Description

Technical Field

[0001] The present application relates to a headset, belonging to the technical field of audio equipment. Background Art

[0002] The microphone in the earphone with call recording function is set in the cavity inside the earphone shell. Accordingly, a sound pickup hole needs to be opened on the surface of the earphone shell to connect the cavity inside the earphone with the outside, so that sound waves can enter the earphone shell through the sound pickup hole and be received by the microphone and converted into electrical signals.

[0003] Currently, when a user is using an earphone, if the user is moving or in a windy environment, the wind noise generated by the wind will also enter the earphone shell through the sound pickup hole and be received by the microphone. In this way, the noise generated when the user uses the earphone to record a call is relatively large, resulting in poor call recording quality. Utility Model Content

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0055] The microphone in the earphone with call recording function is set in the cavity inside the earphone shell. Accordingly, a sound pickup hole needs to be opened on the surface of the earphone shell to connect the cavity inside the earphone with the outside, so that sound waves can enter the earphone shell through the sound pickup hole and be received by the microphone and converted into electrical signals.

[0056] Currently, when a user is using an earphone, if the user is moving or in a windy environment, the wind noise generated by the wind will also enter the earphone shell through the sound pickup hole and be received by the microphone. In this way, the noise generated when the user uses the earphone to record a call is relatively large, resulting in poor call recording quality.

[0057] In the earphones provided by the present application, the first microphone is arranged in the first microphone cavity of the shell so that the shell can protect the first microphone. The first sound pickup hole is connected to the first microphone cavity, so that the outside of the shell can be connected to the first microphone cavity, and the sound waves outside the shell can enter the first microphone cavity through the first sound pickup hole, so that the sound waves can be received by the first microphone and converted into electrical signals. The first sound pickup hole is opposite to at least a part of the side of the tragus facing the concha cavity, so that at least a part of the tragus can block the first sound pickup hole, so that when the user faces the wind, the tragus can block the wind noise waves from entering the first sound pickup hole to a certain extent, so as to reduce the wind noise when the earphones of the present application are used.

[0058] The earphones provided in this application are described in detail below in conjunction with specific embodiments.

[0059] In order to clearly describe the structure of the earphone provided by the present application, refer to Figure 1 to Figure 2 As shown, the structure of the ear and the wearing state involved in the text, the front side, back side, upper side, lower side of the ear 200, the human body's sagittal plane, coronal plane, horizontal plane, sagittal axis, coronal axis, vertical axis, and definitions of X, Y, and Z directions will be explained below.

[0060] The ear 200 of the user may include structures such as a helix 210, a suprastragal notch 211, a concha 220, a tragus 230, an antitragus 240, an antihelix 250, an antihelix crus 251, an antihelix crus 252, a triangular fossa 260, a helix crus 270, an ear canal opening 280, and an earlobe 290. The concha 220 may include a cymba concha 222 and a cavum concha 221.

[0061] The front side and the back side of the ear 200 are defined as follows: the “front side of the ear 200” mentioned in this application is a concept relative to the “back side of the ear 200”, the former refers to the side of the ear 200 away from the head, and the latter refers to the side of the ear 200 facing the head, the “upper edge of the ear 200” refers to the outer edge of the helix 210 of the ear 200 facing upward, and the “lower edge of the ear 200” refers to the outer edge of the helix 210 of the ear 200 facing downward, and they are all for the user's ear 200.

[0062] The sagittal plane, coronal plane, horizontal plane, sagittal axis, coronal axis, and vertical axis of the human body are defined as follows: As is well known, in the fields of medicine and anatomy, three basic planes of the human body, namely the sagittal plane, coronal plane, and horizontal plane, and three basic axes, namely the sagittal axis, coronal axis, and vertical axis, can be defined. 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. Accordingly, the sagittal axis refers to an axis perpendicular to the coronal plane along the front-back direction of the body, the coronal axis refers to an axis perpendicular to the sagittal plane along the left-right direction of the body, and the vertical axis refers to an axis perpendicular to the horizontal plane along the up-down direction of the body.

[0063] The definitions of the X, Y, and Z directions are as follows: a coordinate system is established with the center of the ear canal opening as the origin. The direction pointing to the back of the ear and parallel to the sagittal axis is defined as the positive direction of the X-axis; the direction pointing to the outside of the ear and parallel to the coronal axis is defined as the positive direction of the Y-axis; the direction pointing to the top of the ear and parallel to the vertical axis is defined as the positive direction of the Z-axis. It should be noted that the above direction definitions are only for the convenience of description. In accordance with the principles of the present technical solution, the X, Y, and Z directions can be arbitrarily defined, including but not limited to the axial symmetry, angular symmetry, and other definitions of the above orientations.

