[0002] When wearing bone conduction headphones, the headphone head is located in front of the ear and the ear hole of the external auditory canal is exposed to the outside. When exercising with the headphones, the airflow moves from the headphone head to the side where the ear is, which inevitably generates wind noise.

[0059] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some structures related to the present application are shown in the accompanying drawings, rather than all structures. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0060] The terms "including" and "having" and any variations thereof in this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products or devices.

[0061] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0062] like Figures 1 to 3 As shown, a bone conduction earphone head corresponding to a preferred embodiment of the utility model includes a shell 1 and a windshield 2.

[0063] The housing 1 includes a contact surface 10 for fitting with the skin of a person's face. When the bone conduction earphone head is worn on the head of a person, the contact surface 10 contacts the skin of the face to transmit vibration. In some embodiments, the housing 1 includes a base shell 12 with an opening at one end and a face cover 13 connected to the base shell 12, and the face cover 13 is provided with the contact surface 10.

[0064] The windshield 2 is connected to the housing 1 and protrudes from the housing 1. When the bone conduction earphone head is worn on the human head, the windshield 2 extends toward the side where the human ear is located. The windshield 2 and the housing 1 can be integrally formed, or can be fixedly connected to the housing 1 by gluing or welding.

[0065] When a user wears bone conduction headphones and moves at a certain speed, the airflow will form turbulence in the rear area of ​​the headphone head, thereby generating wind noise. By providing a wind shield 2 on the housing 1, the wind noise airflow can be directed away from the external auditory canal. Compared with the existing technology (such as using algorithm noise reduction), providing a wind shield 2 can reduce the wind noise in the ear at the root.

[0066] like Figures 3 to 5 As shown, the length direction of the windshield 2 is the coordinate axis X direction, the width direction is the coordinate axis Y direction, and the thickness direction is the coordinate axis Z direction. Preferably, the width direction of the windshield 2 is consistent with the length direction of the bone conduction earphone head, the length direction is consistent with the width direction of the bone conduction earphone head, and the thickness direction is consistent with the thickness direction of the bone conduction earphone head. The protruding length A of the windshield 2 is set to 1mm to 20mm, and the average width B is 5mm to 30mm. Optionally, the maximum width of the windshield 2 does not exceed 35mm.

[0067] Herein, the protruding length A of the wind shield 2 refers to the shortest distance between its outer end and the connection between the wind shield 2 and the outer shell 1, the average width of the wind shield 2 refers to the average value of its maximum width B1 and minimum width B2, and the average thickness of the wind shield 2 refers to the average value of its maximum thickness D1 and minimum thickness D2.

[0068] like Figure 6 As shown, Figure 6 In the embodiment shown, the protruding length A of the windshield 2 of the bone conduction earphone head is 1 mm, and the average width B is 5 mm. Figure 7 for Figure 6 The sound pressure level cloud diagram of the bone conduction earphone head of the shown embodiment is close to the face in a wind speed of 10m / s. The figure simulates the sound pressure changes at the back (the side where the ear is located) of the bone conduction earphone head in a wind speed of 10m / s. Figure 8 for Figure 7 The sound pressure level cloud chart behind the bone conduction earphone head is hidden to conveniently show the sound pressure level in the area behind the bone conduction earphone head. The center of the circle in the figure is about 10mm away from the edge of the earphone housing 1, that is, the circle shows the approximate position of the human external auditory canal. In the figure, the maximum sound pressure level at the corresponding position of the human external auditory canal is about 24.9dB. Fig.30 and Fig.31 As shown, Fig.30The sound pressure level cloud diagram of the bone conduction earphone headphone without wind shield 2 close to the face in a wind speed of 10m / s is shown. The figure simulates the sound pressure change at the back (the side where the ear is located) of the bone conduction earphone headphone head in a wind speed of 10m / s. Fig.31 for Fig.30 The sound pressure level cloud chart behind the bone conduction earphone head is used to conveniently indicate the sound pressure level in the rear area of ​​the bone conduction earphone head. The center of the circle in the figure is about 10 mm away from the edge of the earphone housing 1, that is, the circle shows the approximate position of the human external auditory canal. In the figure, the maximum sound pressure level at the corresponding position of the human external auditory canal is about 25.5 dB. Obviously, after the wind shield 2 is set, the wind noise heard by the human ear can be reduced.

[0069] like Fig. 9 As shown, Fig. 9 In the illustrated embodiment, the protruding length A of the windshield 2 of the bone conduction earphone head is 10 mm, and the average width B is 20 mm. Fig.10 for Fig. 9 The sound pressure level cloud diagram of the bone conduction earphone head of the embodiment shown in the figure is close to the face in a wind speed of 10m / s. Fig.11 for Fig.10 The sound pressure level cloud map after the bone conduction earphone head is hidden. The center of the circle in the figure is about 10mm away from the edge of the earphone housing 1, that is, the circle shows the approximate position of the human external auditory canal. In the figure, the maximum sound pressure level at the corresponding position of the human external auditory canal is about 8.7dB.

