 and the projection of the second sound outlet 1121 onto the plane perpendicular to the thickness direction of the speaker component 12 are spaced apart. This can be because the projection of the third sound outlet K1 onto the plane perpendicular to the thickness direction of the speaker component 12 and the projection of the second sound outlet 1121 onto the plane perpendicular to the thickness direction of the speaker component 12 are located on the same side of the speaker component 12 and spaced apart; or it can be because the projection of the third sound outlet K1 onto the plane perpendicular to the thickness direction of the speaker component 12 and the projection of the second sound outlet 1121 onto the plane perpendicular to the thickness direction of the speaker component 12 are located on opposite sides of the speaker component 12 and spaced apart.

[0103] Optionally, such as Figure 5 and Figure 6As shown, the rear sound outlet 12a and the third sound outlet K1 are located on opposite sides of the speaker component 12. This further extends the propagation distance of the sound waves emitted from the rear acoustic cavity of the speaker component 12, thereby better altering the phase of the sound waves emitted from the rear acoustic cavity of the speaker component 12, and further enhancing the low-frequency effect of the headphones 100, which is beneficial for improving the overall sound quality and clarity of the headphones 100. Furthermore, it allows for a smaller volume of the second cavity 11b required to achieve the enhanced low-frequency effect of the headphones 100, which is beneficial for further miniaturization of the headphones 100.

[0104] Optionally, the volume of the bass reflex cavity G is larger than the volume of the bass reflex channel K. In this way, the sound waves emitted from the rear acoustic cavity of the speaker component 12 are compressed and their phase altered during transmission through the bass reflex cavity G to the bass reflex channel K. This increases the sound pressure level of the sound waves entering the bass reflex channel K, thereby increasing the loudness of the sound in the bass reflex channel K. This enhances the low-frequency performance of the headphones 100, and consequently improves the overall sound quality and clarity of the headphones 100.

[0105] Optionally, such as Figure 5 and Figure 6 As shown, the first housing 11 includes a first sub-housing 111 and a second sub-housing 112. The first sub-housing 111 and the second sub-housing 112 are connected to form a cavity. The speaker component 12 is disposed in the cavity to divide the cavity into a first cavity 11a and a second cavity 11b. A first sound outlet is opened on the first sub-housing 111, and a second sound outlet is opened on the second sub-housing 112. A first blocking member 31 is disposed in the second sub-housing 112. The first blocking member 31 is located on the side where the rear sound cavity of the speaker component 12 is located. A phase reversal cavity G is formed between the first blocking member 31, the second sub-housing 112 and the speaker component 12. A phase reversal channel K is formed between the side of the first blocking member 31 away from the speaker component 12 and the second sub-housing 112. The method of forming the bass reflex cavity G and bass reflex channel K by enclosing the space between the second sub-shell 112, the speaker component 12, and the first barrier 31 enhances the overall structural compactness of the headphone 100 and facilitates the arrangement of the bass reflex cavity G and the bass reflex channel K. Furthermore, by configuring the first shell 11 as a first sub-shell 111 and a second sub-shell 112, the installation of components such as the speaker component 12 within the first shell 11 can be facilitated without requiring complex procedures, thus simplifying the manufacturing process of the headphone 100 and improving its production efficiency.

[0106] Optionally, the first barrier 31 may include, but is not limited to, a metal sheet, a plastic sheet, etc.

[0107] Please combine Figure 7 , Figure 7 This is a schematic diagram of the structure of the cover portion of an earphone according to an embodiment of this application. Optionally, as... Figure 5 and Figure 7 As shown, the second sub-shell 112 includes an outer shell portion 112a and a cover portion 112b. The outer shell portion 112a is connected to the first sub-shell 111. The outer shell portion 112a has an opening at one end away from the first sub-shell 111. The cover portion 112b is connected to the outer shell portion 112a to cover the opening of the outer shell portion 112a. A first barrier 31 is connected to the outer shell portion 112a and the cover portion 112b. A phase reversal cavity G is formed between the first barrier 31, the outer shell portion 112a and the speaker component 12. At least one of the cover portion 112b and the first barrier 31 is provided with a protrusion H that abuts against the other. The protrusion H is configured to separate the space between the cover portion 112b and the first barrier 31 to form a phase reversal channel K.

[0108] It is understood that at least one of the cover portion 112b and the first barrier member 31 is provided with a protrusion H that abuts against the other. This could be that the cover portion 112b is provided with a protrusion H that abuts against the first barrier member 31; or that the first barrier member 31 is provided with a protrusion H that abuts against the cover portion 112b; or that the cover portion 112b is provided with a protrusion H, the first barrier member 31 is also provided with a protrusion H, and the protrusion H of the cover portion 112b abuts against the protrusion H of the first barrier member 31, etc. This embodiment does not limit this.

[0109] By using a protrusion H on the cover portion 112b and the first barrier 31 to form the phase inversion channel K, the setting of the phase inversion channel K can be simplified. Furthermore, the setting position of the phase inversion channel K does not need to be adjusted during assembly, which is beneficial to simplifying the manufacturing process of the earphone 100 and thus facilitating the mass production of the earphone 100.

