[0033] In the description of the present application, the description of the terms "one embodiment", "some embodiments", "exemplary embodiment", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in combination with the embodiment or example are included in at least one embodiment or example of the present application. 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 one or more embodiments or examples in a suitable manner.
[0034] In the related art, in order to be closer to the user's mouth to more accurately capture the user's voice, the sound pickup hole on the earphone shell is usually arranged at the bottom of the shell and the opening direction of the sound pickup hole is usually parallel or coincides with the extension direction of the shell. When the user uses the earphone, if the wind speed of the surrounding environment is large, the airflow blows horizontally through the earphone, and the shell at the position of the sound pickup hole arranged in this form cannot well disperse the wind pressure, and more airflow directly enters the shell, so that the wind noise of the earphone is large, and distortion and other wind noise problems are easily generated, which seriously affects the call quality.
[0035] Therefore, the earphone provided in the embodiments of the present application sets the sound pickup hole 21 in the decompression area 2b of the shell 2 and arranges the opening direction 31 of the sound pickup hole 21 to cross the axial direction of the shell 2, so that the sound pickup hole 21 can be located at the eccentric position of the decompression area 2b, that is, the sound pickup hole 21 can be located at the inclined position of the decompression area 2b along the axial direction of the shell 2. The decompression area 2b is used to disperse the wind power of the airflow, and when the airflow blows horizontally through the earphone, the airflow is easy to flow along the outer surface of the decompression area 2b, so that the horizontal airflow is easy to be dispersed into two small airflows with different directions in the decompression area 2b. The sound pickup hole 21 is located at the eccentric position of the decompression area 2b, the airflow at the position of the sound pickup hole 21 has been dispersed, and the dispersed airflow flows along the surface of the decompression area 2b, which reduces the flow of the airflow entering the inside of the shell 2 through the sound pickup hole 21, so that the wind noise of the earphone is small, the possibility of distortion and other wind noise problems of the earphone is reduced, and the call quality of the earphone is improved.
[0036] Figure 1 The position and state of the earphone worn on the ear 5 in an embodiment of the present application are shown. Specifically, please refer to Figure 2 and Figure 3The earphone comprises an earphone body 1 and a shell 2. The earphone body 1 can emit sound in a wired or wireless manner, so that the earphone body 1 can be used to play audio in the concha cavity for the user to listen to. The shell 2 can be made of a material with a certain hardness, for example, a plastic with a relatively smooth outer surface, so as to improve the comfort of the user when wearing the earphone. The shell 2 is connected with the earphone body 1 to encapsulate the earphone body 1 and provide protection for the earphone body 1. The shell 2 has a sound pickup hole 21 for picking up sound. The sound signal of the user can enter the shell 2 through the sound pickup hole 21 to be converted into an electrical signal and transmitted to the receiving party, so that the earphone can have a call function. The shell 2 has a pressure reduction area 2b for dispersing the wind power of the airflow. It should be noted that the shell 2 in the pressure reduction area 2b can have a circular arc structure, that is, the surface of the pressure reduction area 2b can be curved, so that when the airflow blows through the pressure reduction area, the pressure reduction area with a circular arc structure can disperse the airflow into multiple small airflows to disperse the wind power of the airflow and reduce the wind pressure of the airflow. The sound pickup hole 21 is arranged at the pressure reduction area 2b, and the opening direction of the sound pickup hole 21 is arranged to cross the axial direction of the shell 2, so that the flow of the airflow entering the sound pickup hole 21 is small. For example, the sound pickup hole 21 can be arranged at the chamfered position of the shell.
[0037] Exemplarily, Figure 1 The direction indicated by R1 is the opening direction of the sound pickup hole 21, and the direction indicated by R2 is the axial direction of the shell 2. R1 and R2 are arranged to cross.
