[0028] In order to make the purpose, technical solutions and advantages of the present application more clear, the present application will be further described in detail below in combination 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 not to limit the present application.
[0029] In the prior art, a conventional ear clip type earphone corresponds to being clamped in the middle of the ear, and the earphone is fixed by clamping the middle of the pinna.
[0030] However, the ear hook part of the earphone protrudes along the middle part of the ear, and the exposed part of the ear hook is relatively large, which is easy to cause the ear hook to shake up and down, thereby driving the earphone to move, and the protruding ear hook is also easy to cause the earphone to be scratched and fall off, so that the earphone is not stable to wear. If stability is to be maintained, the ear hook needs to maintain a relatively large clamping force, and long-term wearing will cause compression to the auricle, and the comfort degree decreases.
[0031] Based on this, the open earphone 100 and the earphone assembly are provided in the embodiments of the present application, please refer to Figures 1 to 5 .
[0032] Specifically, please refer to Figure 1 and Figure 2 , the open earphone 100 in the present application includes a sound generating part 1, a battery compartment 2 and a connecting bridge 3, wherein the sound generating part 1 is used to be worn in the concha cavity of the human body, the battery compartment 2 is used to be worn at the back of the human body's ear lobe, one end of the connecting bridge 3 is connected with the sound generating part 1, the other end of the connecting bridge 3 is connected with the battery compartment 2, the connecting bridge 3 is used to clamp the auricle of the human body by the sound generating part 1 and the battery compartment 2, when the sound generating part 1 is worn in the concha cavity of the human body and the battery compartment 2 is worn at the back of the human body's ear lobe, the connecting bridge 3 is curved and extended from the back of the ear lobe to the front of the ear lobe; wherein the side of the battery compartment 2 close to the sound generating part 1 has a fitting surface 21, the fitting surface 21 is used to fit with the back of the ear lobe, and the fitting surface 21 is an arc surface extending along the side of the sound generating part 1.
[0033] The sound generating part 1 is the core component in the open earphone 100, which usually includes a loudspeaker unit and corresponding acoustic elements. It can be understood that the loudspeaker unit converts audio signals into sound waves, and since the sound generating part 1 is worn in the concha cavity of the human body, the sound waves can be transmitted to the ear canal through the concha cavity, thereby providing a clear sound experience. Specifically, the sound generating part 1 is suspended at the intertragic notch of the human body, so that the intertragic notch can serve as a support point for the sound generating part 1. The sound generating part 1 not only fits the human ear, but also ensures that it will not fall off or shift during wearing by using an appropriate suspension method, thereby further improving the sound quality effect of the sound generating part 1.
[0034] Specifically, the battery compartment 2 is used to power the sound generating part 1, and usually contains a battery and necessary circuit elements. In the embodiments of the present application, the battery compartment 2 is worn close to the back of the human body's ear lobe. Since the back of the human body's ear lobe is connected with the head, the open earphone 100 has a relatively fixed support point when worn at this position, and is not easy to fall off due to movement or rotation of the head.
[0035] In addition, the open earphone 100 further comprises a connecting bridge 3 connecting the sound generating part 1 and the battery compartment 2 respectively, so that the sound generating part 1 and the battery compartment 2 can have a certain clamping force, thereby being able to be stably worn on the pinna of the human body. Moreover, since the connecting bridge 3 is bent and extends from the rear part of the tragus to the front part of the tragus, the connecting bridge 3 is located at the tragus of the human body and is arranged in compliance with the direction of gravity, thereby ensuring the wearing stability of the open earphone 100 and effectively reducing the risk of the connecting bridge 3 being scratched and falling off.
[0036] Correspondingly, the side of the battery compartment 2 close to the sound generating part 1 has a fitting surface 21 for fitting with the rear part of the tragus of the human body. The fitting surface 21 extends along the circumferential side of the sound generating part 1 and forms an arc surface. The arc surface can better fit the shape of the rear part of the tragus of the human body, so that the battery compartment 2 can closely fit the rear part of the tragus of the human body. The design of the fitting surface 21 of the battery compartment 2 takes into account the shape of the pinna of the human body, which helps the battery compartment 2 to adapt to different ear structures, thereby improving the overall wearing comfort and ensuring the universality of the open earphone 100.
[0037] In some embodiments, please refer to Figure 2 and Figure 3 The fitting surface 21 is a circular arc surface. It can be understood that the design of the circular arc surface can better fit the natural curve of the rear part of the tragus of the human body, so as to reduce the gap between the battery compartment 2 and the rear part of the tragus of the human body, and ensure that the open earphone 100 can be more closely fitted and worn with the ear, thereby improving the comfort and stability of wearing. In addition, the fitting surface 21 is a circular arc surface, which can evenly distribute the pressure on the rear part of the tragus of the human body while fitting the contour of the ear, thereby reducing the pain or discomfort caused by excessive local pressure.
