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, the present application arranges the first sound pickup hole and the second sound pickup hole at intervals along 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 arranged symmetrically about 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 sound through the first sound pickup hole and the second sound pickup hole for active noise reduction or calling, whether the user wears the earphone on the right ear or the left ear, the first sound pickup hole and the second sound pickup hole always keep one facing the ground and the other facing the side away from the ground. The interference effect received during the sound pickup process is consistent and does not change due to the change of spatial position. The sound pickup effect of the second earphone body is basically the same, and the sound output effect of the earphone is also basically the same. In addition, when the user uses the earphone, whether the user wears the earphone on the right ear or the left ear, the position of the first sound pickup hole and the second sound pickup hole is the same from the appearance. The user does not need to distinguish between the left and right ears when using the earphone.

[0009] In a possible implementation, the second earphone body includes a long axis, which is a line connecting two farthest end points of the housing of the second earphone body in the first direction. The first sound pickup hole and the second sound pickup hole are located on one side of the long axis close to the connecting arm.

[0010] It can be understood that when the user wears the earphones, the long axis direction can be roughly perpendicular to the bottom surface direction. When the user wears the earphones, when sweat drips onto the second earphone shell, compared with the solution in which the first sound pickup hole and the second sound pickup hole are arranged on the long axis, the first sound pickup hole and the second sound pickup hole are arranged on the side of the long axis L1 close to the connecting arm. The sweat can slide along the curve of the shell, which can reduce the risk of sweat dripping directly into the first sound pickup hole or the second sound pickup hole, thereby avoiding the first sound pickup hole or the second sound pickup hole being blocked by sweat and 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 outside the user's ear and away from the first earphone body. The connecting arm is buckled on the outer edge of the user's ear and extends from the concha cavity to the back of the ear. 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. Compared with the solution in which the first sound pickup hole and the second sound pickup hole are located 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 away from the user's skin, and there are fewer obstructions 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 are fewer external obstructions.

[0012] In a possible implementation, the shell of the second earphone body is provided with a first connecting hole, the first connecting hole and the first sound pickup hole are spaced apart, and the first connecting hole is used to allow the end of the connecting arm to extend into the interior of the second earphone body.

[0013] Along the first direction, the projection of the center of the first pickup hole on the symmetry plane is the first projection, the projection of the center of the first connecting 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 earphone body is A2.

[0014] The relationship between A1 and A2 satisfies:

[0015] It is understandable that when the user wears the earphone, the second earphone body is located outside the user's ear and away from the first earphone body. 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 and the connecting arm is smaller than the distance between the first sound pickup hole and the user's skin. The first sound pickup hole has less obstruction around it. When the microphone in the second earphone body picks up sound through the first sound pickup hole, it is less obstructed by the outside.

[0016] In a possible implementation, the second earphone 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 external sound of the second earphone body through the first sound pickup hole, and the second feedforward microphone picks up external sound of the second earphone body through the second sound pickup hole. The first feedforward microphone and the second feedforward microphone are symmetrical about the symmetry plane.

[0017] It is understandable that the first feedforward microphone and the second feedforward microphone can be used for active noise cancellation of the headset. Active noise cancellation is a method of identifying unwanted sound sources as noise, and eliminating the original noise by generating an "anti-noise" signal, thereby eliminating the noise in real time. When the user uses the headset, the noise heard from the headset is less, and the user experience is better. The first feedforward microphone and the second feedforward microphone are symmetrically arranged about the symmetry plane. Regardless of whether the user wears the headset on the right ear or the left ear, the noise information received by the first feedforward microphone and the second feedforward microphone when picking up the noise is not much different, and the active noise cancellation effect of the headset is basically the same. In this way, when the user uses the headset, regardless of whether the user wears the headset on the right ear or the left ear, the sound output effect of the headset is basically the same.

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

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

[0020] In a possible implementation, the second earphone body includes a first bracket, the first bracket is fixed to the inside of the shell of the second earphone body, the first feedforward microphone is fixed on the first bracket, and the first pipe is located on the first bracket.

[0021] It is understandable that, compared with the solution in which the first pipe is directly arranged on the shell of the second earphone body, the first pipe is arranged on the first bracket, which is conducive to reducing the difficulty of molding the shell of the second earphone body and facilitating the replacement and maintenance of the internal components of the second earphone body. The first bracket can be used to carry the first feedforward microphone, and the first feedforward microphone can be assembled to the first bracket first, and then assembled as a whole into the shell of the second earphone body, which is conducive to the assembly of the second earphone body.

[0022] In a possible implementation, the first earphone body includes a housing and a first capacitance sensor, the first capacitance sensor is arranged inside the housing of the first earphone body, the second earphone body includes a second capacitance sensor and a controller, the second capacitance sensor and the controller are both arranged inside the housing of the second earphone body, and the first capacitance sensor and the second capacitance sensor are electrically connected to the controller. The first capacitance sensor is used to obtain a first capacitance value in a first environment, the second capacitance sensor is used to obtain a second capacitance value in a second environment, and the controller is used to determine whether the user is wearing 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, the present application sets the first capacitive sensor on the first earphone body and the second capacitive sensor on the second earphone 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, the outer surface of the first earphone is symmetrical about the symmetry plane;

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

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

[0027] It is understandable that the outer surfaces of the first earphone body, the flexible connecting arm and the second earphone body are completely symmetrical about the symmetry plane, so the earphone originally set for the left ear can be worn on the right ear after being turned over. Therefore, when wearing the earphone provided by the present application, the user does not need to distinguish the left and right ears in appearance.

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

[0029] It is understandable that when the user wears the headset 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 with, while the parasitic unit is located farther away from the user, with less blockage and the signal is not easily interfered with. When the user wears the headset on the right ear, the parasitic unit is close to the user's skin, and the main unit is located farther away from the user. In this way, whether the user wears the headset on the left or right ear, the interference to the signal of the antenna module is similar, and the sensitivity of the headset to play sound or receive signals is also similar, and the user experience is better.

[0030] In a possible implementation, the second earphone 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 earphone body, the first electrode and the second electrode are both electrically connected to the battery, and 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 symmetrical about a symmetric 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 earphone body, and the first electrode and the second electrode are symmetrical about the symmetric 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 shell of the second earphone body, and the first electrode and the second electrode are symmetrical about the symmetry plane. Regardless of whether the user wears the earphone on the left ear or the right ear, the appearance of the first electrode and the second electrode on the shell of the second earphone body is the same, and the user has a better experience when wearing the earphone.

[0032] In a possible implementation, the first earphone body includes an outer shell and a speaker, the speaker is fixedly connected to the inner surface of the outer shell of the first earphone body, the speaker and the inner surface of the outer shell of the first earphone body enclose a first sub-cavity, the speaker and the inner surface of the outer shell of the first earphone body enclose a second sub-cavity, and the sound output surface of the speaker faces the first sub-cavity. The outer surface of the first earphone body is symmetrical about the symmetry plane, the outer shell of the first earphone body is provided with two pressure relief holes, the pressure relief holes are connected to the second sub-cavity and the outside of the first earphone body, and the two pressure relief holes are arranged at intervals and are symmetrical about the symmetry plane.

[0033] It can be understood that compared with the method of setting only 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 symmetrical about the symmetry plane, and one of the two pressure relief holes is always kept facing the ground and the other facing the side away from the ground to ensure the pressure relief effect. Users do not need to distinguish between left and right ears when wearing earphones. In addition, when sweat blocks one of the pressure relief holes, there is another pressure relief hole that can work to balance the air pressure in the second sub-cavity.