[0064] The present application embodiment provides a headset, referring to Figures 1 to 4 As shown, the earphone includes a main body 110, an extension 120 and a sound-generating part 130. One end of the main body 110 is connected to the extension 120, that is, one end of the main body 110 is a connecting end, and the other end is a free end, and the connecting end of the main body 110 is used to connect with the extension 120. Among them, the main body 110 is used to be hung on the back side of the ear 200, and can be balanced with the extension 120, so that the earphone can be better worn on the ear 200; in the wearing state, the free end of the main body 110 can also be against the back side of the ear, such as the ear root, the earlobe 290, the head position behind the ear root, etc., so as to support the wearing of the earphone and facilitate the earphone to be stably worn on the ear. In some embodiments, the free end of the main body 110 can be provided with a battery for powering the earphone, and can also be provided with an antenna, Bluetooth and other electronic components for communicating with other devices.

[0065] For the convenience of description, the part with the smallest cross-sectional area on the earphone can be used as the boundary, in other words, the thinnest part on the earphone along the direction of the earphone can be used as the boundary to divide the main body 110 and the extension part 120; in some embodiments, in the wearing state, the ear root contact area 212 on the earphone that contacts the ear root can also be used as the boundary to divide the extension part 120 and the main body 110. In short, in the wearing state, the main body 110 is mainly located at the rear side of the ear 200, and the extension part 120 is mainly located at the front side of the ear 200, so that the earphone can be hung on the helix 210 of the ear 200.

[0066] When worn, the end of the main body 110 away from the extension portion 120 extends downward along the back side of the ear 200 , and the end of the extension portion 120 away from the main body 110 bypasses the top of the helix 210 of the ear 200 , passes through the suprasternal notch 211 , and extends toward the concha cavity 221 of the ear 200 .

[0067] The sound-emitting portion 130 is connected to the end of the extension portion 120 away from the main body 110. In some embodiments, the sound-emitting portion 130 can be a cube, a cuboid, a cylinder, an ellipsoid, a cone, or other regular or irregular three-dimensional structures. Correspondingly, the sound-emitting portion 130 can have a projection of a corresponding shape on the sagittal plane. For example, the projection shape of the sound-emitting portion 130 can be a square, a rectangle, a circle, an ellipse, a rounded rectangle, a racetrack, or other regular or irregular shapes. It is easy to understand that this is related to the outer peripheral surface of the sound-emitting portion 130.

[0068] The earphone of the present application further includes a housing 100 and a first microphone 300, wherein the housing 100 is the outer shell of the earphone as a whole, and the housing 100 is the basic component of the earphone of the present application, and the housing 100 can provide a mounting base for at least some of the other components of the earphone, and serves the purpose of protecting at least some of the other components. The outer shell of the main body 110, the outer shell of the extension part 120, and the outer shell of the sound-emitting part 130 are sequentially connected and constitute the housing 100 of the earphone. The housing 100 can be formed in one step by an injection molding process to form the outer shell of the main body 110, the outer shell of the extension part 120, and the outer shell of the sound-emitting part 130. Of course, the outer shell of the main body 110, the outer shell of the extension part 120, and the outer shell of the sound-emitting part 130 can also be prepared and formed separately and then connected by a connection process to form the housing 100. The present application does not limit the preparation and molding process of the housing 100.

[0069] The housing 100 can be made of metal material, so that the housing 100 has better structural strength, thereby making the durability and reliability of the housing 100 better. Of course, the housing 100 can also be made of polymer material, so that the housing 100 has a certain structural strength and is relatively light. This application does not limit the specific material of the housing 100.

[0070] refer to Figures 2 to 6 As shown, the housing 100 is provided with a first sound pickup hole 121 and a first microphone cavity 122, and the first sound pickup hole 121 is connected to the first microphone cavity 122. Among them, the first microphone cavity 122 is located inside the housing 100, the first sound pickup hole 121 is opened on the surface of the housing 100, and one end of the first sound pickup hole 121 is connected to one end of the first microphone cavity 122, so that the outside of the housing 100 can be connected to the first microphone cavity 122 through the first sound pickup hole 121. The first microphone 300 is arranged in the first microphone cavity 122 of the housing 100, so that the first microphone 300 can be located in the housing 100 as a whole, so that the housing 100 can protect the first microphone 300. Sound waves outside the housing 100 can enter the first microphone cavity 122 through the first sound pickup hole 121, so that the sound waves are received by the first microphone 300 and converted into electrical signals. Specifically, when a user uses the headset of the present application to make a call or record a sound, the sound emitted by the user can enter the first microphone cavity 122 through the first sound pickup hole 121, so that the sound emitted by the user is received by the first microphone 300 and converted into an electrical signal.

