DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0031] First, see Figure 1 and Figure 2 , is an open-type earphone 100 provided in an embodiment of the present application. The open-type earphone 100 may include a sound-emitting part 10, a battery compartment 20 and a connecting bridge 30. The sound-emitting part 10 is connected to a first end of the connecting bridge 30, and a second end of the connecting bridge 30 is connected to the battery compartment 20. The first end and the second end of the connecting bridge 30 are opposite ends. The sound-emitting part 10 may have a sound outlet 101. When the open-type earphone 100 is worn on the ear of a human body, the battery compartment 20 may be worn on the rear part of the earlobe of the human body, the sound-emitting part 10 may be worn in the concha cavity of the human body, the connecting bridge 30 may extend from the rear part of the earlobe of the human body to the front part of the earlobe, and extend to the concha cavity along the intertragus notch, so that the connecting bridge 30 can be worn on the earlobe of the human body, and the axis line of the sound outlet 101 forms an angle γ with the axis line of the ear canal, and γ satisfies: 45°≤γ≤50°.

[0032] Optionally, the sound-emitting part 10 is a component in the earphone that is responsible for converting electrical signals into sound signals. The sound-emitting part 10 can transmit sound to the human body. The sound-emitting part 10 is usually a speaker unit or a drive unit. The sound-emitting part 10 can be worn in the concha cavity of the human body, which helps to transmit the sound directly to the human ear canal, and can also reduce the interference of external noise and improve the sound quality experience. The sound-emitting part 10 can also be suspended at the intertragus notch of the human body, so that the intertragus notch can serve as a support point for the sound-emitting part 10. The sound-emitting part 10 can not only fit the human ear, but also can ensure that the sound-emitting part 10 will not fall off or shift during wearing through appropriate suspension methods.

[0033] When the sound-emitting part 10 is worn in the concha cavity of the human body, the sound-emitting part 10 does not completely close the human ear canal, the sound-emitting part 10 is located below the ear canal, and the sound outlet 101 can be arranged toward the human ear canal, and the axis of the sound outlet 101 and the axis of the ear canal form an angle of γ. When γ is less than 45°, the angle of γ is too small, which may cause the sound to be too close to the earlobe, increasing the reflection and loss of the sound on the skin. When γ is greater than 50°, the angle of γ is too large, which may cause the sound to deviate from the ear canal, resulting in reduced sound transmission efficiency.

[0034] Therefore, when γ satisfies: 45°≤γ≤50°, the appropriate angle γ helps to ensure that the sound enters the ear canal in the correct direction, improving the clarity and positioning of the sound. Even if the open earphone 100 shakes, the sound outlet 101 can always be arranged toward the ear canal during the shaking process, so that the sound-emitting part 10 can transmit the complete audio to the ear canal, which can reduce the feeling of unstable sound quality caused by shaking.

[0035] Optionally, a power source can be provided inside the battery compartment 20, and the battery compartment 20 can supply power to the sound-emitting part 10. The battery compartment 20 can be worn at the back of the human earlobe, so that the connecting bridge 30 can extend from the human concha cavity along the intertragus notch to the back of the earlobe, so that the connecting bridge 30 can be worn at the human earlobe, and the connecting bridge 30 can drive the battery compartment 20 and the sound-emitting part 10 to clamp the human ear, thereby increasing the wearing stability of the open earphone 100, and the connecting bridge 30 is located at the human earlobe in accordance with the direction of gravity, which can prevent the connecting bridge 30 from shaking up and down due to its own gravity. Even if the open earphone 100 is worn for a long time, the connecting bridge 30 will not cause pressure on the auricle, thereby increasing the wearing comfort of the open earphone 100.

[0036] See also Figure 2 In some embodiments, the second end of the connecting bridge 30 is connected to the side of the sound-emitting portion 10 facing away from the sound outlet 101 .

[0037] Optionally, the connecting bridge 30 can be located on the side of the sound-emitting part 10 facing away from the sound outlet 101, so that when the open earphone 100 is worn on the ear of a human body, the connecting bridge 30 can drive the sound outlet 101 of the sound-emitting part 10 to be arranged toward the ear canal of the human body, and the connecting bridge 30 can prevent the sound outlet 101 from shifting relative to the ear canal, which can improve the sound transmission efficiency. And connecting the second end of the connecting bridge 30 to the side of the sound-emitting part 10 facing away from the sound outlet 101 can also increase the distance between the connecting bridge 30 and the earlobe, which can prevent the connecting bridge 30 from pressing the earlobe, and increase the wearing comfort of the open earphone 100.

