Technical Field

[0004] The present application relates to the technical field of earphones, and in particular to an earphone and an ear clip with multiple usage postures. Background Art

[0005] Headphones are widely used in people's daily lives and can be used with electronic devices such as mobile phones and computers. Among them, ear-hook headphones have a structure configured as an ear clip, which is called an ear clip-type headphone. The ear clip-type headphone includes a speaker chamber near the wearer's ear canal and a balance module placed on the back of the ear. The speaker chamber and the balance module are connected by an ear clip, and the ear clip provides a clamping force so that the speaker chamber and the balance module can be clamped and attached to the wearer's ear. Existing ear clip-type headphones are mostly open-type headphones, which use the clamping force of the ear clip to keep the headphones worn on the ears. The wearing method of this type of headphones is single, resulting in a single function and shape of the headphones. It is impossible to change the wearing posture according to the user's needs, and it is also impossible to achieve more headphone shape switching.

DETAILED DESCRIPTION

[0058] The present application provides an earphone. The following first explains the wearing state involved in the text, and the definitions of the front side, back side, upper side, and lower side of the ear.

[0059] Example 1

[0060] Please refer to Figure 1, which is a schematic diagram of the structure of the ear. Among them, the characters in Figure 1 show some physiological positions of the ear. The user's ear may include the helix, scaphoid, antihelix, triangular fossa, concha, ear foramen, tragus, and earlobe, wherein the concha may include the scaphoid and the cavum concha, and the ear foramen may also be called the external auditory meatus or the opening of the external auditory canal. The front and back sides of the ear are defined as follows: the "front side of the ear" mentioned in this application is a concept relative to the "back side of the ear", the former refers to the side of the ear away from the head, and the latter refers to the side of the ear facing the head, the "upper edge of the ear" refers to the outer edge of the ear's helix facing upward, and the "lower edge of the ear" refers to the outer edge of the ear's helix facing downward, and they are all for the user's ear.

[0061] The definition of wearing state is as follows: The "wearing state" described in this application is a stable wearing state after the earphone is stably worn on the ear of the human body (as shown in Figures 2 to 4, Figure 2 is a first state diagram of the earphone provided in an embodiment of the present application when worn on the ear, Figure 3 is a structural schematic diagram of the structure shown in Figure 2 from another perspective, and Figure 4 is a second state diagram of the earphone provided in an embodiment of the present application when worn on the ear). For example, as shown in Figure 2, the state of the earphone in Figure 2 can be understood as the first wearing state. At this time, the sound-emitting part 12 of the earphone 10 does not cover the ear hole area, or the sound-emitting part 12 of the earphone 10 is not inserted into the ear hole. It can also be understood that in the first wearing state, the earphone 10 is worn in an open manner. As shown in FIG4 , the state of the earphone 10 in FIG4 can be understood as the second wearing state. In this state, the position of the sound-emitting portion 12 of the earphone 10 is closer to the ear canal than in the first wearing state. In this state, the sound-emitting portion 12 can at least partially cover the ear canal area, or in other words, the sound-emitting portion 12 of the earphone 10 can be partially inserted into the ear canal. This can also be understood as the second wearing state, in which the earphone 10 is worn in the ear. Of course, due to individual differences among users, the actual wearing state of the earphone 10 may differ from the aforementioned wearing state.

[0062] It should be noted that in ear-clip headphones, the ear-clip headphones include a speaker chamber close to the wearer's ear canal and a balance module placed on the back of the ear, wherein the speaker chamber and the balance module are connected by an ear clip, and the ear clip provides a clamping force so that the speaker chamber and the balance module can be clamped and attached to the wearer's ear.

[0063] Since the ear clip in the existing ear-clip earphones only provides the connecting force between the speaker chamber and the balance module and the clamping force for clamping the ear, the ear clip itself cannot or is difficult to accurately adjust the posture, so that the earphones after wearing are in a single posture relative to the wearer. For example, the existing ear-clip earphones can only provide an open wearing method and can be used as open earphones, that is, the speaker chamber can only be located outside the ear hole, and cannot be used as in-ear earphones. The earphones cannot change the wearing posture according to user needs to achieve different wearing modes, and the experience is poor.

[0064] Based on this, an embodiment of the present application provides an earphone to solve the problem of a single wearing posture of the earphone.

[0065] Please refer to Figures 5 and 6 in conjunction with Figures 2 to 4. Figure 5 is a schematic diagram of a first configuration of the earphones provided in an embodiment of the present application, and Figure 6 is a schematic diagram of the configuration of the earphones shown in Figure 5 in another configuration. It will be appreciated that the adjustment member 14 shown in Figures 5 and 6 is typically embedded within the ear clip portion 13 and is not visible. For ease of description, it is illustrated as being visible, for example, by removing a portion of the material covering the adjustment member 14.

[0066] The earphone 10 may include a balancing portion 11, a sound-emitting portion 12, an ear clip portion 13, and an adjustment member 14. The sound-emitting portion 12 is provided with a speaker (not shown). It is understood that, to facilitate sound production, the sound-emitting portion 12 may be provided with at least one sound outlet (not shown), which is acoustically coupled to the speaker. Thus, when the sound-emitting portion 12 is located in front of the ear, sound may be transmitted to the ear canal through the sound outlet, allowing the user to hear the corresponding sound information.

[0067] One end of the ear clip portion 13 is connected to the sound-producing portion 12, and the other end of the ear clip portion 13 bends and extends toward the balance portion 11 and is connected thereto. The ear clip portion 13 can provide a certain clamping force. As will be appreciated, when the earphone 10 is worn on the ear, the balance portion 11 is located at the back of the ear, and the sound-producing portion 12 is located at the front of the ear. The ear clip portion 13 bends and extends from the back of the ear through the helix to the front of the ear. Thus, under the clamping force of the ear clip portion 13, the balance portion 11 and the sound-producing portion 12 can clamp the ear.

[0068] The adjustment member 14 is disposed within the ear clip portion 13 and is used to adjust the bending state of the ear clip portion 13 to enable the earphone 10 to switch between a first wearing state and a second wearing state. As shown in Figures 2 and 3 , in the first wearing state, the balancing portion 11 is located behind the ear, and the sound-emitting portion 12 is located in front of the ear and outside the ear canal. The balancing portion 11 and the sound-emitting portion 12 clamp the ear under the action of the adjustment member 14 and the ear clip portion 13.

[0069] As shown in Figure 4, in the second wearing state, the sound-emitting portion 12 is positioned closer to the ear canal than in the first wearing state, and the sound-emitting portion 12 can at least partially cover the ear canal. Due to differences in ear structure between users, the adjustment of the ear clip portion 13 by the adjustment member 14 in the second wearing state may vary. However, after adjustment is completed, in the second wearing state, the sound-emitting portion 12 can at least partially cover the ear canal.

[0070] As will be appreciated, the earphone 10 provided herein utilizes an adjustment member 14 disposed on the ear clip portion 13 of the earphone 10 to adjust the curvature of the ear clip portion 13. This allows the relative distance between the balancing portion 11 and the sound-emitting portion 12 to be changed, thereby enabling the earphone 10 to switch between a first wearing position and a second wearing position. In the first wearing position, the balancing portion 11 is located behind the ear, the sound-emitting portion 12 is located in front of the ear, and the sound-emitting portion 12 is located outside the ear canal. The balancing portion 11 and the sound-emitting portion 12 sandwich the ear, allowing the earphone 10 to function as an open-ear earphone 10. In the second wearing position, the sound-emitting portion 12 is positioned closer to the ear canal than in the first wearing position, such that the sound-emitting portion 12 at least partially covers the ear canal. In this case, the earphone 10 can function as an in-ear earphone 10. Thus, the adjustment member 14 allows the earphone 10 to have at least two different wearing positions, effectively changing the wearing position of the earphone 10 according to the user's needs and enhancing the user experience.

[0071] It is also understood that the headset 10 may further include a motherboard and a battery. The motherboard is primarily used to control the sound of the speaker or implement other control functions or information processing functions, while the battery is primarily used to provide power to the motherboard or speaker of the headset 10, or other electronic components in the headset 10 that require power. Of course, the headset 10 described in this application may also include microphones such as microphones and pickups, and may further include communication devices such as Bluetooth and NFC (Near Field Communication), which are electrically connected to the motherboard and battery via corresponding conductors to implement the corresponding functions.

[0072] As an example, the speaker can be installed in the sound-emitting part 12, and when the earphone 10 is in the wearing state, the sound-emitting part 12 can be tightly attached to the user's ear under the action of the pressing force. Furthermore, when the earphone 10 is in the wearing state, since the sound-emitting part 12 is mainly located in front of the user's ear, in order to make the earphone 10 better clamped to the ear, the balance part 11 is a component that balances the weight of the earphone 10. The balance part 11 is located on the back side of the ear. In this way, the balance part 11 and the sound-emitting part 12 can work together to achieve the effect of balancing weight. In order to make rational use of space, based on this, one of the mainboard, battery and Bluetooth module can be arranged in the sound-emitting part 12, and the other two can be arranged in the balance part 11, or two of them can be arranged in the sound-emitting part 12, and the other one can be arranged in the balance part 11, or all three can be arranged in the sound-emitting part 12, or all three can be arranged in the balance part 11. For example, the mainboard can be arranged in the sound-emitting part 12, and the battery and Bluetooth module can be arranged in the balance part 11.

[0073] Of course, those skilled in the art will readily appreciate that the aforementioned distribution of electronic components between the sound-producing portion 12 and the balancing portion 11 is merely exemplary. Those skilled in the art may modify the structural components of the sound-producing portion 12 and the balancing portion 11 as needed. Adjustments to these components in various locations are included in the technical solution of this application and have no impact on the weight distribution, so these adjustments will not be discussed further herein. In this manner, the weight of the earphone 10 can be more evenly distributed between the two ends, ensuring that the earphone 10 does not slip when worn, at least when not in motion.