[0110] Optionally, the protrusion H can be integrally formed on the first barrier 31 or the cover portion 112b, thereby simplifying the structural assembly of the earphone 100 and thus reducing the assembly difficulty of the earphone 100.

[0111] Optionally, the bass reflex cavity G has a third sound outlet K1 communicating with the bass reflex channel K. The second sound outlet 1121 is disposed on the cover portion 112b, and the projection of the third sound outlet K1 on the cover portion 112b is spaced apart from the second sound outlet 1121. Using this method, compared to the direct communication between the second sound outlet 1121 and the third sound outlet K1 along the thickness direction of the speaker component 12, it effectively extends the propagation distance of the sound waves emitted from the rear acoustic cavity of the speaker component 12. This avoids the situation where the sound waves emitted from the rear acoustic cavity of the speaker component 12 are directly propagated to the external environment along the thickness direction of the speaker component 12 through the second sound outlet 1121. This allows for better modification of the phase of the sound waves emitted from the rear acoustic cavity of the speaker component 12, thereby further enhancing the low-frequency effect of the headphones 100 and improving the overall sound quality and clarity of the headphones 100. Furthermore, the volume of the second cavity 11b required to enhance the low-frequency effect of the headphones 100 is smaller, which is beneficial for the miniaturization of the headphones 100. In addition, by placing the second sound outlet 1121 on the cover portion 112b, compared to placing the second sound outlet 1121 on the outer shell portion 112a, the second sound outlet 1121 can have a larger opening area, which is beneficial for improving the sound output effect of the headphones 100, and thus improving the wearer's auditory experience and user experience.

[0112] Optionally, such as Figure 7As shown, the protrusion H includes a first sub-protrusion H1, a second sub-protrusion H2, and a third sub-protrusion H3. The first sub-protrusion H1 is located near the third sound outlet K1. The second sub-protrusion H2 is located on the side of the first sub-protrusion H1 away from the third sound outlet K1. The third sub-protrusion H3 is connected to the second sub-protrusion H2. The projection of the third sound outlet K1 on the cover portion 112b and the second sound outlet 1121 are located on opposite sides of the third sub-protrusion H3. The space between the first barrier 31 and the cover portion 112b is divided into an S-shaped phase-reversing channel K by the first sub-protrusion H1, the second sub-protrusion H2, and the third sub-protrusion H3. This further extends the transmission distance of the sound waves emitted from the rear acoustic cavity of the speaker component 12, thereby better changing the phase of the sound waves emitted from the rear acoustic cavity of the speaker component 12, and further enhancing the low-frequency effect of the headphones 100, which is beneficial to improving the overall sound quality and clarity of the headphones 100. Furthermore, it allows for a smaller volume of the second cavity 11b required to enhance the low-frequency effect of the headphones 100, which is beneficial for the miniaturization of the headphones 100. Of course, it is understood that in addition to including the first sub-protrusion H1, the second sub-protrusion H2, and the third sub-protrusion H3 to form an S-shaped phase-reversing channel, the protrusion H can also form, for example, Z-shaped, N-shaped, or M-shaped phase-reversing channels. For example, when the protrusion is formed as a Z-shaped phase inversion channel, the protrusion H may include a first sub-protrusion H1 and a second sub-protrusion H2. The first sub-protrusion H1 and the second sub-protrusion H2 are sequentially spaced between the third sound outlet K1 and the second sound outlet 1121, and the first sub-protrusion H1 and the second sub-protrusion H2 extend to opposite sides of the cover portion 112b, respectively. For example, when the protrusion is formed as an M-shaped phase inversion channel, the protrusion H may include three V-shaped first sub-protrusion H1, second sub-protrusion H2, and third sub-protrusion H3. The first sub-protrusion H1, second sub-protrusion H2, and third sub-protrusion H3 are sequentially spaced between the third sound outlet K1 and the second sound outlet 1121. The openings of the first sub-protrusion H1 and the third sub-protrusion H3 have the same orientation, and the opening orientation of the second sub-protrusion H2 is opposite to that of the first sub-protrusion H1.

[0113] Optionally, when the cover portion 112b is provided with a protrusion H and the first barrier member 31 is also provided with a protrusion H, it is possible that a portion of the first sub-protrusion H1, the second sub-protrusion H2, and the third sub-protrusion H3 are provided on the cover portion 112b, and the other portion is provided on the first barrier member 31; it is also possible that the cover portion 112b is provided with the first sub-protrusion H1, the second sub-protrusion H2, and the third sub-protrusion H3, and the first barrier member 31 is also provided with the first sub-protrusion H1, the second sub-protrusion H2, and the third sub-protrusion H3, etc., this embodiment does not limit this.

