Description

[0001] This application is a divisional application. The application number of the original application is 202410425655.7, and the original application date is April 9, 2024. The entire contents of the original application are incorporated into this application by reference. Technical Field

[0002] The present application relates to the field of earphones, and in particular to an earphone and an audio device. Background Art

[0003] Clip-on wireless earphones can be clamped on the ears, which can reduce ear canal allergies and damage. Users can sense changes in the surrounding environment at any time, reduce the risk of accidents, and are suitable for long-term wear during sports, commuting, and daily work and life. Clip-on wireless earphones include a left earphone and a right earphone. The sound pickup holes of the left earphone and the right earphone need to face the side away from the bottom surface to ensure that the sound pickup effect of the sound pickup holes on the earphone is better. When wearing the earphones, users need to distinguish between the left earphone and the right earphone for wearing. Summary of the invention

[0004] The present application provides a headset and an audio device.

[0005] In a first aspect, the present application provides an earphone. The earphone comprises a first earphone body, a connecting arm and a second earphone body, wherein the connecting arm connects the first earphone body and the second earphone body. The second earphone body comprises an outer shell, wherein the outer shell is provided with a first sound pickup hole and a second sound pickup hole, wherein the first sound pickup hole and the second sound pickup hole are connected to the interior of the outer shell, and the first sound pickup hole and the second sound pickup hole are used to pick up external sound of the second earphone body. The center of the outer surface of the first earphone body, the center of the outer surface of the second earphone body and the center of the outer surface of the connecting arm are connected to form a symmetry plane, wherein the first sound pickup hole and the second sound pickup hole are spaced apart along a first direction, and the first direction is perpendicular to the symmetry plane. The first sound pickup hole and the second sound pickup hole are symmetrical about the symmetry plane.

[0006] It can be understood that when the user wears the earphone, the first earphone body can be clamped in the user's concha cavity, and the second earphone body is located outside the user's ear and on the side away from the first earphone body. The connecting arm is buckled on one side of the outer edge of the user's ear and extends from the concha cavity to the back of the ear. The connecting arm can clamp the user's auricle together with the first earphone body and the second earphone body, so that the earphone is worn on the ear. The center of the outer surface of the first earphone body, the center of the outer surface of the second earphone body, and the center of the outer surface of the connecting arm are connected to form a symmetry plane, and the symmetry plane can be roughly perpendicular to the user's ear.

[0007] Compared with the solution of only setting one sound pickup hole, the present application sets a first sound pickup hole and a second sound pickup hole at the same time. When one of the first sound pickup hole and the second sound pickup hole is blocked by sweat or dust, the other one can still work normally.

[0008] Compared with the technical solution of only setting one of the first sound pickup hole and the second sound pickup hole, in this application, the first sound pickup hole and the second sound pickup hole are arranged at intervals in the first direction, and the first direction is perpendicular to the symmetry plane. The first sound pickup hole and the second sound pickup hole are symmetrically arranged with respect to the symmetry plane. The first sound pickup hole and the second sound pickup hole can be located on both sides of the symmetry plane respectively. When the microphone in the second earphone picks up external sounds through the first sound pickup hole and the second sound pickup hole for active noise reduction or calls, no matter whether the user wears the earphone on the right ear or the left ear, one of the first sound pickup hole and the second sound pickup hole always faces the ground, and the other faces away from the ground. The interference effects received during the sound pickup process are the same, and do not change due to the change of spatial position. The sound pickup effects of the second earphone body are basically the same, and the sound output effects of the earphone are also basically the same. Moreover, when the user uses the earphone, no matter whether the user wears the earphone on the right ear or the left ear, the positions of the first sound pickup hole and the second sound pickup hole seen from the appearance are also the same. The user does not need to distinguish between the left and right ears when using the earphone.

[0009] In a possible implementation manner, the second earphone body includes a long axis, and the long axis is the connection line of the two farthest endpoints of the outer shell of the second earphone body in the first direction. The first sound pickup hole and the second sound pickup hole are located on the side of the long axis close to the connecting arm.

[0010] It can be understood that when the user wears the earphone, the long axis direction can be approximately perpendicular to the bottom surface direction. When sweat drips onto the outer shell of the second earphone during the process of the user wearing the earphone, compared with the scheme in which the first sound pickup hole and the second sound pickup hole are arranged on the long axis, by arranging the first sound pickup hole and the second sound pickup hole on the side of the long axis L1 close to the connecting arm, the sweat can slide down along the curve of the outer shell, which can reduce the risk of sweat directly dripping into the first sound pickup hole or the second sound pickup hole, and avoid the first sound pickup hole or the second sound pickup hole being blocked by sweat, affecting the sound pickup effect of the first sound pickup hole or the second sound pickup hole.

[0011] When the user wears the earphone, the second earphone body is located on the side of the user's ear outside and away from the first earphone body. The connecting arm is buckled on the outer edge side of the user's ear and extends from the concha to the back of the ear. By arranging the first sound pickup hole and the second sound pickup hole on the side of the long axis close to the connecting arm, compared with the scheme in which the first sound pickup hole and the second sound pickup hole are arranged on the side of the long axis away from the connecting arm, the first sound pickup hole and the second sound pickup hole are farther from the user's skin, and there is less blockage around this position. When the microphone in the second earphone body picks up sound through the first sound pickup hole and the second sound pickup hole, there is less external blockage.

[0012] In a possible implementation manner, the outer shell of the second earphone body is provided with a first connection hole, and the first connection hole and the first sound pickup hole are arranged at intervals. The first connection hole is used for the end of the connecting arm to extend into the second earphone body.

[0013] In the first direction, the projection of the center of the first sound pickup hole on the symmetry plane is the first projection, and the projection of the center of the first connection hole on the symmetry plane is the second projection. The distance between the first projection and the second projection is A1, and the distance between the second projection and the center of the outer surface of the second ear body is A2.

[0014] The relationship between A1 and A2 satisfies:

[0015] It can be understood that when the user wears the earphone, the second ear body is located on the side outside the user's ear and away from the first ear body. The connecting arm 300 is buckled on the outer edge side of the user's ear and extends from the concha cavity to the back of the ear. The distance from the position of the first sound pickup hole to the connecting arm is less than the distance from the first sound pickup hole to the user's skin hair. There is less blockage around the position of the first sound pickup hole. When the microphone in the second earphone body picks up sound through the first sound pickup hole, there is less external blockage.

[0016] In a possible implementation manner, the second ear body includes a first feedforward microphone and a second feedforward microphone. The first feedforward microphone and the second feedforward microphone are arranged inside the housing. The first feedforward microphone picks up the external sound of the second ear body through the first sound pickup hole, and the second feedforward microphone picks up the external sound of the second ear body through the second sound pickup hole. The first feedforward microphone and the second feedforward microphone are symmetric about the symmetry plane.

[0017] It can be understood that the first feedforward microphone and the second feedforward microphone can be used for active noise cancellation of the earphone. Active noise cancellation is a method of identifying an unwanted sound source as noise, and eliminating the original noise by generating an "anti-noise" signal, so as to eliminate the noise in real time. When the user uses the earphone, the noise in the sound emitted by the earphone is small, and the user experience is better. The first feedforward microphone and the second feedforward microphone are symmetrically arranged about the symmetry plane. Whether the user wears the earphone on the right ear or the left ear, the noise information received when the first feedforward microphone and the second feedforward microphone pick up noise is not much different, and the active noise cancellation effect of the earphone is basically the same. In this way, when the user uses the earphone, whether the user wears the earphone on the right ear or the left ear, the sound output effect of the earphone is basically the same.

[0018] In a possible implementation manner, the second ear body is provided with a first duct. The first duct is located inside the housing. The first duct communicates with the first sound pickup hole, and the sound pickup surface of the first feedforward microphone is arranged opposite to the first duct. The first duct is curved.

[0019] It can be understood that when the airflow near the first sound pickup hole passes through the first duct, the curved duct can buffer the airflow, and the wind noise is small when the first feedforward microphone picks up sound through the first duct.

[0020] In a possible implementation manner, the second ear body includes a first bracket, the first bracket is fixed inside the housing of the second ear body, the first feedforward microphone is fixed on the first bracket, and the first duct is located on the first bracket.

[0021] It can be understood that, compared with the solution where the first duct is directly provided on the housing of the second ear body, setting the first duct on the first bracket is beneficial to reducing the molding difficulty of the housing of the second ear body and is beneficial to the replacement and maintenance of the internal components of the second ear body. The first bracket can be used to carry the first feedforward microphone. The first feedforward microphone can be assembled to the first bracket first, and then assembled into the housing of the second ear body as a whole, which is beneficial to the assembly of the second ear body.

[0022] In a possible implementation manner, the first ear body includes a housing and a first capacitive sensor, the first capacitive sensor is arranged inside the housing of the first ear body, the second ear body includes a second capacitive sensor and a controller, both the second capacitive sensor and the controller are arranged inside the housing of the second ear body, and the first capacitive sensor and the second capacitive sensor are electrically connected to the controller. The first capacitive sensor is used to obtain a first capacitance value in a first environment, the second capacitive sensor is used to obtain a second capacitance value in a second environment, and the controller is used to judge whether the user wears the earphone according to the first capacitance value and the second capacitance value.

[0023] It can be understood that, compared with the solution of only setting the first capacitive sensor or the second capacitive sensor, in this application, the first capacitive sensor is set on the first ear body, and the second capacitive sensor is set on the second ear body. The controller can judge the state of the earphone according to the absolute value and relative value of the capacitance generated by the first capacitive sensor and the second capacitive sensor, which can reduce the risk of accidental touch and improve the accuracy of earphone wearing detection.

[0024] In a possible implementation manner, the outer surface of the first earphone is symmetric about a symmetry plane;

[0025] The outer surface of the second earphone is symmetric about a symmetry plane;

[0026] The outer surface of the connecting arm is symmetric about a symmetry plane.

[0027] It can be understood that the outer surfaces of the first ear body, the flexible connecting arm and the second ear body are completely symmetric about the symmetry plane. Therefore, after the originally set left ear earphone is flipped, it can be worn on the right ear. Therefore, when the user wears the earphone provided in this application, there is no need to distinguish between the left and right ears in terms of appearance.

[0028] In a possible implementation manner, the second ear body further includes an antenna module, and the antenna module includes a main unit and a parasitic unit. The main unit and the parasitic unit are disposed inside the housing of the second ear body. The outer surface of the housing of the second earphone is symmetric about a symmetry plane, and the main unit and the parasitic unit are symmetric about the symmetry plane.

[0029] It can be understood that when the user wears the earphone on the left ear, during the operation of the antenna module, when the main unit of the antenna structure is close to the user's skin, it is more blocked and the signal is easily interfered. The parasitic unit is located at a position farther from the user and is less blocked, so the signal is not easily interfered. When the user wears the earphone on the right ear, the parasitic unit is close to the user's skin, and the main unit is located at a position farther from the user. In this way, no matter whether the user wears the earphone on the left ear or the right ear, the interference to the signal of the antenna module is about the same, and the sensitivity of the earphone to play sound or receive signals is also relatively similar, providing a better user experience.

[0030] In a possible implementation manner, the second ear body includes a battery, a first electrode, and a second electrode. The first electrode and the second electrode are both embedded in the housing of the second ear body. The first electrode and the second electrode are both electrically connected to the battery. The first electrode, the second electrode, the first sound pickup hole, and the second sound pickup hole are spaced apart from each other. The outer surface of the housing of the second earphone is symmetric about a symmetry plane. One end of the first electrode and one end of the second electrode are exposed relative to the outer surface of the housing of the second ear body, and the first electrode and the second electrode are symmetric about the symmetry plane.

[0031] It can be understood that one end of the first electrode and one end of the second electrode are exposed relative to the outer surface of the housing of the second ear body, and the first electrode and the second electrode are symmetric about the symmetry plane. No matter whether the user wears the earphone on the left ear or the right ear, the appearances of the first electrode and the second electrode on the housing of the second ear body are the same, providing a better user experience when the user wears the earphone.

[0032] In a possible implementation manner, the first ear body includes a housing and a speaker. The speaker is fixedly connected to the inner surface of the housing of the first ear body. The speaker and the inner surface of the housing of the first ear body enclose a first sub-cavity, and the speaker and the inner surface of the housing of the first ear body enclose a second sub-cavity. The sound-emitting surface of the speaker faces the first sub-cavity. The outer surface of the first ear body is symmetric about a symmetry plane. The housing of the first ear body is provided with two pressure relief holes, and the pressure relief holes communicate the second sub-cavity with the outside of the first ear body. The two pressure relief holes are spaced apart and symmetric about the symmetry plane.

[0033] It can be understood that, compared with the method of only setting one pressure relief hole, no matter whether the user wears the earphone on the left ear or the right ear, the two pressure relief holes are symmetric about the symmetry plane, and one of the two pressure relief holes always faces the ground and the other faces away from the ground to ensure the pressure relief effect. The user does not need to distinguish between the left and right ears when wearing the earphone. In addition, when one of the pressure relief holes is blocked by sweat, there is another pressure relief hole that can work to balance the air pressure in the second sub-chamber.

[0034] In a possible implementation manner, the first ear body includes a housing and a bone sensor, and the bone sensor is disposed inside the housing of the first ear body.

[0035] It can be understood that the bone vibration sensor can be used to pick up the vibrations when the user is speaking, which is beneficial to call noise reduction.

[0036] In a possible implementation manner, along the length direction of the connecting arm, the connecting arm has a first end portion and a second end portion arranged at intervals. The first end portion is connected to the first ear body, and the second end portion is connected to the second ear body. The central axis directions of the first end portion and the second end portion are arranged at an included angle, and the range of the included angle is within the range of 11.4° to 26°.

