[0042] To more clearly illustrate the technical solutions in the embodiments of this application or related technologies, the following will be described clearly and completely in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0043] When wearing open-back headphones, due to the different physical characteristics of different users, the size and curvature of their ears are also different, which will lead to poor adaptability of the ear hook. That is, since the shape of the ear does not match the ear hook, the ear hook is loose when worn, does not fit the ear tightly, and is easy to fall off.

[0044] For the above situation, please see Figure 1-Figure 2 The present application proposes an open-ear headphone 1, comprising a sound-emitting portion 10, an ear hook 20 and a battery compartment 30. The sound-emitting portion 10 is connected to one end of the ear hook 20, and the battery compartment 30 is connected to the other end of the ear hook 20. The ear hook 20 is used to be worn between the user's ear 2 and the head. At least a portion of the sound-emitting portion 10 is used to be worn in the concha cavity 40. The sound-emitting portion 10 has a sound outlet 111a, which is arranged toward the user's concha cavity 40 and ear canal. The sound in the open-ear headphone 1 enters the user's ear canal from the sound outlet 111a to provide the user with various sounds. The battery compartment 30 is used to provide power to the sound-emitting portion 10.

[0045] Regarding the sound-emitting portion 10 of the open earphone 1 in this embodiment, in some embodiments of the present application, such as Figure 14 As shown, the maximum width of the sound-emitting portion 10 along the first direction M is between 13.5 mm and 17.5 mm, where the first direction M is parallel to the extension direction of the battery compartment 30. For example, assuming the maximum width of the sound-emitting portion 10 along the first direction M is L5, preferably, the maximum width L5 of the sound-emitting portion 10 along the first direction M is 15.5 mm. It will be readily understood that at least a portion of the sound-emitting portion 10 is located in the cavum concha 40. This embodiment limits the maximum width of the sound-emitting portion 10 along the first direction M to ensure that the sound-emitting portion 10 is more stably positioned within the cavum concha 40, thereby reducing the risk of the open-ear earphone 1 falling off the user's ear 2.

[0046] In some embodiments, as Figure 3 As shown, the sound-emitting part 10 may include a sound-emitting part shell 11 and a movement 12 arranged in the sound-emitting part shell 11. The sound-emitting part shell 11 may include a main shell 111 and a cover 112. The cover 112 is a sheet structure, and the main shell 111 is a comma-like structure. The movement 12 is arranged inside the main shell 111, and the cover 112 can cover the main shell 111.

[0047] Specifically, such as Figure 3-Figure 4 As shown, the cover 112 and the main shell 111 are provided with a connecting assembly 13 near the edge. The connecting assembly 13 may include a first connecting member 131 provided on the cover 112 and a second connecting member 132 provided on the main shell 111. The cover 112 and the main shell 111 are connected by the cooperation of the first connecting member 131 and the second connecting member 132. The first connecting member 131 and the second connecting member 132 are located at the edges of the cover 112 and the main shell 111, so that the edge of the cover 112 and the main shell 111 are more firmly connected, which can prevent one end of the cover 112 from warping. The first connecting member 131 and the second connecting member 132 can be connected by means of snapping, plugging, bonding or screwing.

[0048] Exemplarily, one of the first connecting member 131 and the second connecting member 132 is a positioning hole, and the other of the first connecting member 131 and the second connecting member 132 is a reinforcement column. The reinforcement column is a raised structure, and the positioning hole is a recessed structure provided to cooperate with the reinforcement column. When the reinforcement column is inserted into the positioning hole, the cover body 112 and the main shell 111 are fitted together, ensuring that the position between the cover body 112 and the main shell 111 is accurate and stable. In addition, the reinforcement column and the positioning hole are located at the edges of the cover body 112 and the main shell 111, so that the edge of the cover body 112 is more firmly connected to the main shell 111, which can prevent one end of the cover body 112 from warping. Alternatively, one of the first connecting member 131 and the second connecting member 132 is a buckle, and the other of the first connecting member 131 and the second connecting member 132 is a slot. The buckle and the slot can be snap-fitted together, so that the cover body 112 and the main shell 111 are snap-fitted together.

