Description

Technical Field

[0001] This application relates to the field of headphone technology, and more particularly to a type of headphone. Background Technology

[0002] Headphones are portable electronic devices that convert electrical signals into audible sound by being worn on the head or ears.

[0003] The related technology provides an in-ear headphone, which achieves physical fixation and acoustic sealing by inserting an earplug into the ear canal.

[0004] However, in some situations, earplugs can compress the ear canal, causing damage to it. Utility Model Content

[0005] This application provides an earphone that does not compress the ear canal.

[0006] This application provides an embodiment of an earphone, including:

[0007] Ear hooks have cavities extending along their extension direction so that they can deform under external force.

[0008] The earphone body, with one end of the earphone body connected to the ear hook;

[0009] The power supply component is connected to the other end of the ear hook and is electrically connected to the headphone body.

[0010] In one possible implementation, the end of the earphone body away from the ear hook and the end of the power supply component away from the ear hook together form an extension line. The extension line has a first angle with the width direction of the earphone body. The first angle varies from 0° to 30° under the action of external force.

[0011] In one possible implementation, the ear hook includes:

[0012] The opposing part is located on the side of the cavity that is opposite to the ear. The opposing part has a first length extending along the extension direction of the ear hook. The first length is 60mm to 70mm. The range of variation of the first length under external force is 0mm to 10mm.

[0013] The fitting part is located on the side of the cavity facing the ear. The fitting part has a second length extending along the extension direction of the ear hook. The second length is 35mm to 45mm. The range of variation of the second length under external force is 0mm to 20mm.

[0014] In one possible implementation, the ratio of the cavity volume to the ear hook volume is 10% to 80%.

[0015] In one possible implementation, the cavity has a third length extending along the extension direction of the ear hook, the third length being 20mm to 60mm.

[0016] In one possible implementation, the ratio of the radial width of the cavity to the radial width of the ear hook is 10% to 80%.

[0017] In one possible implementation, the extension direction of the end of the earphone body away from the ear hook has a second angle with the width direction of the earphone body, the second angle being 40° to 60°.

[0018] In one possible implementation, the extension direction of the earphone body toward the ear hook has a third angle with the width direction of the earphone body, the third angle being 45° to 75°.

[0019] In one possible implementation, the headphones also include a plurality of support members disposed within the cavity, the support members contacting the cavity wall.

[0020] In one possible implementation, the support is block-shaped, column-shaped, spherical, or ring-shaped.

[0021] In one possible implementation, the support members are spaced apart.

[0022] In one possible implementation, the support is a temperature-sensitive element, and the elastic modulus of the temperature-sensitive element decreases as the temperature increases.

[0023] In one possible implementation, the support is a silicone part, a plastic part, or a rubber part.

[0024] The earphones provided in this application embodiment, by setting an ear hook, allow the earphones to be hung on the ear. Compared with in-ear earphones in related technologies that embed earplugs into the ear canal, this avoids direct contact and pressure on the ear canal, thus effectively preventing ear canal damage. Secondly, by setting a cavity in the ear hook, which extends along the extension direction of the ear hook, the ear hook can deform under external force, thereby adapting to different ear sizes and improving the universality of the earphones. Furthermore, the cavity can reduce the stiffness of the ear hook, thereby reducing the elastic force exerted by the ear hook on the ear, thus reducing the pressure of the ear hook on the ear and improving wearing comfort. In addition, the cavity makes the ear hook lighter, which can reduce the pressure of the earphone's gravity on the ear. At the same time, by setting the earphone body and power supply component at both ends of the ear hook respectively, a "gravity fit" effect is formed. When the user wears the earphones, the weight of the earphone body and power supply component will act on both ends of the ear hook respectively, so that the earphones can fit more stably on the ear and are not easy to loosen or fall off.

[0044] Headphones are portable electronic devices that convert electrical signals into audible sound by being worn on the head or ears.

[0045] The related technology provides an in-ear headphone, which achieves physical fixation and acoustic sealing by inserting an earplug into the ear canal.

