In the present specification, the exemplary description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any suitable manner in any one or more embodiments or examples.

[0033] In the related art, the earphone can be generally used in an outdoor environment. When the user wears the earphone for running or encounters a windy weather, airflow is easy to enter the earphone through the sound pickup hole on the shell and collide with the sound pickup assembly. In this process, if the user answers or makes a call, the earphone is easy to produce distortion and other wind noise problems, which seriously affects the call quality.

[0034] Therefore, the earphone provided in the embodiments of the present application sets a wind blocking piece 3 with a concave surface 31 between the sound pickup hole 12 of the shell 1 and the sound pickup assembly 2. The concave surface 31 is the surface of the wind blocking piece 3 close to the sound pickup hole 12. The opening 211 direction of the concave surface 31 is towards the sound pickup hole 12, so that the concave surface 31 can change the direction of the airflow entering the accommodating cavity 11 through the sound pickup hole 12, slow down the wind speed, and then make the airflow entering the accommodating cavity 11 through the sound pickup hole 12 not directly collide with the sound pickup assembly 2, which is beneficial to reduce the possibility of the earphone producing distortion and other wind noise problems, and then is beneficial to improve the call quality of the earphone.

[0035] The earphone of the present application can be a headphone, Figure 1 Part of the shell 1 of the earphone in an embodiment of the present application is shown. The sound pickup assembly 2 is installed at the position of the sound pickup hole 12 on the inner side of the shell 1 to capture the user's voice. Specifically, please refer to Figure 2 and Figure 3 The earphone includes a shell 1, a sound pickup assembly 2 and a wind blocking piece 3. The material of the shell 1 can be a material with a certain hardness, such as metal or plastic. The sound pickup assembly 2 is used to capture the user's voice and convert the user's voice signal into an electrical signal, which is transmitted to the mainboard of the earphone through a flexible wire and then sent to the receiving party. The material of the wind blocking piece 3 can be a material with a certain hardness, such as metal or plastic. The shell 1 has an accommodating cavity 11 and a sound pickup hole 12. The user's voice can enter the inside of the earphone through the sound pickup hole 12. The accommodating cavity 11 and the sound pickup hole 12 are communicated. The accommodating cavity 11 can be like Figure 3The setting is shown in the inside of the shell 1, to improve the appearance of the shell 1 of the earphone. The pickup assembly 2 and the wind shield 3 are arranged in the receiving cavity 11, and the wind shield 3 is located on the side of the pickup assembly 2 close to the pickup hole 12, so as to form a certain block to the airflow entering the receiving cavity 11 through the pickup hole 12. The surface of the wind shield 3 close to the pickup hole 12 is a concave surface 31, and the opening 211 direction of the concave surface 31 is towards the pickup hole 12, so that the concave surface 31 can change the direction of the airflow entering the receiving cavity 11 through the pickup hole 12, and the direction of the airflow is rotated, the wind speed is slowed down, and the possibility of direct collision of the airflow with the pickup assembly 2 is reduced, which is beneficial to improve the call quality.

[0036] Exemplarily, please refer to Figure 2 and Figure 3 , Figure 3 The airflow entering the receiving cavity 11 through the pickup hole 12 is schematically shown by the dashed line with arrow. When the wind speed is large in the outdoor environment or the user wears the earphone when moving, the user's voice can enter the inside of the earphone through the pickup hole 12 in the process of the user's call, and then be captured by the pickup assembly 2. The airflow is also easy to enter the inside of the earphone through the pickup hole 12. When the airflow enters the inside of the earphone through the pickup hole 12, it is first blocked by the wind shield 3 to weaken the wind speed. As Figure 3 shown, when the airflow hits the concave surface 31 of the wind shield 3, the airflow can be changed in direction, and then the airflow cannot directly hit the pickup assembly 2, reducing the possibility of wind noise problems such as distortion of the earphone.

[0037] Exemplarily, the earphone can be a Bluetooth earphone, a fitness earphone, a wireless earphone, a running earphone, a wired earphone, a sports earphone, a cycling earphone, a noise reduction earphone, an artificial intelligence earphone, a feedback noise reduction earphone, an adaptive earphone, a high-fidelity earphone, a low-distortion earphone, a spatial audio earphone, etc.

[0038] In the embodiment of the present application, a wind shield 3 with a concave surface 31 is arranged between the pickup hole 12 of the shell 1 and the pickup assembly 2. The concave surface 31 is the surface of the wind shield 3 close to the pickup hole 12, and the opening 211 direction of the concave surface 31 is towards the pickup hole 12, so that the concave surface 31 can change the direction of the airflow entering the receiving cavity 11 through the pickup hole 12, slow down the wind speed, and then the airflow entering the receiving cavity 11 through the pickup hole 12 will not directly hit the pickup assembly 2, which is beneficial to reduce the possibility of wind noise problems such as distortion of the earphone, and then improve the call quality of the earphone.

