[0002] Open-back headphones are a type of headphone with an auxiliary hanging ear hook on the side. When worn on the human ear, open-back headphones are usually ergonomically designed to ensure the stability of the ear hook structure and make them more practical.
[0003] In related technologies, if the ergonomic design of open-back headphones is not reasonable, they may easily fall off when worn. Utility Model Content
[0004] This application provides an open-back headphone that allows the ear hook's curvature to fit the ear more closely, thereby improving the universality of open-back headphones.
[0005] This application provides an open-back headphone, including:
[0006] An earphone body, at least a portion of which is used for wearing in the concha cavity, the earphone body having a first side side disposed away from the concha cavity;
[0007] An ear hook, connected to the main body of the earphone, is worn between the user's ear and head. The inner contour of the ear hook's orthographic projection on a first plane includes a first arc line, a second arc line, and a third arc line arranged sequentially and connected to each other. The first plane is parallel to the first side surface. The first arc line is close to the connection point between the ear hook and the main body of the earphone. The radii of the first arc line, the second arc line, and the third arc line increase sequentially.
[0008] In some embodiments of this application, the radius of the first arc is 6mm to 8mm; the radius of the second arc is 18mm to 21mm; and the radius of the third arc is 31mm to 33mm.
[0009] In some embodiments of this application, the center point corresponding to the first arc is the first center O1. The first arc has a first endpoint A and a second endpoint B. The first endpoint A is close to the connection between the ear hook and the headphone body, and the first endpoint A is used to contact the anterior edge of the helix of the user's auricle. The second endpoint B is connected to the second arc. The angle between the line connecting the first endpoint A and the first center O1 and the line connecting the second endpoint B and the first center O1 is in the range of 81° to 83°.
[0010] In some embodiments of this application, when the open-back headphones are worn, the horizontal distance between the first center O1 and the first endpoint A is between 6mm and 8mm, and the straight-line distance between the first center O1 and the headphone body is between 4mm and 5mm.
[0011] In some embodiments of this application, the center point corresponding to the second arc is the second center O2, the second arc has a third endpoint C, the third endpoint C is connected to the third arc, and the angle between the line connecting the third endpoint C and the second center O2 and the line connecting the second endpoint B and the second center O2 is in the range of 75° to 79°.
[0012] In some embodiments of this application, when the open-back headphones are worn, the intersection of the vertical line passing through the second center O2 and the second arc is the first reference point E. The first reference point E is located between the second endpoint B and the third endpoint C, and the first reference point E is used to contact the upper ear root of the user's auricle. The angle between the line connecting the first reference point E and the second center O2 and the line connecting the third endpoint C and the second center O2 is in the range of 66° to 68°.
[0013] In some embodiments of this application, the second center O2 and the first reference point E are located on the same vertical line, and the straight-line distance between the first reference point E and the headphone body is between 14mm and 16mm; when the open-back headphones are worn, the horizontal distance between the second center O2 and the first endpoint A is between 9mm and 11mm.
[0014] In some embodiments of this application, the center point corresponding to the third arc is the third center O3. When the open-back headphones are worn, the intersection of the horizontal line passing through the third center O3 and the third arc is the second reference point F. The angle between the line connecting the second reference point F and the third center O3 and the line connecting the third endpoint C and the third center O3 is in the range of 22° to 25°.
[0015] In some embodiments of this application, when the open-back headphones are worn, the vertical distance between the second reference point F and the first reference point E is between 23.5 mm and 25.5 mm, and the horizontal distance between the second reference point F and the first endpoint A is between 30 mm and 32 mm.
[0016] In some embodiments of this application, the angle between the central axis of the ear loop and the first plane is in the range of 5° to 7°.
[0017] Based on the open-back headphones in this application embodiment, this embodiment designs the specific shape of the inner side of the ear hook, that is, sets the inner contour of the ear hook's orthographic projection on the first plane as multiple different arcs, in order to increase the contact area between the inner side of the ear hook and the auricle, thereby reducing the pressure of the inner side of the ear hook on the ear. At the same time, the segmented design of the inner side of the ear hook can make the curvature of the ear hook fit the auricle more closely, thereby improving the universality of open-back headphones.

[0033] To more clearly illustrate the technical solutions in the embodiments of this application or related technologies, a clear and complete description will be provided below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0034] In related technologies, some open-back headphones have unreasonable ergonomic designs, which can cause them to be too loose when worn on the ear, making them prone to falling out; or they may be too tight, causing discomfort by pressing on the ear. Both of these issues reduce the user's wearing experience.
[0035] For the above situation, please refer to Figures 1-2 This application proposes an open-back headphone 1, including a headphone body 10 and an ear hook 20, wherein at least a portion of the headphone body 10 is used for wearing in the concha cavity 201 (e.g., Figure 9 As shown, the ear hook 20 is connected to the headphone body 10 and is used to be worn between the user's ear 2 and head.