[0114] As an optional implementation method, such as Figure 5 As shown, the main body of the earphone 100 also includes a battery 13, which is disposed within the first cavity 11a. The battery 13 is electrically connected to the speaker component 12. Along the thickness direction of the speaker component 12, the first sound outlet 1111 is located between the speaker component 12 and the battery 13. In this manner, when the earphone 100 is worn on the human ear 300, the battery 13 is closer to the wearing surface P. On the one hand, this makes the center of gravity of the earphone 100 closer to the human ear 300, preventing the earphone 100 from flipping outwards due to gravity on the side furthest from the human ear 300, thus improving the wearing stability of the earphone 100. On the other hand, it allows the first sound outlet 1111 to be better aligned with the ear canal of the human ear 300 when the earphone 100 is worn, thereby improving the sound output effect of the earphone 100. Furthermore, compared to placing the speaker component 12 closer to the wearing surface P, this method allows the speaker component 12 to be placed away from the auricle of the human ear 300, thus freeing it from the limitations of the auricle size. This allows for the selection of a larger speaker component 12, which in turn provides better sound quality and improves the sound quality of the headphones 100.

[0115] Optionally, the projection of the battery 13 onto a plane perpendicular to the thickness direction of the speaker component 12 is located within the projection range of the speaker component 12 onto the same plane. This approach allows the speaker component 12 to have a larger size, resulting in better sound quality and thus improving the sound quality of the headphones 100. Furthermore, because the battery 13 is smaller near the wearing surface P, the end of the headphone body 1 closest to the wearing surface P is smaller, allowing the headphone body 1 to better fit the concha of the human ear 300 and preventing pressure on the concha, thus improving the wearing comfort of the headphones 100.

[0116] Optionally, such as Figure 5 As shown, the main body of the earphone 100 also includes a second barrier 32, which is disposed within the first cavity 11a. Along the thickness direction of the speaker component 12, the second barrier 32 is located between the first sound outlet 1111 and the battery 13. The second barrier 32 serves two purposes: firstly, it blocks sound waves emitted from the front sound cavity of the speaker component 12, preventing them from reaching the location of the battery 13. Secondly, it prevents dust, liquids, and other external particles from entering the location of the battery 13 through the first sound outlet 1111, thus protecting the battery 13 and preventing corrosion.

[0117] Optionally, the second barrier 32 may include, but is not limited to, a metal sheet, a plastic sheet, etc.

[0118] Optionally, such as Figure 5 As shown, the second barrier 32 includes a first part 321 and a second part 322. The first part 321 is connected to the second part 322. Along the thickness direction of the speaker component 12, the first part 321 and the second part 322 are spaced apart. The first part 321 is located between the speaker component 12 and the second part 322, and the second part 322 is located between the first sound outlet 1111 and the first part 321. The connection between the first part 321 and the second part 322 is an arc-shaped transition. In this way, the height difference between the first part 321 and the second part 322 provides space for the battery 13 to lay out its wiring, and also makes it easier for the sound waves emitted by the front sound cavity of the speaker component 12 to be reflected by the second barrier 32 and transmitted out from the first sound outlet 1111.

[0119] It is understandable that the second barrier 32, in addition to including the first part 321 and the second part 322 mentioned above, can also be a flat plate, a curved plate, etc.

[0120] Please see Figures 8 to 11 , Figure 8 This is a schematic diagram of the structure of an earphone (showing the angle between the inclined section and the straight section) provided in an embodiment of this application; Figure 9 This is a schematic diagram of the structure of an earphone (in a wearing state) provided in an embodiment of this application; Figure 10 This is a structural schematic diagram of an earphone worn on a human ear from one perspective, according to an embodiment of this application. Figure 11 This is a structural schematic diagram of an earphone worn on a human ear, provided in an embodiment of this application, from another perspective. Furthermore, considering the wearing stability of the earphone 100, this application also designs a solution to improve the wearing stability of the earphone body 1, as detailed below:

[0121] Some alternative implementations, such as Figures 8 to 11 As shown, the earphone 100 includes a clamping portion 2 connected to a first housing 11. The clamping portion 2 and the first housing 11 form a clamping space for clamping onto a human ear 300, allowing the earphone body 1 to be worn on the human ear 300. This application utilizes the clamping effect of the clamping space formed between the clamping portion 2 and the first housing 11 to ensure the earphone body 1 is worn on the human ear 300, thus making the earphone 100 an ear-clip type earphone. This improves the wearing stability of the earphone body 1, helps prevent the earphone body 1 from loosening during wear and reducing the wearer's auditory experience, and ultimately enhances the user experience.

[0122] Some alternative implementations, such as Figures 8 to 11 As shown, the clamping part 2 includes a connecting arm 21 and a clamping arm 22. One end of the connecting arm 21 is connected to the first housing 11, and the clamping arm 22 is connected to the other end of the connecting arm 21. The clamping arm 22 and the connecting arm 21 can form a clamping space with the first housing 11 for clamping onto the human ear 300, so that the earphone body 1 can be worn on the human ear 300. Since the clamping arm 22 and the connecting arm 21 can form a clamping space with the first housing 11 for clamping onto the human ear 300, the earphone body 1 can be worn through the clamping arm 22.

[0123] Optionally, the host body, connecting arm, and clamping arm forming the clamping space may include:

[0124] In one example, the main body and the clamping arm are respectively connected to the two ends of the connecting arm along its length, and the main body and the clamping arm are set at an angle to the connecting arm, so that the three form the clamping space, which is roughly adapted to the human ear to clamp onto the human ear.