[0071] It should be noted that the volume of the first microphone cavity 122 of the shell 100 can be set to be larger than the volume of the first microphone 300, so that when the first microphone 300 is set in the first microphone cavity 122, there is a certain gap between the first microphone 300 and the inner wall of the first microphone cavity 122, so that the sound can be better received by the first microphone 300.

[0072] When the earphone of the present application is worn on the ear, the first sound pickup hole 121 of the housing 100 is opposite to at least a part of the area on the side of the tragus 230 of the ear facing the concha cavity 221, so that part of the tragus 230 can block the first sound pickup hole 121 of the housing 100. Specifically, when the user wears the earphone of the present application facing the wind, the first sound pickup hole 121 is located on the side of the tragus 230 facing away from the windward side, and the tragus 230 can block at least part of the wind noise, so that the energy of the wind noise wave entering the first microphone cavity 122 through the first sound pickup hole 121 of the housing 100 is relatively low. Correspondingly, the energy of the wind noise wave entering the first microphone cavity 122 and received by the first microphone 300 is also relatively low, thereby reducing the wind noise of the earphone of the present application during call recording and improving the signal-to-noise ratio of the earphone.

[0073] In some embodiments, reference Figure 4 and Figure 8As shown, the shape of the extension portion 120 can be a rectangular parallelepiped, a cylinder, a cone, or other regular or irregular strip-shaped three-dimensional structures. For ease of description, the structure of the extension portion 120 can be defined as follows. The extension portion 120 can include an outer surface 120a of the extension portion 120, an inner surface 120b of the extension portion 120, an outer side surface 120d of the extension portion 120, and an inner side surface 120c of the extension portion 120; in addition, the direction from the outer surface 120a to the inner surface 120b can be the thickness direction of the extension portion 120, and the direction from the outer side surface 120d to the inner side surface 120c can be the short axis direction of the extension portion 120, that is, the width direction of the extension portion 120; the direction from the end of the extension portion 120 connected to the main body portion 110 to the end of the extension portion 120 connected to the sound-emitting portion 130 can be the long axis direction of the extension portion 120, that is, the length direction of the extension portion 120.

[0074] The sound-emitting portion 130 is connected to the end of the extension portion 120 facing away from the main body portion 110. The sound-emitting portion 130 can be arranged on the inner surface 120b of the extension portion 120. In other words, when worn, the sound-emitting portion 130 is located on the side of the extension portion 120 facing the concha cavity 221. With this arrangement, the sound-emitting portion 130 will be close to the ear canal opening 280, which is beneficial to improving the sound quality of the earphone.

[0075] In some embodiments, reference Figure 4 As shown, the sound-emitting portion 130 is convexly arranged on the inner surface 120b of the extension portion, and the sound-emitting portion 130 and the extension portion 120 are stacked in the direction of the human coronal axis. In this way, the sound-emitting portion 130 and the extension portion 120 are stacked in the Y-axis direction. In the wearing state, at least a portion of the inner surface 120b of the extension portion 120 is higher than the supra-tragus notch 211 in the Y-axis direction, and at least a portion of the sound-emitting portion (130) is located inside the tragus (230), that is, at least a portion of the sound-emitting portion 130 can be lower than the tragus 230 in the Y-axis direction. Therefore, the sound-emitting portion 130 can extend into the concha cavity 221, and the sound-emitting portion 130 is closer to the ear canal opening 280 than the extension portion 120, so that the sound of the earphone can enter the ear canal opening 280 more easily, thereby improving the sound quality of the earphone; in addition, since the sound-emitting portion 1 The extension portion 120 includes a speaker, and the size of the speaker has a great relationship with the sound quality of the earphone. Therefore, compared with the design in which the sound-emitting portion 130 is usually arranged inside the extension portion 120 or the two are basically at the same height, in this embodiment, due to the stacking design of the sound-emitting portion 130 and the extension portion 120 in the Y-axis direction, the short axis of the extension portion 120 can be set narrower, and the sound-emitting portion 130 can still have a large enough volume to accommodate a larger speaker. In this way, the narrower extension portion 120 can reduce the squeezing of the auricle 240, the antihelix 250 and other areas, and it is also more beautiful; at the same time, the earphone can still have a good sound quality.

[0076] In some embodiments, reference Figure 4 As shown, the first sound pickup hole 121 on the housing 100 in the present application can be set at one of the outer wall of the sound-emitting portion 130, the outer wall of the extension portion 120, and the transition surface between the sound-emitting portion 130 and the extension portion 120. As a result, the first sound pickup hole 121 is relatively closer to the user's mouth 500 when it can be blocked by the tragus 230 facing the side of the cavum concha 221, so that the sound emitted by the user can more easily enter the first sound pickup hole 121 and be received by the first microphone 300.