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

[0035] It is understandable that the bone vibration sensor can be used to pick up vibrations when the user speaks, thereby facilitating call noise reduction.

[0036] In a possible implementation, along the length direction of the connecting arm, the connecting arm has a first end and a second end spaced apart, the first end is connected to the first earphone body, and the second end is connected to the second earphone body. The central axis direction of the first end and the central axis direction of the second end are arranged at an angle, and the angle ranges from 11.4° to 26°.

[0037] It can be understood that, compared with the solution in which the central axis direction of the first end of the connecting arm 300 and the central axis direction of the second end of the connecting arm are set in parallel, the first end and the second end of the connecting arm are set at an angle in the range of 11.4° to 26°. When the user wears the earphone 0, the relative positions of the first earphone body and the second earphone body can better fit the inclination angle and contour curve of the user's ear, effectively reducing the sense of oppression of the first earphone body and the second earphone body of the earphone 0 on the earphone, and the user's experience is better.

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

[0039] It is understandable that when the connecting arm is bent, the deformation degree of the wire harness can be smaller than the deformation degree of the tube body. In other words, when the connecting arm is bent, the stretching amount of the wire harness is smaller than the stretching amount of the tube body. In this way, the wire harness is not easy to be 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 power supply. The second signal line is a signal transmission channel for a 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 assembled together 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 wires 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 of the connecting arm connecting 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, and the earphone is disposed in the earphone case. Description of the Drawings

[0093] The embodiments of the present application are described below in conjunction with the 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 two are connected to each other and the relative position relationship after the connection remains unchanged. It should be understood that when component A is fixedly connected to component C through component B, changes in the relative position relationship caused by the deformation of component A, component B and component C itself are allowed. Among them, the two components are integrated into an integrated structure through an integrated molding process, which means that in the process of forming one of the two components, the component is connected to the other component, and there is no need to connect the two components together through reprocessing (such as bonding, welding, snap connection, screw connection).

[0095] The directional terms mentioned in the embodiments of the present application, such as "upper", "lower", "side", etc., are only references to the directions of the drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.

[0096] The term "plurality" means at least two. The term "above" includes the number itself. The term "and / or" is a description of an association relationship between associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The terms "first", "second", etc. are used only for descriptive purposes and cannot be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0097] The present application provides an earphone 1000 and a pair of earphones, wherein the earphone 1000 is a clip-on wireless earphone (True Wireless Stereo, TWS) that can be clamped on the ear. Clip-on earphones can reduce ear discomfort of the wearer and improve 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 to be worn on the left ear and the right ear of the user. The first earphone and the second earphone do not distinguish between 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, the portability of the earphone 1000 is improved.

[0098] In some embodiments, the earphone 1000 may be an open earphone, so that the earphone does not need to penetrate into the ear canal of the user's ear, which can reduce ear canal allergies and damage, and the user can sense changes in the surrounding environment at any time, reducing the risk of accidents.

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

[0100] like Figure 1 and Figure 2As shown, the earphone 1000 is roughly U-shaped, and includes a first earphone body 100, a second earphone body 200, and a connecting arm 300. The connecting arm 300 is roughly U-shaped and connected between the first earphone body 100 and the second earphone body 200. The first earphone body 100 is electrically connected to the second earphone body 200. Exemplarily, along the length direction of the connecting arm 300, the connecting arm 300 has a first end and a second end that are arranged opposite to each other, the first end is connected to the first earphone body 100, and the second end is connected to the second earphone body 200. In this way, the first earphone body 100 and the second earphone body 200 can be physically connected through the connecting arm 300. In addition, the first earphone body 100 and the second earphone body 200 can also be electrically connected through the connecting arm 300. For example, the connecting arm 300 may include a wiring harness, one end of the wiring harness is electrically connected to the first earphone body 100, and the other end of the wiring harness can be electrically connected to the second earphone body 200.

[0101] For the convenience of description, the geometric center of the outer surface of the first earphone body 100, the geometric center of the outer surface of the second earphone body 200 and the geometric center of the outer surface of the connecting arm 300 define a unique plane, which is the 0-0 plane ( Figure 1 For ease of description, the direction perpendicular to the 0-0 plane is defined as the Z axis, the direction from the end of the connecting arm 300 connected to the second earphone body 200 pointing to the center of the second earphone body 200 is defined as the X axis, and the direction perpendicular to the X axis and the Z axis is defined as the Y axis.

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

[0103] Figure 3 This is a state diagram of an implementation mode of a user using the earphone 1000 provided by the present application.

[0104] like Figure 3 As shown, the first earphone body 100 can be used for sound production. When the user uses the earphone, the first earphone body 100 can be clamped in the user's concha cavity, and does not penetrate 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, so the earphone 1000 provided in the present application can greatly improve the wearing comfort compared to in-ear audio devices.

[0105] 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. It can be understood that the connecting arm 300, the first earphone body 100, and the second earphone body 200 clamp the user's auricle together, so that the earphone 1000 is worn on the ear.

[0106] In some embodiments, the connecting arm 300 may have a deformable ability and may be used to adjust the distance between the first earphone body 100 and the second earphone body 200, so that the distance between the first earphone body 100 and the second earphone body 200 is adjusted from the initial distance to the adjusted distance. The initial distance refers to the distance between the first earphone body 100 and the second earphone 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. The initial distance and the adjusted distance both refer to the distance between the first earphone body 100 and the second earphone body 200; the distance between the surfaces of the first earphone body 100 and the second earphone body 200 facing each other, that is, the distance between the two earphone 1000 surfaces that first contact the ear.

[0107] It is understandable that the earphone 1000 equipped with the deformable connecting arm 300 can adapt to users with different ear thicknesses, provide appropriate clamping force for each user, and avoid clamping too tight or too loose to affect the wearing experience. At the same time, when the user puts on and takes off the earphone 1000 provided by the present application, the connecting arm 300 can be used to increase the distance between the first earphone body 100 and the second earphone body 200 to ensure that the earphone 1000 is smoothly put on and taken off, avoid the ear being deformed by pressure, and improve the user's experience when putting on and taking off the earphone 1000.

[0108] When the user uses the earphone, the first earphone body 100 can be used to make a sound. For example, the first earphone body 100 may include a speaker, and the sound is produced by the speaker. The first earphone body 100 can be clamped in the user's concha cavity, and 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 earphone body 200 can be used to pick up the external noise of the second earphone 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, thereby eliminating the noise in real time. When the user uses the earphone 1000, the noise in the sound emitted by the earphone 1000 is small, and the user experience is better. An embodiment of the second earphone body 200 will be specifically described below through the accompanying 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 included angle between any two of the first symmetry plane, the second symmetry plane, and the third symmetry plane, and the included angle is less than or equal to 1°. For example, the included 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 included angle between the first symmetry plane and the second symmetry plane can be less than 1°, or the included angle between the first symmetry plane and the third symmetry plane can be less than 1°, or the included 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 diagram of the second ear body 200 shown in another angle.

[0112] As Figure 2 and Figure 4 shown, the length D1 of the outer shell 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 (i.e., the second end) where the connecting arm 300 is connected to the second ear body 200 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 outer shell 209 of the second ear body 200 in the first direction. There can be many lines connecting the outer shell 209 of the second ear body 200 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 earphone body 200 may include a short axis L2. The short axis L2 is the length of the two farthest endpoints of the second earphone body 200 in the second direction. The housing 209 of the second earphone 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 minor axis L2 is in the range of 11.44 mm to 13.44 mm. For example, the length D2 of the minor axis L2 may be 11.44 mm, 12.44 mm, or 13.44 mm.

