The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] In the description of the present utility model, it is necessary to understand that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] like Figure 1 As shown, the utility model relates to an earphone, wherein the earphone is a smart earphone, and at the same time, the earphone can be an open earphone, a head-mounted earphone or an in-ear earphone, and the earphone can be a wired earphone or a TWS earphone; wherein the earphone can be configured with a call noise reduction function and / or an artificial intelligence noise reduction function, and at the same time, can also be configured with stereo surround and other functions.

[0034] Combination Figure 2 and Figure 3 The earphone includes a housing 100 , a microphone 200 and a sealing pad 300 .

[0035] The housing 100 is provided with a sound inlet hole 110 and at least two sound inlet channels 120; the sound inlet hole 110 is opened on the inner wall of the housing 100, one end of the at least two sound inlet channels 120 is connected to the end of the sound inlet hole 110 away from the inner wall of the housing 100, the other end of the at least two sound inlet channels 120 passes through the outer surface of the housing 100, and the at least two sound inlet channels 120 are spaced apart along the four sides of the sound inlet hole 110, and in addition, the at least two sound inlet channels 120 are connected to each other.

[0036] It can be understood that the shell 100 is a hollow structure, the sound inlet hole 110 passes through the inner surface of the shell 100, the sound inlet channel 120 passes through the outer surface of the shell 100, and the inner end of each sound inlet channel 120 is connected to the end of the sound inlet hole 110 away from the inner surface of the shell 100. In addition, at least two sound inlet channels 120 are spaced apart along the four sides of the sound inlet hole 110, and the inner ends of at least two sound inlet channels 120 are connected to each other.

[0037] The microphone 200 is disposed inside the housing 100 , and the sound pickup hole of the microphone 200 is disposed opposite to and communicated with an end of the sound inlet hole 110 away from the sound inlet channel 120 .

[0038] It is understandable that when a user wears the earphones of the present invention and walks, or when the wind around the earphones is relatively strong, airflow can enter from one of the sound inlet channels 120 and then flow out from the other sound inlet channel 120, thereby reducing the airflow entering the sound inlet hole 110, and further reducing the pressure at the sound pickup hole of the microphone 200, thereby achieving the purpose of reducing wind noise.

[0039] Specifically in this embodiment, there are two sound inlet channels 120, and the two sound inlet channels 120 are relatively arranged near one end of the sound inlet hole 110. In this way, when the airflow enters from one sound inlet channel 120, it can enter the other sound inlet channel 120 more smoothly and flow out, thereby further achieving the purpose of reducing wind noise.

[0040] It should be noted that the two sound inlet channels 120 are spaced apart from one end of the sound inlet hole 110 along the width direction of the housing 100, and the two sound inlet channels 120 are arranged at an angle to one end of the sound inlet hole 110. In this way, considering the wind direction around the earphone, more airflow will enter one of the sound inlet channels 120 from the outside and flow out through the other sound inlet channel 120.

[0041] Combination Figure 3 and Figure 4 Furthermore, the housing 100 has a wind shield 130 that is spaced apart from and arranged opposite to one end of the sound inlet hole 110 away from the microphone 200, and the sound inlets of at least two sound inlet channels 120 are arranged around the wind shield 130. The wind shield 130 can block the airflow from directly flowing to the sound inlet hole 110 and acting on the microphone 200, thereby reducing wind noise.

[0042] like Figure 3 As shown, one end of the sealing pad 300 abuts against one end of the sound inlet hole 110 close to the microphone 200 , and the other end of the sealing pad 300 abuts against one end of the sound pickup hole of the microphone 200 close to the sound inlet hole 110 .

[0043] It can be understood that the sealing gasket 300 is arranged between the side of the microphone 200 close to the sound inlet hole 110 and the inner wall of the housing 100, and the sealing gasket 300 does not block the channel between the sound inlet hole 110 and the sound pickup hole of the microphone 200. The sealing gasket 300 can play a sealing role, reduce the risk of sound leakage from the gap between the microphone 200 and the inner wall of the housing 100, and improve the call quality.

[0044] The sealing pad 300 may be a rubber pad.

[0045] Combination Figure 3 and Figure 4 In some embodiments, at least two sound input channels 120 each include a first sound input segment 121 and a second sound input segment 122, the second sound input segment 122 is located on a side of the first sound input segment 121 close to the sound input hole 110, and a sound input direction of the first sound input segment 121 is set at an acute angle to a sound input direction of the second sound input segment 122.

[0046] It should be noted that the sound input direction of the first sound input segment 121 refers to the transmission direction of the sound or airflow after the sound or airflow enters the first sound input segment 121 from the outside; the sound input direction of the second sound input segment 122 refers to the transmission direction of the sound or airflow after the sound or airflow enters the second sound input segment 122 from the outside.