[0077] Specifically, when the first sound pickup hole 121 is arranged on the outer wall of the sound-emitting part 130, the first sound pickup hole 121 can be located on the outer wall of the sound-emitting part 130 facing the tragus 230, thereby preventing the first sound pickup hole 121 from being blocked by the inner wall of the concha cavity 221, so that the sound emitted by the user can more easily enter the first sound pickup hole 121 and be received by the first microphone 300, thereby making the earphones of the present application have a good sound pickup effect.

[0078] When the first sound pickup hole 121 is disposed on the outer wall of the extension portion 120, the first sound pickup hole 121 can be located on the outer wall of the extension portion 120 facing the tragus 230, that is, located on the inner side surface 120c of the extension portion 120. The first sound pickup hole 121 is not disposed on the inner surface 120b of the extension portion 120, so that the first sound pickup hole 121 will not be blocked by the inner surface of the concha cavity 221, so that the sound emitted by the user can more easily enter the first sound pickup hole 121 and be received by the first microphone 300, thereby making the earphone of the present application have a good sound pickup effect. The first sound pickup hole 121 is not disposed on the outer surface 120a of the extension portion 120, which can prevent the first sound pickup hole 121 from being completely exposed outside the ear 200, thereby preventing dust and impurities from entering the first sound pickup hole 121 to a certain extent, and preventing wind noise in the direction of the coronal axis of the human body from entering the first sound pickup hole 121 to a certain extent, so that the earphone of the present application has a good sound pickup effect.

[0079] It should be understood that the transition surface between the extension part 120 and the sound-emitting part 130 is a curved surface structure connecting the outer shell of the extension part 120 and the outer shell of the sound-emitting part 130. By setting the transition surface, the connection between the outer shell of the extension part 120 and the outer shell of the sound-emitting part 130 can be made smoother, thereby improving the wearing comfort of the earphones of the present application.

[0080] When the first sound pickup hole 121 is set on the transition surface, the first sound pickup hole 121 is located on the area of ​​the transition surface facing the tragus 230, thereby making the distance between the first sound pickup hole 121 and the user's mouth 500 smaller, so that the first microphone 300 can better receive the sound emitted by the user.

[0081] refer to Figure 4As shown, in the embodiment of the present application, the first sound pickup hole 121 can be opened on the inner side of the extension part 120, and the first microphone cavity 122 can be arranged in the extension part 120. Thus, the relatively large outer surface area and relatively large internal space of the extension part 120 can be fully utilized, making the earphone structure layout of the present application more reasonable.

[0082] In some embodiments, reference Figure 7 As shown, when the earphone of the present application is worn on the ear 200 of the user, in the coronal axis direction of the user's body, the height of the first sound pickup hole 121 is lower than the height of the tragus 230. As a result, the first sound pickup hole 121 can be completely blocked by the tragus 230 of the user, so that when the user faces the wind, the tragus 230 can fully block the wind noise waves, so as to further reduce the wind noise sound wave energy entering the first microphone cavity 122, thereby further improving the signal-to-noise ratio of the earphone of the present application.

[0083] In some embodiments, the first sound pickup hole 121 in the present application is spaced apart from a preset plane, wherein the preset plane is parallel to the sagittal plane of the ear and is a plane passing through the highest point of the tragus 230 in the coronal axis direction, the preset plane is indicated by the S plane marked in the figure, and the distance between the first sound pickup hole 121 and the preset plane is indicated by L1 in the figure. The first sound pickup hole 121 is spaced apart from the preset plane by L1, so that the tragus 230 can completely block the first sound pickup hole 121, so that when the user faces the wind, the tragus 230 can fully block the wind noise waves, so as to further reduce the wind noise sound wave energy entering the first microphone cavity 122, thereby further improving the signal-to-noise ratio of the earphone of the present application.

[0084] In some embodiments, reference Figure 7 As shown, the spacing between the first sound pickup hole 121 of the present application and the preset plane is greater than 1.5 mm. It should be understood that when the wind noise wave propagates toward the user's tragus 230, part of the wind noise wave may also fluctuate in the direction biased to the sagittal plane when passing the end of the tragus 230. By making the first sound pickup hole 121 have a spacing greater than 1.5 mm with the preset plane, the first sound pickup hole 121 can have a larger spacing with the preset plane, so that even if some wind noise waves fluctuate, this part of the wind noise sound waves can be fully avoided from entering the first sound pickup hole 121, so that the purpose of the tragus 230 to block wind noise can be further exerted, so that the call recording quality of the headset of the present application is higher.