[0037] It can be understood that, compared with the scheme in which the central axis directions of the first end portion and the second end portion of the connecting arm 300 are arranged in parallel, when the first end portion and the second end portion of the connecting arm are arranged at an included angle within the range of 11.4° to 26°, when the user wears the earphone 0, the relative positions of the first ear body and the second ear body can fit the ear inclination and contour curve of the user more closely, effectively reducing the pressure feeling of the first ear body and the second ear body of the earphone 0 on the earphone, and the user experience is better.

[0038] In a possible implementation manner, the connecting arm includes a tube body and a wire harness. The tube body is provided with a first channel, and the first channel is arranged along the length direction of the tube body. The openings of the first channel are respectively located on the first end face and the second end face of the tube body. The wire harness is located inside the first channel. One end of the wire harness is exposed at the first end face of the tube body for electrically connecting the first ear body, and the other end of the wire harness is exposed at the second end face of the tube body for electrically connecting the second ear body. There is a gap between the wire harness and the wall surface of the first channel.

[0039] It can be understood that when the connecting arm is bent, the deformation degree of the wire harness can be smaller than that of the tube body. In other words, when the connecting arm is bent, the stretching amount of the wire harness is smaller than that of the tube body. In this way, the wire harness is not easily broken and has a longer service life.

[0040] In a possible implementation, the wire harness includes a first signal line, a second signal line, a first encapsulation member, and a second encapsulation member. The first signal line is a current transmission channel for the power supply. The second signal line is a signal transmission channel for the speaker. The second encapsulation member is provided with a second installation channel in the length direction. The second signal line is assembled in the second installation channel. The second encapsulation member and the second signal line form a sub-wire harness. The first encapsulation member is provided with a first installation channel in the length direction. The sub-wire harness and the first signal line are jointly assembled in the second installation channel.

[0041] It can be understood that the signal of the speaker is easily affected by other signals and has high requirements for crosstalk. The second signal line is separately assembled and encapsulated by the second encapsulation member 343 to form a sub-wire harness. Then, it is assembled and encapsulated by the first encapsulation member together with the first signal line. The signal of the speaker is not easily interfered by the lines of other signals, and the sound effect of the earphone is better.

[0042] In a possible implementation, the length of the outer shell of the second ear body in the second direction is less than the length in the first direction. The second direction is the direction from the end where the connecting arm connects to the second ear body (i.e., the second end) to the center of the outer surface of the second ear body. The length of the outer shell of the second ear body in the third direction is less than the length in the first direction. The third direction is perpendicular to the first direction and perpendicular to the second direction.

[0043] It can be understood that the outer shell of the second ear body is generally ellipsoidal. When the user wears the earphone, the first direction is generally the same as the length direction of the ear. Compared with the technical solution where the first direction is perpendicular to the length direction of the ear, in this solution, when the user wears the earphone, the second ear body fits more closely to the arc surface of the user's auricle, which can improve the wearing comfort of the user.

[0044] In a possible implementation, there is a third gap S1 between the connecting arm and the first ear body. There is a fourth gap S2 between the connecting arm and the second ear body. The third gap S1 can be greater than the fourth gap S2.

[0045] It can be understood that during the assembly process of the connecting arm, the first ear body, and the second ear body, due to assembly tolerances, when the included angle between the central axis direction of the first end of the tube body and the central axis direction of the second end of the tube body fails to reach the preset ideal angle, at this time, fine adjustment can be performed through the third gap S1 between the first connecting member and the first ear body to adjust the relative positions of the first ear body and the second ear body.

[0046] In a second aspect, the present application provides an audio device. The audio device includes an earphone case and an earphone. The earphone is disposed in the earphone case. Description of the Drawings

[0093] The embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

[0094] In the description of the embodiments of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Among them, "fixed connection" means that the components are connected to each other and the relative positional relationship after connection remains unchanged. It should be understood that when component A is fixedly connected to component C through component B, relative positional relationship changes due to the deformation of component A, component B, and component C itself are allowed. Among them, when two components are integrally formed into an integrated structure, it means that during the process of forming one of the two components, the component is connected to the other component together, and there is no need to connect the two components together by means of reprocessing (such as bonding, welding, snap connection, screw connection).

[0095] In the embodiments of the present application, the orientation terms mentioned, such as "upper", "lower", "side", etc., are only with reference to the direction of the attached drawings. Therefore, the orientation terms used are for better and clearer illustration and understanding of the embodiments of the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the embodiments of the present application.

[0096] The term "plurality" means at least two. The term "above" includes the base number. The term "and / or" is an association relationship describing associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. The terms "first", "second", etc. are used only for descriptive purposes and cannot be construed as implying or suggesting relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first", "second" may explicitly or implicitly include one or more of such features.

[0097] The present application provides an earphone 1000 and a pair of earphones. The earphone 1000 is a clip-on wireless earphone (True Wireless Stereo, TWS) and can be clipped on the ear. The clip-on earphone can reduce the discomfort of the wearer's ear and improve the wearing comfort. A pair of earphones includes two earphones 1000, which can be divided into a first earphone and a second earphone. The first earphone and the second earphone are respectively used for wearing on the left ear and the right ear of the user. Among them, the first earphone and the second earphone are not distinguished by left and right ears, that is, the first earphone can be worn on the left ear or the right ear, and the second earphone can be worn on the left ear or the right ear; thus improving the usage portability of the earphone 1000.

[0098] In some embodiments, the earphone 1000 can be an open earphone. In this way, the earphone does not need to go deep into the inner part of the user's ear canal, which can reduce ear canal allergies and injuries. The user can perceive the changes in the surrounding environment at any time and reduce the risk of accidents.

[0099] Figure 1 It is a schematic structural diagram of an embodiment of the earphone 1000 provided by the present application. Figure 2 is Figure 1 An exploded schematic diagram of an embodiment of the earphone 1000 shown in

[0100] Such as Figure 1 and Figure 2As shown, the earphone 1000 is generally U-shaped, including a first ear body 100, a second ear body 200, and a connecting arm 300. The connecting arm 300 is generally U-shaped and is connected between the first ear body 100 and the second ear body 200. The first ear body 100 is electrically connected to the second ear body 200. Exemplarily, along the length direction of the connecting arm 300, the connecting arm 300 has a first end portion and a second end portion arranged opposite to each other. The first end portion is connected to the first ear body 100, and the second end portion is connected to the second ear body 200. In this way, the first ear body 100 and the second ear body 200 can form a physical connection through the connecting arm 300. In addition, the first ear body 100 and the second ear body 200 can also be electrically connected through the connecting arm 300. For example, the connecting arm 300 can include a wire harness. One end of the wire harness is electrically connected to the first ear body 100, and the other end of the wire harness can be electrically connected to the second ear body 200.

[0101] For convenience of description, the geometric centers of the outer surfaces of the first ear body 100, the second ear body 200, and the connecting arm 300 determine a unique plane, which is the O-O plane ( Figure 1 schematically shown by a dashed line in the figure). For ease of description, the direction perpendicular to the O-O plane is defined as the Z-axis, the direction in which the end of the connecting arm 300 connected to the second ear body 200 points to the center of the second ear body 200 is defined as the X-axis direction, and the direction perpendicular to both the X-axis and the Z-axis is defined as the Y-axis.

[0102] In some embodiments, the outer surface of the first ear body 100 can be symmetric about a symmetry plane, the outer surface of the second ear body 200 can be symmetric about a symmetry plane, and the outer surface of the connecting arm 300 can be symmetric about a symmetry plane. In this way, the earphone 1000 as a whole is symmetric about the symmetry plane.

[0103] Figure 3 It is a state diagram of an embodiment in which a user uses the earphone 1000 provided in the present application.

[0104] As Figure 3 shown, the first ear body 100 can be used for sound generation. When the user uses the earphone, the first ear body 100 can be held in the user's concha cavity without going deep into the user's ear canal, that is, the earphone 1000 of the present application is an open earphone. The tolerance of the human concha cavity is much higher than that of the ear canal. Therefore, the earphone 1000 provided in the present application can greatly improve the wearing comfort compared with in-ear audio devices.

[0105] The second ear body 200 is located outside the user's ear and on the side facing away from the first ear body 100. The connecting arm 300 is buckled on the outer edge side of the user's ear and extends from the concha to the rear position of the ear. It can be understood that the connecting arm 300, together with the first ear body 100 and the second ear body 200, clamps the user's auricle, and then wears the earphone 1000 on the ear.

[0106] In some embodiments, the connecting arm 300 can have a deformable ability and can be used to adjust the distance between the first ear body 100 and the second ear body 200, so that the distance between the first ear body 100 and the second ear body 200 is adjusted from the initial distance to the adjusted distance. Among them, the initial distance refers to the distance between the first ear body 100 and the second ear body 200 when the earphone 1000 is not worn on the user's ear. The adjusted distance refers to the distance after the initial distance becomes larger or smaller. It should be noted that both the initial distance and the adjusted distance refer to the distance between the first ear body 100 and the second ear body 200; the distance between the surfaces of the first ear body 100 and the second ear body 200 facing each other, that is, the distance between the two surfaces of the earphone 1000 that first contact the ear.

[0107] It can be understood that the earphone 1000 equipped with the deformable connecting arm 300 can be adapted to users with different ear thicknesses, provide appropriate clamping force for each user, and avoid the influence of too tight or too loose clamping on the wearing experience. At the same time, when the user puts on and takes off the earphone 1000 provided in this application, the user can use the connecting arm 300 to increase the distance between the first ear body 100 and the second ear body 200 to ensure the smooth wearing and taking off of the earphone 1000, avoid deforming the ear under pressure, and improve the user experience when wearing and taking off the earphone 1000.

[0108] When the user uses the earphone, the first ear body 100 can be used for sound production. For example, the first ear body 100 can include a speaker, and sound is produced through the speaker. The first ear body 100 can be clamped in the user's concha, and the second ear body 200 is located outside the user's ear and on the side facing away from the first ear body 100. The second ear body 200 can be used to pick up the external noise of the second ear body 200 and is used in the active noise cancellation (ANC) design system of the earphone 1000. Active noise cancellation is a method of identifying an unwanted sound source as noise and eliminating the original noise by generating an "anti-noise" signal, so as to eliminate the noise in real time. When the user uses the earphone 1000, the noise in the sound emitted by the earphone 1000 is smaller, and the user experience is better. A specific embodiment of the second ear body 200 will be introduced in detail below with reference to the drawings.

[0109] In some embodiments, the outer surface of the first ear body 100 is symmetric about the first symmetry plane. The outer surface of the second ear body 200 is symmetric about the second symmetry plane. The outer surface of the connecting arm 300 is symmetric about the third symmetry plane. The first symmetry plane, the second symmetry plane, and the third symmetry plane are coplanar. Exemplarily, any one of the first symmetry plane, the second symmetry plane, and the third symmetry plane can be coplanar with the symmetry plane (i.e., the 0-0 plane). In this way, the overall appearance of the earphone 1000 is a symmetric structure, and during the user's use of the earphone 1000, there is no need to distinguish between the left and right ears.

[0110] In other embodiments, due to assembly tolerances, there can also be an angle between any two of the first symmetry plane, the second symmetry plane, and the third symmetry plane, and the angle is less than or equal to 1°. For example, the angle between any two of the first symmetry plane, the second symmetry plane, and the third symmetry plane can be 0.2°, 0.5°, 0.9°, or 1°, etc. Exemplarily, the angle between the first symmetry plane and the second symmetry plane can be less than 1°, or the angle between the first symmetry plane and the third symmetry plane can be less than 1°, or the angle between the second symmetry plane and the third symmetry plane can be less than 1°.

[0111] Figure 4 is Figure 2 A schematic structural view of the second ear body 200 shown in another angle.

[0112] As Figure 2 and Figure 4 shown, the length D1 of the housing 209 of the second ear body in the first direction is greater than the length D2 in the second direction. The second direction is the direction from the end where the connecting arm 300 is connected to the second ear body 200 (i.e., the second end) to the center of the outer surface of the second ear body 200. The second direction is different from the first direction. Attached Figure 4 schematically shows that the first direction is the Z-axis direction. The second direction is the X-axis direction. In other embodiments, the first direction can also be any direction in the X-Z plane, for example, a direction at a certain angle to the Z-axis. The second direction can also be any direction in the X-Z plane, for example, a direction at a certain angle to the X-axis.

[0113] Exemplarily, the second ear body 200 includes a major axis L1. The major axis L1 is the line connecting the two farthest endpoints of the housing 209 of the second ear body 200 in the first direction. The housing 209 of the second ear body 200 can have many lines in the first direction, and the major axis L1 is the longest one among them. The length of the major axis L1 is D1.

[0114] In some embodiments, the second symmetry plane is perpendicular to the first direction (i.e., the Z-axis direction). At this time, the second symmetry plane is the X-Y plane.

[0115] In some embodiments, the second ear body 200 may include a short axis L2. The short axis L2 is the length between the two farthest endpoints of the second ear body 200 in the second direction. The outer shell 209 of the second ear body 200 may have a plurality of connecting lines in the second direction, and the short axis L2 is the longest one among them.

[0116] Exemplarily, the length D2 of the short axis L2 is in the range of 11.44 millimetres (mm) to 13.44 mm. For example, the length D of the short axis L2 may be 11.44 mm, 12.44 mm, or 13.44 mm.

[0117] In some embodiments, the length of the outer shell 209 of the second ear body 200 in the second direction is less than the length in the first direction. The length of the outer shell 209 of the second ear body 200 in the third direction is less than the length in the first direction, and the third direction and the second direction are different from the first direction. Attached Figure 2 shows that the third direction is the Y-axis direction. In other embodiments, the third direction may also be any direction in the X-Y plane, for example, a direction at a certain angle to the Y-axis. In this way, the second ear body 200 may be generally ellipsoidal, and when the user wears the earphone 1000, the longer direction of the ellipsoid is generally the same as the length direction of the ear.

