[0032] The present invention is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0033] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0034] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0035] like Figure 1 As shown, the user's ear EAR may include the external auditory canal E11, the cavum concha E12, the cymba concha E13, the triangular fossa E14, the antihelix E15, the scaphoid E16, the helix E17, and the antitragus E18. Among them, although the external auditory canal E11 has a certain depth and extends to the eardrum of the ear EAR, for the convenience of description, and in combination with Figure 1 As shown, in the present application, unless otherwise specified, the external auditory canal E11 specifically refers to its entrance away from the tympanic membrane (i.e., the ear hole). Furthermore, the concha cavity E12, the hymena concha E13, the triangular fossa E14 and other physiological parts have a certain volume and depth; and the concha cavity E12 is directly connected to the external auditory canal E11, that is, the ear hole can be simply regarded as being located at the bottom of the concha cavity E12.

[0036] Furthermore, there is a tragus E19 outside the external auditory canal of the ear EAR, which has a certain depth and volume in three-dimensional space compared to the cavum concha E12, the cymba concha E13 and the triangular fossa E14, that is, these parts are respectively concave toward the back side of the ear EAR in the direction close to the user's head, and the tragus E19 is convex toward the front side of the ear EAR in the direction away from the user's head. Among them, "the front side of the ear EAR" is a concept relative to the "back side of the ear EAR", the former refers to the side of the ear EAR away from the head, for example Figure 1 , the latter refers to the side of the ear EAR facing the head, and they are all aimed at the user's ear EAR.

[0037] Furthermore, different users may have individual differences, resulting in different shapes, sizes and other dimensional differences in the ear EAR. In order to facilitate description and reduce (or even eliminate) individual differences between different users, a simulator containing a head and its (left and right) ear EARs can be made based on ANSI: S3.36, S3.25 and IEC: 603187 standards, such as GRAS45BCKEMAR. Therefore, descriptions such as "the user wears the earphones", "the earphones are in a wearing state" and "in a wearing state" may refer to the ear EAR of the earphones described in this application worn on the aforementioned simulator. Of course, precisely because different users have individual differences, the earphones may be worn by different users and there may be certain differences in the ear EAR of the earphones worn on the aforementioned simulator, but such differences should be tolerated.

[0038] It should be noted that in the fields of medicine and anatomy, three basic planes of the human body can be defined: the sagittal plane, the coronal plane, and the horizontal plane, as well as three basic axes: the sagittal axis, the coronal axis, and the vertical axis. Among them, the sagittal plane refers to a plane perpendicular to the ground along the front-back direction of the body, which divides the human body into left and right parts; the coronal plane refers to a plane perpendicular to the ground along the left-right direction of the body, which divides the human body into front and back parts; the horizontal plane refers to a plane parallel to the ground along the up-down direction of the body, which divides the human body into upper and lower parts. Correspondingly, the sagittal axis refers to an axis along the front-back direction of the body and perpendicular to the coronal plane, the coronal axis refers to an axis along the left-right direction of the body and perpendicular to the sagittal plane, and the vertical axis refers to an axis along the up-down direction of the body and perpendicular to the horizontal plane. Furthermore, the "front side of the ear EAR" described in this application is a concept relative to the "back side of the ear EAR". The former refers to the side of the ear EAR away from the head, and the latter refers to the side of the ear EAR facing the head. They are both for the user's ear EAR. Among them, by observing the ear EAR of the above simulator along the direction of the human coronal axis, it can be obtained Figure 1 The front profile of the ear is shown in Figure 1. Figure 1 , the three directions of X, Y and Z can be simply regarded as the coronal axis, sagittal axis and vertical axis of the human body respectively; the three planes of XY, XZ and YZ can be simply regarded as the horizontal plane, coronal plane and sagittal plane of the human body respectively.

[0039] The present application embodiment describes at least one exemplary structure of the earphone 1. Figure 1 As shown, Figure 1 FIG. 1 shows a state where the earphone 1 is worn on the user's ear EAR. The earphone 1 may be an ear clip type earphone. Figures 1 to 3 As shown, the earphone 1 includes a sound-emitting portion 100 for inserting into the concha cavity E12 of the user (user), a contact portion 300 for contacting behind the user's ear, and an ear hook 200 connected to the sound-emitting portion 100 and the contact portion 300. In the wearing state, the ear hook 200 can bypass the user's helix E17, and the sound-emitting portion 100 and the contact portion 300 form a clamping state on both sides of the user's helix E17, and the sound-emitting portion 100 and the contact portion 300 form a clamping state, and the sound-emitting portion 100 is located in the concha cavity E12. The sound-emitting portion 100 is a sound playing device, which is used to convert an electrical signal into an acoustic signal and play it to the wearer. The contact portion 300 forms a clamping state with the sound-emitting portion 100 so that the entire earphone 1 is clamped and worn on the user's ear EAR. In some embodiments, the contact portion 300 may be provided with devices such as batteries and circuit boards. Of course, the contact portion 300 may also be used without a battery, and the battery may be installed in the sound-emitting portion 100.

[0040] In some embodiments, Figure 4 As shown, the ear hook 200 has a symmetry plane A1 arranged along the length direction F1 of the ear hook 200. Specifically, the symmetry plane A1 of the ear hook 200 refers to the part arranged along the length direction F1 of the ear hook 200, and the difference of the parts of the ear hook 200 on both sides of the symmetry plane A1 is minimal or consistent, that is, if the ear hook 200 is regularly symmetrical, then the parts of the ear hook 200 on both sides of the symmetry plane A1 are consistent, and if the ear hook 200 is not strictly symmetrical, then the difference of the ear hook 200 on both sides of the symmetry plane A1 should be the smallest among various division methods, for example, the size of the difference can be distinguished by observing the projection of the ear hook 200 on a plane perpendicular to the symmetry plane A1.

[0041] Alternatively, if Figure 4 , Figure 5 and Figure 6 As shown, the abutment portion 300 includes a first shell 31 and a first microphone 32 disposed in the first shell 31, and the first microphone 32 collects the first sound through the first sound inlet 3101 on the first shell 31. The sound-emitting portion 100 includes a second shell 11 and a second microphone 12 disposed in the second shell 11, and the second microphone 12 collects the second sound through the second sound inlet 1101 on the second shell 11. The earphone 1 also includes a processing circuit 400 for performing noise reduction processing based on the first sound and the second sound. Among them, the earphone 1 also has a first reference plane A2 located below the symmetry plane A1 and parallel to the symmetry plane A1 in the wearing state, and the distance from the first reference plane A2 to the symmetry plane A1 is less than or equal to 5mm, for example, it can be 1mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, etc., of course, it can also be other values. The first sound inlet 3101 has a sound inlet end 301 located on the outer wall surface of the first shell 31. External sound is introduced into the first sound inlet 3101 from the sound inlet end 301 and transmitted to the first microphone 32 via the first sound inlet 3101. The entirety of the sound inlet end 301 of the first sound inlet 3101 is located on the side of the first reference plane A2 facing the symmetry plane A1.

[0042] The processing circuit 400 can perform noise reduction processing based on the first sound and the second sound. For example, the first sound inlet 3101 and the second sound inlet 1101 can be set at different positions so that the sounds introduced by the two have a certain difference, thereby making the sounds collected by the first microphone 32 and the second microphone 12 have different signal amplitudes in the main audio receiving band. The main audio receiving band can be, for example, the human voice audio receiving band, so that the processing circuit 400 can use the first sound and the second sound to identify and eliminate noise.