[0117] In some embodiments, the length of the housing 209 of the second earphone body 200 in the second direction is shorter than the length in the first direction. The length of the housing 209 of the second earphone body 200 in the third direction is shorter than the length in the first direction, and the third direction and the second direction are different from the first direction. Figure 2 The third direction is shown as the Y-axis direction. In other embodiments, the third direction may also be any direction in the XY plane, for example, a direction that forms a certain angle with the Y-axis. In this way, the second earphone body 200 may be roughly ellipsoidal, and when the user wears the earphone 1000, the longer direction of the ellipsoid is roughly the same as the length direction of the ear.

[0118] In some embodiments, the shell 209 of the second earphone body 200 may be in the shape of a "broad bean". It is understandable that the second earphone body 200 adopts a prosthetic design and is in the shape of a broad bean, which fits the curved surface of the user's auricle when worn, thereby improving the wearing comfort of the user. When the user wears the earphone 1000, the first direction is substantially the same as the length direction of the ear.

[0119] Figure 5 yes Figure 4 An exploded schematic diagram of an embodiment of the second earphone body 200 is shown in FIG. Figure 6 yes Figure 4 FIG. 1 is a partial cross-sectional view of an embodiment of the second earphone body 200 at the section line AA shown in FIG.

[0120] like Figure 5 and Figure 6As shown, the second earphone body 200 may include a housing 209, an antenna module 230, a battery 240, a mainboard bracket 250, a mainboard 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. The antenna module 230, the battery 240, the mainboard bracket 250, the mainboard 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 earphone body 200.

[0121] Exemplarily, the housing 209 of the second earphone 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 the second space 201. The antenna module 230, the battery 240, the mainboard bracket 250, the mainboard 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 in the second space 201.

[0122] like Figure 6 As shown, the third housing 210 may have an outer surface 211, an inner surface 212, and a third end surface 213. 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 surface 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 surface 223. 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 surface 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 surface 213 of the third housing 210 is connected to the fourth end surface 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 earphone 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 earphone 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 symmetrical about the second symmetric plane. The fourth housing 220 may also be symmetrical about the second symmetric plane. Thus, the outer surface 211 of the third housing 210 and the outer surface 221 of the fourth housing 220 may constitute the outer surface of the second earphone body 200 and may also be symmetrical about the second symmetric plane.

[0125] Figure 7 yes Figure 5 A structural schematic diagram of an implementation manner of the third housing 210 is shown in FIG.

[0126] like Figure 7 As 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 connects the outer surface 211 and the inner surface 212 of the third housing 210. The second sound pickup hole 215 can connect 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 along the first direction. In some embodiments, the first sound pickup hole 214 and the second sound pickup hole 215 may be symmetrical about the second symmetry plane.

[0128] The third housing 210 is provided with a first charging hole 216 and a second charging hole 217 arranged at intervals. The first charging hole 216, the second charging hole 217, the first sound pickup hole 214, and the second sound pickup hole 215 are arranged at intervals. The first charging hole 216 can connect the outer surface 211 and the inner surface 212 of the third housing 210. The second charging hole 217 can connect the outer surface 211 and the inner surface 212 of the third housing 210.

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

[0130] In some embodiments, the first charging hole 216 and the second charging hole 217 may be symmetrical about a symmetry plane (ie, 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 connects 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 along the first direction and located on both sides of the first connection hole 218 . Figure 8 yes Figure 5 Schematic diagram of assembly of an antenna module 230 and a third housing 210 according to an embodiment of the present invention.

[0133] like Figure 8As shown, the antenna module 230 may be fixedly connected to the inner surface 212 of the third housing 210. For example, the antenna module 230 may be fixedly connected to the inner surface 212 of the third housing 210 by gluing, welding, or the like.

[0134] In some embodiments, the inner surface 212 of the third housing 210 may be provided with a first positioning column 2121. The first positioning column 2121 may be formed by a protrusion of the inner surface 212. At the same time, the antenna module 230 may be provided with a positioning hole 233. When the antenna module 230 is installed to the third housing 210, the first positioning column 2121 is at least partially located in the positioning hole 233. It can be understood that by providing the first positioning column 2121 and the positioning hole 233, during the assembly process of the antenna module 230, it can help to quickly locate, and at the same time, in the subsequent assembly process, it can also prevent the antenna module 230 from being displaced.

[0135] In some embodiments, the antenna module 230 may be symmetrical about a symmetry plane 0-0.

[0136] Fig. 9 yes Figure 8 Schematic diagram of an exploded view of an embodiment of the antenna module 230 shown in FIG.

[0137] like Fig. 9 As shown, the antenna module 230 may 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 to protect and insulate the antenna structure 232. The antenna structure 232 may be used to transmit and receive antenna signals.

[0138] In some embodiments, the antenna structure 232 may be symmetrical about the symmetry plane 0-0. In this way, no matter whether the user wears the headset 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 headset 1000 in playing sound or receiving signals is relatively similar, so that the user has a better experience.

[0139] In some embodiments, the antenna module 230 may use a monopole antenna with a parasitic unit. Exemplarily, the antenna structure 232 includes a main unit 2311, a parasitic unit 2312, a ground trace 2313, and a feed trace 2314. The main unit 2311 and the parasitic unit 2312 are spaced and insulated. One end of the feed trace 2314 is connected to the main unit 2311, and the other end is connected to the main board 250 (not shown). The feed trace 2314 is used to supply power to the main 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). The ground trace 2313 is used to ground the parasitic unit 2312. Among them, the main unit 2311 is a monopole antenna. The parasitic unit 2312 serves as a parasitic unit. During the operation of the antenna module 230, the main board 250 (not shown) can supply power to the main unit 2311 through the feeding line 2314 to stimulate the main unit 2311 to work. After the main unit 2311 is powered on, the parasitic unit 2312 is coupled and excited, and a capacitive coupling excitation parasitic mode can be formed between the main 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 unit 2311 and the parasitic unit 2312 can be symmetrical about the symmetry plane 0-0. It is understandable that during the operation of the antenna module 230, when the main unit 2311 of the antenna structure 232 is close to the user's skin, it is more blocked and the signal is easily interfered with, while the parasitic unit 2312 is located at a position farther away from the user, with less blockage, and the signal is not easily interfered with. Vice versa, when the parasitic unit 2312 is close to the user's skin, the main unit 2311 is located at a position farther away from the user. In this way, no matter whether the user wears the headset 1000 on the left ear or the right ear, the interference to the signal of the antenna module 230 is similar, and the sensitivity of the headset 1000 to play sound or receive signals is also relatively similar, and the user experience is better.

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

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

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

[0144] Fig.10 yes Figure 5 A schematic diagram of the partial structural assembly of the second earphone body 200 is shown in FIG. Fig.11 yes Fig.10 A cross-sectional view of one embodiment of the structure shown in FIG. 1 at section line BB.

[0145] like Fig.10 and Fig.11 As shown, the battery 240 may be disposed on a side of the antenna module 230 away from the third housing 210. The battery 240 may be fixedly connected to the inner surface 212 of the third housing 210. For example, the battery 240 may be fixedly connected to the inner surface 212 of the third housing 210 by gluing.