[0118] In some embodiments, the shape of the outer shell 209 of the second ear body 200 may be "broad bean" shaped. It can be understood that the second ear body 200 adopts a profiling design and is in the shape of a broad bean, which fits the arc surface of the user's auricle when worn, and can improve the wearing comfort of the user. When the user wears the earphone 1000, the first direction is generally the same as the length direction of the ear.

[0119] Figure 5 is Figure 4 an exploded schematic view of an embodiment of the second ear body 200 shown in Figure 6 is Figure 4 a partial sectional view of an embodiment of the second ear body 200 shown in

[0120] As Figure 5 and Figure 6As shown, the second ear body 200 may include a housing 209, an antenna module 230, a battery 240, a main board bracket 250, a main board 260, a first bracket 271, a second bracket 272, a first feedforward microphone 273, a second feedforward microphone 274, a second circuit board 280, a second capacitive sensor 290, and a charging terminal 291. Among them, the antenna module 230, the battery 240, the main board bracket 250, the main board 260, the first bracket 271, the second bracket 272, the first feedforward microphone 273, the second feedforward microphone 274, the second circuit board 280, and the second capacitive sensor 290 may all be disposed inside the housing 209 of the second ear body 200.

[0121] Exemplarily, the housing 209 of the second ear body 200 may include a third housing 210 and a fourth housing 220. The third housing 210 is connected to the fourth housing 220 to enclose a second space 201. The antenna module 230, the battery 240, the main board bracket 250, the main board 260, the first bracket 271, the second bracket 272, the first feedforward microphone 273, the second feedforward microphone 274, the second circuit board 280, and the second capacitive sensor 290 may all be disposed within the second space 201.

[0122] As Figure 6 shown, the third housing 210 may have an outer surface 211, an inner surface 212, and a third end face 213. Among them, the outer surface 211 and the inner surface 212 are disposed opposite to each other, and the inner surface 212 faces the second space 201. The third end face 213 is connected between the outer surface 211 and the inner surface 212. The fourth housing 220 may have an outer surface 221, an inner surface 222, and a fourth end face 223. Among them, the outer surface 221 and the inner surface 222 are disposed opposite to each other, and the inner surface 222 faces the second space 201. The fourth end face 223 is connected between the outer surface 221 and the inner surface 222.

[0123] When the third housing 210 is connected to the fourth housing 220, the third end face 213 of the third housing 210 is connected to the fourth end face 223 of the fourth housing 220. The outer surface 211 of the third housing 210 and the outer surface 221 of the fourth housing 220 constitute the outer surface of the second ear body 200. The inner surface 212 of the third housing 210 and the inner surface 222 of the fourth housing 220 constitute the inner surface of the second ear body 200. The inner surface 212 of the third housing 210 and the inner surface 222 of the fourth housing 220 enclose the second space 201.

[0124] In some embodiments, the third housing 210 may be symmetric about a second symmetry plane. The fourth housing 220 may also be symmetric about the second symmetry plane. Thus, the outer surface of the second ear body 200 formed by the outer surface 211 of the third housing 210 and the outer surface 221 of the fourth housing 220 may also be symmetric about the second symmetry plane.

[0125] Figure 7 is Figure 5 A schematic structural diagram of an embodiment of the third housing 210 shown in

[0126] As Figure 7 shown, the third housing 210 is provided with a first sound pickup hole 214 and a second sound pickup hole 215 which are spaced apart. The first sound pickup hole 214 communicates with the outer surface 211 and the inner surface 212 of the third housing 210. The second sound pickup hole 215 may communicate with the outer surface 211 and the inner surface 212 of the third housing 210.

[0127] In some embodiments, the first sound pickup hole 214 and the second sound pickup hole 215 may be arranged at intervals in the first direction. In some embodiments, the first sound pickup hole 214 and the second sound pickup hole 215 may be symmetric about the second symmetry plane.

[0128] The third housing 210 is provided with a first charging hole 216 and a second charging hole 217 which are spaced apart. The first charging hole 216, the second charging hole 217, the first sound pickup hole 214, and the second sound pickup hole 215 are spaced apart from each other. The first charging hole 216 may communicate with the outer surface 211 and the inner surface 212 of the third housing 210. The second charging hole 217 may communicate with the outer surface 211 and the inner surface 212 of the third housing 210.

[0129] In some embodiments, the first charging hole 216 and the second charging hole 217 may be arranged at intervals in the first direction.

[0130] In some embodiments, the first charging hole 216 and the second charging hole 217 may be symmetric about the symmetry plane (i.e., the 0-0 plane).

[0131] The third housing 210 may further be provided with a first connection hole 218. The first connection hole 218 is spaced apart from the first sound pickup hole 214, the second sound pickup hole 215, the first charging hole 216, and the second charging hole 217. The first connection hole 218 communicates with the outer surface 211 and the inner surface 212 of the third housing 210.

[0132] In some embodiments, the first sound pickup hole 214 and the second sound pickup hole 215 may be arranged at intervals in the first direction and are located on both sides of the first connection hole 218. Figure 8 is Figure 5 A schematic assembly diagram of an embodiment of the antenna module 230 and the third housing 210 shown in

[0133] As Figure 8As shown, the antenna module 230 can be fixedly connected to the inner surface 212 of the third housing 210. Exemplarily, the antenna module 230 can be fixedly connected to the inner surface 212 of the third housing 210 by means of gluing, welding, etc.

[0134] In some embodiments, the inner surface 212 of the third housing 210 can be provided with a first positioning post 2121. The first positioning post 2121 can be formed by protruding from the inner surface 212. At the same time, the antenna module 230 can be correspondingly provided with a positioning hole 233. When the antenna module 230 is installed on the third housing 210, at least a part of the first positioning post 2121 is located in the positioning hole 233. It can be understood that by providing the first positioning post 2121 and the positioning hole 233, during the assembly process of the antenna module 230, it can help with quick positioning, and at the same time, in subsequent assembly processes, it can also prevent the antenna module 230 from shifting.

[0135] In some embodiments, the antenna module 230 can be symmetric about the symmetry plane O - O.

[0136] Figure 9 Yes Figure 8 is an exploded schematic view of an embodiment of the antenna module 230 shown in

[0137] As Figure 9 shown, the antenna module 230 can include a packaging structure 231 and an antenna structure 232. The antenna structure 232 is embedded in the packaging structure 231. The packaging structure 231 is used for the protection and insulation of the antenna structure 232. The antenna structure 232 can be used for transmitting and receiving antenna signals.

[0138] In some embodiments, the antenna structure 232 can be symmetric about the symmetry plane O - O. In this way, no matter whether the user wears the earphone 1000 on the left ear or the right ear, the interference received by the signal of the antenna module 230 is relatively small, and the sensitivity of the earphone 1000 to play sound or receive signals is also relatively similar, providing a better user experience.

[0139] In some embodiments, the antenna module 230 may employ a monopole antenna with parasitic elements. Exemplarily, the antenna structure 232 includes a main body unit 2311, a parasitic unit 2312, a ground trace 2313, and a feeding trace 2314. The main body unit 2311 and the parasitic unit 2312 are spaced apart and insulated. One end of the feeding trace 2314 is connected to the main body unit 2311, and the other end is connected to the main board 250 (not shown in the figure). The feeding trace 2314 is used to supply power to the main body unit 2311. One end of the ground trace 2313 is connected to the parasitic unit 2312, and the other end is connected to the main board 250 (not shown in the figure). The ground trace 2313 is used to ground the parasitic unit 2312. Among them, the main body unit 2311 is a monopole antenna. The parasitic unit 2312 serves as a parasitic element. During the operation of the antenna module 230, through the feeding trace 2314, the main board 250 (not shown in the figure) can supply power to the main body unit 2311 to activate the main body unit 2311 to work. After the main body unit 2311 is powered on, it capacitively couples and excites the parasitic unit 2312, and a capacitive coupling excitation parasitic mode can be formed between the main body unit 2311 and the parasitic unit 2312, so that the parasitic unit 2312 can also have the function of the antenna module 230.

[0140] In some embodiments, the main body unit 2311 and the parasitic unit 2312 may be symmetric with respect to the symmetry plane 0-0. It can be understood that during the operation of the antenna module 230, when the main body unit 2311 of the antenna structure 232 is close to the user's skin, it is more blocked and the signal is easily interfered. The parasitic unit 2312 is located at a position farther from the user and is less blocked, and the signal is not easily interfered. Vice versa, when the parasitic unit 2312 is close to the user's skin, the main body unit 2311 is located at a position farther from the user. In this way, no matter whether the user wears the earphone 1000 on the left ear or the right ear, the interference to the signal of the antenna module 230 is about the same, and the sensitivity of the earphone 1000 to play sound or receive signals is also relatively similar, providing a better user experience.

[0141] In some embodiments, along the Z-axis direction, the distance between the main body unit 2311 and the parasitic unit 2312 may be 0.5 mm.

[0142] In some embodiments, along the Z-axis direction, the length L of the antenna module 230 may be 13.8 mm. Along the X-axis direction, the width W of the antenna module 230 may be 5.9 mm.

[0143] In some embodiments, the antenna module 230 may employ a flexible printed circuit (FPC) antenna. It can be understood that compared with other forms of the antenna module 230, the FPC antenna has a smaller volume and is flexible, with a higher flexibility during laying.

[0144] Figure 10 is Figure 5 A schematic diagram of the partial structural assembly of the second ear body 200 shown in Figure 11 is Figure 10 A sectional view of an embodiment of the structure shown in the cross-section line B-B.

[0145] As Figure 10 and Figure 11 shown, the battery 240 can be disposed on a side of the antenna module 230 away from the third housing 210. The battery 240 can be fixedly connected to the inner surface 212 of the third housing 210. Exemplarily, the battery 240 can be fixedly connected to the inner surface 212 of the third housing 210 by an adhesive means.

[0146] In some embodiments, along the Y-axis direction, the battery 240 and the antenna module 230 are opposite and spaced apart. Exemplarily, along the Y-axis direction, the distance between the battery 240 and the antenna module 230 can be greater than or equal to 0.2 mm. For example, the distance between the battery 240 and the antenna module 230 can be greater than or equal to 0.23 mm.

[0147] Along the first direction (i.e., the Z-axis direction), the first bracket 271 and the second bracket 272 are spaced apart on both sides of the battery 240. The first bracket 271 and the second bracket 272 are spaced apart from the antenna module 230. Exemplarily, the first bracket 271 and the second bracket 272 can be fixedly connected to the third housing 210. For example, the first bracket 271 and the second bracket 272 can be fixedly connected to the third housing 210 by an adhesive means. The first feedforward microphone 273 is fixedly connected to the first bracket 271. The first feedforward microphone 273 is spaced apart from the battery 240 and the antenna module 230. The second feedforward microphone 274 is fixedly connected to the second bracket 272. The first feedforward microphone 273 is spaced apart from the battery 240 and the antenna module 230. The first bracket 271 can be used to carry the first feedforward microphone 273. The second bracket 272 can be used to carry the second feedforward microphone 274. The first feedforward microphone 273 and the second feedforward microphone 274 are used for active noise cancellation, pick up the ambient sound (i.e., the external ear noise) near the second ear body 200, and output an inverted sound to cancel the ambient sound. Exemplarily, the first feedforward microphone 273 can be fixedly connected to a side of the first bracket 271 away from the battery 240. The second feedforward microphone 274 can be fixedly connected to a side of the second bracket 272 away from the battery 240. At this time, the first feedforward microphone 273 and the second feedforward microphone 274 are spaced apart in the Z-axis direction.

[0148] In some embodiments, the first bracket 271 and the second bracket 272 can be symmetric about the 0-0 plane.

[0149] In some embodiments, the first feedforward microphone 273 and the second feedforward microphone 274 may be symmetric about the 0-0 plane.

[0150] Figure 12 Is Figure 5 An assembly schematic diagram of an embodiment of the first feedforward microphone 273, the second feedforward microphone 274, the first bracket 271, the second bracket 272 and the second circuit board 280 shown in Figure 13 Is Figure 12 A partial cross-sectional view of an embodiment of the structure shown in at the cross-section line C-C.

[0151] As Figure 12 And Figure 13 As shown in and , the first feedforward microphone 273 and the second feedforward microphone 274 are connected to the second circuit board 280 and electrically connected to the second circuit board 280. The first bracket 271 and the second bracket 272 are connected to the second circuit board 280. Exemplarily, the second circuit board 280 is disposed between the first feedforward microphone 273 and the first bracket 271. The first bracket 271 can also be used to carry this part of the second circuit board 280 connected between the first feedforward microphone 273 and the first bracket 271. The second circuit board 280 is disposed between the second feedforward microphone 274 and the second bracket 272. The second bracket 272 can also be used to carry this part of the second circuit board 280 connected between the second feedforward microphone 274 and the second bracket 272.

[0152] Figure 14 Is Figure 10 A partial cross-sectional view of an embodiment of the structure shown in at the cross-section line D-D.

[0153] As Figure 14 As shown in , the second ear body 200 may be provided with a first duct 2711. The first duct 2711 is located inside the housing of the second ear body 200. The first duct 2711 communicates with the first sound pickup hole 214. The sound pickup surface of the first feedforward microphone 273 is disposed opposite to the first duct 2711. The second ear body 200 may be provided with a second duct 2721. The second duct 2721 is located inside the housing 209 of the second ear body 200. The second duct 2721 communicates with the second sound pickup hole 215. The sound pickup surface of the second feedforward microphone 274 is disposed opposite to the second duct 2721.