[0043] By setting the entire sound input end 301 of the first sound input hole 3101 to be located on the side of the first reference plane A2 facing the symmetry plane A1, the position of the sound input end 301 of the first sound input hole 3101 is restricted. On the one hand, the sound input end 301 of the first sound input hole 3101 can be largely blocked by the user's auricle E17 when the earphone 1 is worn, while the second sound input hole 1101 arranged in the sound-emitting part 100 is closer to the user's mouth and is not blocked, thereby improving the difference between the sounds introduced by the first sound input hole 3101 and the second sound input hole 1101, that is, improving the difference between the first sound collected by the first microphone 32 and the second sound collected by the second microphone 12, which is beneficial to improving the noise reduction effect of the processing circuit 400 using the first sound and the second sound for noise reduction processing. On the other hand, it will also make the connection between the first sound input hole 3101 and the second sound input hole 1101 have better directionality to the mouth, which is beneficial to improving the sound reception effect of the earphone 1 and enhancing the user experience.

[0044] Alternatively, if Figure 4 As shown, the sound input end 301 of the first sound input hole 3101 is at least partially located on the side of the symmetry plane A1 facing the first reference plane A2, and the maximum straight-line distance L1 from the hole edge of the sound input end 301 of the first sound input hole 3101 located on the side of the symmetry plane A1 facing the first reference plane A2 to the symmetry plane A1 is less than or equal to 4 mm, for example, it can be 0.5 mm, 1 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, etc., and of course it can also be other values.

[0045] See also Figure 1 Since the user's auricle E17 is in an outward convex arc shape as a whole, and the upper part along the vertical axis of the human body is more convex than the lower part, therefore, in the wearing state, the higher the sound input end 301 of the first sound input hole 3101 is, the greater the degree of blocking of the first sound input hole 3101 by the user's convex auricle E17 is, the greater the difference between the first sound collected by the first microphone 32 and the second sound collected by the second microphone 12 is, and the more conducive to improving the noise reduction effect.

[0046] By setting the maximum straight-line distance L1 from the hole edge of the sound input end 301 of the first sound input hole 3101, which is located on the side of the symmetry plane A1 facing the first reference plane A2, to less than or equal to 4 mm, the user's protruding auricle E17 can better block the first sound input hole 3101 when worn, and the line connecting the first sound input hole 3101 and the second sound input hole 1101 has better directionality to the mouth, which is beneficial to improve the difference between the first sound collected by the first microphone 32 and the second sound collected by the second microphone 12.

[0047] Alternatively, if Figure 7As shown, the earphone 1 is configured to support a left-ear wearing state and a right-ear wearing state, that is, the earphone 1 can be worn on the user's left ear or on the user's right ear. There are two first reference planes A2, which are symmetrically arranged on both sides of the symmetry plane A1, one of which is located below the symmetry plane A1 when the earphone 1 is in the left-ear wearing state, and the other first reference plane A2 is located below the symmetry plane A1 when the earphone 1 is in the right-ear wearing state, and the sound inlet end 301 of the first sound inlet hole 3101 is located as a whole between the two first reference planes A2.

[0048] The earphone 1 is not limited to being worn only on the left ear or only on the right ear, but is configured to be worn on both the left ear and the right ear. That is, when the user switches the earphone 1 from being worn on the left ear to being worn on the right ear, or from being worn on the right ear to being worn on the left ear, the state of the earphone 1 relative to the ear EAR remains unchanged, that is, the orientation of the sound outlet 1102 and the pressure relief hole 1103 on the earphone 1 relative to the external auditory canal E11 remains unchanged, and there is no difference in the look and feel when worn on the left or right ear. Furthermore, the earphone 1 will automatically identify the ear EAR being worn, and use control logic that matches it to change the function of the earphone 1 when worn on different ear EARs, such as the selection of left and right ear sound channels, or the switching of touch functions. By setting the sound input end 301 of the first sound input hole 3101 as a whole to be located between the two first reference planes A2, the sound input end 301 of the first sound input hole 3101 can be largely blocked by the user's auricle E17 regardless of whether the earphone 1 is worn on the left ear or the right ear, and ensuring that the line connecting the first sound input hole 3101 and the second sound input hole 1101 has good directionality to the mouth, so that the earphone 1 can achieve good noise reduction effect whether it is worn on the left ear or on the right ear, which is beneficial to improving the sound reception effect of the earphone 1, and is beneficial to improving the consistency of the earphone 1 when worn on the left ear and on the right ear, which is beneficial to improving the user experience.

[0049] Alternatively, if Figure 7 As shown, there are two first sound inlet holes 3101, and the sound inlet ends 301 of the two first sound inlet holes 3101 are arranged on both sides of the symmetry plane A1, and are all located as a whole between the two first reference planes A2. When the earphone 1 is worn on the left ear or the right ear, the relative positions of the first sound inlet hole 3101 and the ear EAR are close or even basically the same, so that when the earphone 1 is interchanged between the left and right ears, a relatively close noise reduction effect can be achieved, which is beneficial to improving the sound reception effect of the earphone 1 and enhancing the user experience.

[0050] Alternatively, if Figure 7As shown, the sound inlet ends 301 of the two first sound inlet holes 3101 are symmetrically arranged relative to the symmetry plane A1, so that the earphone 1 can achieve the same noise reduction effect when the left and right ears are interchanged. In addition, the symmetrical arrangement is also conducive to improving the aesthetic appearance.

[0051] Alternatively, if Figure 3 or Figure 4 As shown, the number of the first microphone 32 is one, and the first microphone 32 collects the first sound through two first sound inlet holes 3101. The sound inlet ends 301 of the two first sound inlet holes 3101 are spaced apart from each other, and the two first sound inlet holes 3101 are connected to each other. The two first sound inlet holes 3101 connected to each other are conducive to maintaining air pressure balance. Specifically, airflow can flow in from one of the first sound inlet holes 3101 and flow out through the other first sound inlet hole 3101, thereby helping to reduce wind noise in the first sound collected by the first microphone 32. The structure is simple and can save installation space.

[0052] In some embodiments, the number of the first sound inlet hole 3101 can also be one, and the symmetry plane A1 passes through the first sound inlet hole 3101, so that the earphone 1 can achieve the same noise reduction effect whether it is worn on the left ear or the right ear. In this case, whether it is worn on the left ear or the right ear, the sound input end 301 of the first sound inlet hole 3101 can be blocked by the user's auricle E17 to a large extent, and the line connecting the first sound inlet hole 3101 and the second sound inlet hole 1101 has good directivity to the mouth, which is conducive to improving the noise reduction effect, improving the sound reception effect of the earphone 1, and improving the user experience.

[0053] In addition, in some embodiments, the number of the first microphones 32 may be two, and each first microphone 32 corresponds to a first sound input hole 3101 . The present application does not impose any limitation on this, and those skilled in the art may make a selection according to actual needs.

[0054] Alternatively, if Figure 8 As shown, the earphone 1 can be configured to support only the left ear wearing state or only the right ear wearing state, and the sound input end 301 of the first sound input hole 3101 is located as a whole on the side of the symmetry plane A1 away from the first reference plane A2, so as to enhance the shielding effect of the user's auricle E17 on the sound input end 301 of the first sound input hole 3101 when the earphone 1 is worn, and make the line connecting the first sound input hole 3101 and the second sound input hole 1101 more pointed to the mouth, which is beneficial to increase the difference between the sounds introduced by the first sound input hole 3101 and the second sound input hole 1101, thereby enhancing the noise reduction processing effect of the earphone 1.

[0055] Alternatively, if Figure 8The minimum straight-line distance L2 from the hole edge of the sound inlet end 301 of the first sound inlet hole 3101 to the symmetry plane A1 is greater than or equal to 5 mm, for example, it can be 5.5 mm, 6 mm, 6.5 mm, 7 mm, etc., and of course it can also be other values. Wherein, when there are two first sound inlet holes 3101 connected to each other, the minimum straight-line distance L2 refers to the minimum straight-line distance from the hole edge of the first sound inlet hole 3101 closer to the symmetry plane A1 to the symmetry plane A1, or the smaller of the minimum straight-line distances from the hole edges of the two first sound inlet holes 3101 to the symmetry plane A1.