[0074] Of course, it is also understandable that when a user wears the earphones 10, the user's ears bear most of the weight of the earphones 10, which may easily cause discomfort when worn for long periods of time. To this end, the balance portion 11, the sound-producing portion 12, the ear clip portion 13, and other structures can be made of softer materials (such as polycarbonate, polyamide, acrylonitrile-butadiene-styrene copolymer, silicone, leather, fabric, etc.) to improve the wearing comfort of the earphones 10.

[0075] It can also be understood that, since the balancing part 11 and the sound-emitting part 12 need to be installed with various electronic components, the balancing part 11 and the sound-emitting part 12 can be made of a harder material, such as a hard plastic part. Of course, in order to take into account the wearing comfort, the balancing part 11 and the sound-emitting part 12 can be provided with an elastic coating layer such as a softer material (such as polycarbonate, polyamide, acrylonitrile-butadiene-styrene copolymer, silicone, leather, fabric, etc.) in at least the area in contact with the user's skin, or sprayed with elastic paint, etc.

[0076] Furthermore, to improve the structural strength of the earphone 10, a support structure (not shown) may be provided within the ear clip portion 13, such as an elastic metal wire made of spring steel, titanium alloy, titanium-nickel alloy, chromium-molybdenum steel, aluminum alloy, copper alloy, or the like. It will be appreciated that the length of the support structure may be at least one-fifth the length of the ear clip portion 13. In other words, the support structure may be provided within a small section of the ear clip portion 13, or may be provided throughout the entire ear clip portion 13.

[0077] It should be noted that in the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more features.

[0078] As can be understood, to facilitate wearing the earphone 10, please continue to refer to Figures 5 and 6. The ear clip portion 13 is arc-shaped and includes a first connecting segment 131 and a second connecting segment 132 that are connected to each other. The first connecting segment 131 is connected to the sound-emitting portion 12, and the second connecting segment 132 is connected to the balancing portion 11. In other words, one end of the first connecting segment 131 is connected to the sound-emitting portion 12, the other end of the first connecting segment 131 is connected to the second connecting segment 132, and the end of the second connecting segment 132, which is away from the first connecting segment 131, is connected to the balancing portion 11.

[0079] Among them, the connection between the first connecting section 131 and the sound-emitting part 12 can be a fixed connection or a rotational connection. It can be understood that when the first connecting section 131 is rotationally connected to the sound-emitting part 12, the sound-emitting part 12 can be adjusted to a certain angle relative to the first connecting section 131 so that the sound-emitting part 12 can better fit the ear.

[0080] Similarly, it can be understood that the connection between the second connecting segment 132 and the balancing part 11 can be a fixed connection or a rotational connection. It can be understood that when the second connecting segment 132 is rotationally connected to the balancing part 11, the balancing part 11 can be adjusted to a certain angle relative to the second connecting segment 132 so that the balancing part 11 can better fit the ear.

[0081] In the embodiment of the present application, in the first wearing state, the balancing portion 11 is located at the back of the ear, the sound-emitting portion 12 is located at the front of the ear and outside the ear canal, and the balancing portion 11 and the sound-emitting portion 12 clamp the ear. In the second wearing state, the position of the sound-emitting portion 12 is closer to the ear canal relative to the position of the sound-emitting portion 12 in the first wearing state, and the sound-emitting portion 12 covers at least part of the ear canal area. It can be understood that the bending state of the ear clip portion 13 is different in the first wearing state and the second wearing state, that is, the bending state of the ear clip portion 13 needs to be changed so that the earphone 10 can switch between the first wearing state and the second wearing state. In particular, in order to facilitate changing the positional relationship between the sound-emitting portion 12 and the balancing portion 11, the adjustment member 14 can be provided at least on the first connecting section 131 for adjusting the bending state of the first connecting section 131 so that the earphone 10 can switch between the first wearing state and the second wearing state.

[0082] When the first connecting section 131 is adjusted by the adjusting member 14, it can exhibit different bending states. When the bending state of the first connecting section 131 is different, the relative position between the sound-emitting portion 12 and the balancing portion 11 will also change, thereby enabling the earphone 10 to switch between a first wearing state and a second wearing state. For example, in the first wearing state, the sound-emitting portion 12 is located in front of the ear and outside the ear canal. When the bending state of the first connecting section 131 is adjusted by the adjusting member 14, the earphone 10 can switch from the first wearing state to the second wearing state, and the position of the sound-emitting portion 12 can be made closer to the ear canal relative to the position of the sound-emitting portion 12 in the first wearing state, and the sound-emitting portion 12 at least covers a portion of the ear canal area.

[0083] Specifically, please refer to Figures 2 and 4 in combination with Figure 1. In the first wearing state and the second wearing state, the earphone 10 is roughly located in the middle of the ear, or in other words, the earphone 10 can be roughly located above the middle of the ear or below the middle of the ear.

[0084] It can be understood that, as shown in Figure 1, the ear includes two parts: the upper edge of the ear and the lower edge of the ear. The middle part of the ear can be understood as the part roughly located in the middle of the ear between the upper edge of the ear and the lower edge of the ear, such as the part where the concha cavity is located.

[0085] It is also understandable that, since the sound-emitting portion 12 needs to be moved to at least partially cover the ear canal area in the second wearing state, if the length of the first connecting section 131 after the bending state is changed is not enough for the sound-emitting portion 12 to extend into the ear canal area, the position of the balancing portion 11 needs to be slightly adjusted. For example, the balancing portion 11 can be adjusted toward the front of the ear so that the sound-emitting portion 12 can be moved to at least partially cover the ear canal area. At this time, the balancing portion 11 can at least partially contact the helix. Of course, due to individual ear differences, if the length of the first connecting section 131 after the bending state is changed is sufficient for the sound-emitting portion 12 to extend into the ear canal area, there is no need to adjust the balancing portion 11 toward the front of the ear. In this case, the balancing portion 11 is still located at the back of the ear.

[0086] It is also understood that in the first wearing state, the earphone 10 can be clamped by the balancing portion 11 and the sound-producing portion 12 under the action of a clamping force. The clamping force may be provided by only the ear clip portion 13 or by both the ear clip portion 13 and the adjustment member 14, and this is not a limitation in the present application.

[0087] In the second wearing state, the earphone 10 can be clamped so that the balancing part 11 is attached to the ear, and since the sound-emitting part 12 can be at least partially inserted into the ear canal, the ear canal can generate a certain supporting force on the sound-emitting part 12. At this time, the earphone 10 can be stably worn on the ear under the combined action of the clamping force and the supporting force.

[0088] In order to make the earphone 10 more stably worn on the ear, please refer to Figures 1, 2 and 5. The sound-emitting part 12 includes a first abutting surface 121 facing the side where the concha cavity is located. In the first wearing state, the first abutting surface 121 at least partially abuts against the concha cavity.

[0089] Among them, the sound-emitting part 12 can also include an insertion section 122 and a fixed section 123 that are connected to each other. The fixed section 123 is connected to the ear clip part 13, such as the fixed section 123 is connected to the first connecting section 131 of the ear clip part 13. A sound outlet is provided at one end of the insertion section 122 close to the ear hole. In the second wearing state, the insertion section 122 is at least partially inserted into the ear hole.

[0090] The sound outlet can be set on the side of the insertion section 122 facing the ear hole, so that the sound can be better transmitted into the ear hole, improving the quality of sound transmission.

[0091] In some embodiments, to further enhance the wearing stability of the earphone 10, in the first wearing position, the sound-emitting portion 12 and the balancing portion 11 are clamped against the ear, with their orthographic projections on the ear at least partially overlapping. This allows the sound-emitting portion 12 and the balancing portion 11 to be roughly opposite each other on the front and back sides of the ear, thereby achieving a better clamping effect.

[0092] It is understandable that in both the first and second wearing states, the second connecting segment 132 can more or less provide a clamping force. Therefore, the absolute value of the first average radius of curvature of the first connecting segment 131 is greater than the absolute value of the second average radius of curvature of the second connecting segment 132. As such, the curvature of the second connecting segment 132 is greater than that of the first connecting segment 131. Therefore, the second connecting segment 132 can provide sufficient clamping force in both wearing states, allowing the earphone 10 to be worn more stably.

[0093] It can also be understood that, as shown in Figures 2 and 4, in the first wearing state, the first connecting section 131 is bent facing the ear to form an arc-shaped first curved shape 131a. In the process of switching the earphone 10 from the first wearing state to the second wearing state, the bending degree of the first connecting section 131 can be gradually adjusted to be more gentle or reversed, so that the sound-emitting part 12 can be moved to cover at least part of the ear hole area. For example, when adjusted to the second wearing state, the first connecting section 131 is adjusted to bend back to the ear to form an arc-shaped second curved shape 131b, that is, the direction of the opening formed by the first curved shape 131a is opposite to the direction of the opening formed by the second curved shape 131b.

[0094] Of course, it is understandable that in the second wearing state, the direction of the opening formed after the first connecting section 131 is bent does not have to be opposite to the opening formed after the first connecting section 131 is bent in the first wearing state, as long as the sound-emitting part 12 can be moved to cover at least part of the ear hole area.