[0154] Exemplarily, the first bracket 271 may be provided with a first duct 2711. One end of the first duct 2711 is disposed opposite to and communicated with the first sound pickup hole 214. The other end of the first duct 2711 is disposed opposite to the sound pickup surface of the first feedforward microphone 273. In this way, the external noise of the second ear body 200 near the first sound pickup hole 214 can pass through the first sound pickup hole 214 and the first duct 2711 and reach near the sound pickup surface of the first feedforward microphone 273, and is picked up by the first feedforward microphone 273. The second bracket 272 may also be provided with a second duct 2721. One end of the second duct 2721 may be disposed opposite to and communicated with the second sound pickup hole 215. The other end of the second duct 2721 may be disposed opposite to the sound pickup surface of the second feedforward microphone 274. In this way, the external noise of the second ear body 200 near the second sound pickup hole 215 can pass through the second sound pickup hole 215 and the second duct 2721 and reach near the sound pickup surface of the second feedforward microphone 274, and is picked up by the second feedforward microphone 274.

[0155] In other embodiments, the second ear body 200 may not be provided with the first bracket 271 and the second bracket 272. At this time, the first duct 2711 and the second duct 2721 may be formed by the third housing 210.

[0156] In other embodiments, the second ear body 200 may not be provided with the first bracket 271 and the second bracket 272. At this time, the sound pickup surface of the first feedforward microphone 273 is disposed opposite to the first sound pickup hole 214, and the sound pickup surface of the second feedforward microphone 274 is disposed opposite to the second sound pickup hole 215. The first feedforward microphone 273 picks up the external noise of the second ear body 200 through the first sound pickup hole 214. The second feedforward microphone 274 picks up the external noise of the second ear body 200 through the second sound pickup hole 215.

[0157] In some embodiments, the first sound pickup hole 214 and the second sound pickup hole 215 may be arranged at intervals in the first direction. The first sound pickup hole 214 and the second sound pickup hole 215 may be located on both sides of the second symmetry plane.

[0158] In some embodiments, the first sound pickup hole 214 and the second sound pickup hole 215 may also be symmetric about the 0-0 plane of the earphone 1000.

[0159] It can be understood that, compared with the solution where only one of the first sound pickup hole 214 or the second sound pickup hole 215 is provided, setting the first sound pickup hole 214 and the second sound pickup hole 215 symmetric about the 0-0 plane ensures that whether the user wears the earphone 1000 on the left ear or the right ear, one of the first sound pickup hole 214 and the second sound pickup hole 215 is always on the side away from the skin. This can ensure that on the premise that the user does not distinguish between the left and right ears, when the earphone 1000 is working, one of the first feedforward microphone 273 or the second feedforward microphone 274 on the side away from the user's skin can better pick up the ambient noise, and the active noise reduction effect is better. Moreover, whether the user wears the earphone 1000 on the left ear or the right ear, one of the first sound pickup hole 214 and the second sound pickup hole 215 is always facing the ground and the other is facing away from the ground. When the sound pickup hole facing away from the ground is blocked by sweat dripping in, the other sound pickup hole can still work normally to achieve active noise reduction.

[0160] It should be noted that when the first sound pickup hole 214 and the second sound pickup hole 215 are symmetric about the 0-0 plane of the earphone 1000, it can be that the center of the first sound pickup hole 214 and the center of the second sound pickup hole 215 are symmetric about the 0-0 plane. The projection of the first sound pickup hole 214 on the 0-0 plane and the projection of the second sound pickup hole 215 on the 0-0 plane can partially overlap.

[0161] In some embodiments, the line connecting the center of the first sound pickup hole 214 and the center of the second sound pickup hole 215 can form an angle with the 0-0 plane, and the angle can be in the range of 88° to 90°.

[0162] In some embodiments, the projection of the center of the first sound pickup hole on the symmetry plane is the first projection, and the projection of the center of the second sound pickup hole on the symmetry plane is the third projection, and the first projection and the third projection coincide.

[0163] In some embodiments, the projection of the first sound pickup hole 214 on the 0-0 plane and the projection of the second sound pickup hole 215 on the 0-0 plane may not completely overlap. The distance between the first projection and the third projection can be less than 0.5 mm.

[0164] The following introduces two working modes of the first feedforward microphone 273 and the second feedforward microphone 274 for active noise reduction:

[0165] (1) During the working process of the earphone 1000 for active noise reduction, the first feedforward microphone 273 and the second feedforward microphone 274 can work simultaneously, pick up the sounds near the first sound pickup hole 214 and the second sound pickup hole 215 at the same time, and through an algorithm, fuse the two channels of data and then perform active noise reduction.

[0166] (2) When the low-frequency signal of one of the first feedforward microphone 273 and the second feedforward microphone 274 is greater than the low-frequency signal of the other, the circuit switch can be used to automatically select the signal with the larger low-frequency signal as the input signal of the algorithm to perform active noise reduction. The signal with a larger low-frequency signal has less wind noise, which is conducive to improving the effect of active noise reduction.

[0167] In some embodiments, the first sound pickup hole 214 may be located on a side of the long axis L1 close to the first connection hole 218. Similarly, the second sound pickup hole 215 may be located on a side of the long axis L1 close to the first connection hole 218. For example, the first sound pickup hole 214 and the second sound pickup hole 215 may both be located on a side of the long axis L1 close to the first connection hole 218, and the first sound pickup hole 214 and the second sound pickup hole 215 may be symmetrical about the symmetry plane 0-0 of the earphone 1000. Figure 2 As shown, the first connecting hole 218 is used to allow one end of the connecting arm 300 to extend into the interior of the second earphone body 200 .

[0168] It can be understood that, compared with the solution in which the long axis L1 passes through the first sound pickup hole 214 and the second sound pickup hole 215, the first sound pickup hole 214 and the second sound pickup hole 215 are arranged on one side of the long axis L1. When the user wears the earphone 1000, the risk of sweat dripping into the first sound pickup hole 214 or the second sound pickup hole 215 can be reduced, thereby avoiding the first sound pickup hole 214 or the second sound pickup hole 215 being blocked by sweat and affecting the sound pickup effect.

[0169] In some embodiments, along the first direction, the projection of the center of the first pickup hole 214 on the symmetry plane is a first projection, the projection of the center of the first connecting hole 218 on the symmetry plane is a second projection, the distance between the first projection and the second projection is A1, and the distance between the second projection and the center of the outer surface of the second earphone body 200 is A2.

[0170] The relationship between A1 and A2 satisfies:

[0171] It is understandable that when the user wears the earphone 1000, the second earphone body 200 is located outside the user's ear and away from the first earphone body 100. The connecting arm 300 is buckled on the outer edge of the user's ear and extends from the concha cavity to the back of the ear. The distance between the first sound pickup hole 214 and the connecting arm 300 can be less than the distance between the first sound pickup hole 214 and the user's skin. The first sound pickup hole has less obstruction around it. When the microphone in the second earphone body 200 picks up sound through the first sound pickup hole 214, it is less obstructed by the outside.

[0172] like Figure 13As shown, when the second circuit board 280 is disposed between the first feedforward microphone 273 and the first bracket 271, the second circuit board 280 may be provided with a first ventilation hole 281, and the first ventilation hole 281 communicates with the first duct 2711. In this way, the sound near the first sound pickup hole 214 can pass through the first duct 2711 and the first ventilation hole 281, reach the vicinity of the sound pickup surface of the first feedforward microphone 273, and be picked up by the first feedforward microphone 273.

[0173] In some embodiments, when the second circuit board 280 is disposed between the second feedforward microphone 274 and the second bracket 272, the second circuit board 280 may be provided with a second ventilation hole (not shown in the figure). The second ventilation hole communicates with the second duct 2721.

[0174] In some embodiments, the second ear body 200 may further include a third waterproof and breathable membrane 275. The third waterproof and breathable membrane 275 may be disposed between the first bracket 271 and the first feedforward microphone 273. The third waterproof and breathable membrane 275 may cover the first duct 2711. Exemplarily, the third waterproof and breathable membrane 275 may be disposed between the first bracket 271 and the second circuit board 280. It can be understood that by providing the third waterproof and breathable membrane 275, while not affecting the sound pickup of the first feedforward microphone 273, it can also prevent external dust and moisture from entering the second ear body 200 through the first duct 2711, avoiding affecting the operation of the internal components of the second ear body 200.

[0175] In some embodiments, the second ear body 200 may further include a fourth waterproof and breathable membrane (not shown in the figure), and the fourth waterproof and breathable membrane may be fixedly connected to the second bracket 272 and cover the second duct 2721.

[0176] As Figure 13 shown, the first duct 2711 may be curved, that is, the first duct 2711 may include a curved duct. Exemplarily, the first duct 2711 may include a first section 2712 and a second section 2713. The first section 2712 communicates with the second section 2713, and the first section 2712 is connected to the end of the second section 2713 away from the first feedforward microphone 273. The central axis L3 of the first section 2712 ( Figure 13 schematically shown by a dotted line in the figure) and the central axis L4 of the second section 2713 ( Figure 13 schematically shown by a dotted line in the figure) are disposed at an angle. The first duct 2711 as a whole may be in an "L" shape or a "V" shape.

[0177] It can be understood that, compared with the first duct 2711 being a straight duct as a whole, the first duct 2711 in a bent shape can have an anti-wind noise effect. When the airflow near the first sound pickup hole 214 passes through the first duct 2711, the bent duct can buffer the airflow, and the wind noise in the sound picked up by the first feedforward microphone 273 is relatively small. In other embodiments, the first duct 2711 as a whole can also be in an "N" shape, an "S" shape, a "Z" shape or a "C" shape, etc. It can be understood that the shape of the first duct 2711 can be adjusted according to the actual situation, and the first duct 2711 can include multiple bent ducts or can also include one bent duct.

[0178] In some embodiments, the diameter of the first duct 2711 can be greater than 0.6 mm. For example, the diameter of the first duct 2711 can be 0.6 mm, 0.7 mm, 0.9 mm or 1.2 mm.

[0179] In some embodiments, the second duct 2721 can also include a bent shape. The setting manner of the second duct 2721 can refer to the setting manner of the first duct 2711, which will not be elaborated here.

[0180] In other embodiments, the first sound pickup hole 214 and the second sound pickup hole 215 can also be located on the side of the long axis L1 away from the first connection hole 218.

[0181] In other embodiments, the third housing 210 can also be provided with a third sound pickup hole (not shown in the figure) and a fourth sound pickup hole (not shown in the figure). The third sound pickup hole and the fourth sound pickup hole are located on the long axis L1 of the second ear body 200 and are symmetric about the symmetry plane 0-0 of the earphone 1000. At this time, the first bracket 271 can also further include a third duct (not shown in the figure), one end of the third duct is arranged opposite to the third sound pickup hole, and the other end communicates with the first duct 2711. The second bracket 272 can also further include a fourth duct (not shown in the figure), one end of the fourth duct is arranged opposite to the fourth sound pickup hole, and the other end communicates with the second duct 2721. In this way, the first feedforward microphone 273 can simultaneously pick up the ambient sounds near the first sound pickup hole 214 and the third sound pickup hole, and the second feedforward microphone 274 can simultaneously pick up the sounds near the second sound pickup hole 215 and the fourth sound pickup hole.

[0182] In other embodiments, the number of feedforward microphones can be one. The number of sound pickup holes can also be one. The feedforward microphone can be arranged on the connecting arm 300, and the sound pickup hole can also be arranged on the connecting arm 300. In this way, when wearing the earphone 1000, it is not necessary to distinguish between the left and right ears. At the same time, the number of one feedforward microphone can be reduced, which can reduce the volume and weight of the earphone 1000, and is beneficial to the miniaturization and light weight of the earphone 1000.

[0183] In other embodiments, the second ear body 200 may further be provided with a first microphone (not shown in the figures) and a second microphone (not shown in the figures) for calls. The first microphone and the second microphone may be used to pick up the user's speaking voice. The first microphone may pick up the user's speaking voice through the first sound pickup hole 214. The second microphone may pick up the user's speaking voice through the second sound pickup hole 215. Exemplarily, the setting manner of the first microphone may refer to the setting manner of the first feedforward microphone. The setting manner of the second microphone may refer to the setting manner of the second feedforward microphone.

[0184] As Figure 14 shown, the charging terminal 291 may include a first electrode 2911 and a second electrode 2912. Both the first electrode 2911 and the second electrode 2912 are electrically connected to the battery 240. Both the first electrode 2911 and the second electrode 2912 are embedded in the housing 209 of the second ear body 200, and one end is exposed relative to the outer surface of the housing 209 of the second ear body 200. The first electrode 2911, the second electrode 2912, the first sound pickup hole 214, and the second sound pickup hole 215 are spaced apart from each other.

[0185] Exemplarily, the first electrode 2911 may be fixedly connected to the third housing 210. One end of the first electrode 2911 may be exposed relative to the outer surface of the housing 209 of the second ear body 200 at the first charging hole 216. The second electrode 2912 may be fixedly connected to the third housing 210. One end of the second electrode 2912 may be exposed relative to the outer surface of the housing 209 of the second ear body 200 at the second charging hole 217.

[0186] In other embodiments, the first charging hole 216 and the second charging hole 217 may also be provided on the fourth housing 220, and the first electrode 2911 and the second electrode 2912 may also be fixedly connected to the fourth housing 220, and the present application does not make any restrictions.

[0187] When the user charges the earphone 1000, the first electrode 2911 and the second electrode 2912 respectively act as the positive electrode and the negative electrode, and are used to electrically connect to the positive electrode and the negative electrode of the battery 240 respectively. The present application does not fix the corresponding relationship between the first electrode 2911 and the second electrode 2912 and the positive and negative electrodes. It can be understood that the first electrode 2911 can be used as the positive electrode and the second electrode 2912 can be used as the negative electrode; or the first electrode 2911 can be used as the negative electrode and the second electrode 2912 can be used as the positive electrode.