[0125] Or, in another example, such as Figures 8 to 11 As shown, the clamping arm 22 is rotatably connected to the connecting arm 21. The clamping arm 22 can rotate relative to the connecting arm 21 to change the opening angle θ between the clamping arm 22 and the connecting arm 21. Because the clamping arm 22 can rotate relative to the connecting arm 21 to adjust the opening angle θ between the clamping arm 22 and the connecting arm 21, the wearer can adjust the appropriate opening angle θ between the clamping arm 22 and the connecting arm 21 according to their own ear shape. This avoids the occurrence of excessive or insufficient clamping force of the earphone 100, which helps to reduce the discomfort such as foreign body sensation and pain when wearing the earphone 100. This helps to increase the wearing enthusiasm of wearers, especially the elderly who have a resistance to wearing the earphone 100.

[0126] Optionally, such as Figure 8 As shown, to enable rotation between the clamping arm and the connecting arm, the earphone 100 also includes a connector 6. The connector 6 connects the connecting arm 21 and the clamping arm 22. The connector 6 is configured to allow the clamping arm 22 to rotate relative to the connecting arm 21, thereby changing the opening angle θ between the clamping arm 22 and the connecting arm 21. Through the connector 6, on the one hand, the clamping arm 22 can be rotatably connected to the connecting arm 21; on the other hand, the opening angle θ between the clamping arm 22 and the connecting arm 21 can be maintained, allowing the earphone body 1 to be worn on the human ear 300.

[0127] Optionally, such as Figure 8As shown, the connector 6 includes a pivot 61 or an elastic element. When the connector 6 includes an elastic element, the elastic element is configured to bend and deform to change the opening angle θ between the clamping arm 22 and the connecting arm 21. In this way, the clamping arm 22 can be rotatably connected to the connecting arm 21 via the pivot 61 or the elastic element. Furthermore, the pivot 61 allows for better rotation of the clamping arm 22, thereby adjusting the opening angle θ between the clamping arm 22 and the connecting arm 21.

[0128] Optionally, the aforementioned rotating shaft 61 may include a single-cell structure damping rotating shaft, a spring-loaded damping rotating shaft, an overlapping damping rotating shaft, etc., and this embodiment does not limit this type. By setting the rotating shaft 61 as a damping rotating shaft, both the rotation of the clamping arm 22 relative to the connecting arm 21 and the maintenance of the angle between the clamping arm 22 and the connecting arm 21 can be achieved. In addition, the damping rotating shaft method simplifies the way the clamping arm 22 can rotate relative to the connecting arm 21, which helps to simplify the manufacturing process of the earphone 100 and thus improve the production efficiency of the earphone 100.

[0129] Optionally, the above-mentioned elastic element includes shape memory metal sheet, soft rubber sheet, spring sheet, etc., and this embodiment does not limit it.

[0130] Optionally, the angle at which the clamping arm 22 can rotate relative to the connecting arm 21 is 0°-160°, that is, the opening and closing angle θ between the clamping arm 22 and the connecting arm 21 is 0°-160°. By setting the range of the angle at which the clamping arm 22 can rotate relative to the connecting arm 21, the distance between the end of the clamping arm 22 away from the connecting arm 21 and the wearing surface P of the earphone body 1 can be smaller, thereby enabling the earphone 100 to adapt to the ear contour size of more people and improving the applicability of the earphone 100 to different groups of people.

[0131] It is understood that the angle at which the clamping arm 22 can rotate relative to the connecting arm 21 is 0°-160°, and can be, for example, 0°, 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, 90°, 95°, 100°, 105°, 110°, 115°, 120°, 125°, 130°, 135°, 140°, 145°, 150°, 155°, 160°, etc. This embodiment does not limit this.

[0132] As an optional implementation method, such as Figure 8 and Figure 9As shown, a concave surface 221 is provided on the side surface of the clamping arm 22 near the headphone body 1. The concave surface 221 on the side surface of the clamping arm 22 can increase the rotation angle of the clamping arm 22 relative to the connecting arm 21, which is beneficial to increasing the angle range between the clamping arm 22 and the connecting arm 21. This allows the distance between the end of the clamping arm 22 away from the connecting arm 21 and the wearing surface P of the headphone body 1 to be smaller, thereby enabling the headphone 100 to adapt to the ear contour size of more people and improving the applicability of the headphone 100 to different groups of people.

[0133] Optionally, such as Figure 8 As shown, the connecting arm 21 includes a second housing 21a, which includes an inclined section 211 and a straight section 212. One end of the inclined section 211 is connected to the first housing 11, and the straight section 212 is connected to the other end of the inclined section 211. The straight section 212 and the inclined section 211 are set at an angle. The clamping arm 22 is rotatably connected to the end of the straight section 212 away from the inclined section 211. Considering that the inclined section 211 will slightly sag under gravity after the earphone 100 is worn, this application sets the inclined section 211 and the straight section 212 at an angle, so that the inclined section 211 can be closer to the human ear 300, and can fit more snugly with the human ear 300 when the inclined section 211 sags (e.g., when the earphone 100 is worn). Figure 10 and Figure 11 As shown in the diagram, the space formed by the inclined section 211, the straight section 212, and the clamping arm 22 provides a better fit for the human ear 300, thus preventing the earphone body 1 from becoming loose during wear. This improves the wearing comfort of the earphone 100 and enhances the user experience. Furthermore, the clamping arm 22 allows adjustment of the opening angle θ between the clamping arm 22 and the straight section 212, enabling the earphone 100 to be stored in the charging case. This saves space in the charging case and improves its space utilization. In particular, when the earphone 100 is plugged into a wearable device, it facilitates the miniaturization of the wearable device.