[0095] Specifically, referring to Figures 5 and 6 , the various outer surfaces of the ear clip portion 13 are defined as follows: the surface of the ear clip portion 13 facing the user's ear is defined as the inner surface. The surface of the ear clip portion 13 facing away from the user's ear is defined as the outer surface. It can be understood that the first connecting section 131 of the ear clip portion 13 includes a first outer surface 1312 facing away from the ear, and the second connecting section 132 includes a second outer surface 1322 facing away from the ear. The absolute value of the first average curvature radius of the first connecting section 131 is greater than the absolute value of the second average curvature radius of the second connecting section 132. This can be understood as the absolute value of the first average curvature radius of the first outer surface 1312 is greater than the absolute value of the second average curvature radius of the second outer surface 1322.

[0096] It should be noted that the radius of curvature of each point of the first connecting segment 131 may gradually change from the end connected to the second connecting segment 132 toward the end connected to the sound-emitting portion 12, such as gradually decreasing, gradually increasing, first gradually increasing and then gradually decreasing, or first gradually decreasing and then gradually increasing. Based on this, for ease of understanding, the first average curvature radius is used in the embodiment of the present application to represent the curvature radius of the first connecting segment 131.

[0097] Similarly, the radius of curvature of each point of the second connecting segment 132 can gradually change from the end connected to the first connecting segment 131 toward the end connected to the balancing portion 11, such as gradually decreasing, gradually increasing, first gradually increasing and then gradually decreasing, or first gradually decreasing and then gradually increasing. For ease of understanding, the second average radius of curvature is used in the present embodiment to represent the radius of curvature of the second connecting segment 132.

[0098] Exemplarily, in the first wearing state, the absolute value of the first average radius of curvature ranges from 10 mm to 40 mm, and the absolute value of the second average radius of curvature ranges from 3 mm to 10 mm. Specifically, in the first wearing state, the absolute value of the first average radius of curvature of the first outer surface 1312 of the first connecting segment 131 ranges from 10 mm to 40 mm, such as any value between 10 mm and 40 mm, including 10 mm and 40 mm. The absolute value of the second average radius of curvature of the second outer surface 1322 of the second connecting segment 132 ranges from 3 mm to 10 mm, such as any value between 3 mm and 10 mm, including 3 mm and 10 mm. This application is not limited here. In this way, under this average radius of curvature, the earphone 10 can be stably worn on the user's ear.

[0099] In the second wearing state, the absolute value of the first average radius of curvature is in the range of 10 mm to 40 mm, and the absolute value of the second average radius of curvature is in the range of 3 mm to 10 mm. Specifically, in the second wearing state, the absolute value of the first average curvature of the first outer surface 1312 of the first connecting segment 131 is in the range of 10 mm to 40 mm, such as any value between 10 mm and 40 mm, including 10 mm and 40 mm. The absolute value of the second average radius of curvature of the second outer surface 1322 of the second connecting segment 132 is in the range of 3 mm to 10 mm, such as any value between 3 mm and 10 mm, including 3 mm and 10 mm. This application is not limited here. In this way, under this average curvature radius, the sound-emitting portion 12 of the earphone 10 can be stably inserted into the ear hole, and the earphone 10 can also be stably worn on the user's ear.

[0100] In the first wearing state, the thickness of the balancing portion 11, as measured from the end closest to the ear toward the end further from the ear, is positively correlated with the absolute value of the second average radius of curvature of the second connecting segment 132. That is, in the first wearing state, the greater the thickness of the balancing portion 11, as measured from the end closest to the ear toward the end further from the ear, the less curvature of the second connecting segment 132. This ensures that when the earphones 10 are worn on the user's ears, they do not place excessive pressure on the ears, enhancing wearing comfort.

[0101] The above is a description of the overall structure of the earphone 10. The specific structure of the adjustment member 14 and its related components will be described in detail below with reference to the accompanying drawings.

[0102] It can be understood that the adjustment member 14 is a structural component for adjusting the bending state of the ear clip part 13, which can be arranged in the ear clip part 13. For example, the ear clip part 13 is made of soft material, and the adjustment member 14 is wrapped in the ear clip part 13 through an injection molding process.

[0103] It is also understandable that when the earphone 10 switches between the first wearing state and the second wearing state, it is not necessary to adjust the entire bending state of the ear clip portion 13. It can be achieved by adjusting only a portion of the ear clip portion 13 to achieve the switching of the earphone 10 between the first wearing state and the second wearing state. Therefore, the length of the adjustment member 14 can be set to at least one-fifth of the length of the ear clip portion 13, so as to enable the earphone 10 to switch between the first wearing state and the second wearing state. For example, the length of the adjustment member 14 can be one-fifth, one-quarter, one-third, one-half, or equal to the length of the ear clip portion 13. This is not limited in the present application.

[0104] It can also be understood that, as shown in Figures 5 and 6, the ear clip portion 13 includes a first connecting segment 131 and a second connecting segment 132 that are connected to each other. The first connecting segment 131 is connected to the sound-emitting portion 12, and the second connecting segment 132 is connected to the balancing portion 11. The adjustment member 14 is provided at least on the first connecting segment 131 to adjust the bending state of the first connecting segment 131, so that the earphone 10 can be switched between the first wearing state and the second wearing state.

[0105] In some embodiments, referring to Figures 5 and 6 , the adjustment member 14 includes at least one hinge assembly 141, which includes at least two hinges 1411. The at least two hinges 1411 are hinged in sequence along the bending direction of the ear clip portion 13. When the angle between two adjacent hinges 1411 is adjusted, the bending state of the ear clip portion 13 can be adjusted and maintained in the adjusted bending state. In this way, by adjusting the angle between two adjacent hinges 1411 in the hinge assembly 141, the bending state of the ear clip portion 13 can be adjusted and maintained in the adjusted bending state, thereby enabling the earphone 10 to switch between the first wearing state and the second wearing state as needed.

[0106] It is understandable that the adjustment member 14 may include only one set of hinge groups 141. As shown in Figures 5 and 6, one set of hinge groups 141 may be located only in the first connecting section 131. As shown in Figures 7 and 8, Figure 7 is a second structural schematic diagram of the earphone provided in an embodiment of the present application, and Figure 8 is a structural schematic diagram of the earphone shown in Figure 7 in another state. It is understandable that the hinge group 141 shown in Figures 7 and 8 is generally embedded in the ear clip portion 13 and is not visible. For the sake of convenience of description, it is illustrated as being externally visible, for example, part of the material covering the hinge group 141 is removed. One set of hinge groups 141 may also be located in the first connecting section 131 and at least part of the hinge 1411 extends to the second connecting section 132. It can also be understood that the specific structure of the hinge in Figures 7 and 8 is only for illustration. The number of hinges 1411 in Figures 7 and 8 is three. Of course, the number of hinges 1411 in Figures 7 and 8 can also be two. As long as the size of the hinge 1411 is designed to be large enough, at least part of the hinge 1411 can extend to the second connecting section 132.

[0107] It can also be understood that the adjustment member 14 can also include multiple hinge groups 141, such as two or more hinge groups 141, wherein all hinge groups 141 can be located in the first connecting section 131, or some hinge groups 141 can be located in the first connecting section 131, and other hinge groups 141 can be located in the second connecting section 132. This application does not impose any restrictions here.

[0108] The angle between two adjacent hinges 1411 in the hinge assembly 141 can be adjusted to any value between 90 degrees and 270 degrees. As shown in FIG9 , FIG9 is a schematic diagram of the rotational state of the hinge assembly provided in an embodiment of the present application. The angle between two adjacent hinges 1411 can be adjusted from angle α1 to angle α2. It is understood that the dotted line in FIG9 represents another state of the hinge 1411 after adjusting the corresponding angle.

[0109] In order to facilitate the hinge connection between the hinges 1411, please refer to Figure 6. One of the hinges in the hinge group 141, such as the first hinge 1411a, is provided with a first hinge portion 14111, and the adjacent hinge, such as the second hinge 1411b, is provided with a second hinge portion 14112. The first hinge portion 14111 and the second hinge portion 14112 are hinged through the first rotating shaft 1412.

[0110] For example, please continue to refer to Figure 6. The hinge 1411 may include two, namely a first hinge 1411a and a second hinge 1411b. The first hinge 1411a is provided with a first hinge portion 14111, and the second hinge 1411b is provided with a second hinge portion 14112. The first hinge portion 14111 and the second hinge portion 14112 are hinged through a first rotating shaft 1412.

[0111] For example, referring to Figures 7 and 8, the hinge 1411 may include three, namely a first hinge 1411a, a second hinge 1411b and a third hinge 1411c, and the second hinge 1411b is located between the first hinge 1411a and the second hinge 1411c. It can be understood that one end of the second hinge 1411b is hinged to the first hinge 1411a, and the other end of the second hinge 1411b is hinged to the third hinge 1411c.

[0112] For example, please refer to Figures 10 and 11. Figure 10 is a schematic diagram of the third structure of the earphones provided in an embodiment of the present application, and Figure 11 is a schematic diagram of the structure of the earphones shown in Figure 10 in another state. It is understood that the hinge assembly 141 shown in Figures 10 and 11 is generally embedded within the ear clip portion 13 and is not visible. For ease of description, it is illustrated as being visible, for example, by removing some of the material covering the hinge assembly 141. The hinges 1411 may include four hinges 1411, which are hingedly connected in sequence to form the hinge assembly 141.

[0113] It is understandable that the number of hinges 1411 can be set according to actual conditions, and this application does not impose any restrictions thereon.

[0114] In some embodiments, please refer to Figure 12, which is a schematic diagram of a first structural embodiment of a hinge assembly provided by an embodiment of the present application. To provide greater stability during rotation of the hinge 1411, the first hinge portion 14111 of one hinge 1411 includes a first sub-portion 14111a and a second sub-portion 14111b spaced apart along the axial direction. The second hinge portion 14112 of the adjacent hinge 1411 is disposed between the first sub-portion 14111a and the second sub-portion 14111b and is hingedly connected via the first rotating shaft 1412.