[0188] The first electrode 2911 and the second electrode 2912 may be electrically connected to the second circuit board 280. The battery 240 may be electrically connected to the second circuit board 280. The second circuit board 280 may also be used for the electrical signal transmission between the first electrode 2911, the second electrode 2912 and the battery 240.

[0189] In some embodiments, the first electrode 2911 and the second electrode 2912 may be symmetric about the O-O plane. In this way, it is beneficial to the symmetric distribution of the weight of the second ear body 200 about the O-O plane.

[0190] As Figure 14 shown, the second ear body 200 may further include a second magnet 299. The second magnet 299 may be disposed in the second space 201 of the second ear body 200 and fixedly connected to the third housing 210. The second magnet 299 may be used to assist the quick positioning of the earphone 1000 when the earphone 1000 is charged in the paired earphone 1000 charging case. Exemplarily, the second magnet 299 may be located on a side of the battery 240 away from the first connection hole 218.

[0191] In some embodiments, the number of the second magnets 299 may be two, and the two second magnets 299 may be symmetric about the symmetry plane 0-0 of the earphone 1000.

[0192] In other embodiments, the second magnet 299 may also be fixedly connected to the fourth housing 220.

[0193] In other embodiments, the number of the second magnets 299 may also be one, or three or more.

[0194] Figure 15 is Figure 5 a schematic structural view of an embodiment of the main board bracket 250 shown in.

[0195] As Figure 15 shown, the main board bracket 250 may include a main body portion 251, an extension portion 252, a first limiting portion 253, and a second limiting portion 254. Among them, the main body portion 251 may be annular. The main body portion 251 has a first end face 2511, a second end face 2512, an inner side face 2513, and an outer side face 2514. The first end face 2511 and the second end face 2512 are arranged back to back, and the inner side face 2513 and the outer side face 2514 are arranged back to back. The inner side face 2513 is connected between the first end face 2511 and the second end face 2512. The inner side face 2513 encloses an accommodation space 255. The outer side face 2514 is connected between the first end face 2511 and the second end face 2512. The extension portion 252 is connected to the outer side face 2514 and is located at one end of the outer side face 2514 close to the first end face 2511. The first limiting portion 253 and the second limiting portion 254 are both connected to the inner side face 2513 of the main body portion 251 and are spaced apart. The first limiting portion 253 and the second limiting portion 254 divide the accommodation space 255 into a first accommodation space 2516, a second accommodation space 2517, and a third accommodation space 2518.

[0196] In some embodiments, the main board bracket 250 may further include a second positioning post 256. The second positioning post 256 may be fixedly connected to the second end face 2512 of the main body portion 251. The number of the second positioning posts 256 may be one or more. When the number of the second positioning posts 256 is more than one, the plurality of second positioning posts 256 are arranged at intervals.

[0197] Figure 16 is Figure 5 An assembly schematic diagram of an embodiment of the circuit board 261 and the main board bracket 250 shown in Figure 17 is Figure 16 A schematic structural diagram of the structure shown in

[0198] As Figure 16 and Figure 17 shown, the main board 260 may include a circuit board 261 and electronic devices 262 disposed on the circuit board 261. The circuit board 261 may serve as a carrier for electronic components. Exemplarily, the electronic components may be active devices such as chips, or passive devices such as capacitors, inductors, and resistors. It can be understood that the electronic devices 262 can be selected and combined in different types and quantities, so that the main board 260 has specific functions. Those skilled in the art can select the types and quantities of electronic components according to actual needs, and the present application does not limit this.

[0199] The circuit board 261 may be fixedly connected to the second end face 2512 of the main board bracket 250. Exemplarily, the circuit board 261 may include a first face 2611 and a second face 2612 which are opposite to each other. Among them, the first face 2611 is fixedly connected to the second end face 2512 of the main board bracket 250. The electronic devices 262 may be disposed on the first face 2611 or on the second face 2612. That is, both side surfaces of the circuit board 261 can be used to dispose the electronic devices 262, and those skilled in the art can set them according to requirements.

[0200] In some embodiments, the electronic devices 262 may include an accelerometer 2621 (accelerometer, ACC). The accelerometer 2621 may be fixedly connected to the second face 2612 of the circuit board 261. The accelerometer 2621 may be used to measure the acceleration of the second ear body 200, so as to determine the position of the second ear body 200 in space. That is, the motion state of the second ear body 200 in space can be determined by the accelerometer 2621.

[0201] In some embodiments, the electronic device 262 may further include an electrical connector 2622. The electrical connector 2622 can be used to achieve an electrical connection between the circuit board 261 and other signal transmission structures. Exemplarily, the main board 260 may include a board-to-board connector (BTB), and the board-to-board connector is fixedly connected to the second surface 2612 of the circuit board 261.

[0202] In some embodiments, the electronic device 262 may further include a main chip 2623. The main chip 2623 can be used to control the functions of the earphone 1000. Exemplarily, the main chip 2623 may be fixedly connected to the second surface 2612 of the circuit board 261.

[0203] In some embodiments, the circuit board 261 may be provided with an avoidance hole 2613 (such as Figure 16 ), when the circuit board 261 can be fixedly connected to the main board bracket 250, the second positioning post 256 can be located in the avoidance hole 2613. It can be understood that by providing the avoidance hole 2613 and the second positioning post 256, the avoidance hole 2613 and the second positioning post 256 cooperate with each other, which can help with quick positioning during the assembly process of the circuit board 261, and can also prevent the circuit board 261 from shifting during subsequent assembly processes.

[0204] Figure 18 is Figure 5 a schematic diagram of the partial structure assembly of the second ear body 200 shown in Figure 19 is Figure 18 a sectional view of an embodiment of the second ear body 200 at the section line E-E shown in

[0205] As Figure 18 and Figure 19 shown, the main board bracket 250 can be fixedly connected to the inner surface 212 of the third housing 210. The circuit board 261 of the main board 260 is fixedly connected to the main board bracket 250. In this way, the main board bracket 250 can be used to achieve the purpose of fixing the main board 260.

[0206] Exemplarily, the third housing 210 may have a boss 219. The boss 219 may be formed by protruding from the inner surface 212 of the third housing 210. The extension 252 of the main board bracket 250 can be fixedly connected to the boss 219. Along the direction from the third housing 210 to the fourth housing 220, the projection of the extension 252 on the boss 219 and the boss 219 at least partially overlap. The main board bracket 250 can be used to carry the main board 260, and can also be used to prevent the main board 260 from shaking under external forces, resulting in interference with the operation of the main board 260 and interference with other devices inside the second ear body 200.

[0207] In some embodiments, the main board 260 and the battery 240 are stacked in the Y-axis direction. Exemplarily, the main board 260 may be located on a side of the battery 240 away from the third housing 210.

[0208] In some embodiments, the battery 240 may be partially located within the second accommodation space 2517. Portions of the main board bracket 250, including the main body portion 251, the first limiting portion 253, and the second limiting portion 254, surround the battery 240. In this way, the battery 240 can be further limited in position, reducing the risk of displacement of the battery 240 in the X-Z directions.

[0209] In some embodiments, along the Y-axis direction, the antenna module 230, the battery 240, and the main board 260 may be stacked.

[0210] The second circuit board 280 is connected to and electrically connected to the main board 260. Exemplarily, the second circuit board 280 is connected to the electrical connector 2622 ( Figure 16 schematically shown in []) on the main board 260, thereby achieving electrical connection with the main board 260. It can be understood that the battery 240 can be electrically connected to the main board 260 through a flexible circuit board or conductive traces. When the user charges the earphone 1000, the current can sequentially pass through the first electrode 2911 and the second electrode 2912, the second circuit board 280, the main board 250, and finally enter the battery 240 to achieve energy storage. The second circuit board 280 can also be used to achieve electrical connection between the first feedforward microphone 273 and the second feedforward microphone 274 and the main board 250.

[0211] Figure 20 is Figure 18 a sectional view of an embodiment of the second ear body 200 shown in [] at the section line F-F.

[0212] As Figure 20 shown, along the Y-axis direction, there is a gap between the projection of the main board 260 onto the plane where the main board bracket 250 is located and the main board bracket 250. That is, a first gap 266 can be defined between the main board bracket 250 and the main board 260. The first gap 266 can be used for routing traces. Exemplarily, the feed line 2314 of the antenna module 230 can pass through the gap between the third housing 210 and the battery 240 and the first gap 266 to connect to the main board 260, thereby energizing the antenna module 230. It can be understood that by providing the first gap 266, it is possible to help fix the position of the feed line 2314 of the antenna module 230, thereby improving the reliability of the electrical connection between the antenna module 230 and the main board 260.

[0213] In other embodiments, a second gap (not shown in the figure) may also be defined between the main board bracket 250 and the main board 260, and the second circuit board 280 may also pass through the second gap and be electrically connected to the main board 260.

[0214] Figure 21 Yes Figure 5 Partial structural assembly diagram of the second ear body 200 shown in Figure 22 Yes Figure 21 Cross-sectional view of an embodiment of the structure shown in at the cross-section line G-G.

[0215] Such as Figure 21 And Figure 22 As shown in and, the second capacitance sensor 290 may be disposed on a side of the main board 260 away from the battery 240. The second capacitance sensor 290 may be spaced apart from the first feedforward microphone 273 and the second feedforward microphone 274. The second capacitance sensor 290 may be connected to the main board 260 and electrically connected to the main board 260. Exemplarily, the second capacitance sensor 290 may be electrically connected to the main board 260 through a flexible circuit board. In some embodiments, the second capacitance sensor 290 may also be referred to as a proximity sensor and may be used to detect whether the user is wearing the earphone 1000. When the second capacitance sensor 290 is close to the user's skin, the capacitance of the second capacitance sensor 290 changes, generating an electrical signal, and the distance between the second capacitance sensor 290 and the user may be determined based on the change in the electrical signal.

[0216] In some embodiments, along the Y-axis direction, the antenna module 230, the battery 240, the main board 260, and the second capacitance sensor 290 may be stacked.

[0217] Figure 23 Yes Figure 1 Structural schematic diagram of the earphone 1000 shown in at another angle.

[0218] Such as Figure 23 As shown in, the first sound pickup hole 214 and the second sound pickup hole 215 may be arranged at intervals along the first direction and are located on both sides of the first connection hole 218. The first connection hole 218 may be used to allow the end of the connecting arm 300 to extend into the second ear body 200. That is, the first sound pickup hole 214 and the second sound pickup hole 215 may be located on both sides of the connecting arm 300. The first sound pickup hole 214 and the second sound pickup hole 215 are located on a side of the long axis L1 close to the connecting arm 300.

[0219] In the present application, a headset 1000 is specifically introduced with reference to the relevant drawings. The headset 1000 includes a first ear body 100, a connecting arm 300, and a second ear body 200. The connecting arm 300 is connected between the first ear body 100 and the second ear body 200. The first ear body 100 is used for sound production. The second ear body 200 is used for picking up noise. The second ear body 200 includes a housing and a first feedforward microphone 273. The first feedforward microphone 273 is disposed inside the housing of the second ear body 200. The housing 209 of the second ear body 200 is provided with a first sound pickup hole 214. The first feedforward microphone 273 picks up the external noise of the second ear body 200 through the first sound pickup hole 214. The length of the housing 209 of the second ear body 200 in the first direction is greater than the length in the second direction. The second ear body 200 includes a major axis, which is the line connecting the two farthest endpoints of the housing 209 of the second ear body 200 in the first direction. The first sound pickup hole 214 is located on the side of the major axis close to the connecting arm 300. The second direction is different from the first direction and is the direction from the end where the connecting arm 300 is connected to the second ear body 200 towards the center of the second ear body 200.

[0220] It can be understood that compared with the solution where the major axis L1 passes through the first sound pickup hole 214, by disposing the first sound pickup hole 214 on the side of the major axis L1 close to the connecting arm 300, when the user wears the headset 1000, the risk of sweat dripping into the first sound pickup hole 214 or the second sound pickup hole 215 can be reduced, avoiding the first sound pickup hole 214 or the second sound pickup hole 215 being blocked by sweat and affecting the active noise reduction effect.

[0221] Several embodiments of the first ear body 100 will be specifically introduced below with reference to the drawings. Figure 24 is Figure 1 a schematic structural diagram of an embodiment of the first ear body 100 shown in Figure 25 is Figure 24 a partial structural exploded view of the first ear body 100 shown in

[0222] As Figure 24 and Figure 25As shown, the first ear body 100 may include a housing 109, a speaker 30, a feedback microphone 40, a bone sensor 50, a first capacitive sensor 60, a first circuit board 70, and a wire harness bracket 80. Among them, the speaker 30, the feedback microphone 40, the bone sensor 50, the first capacitive sensor 60, the first circuit board 70, and the wire harness bracket 80 may all be disposed inside the housing 109 of the first ear body 100.

[0223] Exemplarily, the housing 109 of the first ear body 100 may include a first housing 10 and a second housing 20. The first housing 10 is connected to the second housing 20 to enclose a first space 101. The speaker 30, the feedback microphone 40, the bone sensor 50, the first capacitive sensor 60, the first circuit board 70, and the wire harness bracket 80 may all be disposed within the first space 101.

[0224] In some embodiments, the housing 109 of the first ear body 100 may be spherical.

[0225] In some embodiments, the diameter of the housing 109 of the first ear body 100 may be in the range of 12 mm to 15 mm. For example, the diameter of the spherical outer surface may be 12.3 mm, 13 mm, or 14.3 mm.

[0226] Figure 26 Yes Figure 24 A partial cross-sectional view of an embodiment of the first ear body 100 shown in the cross-section line H-H.