[0070] like Fig.12 As shown, Fig.12 In the embodiment shown, the protruding length A of the windshield 2 of the bone conduction earphone head is 20 mm, and the average width B is 30 mm. Fig.13 for Fig.12 The sound pressure level cloud diagram of the bone conduction earphone head of the embodiment shown in the figure is close to the face in a wind speed of 10m / s. Fig.14 for Fig.13 The sound pressure level cloud diagram after the bone conduction earphone head is hidden. The center of the circle in the figure is about 10mm away from the edge of the earphone housing 1, that is, the circle shows the approximate position of the human external auditory canal. In the figure, the maximum sound pressure level at the corresponding position of the human external auditory canal is about 2.7dB.

[0071] Figure 6 , Fig. 9 and Fig.12 In the bone conduction earphones of the embodiment shown, the distance between the windshield 2 and the contact surface 10 is the same, and the structural dimensions of the bone conduction earphones are also the same, and only the length and width of the windshield 2 are different. Figures 6 to 14It can be seen that in the process of increasing the protruding length A and the average width B of the wind shield 2, the sound pressure level in the area near the external auditory canal at the rear of the bone conduction earphone head will gradually decrease, and the area of ​​the wind shield is inversely proportional to the sound pressure level in the external auditory canal area.

[0072] As a preferred embodiment, the protruding length A of the windshield 2 is greater than or equal to 10 mm, and the average width B is greater than or equal to 20 mm, in which case the windshield 2 has a good noise reduction effect. Further preferably, the windshield 2 covers the outside of the external auditory canal.

[0073] In some embodiments, Figure 2 and Figure 3 As shown, the windshield 2 has a root portion 20 connected to the housing 1 and a sheet portion 21 connected to the root portion 20, and the thickness of the root portion 20 gradually decreases toward the outside of the housing 1, that is, the thickness of the root portion 20 connected to the housing 1 is greater, and the connection with the housing 1 is more secure. Optionally, the minimum thickness of the windshield 2 is not less than 0.5 mm, so that it has better strength.

[0074] like Figure 1 , Figure 4 and Fig.15 As shown, the housing 1 includes a connection portion 15 for connecting to the ear hook 4. In some embodiments, the windshield 2 is partially extended to be arranged opposite to the connection portion 15, so that the windshield 2 has a larger width and area, achieving a better noise reduction effect. As a feasible implementation, Fig.18 and Fig.19 As shown, the windshield 2 is connected to the connecting portion 15 or the ear hook 4, which can make the connection between the windshield 2 and the housing 1 more secure. Further preferably, there is no gap between the windshield 2 and the ear hook 4 to further reduce wind noise.

[0075] like Fig.15 and Fig.16 As shown, in one embodiment, the windshield 2 is of uniform thickness, with a thickness D of 0.6 to 5 mm. Figures 1 to 3 As shown, in another embodiment, the thickness D of the wind shield 2 gradually decreases toward the outside of the housing 1, and the minimum thickness D of the wind shield 2 is not less than 0.5 mm, so as to maintain the structural strength of the wind shield 2.

[0076] In some embodiments, the windshield 2 has different widths, for example, its surface is wavy or curved. Fig. 20 As shown, Fig. 20 In the embodiment, the surface 2a of the windshield 2 facing the contact surface 10 is planar, and the surface 2b facing the back surface 110 is curved, and its width gradually increases from both ends to the middle, so that the windshield 2 has good bending strength.

[0077] like Fig.15 and Fig.18 As shown, in one embodiment, the windshield 2 is of equal width. In other embodiments, the width of at least part of the windshield 2 gradually decreases toward the outside of the housing 1; for example, Figures 1 to 3 In the embodiment shown, the overall width of the windshield 2 gradually decreases toward the outer side of the housing 1; Figure 4 and Figure 5 In the illustrated embodiment, the width of the root portion 20 of the wind shield 2 gradually decreases toward the outer side of the housing 1, while the width of the sheet portion 21 is constant.

[0078] When the user wears the bone conduction earphone, the contact surface 10 contacts the human body. In order to ensure that the windshield 2 does not contact the human body and affect the wearing comfort, the windshield 2 and the contact surface 10 are arranged to be spaced apart along the thickness direction of the bone conduction earphone head (i.e., the Z direction of the coordinate axis); the housing 1 has a back side 110 away from the facial skin, and the windshield 2 is close to the back side 110. Figure 5 and Fig.17 As shown, in one embodiment, the windshield 2 is connected to the back surface 110 and the transition is smooth; Fig.16 As shown, in another embodiment, the wind shield 2 and the back surface 110 are spaced apart along the thickness direction of the bone conduction earphone head.

[0079] like Fig. 20 As shown, Fig. 20 In the illustrated embodiment, the distance E between the windshield 2 and the contact surface 10 along the thickness direction of the bone conduction earphone head is 9 mm. Fig.21 This is the sound pressure level cloud chart of the bone conduction earphone head when it is close to the face in a wind speed of 10m / s. Fig. 22 for Fig.21 The sound pressure level cloud map after the bone conduction earphone head is hidden. The center of the circle in the figure is about 10mm away from the edge of the earphone housing 1, that is, the circle shows the approximate position of the human external auditory canal. In the figure, the maximum sound pressure level at the corresponding position of the human external auditory canal is about 10.7dB.