[0056] By setting the minimum straight-line distance L2 from the sound input end 301 of the first sound input hole 3101 to the symmetry plane A1 to be greater than or equal to 5 mm, the sound input end 301 of the first sound input hole 3101 is far away from the symmetry plane A1 to a greater extent, which is beneficial to improving the shielding effect of the sound input end 301 of the first sound input hole 3101 by the user's auricle E17 when the earphone 1 is worn, and makes the line connecting the first sound input hole 3101 and the second sound input hole 1101 point more toward the mouth, which is beneficial to improving the noise reduction processing effect of the earphone 1.

[0057] Alternatively, if Figure 8 As shown, the first shell 31 includes a main body 311, and the main body 311 includes a peripheral side wall 3111 and two oppositely arranged end walls 3112. The peripheral side wall 3111 is used to contact the back side of the helix E17. The first sound inlet 3101 can also be set on the peripheral side wall 3111 and is located on the side of the peripheral side wall 3111 away from the sound-emitting part 100. In some embodiments, the first sound inlet 3101 can be set on the end wall 3112, and the present application does not limit this. Those skilled in the art can make a choice according to actual needs. Optionally, as Figure 6 As shown, the second sound inlet 1101 has a sound inlet end 101 located on the outer wall surface of the second shell 11, and the minimum straight-line distance L3 between the hole edge of the sound inlet end 101 of the second sound inlet 1101 and the hole edge of the sound inlet end 301 of the first sound inlet 3101 is greater than or equal to 15 mm, for example, it can be 15 mm, 18 mm, 20 mm, 30 mm, etc., and of course it can also be other values.

[0058] By setting the minimum straight-line distance L3 between the hole edge of the sound input end 101 of the second sound input hole 1101 and the hole edge of the sound input end 301 of the first sound input hole 3101 to be greater than or equal to 15 mm, the difference between the first sound collected by the first microphone 32 and the second sound collected by the second microphone 12 can be improved, which is beneficial to improving the noise reduction effect of the processing circuit 400 using the first sound and the second sound for noise reduction processing, which is beneficial to improving the sound reception effect of the earphone 1 and enhancing the user experience.

[0059] Alternatively, if Figure 4 and Figure 5 As shown, along the width direction F2 of the ear hook 200 , the sound input end 301 of the first sound input hole 3101 and the sound input end 101 of the second sound input hole 1101 are respectively arranged to at least partially overlap with the ear hook 200 .

[0060] Specifically, the symmetry plane A1 is perpendicular to the width direction F2 of the ear hook 200, and a straight line perpendicular to the symmetry plane A1 and parallel to the width direction F2 of the ear hook 200 is used as a reference line A3. When the ear hook 200 is projected along the symmetry plane A1 to the reference line A3, it has a first projection width S1. When the sound input end 301 of the first sound input hole 3101 is projected along the symmetry plane A1 to the reference line A3, it has a second projection width S2. When the sound input end 101 of the second sound input hole 1101 is projected along the symmetry plane A1 to the reference line A3, it has a third projection width S3. The second projection width S2 and the third projection width S3 respectively overlap with the first projection width S1 at least partially, so that the ear hook 200 can form a barrier between the sound input end 301 of the first sound input hole 3101 and the sound input end 101 of the second sound input hole 1101, thereby improving the difference between the first sound collected by the first microphone 32 and the second sound collected by the second microphone 12, which is beneficial to improving the noise reduction processing effect of the earphone 1.

[0061] Alternatively, if Fig. 9 As shown, the first sound inlet 3101 has a first axial direction F3 pointing to the outside of the first shell 31, and the second sound inlet 1101 has a second axial direction F4 pointing to the outside of the second shell 11, and the angle J1 between the orthographic projection of the first axial direction F3 on the symmetry plane A1 and the orthographic projection of the second axial direction F4 on the symmetry plane A1 is greater than or equal to 115 degrees, for example, it can be 115 degrees, 120 degrees, 125 degrees, 130 degrees, etc., and of course it can also be other values.

[0062] The first axial direction F3 of the first sound inlet 3101 can be specifically determined by the following method: when a reference cylinder matching the size of the first sound inlet 3101 is passed through the first sound inlet 3101, the axial direction of the reference cylinder is the first axial direction F3 of the first sound inlet 3101. It should be noted that the "matching in size" described here means that the reference cylinder can just pass through the first sound inlet 3101 and is not easy to fall out of it.

[0063] The method for determining the second axial direction F4 of the second sound inlet hole 1101 may refer to the method for determining the first axial direction F3 of the first sound inlet hole 3101 , and will not be described in detail here.

[0064] By setting the angle J1 between the orthographic projection of the first axial direction F3 on the symmetry plane A1 and the orthographic projection of the second axial direction F4 on the symmetry plane A1 to be greater than or equal to 115 degrees, the orientations of the first sound inlet 3101 and the second sound inlet 1101 are different to a certain extent, so that the sounds introduced by the two also have a certain difference, which further improves the difference between the first sound collected by the first microphone 32 and the second sound collected by the second microphone 12, which is beneficial to improving the noise reduction processing effect of the earphone 1.

[0065] Alternatively, if Figure 4 and Figure 8 As shown, the first shell 31 includes a main body 311 and a transition part 312. The transition part 312 is arranged on the outer circumference of the main body 311 and connected to the ear hook 200. The transition part 312 is arranged in a tapered shape in the direction away from the main body 311, so that the ear hook 200 is smoothly connected to the outer surface of the main body 311. Among them, the first microphone 32 is arranged in the transition part 312, and the first sound inlet 3101 is arranged on the transition part 312 to make full use of the space of the transition part 312, which is conducive to improving the space utilization rate of the earphone 1 and making the structure of the earphone 1 more compact.

[0066] Optionally, the processing circuit 400 is further configured to perform wind noise detection based on the first sound and / or the second sound, and when the wind noise is detected to be greater than or equal to a preset threshold, control the first microphone 32 to be in a working state, and control the second microphone 12 to be in a non-working state. The working state means that the microphone is turned on, and the sound collected by it can be used by the processing circuit 400, and the non-working state means that the microphone is turned off, or the microphone is turned on, but the sound collected by it is not used by the processing circuit 400.

[0067] Among them, the processing circuit 400 performs wind noise detection based on the first sound and / or the second sound, which means that the processing circuit 400 identifies the sound signal characteristics in the first sound and / or the second sound to determine whether there are characteristics of the wind noise signal therein, so as to detect whether there is wind noise therein and how strong the wind noise is.

[0068] Since the sound input end 301 of the first sound input hole 3101 is largely blocked by the user's auricle E17 when worn, and the sound input end 101 of the second sound input hole 1101 is not blocked, the wind noise introduced by the second sound input hole 1101 will be greater than the sound introduced by the first sound input hole 3101. Therefore, when the processing circuit 400 detects that the wind noise is greater than or equal to the preset threshold, the first microphone 32 is controlled to be in a working state, and the second microphone 12 is controlled to be in a non-working state, thereby avoiding the second microphone 12 from collecting sound with excessive wind noise to affect the sound reception effect of the headset 1, which is beneficial to improving the user experience.

[0069] In some implementations, such as Figure 5 As shown, the abutting portion 300 includes two first microphones 32, and the two first microphones 32 are used to collect first sounds respectively. The sound-emitting portion 100 includes a second microphone 12, and the second microphone 12 is used to collect second sounds. The earphone 1 also includes a detection element 500 and a processing circuit 400. The detection element 500 is used to detect the relative position relationship of the two first microphones 32 in the wearing state, and the relative position relationship may refer to the relative upper and lower relationship between the two first microphones 32 in the gravity direction F5 in the wearing state. The processing circuit 400 controls one of the two first microphones 32 that is relatively upper along the gravity direction F5 to be in a working state according to the detection result of the detection element 500, and controls the other one that is relatively lower along the gravity direction F5 to be in a non-working state, and further performs noise reduction processing based on the first sound collected by the first microphone 32 in the working state and the second sound collected by the second microphone 12.