[0227] As Figure 26 As shown, the first housing 10 may have an outer surface 11, an inner surface 12, and a first end face 13. Among them, the outer surface 11 and the inner surface 12 are disposed opposite to each other, and the inner surface 12 faces the first space 101. The first end face 13 is connected between the outer surface 11 and the inner surface 12. The second housing 20 may have an outer surface 21, an inner surface 22, and a second end face 23. Among them, the outer surface 21 and the inner surface 22 are disposed opposite to each other, and the inner surface 22 faces the first space 101. The second end face 23 is connected between the outer surface 21 and the inner surface 22.

[0228] When the first housing 10 is connected to the second housing 20, the first end face 13 of the first housing 10 is connected to the second end face 23 of the second housing 20. The outer surface 11 of the first housing 10 and the outer surface 21 of the second housing 20 can form the outer surface of the housing 109 of the first earphone body 100. The inner surface 12 of the first housing 10 and the inner surface 22 of the second housing 20 form the inner surface of the housing 109 of the first earphone body 100. The inner surface 12 of the first housing 10 and the inner surface 22 of the second housing 20 enclose a first space 101.

[0229] In some embodiments, the outer surface 11 of the first housing 10 is hemispherical, and the outer surface 21 of the second housing 20 is hemispherical. The outer surface 11 of the first housing 10 and the outer surface 21 of the second housing 20 have the same radius.

[0230] In some embodiments, the first housing 10 and the second housing 20 can be fixedly connected by means such as gluing or buckling.

[0231] As Figure 26 shown, the speaker 30 can be fixedly connected to the inner surface 12 of the first housing 10. The speaker 30 divides the first space 101 enclosed by the first housing 10 and the second housing 20 into a first sub-cavity 102 and a second sub-cavity 103. The sound-emitting surface 31 of the speaker 30 faces the first sub-cavity 102. The first housing 10 can be provided with a first through hole 14, and the first through hole 14 communicates with the external space of the first earphone body 100 (that is, the environment where the first earphone body 100 is located) and the first sub-cavity 102. The first through hole 14 is used to transmit the sound emitted by the speaker 30 out of the first earphone body 100. When the user wears the earphone 1000, the first through hole 14 is located in the concha cavity of the user, and the sound emitted by the speaker 30 can enter the user's ear through the first through hole 14 and be received by the user. Exemplarily, the first through hole 14 can be disposed opposite to the speaker 30.

[0232] In some embodiments, the first housing 10 can have a first boss 15. The first boss 15 can be located in the first sub-cavity 102. The first boss 15 can be formed by protruding from the inner surface 12 of the first housing 10 toward the first sub-cavity 102, and the surface of the first boss 15 is a part of the inner surface 12 of the first housing 10. The speaker 30 can be fixedly connected to the first boss 15. Exemplarily, the first boss 15 can be annular, and the first boss 15 surrounds and connects the speaker 30. In this way, the speaker 30 can independently separate the first sub-cavity 102 and the second sub-cavity 103, that is, the first sub-cavity 102 and the second sub-cavity 103 can be spaced apart. The first sub-cavity 102 can be used as the front sound cavity of the speaker 30, and the speaker 30 is used to transmit and interact with the outside of the first earphone body 100 through the first through hole 14. The second sub-cavity 103 can be used as the rear sound cavity of the speaker 30.

[0233] The second housing 20 may be provided with a pressure relief hole 24. The pressure relief hole 24 is used to communicate the second sub-chamber 103 with the external space of the first ear body 100 (i.e., the environment where the first ear body 100 is located) to balance the air pressure in the second sub-chamber 103. Exemplarily, the number of the pressure relief holes 24 may be two.

[0234] In some embodiments, the positions of the two pressure relief holes 24 are symmetric about the O-O plane. It can be understood that arranging the two pressure relief holes 24 symmetrically enables the user not to distinguish between the left and right ears when using the earphone 1000. Meanwhile, with the two pressure relief holes 24 symmetrically distributed, when one of the pressure relief holes 24 is blocked by sweat during wearing of the earphone 1000, there is still the other pressure relief hole 24 that can work to balance the air pressure in the second sub-chamber 103.

[0235] In some embodiments, the second housing 20 may be provided with a second connection hole 26. The second connection hole 26 communicates the outer surface 21 and the inner surface 22 of the second housing 20. As Figure 2 shown, the second connection hole 26 can be used to allow one end of the connecting arm 300 to extend into the interior of the first ear body 100.

[0236] In some embodiments, the two pressure relief holes 24 are arranged at intervals in the first direction and are located on both sides of the second connection hole 26.

[0237] In some embodiments, the connection line between the first through hole 14 and the pressure relief hole 24 is the first connection line, and the connection line between the second connection hole 26 and the first through hole 14 is the second connection line. The first connection line and the second connection line form an angle. When the speaker 30 emits sound, the sound leakage on the first connection line is greater than that on the second connection line. The first through hole 14 and the pressure relief hole 24 can form a dipole sound field. Exemplarily, when the user wears the earphone 1000, with the second connection hole 26 facing the user's front side and the two pressure relief holes 24 arranged on both sides of the second connection hole 26, the sound leakage on the user's front side can be reduced.

[0238] As Figure 26 shown, the speaker 30 may be fixed at the cross-section of the maximum diameter of the first housing 10. In other embodiments, the speaker 30 may also be fixedly connected to the inner surface 22 of the second housing 20 and at the cross-section of the maximum diameter of the second housing 20.

[0239] In some embodiments, the speaker 30 is a dual magnetic diaphragm speaker. Compared with traditional dynamic coil and dynamic iron speakers, the speaker 30 being a dual magnetic diaphragm speaker can effectively improve the low-frequency effect under the open sound field function and make up for the disadvantage that the sound outlet (i.e., the first through hole 14) of the earphone 1000 is at a certain distance from the ear canal.

[0240] In some embodiments, the first ear body 100 may further include a dust-proof net 90. The dust-proof net 90 is connected to the first housing 10 and is disposed in the first through-hole 14. The dust-proof net 90 covers the first through-hole 14. It can be understood that by providing the dust-proof net 90, impurities outside the earphone 1000 can be prevented from entering the first sub-cavity 102 of the first ear body 100 through the first through-hole 14, interfering with the operation of the speaker 30. In some embodiments, the dust-proof net 90 may be made of a metal material, so that the strength of the dust-proof net 90 is relatively good.

[0241] Exemplarily, the dust-proof net 90 may include a body portion 91 and two connecting portions 92. The connecting portions 92 are connected to the body portion 91. The two connecting portions 92 are spaced apart. The first housing 10 is provided with a second through-hole 16 and a third through-hole 17 which are spaced apart. The second through-hole 16 and the third through-hole 17 surround the first through-hole 14. The two connecting portions 92 are respectively connected to the second through-hole 16 and the third through-hole 17. The body portion 91 is a mesh structure and covers the first through-hole 14.

[0242] In some embodiments, the first ear body 100 may further include a first waterproof and breathable membrane 93. The first waterproof and breathable membrane 93 can be connected to the first housing 10 and cover the first through-hole 14. Exemplarily, the first waterproof and breathable membrane 93 may be disposed between the body portion 91 of the dust-proof net 90 and the first housing 10. It can be understood that by providing the first waterproof and breathable membrane 93, while realizing the communication between the first sub-cavity 102 and the external space of the first ear body 100 and balancing the air pressure in the first sub-cavity 102, it can also prevent external dust and moisture from entering the first sub-cavity 102 through the first through-hole 14, avoiding affecting the operation of the speaker 30.

[0243] In some embodiments, the area of the first through-hole 14 is in the range of 5 mm 2 to 8 mm 2 . For example, the area of the first through-hole can be 5 mm 2 , 6.5 mm 2 or 8 mm 2 .

[0244] In some embodiments, the first ear body 100 may further include a second waterproof and breathable membrane 94. The second waterproof and breathable membrane 94 is connected to the inner surface 22 of the second housing 20 and covers the pressure relief hole 24. It can be understood that by providing the second waterproof and breathable membrane 94, while realizing the communication between the second sub-cavity 103 and the external space of the first ear body 100 and balancing the air pressure in the second sub-cavity 103, it can also prevent external dust and moisture from entering the second sub-cavity 103 through the first through-hole 14, avoiding affecting the operation of the internal components of the first ear body 100.

[0245] In some embodiments, the number of pressure relief holes 24 is two, and the number of the second waterproof and breathable membranes 94 is also two. The two pressure relief holes 24 and the two second waterproof and breathable membranes 94 are arranged in one-to-one correspondence.

[0246] In some embodiments, the area of the pressure relief hole 24 is smaller than the area of the first through hole 14. When the number of pressure relief holes 24 is multiple, the area of the pressure relief hole 24 is the sum of the areas of the multiple pressure relief holes 24.

[0247] In some embodiments, the area of the pressure relief hole 24 is in the range of 1 mm 2 to 3 mm 2 . For example, the area of the pressure relief hole 24 can be 1 mm 2 , 2 mm 2 or 3 mm 2 .

[0248] Figure 27 is Figure 24 a partial sectional view of an embodiment of the first ear body 100 shown in the sectional view along the section line I-I.

[0249] As Figure 27 shown, the feedback microphone 40 can be disposed near the sound-emitting position of the speaker 30. Exemplarily, the feedback microphone 40 can be disposed in the first sub-cavity 102. The feedback microphone 40 can be disposed around the first through hole 14. When the user wears the earphone 1000, the feedback microphone 40 can be located in the concha cavity of the user's ear, near the ear canal. The sound near the user's ear canal can be picked up by the feedback microphone 40 through the first through hole 14. It can be understood that by providing the feedback microphone 40 and disposing the feedback microphone 40 near the speaker 30, the feedback microphone 40 can be used to pick up the noise entering near the user's ear canal, and the sound on the speaker 30 side is fed back to the chip to output an anti-phase sound wave to cancel the ear noise, and the user experience is better.

[0250] In some embodiments, the first ear body 100 may further include a first magnet 95. Exemplarily, the first magnet 95 can be located in the first sub-cavity 102 and fixedly connected to the inner wall surface of the first housing 10. When the earphone 1000 is received in the earphone case, the first magnet 95 can be used to cooperate with the magnet in the earphone case to generate a suction force to fix the position of the first ear body 100 in the earphone 1000 case.

[0251] In some embodiments, the first magnet 95 is a long strip with a curvature. In this way, the first magnet can fit more closely to the hemispherical first housing 10, and the device arrangement in the first sub-cavity 102 can be more compact. In other embodiments, the first magnet 95 can be other shapes such as circular.

[0252] Figure 28 isFigure 25 Schematic structural diagram of an embodiment of the wire harness bracket 80 shown in Figure 29 is Figure 28 Schematic structural diagram of the wire harness bracket 80 shown in at another angle.

[0253] As Figure 28 and Figure 29 shown, the wire harness bracket 80 may include a bracket body 81 and a plurality of baffles 82. The bracket body 81 includes a top surface 811, a bottom surface 812, and a peripheral side surface 813. The top surface 811 and the bottom surface 812 are arranged opposite to each other, and the peripheral side surface 813 is connected between the top surface 811 and the bottom surface 812. The wire harness bracket 80 is provided with a wire threading channel 83, a first ventilation duct 84, and a second ventilation duct 85. The wire threading channel 83, the first ventilation duct 84, and the second ventilation duct 85 are arranged at intervals and are not connected to each other. Among them, the wire threading channel 83 communicates with the top surface 811 and the bottom surface 812. The first ventilation duct 84 communicates with the bottom surface 812 and the peripheral side surface 813. The second ventilation duct 85 communicates with the bottom surface 812 and the peripheral side surface 813. The top surface 811 of the bracket body 81 is the top surface of the wire harness bracket 80. The peripheral side surface 813 of the bracket body 81 is the peripheral side surface of the wire harness bracket 80.

[0254] A plurality of baffles 82 are fixedly connected to the bottom surface 812 of the bracket body 81. The plurality of baffles 82 surround the wire threading channel 83 and are spaced apart from each other. It can be understood that the number of baffles 82 can be adjusted according to actual conditions.

[0255] In some embodiments, the wire harness bracket 80 may be provided with a receiving groove 86. The receiving groove 86 can be used to place the bone sensor 50. Exemplarily, the receiving groove 86 may form an opening on the bottom surface 812 and the peripheral side surface 813 of the bracket body 81. The receiving groove 86 may be arranged at intervals from the wire threading channel 83, the first ventilation duct 84, and the second ventilation duct 85.

[0256] Figure 30 is Figure 24 Partial sectional view of an embodiment of the first ear body 100 shown in at the section line H-H.

[0257] As Figure 30As shown, the wire harness bracket 80 is fixedly connected to the inner surface 22 of the second housing 20. Exemplarily, the circumferential side surface 813 of the wire harness bracket 80 is connected to the inner surface 22 of the second housing 20. It can be understood that the circumferential side surface 813 of the wire harness bracket 80 can be designed according to the shape of the inner surface 22 of the second housing 20, so that the shape of the circumferential side surface 813 generally matches the shape of the inner surface 22 of the second housing 20. For example, the wire harness bracket 80 can be generally frustum-shaped. In this way, the connection area between the wire harness bracket 80 and the second housing 20 can be increased, and the connection strength can be enhanced. In some embodiments, the wire harness bracket 80 can be fixedly connected to the second housing 20 by gluing.

[0258] The bottom surface 812 of the bracket body 81 faces the speaker 30. The first ventilation duct 84 and the second ventilation duct 85 can be respectively disposed opposite to and communicated with the two pressure relief holes 24. In this way, the second sub-chamber 103 can be communicated with the outside through the first ventilation duct 84, the second ventilation duct 85 and the two pressure relief holes 24, so as to achieve the air pressure balance in the second sub-chamber 103.

[0259] In some embodiments, the second connection hole 26 is disposed opposite to the wire threading channel 83 of the wire harness bracket 80.