[0146] In some embodiments, the battery 240 and the antenna module 230 are disposed opposite and spaced apart along the Y-axis direction. For example, along the Y-axis direction, the distance between the battery 240 and the antenna module 230 may be greater than or equal to 0.2 mm, for example, the distance between the battery 240 and the antenna module 230 may 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 arranged at intervals on both sides of the battery 240. The first bracket 271 and the second bracket 272 are arranged at intervals 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 gluing. The first feedforward microphone 273 is fixedly connected to the first bracket 271. The first feedforward microphone 273 and the battery 240 and the antenna module 230 are arranged at intervals. The second feedforward microphone 274 is fixedly connected to the second bracket 272. The first feedforward microphone 273 and the battery 240 and the antenna module 230 are arranged at intervals. 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 reduction, picking up the ambient sound (i.e., the noise outside the ear) near the second earphone body 200, and outputting the reverse phase sound to cancel the ambient sound. Exemplarily, the first feedforward microphone 273 can be fixedly connected to the side of the first bracket 271 away from the battery 240. The second feedforward microphone 274 can be fixedly connected to the 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 arranged at intervals along the Z-axis direction.

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

[0149] In some implementations, the first feed-forward microphone 273 and the second feed-forward microphone 274 may be symmetrical about the 0-0 plane.

[0150] Fig.12 yes Figure 5 Schematic diagram of an assembly of a first feedforward microphone 273, a second feedforward microphone 274, a first bracket 271, a second bracket 272 and a second circuit board 280 in one embodiment shown in FIG. Fig.13 yes Fig.12 A partial cross-sectional view of one embodiment of the structure shown in FIG. 1 at section line CC.

[0151] like Fig.12 and Fig.13 As shown, the first feedforward microphone 273 and the second feedforward microphone 274 are connected to the second circuit board 280, and are 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 arranged between the first feedforward microphone 273 and the first bracket 271. The first bracket 271 can also be used to carry the 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 arranged between the second feedforward microphone 274 and the second bracket 272. The second bracket 272 can also be used to carry the part of the second circuit board 280 connected between the second feedforward microphone 274 and the second bracket 272.

[0152] Fig.14 yes Fig.10 A partial cross-sectional view of an embodiment of the structure shown in FIG. 1 at section line DD.

[0153] like Fig.14 As shown, the second earphone body 200 may be provided with a first pipe 2711, the first pipe 2711 is located inside the shell of the second earphone body 200, the first pipe 2711 is connected to the first sound pickup hole 214, and the sound pickup surface of the first feedforward microphone 273 is arranged opposite to the first pipe 2711. The second earphone body 200 may be provided with a second pipe 2721, the second pipe 2721 is located inside the shell 209 of the second earphone body 200, the second pipe 2721 is connected to the second sound pickup hole 215, and the sound pickup surface of the second feedforward microphone 274 is arranged opposite to the second pipe 2721.

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

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

[0156] In other embodiments, the second earphone body 200 may not be provided with the first bracket 271 and the second bracket 272. In this case, the sound pickup surface of the first feedforward microphone 273 and the first sound pickup hole 214 are arranged opposite to each other, and the sound pickup surface of the second feedforward microphone 274 and the second sound pickup hole 215 are arranged opposite to each other. The first feedforward microphone 273 picks up external noise of the second earphone body 200 through the first sound pickup hole 214. The second feedforward microphone 274 picks up external noise of the second earphone 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 along 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 implementations, the first sound pickup hole 214 and the second sound pickup hole 215 may also be symmetrical about the 0-0 plane of the earphone 1000 .

[0159] It can be understood that, compared with the solution of only providing one of the first sound pickup hole 214 or the second sound pickup hole 215, the first sound pickup hole 214 and the second sound pickup hole 215 are symmetrical about the 0-0 plane. No matter whether the user wears the headset 1000 on the left ear or the right ear, the first sound pickup hole 214 and the second sound pickup hole 215 can be guaranteed to always have one side located away from the skin. In this way, it can be ensured that the user does not distinguish between the left and right ears. When the headset 1000 is working, the first feedforward microphone 273 or the second feedforward microphone 274, which is located on the side away from the user's skin, can better pick up the ambient noise, and the active noise reduction effect is better. In addition, no matter whether the user wears the headset 1000 on the left ear or the right ear, the first sound pickup hole 214 and the second sound pickup hole 215 can always keep one of them facing the ground and the other facing the side away from the ground. When the sound pickup hole facing the side away from the ground is blocked by sweat dripping into it, 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 symmetrical about the 0-0 plane of the earphone 1000, the center of the first sound pickup hole 214 and the center of the second sound pickup hole may be symmetrical 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 may partially overlap.

[0161] In some embodiments, a line connecting the center of the first sound pickup hole 214 and the center of the second sound pickup hole 215 may form an angle with the 0-0 plane, and the angle may be in a 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 a first projection, the projection of the center of the second sound pickup hole on the symmetry plane is a third projection, and the first projection and the third projection coincide with each other.

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

[0164] Two working modes of the first feedforward microphone 273 and the second feedforward microphone 274 for active noise reduction are described below:

[0165] (1) During the active noise reduction operation of the earphone 1000, the first feedforward microphone 273 and the second feedforward microphone 274 can work simultaneously to pick up the sounds near the first sound pickup hole 214 and the second sound pickup hole 215, and the two channels of data are fused through an algorithm to 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 Fig.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 vent hole 281, and the first vent hole 281 is connected to the first pipe 2711. In this way, the sound near the first sound pickup hole 214 can pass through the first pipe 2711 and the first vent 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). The second ventilation hole is connected to the second pipe 2721 .

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

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

[0176] like Fig.13 As shown, the first pipe 2711 may be curved, that is, the first pipe 2711 may include a curved pipe. Exemplarily, the first pipe 2711 may include a first section 2712 and a second section 2713, the first section 2712 is connected to the second section 2713, and the first section 2712 is connected to an end of the second section 2713 away from the first feedforward microphone 273. The central axis L3 ( Fig.13 The middle axis L4 ( Fig.13 The first pipeline 2711 may be in an "L" shape or a "V" shape as a whole.

[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 a single 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 disposed 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 disposed 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 disposed on the connecting arm 300, and the sound pickup hole can also be disposed 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 also be provided with a first microphone (not shown in the figure) and a second microphone (not shown in the figure) for calls. The first microphone and the second microphone can be used to pick up the user's speaking voice. The first microphone can pick up the user's speaking voice through the first sound pickup hole 214. The second microphone can pick up the user's speaking voice through the second sound pickup hole 215. Exemplarily, the setting manner of the first microphone can refer to the setting manner of the first feedforward microphone. The setting manner of the second microphone can refer to the setting manner of the second feedforward microphone.

[0184] As Fig.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, which is not limited in this application.

[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 the positive electrode and the negative electrode of the battery 240 respectively. This 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 can be electrically connected to the second circuit board 280. The battery 240 can be electrically connected to the second circuit board 280. The second circuit board 280 can also be used for 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 symmetrical about the 0-0 plane, so as to facilitate the symmetrical distribution of the weight of the second earphone body 200 about the 0-0 plane.

[0190] like Fig.14 As shown, the second earphone body 200 may further include a second magnet 299. The second magnet 299 may be disposed in the second space 201 of the second earphone body 200 and fixedly connected to the third housing 210. The second magnet 299 may be used to assist the earphone 1000 in quickly positioning when the earphone 1000 is charged in the paired earphone 1000 compartment. 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 symmetrical 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 be one, or three or more.

[0194] Fig.15 yes Figure 5 A structural schematic diagram of an embodiment of a mainboard bracket 250 is shown in FIG.

[0195] like Fig.15 As shown, the mainboard bracket 250 may include a main body 251, an extension 252, a first limiting portion 253 and a second limiting portion 254. The main body 251 may be annular. The main body 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 disposed opposite to each other, and the inner side face 2513 and the outer side face 2514 are disposed opposite to each other. 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 a receiving space 255. The outer side face 2514 is connected between the first end face 2511 and the second end face 2512. The extension 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 surface 2513 of the main body 251 and are arranged at intervals. 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 mainboard bracket 250 may further include a second positioning column 256. The second positioning column 256 may be fixedly connected to the second end surface 2512 of the main body 251. The number of the second positioning column 256 may be one or more. When the number of the second positioning column 256 is more than one, the plurality of second positioning columns 256 are spaced apart from each other.