[0115] In some embodiments, a first damping layer may be interposed between the first rotating shaft 1412 and the first hinge portion 14111. Alternatively, a second damping layer may be interposed between the first rotating shaft 1412 and the second hinge portion 14112. Alternatively, damping layers may be interposed between both the first rotating shaft 1412 and the first hinge portion 14111 and the second hinge portion 14112. This ensures that the hinge 1411 can remain at any angle during rotation, allowing the earphone 10 to remain in its adjusted state. Furthermore, this arrangement allows for stepless, or continuous, angle adjustment. That is, within a certain range of motion, the hinge 1411 can remain at any position between the minimum and maximum angles, without pre-set positions. The hinge 1411's rotation is continuous and variable, not abrupt, but rather relatively smooth within a range. This allows for greater precision in the position adjustment of the hinge 1411, enabling better adaptation to users of varying ear sizes.

[0116] In order to enable the hinges 1411 to rotate within a certain rotation range, the hinge assembly 141 may further include a limiting structure 1413 , and the limiting structure 1413 is used to limit the maximum rotation angle between adjacent hinges 1411 .

[0117] In some embodiments, please refer to FIG13 , which is a schematic diagram of a second structure of a hinge assembly provided in an embodiment of the present application. A limiting structure 1413 is provided between adjacent hinges 1411 .

[0118] Exemplarily, the limiting structure 1413 includes a first limiting protrusion 14131 and a first limiting groove 14132. The first limiting protrusion 14131 is arranged on one of the hinges 1411, and the first limiting groove 14132 is arranged on another adjacent hinge 1411. The first limiting protrusion 14131 and the first limiting groove 14132 cooperate to limit the maximum rotation angle between adjacent hinges 1411.

[0119] Specifically, the first limiting groove 14132 is arranged on the first hinge portion 14111 of one of the hinges 1411, and the first limiting protrusion 14131 is arranged on the adjacent hinge 1411 and extends into the first limiting groove 14132. When the hinge 1411 is rotated to a certain angle, the first limiting protrusion 14131 can be abutted against the groove wall of the first limiting groove 14132, thereby limiting the rotation angle between adjacent hinges 1411.

[0120] In other embodiments, please refer to Figure 14, which is a schematic diagram of a third structure of a hinge assembly provided in an embodiment of the present application. A limiting structure 1413 is provided between the first rotating shaft 1412 and a first hinge portion 14111 that cooperates with the first rotating shaft 1412.

[0121] Illustratively, the limiting structure 1413 includes a second limiting protrusion 14133 and a second limiting groove 14134. The second limiting protrusion 14133 is provided on the first rotating shaft 1412, and the second limiting groove 14134 is provided on the first hinge portion 14111 that cooperates with the first rotating shaft 1412. The second limiting protrusion 14133 extends into the second limiting groove 14134. The second limiting protrusion 14133 cooperates with the second limiting groove 14134 to limit the maximum rotation angle between adjacent hinges 1411. It is understandable that when the hinge 1411 rotates to a certain angle, the second limiting protrusion 14133 can abut against the groove wall of the second limiting groove 14134, thereby limiting the rotation angle between adjacent hinges 1411.

[0122] It is understandable that since the adjustment member 14 can be wrapped in the ear clip portion 13 through an injection molding process, based on this, in order to make the adjustment member 14 and the ear clip portion 13 more tightly combined, a hole 14113 can be provided on the adjustment member 14, for example, a hole 14113 can be provided on the hinge 1411. In this way, when the hinge 1411 is wrapped in the ear clip portion 13 through the injection molding process, the molding material can partially flow into the hole 14113, thereby improving the tightness of the connection between the ear clip portion 13 and the hinge 1411. At the same time, the weight of the adjustment member 14 can be reduced, making the overall weight of the ear clip portion 13 lighter. Among them, the hole 14113 can be a through hole or a blind hole, and this application does not limit this.

[0123] It should be noted that both the hinge and the ear clip portion 13 have a certain thickness. If the hinge is too thick and the ear clip portion 13 is too thin, the hinge will deform the appearance of the ear clip portion 13, affecting its appearance. If the hinge is too thin and the ear clip portion 13 is too thick, the hinge may not be able to adjust the bending degree of the ear clip portion 13, or the adjustment effect may be poor. Based on this, in some embodiments, the ratio between the maximum thickness of the hinge and the maximum thickness of the ear clip portion 13 can be set between 0.3 and 0.7. For example, the maximum thickness of the hinge is the thickness at the hinge axis, and its value range can be between 1.5 mm and 3 mm, including any value between 1.5 mm and 3 mm. The thickness of the ear clip portion 13 can range from 2.5 mm to 5 mm, including any value between 2.5 mm and 5 mm. The thickness of the hinge is smaller than the thickness of the ear clip portion 13. The thickness of the ear clip portion 13 includes the thickness of the ear clip portion's wrapping layer and the hinge and other structures therein. In other words, the overall thickness represents the thickness of the ear clip portion 13. Thus, the aforementioned thickness setting does not affect the appearance of the ear clip portion 13, nor does it affect the ability to adjust the curvature of the ear clip portion 13.

[0124] In order to better adjust the bending state of the second connecting section of the ear clip portion, in some embodiments, please refer to Figure 15, which is a structural schematic diagram of the deformable member provided in an embodiment of the present application when installed on the second connecting section. It can be understood that the deformable member 142 shown in Figure 15 is generally embedded in the second connecting section 132 and is not visible. For ease of description, it is illustrated as being visible externally, for example, by removing part of the material covering the deformable member 142. The adjustment member 14 may also include a deformable member 142, which is disposed on the second connecting section 132 and is used to adjust the bending state of the second connecting section 132. The deformable member 142 can be a hinge structure, a spring structure, a metal sheet or a metal wire, etc., which can be deformed to adjust the bending state of the second connecting section 132. In this embodiment, the deformable member 142 adopts a spring structure.

[0125] Please refer to Figures 16 and 17. Figure 16 illustrates the deformable member in Figure 15 in its first state, and Figure 17 illustrates the deformable member in its second state. In the first wearing state, the deformable member 142 bends toward the ear to form a first curved shape 1421. In the second wearing state, the deformable member 142 bends away from the ear to form a second curved shape 1422. The orientation of the opening formed by the first curved shape 1421 is opposite to that of the opening formed by the second curved shape 1422. In this way, the deformable member 142 can change the bending state of the second connecting section 132 to better meet the user's adjustment needs.

[0126] It can be understood that the first bending shape 1421 and the second bending shape 1422 can be the same or different.

[0127] The so-called "the first bending shape and the second bending shape of the deformable member 142 can be the same" can be understood as: although the bending directions of the deformable member 142 are different, the shapes after bending are the same or symmetrical, and the geometric dimensions (such as length, width, tangent angle, average curvature radius, etc.) are the same. It should be noted that the "same" mentioned in the embodiments of the present application means: completely identical or approximately the same. For example, referring to Figures 16 and 17, the deformable member 142 is bent in opposite directions to form arcs with opposite opening directions. In other words, in the embodiments shown in Figures 16 and 17, the first bending shape and the second bending shape are both arcs, and their lengths, widths, tangent angles, average curvature radius, etc. are approximately the same, so the two shapes are basically the same or symmetrical. However, it should be noted that the first bending shape and the second bending shape here are not limited to arcs. The arc is only a special curve shape. It can also be other geometric curves that can achieve at least two identical bending shapes, free curves, or a combination of curves and straight lines.

[0128] The aforementioned "the first and second bend shapes of the deformable member 142 can be different" can be understood as: the deformable member 142 has different or slightly different shapes after bending, or at least one of its geometric dimensions (e.g., length, width, tangent angle, average radius of curvature, etc.) is different or slightly different. Examples of situations where "the first and second bend shapes can be different" include: both having roughly arc-shaped profiles but different average radii of curvature, or both having significantly different curved profiles but the same or different average radii of curvature. Similarly, the first and second bend shapes can be geometric curves, free-form curves, or a combination of curves and straight lines, capable of achieving at least two different bending shapes.

[0129] In reality, the so-called different directions cannot be limited to just opposite directions, and the various bending shapes cannot be limited to just the first bending shape shown in Figure 16 and the second bending shape shown in Figure 17. In other embodiments, the deformable member 142 can also be designed to bend at other angles, thereby being able to be bent into more bending shapes, further providing a wider range of usage postures for the ear clip. Therefore, the deformable member 142 provided in the embodiment of the present application can be a flexible sheet that can be freely designed to form different shapes after being deformed according to different bending methods or deformation methods, thereby providing a wider range of usage postures.

[0130] Please refer to Figure 18, which shows a projection view of the deformable member on a side projection surface. The surface of the deformable member 142 is configured as an arc. The arc is projected onto the side projection surface as an arc 1423. The tangent angle β of the arc 1423 is between 15 and 45 degrees. As will be appreciated, the arc 1423 includes a first end 14231 and a second end 14232. A first line segment 1424 connects the first end 14231 and the second end 14232. A tangent 1425 of the arc 1423 is formed at the second end 14232. The arc 1423 is located within the angle formed by the first line segment 1424 and the tangent 1425. The tangent angle β is the angle formed by the first line segment 1424 and the tangent 1425. As the tangent angle β of the arc changes, the curvature of the arc 1423 also changes. It can also be understood that in the first wearing state and the second wearing state, the chord cutting angle can be the same (can be approximately the same) or different (for example, slightly different or significantly different).