[0260] Figure 31 Yes Figure 25 is an assembly schematic diagram of an embodiment of the bone sensor 50 and the wire harness bracket 80 shown in Figure 32 Yes Figure 24 is a partial sectional view of an embodiment of the first ear body 100 at the section line I-I shown in

[0261] As Figure 31 and Figure 32 shown, the bone sensor 50 can be fixedly connected to the accommodation groove 86 of the wire harness bracket 80. Exemplarily, the accommodation groove 86 can form openings on the bottom surface 812 and the circumferential side surface 813 of the bracket body 81. The bone sensor 50 can be fixedly connected to the space enclosed by the accommodation groove 86 of the wire harness bracket 80 and the second housing 20.

[0262] The second ear body 200 may further include a buffer member 99. The buffer member 99 can be filled in the gap between the second housing 20, the bone sensor 50 and the wire harness bracket 80. In this way, the buffer member 99 can help to fix the position of the bone sensor 50 and play a buffering role when subjected to external force impact. Exemplarily, the buffer member 99 can be glue. In this way, while the buffer member 99 plays a buffering role, it can also strengthen the connection between the wire harness bracket 80 and the second housing 20 and improve the reliability.

[0263] The first capacitive sensor 60 is disposed within the first space 101. Exemplarily, the first capacitive sensor 60 can be connected to the inner surface 22 of the second housing 20. It can be understood that in some embodiments, the first capacitive sensor 60 can also be referred to as a proximity sensor and can be used to detect whether the user is wearing the earphone 1000. When the first capacitive sensor 60 is close to the user's skin, the capacitance of the first capacitive sensor 60 changes, generating an electrical signal, and the distance between the first capacitive sensor 60 and the user can be determined based on the change in the electrical signal.

[0264] Figure 33 Is Figure 25 A schematic structural diagram of an embodiment of the first circuit board 70 shown in

[0265] As Figure 33 Shown, the first circuit board 70 can include a first portion 71, a second portion 72, a third portion 73, a fourth portion 74, a fifth portion 75, and a sixth portion 76. Among them, the second portion 72 is connected between the first portion 71 and the third portion 73. The third portion 73 is connected between the second portion 72 and the fourth portion 74. The fourth portion 74 is connected between the third portion 73 and the fifth portion 75. The sixth portion 76 is connected to the fourth portion 74.

[0266] In some embodiments, the first portion 71, the second portion 72, the third portion 73, the fourth portion 74, the fifth portion 75, and the sixth portion 76 can be an integral structural member. For example, the first circuit board 70 can employ a flexible circuit board. In this way, the first circuit board 70 can be cut into any shape according to the devices to be connected and their positions, and then after the corresponding portions are connected to the corresponding devices, it can be bent into a preset shape. Compared with the solution of achieving electrical connection through structures such as cables, the flexible circuit board has a lower assembly difficulty and better electrical connection reliability. In other embodiments, the first portion 71, the second portion 72, the third portion 73, the fourth portion 74, the fifth portion 75, and the sixth portion 76 can also be connected by wires.

[0267] Figure 34 Is Figure 24 A partial structural schematic diagram of an embodiment of the first earphone body 100 shown in Figure 35 Is Figure 34 A structural schematic diagram of the structure shown in at another angle.

[0268] As Figure 34 And Figure 35As shown, the feedback microphone 40 is connected to the first part 71 of the first circuit board 70 and electrically connected to the first part 71. The speaker 30 is connected to the third part 73 of the first circuit board 70 and electrically connected to the third part 73. The fourth part 74 can be fixed to the bottom surface of the wire harness bracket 80. The first capacitance sensor 60 is connected to the fifth part 75 of the first circuit board 70 and electrically connected to the fifth part 75. The bone sensor 50 is connected to the sixth part 76 of the first circuit board 70 and electrically connected to the sixth part 76.

[0269] The fourth part 74 can be used to connect a signal wire to transmit the signals of the speaker 30, the wire harness bracket 80, the bone sensor 50, the first capacitance sensor 60, and the feedback microphone 40 to the second ear body 200.

[0270] Figure 36 is Figure 27 An enlarged schematic diagram of an embodiment of the structure shown in [FIGURE] at J.

[0271] As Figure 36 shown, the first housing 10 of the first circuit board 70 can be connected to the inner surface 12 of the first housing 10. The feedback microphone 40 is connected to the side surface of the first part 71 away from the first housing 10. In the X-axis direction, the first part 71 can be disposed opposite to the first through hole 14. Exemplarily, the first part 71 can be provided with a through hole 711. In the X-axis direction, the through hole 711 can be disposed opposite to and communicated with the first through hole 14.

[0272] In some embodiments, the first housing 10 can be provided with positioning posts 19. The positioning posts 19 can be disposed in the first sub-cavity 102. The positioning posts 19 can be used to assist in quickly positioning the first part 71 during the process of installing the first part 71 to the first housing 10. The first part 71 can correspondingly be provided with positioning holes 712, and at least part of the positioning posts 19 are located in the positioning holes 712. The positioning holes 712 and the through holes 711 can be communicated or spaced apart.

[0273] In some embodiments, the first circuit board 70 can further include a first reinforcing plate 77. The first reinforcing plate 77 is connected to the side surface of the first part 71 away from the feedback microphone 40. Exemplarily, the feedback microphone 40 is connected to the side surface of the first part 71 away from the first housing 10. The first reinforcing plate 77 is connected between the first part 71 and the first housing 10. The first reinforcing plate 77 is used to reinforce the first part 71. In other embodiments, a reinforcing plate (not shown in the figure) can also be provided at other positions of the first circuit board 70 to increase the local strength of the first circuit board 70.

[0274] Figure 37 is Figure 1 A cross-sectional view of an embodiment of the earphone 1000 shown in [FIGURE] at the O-O plane.

[0275] like Figure 37 As shown, the bone sensor 50 of the first earphone body 100 is connected to the side of the harness bracket 80 close to the second earphone body 200. When the user wears the earphone 1000, the first earphone body 100 is clamped in the user's concha cavity, and the second earphone body 200 is located outside the user's ear and away from the first earphone body 100. That is, the user's ear is located between the first earphone body 100 and the second earphone body 200. The bone sensor 50 of the first earphone body 100 is connected to the side of the harness bracket 80 close to the second earphone body 200, so that the bone sensor 50 can be closer to the user's ear, and can better pick up the vibration of the user's speech, which is beneficial to call noise reduction.

[0276] The third housing 210 of the second earphone body 200 is connected to the side of the fourth housing 220 away from the first earphone body 100. The antenna module 230 is fixedly connected to the third housing 210. The antenna module 230 can be located on the side of the second earphone body 200 away from the ear tissue. In this way, the antenna module 230 is less interfered when transmitting and receiving signals during operation.

[0277] The first capacitive sensor 60 may be located inside the housing 109 of the first earphone body 100. The second capacitive sensor 290 may be located inside the housing 209 of the second earphone body 200. The second earphone body 200 may further include a controller, and the controller may be electrically connected to the first capacitive sensor 60 and the second capacitive sensor 290. Exemplarily, the controller may be located in the main chip 2623 ( Figure 16 (indicated in the figure) above.

[0278] Exemplarily, the first capacitive sensor 60 is connected to the inner surface 22 of the second housing 20 and is located on a side of the inner surface 22 close to the second earphone body 200. The second capacitive sensor 290 is connected to the inner surface 222 of the fourth housing 220. That is, the second capacitive sensor 290 is located on a side of the second earphone body 200 close to the first earphone body 100. In this way, when the user wears the earphone 1000, the first capacitive sensor 60 and the second capacitive sensor 290 are closer to the user's ears, and the detection results of the first capacitive sensor 60 and the second capacitive sensor 290 are more accurate.

[0279] The earphone 1000 is provided with a first capacitance sensor 60 on the first earphone body 100 and a second capacitance sensor 290 on the second earphone body 200. The first capacitance sensor 60 is used to obtain a first capacitance value in a first environment, and the second capacitance sensor 290 is used to obtain a second capacitance value in a second environment. The controller is used to determine whether the user wears the earphone 1000 according to the first capacitance value and the second capacitance value, that is, the wearing detection of the earphone 100. Exemplarily, the wearing detection may include the following three scenarios:

[0280] (1) When the user wears the headset 1000 correctly, the first capacitance sensor 60 and the second capacitance sensor 290 can be in close contact with the user's auricle and form a specific capacitance value according to the pressure. At the same time, the first capacitance sensor 60 and the second capacitance sensor 290 are both close to the user's ear, and the difference between the first capacitance value generated by the first capacitance sensor 60 and the second capacitance value generated by the second capacitance sensor 290 is small.

[0281] Exemplarily, when the user wears the earphone 1000 correctly, the first earphone body 100 can be stuck in the user's concha cavity, and the first environment is the user's concha cavity. The second earphone body 200 is located outside the user's ear and away from the side of the first earphone body 100. The second environment is the side outside the user's ear and away from the first earphone body 100.

[0282] (2) When the user is not wearing the headset 1000 and there is no shielding between the first capacitance sensor 60 and the second capacitance sensor 290, the pressure on the first capacitance sensor 60 and the second capacitance sensor 290 is relatively small, and the first capacitance sensor 60 generates a specific first capacitance value. The second capacitance sensor 290 generates a specific second capacitance value. The difference between the first capacitance value generated by the first capacitance sensor 60 and the second capacitance value generated by the second capacitance sensor 290 is relatively small;

[0283] (3) When the user picks up the headset 1000 or other obstacles cover either the first capacitive sensor 60 or the second capacitive sensor 290, one of the first capacitive sensor 60 and the second capacitive sensor 290 is closer to the obstacle and the other is farther away. At this time, the difference between the capacitance value generated by the first capacitive sensor 60 and the capacitance value generated by the second capacitive sensor 290 is large.

[0284] It can be understood that the controller can determine whether the headset 1000 is in the (1) scene or the (2) scene based on the absolute value of the capacitance generated by the first capacitance sensor 60 and the second capacitance sensor 290, and determine whether the headset 1000 is in the (3) scene based on the difference in capacitance generated by the first capacitance sensor 60 and the second capacitance sensor 290 (that is, the relative value of the capacitance).

[0285] It can be understood that compared with the solution of only setting the first capacitive sensor 60 or the second capacitive sensor 290, the present application sets the first capacitive sensor 60 on the first earphone body 100 and the second capacitive sensor 290 on the second earphone body 200. This can reduce the risk of accidental touch and improve the wearing detection accuracy of the earphone 1000.

[0286] like Figure 37As shown, along the length direction of the connecting arm 300, the connecting arm 300 has a first end portion and a second end portion which are spaced apart. The first end portion is connected to the first earphone body 100, and the second end portion is connected to the second earphone body 200. In some embodiments, the central axis directions of the first end portion and the second end portion are arranged at an angle, and the range of the angle is within the range of 11.4° to 26°. For example, the angle can be 11.4°, 15°, 20° or 26°. It can be understood that, compared with the scheme in which the central axis directions of the first end portion and the second end portion of the connecting arm 300 are arranged in parallel, when the first end portion and the second end portion of the connecting arm 300 are arranged at a certain angle, when the user wears the earphone 1000, the relative positions of the first earphone body 100 and the second earphone body 200 can better fit the inclination angle and contour curve of the user's ear, effectively reducing the pressing feeling of the first earphone body 100 and the second earphone body 200 of the earphone 1000 on the earphone 1000, and the user experience is better.

[0287] Several embodiments of the connecting arm 300 will be specifically introduced below with reference to the accompanying drawings. Figure 38 is Figure 1 A sectional view of an embodiment of the connecting arm 300 shown in at the section line K-K. Figure 39 is Figure 38 A sectional view of an embodiment of the connecting arm 300 shown in at the section line L-L. Figure 40 is Figure 38 A sectional view of an embodiment of the connecting arm 300 shown in at the section line M-M.

[0288] As Figure 38 , Figure 39 and Figure 40 shown, the connecting arm 300 may include a first connecting member 310, a second connecting member 320, a support member 330, a wire harness 340 and a tube body 350. The tube body 350 is sleeved on the support member 330 and the wire harness 340, for protecting the support member 330 and the wire harness 340, and can also be used for insulating the wire harness 340. The support member 330 is used to make the connecting arm 300 assume a preset shape. The wire harness 340 is used to transmit electrical signals.

[0289] Exemplarily, the tube body 350 is provided with a first channel 351 and a second channel 352 which are spaced apart. Both the first channel 351 and the second channel 352 are arranged along the length direction of the tube body 350. The tube body 350 has a first end and a second end which are oppositely arranged. The first connecting member 310 is connected to the first end, and the second connecting member 320 is connected to the second end. Among them, the end face of the first end of the tube body 350 is the first end face 353. The end face of the second end of the tube body 350 is the second end face 354.

[0290] In some embodiments, the tube body 350 may be made of an insulating material. For example, thermoplastic polyurethane elastomer rubber (TPU).

[0291] As Figure 39 shown, the wire harness 340 may be located in the middle of the first channel 351, and both ends are exposed at the first end face 353 and the second end face 354 respectively. In some embodiments, the first connector 310 may be provided with a first through hole 314. The first through hole 314 penetrates the first connector 310 along the length direction of the first connector 310. The second connector 320 may be provided with a second through hole 321. The second through hole 321 penetrates the second connector 320 along the length direction of the first connector 310. One end of the support member 330 may pass through the first through hole 314 and be exposed, and the other end may pass through the second through hole 321 and be exposed.

[0292] As Figure 40 shown, the first connector 310 may be provided with a first cavity 315. The first cavity 315 and the first through hole 314 may be spaced apart. The second connector 320 may be provided with a second cavity 322. The second cavity 322 and the second through hole 321 may be spaced apart. The support member 330 may be located in the middle of the second channel 352. One end of the support member 330 may be located in the first cavity 315, and the other end may be located in the second cavity 322.