[0070] The working state means that the microphone is turned on and the sound collected by it can be used by the processing circuit 400, while the non-working state means that the microphone is turned off, or the microphone is turned on but the sound collected by it is not used by the processing circuit 400.

[0071] On the one hand, when the earphone 1 is in the worn state, the higher the position of the first microphone 32 is, the easier it is to be blocked by the ear helix E17, so that the difference in sound reception between the first microphone 32 and the second microphone 12 is greater; on the other hand, when the earphone 1 is in the worn state, the higher the position of the first microphone 32 is, the better the connection line between the first microphone 32 and the second microphone 12 can point to the mouth, which will also make the difference in sound reception between the first microphone 32 and the second microphone 12 greater. Therefore, by setting two first microphones 32, when the earphone 1 is in the worn state, no matter whether the earphone 1 is worn on the left ear or the right ear, the one of the two first microphones 32 that is relatively higher along the gravity direction F5 is in a working state, which is beneficial to improve the difference between the first sound collected by the first microphone 32 and the second sound collected by the second microphone 12, and is beneficial to improving the noise reduction processing effect of the earphone 1, while realizing the left and right ear interchangeability function of the earphone 1, ensuring the sound reception effect of the earphone 1, and improving the user experience.

[0072] Alternatively, if Fig.10 As shown, the ear hook 200 has a symmetry plane A1 set along the length direction F1 of the ear hook 200, and the abutting portion 300 also includes a first shell 31, and two first sound inlet holes 3101 are set on the first shell 31. Each first microphone 32 collects the first sound through a corresponding first sound inlet hole 3101, and the two first sound inlet holes 3101 respectively have sound inlet ends 301 located on the outer wall surface of the first shell 31, and the sound inlet ends 301 of the two first sound inlet holes 3101 are set on both sides of the symmetry plane A1.

[0073] By setting a corresponding first sound input hole 3101 for each of the two first microphones 32, and setting the sound input ends 301 of the two first sound input holes 3101 on both sides of the symmetry plane A1, when the first microphone 32 relatively upper along the gravity direction F5, that is, the first microphone 32 located above the symmetry plane A1, is in a working state, the sound input end 301 of its corresponding first sound input hole 3101 is also located above the symmetry plane A1. In this way, no matter whether the earphone 1 is worn on the left ear or the right ear, the user's auricle E17 can block the first microphone 32 in the working state to a large extent, and make the connection line between the first microphone 32 in the working state and the second microphone 12 point more to the mouth, thereby improving the difference between the first sound collected by the first microphone 32 and the second sound collected by the second microphone 12, improving the noise reduction processing effect of the earphone 1, and ensuring the sound reception effect of the earphone 1 while realizing the left and right ear interchangeability function of the earphone 1, which is conducive to improving the user experience.

[0074] Alternatively, if Fig.10 As shown, the sound input ends 301 of the two first sound input holes 3101 are symmetrically arranged relative to the symmetry plane A1, so that when the earphone 1 is interchanged between the left and right ears, the two first sound input holes 3101 can achieve the same sound introduction effect, thereby making the earphone 1 able to achieve good noise reduction processing effect whether worn on the left ear or the right ear, and is conducive to improving the aesthetics of the earphone 1.

[0075] Alternatively, if Fig.10 As shown, the first shell 31 includes a main body 311, and the main body 311 includes a peripheral side wall 3111 and two oppositely arranged end walls 3112. The peripheral side wall 3111 is used to contact the back side of the helix E17, and the two first sound inlet holes 3101 are respectively arranged on the two end walls 3112 of the abutting portion 300, thereby further improving the shielding effect of the user's helix E17 on the first sound inlet hole 3101 corresponding to the first microphone 32 in a working state in the wearing state, so that the connection line between the first microphone 32 in a working state and the second microphone 12 can better point to the mouth, thereby effectively improving the difference between the first sound and the second sound, which is beneficial for the processing circuit 400 to achieve a good noise reduction processing effect.

[0076] Alternatively, if Fig.10 As shown, in the vertical direction F6 of the symmetry plane A1, the shortest straight-line distance L4 of the hole edges of the sound inlet ends 301 of the two first sound inlet holes 3101 is greater than or equal to 10 mm, for example, it can be 11 mm, 12 mm, 13 mm, 15 mm, 18 mm, 20 mm, etc., and of course it can also be other values.

[0077] By setting the shortest straight-line distance L4 of the hole edges of the sound input ends 301 of the two first sound input holes 3101 to be greater than or equal to 10 mm, so that there is a certain distance between the two first sound input holes 3101, when the earphone 1 is in the worn state, the first sound input hole 3101 corresponding to the first microphone 32 in the working state can be better blocked by the user's auricle E17, and the connection line between the first microphone 32 in the working state and the second microphone 12 can be better pointed to the mouth, which is beneficial to improve the difference between the sounds collected by the first microphone 32 and the second microphone 12, and improve the noise reduction processing effect of the earphone 1.

[0078] Alternatively, if Fig.10 As shown, the shortest straight-line distance L5 from the sound inlet ends 301 of the two first sound inlet holes 3101 to the symmetry plane A1 is greater than or equal to 5 mm, for example, it can be 5.5 mm, 6 mm, 8 mm, 10 mm, 15 mm, etc., and of course it can also be other values.

[0079] So that there is a certain distance between the sound input ends 301 of the two first sound input holes 3101 and the symmetry plane A1. In this way, when the earphone 1 is worn, the first sound input hole 3101 corresponding to the first microphone 32 in working state can be better blocked by the user's earlobe E17, which is beneficial to improve the difference between the sounds collected by the first microphone 32 and the second microphone 12, and the connection line between the first microphone 32 in working state and the second microphone 12 can better point to the mouth, thereby improving the noise reduction processing effect of the earphone 1.

[0080] Alternatively, if Fig.11 As shown, the two first sound inlet holes 3101 are both disposed on the peripheral side wall 3111 of the abutting portion 300 , and are located on a side of the peripheral side wall 3111 facing away from the sound emitting portion 100 .

[0081] Since at least one of the two end walls 3112 of the abutting portion 300 is provided with an antenna for the earphone 1 to perform wireless radio frequency connection and / or a touch area for the user to perform touch operations, if the first sound inlet hole 3101 is provided on the end wall 3112, it may cause interference between the antenna and / or the touch area and the first sound inlet hole. Therefore, by providing the first sound inlet hole 3101 on the peripheral side wall 3111, the possibility of interference between the first sound inlet hole 3101 and the antenna and / or the touch area can be effectively reduced, which is beneficial to improving the stability and reliability of the operation of the earphone 1.

[0082] Optionally, the processing circuit 400 is configured to perform wind noise detection based on the first sound and / or the second sound, and when it is detected that the wind noise is greater than or equal to a preset threshold, the processing circuit 400 also controls the one of the two first microphones 32 that collects the first sound with less wind noise to be in a working state, and controls the other of the two first microphones 32 to be in a non-working state, so that the earphone 1 can obtain the first sound with relatively less wind noise, which is beneficial to achieving a good sound reception effect of the earphone 1 and improving the user experience.

[0083] Optionally, the processing circuit 400 is also configured to perform wind noise detection based on the first sound and / or the second sound, and when the wind noise is detected to be greater than or equal to a preset threshold, the processing circuit 400 also controls the other of the two first microphones 32 that is relatively lower along the gravity direction F5 to be in a working state, and controls the second microphone 12 to be in a non-working state.