[0197] Fig.16 yes Figure 5 FIG. 2 is a schematic diagram of an assembly of a circuit board 261 and a mainboard bracket 250 according to an embodiment of the present invention. Fig.17 yes Fig.16 A schematic diagram of the structure shown in FIG. 1 at another angle.

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

[0199] The circuit board 261 can be fixedly connected to the second end surface 2512 of the mainboard bracket 250. Exemplarily, the circuit board 261 may include a first surface 2611 and a second surface 2612 that are disposed opposite to each other. The first surface 2611 is fixedly connected to the second end surface 2512 of the mainboard bracket 250. The electronic device 262 can be disposed on the first surface 2611 or on the second surface 2612. That is, both sides of the circuit board 261 can be used to set the electronic device 262, and those skilled in the art can set it as needed.

[0200] In some embodiments, the electronic device 262 may include an accelerometer 2621 (ACC). The accelerometer 2621 may be fixedly connected to the second surface 2612 of the circuit board 261. The accelerometer 2621 may be used to measure the acceleration of the second earphone body 200, thereby determining the spatial position of the second earphone body 200. In other words, the motion state of the second earphone body 200 in space may 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 may be used to achieve electrical connection between the circuit board 261 and other signal transmission structures. Exemplarily, the mainboard 260 may include a board to board connector (BTB), which is fixedly connected to the second side 2612 of the circuit board 261.

[0202] In some implementations, the electronic device 262 may further include a main chip 2623. The main chip 2623 may be used to control functions of the headset 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 (eg Fig.16 ), when the circuit board 261 can be fixedly connected to the mainboard bracket 250, the second positioning column 256 can be located in the avoidance hole 2613. It can be understood that by providing the avoidance hole 2613 and the second positioning column 256, the avoidance hole 2613 and the second positioning column 256 cooperate with each other, which can help to quickly locate the circuit board 261 during the assembly process, and can also prevent the circuit board 261 from displacement in the subsequent assembly process.

[0204] Fig.18 yes Figure 5 A schematic diagram of the partial structural assembly of the second earphone body 200 is shown in FIG. Fig.19 yes Fig.18 FIG. 2 is a cross-sectional view of an embodiment of the second earphone body 200 at the section line EE shown in FIG.

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

[0206] Exemplarily, the third housing 210 may have a boss 219. The boss 219 may be formed by a protrusion of the inner surface 212 of the third housing 210. The extension 252 of the mainboard bracket 250 may be fixedly connected to the boss 219. In the direction from the third housing 210 to the fourth housing 220, the projection of the extension 252 on the boss 219 at least partially overlaps with the boss 219. The mainboard bracket 250 may be used to support the mainboard 260, and may also be used to prevent the mainboard 260 from shaking under the action of external force, causing interference with the operation of the mainboard 260, and interference with other devices inside the second earphone body 200.

[0207] In some embodiments, the mainboard 260 and the battery 240 are stacked in the Y-axis direction. For example, the mainboard 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 in the second accommodation space 2517. Part of the main body 251, the first limiting portion 253, and the second limiting portion 254 of the mainboard bracket 250 are arranged around the battery 240. In this way, the battery 240 can be further limited, reducing the risk of displacement of the battery 240 in the XZ direction.

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

[0210] The second circuit board 280 is connected to the main board 260 and is electrically connected to the main board 260. For example, the second circuit board 280 is connected to the electrical connector 2622 ( Fig.16 The electrical connector 2622 is schematically shown in the figure), thereby realizing electrical connection with the main board 260. It is understandable that the battery 240 can be electrically connected to the main board 260 through a flexible circuit board or a conductive trace. When the user charges the headset 1000, the current can 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 realize electrical connection between the first feedforward microphone 273 and the second feedforward microphone 274 and the main board 250.

[0211] Fig. 20 yes Fig.18 FIG. 4 is a cross-sectional view of an embodiment of the second earphone body 200 at the section line FF shown in FIG.

[0212] like Fig. 20 As shown, along the Y-axis direction, there is a gap between the projection of the mainboard 260 to the plane where the mainboard bracket 250 is located and the mainboard bracket 250. That is, a first gap 266 can be enclosed between the mainboard bracket 250 and the mainboard 260. The first gap 266 can be used to arrange the wiring. Exemplarily, the feed line 2314 of the antenna module 230 can be connected to the mainboard 260 through the gap between the third housing 210 and the battery 240 and the first gap 266, thereby realizing the power supply of the antenna module 230. It can be understood that by setting the first gap 266, it can 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 mainboard 260.

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

[0214] Fig.21 yes Figure 5 A schematic diagram of the partial structural assembly of the second earphone body 200 is shown in FIG. Fig. 22 yes Fig.21 0 is a cross-sectional view of one embodiment of the structure shown in FIG. 1 at section line GG.

[0215] like Fig.21 and Fig. 22 As shown, the second capacitive sensor 290 can be arranged on a side of the mainboard 260 away from the battery 240. The second capacitive sensor 290 can be arranged at intervals from the first feedforward microphone 273 and the second feedforward microphone 274. The second capacitive sensor 290 can be connected to the mainboard 260 and electrically connected to the mainboard 260. Exemplarily, the second capacitive sensor 290 can be electrically connected to the mainboard 260 through a flexible circuit board. In some embodiments, the second capacitive sensor 290 can also be called a proximity sensor, which can be used to detect whether the user is wearing the headset 1000. When the second capacitive sensor 290 is close to the user's skin, the capacitance of the second capacitive sensor 290 changes, generating an electrical signal, and the distance between the second capacitive sensor 290 and the user can be judged based on the change in the electrical signal.

[0216] In some implementations, along the Y-axis direction, the antenna module 230 , the battery 240 , the mainboard 260 , and the second capacitive sensor 290 may be stacked.

[0217] Fig.23 yes Figure 1 FIG. 1 is a schematic structural diagram of the earphone 1000 at another angle.

[0218] like Fig.23 As shown, the first sound pickup hole 214 and the second sound pickup hole 215 can be arranged at intervals along the first direction and located on both sides of the first connecting hole 218. The first connecting hole 218 can be used to allow the end of the connecting arm 300 to extend into the second earphone body 200. That is, the first sound pickup hole 214 and the second sound pickup hole 215 can 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 one side of the long axis L1 close to the connecting arm 300.

[0219] In the present application, an earphone 1000 is specifically introduced in combination with relevant drawings. The earphone 1000 includes a first earphone body 100, a connecting arm 300 and a second earphone body 200. The connecting arm 300 is connected between the first earphone body 100 and the second earphone body 200. The first earphone body 100 is used for sound generation. The second earphone body 200 is used for picking up noise. The second earphone body 200 includes a shell and a first feedforward microphone 273. The first feedforward microphone 273 is arranged inside the shell of the second earphone body 200. The shell 209 of the second earphone body 200 is provided with a first sound pickup hole 214, and the first feedforward microphone 273 picks up external noise of the second earphone body 200 through the first sound pickup hole 214. The length of the shell 209 of the second earphone body 200 in the first direction is greater than the length in the second direction. The second earphone body 200 includes a long axis, which is a line connecting the two farthest end points of the shell 209 of the second earphone body 200 in the first direction. The first pickup hole 214 is located on the side of the long axis close to the connecting arm 300. The second direction is different from the first direction, and the second direction is the direction in which the end of the connecting arm 300 connected to the second earphone body 200 points to the center of the second earphone body 200.