[0131] It should be noted that the so-called "arc" can be the inner arc formed by the deformable member 142 on the side projection surface, or it can be the outer arc formed by the deformable member 142 on the side projection surface. Usually, the projection of the deformable member 142 on the side projection surface will indeed form an inner arc and an outer arc, but since the deformable member 142 provided in the embodiment of the present application is a thin sheet, the inner arc and the outer arc have approximately the same tangent angle, so this article does not need to distinguish between the inner arc and the outer arc, but uses "arc" as a general term for the two. However, in other embodiments, if the deformable member 142 is not a thin sheet, and its thickness is sufficient to make the tangent angle of the inner arc and the outer arc different, then the tangent angle β (15 degrees to 45 degrees) of the above-mentioned arc 1423 can refer to the tangent angle of the outer arc.

[0132] Specifically, the deformable member 142 is a flexible sheet and includes a first flexible arm 14261, a second flexible arm 14262, a first connecting portion 1427, a second connecting portion 1428, and an opening 1429. The first flexible arm 14261 and the second flexible arm 14262 are spaced apart around the opening 1429. When the deformable member 142 is disposed on the second connecting segment 132, the length of the deformable member 142 is substantially aligned with the length of the second connecting segment 132, and the width of the deformable member 142 is substantially aligned with the width of the second connecting segment 132. The first flexible arm 14261 and the second flexible arm 14262 of the deformable member 142 are arranged and spaced apart along the width of the deformable member 142. The opening 1429 not only reduces weight but also disperses external forces, preventing the deformable member 142 from unexpectedly reversing. For example, it can prevent the deformable member 142 from bending in the opposite direction upon even the slightest accidental contact.

[0133] The first connecting portion 1427 is fixedly connected to one end of the first flexible arm 14261 and the second flexible arm 14262. The term "fixed connection" is used in contrast to a "movable connection." In the embodiments of the present application, a fixed connection refers to a one-piece structure. For example, the first connecting portion 1427 and the first flexible arm 14261 and the second flexible arm 14262 are a one-piece structure, rather than a two-piece structure connected together. In other embodiments, the fixed connection can also be other types of connections, such as welding.

[0134] The second connecting portion 1428 movably connects the other ends of the first flexible arm 14261 and the second flexible arm 14262 via a movable riveting connection. The area of ​​the first connecting portion 1427 is larger than the area of ​​the second connecting portion 1428, causing the deformable member 142 to form a contracted shape at the second connecting portion 1428. This facilitates the formation of a movable connection at the second connecting portion 1428 and facilitates the bending operation of the deformable member 142 near the second connecting portion 1428, thereby achieving a stable bending state. Because the second connecting portion 1428 movably connects the other ends of the first flexible arm 14261 and the second flexible arm 14262 via a movable riveting connection, when the bending state of the deformable member 142 changes, the second connecting portion 1428 has room to move, thereby eliminating the deformation stress generated by the deformable member 142 after deformation. This allows the deformable member 142 to maintain a stable state after deformation without resetting, thereby improving the stability of the deformable member 142 after deformation.

[0135] Example 2

[0136] Please refer to Figure 19, which is a schematic diagram of one structure of the human ear 10 to which the ear clip part and the earphone provided in the embodiment of the present application are applicable. As shown in Figure 19, the user's ear 10 may include the helix 11, the scaphoid 12, the antihelix 13, the triangular fossa 14, the concha 15, the ear foramen 16, the tragus 17, and the earlobe 18, wherein the concha 15 may include the scaphoid 151 and the cavum concha 152, and the ear foramen 16 may also be referred to as the external auditory canal or the opening of the external auditory meatus. In addition, the "front side of the ear" in this application is a concept relative to the "back side of the ear", and the "front side of the ear" refers to the side of the ear 10 away from the head, and the "back side of the ear" refers to the side of the ear 10 facing the head.

[0137] The ear clip portion 20 provided in the embodiment of the present application can provide a variety of usage postures, such as at least two usage postures. Accordingly, the earphone 30 provided in the embodiment of the present application can achieve a variety of wearing states, such as at least two wearing states, by using the ear clip portion 20. In the description of the present application, "multiple" means two or more, unless otherwise clearly and specifically defined. The "wearing state" of the present application refers to a stable wearing state when the earphone 30 is stably worn on the ear 10 of the human body. Of course, due to individual differences among users, there may be certain differences in the actual wearing state of the earphone 30.

[0138] Please first refer to Figure 20. The earphone 30 provided in this embodiment of the present application includes a sound-emitting part 31, a balancing part 32 and an ear clip part 20. The ear clip part 20 connects the sound-emitting part 31 and the balancing part 32.

[0139] Please refer to Figures 21 to 23 for a simulated wearing state of the earphone 30 provided in the embodiment of the present application on the ear 10. In the first wearing state (see Figure 21), the sound-producing portion 31 is located in front of the ear 10, and the balancing portion 32 is located in the back of the ear 10 (see Figure 23). The sound-producing portion 31 and the balancing portion 32 clamp the ear 10 via the ear clip 20. In the second wearing state (see Figure 22), the sound-producing portion 31 changes position under the influence of the ear clip 20, and the balancing portion 32 can be located in the back of the ear 10 or at the edge of the helix 11. The so-called "position change" can be: the entirety of the sound-producing portion 31, a portion of its surface, or a portion of its structure moves toward the ear opening 16 of the ear 10, and the sound-producing portion 31 at least covers a portion of the ear opening 16 area. The specific changes will be further explained later.

[0140] The structure of the ear clip portion 20 provided in the embodiment of the present application and its various usage postures will be described in detail below using multiple embodiments, and then the detailed structure of the earphone 30 provided in the embodiment of the present application and its various wearing states will be described.

[0141] Please refer to the structural schematic diagrams of the ear clip portion 20 provided in the second embodiment of the present application shown in Figures 24 and 25, wherein Figure 24 shows the first usage posture of the ear clip portion 20, and Figure 25 shows the second usage posture of the ear clip portion 20. The ear clip portion 20 provided in the second embodiment of the present application includes a main body 21 and at least one deformable member 22; the main body 21 has a first end 201 and a second end 202, and the deformable member 22 is disposed in the main body 21 and is close to the first end 201. The deformable member 22 has a first bent shape (see Figure 26) and a second bent shape (see Figure 27), corresponding to the first usage posture (see Figure 24) and the second usage posture (see Figure 25) of the ear clip portion 20, respectively. Specifically, in the first usage posture, the deformable member 22 is bent toward the ear 10 to form a first bent shape, and the first end portion 201 is located at a first position on the front side of the ear 10; in the second usage posture, the deformable member 22 is bent away from the ear 10 to form a second bent shape, and the first end portion 201 is located at a second position on the front side of the ear 10; wherein, the first bending shape and the second bending shape of the deformable member 22 may be the same or different, and the first position and the second position of the first end portion 201 are different.

[0142] The ear clip portion 20 provided in the embodiment of the present application is provided with a deformable member 22. The deformable member 22 is configured to form at least two bending shapes, which can adjust the position of the first end portion 201 on the ear portion 10, allowing the ear clip portion 20 to have at least two usage postures. Furthermore, by adjusting the shape of the deformable member 22 and changing the usage posture of the deformable member 22, the present application can enable the earphone 30 to have multiple wearing positions, thereby solving the problem of existing earphones having a single usage posture.

[0143] It should be noted that the aforementioned "first and second positions of the first end portion 201 are different" can be understood as meaning that the position of the first end portion 201 relative to the ear portion 10 has changed due to a change in the relative position of the first end portion 201 and the second end portion 202. One specific example of a change in the relative position of the first end portion 201 and the second end portion 202 is a change in the distance between the first end portion 201 and the second end portion 202. For example, in the first usage posture, the first end portion 201 and the second end portion 202 have a first distance 203, as shown in FIG. 24 ; in the second usage posture, the first end portion 201 and the second end portion 202 have a second distance 204, as shown in FIG. 25 ; wherein the second distance 204 is greater than the first distance 203. Therefore, when the ear clip portion 20 switches from the first usage posture to the second usage posture, the first end portion 201 moves away from the second end portion 202.

[0144] However, the relative position change between the first end 201 and the second end 202 is not limited to the above-mentioned distance change. It can also be that the distance between the two remains unchanged but the orientation changes, thereby changing the relative position between the two, or both the distance and orientation between the two change, thereby changing the relative position between the two.

[0145] The so-called "the first bending shape and the second bending shape of the deformable member 22 can be the same" can be understood as: although the bending directions of the deformable member 22 are different, the shapes after bending are the same or symmetrical, and the geometric dimensions (such as length, width, tangent angle, average radius of curvature, etc.) are the same. It should be noted that the same mentioned in the embodiments of the present application means: completely the same or approximately the same. For example, referring to Figures 26 and 27, the deformable member 22 is bent in opposite directions to form arcs with opposite opening directions. In other words, in the embodiments shown in Figures 26 and 27, the first bending shape and the second bending shape are both arcs, and their lengths, widths, tangent angles, average radius of curvature, etc. are approximately the same, so the two shapes are basically the same or symmetrical. However, it should be noted that the first bending shape and the second bending shape here are not limited to arcs. The arc is only a special curve shape. It can also be other geometric curves that can achieve at least two identical bending shapes, free curves, or a combination of curves and straight lines.

[0146] The aforementioned "the first and second bend shapes of the deformable member 22 can be different" can be understood as: the deformable member 22 has different or slightly different shapes after bending, or at least one of its geometric dimensions (e.g., length, width, tangent angle, average radius of curvature, etc.) is different or slightly different. Examples of situations where "the first and second bend shapes can be different" include: both having roughly arc-shaped profiles but different average radii of curvature, or both having significantly different curved profiles but the same or different average radii of curvature. Similarly, the first and second bend shapes can be geometric curves, free-form curves, or a combination of curves and straight lines that can achieve at least two different bending shapes.