[0049] like Figure 3-Figure 5As shown, a sound receiving hole 111b is respectively provided on the main shell 111 and the cover body 112. The movement 12 may further include at least two sound receiving parts (not shown in the figure), which may be microphones. Each sound receiving part can be arranged corresponding to a sound receiving hole 111b on the sound-emitting part shell 11, and the sound outlet hole 111a is arranged on the main shell 111, the sound receiving hole 111b on the main shell 111 is arranged adjacent to the sound outlet hole 111a, and the sound receiving hole 111b on the cover body 112 is arranged opposite to the sound outlet hole 111a, so that one of the two sound receiving parts is also arranged adjacent to the sound outlet hole 111a and corresponds to the sound receiving hole 111b on the main shell 111, and the other of the two sound receiving parts is arranged opposite to the sound outlet hole 111a and corresponds to the sound receiving hole 111b on the cover body 112, so that the sound inlet holes of the two sound receiving parts are arranged in opposite directions, so that the earphones can receive ambient sound more comprehensively, whether it is conversations in front or sounds from the side, they can be clearly captured, which can ensure that the open earphones 1 can more effectively capture sounds from different directions when worn.

[0050] Preferably, the sound hole 111a is a circular hole to ensure that the sound can be transmitted smoothly and evenly, and an ultrasonic mesh steel can be provided in the sound hole 111a. The ultrasonic mesh steel can effectively prevent foreign matter from entering the sound hole and avoid interfering with the sound quality, while allowing sound waves to pass smoothly and ensure the clarity and purity of the sound transmission.

[0051] Specifically, arranging the sound inlets of the two sound receiving parts in opposite directions can also help reduce sound interference and echoes. Specifically, when the sound inlets of the sound receiving parts face the same direction, sounds from certain directions may interfere due to reflection and superposition, affecting the sound reception quality. However, arranging the sound inlets in opposite directions can effectively reduce this interference, making the recording purer and clearer. In addition, when the open-back earphones 1 are worn on the head, the two sound receiving parts can be located on either side of the user's head. Arranging the sound inlets in opposite directions can better adapt to the head contour, reduce the sense of pressure, and improve wearing comfort.

[0052] like Figure 6-Figure 7As shown, the movement 12 on the sound-emitting part 10 bears the responsibility of sound output. The movement 12 is arranged inside the sound-emitting part housing 11 and corresponds to the sound outlet 111a. The movement 12 is integrated with a first speaker 121 and a second speaker 122. The first speaker 121 is used as an audio speaker and can correspond to the sound outlet 111a and transmit the audio signal to the user's ear 2 through the sound outlet 111a. The second speaker 122 is arranged on the side of the first speaker 121 away from the sound outlet 111a and is spaced apart from the first speaker 121, so that the first speaker 121 is 1 and the second speaker 122 form a dual-speaker structure in series, which can effectively reduce the interference between the two and ensure the clarity and quality of the audio output. The second speaker 122 is not only an ordinary audio output device, but also a noise reduction speaker. The second speaker 122 and the first speaker 121 jointly construct the rear sound cavity 124 of the first speaker 121. The second speaker 122 can detect ambient noise in real time and generate reverse sound waves to offset the ambient noise, which helps to further optimize the noise reduction performance of the open-ear headphones 1, thereby significantly improving the sound quality performance.

[0053] like Figure 6-Figure 7 As shown, the movement 12 may further include a bracket 123, which may be disposed between the first speaker 121 and the second speaker 122. Specifically, one end of the bracket 123 is disposed opposite the first speaker 121, ensuring precise alignment between the two. This not only makes the installation of the first speaker 121 more stable, but also ensures the efficiency and clarity of sound transmission. At the same time, the other end of the bracket 123 is used to support the second speaker 122, so that the first speaker 121, the bracket 123, and the second speaker 122 can be disposed sequentially along the same straight line, thereby enabling the first speaker 121, the bracket 123, and the second speaker 122 to form a series-connected dual-speaker structure. This series-connected dual-speaker structure not only reduces the sound interference between the first speaker 121 and the second speaker 122, but also enhances the stability of the overall structure.