[0080] like Fig.23 As shown, Fig.23 In the illustrated embodiment, the distance E between the windshield 2 and the contact surface 10 along the thickness direction of the bone conduction earphone head is 3 mm. In the present application, the distance E between the windshield 2 and the contact surface 10 refers to the distance between the windshield 21 and the contact surface 10 in the thickness direction. Fig.24 This is the sound pressure level cloud chart of the bone conduction earphone head when it is close to the face in a wind speed of 10m / s. Fig.25 for Fig.24 The sound pressure level cloud map after the bone conduction earphone head is hidden. The center of the circle in the figure is about 10mm away from the edge of the earphone housing 1, that is, the circle shows the approximate position of the human external auditory canal. In the figure, the maximum sound pressure level at the corresponding position of the human external auditory canal is about 8.7dB.

[0081] Fig. 20 and Fig.25 In the illustrated embodiment, the protruding length A, width and thickness of the windshield 2 remain unchanged, and only the distance between the windshield 2 and the contact surface 10 changes. Figure 20 to Figure 25 It can be seen that the closer the wind shield 2 is to the contact surface 10, the better the effect of reducing wind noise. Taking into account the wearing comfort, the distance E is preferably greater than or equal to 3 mm. The range of the distance E can be, for example, 3 to 15 mm. Preferably, the distance E is in the range of 3 to 9 mm, which can take into account both wearing comfort and the effect of reducing wind noise.

[0082] like Fig.19 As shown, in one embodiment, the windshield 2 is in the shape of a straight sheet as a whole. In another embodiment, the windshield 2 includes an arc-shaped sheet portion 21; for example, Fig.26 In the embodiment shown, the sheet 21 is bent toward the side where the head is located. In this embodiment, the windshield sheet 2 is preferably able to extend to cover the ear hole to prevent the airflow from being directed to the ear canal. Fig. 27 In the illustrated embodiment, the sheet 21 is bent toward the side facing away from the head, so as to direct the airflow away from the ear canal.

[0083] like Figure 2 As shown, the bone conduction earphone head also includes a vibration device 3 and a bone conduction microphone 5 arranged in the shell 1. The bone conduction microphone 5 is directly connected to the shell 1 or connected through a hard part. Fig.28 In the embodiment shown, the bone conduction microphone 3 is arranged on the inner surface of the cover 13 facing the vibration device 3. Figure 2 In the illustrated embodiment, the bone conduction microphone 3 is disposed on the circuit board 14. The bone conduction microphone 5 recognizes the call signal by picking up the vibration of the skull, and is less affected by the external environmental noise, thereby avoiding the influence of the external environmental noise on the recognition of the call sound by the bone conduction microphone 5. In order to improve the working efficiency of the vibration device 3, the vibration device 3 is disposed at a position close to the contact surface 10 and abuts against the cover 13, thereby reducing the loss of the vibration generated by the vibration device 3 in the process of propagating to the human body.

[0084] like Figure 2 and Fig.28 As shown, the housing 1 comprises a base housing 12 with an opening at one end, a cover 13 connected to the open end of the base housing 12, and a circuit board 14 disposed between the cover 13 and the back plate 11 of the base housing 12, the cover 13 is provided with a contact surface 10, the back plate 11 is provided with a back surface 110, and the back surface 110 and the contact surface 10 are respectively located on both sides of the housing 1. The base housing 12 is an integrally formed single part, which comprises a first housing 120 facing away from the human body and an annular second housing 121, the back plate 11 is disposed on the first housing 120, and the second housing 121 is connected to the cover 13, for example, by gluing or snapping.

[0085] The wind shield 2 is connected to the outer shell 1. To ensure the comfort of the user when wearing the bone conduction headphones, and the impact of the wind shield 2 close to the human body on wearing and noise reduction, the wind shield 2 is preferentially arranged on the base shell 12 facing away from the human body, for example, it can be arranged on the first shell 120 and / or the second shell 121.

[0086] like Fig.29 As shown, the utility model also proposes a bone conduction earphone, which includes the bone conduction earphone head as described in any of the above items, a first compartment body 60, a second compartment body 61, and a back hook 7 connected between the first compartment body 60 and the second compartment body 61. In some embodiments, the first compartment body 60 is configured as a control compartment, and the second compartment body 61 is configured as a battery compartment. The ear hook 4 is designed in an arc shape and is used to hook on the human ear. The first compartment body 60 and the bone conduction earphone head as well as the second compartment body 61 and the bone conduction earphone head are connected by an ear hook 4, so that the bone conduction earphone head and the compartment body are fixed on both sides of the human ear. The back hook 7 and the ear hook 4 are both made of elastic material or include parts made of elastic material, and both are elastic, so that a clamping force is generated between the two bone conduction earphone heads and the human skin, thereby improving the stability of the earphone when worn.

[0087] The above are only specific implementations of the present invention, and any improvements made based on the concept of the present invention are considered to be within the protection scope of the present invention.