[0085] In some embodiments, reference Figure 3 , Figure 5 and Figure 6The first microphone cavity 122 of the present application is shown to be located on the side of the first sound pickup hole 121 away from the tragus 230. Therefore, the distance between the first microphone cavity 122 and the tragus 230 is larger than the distance between the first sound pickup hole 121 and the tragus 230, and the first microphone cavity 122 can make full use of the space on the side of the housing 100 away from the tragus 230, making the internal structure layout of the earphone more reasonable.

[0086] In some embodiments, reference Figure 5 As shown, the shell 100 of the present application also has a sound guide channel 124, and the first sound pickup hole 121 is connected to the first microphone cavity 122 through the sound guide channel 124. When the user wears the headset of the present application and is in a moving state, or in a windy environment, the wind noise generated by the wind outside the shell 100 passes through the first sound pickup hole 121 and then passes through the sound guide channel 124 to enter the first microphone cavity 122, which can extend the path of the wind noise wave to reach the first microphone cavity 122. In the process of the wind noise wave passing through the sound guide channel 124, the energy of the wind noise wave itself can be gradually consumed, so that the wind noise energy that finally enters the first microphone cavity 122 is relatively low, so that the wind noise received by the first microphone 300 is relatively small, so that the wind noise generated by the headset of the present application during the call recording process is also small, so that the headset has a better call recording effect.

[0087] In addition, when the wind noise wave passes through the sound guide channel 124 of the shell 100, the wind noise wave will also contact the inner wall of the sound guide channel 124. In this way, the wind noise wave further consumes the energy of the wind noise in the process of colliding and contacting the inner wall of the sound guide channel 124, thereby reducing the wind noise entering the first microphone cavity 122.

[0088] The size of the opening of the first sound pickup hole 121 on the shell 100 can be determined according to the design requirements of the earphone. It should be understood that the larger the aperture of the first sound pickup hole 121 of the shell 100, the stronger the sound wave energy that can enter the shell 100 through the first sound pickup hole 121, thereby enabling the earphone to have a better sound pickup effect.

[0089] The sound guide channel 124 of the present application can be specifically arranged in the extension part 120. Thus, the relatively large internal space in the extension part 120 can be utilized, making it more convenient to arrange the sound guide channel 124 in the shell 100 and making the structure of the earphone of the present application more reasonable and compact.

[0090] In some embodiments, reference Figure 5 to Figure 6As shown, the housing 100 of the present application is further provided with a second sound pickup hole 123, and the two ends of the second sound pickup hole 123 can be respectively connected to the sound guide channel 124 and the first microphone cavity 122. Specifically, the second sound pickup hole 123 is a hole structure opened on the physical structure in the housing 100, and the two ends of the second sound pickup hole 123 are respectively located on the inner wall of the sound guide channel 124 and the inner wall of the first microphone cavity 122.

[0091] At least part of the sound guide channel 124 is arranged at an angle to the line connecting the first sound pickup hole 121 and the second sound pickup hole 123. It should be understood that the line connecting the first sound pickup hole 121 and the second sound pickup hole 123 is a straight line, and at least part of the sound guide channel 124 is arranged at an angle to the line connecting the first sound pickup hole 121 and the second sound pickup hole 123, so that the sound guide channel 124 is a curved channel structure or a bent channel structure.

[0092] It should be understood that if the sound guide channel 124 is a straight channel, then the sound guide channel 124 is the shortest channel path connecting the first sound pickup hole 121 and the second sound pickup hole 123, and the sound guide channel 124 is a curved channel structure or a bent channel structure that can increase the path of the sound guide channel 124, so that the path of the wind noise wave when passing through the sound guide channel 124 can be longer, so that the energy of the wind noise wave can be further consumed in the process of passing through the sound guide channel 124, so as to further reduce the energy of the wind noise wave that finally reaches the first microphone cavity 122, so that the wind noise of the headset of the present application is further reduced when recording a call.

[0093] In addition, it should be understood that the sound guide channel 124 in the present application is a curved or bent channel, so that at least part of the inner wall of the sound guide channel 124 is set at an angle to the direction of the first sound pickup hole 121. In this way, when the wind noise wave enters the sound guide channel 124 through the first sound pickup hole 121, the propagation direction of at least part of the wind noise wave can be toward the inner wall of the sound guide channel 124, so that the wind noise wave is in more complete contact with the inner wall of the sound guide channel 124, so that the energy of the wind noise wave can be further fully consumed, so as to further reduce the wind noise energy that finally reaches the first microphone cavity 122.