[0038] Exemplarily, when the earphone is worn on the ear 5 and the wind speed of the surrounding environment is large, the airflow can blow horizontally through the earphone. When the airflow blows horizontally through the shell 2, the wind pressure of the airflow directly acts on the shell 2, and the wind pressure on the surface of the shell 2 is large. When the airflow blows horizontally through the pressure reduction area 2b, due to the curved characteristics of the arc shape, the airflow can flow along the curved surface of the arc shape, so that the airflow is separated into multiple small airflows, and the wind pressure of each small airflow is also reduced. The sound pickup hole 21 is arranged at the pressure reduction area 2b, and the opening direction of the sound pickup hole 21 is arranged to cross the axial direction of the shell 2, so that the sound pickup hole 21 can avoid the direct action of the airflow, that is, the small airflow flowing along the surface of the pressure reduction area 2b flows through the sound pickup hole 21 of the present application, so as to reduce the flow of the airflow entering the inside of the shell 2 through the sound pickup hole 21.
[0039] 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.
[0040] In the embodiments of the present application, the sound pickup hole 21 is arranged at the decompression area 2b of the shell 2, and the opening 31 of the sound pickup hole 21 is arranged in a direction intersecting the axial direction of the shell 2, so that the sound pickup hole 21 is located at an eccentric position of the decompression area 2b, that is, the sound pickup hole 21 can be located at a diagonal position of the decompression area 2b along the axial direction of the shell 2. When the air flow blows horizontally through the earphone, the air flow is easy to flow along the outer surface of the decompression area 2b, so that the horizontal air flow is easy to be dispersed into a plurality of small air flows with different directions on the decompression area 2b. The sound pickup hole 21 is located at the eccentric position of the decompression area 2b, the air flow at the position of the sound pickup hole 21 has been dispersed, and the dispersed air flow flows along the surface of the decompression area 2b, which reduces the flow rate of the air flow entering the inside of the shell 2 through the sound pickup hole 21, so that the wind noise of the earphone is smaller, and the possibility of the earphone generating distortion and other wind noise problems is reduced, which is beneficial to improve the call quality of the earphone.
[0041] In an embodiment, referring to Figure 1 and Figure 2 , the sound pickup hole 21 is located at one side of the decompression area 2b close to the ear 5, for example, the sound pickup hole 21 is located at the rear of the decompression area 2b relative to the forward direction of the user.
[0042] In the embodiments of the present application, in the case of headwind or rapid forward movement of the user, the wind blows backward relative to the user, please refer to Figure 1 , because the sound pickup hole 21 is located at one side of the decompression area 2b close to the ear 5, the wind can be almost blocked by the surface of the shell 2 except the sound pickup hole 21, which greatly reduces the flow rate of the air flow entering the inside of the shell 2 through the sound pickup hole 21, so that the wind noise of the earphone is smaller, and the possibility of the earphone generating distortion and other wind noise problems is reduced, which is beneficial to improve the call quality of the earphone. In the case of leeward, the wind blows forward relative to the user, when the air flow blows horizontally through the earphone, the air flow is easy to flow along the outer surface of the decompression area 2b, so that the horizontal air flow is easy to be dispersed into a plurality of small air flows with different directions on the decompression area 2b. The sound pickup hole 21 is located at an eccentric position of the decompression area 2b, the air flow at the position of the sound pickup hole 21 has been dispersed, and the dispersed air flow flows along the surface of the decompression area 2b, which reduces the flow rate of the air flow entering the inside of the shell 2 through the sound pickup hole 21, so that the wind noise of the earphone is smaller.
[0043] It can be understood that the sound pickup hole 21 is not limited to being located at one side of the decompression area 2b close to the ear 5. For example, the sound pickup hole 21 can also be located at one side of the decompression area 2b away from the ear 5.
[0044] In an embodiment, the sound pickup hole 21 comprises a plurality of sub-holes, and adjacent two sub-holes are independent of each other, so that when the airflow passes through the sound pickup hole 21 and enters the inside of the shell 2, the wind pressure of the airflow can be further reduced by the plurality of independent sub-holes, so as to reduce the flow of the airflow passing through the sound pickup hole 21 and entering the inside of the shell 2, so that the wind noise of the earphone is smaller, the possibility of distortion and other wind noise problems of the earphone is reduced, and the call quality of the earphone is improved.
[0045] It can be understood that the sound pickup hole 21 is not limited to comprising sub-holes. For example, the sound pickup hole 21 can also be a whole through hole.