[0220] It can be understood that, compared with the solution in which the long axis L1 passes through the first sound pickup hole 214, the first sound pickup hole 214 is arranged on the side of the long axis L1 close to the connecting arm 300. 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 active noise reduction effect.

[0221] Several implementations of the first earphone body 100 will be described in detail below with reference to the accompanying drawings. Fig.24 yes Figure 1 A structural schematic diagram of an implementation manner of the first earphone body 100 is shown in FIG. Fig.25 yes Fig.24 A partial structural exploded schematic diagram of the first earphone body 100 is shown in FIG.

[0222] like Fig.24 and Fig.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] Fig.26 is Fig.24 A partial cross-sectional view of an embodiment of the first ear body 100 shown in the sectional line H-H.

[0227] As Fig.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 surface 13 of the first housing 10 is connected to the second end surface 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 constitute 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 constitute 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 may be fixedly connected by gluing or snapping.

[0231] like Fig.26 As 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 outlet 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 connects the external space of the first earphone body 100 (that is, the environment in which 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 arranged opposite to the speaker 30.

[0232] In some embodiments, the first housing 10 may have a first boss 15. The first boss 15 may be located in the first sub-cavity 102. The first boss 15 may be formed by the inner surface 12 of the first housing 10 protruding 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 may be fixedly connected to the first boss 15. Exemplarily, the first boss 15 may 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 arranged at intervals. The first sub-cavity 102 can be used as a 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 a 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 connect the second sub-cavity 103 with the external space of the first earphone body 100 (that is, the environment where the first earphone body 100 is located) to balance the air pressure of the second sub-cavity 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 symmetrical about the 0-0 plane. It is understandable that the two pressure relief holes 24 are symmetrically arranged so that when the user uses the earphone 1000, there is no need to distinguish between the left and right ears. At the same time, the two pressure relief holes 24 are symmetrically distributed. When the earphone 1000 is worn, if sweat blocks one of the pressure relief holes 24, the other pressure relief hole 24 can work to balance the air pressure in the second sub-cavity 103.

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

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

[0237] In some embodiments, the line connecting the first through hole 14 and the pressure relief hole 24 is the first line, and the line connecting the second connection hole 26 and the first through hole 14 is the second line. The first line and the second line form an angle. When the speaker 30 makes a sound, the sound leakage on the first line is greater than the sound leakage on the second line. The first through hole 14 can form a dipole sound field with the pressure relief hole 24. Exemplarily, when the user wears the earphone 1000, the second connection hole 26 faces the front side of the user, and the two pressure relief holes 24 are arranged on both sides of the second connection hole 26, which can reduce the sound leakage on the front side of the user.

[0238] like Fig.26 As shown, the speaker 30 can be fixed at the section with the largest diameter of the first housing 10. In other embodiments, the speaker 30 can also be fixedly connected to the inner surface 22 of the second housing 20 and fixedly connected to the section with the largest diameter of the second housing 20.

[0239] In some embodiments, the speaker 30 is a dual-magnetic diaphragm speaker. Compared with a traditional dynamic iron speaker, the speaker 30 is a dual-magnetic diaphragm speaker, which 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 a certain distance away from the ear canal.

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

[0241] Exemplarily, the dustproof net 90 may include a main body 91 and two connecting parts 92. The connecting part 92 is connected to the main body 91. The two connecting parts 92 are arranged at intervals. The first housing 10 is provided with a second through hole 16 and a third through hole 17 arranged at intervals. The second through hole 16 and the third through hole 17 surround the first through hole 14. The two connecting parts 92 are respectively connected to the second through hole 16 and the third through hole 17. The main body 91 is a mesh structure, covering the first through hole 14.

[0242] In some embodiments, the first earphone body 100 may further include a first waterproof breathable membrane 93. The first waterproof breathable membrane 93 may be connected to the first housing 10 and cover the first through hole 14. Exemplarily, the first waterproof breathable membrane 93 may be disposed between the main body 91 of the dustproof net 90 and the first housing 10. It is understandable that by providing the first waterproof breathable membrane 93, the first sub-cavity 102 and the external space of the first earphone body 100 are connected, the air pressure in the first sub-cavity 102 is balanced, and at the same time, external dust and water vapor can be prevented from entering the first sub-cavity 102 through the first through hole 14, thereby avoiding affecting the operation of the speaker 30.

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

[0244] In some embodiments, the first earphone body 100 may further include a second waterproof breathable membrane 94. The second waterproof breathable membrane 94 is connected to the inner surface 22 of the second housing 20 and covers the pressure relief hole 24. It is understandable that by providing the second waterproof breathable membrane 94, the second sub-cavity 103 and the external space of the first earphone body 100 are connected, the air pressure in the second sub-cavity 103 is balanced, and at the same time, external dust and water vapor can be prevented from entering the second sub-cavity 103 through the first through hole 14, so as to avoid affecting the operation of the internal components of the first earphone body 100.

[0245] In some embodiments, the number of the pressure relief holes 24 is two, and the number of the second waterproof breathable membranes 94 is also two. The two pressure relief holes 24 and the two second waterproof breathable membranes 94 are arranged in a 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 there are multiple pressure relief holes 24, 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 1 mm 2 Up to 3mm 2 For example, the area of ​​the pressure relief hole 24 can be 1 mm 2 , 2mm 2 or 3mm 2 .

[0248] Fig. 27 yes Fig.24 FIG. 1 is a partial cross-sectional view of an embodiment of the first earphone body 100 at the section line II shown in FIG.

[0249] like Fig. 27 As shown, the feedback microphone 40 can be arranged near the sound-generating position of the speaker 30. For example, the feedback microphone 40 can be arranged in the first sub-cavity 102. The feedback microphone 40 can be arranged 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, near the ear canal. The sound near the ear canal of the user 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 arranging the feedback microphone 40 near the speaker 30, the feedback microphone 40 can be used to pick up the noise entering the vicinity of the ear canal of the user, and the sound on the speaker 30 side is fed back to the chip to output an anti-phase sound wave to offset the noise in the ear, and the user experience is better.

[0250] In some embodiments, the first earphone body 100 may further include a first magnet 95. Exemplarily, the first magnet 95 may be located in the first subcavity 102 and fixedly connected to the inner wall surface of the first housing 10. When the earphone 1000 is stored in an earphone box, the first magnet 95 may be used to cooperate with the magnet in the earphone box to generate suction and fix the position of the first earphone body 100 in the earphone box.

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

[0252] Fig.28 yes Fig.25 A schematic structural diagram of an embodiment of a wiring harness bracket 80 is shown in FIG. Fig.29 yes Fig.28 FIG. 8 is a schematic structural diagram of the wiring harness bracket 80 at another angle.

[0253] like Fig.28 and Fig.29 As shown, the 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 harness bracket 80 is provided with a threading channel 83, a first air vent 84 and a second air vent 85. The threading channel 83, the first air vent 84 and the second air vent 85 are arranged at intervals and are not connected to each other. Among them, the threading channel 83 connects the top surface 811 and the bottom surface 812. The first air vent 84 connects the bottom surface 812 and the peripheral side surface 813. The second air vent 85 connects 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 harness bracket 80. The peripheral side surface 813 of the bracket body 81 is the peripheral side surface of the 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 threading channel 83 and are arranged at intervals from each other. It is understandable 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 may 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 with the threading channel 83, the first air permeable pipe 84, and the second air permeable pipe 85.