[0038] See also Figure 2 In some embodiments, the extension direction of the second end of the connecting bridge 30 can be set at an angle to the plane where the sound outlet 101 is located.

[0039] Optionally, when the open earphone 100 is worn on the human ear, the second end of the connecting bridge 30 can extend from the intertragic notch to the concha cavity, and when the extension direction of the second end of the connecting bridge 30 is set at an angle to the plane where the sound outlet 101 is located, the plane where the sound outlet 101 is located can be set toward the ear canal, so that the sound outlet 101 can transmit sound into the ear canal more effectively, reducing the scattering and loss of sound in the air.

[0040] See also Figure 3 and Figure 4 In some embodiments, the connecting bridge 30 can include a memory wire 301, one end of the memory wire 301 can be connected to the battery compartment 20, and the other end of the memory wire 301 can be connected to the sound-emitting part 10, and the memory wire 301 can drive the battery compartment 20 and the sound-emitting part 10 to clamp the human ear so that the sound outlet 101 is set toward the ear canal opening of the human body.

[0041] Optionally, the memory wire 301 can extend along the extension direction of the connecting bridge 30, and one end of the memory wire 301 is connected to the battery compartment 20, and the other end of the memory wire 301 is connected to the sound-emitting part 10. When the open-type earphone 100 is worn on the ear of a human body, the memory wire 301 can drive the battery compartment 20 and the sound-emitting part 10 to clamp the ear of the human body, thereby increasing the wearing stability of the open-type earphone 100. In addition, the memory wire 301 can also drive the sound outlet 101 to be arranged toward the ear canal of the human body, so that the sound outlet 101 can more effectively transmit the sound into the ear canal.

[0042] Optionally, the memory metal wire 301 can be embedded in the interior of the connecting bridge 30, which can protect the memory metal wire 301. The types of memory metal wire 301 can include memory titanium wire, nickel-titanium alloy wire, copper-based memory metal wire 301 (such as copper-zinc alloy, copper-aluminum alloy, etc.) and iron-based memory metal wire 301 (such as iron-manganese alloy, iron-platinum alloy, etc.), etc. The present application does not limit the type of memory metal wire 301.

[0043] Optionally, the connecting bridge 30 can be in a C-shape. When the open earphone 100 is worn on the human ear, one end of the connecting bridge 30 can be located at the back of the human earlobe and connected to the battery compartment 20, and the connecting bridge 30 can bend and extend from the back of the earlobe to the front of the earlobe, and extend along the intertragus notch to the concha cavity, and the other end of the connecting bridge 30 is connected to the sound-producing part 10.

[0044] See also Figure 4 In some embodiments, the memory metal wire 301 may include a first connecting segment 3011, a transition segment 3012 and a second connecting segment 3013 connected in sequence, the first connecting segment 3011 may be connected to the battery compartment 20, and the second connecting segment 3013 may be connected to the sound-emitting part 10, wherein an extension direction of the first connecting segment 3011 and an extension direction of the second connecting segment 3013 form an angle α, and α satisfies: 20°≤α≤40°.

[0045] Optionally, the memory metal wire 301 can include three parts, the first connecting segment 3011 and the second connecting segment 3013 are both straight segments, and the transition segment 3012 is an arc segment, so that the first connecting segment 3011, the transition segment 3012 and the second connecting segment 3013 connected in sequence can form a C-shaped structure, and because the memory metal wire 301 has the property of superelasticity, that is, it can undergo a large deformation without plastic deformation when subjected to external force, and can quickly return to its original shape when the external force is removed. Therefore, when the open earphone 100 is worn on the human ear, the memory metal wire 301 can drive the battery compartment 20 and the sound-emitting part 10 to clamp the human ear.

[0046] To be more clear, when the first connecting section 3011 is connected to the battery compartment 20 and the second connecting section 3013 is connected to the sound-emitting part 10, the transition section 3012 can drive the battery compartment 20 and the sound-emitting part 10 to maintain a relative positional relationship. In the process of wearing the open earphone 100 on the human ear, the sound-emitting part 10 fits against the human concha cavity, and the battery compartment 20 is worn on the back of the human earlobe. At this time, the sound-emitting part 10 and the battery compartment 20 move a certain distance away from each other under the action of external force. When the external force is removed, the transition section 3012 can drive the battery compartment 20 and the sound-emitting part 10 to return to their original relative positions, that is, the transition section 3012 can drive the battery compartment 20 and the sound-emitting part 10 to move towards each other, so that the battery compartment 20 and the sound-emitting part 10 can clamp the human ear, thereby stably wearing the open earphone 100 on the human ear.