[0134] Furthermore, by adopting this method, since the clamping arm 22 can rotate relative to the straight section 212 to adjust the opening angle θ between the clamping arm 22 and the straight section 212, the wearer can adjust the appropriate opening angle θ between the clamping arm 22 and the straight section 212 according to the shape of their auricle. This can avoid the occurrence of excessive or insufficient clamping force of the earphone 100, which helps to reduce the discomfort such as foreign body sensation and pain when wearing the earphone 100. This is conducive to increasing the wearing enthusiasm of wearers, especially the elderly who have a resistance to wearing the earphone 100.

[0135] It is understood that the materials of the second housing 21a mentioned above also include metal, plastic, plexiglass, etc., and this embodiment will not elaborate on this further.

[0136] It is understood that the materials of the first housing 11 and the second housing 21a may be the same or different, and this embodiment does not limit this.

[0137] Optionally, such as Figure 8 As shown, at the connection between the straight section 212 and the inclined section 211, a first included angle α is formed between the straight section 212 and the inclined section 211, with the first included angle α being 90°-180°. Through the obtuse first included angle α, when the earphone body 1 is worn on the human ear 300, the straight section 212 and the inclined section 211 can be closer to the human ear 300. This allows the space formed by the inclined section 211, the straight section 212, and the clamping arm 22 to have a better wrapping effect on the human ear 300, thereby preventing the earphone body 1 from becoming loose during wear. This improves the wearing comfort of the earphone 100 and enhances the user experience.

[0138] It is understood that the first included angle α mentioned above is 90°-180°, and can be, for example, 95°, 100°, 105°, 110°, 115°, 120°, 125°, 130°, 135°, 140°, 145°, 150°, 155°, 160°, 165°, 170°, 175°, 180°, 185°, etc. This embodiment does not limit this.

[0139] Optionally, the first included angle α, which is 90°-180°, can be: 90°-180°; 95°-180°; 100°-180°; 105°-180°; 110°-180°; 115°-180°; 120°-180°; 125°-180°; 130°-180°; 135°-180°; 140°-180°; 140°-175°; or 140°-170°. Alternatively, the first included angle α is 140°-165°. Alternatively, the first included angle α is 140°-160°. Alternatively, the first included angle α is 145°-160°. Alternatively, the first included angle α is 145°-155°. Alternatively, the first included angle α is 145°-150°, etc., and this embodiment does not limit this.

[0140] Optionally, such as Figure 8As shown, the first housing 11 has a wearing surface P and a first surface M opposite to the wearing surface P. The wearing surface P is configured to be close to or in contact with the human ear 300 when the earphone body 1 is worn on the human ear 300. The inclined section 211 has a second surface N opposite to the wearing surface P, and the second surface N is set at an angle to the first surface M. By setting the second surface N of the inclined section 211 at an angle to the first surface M of the earphone body 1, the inclined section 211 can be closer to the human ear 300 when the earphone body 1 is worn on the human ear 300. Furthermore, the inclined section 211 can fit more snugly to the human ear 300 when the straight section 212 is slightly lowered. This results in a better wrapping effect of the space formed by the inclined section 211, the straight section 212, and the clamping arm 22 on the human ear 300, thereby preventing the earphone body 1 from becoming loose during wear. This improves the wearing comfort of the earphone 100 and enhances the user experience.

[0141] Optionally, such as Figure 8 As shown, a second included angle β is formed between the first surface M and the second surface N (for ease of labeling, the reference numerals for the second included angle β in the figures of this application are all shown at their apex angles), and the supplementary angle of the second included angle β is an acute angle. By setting the second included angle β as an obtuse angle, the inclined segment 211 and the straight segment 212 can better conform to the contour of the human ear 300, thereby providing a better wrapping effect on the human ear 300 within the space formed by the inclined segment 211, the straight segment 212, and the clamping arm 22. This is beneficial for improving the wearing stability of the earphone 100, and thus for improving the wearing comfort of the earphone 100 and the user experience.

[0142] Optionally, the supplementary angle of the second included angle β can be 20°-90°. In this way, the space formed by the inclined segment 211 and the straight segment 212 can be further improved to enhance the wrapping effect on the human ear 300, which is conducive to further improving the wearing stability of the earphone 100, and thus further improving the wearing comfort of the earphone 100 and the user experience.

[0143] It is understood that the supplementary angle of the second included angle β is 20°-90°, and can be, for example, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, etc. This embodiment does not limit this.