[0054] Furthermore, the function of the bracket 123 is not limited to support and fixation. The bracket 123 also forms a rear acoustic cavity 124 for the first speaker 121 together with the first speaker 121 and the second speaker 122. The rear acoustic cavity 124 has a crucial impact on sound quality. It optimizes the sound propagation path, reduces sound reflection and interference, and thus improves sound quality. Through the close cooperation between the bracket 123 and the dual speakers, the rear acoustic cavity 124 is constructed more rationally and efficiently, bringing even better sound quality to the open-ear headphones 1.

[0055] like Figure 6-Figure 7As shown, in some embodiments, the bracket 23 is further provided with sound guide holes 123a connected to the rear sound cavity 124. These sound guide holes 123a can be arranged opposite to the acoustic holes 111d on the sound-emitting shell 11, so that the rear sound cavity 3 can be connected to the acoustic holes 111d. The coordinated use of the sound guide holes 123a and the acoustic holes 111d further enhances the sound propagation effect and makes the sound quality fuller and more three-dimensional.

[0056] Specifically, the acoustic hole 111d is usually a pressure relief hole or a tuning hole. When the acoustic hole 111d acts as a pressure relief hole, it can reduce the pressure in the ear canal, making the wearer feel more comfortable. Without this pressure relief hole, the bass may be improved, but the pressure in the ear canal will increase, which can easily cause hearing fatigue. In addition, if the pressure relief hole is closed, it may cause the diaphragm to deform slightly when vibrating, resulting in slightly abnormal sound distortion. When the acoustic hole 111d acts as a tuning hole, it can adjust the ultra-high frequency phase characteristics, improve high-frequency diffusion and eliminate high-frequency standing waves, making the sound diffusion more uniform. A tuning net and tuning cotton are usually attached to the inside of the tuning hole to more accurately adjust the sound. Without these structures, the sound may become turbid.

[0057] like Figure 3 As shown, the sound-emitting part 10 may further include an antenna component 141 and a touch component 142, and the antenna component 141 and the touch component 142 can be integrated into one, and the antenna component 141 and the touch component 142 are electrically connected to the movement 12 respectively, which can improve the overall function and convenience of the open earphone 1.

[0058] Specifically, the antenna component 141 primarily receives and transmits wireless signals, enabling the device to communicate wirelessly with the outside world, such as receiving Bluetooth signals, Wi-Fi signals, etc. Integrating the antenna component 141 within the sound-emitting portion 10 allows the open-earphone 1 to also have wireless communication capabilities, thereby providing a wider range of usage scenarios and a more convenient operating experience.

[0059] The touch component 142 provides a way for users to interact with the open earphones 1. Through touch operation, users can more intuitively control the various functions of the open earphones 1, such as adjusting the volume, switching songs, answering calls, etc. Integrating the touch component 142 in the sound-emitting part 10 can make the device more intelligent and user-friendly, thereby improving user satisfaction.

[0060] Integrating antenna component 141 and touch control component 142 into one unit not only reduces the size and weight of open-back earphones 1, but also lowers production and maintenance costs. Furthermore, the integrated design improves the overall performance and stability of open-back earphones 1, ensuring that all functions work together to provide a better user experience.

[0061] In addition, if Figure 4 As shown, a contoured groove 112a is provided on the side of the cover body 112 facing the main shell 111. The shape of the contoured groove 112a is the same as the shape of the integrated antenna component 141 and the touch component 142, so that the antenna component 141 and the touch component 142 can be placed in the contoured groove 112a, thereby reducing the volume occupied by the antenna component 141 and the touch component 142, and can further reduce the volume and weight of the open earphone 1.