[0293] In some embodiments, the support member 330 may be a deformable metal material, specifically a metal strip. It may also be an elastic metal or other materials. Exemplarily, the support member 330 may be a metal wire made of shape memory alloy. It can be understood that, compared with the solution of using ordinary metal materials to prepare the support member 330, using shape memory alloy to prepare the support member 330 can keep the first end and the second end of the connecting arm 300 always within a certain distance range, avoiding the support member 330 losing its initial shape after being stretched multiple times.

[0294] In some embodiments, the central axis direction of the first connector 310 is substantially the same as the central axis direction of the first end of the connecting arm 300, and the central axis direction of the second connector 320 is substantially the same as the central axis direction of the second end of the connecting arm 300. The central axis direction of the first connector 310 and the central axis direction of the second connector 320 may also be set at an angle. The angle range is within 11.4° to 26°, for example, the angle may be 11.4°, 15°, 20° or 26°.

[0295] It can be understood that the axial direction of the first connecting member 310 and the axial direction of the second connecting member 320 can be realized by the shape of the support member 330 made of shape memory alloy. First, a preset shape is set for the support member 330 made of shape memory alloy, and then the support member 330 is passed through the first channel 351 of the tube body 350, with one end fixedly connected to the first connecting member 310 and the other end fixedly connected to the second connecting member 320. Then, the support member 330 is restored to the preset shape under specific conditions. At this time, the shape of the tube body 350 can change with the change of the shape of the support member 330, and finally the axial directions of the first connecting member 310 and the second connecting member 320 can be set at a preset included angle.

[0296] In some embodiments, the axial direction of the first end of the tube body 350 and the axial direction of the second end of the tube body 350 can also be set at an included angle.

[0297] As Figure 38 shown, there is a gap between the wire harness 340 and the wall surface of the first channel 351. It can be understood that by providing a gap between the first channel 351 and the wire harness 340, when the connecting arm 300 is bent, the degree of deformation of the wire harness 340 can be smaller than the degree of deformation of the tube body 350. In other words, when the connecting arm 300 is bent, the stretching amount of the wire harness 340 is less than the stretching amount of the tube body 350. In this way, the wire harness 340 is not easily broken and has a longer lifespan.

[0298] It can be understood that the connecting arm 300 can be used to connect the first ear body 100 and the second ear body 200 and realize signal transmission between the first ear body 100 and the second ear body 200. Below, a specific embodiment of the connecting arm 300 connecting the first ear body 100 and the second ear body 200, as well as a specific embodiment of the connecting arm 300 for realizing signal transmission between the first ear body 100 and the second ear body 200, will be specifically introduced through the drawings.

[0299] As Figure 37 shown, when the connecting arm 300 is connected between the first ear body 100 and the second ear body 200, the first connecting member 310 is connected to the first ear body 100. The second connecting member 320 is connected to the second ear body 200.

[0300] Figure 41 is Figure 37 an enlarged view of an embodiment of the structure shown in at N.

[0301] As Figure 37 and Figure 41 shown, the first connecting member 310 can include a body portion 311, a first protrusion 312, and a second protrusion 313 ( Figure 41In the figure, the body part 311, the first protrusion 312, and the second protrusion 313 are schematically distinguished by dashed lines). The first protrusion 312 and the second protrusion 313 are fixedly connected to the side surface 3111 of the body part 311. Along the length direction of the first connecting member 310, the first protrusion 312 and the second protrusion 313 are arranged at intervals. One end of the first connecting member 310 is connected to the pipe body 350, and the other end is connected to the first ear body 100.

[0302] Exemplarily, the wall surface 3511 of the first channel 351 can be recessed to form a first groove 355. The first groove 355 and the first end surface 353 are arranged at intervals. The first protrusion 312 of the first connecting member 310 and a part of the body part 311 can be located in the first groove 355. At the same time, along the length direction of the first connecting member 310, a part of the first end surface 353 is located between the first protrusion 312 and the second protrusion 313. It can be understood that the first protrusion 312 can be used as a limiting structure to prevent the pipe body 350 from falling off the first connecting member 310.

[0303] The first groove 355 can communicate with the first channel 351. When the first connecting member 310 is fixedly connected to the pipe body 350, the first through hole 314 communicates with the first channel 351. In this way, one end of the wire harness 340 can pass through the first through hole 314 and then enter the second sub-cavity 103 of the first ear body 100.

[0304] In some embodiments, the first protrusion 312 can be annular and sleeved on the side surface 3111 of the body part 311. In other embodiments, the first protrusion 312 can also include a plurality of sub-protrusions, and the plurality of sub-protrusions are spaced apart and circumferentially connected to the side surface 3111 of the body part 311.

[0305] In some embodiments, when the pipe body 350 is made of TPU, the TPU material has elasticity, and the size of the first groove 355 can be designed to be slightly smaller than the first protrusion 312 of the first connecting member 310. Furthermore, the wall surface of the first groove 355 can abut against the first protrusion 312 and the body part 311, and the connection strength between the pipe body 350 and the first connecting member 310 is better.

[0306] In some embodiments, when the first connecting member 310 is connected to the first ear body 100, the first connecting member 310 is connected to the second housing 20. Exemplarily, a part of the first connecting member 310 is located in the wire threading channel 83 of the wire harness bracket 80 and the second connecting hole 26 of the second housing 20. A convex block 831 may be formed by protruding the inner wall surface of the wire threading channel 83 of the wire harness bracket 80. Along the length direction of the first connecting member 310, the convex block 831 is located between the first protrusion 312 and the second protrusion 313 of the first connecting member 310 and is adjacent to the first end face 353 of the tube body 350. It can be understood that the convex block 831 of the wire harness bracket 80 can serve as a limiting structure to prevent the first connecting member 310 from falling off the first ear body 100 along the X-axis direction.

[0307] It can be understood that the manner in which the second connecting member 320 connects the tube body 350 and the second ear body 200 may refer to the connection manner of the first connecting member 310 connecting the tube body 350 and the first ear body 100, which will not be elaborated here. When the second connecting member 320 is connected to the second ear body 200, the second connecting member 320 may be fixedly connected to the third housing 210 of the second ear body 200.

[0308] In some embodiments, a part of the first end of the tube body 350 may also be located in the third through hole 17. At this time, the tube body 350 is located between the second housing 20 and the first connecting member 310.

[0309] In some embodiments, there may be a third gap S1 between the connecting arm 300 and the first ear body 100. Exemplarily, the third gap S1 may be surrounded by the first connecting member 310, the first end face 353 of the tube body 350, and the inner wall surface of the wire threading channel 83 of the wire harness bracket 80. When the first connecting member 310 is fixedly connected to the first ear body 100 by gluing, glue can be injected into the third gap S1 to achieve the fixed connection between the first connecting member 310 and the first ear body 100. Similarly, there may also be a fourth gap S2 (not shown in the figure) between the second connecting member 320 and the second ear body 200. When the second connecting member 320 is also fixedly connected to the second ear body 200 by gluing, glue can be injected into the fourth gap S2 to achieve the fixed connection between the second connecting member 320 and the second ear body 200.

[0310] In some embodiments, the third gap S1 may be greater than the fourth gap S2. It can be understood that during the assembly process of the connecting arm 300, the first ear body 100, and the second ear body 200, due to assembly tolerances, when the angle between the central axis direction of the first end of the tube body 350 and the central axis direction of the second end of the tube body 350 fails to reach the preset ideal angle, fine adjustment can be performed at this time through the third gap S1 between the first connector 310 and the first ear body 100. It should be noted that when the first connector 310 and the first ear body 100 are fixedly connected by glue, the fine adjustment process needs to be completed before the glue solidifies.

[0311] In other embodiments, the third gap S1 may be less than the fourth gap S2. At this time, fine adjustment can be performed through the fourth gap S2 between the second connector 320 and the second ear body 200.

[0312] Figure 42 Yes Figure 38 It is a sectional view of an embodiment of the wire harness 340 shown in the cross-section line P-P.

[0313] As Figure 42 As shown, the wire harness 340 may be a collection of multiple signal lines 341. Exemplarily, the wire harness 340 may include multiple signal lines 341 and a first encapsulation member 342. The first encapsulation member 342 is provided with a first installation channel 4321 along the length direction. The middle part of the signal line 341 may be located within the first installation channel 4321, and both ends are exposed outside the first installation channel 4321. The first encapsulation member 342 can be used to make the 9 signal lines 341 into a whole, which is convenient for installation.

[0314] In some embodiments, the wire harness 340 may include 9 signal lines. The 9 signal lines 341 are respectively 1 signal line 341 for transmitting power, 1 signal line 341 for grounding, 2 signal lines 341 for connecting a capacitive sensor, 2 signal lines 341 for connecting a feedback microphone, 2 signal lines 341 for connecting a bone sensor, and 2 signal lines 341 for connecting a speaker. It can be understood that the number and types of the signal lines 341 included in the wire harness 340 can be adjusted according to the devices provided in the first ear body 100, and the present application does not make any limitations.

[0315] In some embodiments, the signal line 341 for transmitting power is the first signal line, and the signal line 341 for connecting the speaker is the second signal line. The wire harness 340 may further include a second encapsulation member 343. The second encapsulation member 343 can be used to separately encapsulate the two signal lines 341 for connecting the speaker 30, so that they form an integral body. The second encapsulation member 343 is provided with a second installation channel 3431 in the length direction. The two first signal lines are assembled in the second installation channel 3431, and both ends are exposed from the second installation channel 3431. At this time, the two first signal lines and the second encapsulation member 343 constitute a sub-wire harness. The sub-wire harness and the first signal line are jointly assembled in the first installation channel 4321.

[0316] It can be understood that the signal of the speaker 30 is easily affected by other signals and has a high requirement for crosstalk. By separately wrapping the signal line 341 of the speaker 30 with the second encapsulation member 343, that is, the two signal lines 341 for connecting the speaker 30 are independently arranged. Then, together with other signal lines 341, they are wrapped by the first encapsulation member 342. The signal of the speaker 30 is not easily interfered by the lines of other signals, and the sound effect of the earphone 1000 is better. In other embodiments, the signal lines of the bone sensor also have a high requirement for crosstalk. Therefore, the two signal lines 341 for connecting the bone sensor can also be independently arranged. At this time, the wire harness 340 may further include a third encapsulation member (not shown in the figure), and the third encapsulation member can be used to wrap the two signal lines 341 for connecting the bone sensor.

[0317] In some embodiments, the signal lines 341 with lower crosstalk requirements in the signal lines 341 can adopt the form of twisted pairs. For example, the two signal lines 341 for connecting the capacitive sensor adopt the form of twisted pairs. It can be understood that compared with the scheme of separately arranging the two signal lines 341 for connecting the capacitive sensor, the two signal lines 341 for connecting the capacitive sensor adopting the form of twisted pairs can reduce the gap between the two signal lines 341, which can greatly reduce the cross-sectional area of the wire harness 340, and then the connecting arm 300 can be set thinner.

[0318] In some embodiments, the two signal lines 341 for connecting the feedback microphone 40 can also adopt the form of twisted pairs.

[0319] Figure 43 It is an assembly schematic diagram of an embodiment of the wire harness 340, the first circuit board 70, and the second circuit board 280.

[0320] As Figure 43 shown, one end of the wire harness 340 is connected to the first circuit board 70 and is electrically connected to the first circuit board 70. The other end of the wire harness 340 is connected to the second circuit board 280 and is electrically connected to the second circuit board 280. Combining Figure 13 andFigure 14 It can be known that the feedback microphone 40, the speaker 30, the first capacitance sensor 60 and the bone sensor 50 in the first ear body 100 are all electrically connected to the first circuit board 70. Combining Figure 30 and Figure 31 It can be known that the second circuit board 280 is electrically connected to the main board 260. In this way, the signals of the feedback microphone 40, the speaker 30, the first capacitance sensor 60 and the bone sensor 50 in the first ear body 100 can be transmitted to the main board 260 of the second ear body 200 through the wire harness 340. The wire harness 340 can be used to transmit electrical signals between the first ear body 100 and the second ear body 200.

[0321] Figure 44 FIG. is an assembly schematic diagram of an implementation manner of the wire harness 340, the first circuit board 70 and the wire harness bracket 80.

[0322] As Figure 44 shown, the wire harness bracket 80 may include a bracket body 81 and a plurality of baffles 82. The fourth part 74 of the first circuit board 70 is fixed to the bottom surface 812 of the bracket body 81. When the wire harness 340 includes a plurality of signal lines 341, the plurality of signal lines 341 may pass through the wire passing channel 83 of the wire harness bracket 80, enter the side of the bottom surface 812 of the bracket body 81, and then be electrically connected to the fourth part 74 of the first circuit board 70. The plurality of signal lines 341 and the plurality of baffles 82 are arranged alternately in sequence, that is, a baffle 82 is provided between two adjacent signal lines 341. The baffle 82 can be used to comb the plurality of signal lines 341, separate the plurality of signal lines 341 from each other, and reduce the interference between the signal lines 341.

[0323] Figure 45 FIG. is a schematic structural diagram of an implementation manner of the audio device 3000 provided by the present application.

[0324] As Figure 45 shown, the present application also provides an audio device 3000, and the audio device 3000 includes a headset 1000 and a headset case 2000. The headset is disposed in the headset case 2000. The headset case 2000 can be used to store the headset 1000. In some implementation manners, the headset case 2000 can also be used to charge the headset 1000.

[0325] In some implementation manners, the number of headsets 1000 included in the audio device 3000 may be two.

[0326] It should be noted that, without conflict, the embodiments and features in the embodiments of the present application can be combined with each other, and any combination of features in different embodiments is also within the protection scope of the present application. That is to say, the above-described multiple embodiments can also be arbitrarily combined according to actual needs.

[0328] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application.