[0144] Optionally, the supplementary angle of the second included angle β is 20°-90°, which can be: 20°-90°; 25°-90°; 30°-90°; 35°-90°; 40°-90°; 45°-90°; 45°-85°; 45°-80°; 45°-75°; 45°-70°; 45°-65°; or 45°-60°. Alternatively, the supplementary angle of the second included angle β is 45°-55°. Alternatively, the supplementary angle of the second included angle β is 45°-50°, etc., but this embodiment does not limit it.

[0145] As an optional implementation method, such as Figure 8 As shown, the first housing 11 is cylindrical and extends along the extension direction X of the straight section. This allows the earphone 100 to be directly inserted into the charging case along the extension direction X of the straight section when stored inside, facilitating storage and saving space in the charging case, thus improving its space utilization. In particular, when the earphone 100 is plugged into a wearable device, it contributes to the miniaturization of the wearable device.

[0146] It is understandable that the thickness direction of the aforementioned speaker component 12 is the same as the extension direction X of the straight section.

[0147] Optionally, such as Figure 8 As shown, the minimum distance D between the outer peripheral surface of the first housing 11 and the outer peripheral surface of the straight section 212 is 3mm-8mm. By setting the range of the minimum distance D between the outer peripheral surface of the first housing 11 and the outer peripheral surface of the straight section 212, the straight section 212 can be made closer to the human ear 300 when worn, thereby further improving the wrapping effect of the space formed by the inclined section 211, the straight section 212 and the clamping arm 22 on the human ear 300, which is conducive to further improving the wearing stability of the earphone 100, and thus further improving the wearing comfort of the earphone 100 and the user experience.

[0148] Optionally, the minimum distance D between the outer peripheral surface of the first housing 11 and the outer peripheral surface of the straight section 212 is 3mm-8mm, and can be, for example, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, etc. The embodiments of this application do not limit this.

[0149] Optionally, the minimum distance D between the outer peripheral surface of the first housing 11 and the outer peripheral surface of the straight section 212 is 3mm-8mm. Specifically, it can be 3.5mm-8mm, 4mm-8mm, 4mm-7.5mm, 4mm-7mm, or 4mm-6.5mm. Alternatively, the minimum distance D between the outer peripheral surface of the first housing 11 and the outer peripheral surface of the straight section 212 may be 4mm-6mm. Alternatively, the minimum distance D between the outer peripheral surface of the first housing 11 and the outer peripheral surface of the straight section 212 may be 4mm-5.5mm. Alternatively, the minimum distance D between the outer peripheral surface of the first housing 11 and the outer peripheral surface of the straight section 212 may be 4mm-5mm. Alternatively, the minimum distance D between the outer peripheral surface of the first housing 11 and the outer peripheral surface of the straight section 212 may be 4mm-4.5mm, etc., and this embodiment does not limit this.

[0150] Please see Figures 12 to 14 , Figure 12 yes Figure 8 A magnified view of a section at point B in the middle; Figure 13 This is a schematic diagram of the circuit board structure of an earphone provided in an embodiment of this application; Figure 14 yes Figure 13 A schematic diagram of the unfolded circuit board structure is shown. To improve the space utilization and miniaturization of the earphone 100, this application also designs the stacking of electronic components such as the circuit board 23 and microphone 24 of the earphone 100, as detailed below:

[0151] As an optional implementation method, such as Figures 12 to 14As shown, the second housing 21a has a sound receiving hole 213, and a mounting cavity 214 is formed inside the second housing 21a. The mounting cavity 214 communicates with the sound receiving hole 213. A circuit board 23 and a microphone 24 are disposed in the mounting cavity 214. The microphone 24 is electrically connected to the circuit board 23 and is positioned corresponding to the sound receiving hole 213. By utilizing the internal space of the second housing 21a of the connecting arm 21 and stacking electronic components such as the circuit board 23 and the microphone 24 within the internal space of the second housing 21a, the space utilization rate of the connecting arm 21 is improved, which in turn improves the space utilization rate of the headphones 100. Furthermore, by placing the microphone 24 inside the second housing 21a, it can be positioned away from the first sound outlet 1111 and the second sound outlet 1121, thereby avoiding interference from the sound output of the speaker component 12 and improving the sound pickup effect of the microphone 24.

[0152] Optionally, such as Figures 12 to 14 As shown, the circuit board 23 includes a first rigid board 231, a second rigid board 232, and a first flexible board 233. The first rigid board 231 is disposed inside the inclined section 211, and the second rigid board 232 is disposed inside the straight section 212. One end of the first flexible board 233 is connected to the first rigid board 231, and the other end of the first flexible board 233 is connected to the second rigid board 232. The first flexible board 233 is electrically connected to the first rigid board 231 and the second rigid board 232. The combination of rigid and flexible circuit board 23 allows for better arrangement of the circuit board 23 and the microphone 24 within the internal spaces of the straight section 212 and the inclined section 211 of the second housing 21a, which helps to further improve the space utilization of the connecting arm 21, thereby further improving the space utilization of the earphone 100.