[0036] The headphone body 10 has a first side 11 and a second side 12 opposite to the first side 11. The first side 11 is disposed away from the concha cavity 201, and the second side 12 is provided with a sound outlet 13. The sound outlet 13 is disposed facing the user's concha cavity 201 and ear canal. The sound in the open-back headphone 1 enters the user's ear canal from the sound outlet 13 to provide the user with various sounds.
[0037] See Figures 3-4 The inner contour of the ear hook 20 projected onto the first plane includes a first arc line 21, a second arc line 22, and a third arc line 23 arranged sequentially and connected to each other. The first plane is parallel to the first side surface 11. The first arc line 21 is located near the connection between the ear hook 20 and the headphone body 10. For example, as shown... Figure 3 As shown, the first arc 21, the second arc 22, and the third arc 23 are different line styles. When the open-back headphones 1 are worn, the inner side of the ear hook 20 contacts the user's earlobe 2.
[0038] Specifically, the first arc 21, the second arc 22, and the third arc 23 are all partial arcs on a circle, that is, the first arc 21, the second arc 22, and the third arc 23 each correspond to a partial arc on a circle (e.g., Figures 6-8 As shown, the radii of the first arc 21, the second arc 22, and the third arc 23 increase sequentially, meaning that the radii of the circles corresponding to the first arc 21, the second arc 22, and the third arc 23 increase sequentially. It can be understood that the curvature of the first arc 21, the second arc 22, and the third arc 23 decreases sequentially, meaning that the lines of the first arc 21, the second arc 22, and the third arc 23 gradually become smoother.
[0039] It should be noted that when the open-back headphones 1 are worn, the inner side of the ear hook 20 will contact the user's auricle 2, and under the influence of gravity of the open-back headphones 1, the inner side of the ear hook 20 will also compress the auricle 2, generating a force between them. This embodiment of the application increases the contact area between the inner side of the ear hook 20 and the auricle 2 by designing the specific shape of the inner side of the ear hook 20, that is, by setting the inner contour of the ear hook 20's orthographic projection on the first plane as multiple different arcs. This reduces the pressure of the inner side of the ear hook 20 on the ear. Simultaneously, the segmented design of the inner side of the ear hook 20 allows the curvature of the ear hook 20 to better fit the auricle 2, thereby improving the universality of the open-back headphones 1.
[0040] It is understandable that the first arc 21 can be directly connected to the headphone body 10, or the first arc 21 can be connected to the headphone body 10 through another arc; the third arc 23 can extend directly to the end of the inner contour of the ear hook 20, or when the open-back headphone 1 is worn, the end of the ear hook 20 does not contact the user's auricle 2, then the third arc 23 can also be connected to the end of the inner contour of the ear hook 20 through another arc.
[0041] It should also be noted that the ear hook 20 is generally made of silicone material, and it is encapsulated with materials such as memory metal to enhance its elasticity and stability, better adapt to different ear shapes, and provide support when wearing open-back headphones 1, ensuring that the ear hook 20 can fit firmly against the contour of the ear and that the headphone body 10 can correspond to the ear canal, reducing the pressure of the open-back headphones 1 on the ears. The ear hook 20 may include a soft rubber shell and a metal wire, with the metal wire located inside the soft rubber shell. Essentially, the soft rubber shell covers the outer periphery of the metal wire, making the ear hook 20 elastic and softer when worn, thus improving user comfort. The metal wire is preferably memory titanium wire, which has good elasticity, allowing users to adjust the wearing angle and clamping tightness of the ear hook 20, thus enabling the open-back headphones 1 to be worn more securely through the ear hook 20.
[0042] Please see Figure 5 In some embodiments of this application, the angle between the central axis of the ear hook 20 and the first plane is in the range of 5° to 7°. For example, taking the angle between the central axis of the ear hook 20 and the first plane as α, preferably, the angle α between the central axis of the ear hook 20 and the first plane is 6°.
[0043] It is understandable that the wearing of the open-back headphones 1 is achieved by the ear hook 20 and the headphone body 10 working together to clamp the user's ear 2. In this embodiment, by limiting the angle α between the central axis of the ear hook 20 and the first plane, the space formed between the ear hook 20 and the headphone body 10 can clamp the user's ear 2 more stably, thereby reducing the risk of the open-back headphones 1 falling off the user's ear 2.
[0044] Regarding the first arc 21, in some embodiments of this application, such as Figure 6 As shown, the radius of the first arc 21 is 6mm to 8mm, which means that the first arc 21 is a part of a circle with a radius of 6mm to 8mm.
[0045] Please see Figure 6 The center point corresponding to the first arc 21 is the first center O1. The first arc 21 has a first endpoint A and a second endpoint B. The first endpoint A is close to the connection between the ear hook 20 and the headphone body 10, and the first endpoint A is used to connect with the front edge 202 of the helix of the user's auricle 2 (e.g., Figure 9 As shown, the second endpoint B is in contact with the second arc 22, that is, the second endpoint B is the intersection of the first arc 21 and the second arc 22.