[0084] Since the sound input end 301 of the first sound input hole 3101 is largely blocked by the user's auricle E17 when worn, and the sound-generating part 100 is located in the concha cavity E12 and is not blocked, the wind noise of the sound collected by the second microphone 12 will be greater than the sound collected by the first microphone 32. When the wind noise is detected to be greater than or equal to the preset threshold, the processing circuit 400 can control the second microphone 12 to be in a non-working state and one of the two first microphones 32 to be in a working state. Since the sound input end 301 of the first sound input hole 3101 corresponding to the one of the two first microphones 32 that is relatively lower along the gravity direction F5 is closer to the user's mouth, in some embodiments, only the relatively lower first microphone 32 is in a working state, and the first sound collected by the first microphone 32 can collect the user's voice as clearly and completely as possible while taking into account the lower wind noise, thereby facilitating the realization of a good sound collection effect of the earphone 1 and improving the user's experience.

[0085] Alternatively, if Fig.12 As shown, the sound-emitting part 100 includes a second shell body 11, a second sound inlet hole 1101 is arranged on the second shell body 11, and the second microphone 12 collects the second sound via the second sound inlet hole 1101. The second sound inlet hole 1101 has a sound inlet end 101 located on the outer wall surface of the second shell body 11, and the minimum straight-line distance L3 between the hole edge of the sound inlet end 301 of the first sound inlet hole 3101 and the hole edge of the sound inlet end 101 of the second sound inlet hole 1101 is greater than or equal to 15 mm, for example, it can be 15 mm, 17 mm, 20 mm, 25 mm, etc., and of course it can also be other values.

[0086] By setting the minimum straight-line distance L3 between the edge of the sound input end 301 of the first sound input hole 3101 and the edge of the sound input end 101 of the second sound input hole 1101 to be greater than or equal to 15 mm, it is ensured that there is a certain difference between the sounds introduced by the first sound input hole 3101 and the second sound input hole 1101, which is conducive to the processing circuit 400 to perform good noise reduction processing and improve the noise reduction processing effect of the earphone 1.

[0087] Alternatively, if Fig.12 As shown, the first sound inlet 3101 has a first axial direction F3 pointing to the outside of the first shell 31, and the second sound inlet 1101 has a second axial direction F4 pointing to the outside of the second shell 11, and the angle between the orthographic projection of the first axial direction F3 on the symmetry plane A1 and the orthographic projection of the second axial direction F4 on the symmetry plane A1 is greater than or equal to 115 degrees, for example, it can be 115 degrees, 120 degrees, 125 degrees, 130 degrees, etc., and of course it can also be other values.

[0088] In this embodiment, the method for determining the first axial direction F3 of the first sound inlet hole 3101 and the method for determining the second axial direction F4 of the second sound inlet hole 1101 may be the same or similar to the above-mentioned embodiments and will not be described in detail here.

[0089] By setting the angle between the orthographic projection of the first axial direction F3 on the symmetry plane A1 and the orthographic projection of the second axial direction F4 on the symmetry plane A1 to be greater than or equal to 115 degrees, the first sound inlet 3101 and the second sound inlet 1101 are respectively oriented in different directions, thereby ensuring that there is a certain difference between the sounds introduced by the first sound inlet 3101 and the second sound inlet 1101, effectively improving the difference between the first sound and the second sound, which is beneficial to improving the noise reduction processing effect of the earphone 1.

[0090] Alternatively, if Figure 5 and Fig.13 As shown, the earphone 1 also includes a switching device 600, and the two first microphones 32 are connected to the same audio port of the processing circuit 400 via the switching device 600. The processing circuit 400 controls the one of the two first microphones 32 that is relatively upper along the gravity direction F5 to be connected to the processing circuit 400 according to the detection result of the detection element 500, so that it is in a working state, and disconnects the other one that is relatively lower along the gravity direction F5 from the processing circuit 400, so that it is in a non-working state.

[0091] By providing the switching device 600 , it is convenient for the processing circuit 400 to control the switching of the two first microphones 32 according to the detection result of the detection element 500 , which is beneficial to improving the switching efficiency and reliability of the earphone 1 .

[0092] In some embodiments, the switching of the two first microphones 32 may be realized only by software, which is within the scope of understanding of those skilled in the art and will not be described in detail here.

[0093] In some embodiments, Figure 6 and Fig. 9 As shown, the sound-emitting portion 100 includes a shell and a microphone and a sound-emitting component 13 arranged in the shell. The shell may be the aforementioned second shell 11, and the microphone may be the aforementioned second microphone 12. The second shell 11 is provided with a sound inlet and a sound outlet 1102. The sound inlet may be the aforementioned second sound inlet 1101. The second microphone 12 collects external sound via the second sound inlet 1101, and the sound emitted by the sound-emitting component 13 is transmitted outward via the sound outlet 1102. The second sound inlet 1101 can be used to introduce sound into the second microphone 12, and the second microphone 12 can be used to collect the introduced sound. The second sound inlet 1101 has a sound inlet end 101 located on the outer wall surface of the second shell 11, and the sound outlet 1102 has a first sound outlet end 102 located on the outer wall surface of the second shell 11, as shown in FIG. Fig. 9 As shown, there is a first shortest straight line segment L6 between the hole edge of the sound input end 101 of the second sound input hole 1101 and the hole edge of the first sound output end 102. The length of the first shortest straight line segment L6 is greater than or equal to 9 mm, for example, it can be 9 mm, 10 mm, 12 mm, 15 mm, etc., and of course it can also be other values.

[0094] Since the propagation of sound follows the inverse square law, that is, the intensity of sound is inversely proportional to the square of the distance from the sound source, the farther away from the sound source, the smaller the intensity of the sound. By setting the length of the first shortest straight line segment L6 to be greater than or equal to 9 mm, it is effectively prevented that the sound transmitted outward from the sound outlet 1102 is introduced into the second sound inlet 1101, thereby interfering with the sound collection of the second microphone 12, effectively reducing the possibility of echo when the user uses the headset 1 to make a call, which is beneficial to improving the user's calling experience.

[0095] Alternatively, if Fig. 9 As shown, along the outer wall of the second shell 11, there is a shortest wall line with a common endpoint with the first shortest straight line segment L6 between the hole edge of the sound input end 101 of the second sound input hole 1101 and the hole edge of the first sound output end 102, which is called the first shortest wall line L7. Among them, the first shortest wall line L7 is specifically the shortest arc segment formed by the contour line of the outer wall of the second shell 11 between the hole edge of the sound input end 101 of the second sound input hole 1101 and the hole edge of the first sound output end 102. The first shortest wall line L7 is configured to protrude toward the outside of the second shell 11, and the length of the first shortest wall line L7 is greater than or equal to 13mm, for example, it can be 13mm, 15mm, 18mm, 20mm, etc., and of course it can also be other values.

[0096] By setting the length of the first shortest wall line L7 to be greater than or equal to 13 mm, it is helpful to improve the sound isolation effect of the second shell 11 between the second sound inlet 1101 and the sound outlet 1102, and further reduce the possibility that the sound transmitted outward from the sound outlet 1102 will interfere with the sound collection of the second microphone 12.

[0097] Optionally, the ratio of the length of the first shortest straight line segment L6 to the length of the first shortest wall line L7 is between 0.5 and 0.75, for example, it may be 0.55, 0.65, 0.7, etc., and of course it may be other values.

[0098] By setting the ratio between the length of the first shortest straight line segment L6 and the length of the first shortest wall line L7 to be between 0.5 and 0.75, it is beneficial to further improve the sound isolation effect of the second shell 11 between the second sound inlet 1101 and the sound outlet 1102, which is beneficial to improving the sound reception effect of the earphone 1.

[0099] Alternatively, if Figure 5 and Figure 6 As shown, the ear hook 200 has a symmetry plane A1 arranged along the length direction F1 of the ear hook 200, and the symmetry plane A1 passes through the sound input end 101 and the first sound output end 102 of the second sound input hole 1101 respectively, and in the wearing state, the sound input end 101 of the second sound input hole 1101 is located on the side of the second shell 11 away from the helix E17, and is closer to the ear hook 200 than the first sound output end 102.