[0094] In some embodiments, reference Figure 5As shown, the sound guide channel 124 in the housing 100 in the present application may include a first channel section 124a, a second channel section 124b and a third channel section 124c connected to each other. The first channel section 124a, the second channel section 124b and the third channel section 124c are connected in sequence, wherein the end of the first channel section 124a away from the second channel section 124b is connected to the first sound pickup hole 121, and the end of the third channel section 124c away from the second channel section 124b is connected to the first microphone cavity 122 through the second sound pickup hole 123. The first channel section 124a and the third channel section 124c are both arranged at an angle to the second channel section 124b, so that the extension direction of the first channel section 124a and the extension direction of the third channel section 124c are different from the extension direction of the second channel section 124b, so that the path of the sound guide channel 124 can be increased.

[0095] In addition, when the wind noise wave propagates in the sound guide channel 124, the direction of the wind noise wave can be changed after the wind noise wave enters the second channel section 124b from the first channel section 124a, and the direction of the wind noise wave can be changed again after the wind noise wave enters the third channel section 124c from the second channel section 124b, so as to achieve the purpose of allowing the wind noise wave to fully contact the inner walls of the second channel section 124b and the third channel section 124c to consume the energy of the wind noise wave.

[0096] In addition, in other embodiments, the sound guide channel 124 in the shell 100 in the present application may also include a larger number of channel segments, and adjacent channel segments in each channel segment may be set at an angle, so that the path length of the sound guide channel 124 can be further increased.

[0097] In some embodiments, reference Figure 5 As shown, in the present application, part of the sound guide channel 124 of the housing 100 is bent in the direction away from the line connecting the first sound pickup hole 121 and the second sound pickup hole 123, so that the distance between this part of the sound guide channel 124 and the line connecting the first sound pickup hole 121 and the second sound pickup hole 123 can be relatively large. Part of the sound guide channel 124 is bent in the direction toward the line connecting the first sound pickup hole 121 and the second sound pickup hole 123, so that the distance between this part of the sound guide channel 124 and the line connecting the first sound pickup hole 121 and the second sound pickup hole 123 can be relatively small.

[0098] It should be understood that if the sound guide channel 124 is bent as a whole along the direction of the line connecting the first sound pickup hole 121 and the second sound pickup hole 123, this will cause the sound guide channel 124 to extend as a whole along the space on one side of the shell 100, thereby resulting in a larger space in the shell 100 occupied by the sound guide channel 124, and accordingly, the space in the shell 100 for installing other components of the earphone will be compressed.

[0099] In the present application, by bending a portion of the sound guide channel 124 in the direction away from the line connecting the first sound pickup hole 121 and the second sound pickup hole 123, and bending another portion of the sound guide channel 124 in the direction toward the line connecting the first sound pickup hole 121 and the second sound pickup hole 123, the sound guide channel 124 as a whole will not bend in the same direction, and the sound guide channel 124 can make full use of the space in the shell 100 adjacent to the line connecting the first sound pickup hole 121 and the second sound pickup hole 123, as well as the space in the shell 100 away from the line connecting the first sound pickup hole 121 and the second sound pickup hole 123, so that the range of the space occupied by the sound guide channel 124 in the shell 100 will not be too large, and the space in the shell 100 for installing other components of the earphone is more sufficient, so that the overall volume of the shell 100 does not need to be set too large, making the earphone structure of the present application compact.

[0100] In addition, in other embodiments, multiple parts of the sound guide channel 124 can also be arranged to be located on opposite sides of the line connecting the first sound pickup hole 121 and the second sound pickup hole 123. In this way, the sound guide channel 124 can make full use of the space on opposite sides of the line connecting the first sound pickup hole 121 and the second sound pickup hole 123 in the shell 100, so that the sound guide channel 124 has a larger bending amplitude and a longer path, and the structure of the earphone is further compact.

[0101] In some embodiments, reference Figure 5 As shown, in the present application, the first sound pickup hole 121 and the second sound pickup hole 123 of the first shell 100 are both facing the inner wall of the sound guide channel 124. Specifically, the orifice of the end of the first sound pickup hole 121 connected to the sound guide channel 124 faces the inner wall of the first channel section 124a, and the orifice of the end of the second sound pickup hole 123 connected to the sound guide channel 124 faces the inner wall of the third channel section 124c. Thus, when the wind noise wave enters the sound guide channel 124 through the first sound pickup hole 121, it needs to turn before it can continue to propagate along the sound guide channel 124, and the wind noise wave needs to turn before it can enter the first microphone cavity 122 from the second sound pickup hole 123. In this process, the wind noise wave can also further contact the inner wall of the sound guide channel 124, so that the energy of the wind noise wave can be further fully consumed, so as to achieve the purpose of further reducing the wind noise of the headset of the present application during call recording.