[0046] However, in some situations, such as when earplugs are inserted too deeply, they can compress the ear canal, causing damage to the ear canal.

[0047] To address the aforementioned technical problems, embodiments of this application provide an earphone. Figure 1 This is a schematic diagram of the structure of the earphone provided in an embodiment of this application; Figure 2 for Figure 1 The diagram shows the internal structure of the first type of ear loop 100; Figure 3 for Figure 1 The diagram shows the internal structure of the second type of ear hook 100.

[0048] Please see Figures 1 to 3 The headphones include: an ear hook 100, which has a cavity 110 extending along its extension direction so that the ear hook 100 can deform under external force; a headphone body 200, which is connected to one end of the ear hook 100; and a power supply unit 300, which is connected to the other end of the ear hook 100 and electrically connected to the headphone body 200.

[0049] The earphones provided in this application embodiment, by setting the ear hook 100, allow the earphones to be hung on the ear through the ear hook 100. Compared with the in-ear earphones in the related technology that embed the ear plug into the ear canal, this can avoid direct contact with and pressure on the ear canal, thereby effectively preventing ear canal damage.

[0050] Secondly, by providing a cavity 110 on the ear hook 100, which extends along the extension direction of the ear hook 100, the ear hook 100 can deform under external force, thereby allowing the ear hook 100 to adapt to ears of different sizes and improving the universality of the headphones.

[0051] Furthermore, the cavity 110 can reduce the stiffness of the ear hook 100, thereby reducing the elastic force exerted by the ear hook 100 on the ear, thus reducing the pressure of the ear hook 100 on the ear and improving wearing comfort.

[0052] In addition, the cavity 110 makes the ear hook 100 lighter, which can reduce the pressure of the headphones on the ears. At the same time, by placing the headphone body 200 and the power supply component 300 at both ends of the ear hook 100, a "gravity fit" effect is formed. When the user wears the headphones, the weight of the headphone body 200 and the power supply component 300 will act on both ends of the ear hook 100, so that the headphones can fit more stably on the ears and are not easy to loosen or fall off.

[0053] It should be noted that this embodiment does not limit the specific type of the power supply component 300. For example, the power supply component 300 is a battery compartment.

[0054] It should also be noted that the cavity 110 provided in this embodiment can be located inside the ear hook 100, or it can partially or completely penetrate the surface of the ear hook 100.

[0055] The preferred technical solution of the earphone according to the embodiments of this application is described below with reference to the accompanying drawings. Figure 4 for Figure 1 The diagram shows the internal structure of the third type of ear hook 100; Figure 5 for Figure 1 The diagram shows the internal structure of the fourth type of ear hook 100; Figure 6 for Figure 1 The diagram shows the internal structure of the fifth type of ear hook 100; Figure 7 for Figure 1 The diagram shows the sixth type of ear hook 100 structure.

[0056] In some embodiments, please refer to Figure 2 The end of the earphone body 200 facing away from the ear hook 100 and the end of the power supply unit 300 facing away from the ear hook 100 together form an extension line L. The extension line L and the width direction X of the earphone body 200 have a first angle I. The first angle I varies from 0° to 30° under the action of an external force. For example, the amount of change of the first angle I under the action of an external force is 0°, 15° or 30°.

[0057] The shape and size of human ears vary from person to person. By allowing the first angle I to vary from 0° to 30° under external force, headphones can better adapt to the ear characteristics of different users. When users with a smaller ear curvature wear headphones, little or no external force can be applied to make the headphones conform to the natural curve of the ear, reducing the feeling of foreign objects. In this case, the variation range of the first angle I under external force is small, approaching 0°. When users with a larger ear curvature wear headphones, greater external force can be applied to make the headphones conform to the natural curve of the ear, reducing the feeling of foreign objects. In this case, the variation range of the first angle I under external force is larger, approaching 30°.