[0062] Regarding the ear hook 20 of the open earphone 1 in this embodiment, in some embodiments of the present application, such as Figure 9 As shown, the ear hook 20 has a first supporting portion 23, and an arc-shaped wearing cavity is formed between the ear 2 and the head. When worn, the first supporting portion 23 is located in the upper part of the wearing cavity, and the first supporting portion 23 is located above the sound-emitting portion 10 along the vertical axis direction. Therefore, when the open-type earphones 1 are worn, the first supporting portion 23 squeezes the outer side of the ear 2 close to the head under the action of gravity. Therefore, the cross-section of the first supporting portion 23 is circular or arc-shaped. That is to say, the outer side surface of the first supporting portion 23 is set to an arc surface to increase the contact area between the first supporting portion 23 and the ear 2, thereby reducing the pressure of the first supporting portion 23 on the ear 2 and improving the wearing comfort of the open-type earphones 1.

[0063] In some embodiments of the present application, Figure 9 As shown, the cross section of the first support portion 23 can also be elliptical, with the long axis of the first support portion 23 parallel to the plane where the first side surface 151 of the sound-emitting portion 10 is located, and the short axis of the first support portion 23 perpendicular to the plane where the first side surface 151 is located. Figure 13-14 As shown in the figure, the minimum length of the major axis of the first support portion 23 is between 2.9 mm and 4.3 mm; the minimum length of the minor axis of the first support portion 23 is between 2.3 mm and 3.3 mm. For example, the minimum length of the major axis of the first support portion 23 is L6, and the minimum length of the minor axis of the first support portion 23 is L7. Preferably, the minimum length L6 of the major axis of the first support portion 23 is 3.6 mm, and the minimum length L7 of the minor axis of the first support portion 23 is 2.8 mm. This embodiment, by limiting the size of the first support portion 23, facilitates wearing the first support portion 23 in the upper portion of the wearing cavity.

[0064] In some embodiments, the ear hook 20 is generally made of silicone material, and the ear hook 20 is wrapped with memory metal or other materials to enhance the elasticity and stability of the ear hook 20, better adapt to different ear shapes, and when wearing the open earphone 1, the ear hook 20 can provide support to ensure that the ear hook 20 can fit firmly on the contour of the ear 2, and that the sound-producing part 10 can correspond to the ear canal, thereby reducing the pressure of the open earphone 1 on the ear 2. In the embodiment of the present application, the ear hook 20 includes a soft rubber shell and a metal wire 22 (such as Figure 11 As shown), the metal wire 22 is located in the soft rubber shell. It is easy to understand that the soft rubber shell is coated on the outer peripheral side of the metal wire 22. The soft rubber shell can make the ear hook 20 elastic and softer when worn, thereby improving the wearing comfort of the user; the metal wire 22 is preferably a memory titanium wire. The memory titanium wire has good elasticity, which is convenient for the user to adjust the wearing angle and clamping tightness of the ear hook 20, so that the open earphone 1 can be worn more firmly through the ear hook 20.

[0065] In some embodiments of the present application, Figure 11 As shown, on the earhook 20, the ratio of the length of the metal wire 22 within the soft rubber shell along the extension direction of the earhook 20 to the length of the soft rubber shell along the extension direction of the earhook 20 is greater than 0.55. This makes the length of the earhook 20 containing the metal wire 22 longer than the length not containing the metal wire 22. In other words, when the open-back earphone 1 is worn, a larger portion of the metal wire 22 on the earhook 20 can be deformed, thereby increasing the deformability of the earhook 20 and thus expanding the adjustable range of the earhook 20, improving the universality of the open-back earphone 1. For example, the length of the metal wire 22 along the extension direction of the earhook 20 is 31 mm, and the length of the soft rubber shell along the extension direction of the earhook 20 is 55 mm.