[0153] Optionally, the microphones 24 described above may include multiple microphones, which are positioned remotely from each other. For example, such as... Figures 12 to 14 As shown, the microphone 24 includes two microphones. One microphone 24 is located within the inclined section 211 near the end of the earphone body 1, and the other microphone 24 is located within the straight section 212 near the end of the clamping arm 22. By distancing the multiple microphones 24 from each other, on the one hand, the sound wave intensity of the microphones 24 at different positions varies, thereby improving the noise reduction effect of the earphone 100; on the other hand, distancing the multiple microphones 24 from each other reduces signal interference between the microphones 24, which is beneficial to improving the sound pickup effect of the microphones 24. In addition, by setting multiple microphones 24, some microphones 24 can be used to enable the earphone 100 to perform call functions, while others can be used to enable the earphone 100 to perform hearing assistance functions, thereby providing hearing assistance to elderly people who may have hearing impairments.

[0154] Optionally, such as Figures 12 to 14As shown, the circuit board 23 also includes a second flexible board 234 and a third flexible board 235. The second flexible board 234 is disposed inside the inclined section 211 and is electrically connected to the first rigid board 231. The third flexible board 235 is disposed inside the straight section 212 and is connected to the second rigid board 232. The microphone 24 includes at least two microphones. The sound receiving hole 213 includes a first sub-sound receiving hole 2131 and a second sub-sound receiving hole 2132. The first sub-sound receiving hole 2131 is disposed in the inclined section 211, and the second sub-sound receiving hole 2132 is disposed in the straight section 212. Among the at least two microphones 24, one microphone 24 is disposed in the inclined section 211 corresponding to the first sub-sound receiving hole 2131 and is electrically connected to the second flexible board 234. The other microphone 24 is disposed in the straight section 212 corresponding to the second sub-sound receiving hole 2132 and is electrically connected to the third flexible board 235. The microphone 24 is connected to the cavity wall of the mounting cavity 214. In this way, on the one hand, the second flexible circuit board 234 and the third flexible circuit board 235 can realize the electrical connection of the microphone 24; on the other hand, by setting the two microphones 24 in the inclined section 211 and the straight section 212 respectively, the sound pickup effect of the two microphones 24 can be improved and the mutual interference of the two microphones 24 can be avoided, which is conducive to improving the call effect or auxiliary hearing effect of the headset 100.

[0155] In some embodiments, to facilitate the assembly of the earphone 100, at least two of the first rigid board 231, the second rigid board 232, the first flexible board 233, the second flexible board 234, and the third flexible board 235 can be integrally disposed. As an example, the first rigid board 231 and the first flexible board 233 are integrally disposed.

[0156] Another example is that the first flexible board 233 and the second rigid board 232 are integrated into one unit.

[0157] Another example is that the first rigid board 231 and the second flexible board 234 are integrated into one unit.

[0158] Another example is that the second rigid board 232 and the third flexible board 235 are integrated into one unit.

[0159] In another exemplary configuration, the first rigid board 231, the first flexible board 233, and the second flexible board 234 are integrated into one unit.

[0160] In another exemplary configuration, the second rigid board 232, the first flexible board 233, and the third flexible board 235 are integrated into one unit.

[0161] In another exemplary configuration, the first rigid board 231, the second rigid board 232, and the first flexible board 233 are integrally arranged.

[0162] In another exemplary configuration, the first rigid board 231, the second rigid board 232, the first flexible board 233, and the second flexible board 234 are integrated into one unit.

[0163] In another exemplary configuration, the first rigid board 231, the second rigid board 232, the first flexible board 233, and the third flexible board 235 are integrated into one unit.

[0164] In another exemplary configuration, the first rigid board 231, the second rigid board 232, the first flexible board 233, the second flexible board 234, and the third flexible board 235 are integrated into one unit.

[0165] The integrated arrangement of the first rigid board 231, the second rigid board 232, the first flexible board 233, the second flexible board 234, and the third flexible board 235 facilitates the assembly of the earphone 100 and helps to reduce the assembly process of the earphone 100.

[0166] As an optional implementation method, such as Figure 12 As shown, the earphone 100 also includes a charging connector 4, which is disposed on the surface of the inclined section 211 near the earphone body 1 and is electrically connected to the circuit board 23. The charging connector 4 on the inclined section 211 enables charging of the earphone 100. Furthermore, compared to placing the charging connector 4 on the straight section 212, it avoids friction between the charging connector 4 and the inner wall of the charging case when the earphone 100 is stored inside, thus preventing damage to the charging connector 4 and extending the lifespan of the earphone 100.

[0167] It is understandable that when the earphone 100 is stored in the charging case, in order to prevent the earphone 100 from falling out, a magnetic component can be provided to make the earphone 100 adhere to the charging case. The magnetic component may include one or more, and this embodiment does not limit it.

[0168] Optionally, when there are multiple magnetic components, there can be 1, 2, 3, 4, etc., and this embodiment does not limit this.