[0046] There is an angle Ⅰ between the line connecting the first endpoint A and the first center O1 and the line connecting the second endpoint B and the first center O1. The value of angle Ⅰ ranges from 81° to 83°. It can be understood that the central angle (central angle ∠AO1B, i.e., angle Ⅰ) formed by the radii passing through the two ends of the first arc 21 is between 81° and 83°. At the same time, the arc length range of the first arc 21 can be determined based on the radius range corresponding to the first arc 21.
[0047] Specifically, when the open-back earphone 1 is worn, the horizontal distance between the first center O1 and the first endpoint A is H1, where H1 is between 6mm and 8mm. Preferably, the first center O1 and the first endpoint A are on the same horizontal line. The straight-line distance between the first center O1 and the earphone body 10 is H2, where H2 is between 4mm and 5mm. This ensures that there is sufficient wearing space between the ear hook 20 and the earphone body 10, so that it can be worn on the user's auricle 2 and make relatively close contact with the auricle 2, and so that the specific position of the first center O1 can be determined.
[0048] Regarding the second arc 22, in some embodiments of this application, such as Figure 7 As shown, the radius of the second arc 22 ranges from 18mm to 21mm, meaning that the second arc 22 is a part of a circle with a radius ranging from 18mm to 21mm.
[0049] Please see Figure 7 The center point corresponding to the second arc 22 is the second center O2. The second arc 22 has a third endpoint C, which is connected to the third arc 23. That is, the third endpoint C is the intersection of the second arc 22 and the third arc 23.
[0050] There is an angle II between the line connecting the third endpoint C and the second center O2 and the line connecting the second endpoint B and the second center O2. The value of angle II ranges from 75° to 79°. It can be understood that the central angle (central angle ∠BO2C, i.e., angle II) formed by the radii passing through the two ends of the second arc 22 is between 75° and 79°. At the same time, the arc length range of the second arc 22 can be determined based on the radius range corresponding to the second arc 22.
[0051] Specifically, when the open-back earphone 1 is worn, the intersection of the vertical line passing through the second center O2 and the second arc 22 is the first reference point E. The first reference point E is located between the second endpoint B and the third endpoint C, and the first reference point E is used to connect with the upper ear root 203 of the user's auricle 2 (e.g., Figure 9As shown, when the open-back earphone 1 is worn, the first reference point E is the highest point on the inner side of the ear hook 20. An angle Ⅲ is formed between the line connecting the first reference point E and the second center O2 and the line connecting the third endpoint C and the second center O2. The angle Ⅲ ranges from 66° to 68°. It can be understood that angle Ⅲ is a part of angle Ⅱ.
[0052] The second center O2 and the first reference point E are located on the same vertical line. The straight-line distance between the first reference point E and the headphone body 10 is H3, which is between 14mm and 16mm. This ensures sufficient wearing space between the ear hook 20 and the headphone body 10, allowing for a comfortable fit and close contact with the user's ear 2. When the open-back headphone 1 is in the wearing state, the horizontal distance between the second center O2 and the first endpoint A is between 9mm and 11mm, which facilitates determining the specific positions of the first reference point E and the second center O2.
[0053] Regarding the third arc 23, in some embodiments of this application, such as Figure 8 As shown, the radius of the third arc 23 is 31mm to 33mm, which means that the third arc 23 is a part of a circle with a radius of 31mm to 33mm.
[0054] Please see Figure 8 The center point corresponding to the third arc 23 is the third center O3. When the open-back earphone 1 is worn, the intersection of the horizontal line passing through the third center O3 and the third arc 23 is the second reference point F. The line connecting the second reference point F and the third center O3 to the line connecting the third endpoint C and the third center O3 has an included angle IV, and the included angle IV ranges from 22° to 25°.
[0055] The third arc 23 has a fourth endpoint D, and the second reference point F is located between the third endpoint C and the fourth endpoint D. The tangent of the third arc 23 at the second reference point F extends vertically, as shown below. Figures 8-9 As shown, the third arc 23 contacts the back of the auricle 2. With the second reference point F as the dividing line, the arc CF part on the third arc 23 contacts the upper part of the back of the auricle 2, and the arc FD part on the third arc 23 contacts the lower part of the back of the auricle 2.
[0056] Specifically, when the open-back earphone 1 is worn, the second reference point F will contact the back side of the user's auricle 2. The vertical distance between the second reference point F and the first reference point E is H5, where H5 is between 23.5mm and 25.5mm. The horizontal distance between the second reference point F and the first endpoint A is H6, where H6 is between 30mm and 32mm. This facilitates the determination of the specific position of the second reference point F.