[0066] Specifically, the ratio of the length of the first support portion 23 to the length of the soft rubber shell is greater than 0.4, thereby ensuring the distribution area of ​​the first support portion 23 on the ear hook 20, so that when the open earphones 1 are worn, the first support portion 23 contacts the upper wall surface of the wearing cavity as much as possible. In other words, the part that contacts the user's ear is the circular or arc-shaped surface of the first support portion 23 as much as possible, thereby improving the wearing comfort of the open earphones 1.

[0067] In some embodiments of the present application, the soft rubber shell can be made of silicone, the hardness of the soft rubber shell is between 40A and 45A, and the diameter of the metal wire 22 is between 0.5mm and 0.7mm.

[0068] It should be noted that Figure 8 (a), (b), and (c) are the “wearing consistency test verification curves” of different users wearing open-ear headphones 1. Figure 8(e) in the figure is the “stability verification curve diagram” of the same user wearing the open earphone 1.

[0069] In the "Wearing Consistency Test Verification Curve", the horizontal axis represents the sound pressure level (SPL) of the sound, and the vertical axis represents the sound pressure level (SPL) of the sound, the unit is dB. Figure 8 The different curve numbers "TXM", "WK", and "JYH" given in (a), (b), and (c) represent the codes of three different users, respectively. "T1" represents the open-ear headphone 1 in this embodiment. The five curves represent five measurements of wearing the open-ear headphone 1. The same open-ear headphone 1 has a wearing consistency deviation of less than 6dB in multiple wearing tests of different users, indicating that the ear hook 20 of the open-ear headphone 1 in this embodiment has better elasticity and higher wearing consistency.

[0070] The horizontal axis in the "Stability Verification Curve" represents the frequency of the sound in Hertz (Hz), and the vertical axis represents the sound pressure level (SPL) in dB. Figure 8 The curve given in (e) shows that the same user wore the open-ear headphones 1 for 5 measurement tests. When the same user wore the open-ear headphones 1 in this embodiment multiple times, the fluctuation range of wearing stability was within 1dB to 3dB, indicating that the open-ear headphones 1 in this embodiment have higher wearing stability.

[0071] Depend on Figure 8 It can be seen from the "Wearing Consistency Test Verification Curve Chart" and the "Stability Verification Curve Chart" that the ear hook 20 of the open earphone 1 in this embodiment has better elasticity, which makes the ear hook 20 in this embodiment softer and more comfortable, and has higher wearing consistency and stability.

[0072] For the ear hook 20 and the sound emitting part 10 of the open earphone 1 in this embodiment, Figure 9 As shown, the sound-emitting part 10 is connected to one end of the ear hook 20, and one end of the main shell 111 can be provided with a card interface 111c running through its own interior. When the clamping part 21 located at one end of the ear hook 20 is inserted into the card interface 111c, a part of the clamping part 21 can extend into the main shell 111, and the part of the clamping part 21 located in the main shell 111 can be provided with a clamping block 21, and the clamping block 21 can be clamped with the inner wall of the main shell 111 forming the card interface 111c, so that the clamping part 21 can be buckled together with the main shell 111, so that one end of the ear hook 20 is connected to the main shell 111, that is, the sound-emitting part 10 is connected to one end of the ear hook 20, so that when the ear hook 20 is worn on the ear 2, the sound-emitting part 10 can be supported in the ear canal of the ear 2.

[0073] For example, Figure 10As shown, a plurality of glue dispensing grooves 212 can be further provided on the circumferential side wall of the clamping portion 21, and at least one glue dispensing groove 212 is arranged next to the clamping block 211. Each glue dispensing groove 212 is provided with glue, and the glue can further bond the clamping portion 21 and the main shell 111 together, so that one end of the ear hook 20 and the sound-emitting portion 10 can be connected more firmly. In addition, the glue dispensing groove 212 is provided next to the clamping block 211, which can make the inverted buckle structure of the clamping block 211 and the main shell 111 more stable and less likely to loosen.