[0039] In an embodiment, please refer to Figure 3, the concave surface 31 comprises a first wind deflector 311 and a second wind deflector 312, the first wind deflector 311 is arranged transversely to the direction of the airflow entering the accommodating cavity 11 through the pickup hole 12, so that the first wind deflector 311 can change the direction of the airflow entering the accommodating cavity 11 through the pickup hole 12. For example, the first wind deflector 311 can be arranged perpendicularly to the direction of the airflow entering the accommodating cavity 11 through the pickup hole 12, so that in the process of the airflow entering the accommodating cavity 11 through the pickup hole 12 colliding with the first wind deflector 311, the airflow can diffuse along the periphery of the first wind deflector 311, thereby slowing down the wind speed of the airflow and reducing the wind pressure of the airflow. The second wind deflector 312 is arranged at an angle with the first wind deflector 311, and the angle between the second wind deflector 312 and the first wind deflector 311 can be an acute angle or an obtuse angle as shown in Figure 3 , the second wind deflector 312 can surround the outer periphery of the first wind deflector 311, and the second wind deflector 312 can also be connected to the preset edge position of the first wind deflector 311, and the number of preset edge positions can be one or more. The second wind deflector 312 is located on the side of the first wind deflector 311 close to the pickup hole 12, so that when the airflow entering the accommodating cavity 11 through the pickup hole 12 diffuses along the periphery of the first wind deflector 311 after colliding with the first wind deflector 311, it can further revolve along the second wind deflector 312 to the external environment, further reducing the possibility of the airflow entering the accommodating cavity 11 through the pickup hole 12 directly colliding with the pickup assembly 2, thereby reducing the possibility of the earphone generating distortion and other wind noise problems, and further improving the call quality of the earphone.

[0040] In an embodiment, please refer to Figure 3 and Figure 4 , the wind deflector 3 has a sound collecting hole 32, so that the user's voice can pass through the sound collecting hole 32 and be captured by the pickup assembly 2. The sound collecting hole 32 is located on the second wind deflector 312, so that the airflow entering the accommodating cavity 11 through the pickup hole 12 cannot directly collide with the pickup assembly 2 through the sound collecting hole 32, thereby reducing the possibility of the airflow entering the accommodating cavity 11 through the pickup hole 12 colliding with the pickup assembly 2 and generating distortion and other wind noise problems. For example, the number of sound collecting holes 32 can be as shown in Figure 3 and Figure 4 , a plurality of sound collecting holes 32 are arranged along the outer periphery of the first wind deflector 311 to improve the volume of the user's voice after passing through the sound collecting hole 32. The sound collecting hole 32 is in communication with the pickup hole 12, so that the user's voice can enter the accommodating cavity 11 through the pickup hole 12, and then pass through the sound collecting hole 32 to be captured by the pickup assembly 2, thereby reducing the influence of the wind deflector 3 on the capture of the user's voice by the pickup assembly 2, and further improving the call quality of the earphone.

[0041] It can be understood that the wind deflector 3 is not limited to having a sound collecting hole 32.

[0042] In an embodiment, referring to Figure 3 The angle between the second wind-blocking surface 312 and the first wind-blocking surface 311 ranges from 0° to 180°, so that the concave surface 31 forms a certain block to the airflow entering the accommodating cavity 11 through the sound pickup hole 12 and rotates the direction of the airflow, slows down the wind speed, reduces the possibility of the airflow directly colliding with the sound pickup assembly 2, and is beneficial to improve the call quality.

[0043] Exemplarily, the angle between the first wind-blocking surface 311 and the second wind-blocking surface 312 can be 0°, 10°, 20°, 30°, 50°, 70°, 80°, 100°, 120°, 140°, 160°, or 180°.

[0044] Exemplarily, when the angle between the first wind-blocking surface 311 and the second wind-blocking surface 312 is 0° or 180°, the concave surface 31 is a plane.

[0045] It can be understood that the range of the angle between the second wind-blocking surface 312 and the first wind-blocking surface 311 is not limited to 0°-180°. Exemplarily, the range of the angle between the second wind-blocking surface 312 and the first wind-blocking surface 311 can also be less than 0° or greater than 180°, so that the concave surface 31 is a convex surface.

[0046] In an embodiment, the angle between the second wind-blocking surface 312 and the first wind-blocking surface 311 ranges from 90° to 150°, so that the concave surface 31 forms a certain block to the airflow entering the accommodating cavity 11 through the sound pickup hole 12 and rotates the direction of the airflow, slows down the wind speed, reduces the possibility of the airflow directly colliding with the sound pickup assembly 2, and is beneficial to improve the call quality.

[0047] Exemplarily, the angle between the first wind-blocking surface 311 and the second wind-blocking surface 312 can be 90°, 100°, 110°, 120°, 130°, 140°, or 150°.

[0048] It can be understood that the range of the angle between the second wind-blocking surface 312 and the first wind-blocking surface 311 is not limited to 90°-150°. Exemplarily, the range of the angle between the second wind-blocking surface 312 and the first wind-blocking surface 311 can also be less than 90° or greater than 150°.