[0038] In order to further improve the fitting accuracy with the rear part of the tragus of the human body, the projection of the fitting surface 21 on the plane perpendicular to the axis of the fitting surface 21 is a first contour line 211, and the diameter of the circle on which the first contour line 211 is located is D1, 80mm≤D1≤120mm. Please continue to refer to Figure 3 The diameter of the circle corresponding to the first contour line 211 is between 80mm and 120mm, which can cover the size range of the tragus of most people, so that the open earphone 100 can better adapt to the ears of different users, and no matter the size of the ear, a suitable fitting position can be found. Further, by limiting the diameter range of the circle on which the first contour line 211 is located, the curvature of the fitting surface 21 can be ensured to match the natural curvature of the tragus of the human body, so as to evenly distribute the pressure on the rear part of the tragus, reduce the case of excessive local stress, and thereby improve the fitting degree and comfort of the fitting surface 21 and the rear part of the tragus of the human body.
[0039] In addition, the precise curvature matching makes the open earphone 100 less likely to slide during user activities, thereby providing better fixing effect and improving the stability of wearing.
[0040] Further, please refer to Figure 4 In the embodiments of the present application, the connecting bridge 3 comprises a memory wire 31 extending along the extension direction of the connecting bridge 3, one end of the memory wire 31 being connected with the battery compartment 2, and the other end of the memory wire 31 being connected with the sound production part 1. When the sound production part 1 is worn in the concha cavity of the human body, and the battery compartment 2 is worn at the back of the human body's earlobe, the memory wire 31 is used to drive the sound production part 1 and the battery compartment 2 to clamp the auricle of the human body.
[0041] It can be understood that when the open earphone 100 is worn on the auricle of the human body, the memory wire 31 has a certain ability to maintain deformation, thereby driving the sound production part 1 and the battery compartment 2 to clamp the auricle of the human body, increasing the stability of wearing the open earphone 100, and the connecting bridge 3 is arranged in compliance with the direction of gravity at the human body's earlobe, which can prevent the connecting bridge 3 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 3 will not cause compression to the auricle, and the comfort of wearing can be increased.
[0042] In some embodiments of the present application, the memory wire 31 can be embedded in the inside of the connecting bridge 3 to play a protective effect on the memory wire 31. The types of the memory wire 31 can include memory titanium wire, nickel-titanium alloy wire, copper-based memory wire 31 (such as copper-zinc alloy, copper-aluminum alloy, etc.), and iron-based memory wire 31 (such as iron-manganese alloy, iron-platinum alloy, etc.), and the like. The type of the memory wire 31 is not limited in the present application.
[0043] Further, please refer to Figure 4 The diameter of the cross section of the memory wire 31 is D2, and 0.4mm≤D2≤0.6mm. It can be understood that the diameter D2 of the memory wire 31 is between 0.4mm and 0.6mm, thereby optimizing the range of elasticity and strength of the memory wire 31. The memory wire 31 within the above diameter range has sufficient elasticity, which can be used to adjust the angle of the connecting bridge 3 when wearing and taking off the open earphone 100, and can also adjust the clamping force between the sound production part 1 and the battery compartment 2 when wearing the open earphone 100, thereby providing a flexible and comfortable wearing experience. Correspondingly, the memory wire 31 within this diameter range also has sufficient strength, which can effectively maintain the clamping effect of the sound production part 1 and the battery compartment 2 on the auricle of the human body, to ensure the stability and anti-slip performance of the open earphone 100, thereby reducing the compression to the auricle of the human body while providing the necessary support performance, so that there is still a better comfort feeling under long-term wearing.
[0044] Further, please continue to refer to Figure 4 The connecting bridge 3 further comprises an outer shell 32, two ends of the outer shell 32 are connected to the sound generating part 1 and the battery compartment 2, an internal space of the outer shell 32 is formed as a wire cavity, the memory metal wire 31 is arranged in the wire cavity, and the material of the outer shell 32 is a soft material.
[0045] In order to enhance the comfort of wearing, the connecting bridge 3 further comprises an outer shell 32, the outer shell 32 connects the sound generating part 1 and the battery compartment 2, the wire cavity extends along the extension direction of the outer shell 32, and the wire cavity penetrates through both ends of the outer shell 32 along the extension direction, so that when the memory metal wire 31 is arranged in the wire cavity, one end of the memory metal wire 31 extends to be connected to the battery compartment 2, and the other end of the memory metal wire 31 extends to be connected to the sound generating part 1. The outer shell 32 of the soft material can be used to provide a softer touch, reduce friction and pressure on the human skin, and form a natural curve that fits the pinna, reduce the sense of foreign matter, and improve the naturalness of wearing.