[0047] It can be understood that by making the sound input direction of the first sound input section 121 and the sound input direction of the second sound input section 122 form an acute angle, when the external airflow enters the first sound input section 121 and enters the second sound input section 122 from the first sound input section 121, the airflow will hit the side wall of the second sound input section 122 to be decelerated, so that the speed of the airflow entering the sound input hole 110 will be lowered, thereby reducing the pressure at the sound pickup hole of the microphone 200 and reducing wind noise.

[0048] like Figure 5 As shown, specifically, the second sound inlet segment 122 has a windshield 1221 arranged opposite to the outlet of the first sound inlet segment 121, that is, when the external airflow enters the first sound inlet segment 121 and enters the second sound inlet segment 122 from the first sound inlet segment 121, the airflow will hit the windshield 1221 and slow down.

[0049] Furthermore, a tangent direction t of a side of the wind shielding wall 1221 close to the sound inlet hole 110 is arranged at an obtuse angle to the sound intake direction of the sound inlet hole 110 .

[0050] It should be noted that the sound input direction of the sound inlet hole 110 refers to the transmission direction of the sound or airflow entering the sound inlet hole 110 through the sound inlet channel 120 in the sound inlet hole 110. The tangent t of the side of the wind shield 1221 close to the sound inlet hole 110 is set at an obtuse angle to the sound input direction of the sound inlet hole 110, which will cause the airflow of the second sound inlet section 122 to deviate from the sound inlet hole 110, and reduce the airflow entering the sound inlet hole 110 from the second sound inlet section 122, thereby reducing wind noise.

[0051] Combination Figure 3 and Figure 4 In some embodiments, the inner wall of the housing 100 is provided with a mounting groove 140 arranged opposite to the sound inlet hole 110, and at least a portion of the sealing gasket 300 is arranged in the mounting groove 140. The mounting groove 140 is used to position the sealing gasket 300 and provide an installation position for the sealing gasket 300, thereby improving the installation accuracy of the sealing gasket 300.

[0052] Furthermore, the sealing pad 300 has a mesh structure located between the sound inlet hole 110 and the sound pickup hole of the microphone 200 , and the mesh structure can play a role in dust prevention and sound tuning.

[0053] Combination Figure 6 and Figure 7 In some embodiments, two positioning protrusions 150 are connected to the inner wall of the housing 100 . The two positioning protrusions 150 are opposite to each other and spaced apart, and the microphone 200 is located between the two positioning protrusions 150 .

[0054] It is understandable that the positioning protrusion 150 can limit the position of the microphone 200 to ensure the installation accuracy of the microphone 200, thereby ensuring that the sound pickup hole of the microphone 200 is opposite to the sound input hole 110.

[0055] Specifically in this embodiment, two positioning protrusions 150 are arranged at intervals along the width direction of the housing 100 .

[0056] Furthermore, the two sides of the microphone 200 are respectively abutted against the two positioning protrusions 150. In this way, the microphone 200 can be limited. In addition, after the positioning protrusions 150 limit the microphone 200, the microphone 200 and the sealing gasket 300 can be abutted against each other to ensure the sealing performance of the sealing gasket 300.

[0057] It should be noted that the positioning protrusion 150 and the housing 100 are an integral structure and are made of plastic. During the installation of the microphone 200, the microphone 200 can be inserted between the two positioning protrusions 150. After the microphone 200 is inserted between the two positioning protrusions 150, the two positioning protrusions 150 have a clamping effect on the microphone 200, thereby limiting the position of the microphone 200.

[0058] Furthermore, a plurality of glue injection grooves 160 are provided on one side of the positioning protrusion 150 close to the microphone 200 . The plurality of glue injection grooves 160 are arranged at intervals, and the glue injection grooves 160 are used for injecting glue.

[0059] It is understandable that after injecting glue into the glue injection groove 160 , the microphone 200 can be further fixed on the positioning protrusion 150 by using the glue, thereby improving the reliability of fixing the microphone 200 .

[0060] When the user wears the earphone of the present invention and walks, or when the wind around the earphone is strong, the airflow can enter from one of the sound inlet channels 120 and then flow out from the other sound inlet channel 120, thereby reducing the airflow entering the sound inlet hole 110, and then reducing the pressure at the sound pickup hole of the microphone 200, achieving the purpose of reducing wind noise, and the noise reduction effect is good. In addition, the sealing pad 300 can play a sealing role, reduce the risk of sound leakage from the gap between the microphone 200 and the inner wall of the housing 100, and improve the call quality.

[0061] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example.

[0062] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