[0100] By arranging the sound input end 101 and the first sound output end 102 of the second sound input hole 1101 to intersect with the symmetry plane A1, on the one hand, the earphone 1 is more symmetrical in appearance, and on the other hand, the earphone 1 can be worn by both the left ear and the right ear, which is conducive to realizing the left-right ear interchangeability function and effectively improving the adaptability of the earphone 1.

[0101] In addition, the sound input end 101 of the second sound input hole 1101 is arranged to be located on the side of the second shell 11 away from the helix E17 in the wearing state, so that the second sound input hole 1101 can better import the voice emitted by the user's mouth, thereby effectively improving the applicability of the earphone 1. In the wearing state, the sound input end 101 of the second sound input hole 1101 is closer to the ear hook 200 than the first sound output end 102, avoiding the sound-emitting component 13, so that the sound-emitting component 13 can occupy a relatively large space, improving the space utilization rate in the second shell 11. In the wearing state, the first sound output end 102 of the sound output hole 1102 can be closer to the ear hole than the sound input end 101 of the second sound input hole 1101, so that the sound transmitted outward by the sound-emitting component 13 through the first sound output end 102 is more easily transmitted to the user's ear hole.

[0102] Alternatively, if Fig. 9 As shown, the second sound inlet 1101 has an axial direction pointing to the outside of the second shell 11, and the axial direction is called the second axial direction F4. The sound outlet 1102 has a second sound outlet end 103 located on the inner wall surface of the second shell 11, that is, the sound emitted by the sound-emitting component 13 is transmitted to the outside of the earphone 1 through the second sound outlet end 103 and the first sound outlet end 102 in sequence. There is a second shortest straight line segment L8 between the hole edge of the sound input end 101 of the second sound input hole 1101 and the hole edge of the second sound output end 103. The endpoint of the first shortest straight line segment L6 on the hole edge of the first sound output end 102 is used as the first reference point K1, and the endpoint of the second shortest straight line segment L8 on the hole edge of the second sound output end 103 is used as the second reference point K2. The sound output hole 1102 has a reference direction F7 pointing from the second reference point K2 to the first reference point K1, and the angle J2 between the orthographic projection of the second axis direction F4 on the symmetry plane A1 and the orthographic projection of the reference direction F7 on the symmetry plane A1 is greater than or equal to 70 degrees, for example, it can be 70 degrees, 75 degrees, 80 degrees, 90 degrees, etc., and of course it can also be other values.

[0103] By setting the angle J2 between the orthographic projection of the second axis direction F4 on the symmetry plane A1 and the orthographic projection of the reference direction F7 on the symmetry plane A1 to be greater than or equal to 70 degrees, the second sound inlet 1101 and the sound outlet 1102 have different orientations, thereby effectively reducing the possibility that the sound transmitted from the sound outlet 1102 will be introduced into the second sound inlet 1101, effectively reducing the possibility that the sound emitted by the sound-emitting component 13 will interfere with the sound collected by the second microphone 12, and effectively reducing the possibility of echo when the user uses the headset 1 to make a call, which is beneficial to improving the user's calling experience.

[0104] Alternatively, if Figure 3 As shown, the first sound outlet end 102 is arranged in a strip shape, and on the symmetry plane A1, the hole edge of the first sound outlet end 102 has a first endpoint K6 and a second endpoint K7 arranged at intervals along the length direction of the first sound outlet end 102, and the first endpoint K6 is closer to the sound input end 101 of the second sound input hole 1101 than the second endpoint K7.

[0105] By setting the first sound outlet end 102 into a strip shape, while ensuring the area of ​​the sound outlet 1102, when the earphone 1 is worn by the user, the second shell 11 and the concha cavity E12 of the user's ear EAR are not completely in contact, but there is a space that gradually increases from the contact area between the second shell 11 and the ear EAR to the ear canal opening, that is, a wedge-shaped space is formed, so that a horn structure is formed between the sound outlet 1102 and the concha cavity E12, and the concha cavity E12 is used as a reflective wall to form sound wave reflection enhancement. The sound output from the sound outlet 1102 will be reflected in the concha cavity E12 and enhanced, so as to utilize the reflection effect to increase the sound pressure at the ear canal opening, so that the user can hear a stronger sound, effectively improving the user experience.

[0106] Alternatively, if Figure 5 and Fig. 9 As shown, the first sound outlet end 102 and the sound input end 101 of the second sound input hole 1101 are symmetrically arranged relative to the symmetry plane A1, and the first shortest straight line segment L6 connects the first endpoint K6 and the position point of the hole edge of the sound input end 101 of the second sound input hole 1101 closest to the first endpoint K6. The earphone 1 also has a third shortest straight line segment L9 connecting the first endpoint K6 and the second endpoint K7. The angle J3 between the first shortest straight line segment L6 and the third shortest straight line segment L9 is less than or equal to 75 degrees, for example, it can be 60 degrees, 65 degrees, 70 degrees, 75 degrees, etc., and of course it can also be other values.

[0107] By setting the angle J3 between the first shortest straight line segment L6 and the third shortest straight line segment L9 to be less than or equal to 75 degrees, the direction of the sound outlet hole 1102 relative to the second sound inlet hole 1101 is further restricted, thereby effectively reducing the possibility that the sound transmitted from the sound outlet hole 1102 is introduced into the second sound inlet hole 1101, which is beneficial to improving the sound reception effect of the earphone 1.

[0108] Optionally, the length of the third shortest straight line segment L9 is greater than or equal to 7 mm, for example, it can be 7 mm, 10 mm, 13 mm, 15 mm, etc., and of course it can also be other values.

[0109] By setting the length of the third shortest straight line segment L9 to be greater than or equal to 7 mm, the size of the sound hole 1102 is more consistent with the size and shape of the concha cavity E12 and the ear hole, which is more convenient to form a horn structure for enhancing the sound, effectively improving the sound effect of the earphone 1, effectively increasing the sound pressure at the ear hole, and effectively increasing the listening volume.

[0110] Optional, such as Fig. 9As shown, the second sound inlet 1101 has an axial direction pointing to the outside of the second shell 11, and the axial direction is called the second axial direction F4. The angle J4 between the second axial direction F4 and the first shortest straight line segment L6 is greater than or equal to 40 degrees, for example, it can be 40 degrees, 45 degrees, 50 degrees, 55 degrees, etc., and of course it can also be other values.

[0111] By setting the angle J4 between the second axial direction F4 and the first shortest straight line segment L6 to be greater than or equal to 40 degrees, the direction of the second sound inlet 1101 relative to the sound outlet 1102 is further restricted, thereby effectively reducing the possibility of the sound transmitted from the sound outlet 1102 being introduced into the second sound inlet 1101, which is beneficial to improving the sound reception effect of the earphone 1.

[0112] Alternatively, if Fig. 9 As shown, on the symmetry plane A1, the outer wall surface of the second shell 11 has a third reference point K3 closest to the abutting portion 300, the inner contour of the ear hook 200 in the wearing state has a fourth reference point K4 farthest from the third reference point K3 in the area close to the edge of the helix, and the outer wall surface of the second shell 11 further has a fifth reference point K5 farthest from the fourth reference point K4, and the first sound outlet end 102 and the sound input end 101 of the second sound input hole 1101 are located on both sides of the fifth reference point K5.