[0147] The ear clip portion 20 provided in the second embodiment of the present application is further provided with a semi-enclosed clamping space 23, as shown in Figures 24 and 25. When the ear clip portion 20 clamps the ear portion 10, the clamping space 23 provides space for the ear portion 10. When the deformable member 22 is bent toward the clamping space 23, the deformable member 22 forms a first bent shape. When the deformable member 22 is bent away from the clamping space 23, the deformable member 22 forms a second bent shape.

[0148] The detailed structure of the ear clip portion 20 provided in the second embodiment of the present application will be described in detail below.

[0149] Referring again to Figures 24 and 25 , the main body 21 provided in the second embodiment of the present application is curved along the length direction L1. This curved design allows the main body 21 to maintain its elasticity, enabling the elastic opening and closing of the ear clip 20, thereby ensuring that the ear clip 20 can be clamped or hung on the ear 10. Furthermore, through the curved design, the main body 21 bends around to form a clamping space 23 for the ear clip 20.

[0150] Furthermore, the main body 21 has a first average radius of curvature near the first end 201, and a second average radius of curvature near the second end 202. In different embodiments, the magnitudes of the first and second average radii of curvature can be set according to actual needs and can also be adjusted according to different usage postures. For example, in one embodiment, in the first usage posture, the first and second average radii of curvature can be set to be approximately the same, so that the first and second ends 201 and 202 can be symmetrically clamped to the front and back sides of the ear 10. In the second usage posture, the first average radius of curvature can be greater than the second average radius of curvature. By configuring the main body 21 so that the curvature near the second end 202 is significantly greater than the curvature near the first end 201, the second end 202 can provide a greater sense of adhesion, fit, or clamping force to the back side of the ear 10, thereby reducing the pressure from the first end 201 on the front side of the ear 10. Of course, in other embodiments, in order to meet the needs of other functions or other usage scenarios proposed by users, in the first usage posture and the second usage posture, the first average curvature radius and the second average curvature radius of the main body 21 can also be selected from different schemes than the above.

[0151] In the embodiment of the present application, the ranges of the first average curvature radius and the second average curvature radius can be set as follows: in the first use posture, the first average curvature radius is 10mm to 40mm, and the second average curvature radius is 3mm to 10mm; in the second use posture, the first average curvature radius is 10mm to 40mm, and the second average curvature radius is 3mm to 10mm. The specific values ​​can be selected based on the fit between the ear clip portion 20 and the ear portion 10 to further optimize wearing comfort and stability, and are not limited here.

[0152] The main body 21 provided in the embodiment of the present application is made of a soft material. The soft material can not only adapt its shape according to different postures of use, but also achieve a skin-friendly effect. The so-called soft material can have the characteristics of an elastic material, thereby increasing the sense of adhesion between the ear clip 20 and the ear 10, making it more stable to wear. The so-called soft material can also have the characteristics of an ultra-light material, which can make it easier and more comfortable for the user to wear. Of course, the so-called soft material can have the characteristics of elasticity and ultra-lightness at the same time, thereby further providing more advantages for the ear clip 20.

[0153] In the first usage posture, as shown in FIG24 , the main body 21 is generally C-shaped or U-shaped, with the first end 201 located in front of the ear 10 and the second end 202 located in back of the ear 10. Because the main body 21 is arched to conform to the shape of the helix 11 of the ear 10 and adhere to the ear 10, the first end 201 and the second end 202 can be brought together and elastically opened and closed, forming a clamping position on the ear 10. In the second usage posture, as shown in FIG25 , the main body 21 is L-shaped or hook-shaped, with the first end 201 located in front of the ear 10 and the second end 202 located in back of the ear 10, or alternatively, at the edge of the helix 11. In other words, in the second usage posture, the position of the second end 202 can be appropriately adjusted based on the position of the first end 201, ensuring that the balance portion 32 of the earphone 30 is hooked on the ear 10, or as long as the entire earphone 30 is hooked on or clamped to the ear 10. A detailed description will be given later when describing the balancing part 32 .

[0154] Referring to Figures 26, 27, and 28, the deformable member 22 provided in the second embodiment of the present application is a flexible sheet, such as a metal sheet, a flexible sheet other than a metal sheet, or a deformable sheet other than a flexible sheet. More specifically, in this embodiment of the present application, the deformable member 22 can be a metal spring or a nickel-titanium alloy spring. Not only can it be bent and deformed, it can also be configured as an antenna for the earphone 30. The deformable member 22 provided in this embodiment of the present application can be bent in different directions into a variety of shapes. For example, it can be bent in opposite directions into two roughly symmetrical shapes (a first bending shape and a second bending shape). In fact, the so-called different directions are not limited to opposite directions, and the various bending shapes are not limited to the first bending shape shown in Figure 26 and the second bending shape shown in Figure 27. In other embodiments, the deformable member 22 can also be designed to bend at other angles, thereby allowing it to be bent into a variety of shapes, further providing a wider range of usage postures for the ear clip 20. Therefore, the deformable member 22 provided in the embodiment of the present application is a flexible sheet, which can be freely designed to form different shapes after being deformed in different bending methods or deformation methods, so as to provide more usage postures.

[0155] As shown in FIG29 , the surface of the deformable member 22 provided in the second embodiment of the present application is configured as a curved surface. This curved surface projects as an arc 220 in side projection, with a tangent angle A of 15 to 45 degrees. In the first and second usage postures, the tangent angle A can be the same (can be substantially the same) or different (e.g., slightly different or significantly different). Specifically, the first and second curved shapes of the deformable member 22 provided in the second embodiment of the present application, as shown in FIG26 and FIG27 , have arc openings in opposite directions. For example, the opening of the first curved shape of the deformable member 22 faces the clamping space 23 of the ear clip 20, while the opening of the second curved shape of the deformable member 22 faces away from the clamping space 23 of the ear clip 20. However, in both the first and second curved shapes, the surface of the deformable member 22 can project as an arc 220 in side projection, and the tangent angle A of the arc 220 corresponding to the two curved shapes can be the same or different. In the second embodiment of the present application shown in FIG. 26 and FIG. 27 , the chord angles A of the corresponding arcs 220 formed by projecting the first bending shape and the second bending shape of the deformable member 22 on the side projection surface are the same.

[0156] It should be noted that the so-called "arc" can be the inner arc formed by the deformable member 22 on the side projection surface, or it can be the outer arc formed by the deformable member 22 on the side projection surface. Usually, the projection of the deformable member 22 on the side projection surface will indeed form an inner arc and an outer arc, but since the deformable member 22 provided in the embodiment of the present application is a thin sheet, the inner arc and the outer arc have approximately the same tangent angle, so this article does not need to distinguish between the inner arc and the outer arc, but uses "arc" as a general term for the two. However, in other embodiments, if the deformable member 22 is not a thin sheet, and its thickness is sufficient to make the tangent angles of the inner arc and the outer arc different, then the tangent angle A (15 degrees to 45 degrees) of the above-mentioned arc 220 can refer to the tangent angle of the outer arc.

[0157] The deformable member 22 provided in the embodiment of the present application can be laid throughout the main body 21 along the length direction L1 of the main body 21, or can be laid in a portion of the main body 21. Specifically, the length of the deformable member 22 provided in the embodiment of the present application is at least one-fifth of the length of the main body 21. In this way, when the deformable member 22 switches between the first bending shape and the second bending shape, it will cause a significant change in the position of the first end portion 201, thereby bringing about a variety of usage postures of the ear clip portion 20. From another perspective, if the length of the deformable member 22 is too small, then when the deformable member 22 switches from the first bending shape to the second bending shape, it will be difficult to cause a significant change in the position of the first end portion 201, thereby making it difficult to achieve the switching of the usage posture of the ear clip portion 20.

[0158] 24 and 25 , the length of the deformable member 22 provided in the second embodiment of the present application is substantially half the length of the main body 21, sufficient to change the position of the first end 201 relative to the second end 202, thereby providing at least two usage postures for the ear clip 20. Of course, in other embodiments, the length of the deformable member 22 can also be equal to the length of the main body 21.

[0159] 24 and 25 , the deformable member 22 provided in the second embodiment of the present application is configured to be disposed in the main body 21. Specifically, the deformable member 22 is embedded or buried in the main body 21 through an injection molding process, so that the main body 21 can change its posture as the shape of the deformable member 22 changes.

[0160] In other embodiments, the deformable member 22 may be disposed in the main body 21 not limited to injection molding. For example, as shown in FIG30 , a cavity 210 may be disposed in the main body 21, the cavity 210 being disposed along the length direction L1 of the main body 21, and the deformable member 22 being accommodated in the cavity 210. The length of the cavity 210 may even be designed to be greater than the length of the deformable member 22, so that the deformable member 22 can slide along the length direction L1 of the main body 21, thereby changing the shape of more areas on the ear clip 20 and providing the ear clip 20 with a variety of usage postures.