[0102] In some embodiments, reference Figure 5As shown, the earphone of the present application further includes a baffle 140, wherein a sound guide groove is provided on the inner wall of the housing 100. One end of the sound guide groove has a notch, and the baffle 140 is arranged in the housing 100, and the baffle 140 is blocked in the notch of the sound guide groove, thereby surrounding and forming a sound guide channel 124. Correspondingly, the baffle 140 and the inner wall of the sound guide groove can constitute the inner wall of the sound guide channel 124, and the second sound pickup hole 123 can be provided on the inner wall of the sound guide groove. Of course, it should be understood that the second sound pickup hole 123 can also be provided in the baffle 140b, and the specific setting position of the second sound pickup hole 123 is not limited by the present application. The housing 100 can be prepared by an injection molding process, and the process difficulty of molding the sound guide channel 124 in the housing 100 can be reduced by providing the baffle 140, thereby reducing the preparation cost of the earphone of the present application.

[0103] In some embodiments, the earphone of the present application may also include a windshield (not shown in the figure), which is disposed at least one of the first sound pickup hole 121, the second sound pickup hole 123, and between the first sound pickup hole 121 and the second sound pickup hole 123. Thus, the sound waves that enter the housing 100 through the first sound pickup hole 121 and finally reach the first microphone cavity 122 will all pass through the windshield, so that at least part of the wind noise waves in the sound waves can be filtered by the windshield to reduce the energy of the wind noise waves that finally reach the first microphone cavity 122.

[0104] Specifically, the number of windshields is not limited. When the windshield is disposed at the first sound pickup hole 121, the windshield can be specifically disposed at the opening of the first sound pickup hole 121 on the surface of the housing 100, or disposed in the first sound pickup hole 121. When the windshield is disposed at the second sound pickup hole 123, the windshield can be specifically disposed at the connection between the second sound pickup hole 123 and the first microphone cavity 122, or disposed in the second sound pickup hole 123.

[0105] In the present application, the windshield may be configured to include a first windshield and a second windshield, wherein the first windshield may be disposed at the first sound pickup hole 121, and the second windshield may be disposed at the second sound pickup hole 123. Specifically, the first sound pickup hole 121 may be located between the first sound pickup hole 121 and the sound guide channel 124, so that the first windshield is prevented from being exposed outside the housing 100, and the first windshield can be conveniently installed. The second windshield may be disposed between the second sound pickup hole 123 and the sound guide channel 124, so that the second windshield can be conveniently installed.

[0106] In some embodiments, reference Figure 5 , Figure 8 and Fig. 9As shown, the earphone of the present application may also be provided with a second microphone 400, and the second microphone 400 is arranged in the housing 100. The housing 100 is provided with a third sound pickup hole 125 and a second microphone cavity 126, and the second microphone cavity 126 is located inside the housing 100. The second microphone 400 is arranged in the second microphone cavity 126, so that the second microphone 400 can be located in the housing 100 as a whole, so that the housing 100 can protect the second microphone 400. The third sound pickup hole 125 is provided on the surface of the housing 100, and one end of the third sound pickup hole 125 is connected to the second microphone cavity 126, so that the outside of the housing 100 is connected to the second microphone cavity 126 through the third sound pickup hole 125. Sound waves outside the housing 100 can enter the second microphone cavity 126 through the third sound pickup hole 125, so that the sound waves are received by the second microphone 400 and converted into electrical signals.

[0107] Specifically, when the user uses the headset of the present application to make a call or record a sound, the sound emitted by the user can enter the second microphone cavity 126 through the third sound pickup hole 125, and the sound emitted by the user is received by the second microphone 400 and converted into an electrical signal. In this way, the sound emitted by the user can be received by the first microphone 300 and the second microphone 400 at the same time, so that the sound effect of the user collected by the headset of the present application is better, thereby making the call recording effect of the headset better.

[0108] refer to Figure 3 and Figure 8 As shown, the third sound pickup hole 125 of the housing 100 is located on the side of the second sound pickup hole 123 away from the first sound pickup hole 121, so that the first sound pickup hole 121 and the third sound pickup hole 125 can be distributed on both sides of the second sound pickup hole 123, so that the first sound pickup hole 121 and the third sound pickup hole 125 have a relatively large distance. In this way, when the earphone of the present application is worn on the user's ear, the first microphone 300 and the second microphone 400 can obtain sounds from different parts, so that the call recording effect of the earphone of the present application is better.