[0113] In the natural state, the outer wall surface of the sound-emitting part 100 and the outer wall surface of the abutting part 300 do not abut each other, and there is a position where the distance between the outer wall surface of the sound-emitting part 100 and the outer wall surface of the abutting part 300 is the shortest. The end point of the line between the positions where the distance between the two is the shortest is located on the outer wall surface of the second shell 11 as the third reference point K3. If the outer wall surface of the sound-emitting part 100 and the outer wall surface of the abutting part 300 abut each other in the natural state, the length of the shortest line between the outer wall surface of the sound-emitting part 100 and the outer wall surface of the abutting part 300 is nearly 0 at this time, and the third reference point K3 should be the midpoint of the arc formed by the abutting area where the outer wall surface of the sound-emitting part 100 and the outer wall surface of the abutting part 300 abut each other.

[0114] In the worn state, the symmetry plane A1 is nearly parallel to the horizontal plane of the human body. In the symmetry plane A1, the ear hook 200, the sound-emitting part 100 and the abutment part 300 have an inner contour, wherein the inner contour includes at least a fourth reference point K4. The fourth reference point K4 is a reference point in the inner contour that is the farthest from the third reference point K3. In the worn state, the fourth reference point K4 is a reference point located on the inner contour of the ear hook 200 and corresponding to the edge of the helix E17 (e.g., the topmost / outermost edge of the helix E17), and the fourth reference point K4 can be a turning point of the inner contour, for example, the inner contour is a contour line that protrudes away from the helix E17 as a whole, and the curvature radius of the part of the inner contour located in the vicinity of the edge of the helix E17 gradually increases, then gradually decreases, and then gradually increases again, starting from the fourth reference point K4, toward the sound-emitting part 100 and the abutment part 300. The fifth reference point K5 is the position point of the sound-emitting part 100 that is farthest from the fourth reference point K4.

[0115] By arranging the first sound output end 102 and the sound input end 101 of the second sound input hole 1101 on both sides of the fifth reference point K5, the second shell 11 protruding between the first sound output end 102 and the sound input end 101 of the second sound input hole 1101 can isolate the sound transmitted from the first sound output end 102, effectively reducing the possibility of the sound transmitted from the first sound output end 102 being introduced into the second sound input hole 1101, which is beneficial to improving the sound reception effect of the earphone 1.

[0116] Alternatively, if Fig. 9 As shown, there is a fourth shortest straight line segment L10 between the hole edge of the sound input end 101 of the second sound input hole 1101 and the fifth reference point K5, and the ratio of the length of the fourth shortest straight line segment L10 to the length of the first shortest straight line segment L6 is between 0.71 and 0.96, for example, it can be 0.75, 0.80, 0.85, 0.90, 0.95, etc., and of course it can also be other values.

[0117] By setting the ratio of the length of the fourth shortest straight line segment L10 to the length of the first shortest straight line segment L6 to be between 0.71 and 0.96, the position of the sound input end 101 of the second sound input hole 1101 relative to the fifth reference point K5 can be reasonably set, thereby reducing the possibility of the sound transmitted from the sound output hole 1102 being introduced into the second sound input hole 1101, which is beneficial to improving the sound reception effect of the earphone 1.

[0118] In some embodiments, Fig.14 and Fig.15As shown, the sound-emitting part 100 includes a shell, a microphone and a sound-emitting component 13 arranged in the shell, wherein the shell may be the aforementioned second shell 11, and the microphone may be the aforementioned second microphone 12. The sound-emitting component 13 has at least one diaphragm 131, and the sound-emitting component 13 cooperates with the second shell 11 to form a first acoustic cavity 1301 and a second acoustic cavity 1302 located on both sides of the diaphragm 131. The second shell 11 is provided with a sound inlet hole, a sound outlet hole 1102 and a pressure relief hole 1103, wherein the sound inlet hole may be the aforementioned second sound inlet hole 1101, and the second microphone 12 collects external sound through the second sound inlet hole 1101, and the sound in the first acoustic cavity 1301 is transmitted to the user's ear canal through the sound outlet hole 1102, and the sound in the second acoustic cavity 1302 is transmitted to the outside of the second shell 11 through the pressure relief hole 1103. Specifically, the first acoustic cavity 1301 is a place where the diaphragm 131 vibrates to push the air to form sound waves for the user to listen to, and the second acoustic cavity 1302 is connected to the pressure relief hole 1103 and then to the outside world, for balancing the air pressure inside the second shell 11. The second sound inlet 1101 and the pressure relief hole 1103 are respectively arranged adjacent to the ear hook 200, and the sound outlet 1102 is arranged away from the ear hook 200 compared with the second sound inlet 1101 and the pressure relief hole 1103. The second sound inlet 1101 has a sound inlet end 101 located on the outer wall surface of the second shell 11, and the pressure relief hole 1103 has a sound outlet end 104 located on the outer wall surface of the second shell 11. There is a shortest straight line segment between the hole edge of the sound inlet end 101 of the second sound inlet 1101 and the hole edge of the sound outlet end 104 of the pressure relief hole 1103, which is called the fifth shortest straight line segment L12. The length of the fifth shortest straight line segment L12 is less than or equal to 4 mm, for example, it can be 1 mm, 2 mm, 3 mm, 3.5 mm, etc., and of course it can also be other values. The ear hook 200 is further configured to block the sound of the pressure relief hole 1103 from being transmitted to the second sound inlet 1101.

[0119] By arranging the second sound inlet 1101 and the pressure relief hole 1103 adjacent to the ear hook 200, the sound outlet 1102 is arranged relatively far away from the ear hook 200, and the length of the fifth shortest straight line segment L12 is set to be less than or equal to 4 mm, so that the sound outlet 1102 is kept at a large distance from the second sound inlet 1101 and the pressure relief hole 1103, respectively, effectively reducing the possibility that the sound outlet 1102 transmits sound outward to interfere with the second sound inlet 1101 and the pressure relief hole 1103. In addition, the ear hook 200 can also provide a certain isolation between the second sound inlet 1101 and the pressure relief hole 1103, thereby effectively reducing the interference between the pressure relief hole 1103 and the second sound inlet 1101, effectively improving the reliability of the earphone 1, and helping to improve the sound reception effect of the earphone 1.

[0120] Alternatively, if Fig.16As shown, the ear hook 200 forms a connection area 201 on the second shell 11, and the sound input end 101 of the second sound input hole 1101 and the sound output end 104 of the pressure relief hole 1103 are arranged on two sides of the connection area 201 that are away from each other, or, as shown in FIG. Figure 6 As shown, the second shell 11 includes a main body 111 and a connecting portion 112 , the connecting portion 112 connects the main body 111 and the ear hook 200 , and the sound input end 101 of the second sound input hole 1101 and the sound output end 104 of the pressure relief hole 1103 are arranged on two sides of the connecting portion 112 that are away from each other.

[0121] By arranging the sound input end 101 of the second sound input hole 1101 and the sound output end 104 of the pressure relief hole 1103 on opposite sides of the connecting area 201 or the connecting portion 112, the second sound input hole 1101 and the pressure relief hole 1103 are isolated by utilizing the connecting area 201 or the connecting portion 112, thereby effectively reducing the possibility of mutual interference between the pressure relief hole 1103 and the second sound input hole 1101, effectively reducing the possibility of sound transmitted by the pressure relief hole 1103 being introduced into the second sound input hole 1101, and effectively reducing the possibility of sound leakage, echo and the like, thereby helping to improve the sound reception effect of the earphone 1.

[0122] Alternatively, if Figure 6 As shown, in the wearing state, the second sound inlet 1101 is arranged on the side of the connecting area 201 or the connecting part 112 away from the helix, and the pressure relief hole 1103 is arranged on the other side of the connecting position or the connecting part 112 close to the helix.

[0123] By setting the second sound inlet 1101 on the side of the connecting area 201 or the connecting part 112 away from the helix, the user's helix E17 can be prevented from blocking the second sound inlet 1101 when wearing it, thereby affecting the sound introduction into the second sound inlet 1101, which is beneficial to improving the sound reception effect of the earphone 1.