[0161] Specifically, the deformable member 22 can slide and reside at any position within the cavity 210. At each resting position, the deformable member 22 can bend in different directions to form at least two bent positions, as shown in Figures 8 and 9 . The main body 21 deforms in conjunction with the deformable member 22, thus enabling the ear clip 20 to have at least two different postures. Therefore, if the deformable member 22 can reside in two different positions, the ear clip 20 can have at least four different postures. If the deformable member 22 can reside in three different positions, the ear clip 20 can have at least six different postures. Similarly, a greater number of postures can be achieved. It is important to note that the term "different positions" refers to two positions with a large distance between them, or positions that are sufficient to cause the main body 21 to change position. For example, if the distance between the two resting positions is small, the positional change of the deformable member 22 after sliding is less noticeable, making it less likely to cause the main body 21 to change position, and thus failing to increase the number of postures for the ear clip 20. Therefore, as long as the distance between the positions where the deformable member 22 stops is large, the deformable member 22 will basically add at least two more usage postures for the ear clip portion 20. Alternatively, as long as the position where the deformable member 22 stops is sufficient to cause the main body 21 to change, the deformable member 22 will basically add at least two more usage postures for the ear clip portion 20. Thus, the deformable member 22 slidably disposed in the cavity 210 can provide the ear clip portion 20 with a wider range of usage postures.

[0162] In the embodiment of the present application, not only is the deformable member 22 configured to have two bending shapes, but a pivot structure (not shown) can also be provided at one end of the deformable member 22. The pivot structure can be used to change the position of the deformable member 22 in the main body 21, thereby changing the shape of the main body 21, thereby adding more usage postures for the ear clip portion 20.

[0163] In addition, the main body 21 provided in the embodiment of the present application may also be provided with a support structure (not shown) to increase the structural strength of the main body 21. The support structure may be a metal sheet, a metal wire, a titanium wire, etc., and the support structure may be provided throughout the main body 21 or in a localized position of the main body 21 to support the main body 21 and enhance its elasticity.

[0164] Although the embodiments of the present application illustrate only one deformable member 22 in the accompanying drawings, the ear clip portion 20 is not limited to having only one deformable member 22 and may also include two. For example, arranging the two deformable members 22 along the length of the main body 21 can expand the deformation area and provide the ear clip portion 20 with more possible postures. For example, when one deformable member 22 is deformed, the ear clip portion 20 can have at least two more postures; when the other deformable member 22 is deformed, the ear clip portion 20 can have at least four postures. In other embodiments of the present application, when two deformable members 22 are provided, the two deformable members 22 can be independently and spaced apart within the main body 21, independent of each other when they bend and deform. Of course, the two deformable members 22 can also be fixedly or flexibly connected within the main body 21. Furthermore, when two deformable members 22 are provided within the main body 21, the two deformable members 22 can have the same or different structures. In the main body 21 , the two deformation members 22 may also be arranged symmetrically or in other patterns.

[0165] Referring to Figures 26 and 27 , the deformable member 22 provided in the second embodiment of the present application is a flexible sheet. The deformable member 22 includes a first flexible arm 221, a second flexible arm 222, and an opening 223. The first flexible arm 221 and the second flexible arm 222 are spaced apart around the opening 223. When the deformable member 22 is attached to the main body 21, the length L2 of the deformable member 22 is substantially aligned with the length L1 of the main body 21, and the width W2 of the deformable member 22 is substantially aligned with the width W1 of the main body 21. The first flexible arm 221 and the second flexible arm 222 of the deformable member 22 are arranged and spaced apart along the width W2 of the deformable member 22. The opening 223 not only reduces weight, but also improves the fit between the deformable member 22 and the main body 21. It also disperses external forces, preventing the deformable member 22 from unintentionally bending, for example, by preventing the deformable member 22 from bending backwards even with the slightest touch.

[0166] When the deformable member 22 is in the first bent shape, as shown in FIG26 , the arcuate opening of the deformable member 22 faces the clamping space 23 of the ear clip portion 20 (see FIG24 ). When the deformable member 22 is in the second bent shape, as shown in FIG27 , the arcuate opening of the deformable member 22 faces away from the clamping space 23 of the ear clip portion 20 (see FIG25 ). Therefore, it can be seen that in this embodiment, the aforementioned "the deformable member 22 bends toward the ear portion 10 to form the first bent shape" means that the deformable member 22 bends toward the clamping space 23 to form the first bent shape, while "the deformable member 22 bends away from the ear portion 10 to form the second bent shape" means that the deformable member 22 bends away from the clamping space 23 to form the second bent shape.

[0167] In the second embodiment, the first flexible arm 221 and the second flexible arm 222 have substantially the same length, width, and curvature, thereby making the first and second bent shapes of the deformable member 22 substantially identical. For example, the first and second bent shapes of the deformable member 22 are both curved, and their average radius of curvature is in the range of 10 mm to 30 mm. In the second embodiment, because the first flexible arm 221 and the second flexible arm 222 have substantially the same dimensions, when the deformable member 22 is deformed into the first and second bent shapes, the stresses on the first and second flexible arms 221, 222 can offset each other, preventing the stresses on the two flexible arms 221, 222 from differing, thereby providing a stable bent shape. Of course, in other embodiments, users may require different postures based on different application scenarios. In this case, the first and second flexible arms 221, 222 can have different lengths, widths, or curvatures, thereby varying the bending direction and curvature of the first and second flexible arms 221, 222, thereby providing at least two different postures than those in this embodiment.

[0168] Referring to Figures 26 and 27, the deformable member 22 provided in the second embodiment of the present application further includes a first connecting portion 224, which is used to fixedly connect one end of the first flexible arm 221 and the second flexible arm 222. The so-called "fixed connection" is relative to the "movable connection". The fixed connection in the second embodiment of the present application refers to a one-piece structure, for example: the first connecting portion 224 and the first flexible arm 221 and the second flexible arm 222 are a one-piece structure, rather than a two-piece structure connected together. In other embodiments, the fixed connection can also be other types of connection, such as connection by welding.

[0169] Referring to Figures 26 and 27, the deformable member 22 provided in the second embodiment of the present application further includes a second connecting portion 225 for movably connecting the other ends of the first flexible arm 221 and the second flexible arm 222, and at the second connecting portion 225, there is a movable gap between the first flexible arm 221 and the second flexible arm 222. In the second embodiment of the present application, the second connecting portion 225 movably connects the first flexible arm 221 and the second flexible arm 222 by means of movable riveting, thereby forming a movable gap. The deformable member 22 provided in the second embodiment of the present application can preserve a certain amount of elastic potential energy for the two flexible arms 221 and 222 by providing a movable gap at the riveted joint, so that the two flexible arms 221 and 222 can maintain their deformed state. When there is no external force, the deformable member 22 will not be flipped, thereby obtaining two stable bending shapes.

[0170] In the second embodiment of the present application, the area of ​​the first connection portion 224 is larger than the area of ​​the second connection portion 225, so that the deformable member 22 forms a contracted shape at the second connection portion 225, which facilitates the formation of a movable connection at the second connection portion 225 and facilitates the bending operation of the deformable member 22 near the second connection portion 225, thereby achieving a stable bending state. In addition, since it is generally easier to bend the deformable member 22 by applying a bending force near the second connection portion 225 when bending the deformable member 22, when the deformable member 22 is disposed on the main body 21, the first connection portion 224 is positioned close to the first end portion 201 and the second connection portion 225 is positioned away from the first end portion 201. In this way, when bending the deformable member 22, the user does not need to operate the first connection portion 224 near the first end portion 201, but only needs to perform the bending operation at the second connection portion 225 away from the first end portion 201, thereby providing the user with more operating space.

[0171] As shown in FIG31 , the deformable member 22 provided in the second embodiment of the present application can also be modified. For example, the deformable member 22 can include a fixed joint 226 disposed on the first connecting portion 224 and protruding toward the first end portion 201 of the main body 21, for fixedly or electrically connecting to the earphone 30. For example, the fixed joint 226 can achieve a mechanical or electrical connection with the sound-emitting portion 31 of the earphone 30, and in particular, can be connected to the circuitry within the sound-emitting portion 31.

[0172] The following describes the ear clip and deformable member provided in a third embodiment of the present application. The ear clip provided in the third embodiment is designated by reference numeral 20a, the main body by reference numeral 21a, and the deformable member by reference numeral 22a. Specifically, elements or structures in the third embodiment share the same reference numerals as similar elements or structures in the second embodiment shown in Figures 24 to 31, with the addition of the suffix "a."

[0173] Please refer to the structural schematic diagrams of the deformable member 22a provided in the third embodiment of the present application shown in Figures 32 to 34, wherein Figure 32 shows the first bent shape of the deformable member 22a, Figure 33 shows the second bent shape of the deformable member 22a, and Figure 34 shows a comparative schematic diagram of the deformable member 22a in the first bent shape and the second bent shape. As shown in Figures 32 and 33, the deformable member 22a provided in the second embodiment of the present application is a flexible sheet, including a first flexible arm 221a, a second flexible arm 222a, and an opening 223a; the first flexible arm 221a and the second flexible arm 222a are spaced apart around the opening 223a. The deformable member 22a also includes a first connecting portion 224a for fixedly connecting one end of the first flexible arm 221a and the second flexible arm 222a. The deformable member 22a includes a second connecting portion 225a for fixedly connecting the other end of the first flexible arm 221a and the second flexible arm 222a.

[0174] The main difference between the deformable member 22a provided in the third embodiment of the present application and the deformable member 22 provided in the second embodiment of the present application is that the second connecting portion 225a of the deformable member 22a provided in the second embodiment of the present application is used to fixedly connect (non-movably connect) the other end of the first flexible arm 221a and the second flexible arm 222a.

[0175] Therefore, in the deformable member 22a provided in the third embodiment of the present application, the first flexible arm 221a, the second flexible arm 222a, the first connecting portion 224a, and the second connecting portion 225a can be a one-piece structure, and the entire deformable member 22a is directly punched out through a stamping process without the need for other steps. Of course, in other embodiments, the deformable member 22a provided in the second embodiment of the present application can also use other fixed connection means to achieve the first connecting portion 224a fixedly connected to one end of the first flexible arm 221a and the second flexible arm 222a, and the second connecting portion 225a fixedly connected to the other end of the first flexible arm 221a and the second flexible arm 222a.