[0109] In some embodiments, reference Figure 3 and Figure 8As shown, the first sound pickup hole 121 and the third sound pickup hole 125 of the shell 100 in the present application can be distributed on the outer walls of the shell 100 on opposite sides. Since the first sound pickup hole 121 is opposite to the tragus 230 of the user's ear, the third sound pickup hole 125 is also located on the outer wall of the shell 100 on the side facing away from the tragus 230, so that the first sound pickup hole 121 can be relatively close to the user's mouth 500, and the third sound pickup hole 125 can be relatively far away from the user's mouth 500. In this way, the first microphone 300 in the first microphone cavity 122 can fully acquire the sound emitted by the user, and the second microphone cavity 126 in the second microphone cavity 126 can fully acquire the sound in the environment, and eliminate the sound in the environment through the noise reduction algorithm, so that the earphone of the present application has a good noise reduction effect.

[0110] Specifically, the second microphone cavity 126 can be disposed in the extension portion 120, and correspondingly, the third sound pickup hole 125 is disposed on the surface of the extension portion 120. Specifically, the third sound pickup hole 125 can be disposed on the outer side surface 120d of the extension portion 120, so that when the user faces the wind, the inner side surface 120c of the extension portion 120 can block the wind noise, so that the wind noise does not enter the third sound pickup hole 125. In addition, the third sound pickup hole 125 will not be blocked by the concha cavity 221 of the user, so that the sound emitted by the user obtained by the third sound pickup hole 125 is clearer.

[0111] In some embodiments, reference Fig.10 As shown, the distance between the first sound pickup hole 121 and the second sound pickup hole 123 on the housing 100 in the present application can be set to be greater than 13 mm, so that when the earphone of the present application is a dual-microphone noise reduction earphone, the noise reduction algorithm requirements can be met. Fig.10 Indicated by L2 in .

[0112] In some embodiments, reference Fig.10 As shown, when the earphone of the present application is worn on the ear, the angle between the line connecting the first sound pickup hole 121 and the third sound pickup hole 125 and the line connecting the user's mouth 500 and the third sound pickup hole 125 is less than 13°. Fig.10 The m angle in is represented by .

[0113] In some embodiments, the cross-sectional area of ​​the first sound pickup hole 121, the cross-sectional area of ​​the second sound pickup hole 123, and the cross-sectional area of ​​the third sound pickup hole 125 of the housing 100 are all greater than .mm 2In this way, the cross-sectional area of ​​the first sound pickup hole 121, the second sound pickup hole 123 and the third sound pickup hole 125 can be relatively larger under the premise of meeting the process requirements of opening the first sound pickup hole 121, the second sound pickup hole 123 and the third sound pickup hole 125 on the shell 100, so that the sound that can be obtained by the first microphone 300 and the second microphone 400 is clearer.

[0114] The cross-sectional area of ​​the sound guide channel 124 is greater than .mm 2 The sound emitted by the user can pass through the sound guide channel 124 relatively more clearly and be received by the first microphone 300. In addition, the cross-sectional area of ​​the sound guide channel 124 is set to be greater than .mm 2 The wind noise can be eliminated better when passing through the sound guide channel 124.

[0115] In some embodiments, reference Figure 4 and Figure 8 As shown, the housing 100 in the present application may also be provided with a first sound outlet hole 131 and a second sound outlet hole 127. The first sound outlet hole 131 and the second sound outlet hole 127 are located on opposite sides of the housing 100, and a first speaker and a second speaker may be provided in the housing 100 of the earphone, and the first speaker may be opposite to the first sound outlet hole 131, so that the sound emitted by the first speaker can be output through the first sound outlet hole 131. The second speaker may be opposite to the second sound outlet hole 127, so that the sound emitted by the second speaker can be output through the second sound outlet hole 127.

[0116] Specifically, the first sound outlet 131 can be provided on the sound-emitting portion 130 and located on the side of the sound-emitting portion 130 facing the inner wall of the concha cavity 221, and the first sound outlet 131 can also be close to the ear canal opening 280, so that the sound emitted by the first speaker can pass more easily, making the sound heard by the user when wearing the earphone of the present application clearer. The second sound outlet 127 can be provided on the extension portion 120 and located on the outer side 120d of the extension portion 120, thereby, the first sound outlet 131 and the second sound outlet 127 can be distributed on opposite sides of the housing 100.

[0117] The first sound outlet hole 131 is adjacent to the first sound pickup hole 121 , and the second sound outlet hole 127 is adjacent to the third sound pickup hole 125 .

[0118] Finally, it should be noted that the above implementation modes are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned implementation modes, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned implementation modes can still be modified, or some or all of the technical features therein can be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the implementation modes of the present application.