[0169] Optionally, when there are multiple magnetic components, the multiple magnetic components can provide attraction in the same direction or attraction in different directions; this embodiment does not limit this. For example, such as... Figure 8 and Figure 12As shown, the first housing 11 is cylindrical, and the earphone 100 further includes a first magnetic member 51 and a second magnetic member 52. The first magnetic member 51 is disposed inside the first housing 11 and along the extending direction of the first housing 11, the first magnetic member 51 is disposed at the end of the first housing 11 away from the speaker component 12. The second magnetic member 52 is disposed on the side of the flat section 212 near the earphone body 1, and the second magnetic member 52 is located inside the flat section 212. Through the first magnetic member 51 and the second magnetic member 52, when the earphone 100 is stored in the charging case, it can provide better suction force for the earphone 100, which helps to prevent the earphone 100 from falling out of the charging case during activities. In particular, when the earphone 100 is plugged into a wearable device, the first magnetic member 51 and the second magnetic member 52 can provide suction force in different directions, which helps to firmly attach the earphone 100 to the earphone receiving slot of the wearable device.

[0170] As an alternative implementation, the first housing 11 and the inclined section 211 are integrally formed.

[0171] Optionally, the inclined section 211 and the straight section 212 are integrated.

[0172] Optionally, the first housing 11, the inclined section 211, and the straight section 212 are integrally formed.

[0173] The above-mentioned method of integrating the first housing 11, the inclined section 211, and the straight section 212 can save the assembly process between the first housing 11, the inclined section 211, and the straight section 212, which is conducive to the assembly of the earphone 100, thereby improving the assembly efficiency of the earphone 100 and thus improving the production efficiency of the earphone 100.

[0174] It is understandable that, in order to facilitate the installation of components such as the speaker component 12, battery 13, circuit board 23, and microphone 24, the inclined section 211 may include a bottom shell and a top shell that are connected and form an installation space inside, and the straight section 212 may also include a bottom shell and a top shell that are connected and form an installation space inside. The bottom shell of the inclined section 211 and the bottom shell of the straight section 212 are integrally formed with the first sub-shell 111, and the top shell of the inclined section 211 and the top shell of the straight section 212 are integrally formed with the second sub-shell 112.

[0175] Please see Figure 15 and Figure 16 , Figure 15 This is a schematic diagram of the structure of a wearable device (wireless earphones plugged into an earphone holder) provided in an embodiment of this application; Figure 16This is a schematic diagram of the structure of a wearable device (wireless earphones detached from an earphone holder) provided in an embodiment of this application. In a second aspect, this application also provides a wearable device 200, including a main body 201 and earphones 100 as described in the first aspect above. The main body 201 is provided with an earphone holder 202, which is configured to allow the earphones 100 to be pluggably connected to the main body 201. By providing installation space for the earphones 100 in the earphone holder 202 on the wearable device 200, a separate charging case for the earphones 100 is not required, making the earphones 100 easier to carry.

[0176] Optionally, the wearable device 200 mentioned above includes, but is not limited to, watches, bracelets, smart jewelry, and glasses. To facilitate the description of the specific structure of the wearable device 200, a watch will be used as an example below.

[0177] Please combine Figures 17 to 20 , Figure 17 This is a partial cross-sectional view of a wearable device (wireless earphones plugged into an earphone holder) provided in an embodiment of this application; Figure 18 yes Figure 17 A magnified view of a section at point C; Figure 19 This is a partial cross-sectional view of a wearable device (wireless earphones detached from the earphone holder) provided in an embodiment of this application; Figure 20 yes Figure 19 A partial enlarged view at point D. As an optional implementation, when the connecting arm 21 of the clamping portion 2 includes a second housing 21a, and the second housing 21a includes a straight section 212, the earphone body 1 is pluggably connected to the earphone receiving slot 202 along the extending direction X of the straight section. This approach facilitates the plugging and unplugging of the earphone 100, simplifying the plugging and unplugging process and improving the user experience. Furthermore, it reduces the installation space required for the earphone 100, saving space in the main body 201 of the wearable device 200, thus improving the space utilization of the wearable device 200 and facilitating its miniaturization.

[0178] Optionally, such as Figures 17 to 20As shown, the wearable device 200 also includes a wearable component 203, which is connected to the main body 201. When the second housing 21a also includes an inclined section 211, the earphone receiving slot 202 includes a first sub-receiving slot 2021 and a second sub-receiving slot 2022. The first sub-receiving slot 2021 and the second sub-receiving slot 2022 are connected, and the second sub-receiving slot 2022 is disposed between the main body 201 and the wearable component 203. The earphone body 1 and the inclined section 211 are pluggably connected to the first sub-receiving slot 2021, and the straight section 212 and the clamping arm 22 are pluggably connected to the second sub-receiving slot 2022. By utilizing the space between the wearable component 203 and the main body 201 to set the second sub-receiving slot 2022, the space of the main body 201 of the wearable device 200 can be further saved, thereby improving the space utilization rate of the wearable device 200 and facilitating the miniaturization design of the wearable device 200. Furthermore, when the wearable device 200 is a watch, the tilt section 211 is positioned to fit the transition shape between the wearable component 203 and the side surface of the main body 201 where the earphone receiving slot 202 is located, which helps to improve the aesthetics of the wearable device.

[0179] It is understood that when the wearable device 200 is a watch, the wearing component 203 is the watch strap. When the wearable device 200 is eyeglasses, the wearing component 203 is the temple, and so on. This embodiment does not limit this.

[0180] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