[0256] Fig.30 yes Fig.24 FIG. 1 is a partial cross-sectional view of an embodiment of the first earphone body 100 at the section line HH shown in FIG.

[0257] like Fig.30As shown, the wiring harness bracket 80 is fixedly connected to the inner surface 22 of the second shell 20. Exemplarily, the peripheral side surface 813 of the wiring harness bracket 80 is connected to the inner surface 22 of the second shell 20. It is understandable that the peripheral side surface 813 of the wiring harness bracket 80 can be designed according to the shape of the inner surface 22 of the second shell 20, so that the shape of the peripheral side surface 813 roughly matches the shape of the inner surface 22 of the second shell 20. For example, the wiring harness bracket 80 can be roughly truncated cone-shaped. In this way, the connection area between the wiring harness bracket 80 and the second shell 20 can be increased and the connection strength can be strengthened. In some embodiments, the wiring harness bracket 80 can be fixedly connected to the second shell 20 by gluing.

[0258] The bottom surface 812 of the bracket body 81 faces the speaker 30. The first air permeable duct 84 and the second air permeable duct 85 can be respectively arranged opposite to and communicated with the two pressure relief holes 24. In this way, the second sub-cavity 103 can be connected to the outside through the first air permeable duct 84, the second air permeable duct 85 and the two pressure relief holes 24, so that the air pressure in the second sub-cavity 103 is balanced.

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

[0260] Fig.31 yes Fig.25 FIG. 1 is a schematic diagram of assembling a bone sensor 50 and a wiring harness support 80 according to an embodiment of the present invention. Fig.32 yes Fig.24 FIG. 1 is a partial cross-sectional view of an embodiment of the first earphone body 100 at the section line II shown in FIG.

[0261] like Fig.31 and Fig.32 As shown, the bone sensor 50 can be fixedly connected to the receiving groove 86 of the harness bracket 80. Exemplarily, the receiving groove 86 can form an opening on the bottom surface 812 and the peripheral side surface 813 of the bracket body 81. The bone sensor 50 can be fixedly connected to the receiving groove 86 of the harness bracket 80 and the space enclosed by the second housing 20.

[0262] The second earphone body 200 may further include a buffer 99. The buffer 99 may fill the gap between the second housing 20, the bone sensor 50 and the harness bracket 80. In this way, the buffer 99 may help fix the position of the bone sensor 50 and play a buffering role when it is impacted by external force. Exemplarily, the buffer 99 may be glue. In this way, while playing a buffering role, the buffer 99 may also strengthen the connection between the second housing 20 and the harness bracket 80 to improve reliability.

[0263] The first capacitive sensor 60 is disposed in 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 the first capacitive sensor 60 can also be called a proximity sensor in some embodiments, and can be used to detect whether the user is wearing the headset 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] Fig.33 yes Fig.25 A structural schematic diagram of an implementation manner of a first circuit board 70 is shown in FIG.

[0265] like Fig.33 As shown, the first circuit board 70 may 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. 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 part 71, the second part 72, the third part 73, the fourth part 74, the fifth part 75 and the sixth part 76 can be an integral structural member. For example, the first circuit board 70 can be a flexible circuit board. In this way, the first circuit board 70 can be cut into any shape according to the device and position to be connected, and then the corresponding part and the corresponding device can be connected and bent into a preset shape. Compared with the solution of achieving electrical connection through structures such as cables, the flexible circuit board is less difficult to assemble and the reliability of the electrical connection is better. In other embodiments, the first part 71, the second part 72, the third part 73, the fourth part 74, the fifth part 75 and the sixth part 76 can also be connected by wires.

[0267] Fig.34 yes Fig.24 A partial structural schematic diagram of an implementation manner of the first earphone body 100 is shown in FIG. Fig.35 yes Fig.34 A schematic diagram of the structure shown in FIG. 1 at another angle.

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

[0269] The fourth portion 74 can be used to connect a signal line to transmit signals from the speaker 30 , the harness bracket 80 , the bone sensor 50 , the first capacitive sensor 60 , and the feedback microphone 40 to the second earphone body 200 .

[0270] Fig.36 yes Fig. 27 An enlarged schematic diagram of an embodiment of the structure shown in FIG.

[0271] like Fig.36 As 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 a side surface of the first portion 71 away from the first housing 10. Along the X-axis direction, the first portion 71 can be arranged opposite to the first through hole 14. Exemplarily, the first portion 71 can be provided with a through hole 711. Along the X-axis direction, the through hole 711 can be arranged opposite to and communicate with the first through hole 14.

[0272] In some embodiments, the first housing 10 may be provided with a positioning pile 19. The positioning pile 19 may be disposed in the first sub-cavity 102. The positioning pile 19 may be used to assist in quickly positioning the first portion 71 during the process of installing the first portion 71 to the first housing 10. The first portion 71 may be provided with a positioning hole 712, and the positioning pile 19 is at least partially located in the positioning hole 712. The positioning hole 712 and the through hole 711 may be connected or may be arranged at intervals.

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

[0274] Fig.37 yes Figure 1 FIG. 1 is a cross-sectional view of an embodiment of the earphone 1000 at the 0-0 plane.

[0275] like Fig.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 ( Fig.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 headset 1000 is provided with a first capacitance sensor 60 on the first headset body 100 and a second capacitance sensor 290 on the second headset 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 headset 1000 according to the first capacitance value and the second capacitance value, that is, the wearing detection of the headset 1000. 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 Fig.37As shown, along the length direction of the connecting arm 300, the connecting arm 300 has a first end and a second end spaced apart, the first end connected to the first earphone body 100, and the second end connected to the second earphone body 200. In some embodiments, the central axis direction of the first end and the central axis direction of the second end are set at an angle, and the range of the angle is in 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 solution in which the central axis direction of the first end of the connecting arm 300 and the central axis direction of the second end of the connecting arm 300 are set in parallel, the first end and the second end of the connecting arm 300 are set at a certain angle. When the user wears the earphone 1000, the relative position of the first earphone body 100 and the second earphone body 200 can better fit the ear inclination and contour curve of the user, effectively reducing the pressure of the first earphone body 100 and the second earphone body 200 of the earphone 1000 on the earphone 1000, and the user's use experience is better.

[0287] Several implementations of the connecting arm 300 will be described in detail below with reference to the accompanying drawings. Fig.38 yes Figure 1 FIG. 4 is a cross-sectional view of one embodiment of a connecting arm 300 at section line KK. Fig.39 yes Fig.38 FIG. 4 is a cross-sectional view of one embodiment of the connecting arm 300 at the section line LL. Fig.40 yes Fig.38 FIG. 4 is a cross-sectional view of an embodiment of the connecting arm 300 shown in FIG. 3 at the section line MM.

[0288] like Fig.38 , Fig.39 and Fig.40 As shown, the connecting arm 300 may include a first connecting member 310, a second connecting member 320, a supporting member 330, a wiring harness 340, and a tube 350. The tube 350 is sleeved on the supporting member 330 and the wiring harness 340 to protect the supporting member 330 and the wiring harness 340, and can also be used for insulation of the wiring harness 340. The supporting member 330 is used to make the connecting arm 300 present a preset shape. The wiring 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. The first channel 351 and the second channel 352 are both arranged along the length direction of the tube body 350. The tube body 350 has a first end and a second end which are arranged opposite to each other. The first connector 310 is connected to the first end, and the second connector 320 is connected to the second end. The end face of the first end of the tube body 350 is a first end face 353. The end face of the second end of the tube body 350 is a second end face 354.

[0290] In some embodiments, the tube body 350 may be made of insulating material, such as thermoplastic polyurethane (TPU).