[0176] Furthermore, in the deformable member 22a provided in the second embodiment of the present application, the width of the middle of the opening 223a is greater than the width of the ends of the opening 223a. This structure provides ample deformation space for the first flexible arm 221a and the second flexible arm 222a, preventing interference between the two during deformation or bending.

[0177] Aside from the aforementioned differences, the structural details and design parameters of the deformable member 22a provided in the third embodiment of the present application can be selectively configured with reference to the deformable member 22 provided in the second embodiment of the present application. In other words, the design requirements set forth above for the deformable member 22 provided in the second embodiment of the present application are also applicable to the deformable member 22a provided in the third embodiment of the present application. For example, the chord angle A, average radius of curvature, support structure, fixed joint 226, method of fixing the deformable member 22 to the main body 21, length ratio of the deformable member 22 to the main body 21, material, quantity, and other configuration requirements of the deformable member 22 provided in the second embodiment of the present application can all be applied to the deformable member 22a provided in the third embodiment of the present application.

[0178] Please refer to Figures 35 and 36. The ear clip portion 20a provided in the third embodiment of the present application can produce two usage postures according to the two bending shapes of the deformable part 22a, wherein Figure 35 is the first usage posture of the ear clip portion 20a provided in the second embodiment of the present application, and Figure 36 is the second usage posture of the ear clip portion 20a provided in the second embodiment of the present application.

[0179] Similarly, the design requirements for the ear clip portion 20 and its main body 21 provided in the second embodiment of the present application also apply to the ear clip portion 20a and its main body 21a provided in the third embodiment of the present application. For example, the first average curvature radius, second average curvature radius, shape, material, and other configuration requirements of the main body 21 provided in the second embodiment of the present application are all applicable to the main body 21a provided in the third embodiment of the present application.

[0180] Please refer to the structural schematic diagrams of the earphone 30 provided in the embodiment of the present application shown in Figures 37 to 40, wherein Figures 37 and 38 expose the changes of the deformable member 22 of the second embodiment in the ear clip portion 20 through partial cross-sectional views, and Figures 39 and 40 expose the changes of the deformable member 22a of the third embodiment in the ear clip portion 20a through partial cross-sectional views.

[0181] Please pay special attention to the markings in Figure 37. The earphone 30 provided in the embodiment of the present application includes a sound-producing portion 31, a balancing portion 32, and an ear clip portion 20. The ear clip portion 20 connects the sound-producing portion 31 and the balancing portion 32. The ear clip portion 20 has multiple usage postures, so the earphone 30 provided in the embodiment of the present application has multiple wearing states. The specific structure of the ear clip portion 20 can refer to the above description of the structure of the ear clip portion 20 provided in the embodiment of the present application.

[0182] In this embodiment of the present application, the sound-emitting portion 31 is connected to the first end portion 201, and the sound-emitting portion 32 is connected to the second end portion 202. This connection can be a rotational connection, so that the sound-emitting portion 31 and the balancing portion 32 can be rotated to adjust their angles relative to the ear 10 or the ear clip portion 20 in real time according to different wearing conditions. This not only achieves an ergonomically comfortable state, but also ensures that the earphone 30 is stably hung on the ear 10. Of course, in other embodiments, this rotational connection can be replaced with a fixed connection to meet the requirements of specific usage environments.

[0183] In the first wearing state of the earphone 30, please refer to Figures 21 and 23, the sound-emitting part 31 is located on the front side of the ear 10, and the balancing part 32 is located on the back side of the ear 10. The sound-emitting part 31 and the balancing part 32 clamp the ear 10 through the ear clip part 20, and the ear clip part 20 is in the first usage posture, as shown in Figure 19 or Figure 21.

[0184] In the second wearing state of the earphone 30 as shown in Figure 4, the ear clip part 20 switches from the first usage posture to the second usage posture, as shown in Figure 38 or Figure 40, and the sound-emitting part 31 changes its position under the drive of the ear clip part 20, thereby realizing different functional modes, such as changes in sound quality or volume.

[0185] The earphones 30 provided herein can be configured in a variety of wearing positions by providing an ear clip portion 20 with multiple usage postures, thereby enabling the wearing method to be adjusted according to the user's needs, effectively enhancing the user's experience. For example, the earphones 30 provided herein with multiple wearing positions can adapt to the different shapes and sizes of the user's ears, and the user can adjust the position of the ear clip portion 20 to change the usage posture at any time, providing the user with a higher quality and more extreme listening experience.

[0186] The following will specifically describe the position changes of the sound-emitting portion 31 and the balance portion 32 in the first wearing state and the second wearing state.

[0187] In the embodiment of the present application, the sound-emitting portion 31 is a sound-emitting device. The sound-emitting portion 31 is provided with a connecting surface 310 and a contact surface 311 (see FIG37 for markings). The connecting surface 310 is used to connect to the first end 201 of the ear clip portion 20. As shown in FIG21, in the first wearing state, the contact surface 311 abuts against the front side of the ear 10 and contacts the ear 10. For example, the contact surface 311 may be entirely or partially abutted against the cavum concha 152 of the ear 10, or may be abutted against the antihelix 13 of the ear 10 (see FIG19 for markings) or other areas on the front side of the ear 10. In this case, one surface of the balancing portion 32 also abuts against the back side of the ear 10. The sound-emitting portion 31 and the balancing portion 32 clamp the ear 10 through the clamping force provided by the ear clip portion 20, thereby providing a stable wearing state for the earphone 30.

[0188] When the user switches the ear clip portion 20 from the first usage posture to the second usage posture, the contact surface 311 moves toward the ear hole 16 of the ear 10, and the sound-emitting portion 31 covers at least a portion of the ear hole 16, as shown in Figure 22. At this point, the earphone 30 is in the second wearing state, wherein the balance portion 32 may remain located at the back of the ear 10 or move from the back of the ear 10 toward the edge near the helix 11. When the balance portion 32 is located at the back of the ear 10, the sound-emitting portion 31 and the balance portion 32 can still clamp the ear 10 using the clamping force provided by the ear clip portion 20. When the balance portion 32 moves to the edge of the helix 11, one surface of the balance portion 32 may still be in contact with the ear 10, thereby clamping the ear 10 together with the sound-emitting portion 31. Of course, when the balancing part 32 moves to the edge of the helix 11, due to the difference in the shape of the user's ear 10, the balancing part 32 may not form surface contact with the back side of the ear 10, but may be suspended at the edge of the helix 11 and form line contact with the ear 10, or may even be completely suspended in the air and have no contact with the edge of the ear 10. In this case, the earphone 30 is worn on the ear 10 mainly through the supporting force provided by the ear 10 to the sound-producing part 31, and in conjunction with the clamping force between the ear clip part 20 and the balancing part 32 and the sound-producing part 31.

[0189] Furthermore, as previously mentioned, the ear clip portion 20 provided in the embodiment of the present application has a first average radius of curvature near the first end 201 that is greater than the second average radius of curvature near the second end 202; that is, the curvature of the ear clip portion 20 near the second end 202 is significantly greater than the curvature near the first end 201. This configuration allows the balancing portion 32 connected to the second end 202 to provide greater clamping force for the earphone 30. During implementation, it should be noted that if the thickness of the balancing portion 32 is increased, the curvature near the second end 202 can be appropriately reduced. Conversely, if the thickness of the balancing portion 32 is reduced, the curvature near the second end 202 can be appropriately increased.

[0190] The earphones 30 provided in this embodiment also include a battery and a motherboard. The battery can be located in the sound-producing unit 31 or the balancing unit 32, and the motherboard can be located in the sound-producing unit 31 or the balancing unit 32. Of course, the earphones 30 can also include other structures, such as, but not limited to, a Bluetooth antenna module and a USB charging module, and are not limited to these in this embodiment.

[0191] In addition, in this embodiment, in addition to the connecting surface 310 and the contact surface 311, the sound-emitting portion 31 also has a sound-emitting surface 312, as shown in FIG37 . The connecting surface 310, the contact surface 311 and the sound-emitting surface 312 can be smoothly transitioned and connected, for example, by using a circular arc transition connection, thereby improving the wearing comfort of the earphone 30. In this embodiment, the area of ​​the sound-emitting surface 312 is smaller than the area of ​​the contact surface 311. The smaller sound-emitting surface 312 can easily extend to the ear hole 16 to form an in-ear shape, as shown in FIG22 . Even more, the smaller sound-emitting surface 312 may also form contact with the area near the ear hole 16, so that the ear 10 can further support the earphone 30. In addition, it should be noted that the embodiment of the present application does not limit the contact surface 311 and the sound-emitting surface 312 to two different surfaces. That is to say, the contact surface 311 and the sound output surface 312 provided in the embodiment of the present application can be two different surfaces, or two different areas on the same surface, or the same area on the same surface, as long as the contact surface 311 of the embodiment of the present application can be used to contact the ear and the sound output surface 312 can be used to produce sound.

[0192] The sound-emitting portion 31 provided in the embodiment of the present application is a sound-emitting device, which is provided with a sound outlet. The sound outlet hole is provided on the sound outlet surface 312 and can be aligned with the ear hole 16. In addition, the outer surfaces of the sound-emitting portion 31 and the balancing portion 32 provided in the embodiment of the present application can be made of an elastic material to increase the adhesion between the ear 10 and the ear, making it more comfortable and stable to wear.

[0193] The shapes and sizes of the sound-emitting part 31, the balancing part 32 and other components or structures shown in the drawings of this application are not intended to reflect their actual proportions, and their purpose is only to facilitate the explanation of the contents of the embodiments of this application.