[0074] In some embodiments of the present application, Figure 14 As shown, the maximum distance between the sound-emitting part 10 and the ear hook 20 is between 13.2 mm and 17.2 mm. For example, the maximum distance between the sound-emitting part 10 and the ear hook 20 is L3. Preferably, the maximum distance L3 between the sound-emitting part 10 and the ear hook 20 is 15.2 mm.

[0075] Specifically, part of the sound-emitting part 10 is located in the concha cavity 40 and abuts against the inner wall surface of the ear 2, and the ear hook 20 is located in the upper part of the wearing cavity and abuts against the outer wall surface of the ear 2. This embodiment limits the distance between the sound-emitting part 10 and the ear hook 20 so that the sound-emitting part 10 and the ear hook 20 can better clamp the top of the user's ear 2 and improve the wearing stability of the open earphone 1.

[0076] Further, such as Figure 9 As shown, the sound-emitting portion 10 includes a free end 161 for abutting against the inner wall surface of the ear 2, so the outer side surface of the free end 161 can be set as an arc surface to increase the contact area between the free end 161 and the ear 2, thereby reducing the pressure of the free end 161 on the ear 2 and improving the wearing comfort of the open earphone 1.

[0077] For the battery compartment 30 of the open-earphone 1 in this embodiment, Figure 11 As shown, the open earphones 1 also include a charging cable 40, and the battery compartment 30 may include a compartment shell and a battery pack (not shown in the figure). The compartment shell is shaped like a capsule, and the battery pack is arranged in the compartment shell. The compartment shell can be snapped onto the end of the ear hook 20 away from the main shell 111, and one end of the charging cable 40 can be electrically connected to the battery pack. The charging cable 40 is passed through the hollow cavity inside the ear hook 20, and the other end of the charging cable 40 extends into the main shell 111 and is electrically connected to the movement 12, so that the battery pack can power the movement 12, and the battery pack can be charged through the charging module on the movement 12.

[0078] In some embodiments, the battery pack can be connected to either a male or female socket, while the charging cable 40 is provided with the other of the male and female sockets. Specifically, the male and female sockets are complementary, having different shapes and structures so that they can be tightly plugged together. When the battery pack is equipped with a male or female socket, the charging cable 40 will be equipped with a corresponding female or male socket to ensure that the two can be properly connected. During the plugging process, simply align the socket on the charging cable 40 with the socket on the battery pack and gently insert it. Once plugged in, a stable electrical connection will be formed between the battery pack and the charging cable 40, allowing current to flow from the charging cable 40 to the battery pack. The provision of male and female sockets can facilitate assembly.

[0079] In some embodiments of the present application, Figure 11 、 Figure 14 As shown, the battery compartment 30 is a cylindrical structure, and the diameter of the battery compartment 30 is between 8 mm and 12 mm. For example, the diameter of the battery compartment 30 is L4, preferably, the diameter L4 of the battery compartment 30 is 10 mm. This embodiment, by limiting the diameter of the battery compartment 30, facilitates wearing the battery compartment 30 in the lower part of the wearing cavity.

[0080] For the open earphone 1 in this embodiment, Figure 1-Figure 2 As shown, the sound-emitting portion 10 is connected to one end of the ear hook 20, and the battery compartment 30 is connected to the other end of the ear hook 20. The wearing state of the open-back earphone 1 refers to the orientation of the earphone when it is worn on the user's ear 2. A semi-arc-shaped wearing cavity is formed between the user's ear 2 and the head. When the open-back earphone 1 is worn, the ear hook 20 is located in the upper portion of the wearing cavity, and the battery compartment 30 is located in the lower portion of the wearing cavity. Along the sagittal axis, the sound-emitting portion 10 extends forward of the user's head out of the wearing cavity and is at least partially located in the cavum concha 40.