[0291] like Fig.39 As shown, the wiring harness 340 may be centrally located in the first channel 351, and the two ends may be exposed at the first end surface 353 and the second end surface 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 be exposed through the first through hole 314, and the other end may be exposed through the second through hole 321.

[0292] like Fig.40 As shown, the first connecting member 310 may be provided with a first cavity 315. The first cavity 315 and the first through hole 314 may be arranged at intervals. The second connecting member 320 may be provided with a second cavity 322. The second cavity 322 and the second through hole 321 may be arranged at intervals. The support member 330 may be centrally located in 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 a metal or other material with elasticity. Exemplarily, the support member 330 may be a metal wire made of a memory alloy. It is understandable that, compared with the solution of using ordinary metal materials to prepare the support member 330, using a 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, thereby preventing the support member 330 from losing its initial shape after being stretched multiple times.

[0294] In some embodiments, the central axis direction of the first connecting member 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 connecting member 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 connecting member 310 and the central axis direction of the second connecting member 320 may also be arranged at an angle. The angle ranges from 11.4° to 26°, for example, the angle may be 11.4°, 15°, 20° or 26°.

[0295] It is understandable that the central axis direction of the first connecting member 310 and the central axis direction of the second connecting member 320 can be realized by the shape of the support member 330 made of memory alloy. First, the support member 330 made of memory alloy is set to a preset shape, and then the support member 330 passes through the first channel 351 of the tube body 350, and one end of the support member 330 is fixedly connected to the first connecting member 310, and the other end is fixedly connected to the second connecting member 320. Then, under certain conditions, the support member 330 is restored to the preset shape. 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 central axis direction of the first connecting member 310 and the central axis direction of the second connecting member 320 can be set at a preset angle.

[0296] In some embodiments, 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 may also be arranged at an angle.

[0297] like Fig.38 As 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 deformation degree of the wire harness 340 can be smaller than the deformation degree of the tube body 350. In other words, when the connecting arm 300 is bent, the stretching amount of the wire harness 340 is smaller than the stretching amount of the tube body 350. In this way, the wire harness 340 is not easily broken and has a longer service life.

[0298] It can be understood that the connecting arm 300 can be used to connect the first earphone body 100 and the second earphone body 200, and realize signal transmission between the first earphone body 100 and the second earphone body 200. The following will specifically introduce an implementation method of the connecting arm 300 connecting the first earphone body 100 and the second earphone body 200 through the accompanying drawings, as well as a specific implementation method of the connecting arm 300 for realizing signal transmission between the first earphone body 100 and the second earphone body 200.

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

[0300] Fig.41 yes Fig.37 An enlarged view of an embodiment of the structure shown in FIG.

[0301] like Fig.37 and Fig.41 As shown, the first connecting member 310 may include a body portion 311, a first protrusion 312 and a second protrusion 313 ( Fig.41The main body 311, the first protrusion 312 and the second protrusion 313 are schematically distinguished by dotted lines. The first protrusion 312 and the second protrusion 313 are fixedly connected to the side surface 3111 of the main body 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 tube body 350, and the other end is connected to the first earphone body 100.

[0302] Exemplarily, the wall surface 3511 of the first channel 351 may be recessed to form a first groove 355. The first groove 355 and the first end surface 353 are spaced apart. The first protrusion 312 and part of the body 311 of the first connector 310 may be located in the first groove 355. Meanwhile, along the length direction of the first connector 310, part of the first end surface 353 is located between the first protrusion 312 and the second protrusion 313. It is understood that the first protrusion 312 may serve as a limiting structure to prevent the tube body 350 from falling off from the first connector 310.

[0303] The first groove 355 can be connected to the first channel 351. When the first connector 310 is fixedly connected to the tube body 350, the first through hole 314 is connected to the first channel 351. In this way, one end of the wire harness 340 can pass through the first through hole 314 and enter the second sub-cavity 103 of the first earphone body 100.

[0304] In some embodiments, the first protrusion 312 may be annular and sleeved to connect the side surface 3111 of the main body 311. In other embodiments, the first protrusion 312 may also include a plurality of sub-protrusions, which are spaced and connected to the side surface 3111 of the main body 311.

[0305] In some embodiments, when the tube body 350 is made of TPU, the TPU material is elastic, 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, so that the wall surface of the first groove 355 can support the first protrusion 312 and the main body 311, and the connection strength between the tube body 350 and the first connecting member 310 is better.

[0306] In some embodiments, when the first connector 310 is connected to the first earphone body 100, the first connector 310 is connected to the second housing 20. Exemplarily, the first connector 310 is partially located in the threading channel 83 of the harness bracket 80 and the second connecting hole 26 of the second housing 20. The inner wall surface of the threading channel 83 of the harness bracket 80 can be raised to form a protrusion 831. Along the length direction of the first connector 310. The protrusion 831 is located between the first protrusion 312 and the second protrusion 313 of the first connector 310, and is adjacent to the first end surface 353 of the tube body 350. It can be understood that the protrusion 831 of the harness bracket 80 can be used as a limiting structure to prevent the first connector 310 from falling off from the first earphone body 100 along the X-axis direction.

[0307] It is understandable that the way the second connector 320 connects the tube body 350 and the second earphone body 200 can refer to the way the first connector 310 connects the tube body 350 and the first earphone body 100, which will not be described in detail here. When the second connector 320 is connected to the second earphone body 200, the second connector 320 can be fixedly connected to the third housing 210 of the second earphone body 200.

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

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

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

[0313] As Fig.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 nine signal lines 341 into a whole, facilitating installation.

[0314] In some embodiments, the wire harness 340 may include nine signal lines. The nine signal lines 341 are respectively one signal line 341 for transmitting power, one signal line 341 for grounding, two signal lines 341 for connecting a capacitance sensor, two signal lines 341 for connecting a feedback microphone, two signal lines 341 for connecting a bone sensor, and two 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 restrictions.

[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 form 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 relatively low crosstalk requirements in the signal lines 341 can be in the form of twisted pairs. For example, the two signal lines 341 for connecting the capacitive sensor are in 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 in 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. Furthermore, 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 be in the form of twisted pairs.

[0319] Fig.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 Fig.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 Fig.13 and Fig.14 It can be seen that the feedback microphone 40, the speaker 30, the first capacitive sensor 60 and the bone sensor 50 in the first earphone body 100 are all electrically connected to the first circuit board 70. Fig.30 and Fig.31 It can be seen 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 capacitive sensor 60 and the bone sensor 50 in the first earphone body 100 can be transmitted to the main board 260 of the second earphone body 200 through the wire harness 340. The wire harness 340 can be used to transmit electrical signals between the first earphone body 100 and the second earphone body 200.

[0321] Fig.44 It is a schematic diagram of assembly of a wiring harness 340 , a first circuit board 70 , and a wiring harness bracket 80 in one embodiment.

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

[0323] Fig.45 It is a structural diagram of an implementation of the audio device 3000 provided in this application.

[0324] like Fig.45 As shown, the present application also provides an audio device 3000, which includes an earphone 1000 and an earphone box 2000. The earphone is arranged in the earphone box 2000. The earphone box 2000 can be used to store the earphone 1000. In some embodiments, the earphone box 2000 can also be used to charge the earphone 1000.

[0325] In some implementations, the audio device 3000 may include two headphones 1000 .

[0326] It should be noted that, in the absence of 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. In other words, the multiple embodiments described above can also be arbitrarily combined according to actual needs.

[0327] It should be noted that all the above drawings are illustrative illustrations of the present application and do not represent the actual size of the product. Moreover, the size ratio relationship between the components in the drawings is not intended to limit the actual product of the present application.

[0328] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