[0124] Alternatively, if Figure 6 As shown, the connection portion 112 is arranged in a tapered shape in the direction away from the main body portion 111, so that the ear hook 200 is smoothly connected to the outer surface of the main body portion 111, so as to improve the aesthetics of the earphone 1. The second microphone 12 is arranged in the connection portion 112, and the second sound inlet 1101 is arranged on the connection portion 112, so as to make full use of the space of the connection portion 112, effectively improve the space utilization rate of the earphone 1, and make the structure of the earphone 1 more compact.

[0125] Alternatively, if Figure 5 As shown, along the width direction F2 of the ear hook 200 , the sound inlet end 101 of the second sound inlet hole 1101 and the sound outlet end 104 of the pressure relief hole 1103 are respectively arranged to at least partially overlap with the ear hook 200 .

[0126] Specifically, the symmetry plane A1 is perpendicular to the width direction F2 of the ear hook 200, and a straight line perpendicular to the symmetry plane A1 and parallel to the width direction F2 of the ear hook 200 is used as a reference line A3. When the ear hook 200 is projected along the symmetry plane A1 to the reference line A3, it has a first projection width S1. When the sound input end 101 of the second sound input hole 1101 is projected along the symmetry plane A1 to the reference line A3, it has a third projection width S3. When the sound output end 104 of the pressure relief hole 1103 is projected along the symmetry plane A1 to the reference line A3, it has a fourth projection width S4. The third projection width S3 and the fourth projection width S4 respectively overlap with the first projection width S1 at least partially, so that the ear hook 200 can form a barrier between the sound input end 101 of the second sound input hole 1101 and the sound output end 104 of the pressure relief hole 1103, thereby effectively reducing the possibility that the sound transmitted by the pressure relief hole 1103 is introduced into the second sound input hole 1101, which is beneficial to improving the sound reception effect of the earphone 1.

[0127] Optionally, the maximum dimension of the overlapping portion of the sound inlet end 101 of the second sound inlet hole 1101 and the ear hook 200 along the width direction F2 of the ear hook 200 is equal to the maximum dimension of the sound inlet end 101 of the second sound inlet hole 1101 along the width direction F2. Figure 5 As shown, the maximum size of the sound input end 101 of the second sound input hole 1101 along the width direction F2, that is, the size of the third projection width S3. The maximum size of the overlapping portion of the sound input end 101 of the second sound input hole 1101 and the ear hook 200 along the width direction F2 of the ear hook 200, that is, the size of the overlapping portion of the third projection width S3 and the first projection width S1. That is to say, in the width direction F2 of the ear hook 200, the sound input end 101 of the second sound input hole 1101 completely overlaps with the ear hook 200, that is, the third projection width S3 is completely covered by the first projection width S1.

[0128] Optionally, the ratio of the maximum dimension of the overlapping portion of the sound outlet end 104 of the pressure relief hole 1103 and the ear hook 200 along the width direction F2 of the ear hook 200 to the maximum dimension of the sound outlet end 104 of the pressure relief hole 1103 along the width direction F2 is greater than or equal to 90%. Figure 5 As shown, the maximum size of the sound outlet end 104 of the pressure relief hole 1103 along the width direction F2, that is, the size of the fourth projection width S4. The maximum size of the overlapping portion of the sound outlet end 104 of the pressure relief hole 1103 and the ear hook 200 along the width direction F2 of the ear hook 200, that is, the size of the overlapping portion of the fourth projection width S4 and the first projection width S1. In other words, the ratio of the size of the overlapping portion of the fourth projection width S4 and the first projection width S1 to the size of the fourth projection width S4 is greater than or equal to 90%. For example, when the first projection width S1 is completely covered by the fourth projection width S4, the ratio between the first projection width S1 and the fourth projection width S4 is greater than or equal to 90%.

[0129] In this way, the ear hook 200 can better form a barrier between the sound input end 101 of the second sound input hole 1101 and the sound output end 104 of the pressure relief hole 1103 , which is beneficial to improving the sound reception effect of the earphone 1 .

[0130] Alternatively, if Figure 5 and Fig.16 As shown, the ear hook 200 has a symmetry plane A1 set along the length direction F1 of the ear hook 200, and the ear hook 200 includes an elastic member 21 and an elastic coating 22 wrapped around the outer periphery of the elastic member 21. At one end of the elastic member 21 close to the sound-emitting part 100, the ear hook 200 further has a reference plane tangent to the elastic member 21 and perpendicular to the symmetry plane A1, and the reference plane is called the third reference plane A4. The sound input end 101 of the second sound input hole 1101 is set on one side of the third reference plane A4, and the sound output end 104 of the pressure relief hole 1103 is set on the other side of the third reference plane A4. The elastic member 21 can be, for example, a titanium sheet, and the material of the elastic coating 22 can be, for example, silicone, rubber, elastic resin, polyurethane material, polydimethylsiloxane, PVC, TPE and other materials to improve wearing comfort.

[0131] By respectively arranging the sound input end 101 of the second sound input hole 1101 and the sound output end 104 of the pressure relief hole 1103 on both sides of the third reference plane A4, the sound input end 101 of the second sound input hole 1101 and the sound output end 104 of the pressure relief hole 1103 are further blocked by the hard shell on both sides of the extended surface of the elastic member 21, thereby further improving the isolation effect between the sound input end 101 of the second sound input hole 1101 and the sound output end 104 of the pressure relief hole 1103, which is beneficial to improving the sound reception effect of the earphone 1.

[0132] Alternatively, if Fig.16 As shown, in the wearing state, the second sound inlet 1101 is arranged on the side of the third reference plane A4 away from the helix E17, and the pressure relief hole 1103 is arranged on the other side of the third reference plane A4 close to the helix E17, so that the second sound inlet 1101 can introduce external sound, and the pressure relief hole 1103 has a different orientation from the second sound inlet 1101, and the two are isolated by the hard shell on both sides of the extended surface of the elastic member 21, which effectively reduces the possibility of mutual interference between the second sound inlet 1101 and the pressure relief hole 1103, which is beneficial to improving the sound reception effect of the earphone 1.

[0133] Alternatively, if Fig. 9As shown, on the outer wall of the second shell 11 and the ear hook 200, there is a shortest wall line between the hole edge of the sound input end 101 of the second sound input hole 1101 and the hole edge of the sound output end 104 of the pressure relief hole 1103, and the shortest wall line is called the second shortest wall line L11. The second shortest wall line L11 is specifically the shortest arc segment formed by the hole edge of the sound input end 101 of the second sound input hole 1101 and the hole edge of the sound output end 104 of the pressure relief hole 1103 along the contour line of the outer wall of the second shell 11 and the ear hook 200.

[0134] The arc-chord ratio of the second shortest wall line L11 is set to be greater than or equal to 1.7, for example, it can be 1.7, 1.8, 1.9, 2.0, etc., and of course it can also be other values. By setting the arc-chord ratio of the second shortest wall line L11 to be greater than or equal to 1.7, the second shell 11 between the hole edge of the sound input end 101 of the second sound input hole 1101 and the hole edge of the sound output end 104 of the pressure relief hole 1103 is convex, and the convex second shell 11 can further isolate the second sound input hole 1101 and the pressure relief hole 1103, so as to effectively reduce the possibility of mutual interference between the second sound input hole 1101 and the pressure relief hole 1103, which is beneficial to improving the sound reception effect of the earphone 1.

[0135] Alternatively, if Fig.16 As shown, a partition plate 14 is provided in the sound-emitting part 100, the second microphone 12 is provided on a side of the partition plate 14 close to the ear hook 200, and the sound-emitting component 13 is provided on a side of the partition plate 14 away from the ear hook 200. By providing the partition plate 14 to separate the second microphone 12 and the sound-emitting component 13, the interference caused by the sound-emitting component 13 to the second microphone 12 is effectively reduced, which is conducive to improving the sound reception effect of the earphone 1.

[0136] The above descriptions are merely embodiments of the present application and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