[0081] In some embodiments of the present application, the ratio of the length of the soft rubber shell along the extension direction of the ear hook 20 to the overall length of the open earphone 1 from the sound-emitting part 10 through the ear hook 20 to the battery compartment 30 is greater than 0.47, so that nearly half of the length of the open earphone 1 is composed of the soft rubber shell. That is, when the open earphone 1 is worn, the part of the ear hook 20 that contacts the human skin uses the soft rubber shell as much as possible, which not only increases the contact area between the soft rubber shell and the human skin, but also makes the open earphone 1 more comfortable to wear.

[0082] The extension direction of the earhook 20 refers to the direction in which the earhook 20 extends from the first end connected to the sound-emitting portion 10 to the second end connected to the battery compartment 30. In other words, the extension direction of the earhook 20 is arc-shaped. The overall length of the open-back earphone 1 refers to the length of the open-back earphone 1 from the end of the sound-emitting portion 10 away from the earhook 20 along the extension direction of the earhook 20 to the end of the battery compartment 30 away from the earhook 20. For example, the length of the soft rubber shell along the extension direction of the earhook 20 is 55 mm, and the overall length of the open-back earphone 1 is 116 mm.

[0083] In some embodiments of the present application, Figure 12 As shown, the sound-emitting portion 10 has a first side surface 151, which is disposed away from the cavum concha 40 and opposite the sound outlet 111a. When the open-back earphone 1 is worn, the ear hook 20 is partially located in the wearing cavity between the user's ear 2 and head, and the sound-emitting portion 10 is located in the cavum concha 40. Therefore, the ear hook 20 is closer to the user's head than the sound-emitting portion 10. At this time, the angle between the central axis of the battery compartment 30 and the plane containing the first side surface 151 is between 4.5° and 6.5°. For example, assuming that the angle between the central axis of the battery compartment 30 and the plane containing the first side surface 151 is α, preferably, the angle α between the central axis of the battery compartment 30 and the plane containing the first side surface 151 is 5.5°.

[0084] In some embodiments of the present application, Figure 13 As shown, the angle between the central axis of the ear hook 20 and the plane on which the first side surface 151 lies is between 5° and 7°. For example, assuming that the angle between the central axis of the ear hook 20 and the plane on which the first side surface 151 lies is β, preferably, the angle β between the central axis of the ear hook 20 and the plane on which the first side surface 151 lies is 6°.

[0085] It can be understood that the wearing of the open earphones 1 is achieved by the ear hook 20 and the sound-emitting part 10 working together to clamp the user's ear 2. This embodiment limits the angle between the central axis of the battery compartment 30 and the plane where the first side surface 151 is located, and the angle between the central axis of the ear hook 20 and the plane where the first side surface 151 is located, so that the space formed between the battery compartment 30 and the sound-emitting part 10, and the ear hook 20 and the sound-emitting part 10 can clamp the user's ear 2 more stably, thereby reducing the risk of the open earphones 1 falling off the user's ear 2.

[0086] In some embodiments of the present application, the sound-emitting portion 10 has a second side surface 152 (eg, Figure 5 As shown), the sound hole 111a is provided on the second side surface 152, and the angle between the plane where the first side surface 151 is located and the plane where the second side surface 152 is located is 0-5°.

[0087] In some embodiments of the present application, the battery compartment 30 includes a first end portion 31 (eg, Figure 5 As shown, the distance between the first end portion 31 and the sound-emitting portion 10 in the longitudinal direction of the battery compartment 30 is between 11 mm and 15 mm. For example, the height difference between the first end portion 31 and the sound-emitting portion 10 along the extending direction of the battery compartment 30 is denoted as L1. Preferably, the height difference L1 between the first end portion 31 and the sound-emitting portion 10 along the extending direction of the battery compartment 30 is 13 mm.