[0046] In addition, the soft material has a certain shock absorption effect, can absorb external impact force, and protect the memory metal wire 31 and other electronic elements inside from being damaged.
[0047] In some embodiments, the material of the outer shell 32 comprises a thermoplastic polyurethane material, which can be understood as having good elasticity and flexibility, and can deform with the bending of the memory metal wire 31 to ensure the utilization of the elastic performance of the memory metal wire 31. In addition, the thermoplastic polyurethane material has good wear resistance, can reduce wear caused by long-term wearing and using, prolong the service life of the open earphone 100, has good resistance to ultraviolet rays and chemicals, is not easy to age and become brittle, maintains long-term flexibility and strength. In other embodiments, the material of the outer shell 32 can also comprise other materials, such as silicone, rubber, etc., which are not limited in the present application.
[0048] Further, the hardness of the outer shell 32 is S, 80A≤S≤90A. It should be noted that the hardness of the outer shell 32 is evaluated by using Shore A hardness, which is suitable for soft materials. In the embodiments of the present application, the hardness of the soft glue of the outer shell 32 is in the range of 80A-90A, within which the outer shell 32 can maintain a certain strength and flexibility, so that the outer shell 32 can protect the memory metal wire 31, and also increase the comfort of wearing the earphone. The material of the outer shell 32 being a soft material can also facilitate the memory metal wire 31 to restore the original relative positions of the sound generating part 1 and the battery compartment 2, and facilitate the memory metal wire 31 to drive the sound generating part 1 and the battery compartment 2 to clamp the pinna of the human body.
[0049] Please refer to Figure 2 and Figure 4When the sound generating part 1 is worn in the concha cavity of the human body and the battery compartment 2 is worn at the back of the human body's earlobe, the connecting bridge 3 has a gap with the human body's earlobe. It is worth noting that the gap between the connecting bridge 3 and the earlobe can reduce the direct pressure of the connecting bridge 3 on the human body's earlobe, reduce the discomfort of the top ear caused by long-term wearing, and make the use of long-term wearing more comfortable.
[0050] In addition, the gap between the connecting bridge 3 and the human body's earlobe can improve the versatility of the open earphone 100, so that it can adapt to different ear shapes of different users. Even if the shape and size of the earlobe are different, a suitable wearing position can be found, and the user does not need to frequently adjust the position of the earphone. The gap can provide sufficient freedom, so that the open earphone 100 can naturally fit the ear.
[0051] In some embodiments, please refer to Figure 5 The connecting bridge 3 includes a first connecting segment 3a, a transition segment 3b and a second connecting segment 3c connected in sequence, the first connecting segment 3a is connected with the battery compartment 2, and the second connecting segment 3c is connected with the sound generating part 1. Wherein, the extension direction of the first connecting segment 3a and the extension direction of the second connecting segment 3c form an included angle α, and α satisfies: 20°≤α≤40°.
[0052] Specifically, the connecting bridge 3 includes three parts, the first connecting segment 3a and the second connecting segment 3c are both straight segments, and the transition segment 3b is an arc segment, so that the first connecting segment 3a, the transition segment 3b and the second connecting segment 3c connected in sequence can form a structure similar to C letter, the connecting bridge 3 has a certain holding force, when the open earphone 100 is worn on the human ear, the connecting bridge 3 can drive the sound generating part 1 and the battery compartment 2 to clamp the human pinna.
[0053] Further, when the first connecting segment 3a is connected with the battery compartment 2 and the second connecting segment 3c is connected with the sound generating part 1, the transition segment 3b can drive the sound generating part 1 and the battery compartment 2 to maintain a relative position relationship. In the process of wearing the open earphone 100 on the human ear, the sound generating part 1 is attached to the concha cavity of the human body, and the battery compartment 220 is worn at the back of the human body's earlobe. At this time, the sound generating part 1 and the battery compartment 2 move a certain distance in the direction away from each other under the action of external force. When the external force is removed, the transition segment 3b can drive the sound generating part 1 and the battery compartment 2 to restore to the original relative position, that is, the transition segment 3b can drive the sound generating part 1 and the battery compartment 2 to move in the direction close to each other, so that the sound generating part 1 and the battery compartment 2 can clamp the human ear, thereby stably wearing the open earphone 100 on the human ear.
[0054] Specifically, please refer to Figure 5The angle a formed by the extension direction of the first connecting section 3a and the extension direction of the second connecting section 3c satisfies 20°≤a≤40°, in this angle range, a wearing space can be formed between the sound production part 1 and the battery compartment 2, the wearing space can be used to accommodate the earlobe of the human body, and when the earlobe of the human body is located in the wearing space, the transition section 3b can drive the sound production part 1 and the battery compartment 2 to clamp the ear of the human body, so that the sound production part 1 and the battery compartment 2 can better fit and clamp the earlobe, and the stability of the open earphone 100 is ensured.