[0047] Specifically, the angle α formed by the extension direction of the first connecting section 3011 and the extension direction of the second connecting section 3013 satisfies: 20°≤α≤40°. Within this angle range, a wearing space can be formed between the battery compartment 20 and the sound-emitting part 10, and the wearing space can be used to accommodate the human earlobe. When the human earlobe is located in the wearing space, the transition section 3012 can drive the battery compartment 20 and the sound-emitting part 10 to clamp the human ear, so that the battery compartment 20 and the sound-emitting part 10 can better fit and clamp the earlobe, thereby ensuring the wearing stability of the open earphone 100.

[0048] See also Figure 1 and Figure 4 In some embodiments, when the open earphone 100 is worn on the ear of a human body, the transition section 3012 can be bent and extend from the back of the earlobe to the front of the earlobe, and the angle between the extension direction of the second connecting section 3013 and the horizontal direction is β, and β satisfies: 65°≤β≤70°.

[0049] Optionally, when the open earphone 100 is worn on the ear of a human body, the first end of the transition section 3012 can be located behind the earlobe and connected to the first connecting section 3011, the second end of the transition section 3012 can be located in front of the earlobe and connected to the second connecting section 3013, and the angle β between the extension direction of the second connecting section 3013 and the horizontal direction satisfies: 65°≤β≤70°, so that when the open earphone 100 is worn on the ear of a human body, the second connecting section 3013 can be worn on the ear along the direction of the intertragus notch of the human body, and under the mutual cooperation of the second connecting section 3013 and the transition section 3012, the sound-emitting part 10 can be driven to clamp the ear more stably.

[0050] See also Figure 3 and Figure 4 In some embodiments, the connecting bridge 30 may include an outer shell 302, the two ends of the outer shell 302 are respectively connected to the battery compartment 20 and the sound-emitting part 10, a wire cavity 3020 may be formed inside the outer shell 302, a memory metal wire 301 may be provided inside the wire cavity 3020, and the outer shell 302 is made of soft material.

[0051] Optionally, the two ends of the outer shell 302 are respectively connected to the battery compartment 20 and the sound-emitting part 10, which can increase the structural strength of the open earphone 100. The wire cavity 3020 can be extended along the extension direction of the outer shell 302, and the wire cavity 3020 can pass through the opposite ends of the outer shell 302, so that when the memory wire 301 is set in the wire cavity 3020, one end of the memory wire 301 can extend to connect with the battery compartment 20, and the other end of the memory wire 301 can extend to connect with the sound-emitting part 10. The hardness of the soft rubber of the outer shell 302 is 80A-90A, so that the outer shell 302 can protect the memory wire 301, and the outer shell 302 can also increase the comfort of the open earphone 100 when worn. The material of the outer shell 302 is a soft material, which can also facilitate the memory wire 301 to drive the battery compartment 20 and the sound-emitting part 10 to restore their original relative positions, or it can be said that it is convenient for the memory wire 301 to drive the battery compartment 20 and the sound-emitting part 10 to clamp the ear.

[0052] See also Figure 3 and Figure 4In some embodiments, the outer shell 302 may include a first shell 3021, an arc-shaped shell 3022 and a second shell 3023 which are connected in sequence. The first shell 3021 extends into the interior of the battery compartment 20 and is connected to the battery compartment 20. The second shell 3023 is connected to the sound-emitting part 10. When the open earphone 100 is worn on the ear of a human body, the arc-shaped shell 3022 bends and extends from the back of the earlobe to the front of the earlobe, and the angle between the extension direction of the second shell 3023 and the horizontal direction is β, and β satisfies: 65°≤β≤70°, so that the outer shell 302 can fit the ear better.

[0053] See also Figure 4 In some embodiments, the connecting bridge 30 further includes a sleeve portion 303, the sleeve portion 303 is located in the wire cavity 3020, and the sleeve portion 303 is sleeved on the end of the memory metal wire 301, and the material of the sleeve portion 303 is a hard material.