[0046] In an embodiment, referring to Figure 2 and Figure 3 , the shell 2 further comprises a flat area 2a, and it should be noted that the surface of the shell 2 in the flat area 2a can be substantially planar. The decompression area 2b is located on the side of the flat area 2a away from the earphone body 1, so that when the earphone is worn on the ear 5, the flat area 2a can be connected with the earphone body 1, and the decompression area 2b is located below the flat area 2a, so that the sound pickup hole 21 can be closer to the mouth 6 of the human body, and the accuracy of the earphone in capturing the user's voice is improved.
[0047] It can be understood that the position relationship between the decompression area 2b and the flat area 2a can not be limited. For example, the decompression area 2b can also be located on the side of the flat area 2a close to the earphone body 1.
[0048] In an embodiment, referring to Figure 1 , when the earphone is worn on the ear 5, the axial direction of the flat area 2a is arranged to intersect the vertical direction, so that the extension line of the flat area 2a in the axial direction can intersect the mouth 6, and then the sound pickup hole 21 located below the flat area 2a can be closer to the mouth 6 of the human body, and the accuracy of the earphone in capturing the user's voice is improved.
[0049] It can be understood that the axial direction of the flat area 2a is not limited to being arranged to intersect the vertical direction. For example, the axial direction of the flat area 2a can also be parallel to the vertical direction.
[0050] In an embodiment, the earphone comprises a microphone, the microphone is arranged in the shell 2, and the microphone has a sound collecting hole, the sound collecting hole is communicated with the sound pickup hole 21, so that the sound signal captured through the sound pickup hole 21 can be transmitted to the microphone, and then the earphone has a call function. Furthermore, the sound pickup hole 21 of the present application can reduce the wind pressure of the airflow entering the shell 2, and then weaken the degree of the airflow colliding with the sound collecting hole of the microphone, so as to reduce the wind noise, and improve the call quality of the earphone.
[0051] In an embodiment, referring to Figure 3The earphone comprises a shock-absorbing pad 3, which can be made of a material with elasticity, such as rubber. The shock-absorbing pad 3 is arranged in the shell 2 and located between the sound collecting hole and the sound pickup hole 21, so as to reduce the vibration of the microphone.
[0052] It can be understood that the earphone is not limited to comprising the shock-absorbing pad 3.
[0053] In an embodiment, referring to Figure 3 The shock-absorbing pad 3 has an opening 31, which is in communication with the sound collecting hole and the sound pickup hole 21 respectively, so that the sound signal can be better transmitted from the sound pickup hole 21 to the sound collecting hole of the microphone.
[0054] Exemplarily, the shock-absorbing pad 3 can have a shock-absorbing cavity, so that the shock-absorbing pad 3 is hollow inside. The opening 31 is in communication with the shock-absorbing cavity, so that the sound pickup hole 21, the opening 31, the shock-absorbing cavity and the sound collecting hole are sequentially communicated.
[0055] It can be understood that the shock-absorbing pad 3 can not be limited to having the opening 31.
[0056] In an embodiment, referring to Figure 3 The earphone comprises a tuning net 4, which can be in the form of a fine mesh. The tuning net 4 can be made of a material with hardness, such as plastic or metal. The tuning net 4 is arranged in the shell 2 and covers the sound pickup hole 21, i.e. the tuning net 4 covers the side of the sound pickup hole 21 close to the microphone. The mesh-shaped tuning net 4 has certain dustproof and waterproof capabilities, so as to reduce the possibility of pollutants entering the shell 2 and polluting the internal structure of the earphone, thereby improving the service life of the earphone. In addition, the wind pressure of the airflow can be further reduced by the mesh-shaped tuning net 4 during the process of the airflow entering the inside of the shell 2 through the sound pickup hole 21, so as to reduce the flow of the airflow entering the inside of the shell 2 through the sound pickup hole 21, so that the wind noise of the earphone is smaller, thereby reducing the possibility of the earphone generating distortion and other wind noise problems, and improving the call quality of the earphone.
[0057] A second aspect of the embodiment of the application provides a playing device, which comprises an earphone and a charging bin. The charging bin is used for accommodating the earphone, so that the user can better store the earphone when the earphone is not used, thereby reducing the possibility of the earphone being lost. In addition, the charging bin can also have a charging function. Exemplarily, the earphone has a charging terminal, and the charging bin has a power supply terminal. When the earphone is located in the charging bin, the power supply terminal of the charging bin can be connected with the charging terminal of the earphone, so as to charge the earphone.
[0058] 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, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present application.