[0088] It should be noted that when wearing the open-back earphones 1, this embodiment limits the distance between the first end portion 31 and the sound-emitting portion 10 along the extension direction of the battery compartment 30. This allows the extended length of the battery compartment 30 to occupy more space in the lower portion of the wearing cavity. This increases the contact area between the ear hook 20 and the battery compartment 30 and the user's ear 2, allowing the open-back earphones 1 to more stably clamp the user's ear 2, thereby reducing the risk of the open-back earphones 1 falling off the user's ear 2. Furthermore, the provision of the battery compartment 30 also allows the user to pick up the open-back earphones 1. By grasping the sound-emitting portion 10 and the battery compartment 30, the user can remove the open-back earphones 1 from the ear 2 in a direction opposite to the extension direction of the battery compartment 30.

[0089] In some embodiments of the present application, Figure 9 As shown, the sound-emitting part 10 has a free end 161 and a connecting end 162, the connecting end 162 is connected to one end of the ear hook 20, the free end 161 faces the battery compartment 30, and is spaced apart from the battery compartment 30, wherein the free end 161 is used to abut against the inner wall surface of the ear 2 when the open-type earphones 1 are worn, and the space between the free end 161 and the battery compartment 30 forms a clamping space for clamping the user's ear 2, so as to facilitate the wearing of the open-type earphones 1.

[0090] In some embodiments of the present application, Figure 14 As shown, the minimum distance between the free end 161 and the battery compartment 30 is between 1.2 mm and 1.8 mm. For example, the minimum distance between the free end 161 and the battery compartment 30 is L2. Preferably, the minimum distance L2 between the free end 161 and the battery compartment 30 is 1.5 mm.

[0091] Specifically, the free end 161 abuts the inner wall of the user's ear 2, and the battery compartment 30 abuts the outer wall of the user's ear 2. This embodiment limits the distance between the free end 161 and the battery compartment 30 so that the free end 161 and the battery compartment 30 can better clamp the side of the user's ear 2 and improve the wearing stability of the open-ear earphone 1. The inner wall of the ear 2 refers to the inner side wall of the ear 2 that forms the cavum concha 40, and the outer wall of the ear 2 refers to the outer side of the ear 2 facing the head.

[0092] In some embodiments of the present application, when the open earphones 1 are worn, the center of gravity of the battery compartment 30 and the center of gravity of the sound-emitting part 10 are located on the same vertical axis, thereby reducing the possibility of the open earphones 1 shaking due to unbalanced force when worn.

[0093] In some embodiments of the present application, the center of gravity of the open earphone 1 is located on the side of the sound-emitting part 10 close to the battery compartment 30 , or the center of gravity of the open earphone 1 is located on the side of the battery compartment 30 close to the sound-emitting part 10 .

[0094] Specifically, the sound-emitting portion 10 and the battery compartment 30 are located on opposite sides of the ear hook 20. When the open-back earphones 1 are worn, the ear hook 20 and the battery compartment 30 are located in the wearing cavity between the ear 2 and the head. The contact surface between the ear 2 and the ear hook 20 will bear most of the gravity of the open-back earphones 1. The embodiment of the present application can enable the sound-emitting portion 10 and the top of the ear hook 20 to clamp the ear 2, and form a force on the ear 2 that clamps the base of the ear 2 backward. Taking the example of the open-back earphones 1 where the center of gravity is located on the side of the sound-emitting portion 10 close to the battery compartment 30, the ratio of the distance from the center of gravity to the end of the sound-emitting portion 10 away from the battery compartment 30 to the distance from the center of gravity to the end of the battery compartment 30 away from the sound-emitting portion 10 is between 0.8 and 1.2.

[0095] In some embodiments of the present application, the ratio between the mass of the battery compartment 30 and the mass of the sound-emitting part 10 is between 0.9 and 1.1. Preferably, the ratio between the mass of the battery compartment 30 and the mass of the sound-emitting part 10 is 1, and the mass of the battery compartment 30 is the same as the mass of the sound-emitting part 10. As a result, when the open-type earphones 1 are worn, the center of balance of the open-type earphones 1 can be positioned at the top of the ear hook 20, that is, the center of balance of the open-type earphones 1 is located at the position where the top of the ear hook 20 contacts the user's ear, thereby reducing the forward or backward deviation of the open-type earphones 11.