[0054] Optionally, the outer contour of the sleeve portion 303 is a cylindrical structure, and a sleeve portion 303 can be provided at the first end of the memory wire 301, and a sleeve portion 303 can also be provided at the second end of the memory wire 301. The first end and the second end of the memory wire 301 are opposite ends. The first end of the memory wire 301 can be connected to the battery compartment 20, and one sleeve portion 303 is located at the connection between the memory wire 301 and the battery compartment 20. The second end of the memory wire 301 can be connected to the sound-emitting portion 10, and the other sleeve portion 303 is located at the connection between the memory wire 301 and the sound-emitting portion 10. The material of the sleeve portion 303 is a hard material, so that the sleeve portion 303 can increase the rigidity of the connection between the memory wire 301 and the battery compartment 20, and increase the rigidity of the connection between the memory wire 301 and the sound-emitting portion 10, so that the memory wire 301 can better drive the battery compartment 20 and the sound-emitting portion 10 to clamp the ear.

[0055] See also Figure 4 In some embodiments, one end of the memory metal wire 301 can be electrically connected to the power source in the battery compartment 20 , and the other end of the memory metal wire 301 can be electrically connected to the sound-emitting part 10 .

[0056] Optionally, the first connecting segment 3011 can extend into the battery compartment 20, and the first connecting segment 3011 can be electrically connected to the power supply in the battery compartment 20, and the second connecting segment 3013 can extend into the sound-emitting part 10, and the second connecting segment 3013 can be electrically connected to the sound-emitting part 10, so that the power supply in the battery compartment 20 can supply power to the sound-emitting part 10 through the memory wire 301.

[0057] See also Figure 1 and Figure 5In some embodiments, when the open earphone 100 is worn on the ear of a human body, there can be a gap between the connecting bridge 30 and the earlobe of the human body.

[0058] Optionally, when the open earphone 100 is worn on the human ear, there may be a gap between the outer shell 302 of the connecting bridge 30 and the earlobe. To be more specific, there is a gap between the first shell 3021 of the outer shell 302 and the back of the earlobe, there is a gap between the arc-shaped shell 3022 of the outer shell 302 and the bottom of the earlobe, and there is a gap between the second shell 3023 of the outer shell 302 and the front of the earlobe. This can prevent the connecting bridge 30 from hitting the auricle, thereby preventing the connecting bridge 30 from clamping the auricle cartilage and causing pain to the human body, thereby improving the comfort of wearing the open earphone 100.

[0059] See also Figure 1 and Figure 5 In some embodiments, the distance between the connecting bridge 30 and the earlobe is d, and d satisfies: 1mm≤d≤5mm.

[0060] Optionally, when the open-type earphone 100 is worn on the ear of a human body, the distance d between the connecting bridge 30 and the earlobe satisfies: 1mm≤d≤5mm. When d is too small, that is, d is less than 1mm, the connecting bridge 30 may be close to the earlobe, and wearing the open-type earphone 100 for a long time may cause the earlobe to feel oppressive or uncomfortable. When d is too large, that is, d is greater than 5mm, although the feeling of oppression of the open-type earphone 100 on the earlobe is avoided, the open-type earphone 100 may shake easily when worn due to the large distance, affecting stability. Therefore, when 1mm≤d≤5mm, the open-type earphone 100 can be worn stably and the feeling of oppression of the open-type earphone 100 on the earlobe can be prevented.

[0061] See also Figures 3 to 5 In some embodiments, the outer wall of the battery compartment 20 may have a curved surface 201, and when the open earphone 100 is worn on the ear of a human body, the curved surface 201 may fit with the back of the earlobe of the human body.

[0062] Optionally, the outer wall surface of the battery compartment 20 can be a curved surface 201, and the curved surface 201 can be adapted to the curved surface of the back of the earlobe, so that the battery compartment 20 fits more closely to the back of the earlobe, and the back of the earlobe can provide wearing support to maintain the stability of the open earphone 100 when worn. It can also prevent the battery compartment 20 from causing pressure on the back of the earlobe, thereby improving the wearing comfort of the open earphone 100.

[0063] In a second aspect, an embodiment of the present application provides an earphone assembly, which may include an open-type earphone 100 and a charging box, wherein the charging box is used to accommodate the open-type earphone 100 so as to be able to charge the open-type earphone 100.

[0064] Optionally, the number of open-type earphones 100 is, for example, two, and two connected or unconnected charging spaces can be formed in the charging box, respectively used to accommodate two open-type earphones 100. The beneficial effects of the earphone assembly in the present application are the same as those of the open-type earphones 100 in the present application, and will not be repeated here.