[0049] In an embodiment, a plane perpendicular to the direction of the airflow entering the accommodating cavity 11 through the sound pickup hole 12 is defined as a reference plane, the projection area of the wind-blocking piece 3 on the reference plane is located in the projection area of the sound pickup hole 12 on the reference plane, so that the range of the wind-blocking piece 3 on the reference plane is smaller than the range of the sound pickup hole 12 on the reference plane, so that after the airflow entering the accommodating cavity 11 through the sound pickup hole 12 is changed in direction by the concave surface 31, the airflow can more smoothly rotate again through the sound pickup hole 12 to the external environment, reduces the possibility of the airflow directly colliding with the sound pickup assembly 2 to generate wind noise problems, and is beneficial to improve the call quality.

[0050] It can be understood that the projection area of the wind shield 3 on the reference plane is not limited to being located within the projection area of the sound pickup hole 12 on the reference plane. Exemplarily, the projection area of the sound pickup hole 12 on the reference plane can also be located within the projection area of the wind shield 3 on the reference plane.

[0051] In an embodiment, the projection area of the sound pickup assembly 2 on the reference plane is located within the projection area of the sound pickup hole 12 on the reference plane. It should be noted that when the earphone is used in an outdoor environment or the user wears the earphone during exercise, rainwater or sweat is likely to enter the accommodation cavity 11 through the sound pickup hole 12, and then corrode the sound pickup assembly 2 located in the accommodation cavity 11, thereby reducing the service life of the earphone. Figure 3 The orientation and positional relationship of various components in the earphone when the user normally wears the earphone are shown as follows: Figure 3 As shown, rainwater or sweat is likely to flow into the accommodation cavity 11 through the upper sound pickup hole 12. The range of the sound pickup assembly 2 on the reference plane is smaller than the range of the sound pickup hole 12 on the reference plane, so that the rainwater or sweat that has entered the accommodation cavity 11 can be more easily and timely discharged to the outside of the earphone through the lowermost sound pickup hole 12, thereby reducing the possibility of corrosion of the sound pickup assembly 2 by rainwater or sweat, and being conducive to improving the service life of the earphone.

[0052] It can be understood that the projection area of the sound pickup assembly 2 on the reference plane is not limited to being located within the projection area of the sound pickup hole 12 on the reference plane. Exemplarily, the projection area of the sound pickup hole 12 on the reference plane can also be located within the projection area of the sound pickup assembly 2 on the reference plane.

[0053] In an embodiment, referring to Figure 3 and Figure 4 , the cavity wall of the accommodation cavity 11 has a flow guide groove 13 that is in communication with the sound pickup hole 12, so that the rainwater or sweat that has entered the accommodation cavity 11 can first be collected in the flow guide groove 13, and then discharged to the outside of the earphone through the flow guide groove 13 and the sound pickup hole 12 in communication with the flow guide groove 13, thereby accelerating the speed of the rainwater or sweat being discharged to the outside of the earphone through the sound pickup hole 12, further reducing the possibility of corrosion of the sound pickup assembly 2 by rainwater or sweat, and being conducive to improving the service life of the earphone.

[0054] It can be understood that the cavity wall of the accommodation cavity 11 is not limited to having the flow guide groove 13, and the rainwater or sweat can be directly discharged to the outside of the earphone through the sound pickup hole 12.

[0055] In an embodiment, referring to Figure 3 and Figure 4The pickup assembly 2 comprises a shock-absorbing sleeve and a microphone 22. The shock-absorbing sleeve can be made of a material with elasticity, such as rubber. The microphone 22 is arranged in the shock-absorbing sleeve to reduce the vibration of the microphone 22. The shock-absorbing sleeve has an opening 211 which is in communication with the pickup hole 12, so that the user's voice can pass through the pickup hole 12 and the opening 211 in communication with the pickup hole 12, and then be captured by the microphone 22.

[0056] In an embodiment, referring to Figure 4 The pickup assembly 2 further comprises a tuning net 23. The tuning net 23 can be in the form of a fine mesh. The tuning net 23 can be made of a material with hardness, such as plastic or metal. The tuning net 23 is arranged in the shock-absorbing sleeve and is arranged on the side of the microphone 22 close to the pickup hole 12. The tuning net 23 in the form of a mesh has certain dustproof and waterproof capabilities, so as to reduce the possibility of pollutants polluting the microphone 22, and is beneficial to prolong the service life of the microphone 22. In addition, the wind pressure of the airflow passing through the wind-blocking piece 3 can be further reduced by the tuning net 23 in the form of a mesh, so as to weaken the impact of the airflow on the microphone 22, so that the wind noise of the earphone is smaller, and the possibility of distortion and other wind noise problems of the earphone is reduced, which is beneficial to improve the call quality of the earphone.

[0057] The embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited to the above embodiments.