[0058] In other embodiments, please refer to Figure 2 and Figure 3The ear hook 100 includes: a back part 130, which is located on the side of the cavity 110 away from the ear, and has a first length C extending along the extension direction of the ear hook 100, the first length C being 60mm to 70mm, and the first length C varying from 0mm to 10mm under external force; and a fitting part 120, which is located on the side of the cavity 110 facing the ear, and has a second length D extending along the extension direction of the ear hook 100, the second length D being 35mm to 45mm, and the second length D varying from 0mm to 20mm under external force.

[0059] The opposing portion 130 is located on the side of the cavity 110 opposite to the human ear, i.e., the outer portion of the ear hook 100. This opposing portion 130 has a first length C extending along the extension direction of the ear hook 100. By setting the first length C of the opposing portion 130 to 60mm to 70mm, it can be ensured that the ear hook 100 covers most of the outer contour of the user's auricle, providing sufficient support area. Exemplarily, the first length C is 60mm, 65mm, or 70mm.

[0060] By setting the variation range of the first length C of the diverging portion 130 under external force to 0mm to 10mm, when a user wears the headphones and applies external force to the ear hook 100, the diverging portion 130 can generate an elastic deformation of up to 10mm. On the one hand, allowing the diverging portion 130 to undergo a certain degree of deformation allows the ear hook 100 to better adapt to different users' ear shapes, enhancing the fit; on the other hand, limiting the deformation range to within 10mm ensures that the ear hook 100 maintains sufficient structural stability, preventing excessive deformation that could lead to insufficient support or structural damage. For example, the change in the first length C under external force is 0mm, 5mm, or 10mm.

[0061] The fitting portion 120 is located on the side of the cavity 110 facing the ear, i.e., the portion that directly contacts the ear. This fitting portion 120 has a second length D extending along the extension direction of the ear hook 100. By setting the second length D to 35mm to 45mm, it can be ensured that the fitting portion 120 can fully contact the inner contour of the user's auricle, providing a stable wearing experience. For example, the second length D is 35mm, 40mm, or 45mm.

[0062] By setting the variation range of the second length D of the fitting portion 120 under external force to 0mm to 20mm, the ear hook 100 can better fit auricles of different shapes and sizes, thereby improving wearing comfort and stability. For example, the variation of the second length D under external force is 0mm, 10mm, or 20mm.

[0063] In some other embodiments, the volume ratio of the cavity 110 to the ear hook 100 is 10% to 80%.

[0064] When the volume ratio of the cavity 110 to the ear hook 100 is less than 10%, the cavity 110 contributes limitedly to the overall elasticity of the ear hook 100, resulting in high stiffness and difficulty in adapting to different ear shapes. In this case, the ear hook 100 exerts significant pressure on the ear, easily leading to discomfort during prolonged wear. Conversely, when the volume ratio of the cavity 110 to the ear hook 100 exceeds 80%, the structural strength of the ear hook 100 is significantly reduced, making it prone to excessive deformation or structural damage under external forces, thus failing to provide stable wearing support.

[0065] Therefore, by setting the ratio of the volume of the cavity 110 to the volume of the ear hook 100 within the range of 10% to 80%, a better balance can be achieved between the elastic deformation capability and structural stability of the ear hook 100. Within this range, the ear hook 100 can maintain sufficient elasticity to adapt to different users' ear shapes, while also maintaining the necessary structural strength to provide stable wearing support.

[0066] In some embodiments, please refer to Figure 3 The cavity 110 has a third length E extending along the extension direction of the ear hook 100, and the third length E is 20mm to 60mm.

[0067] When the third length E of the cavity 110 is less than 20mm, the cavity 110 contributes little to the elasticity of the ear hook 100. The ear hook 100 has high overall rigidity, making it difficult to adapt to different ear shapes and exerting significant pressure on the ear, which can lead to discomfort after prolonged wear. When the third length E of the cavity 110 is greater than 60mm, although the elasticity of the ear hook 100 is significantly improved, the structural strength decreases accordingly. This makes it more susceptible to excessive deformation or structural damage under external forces, affecting the lifespan and stability of the headphones.

[0068] Therefore, by setting the third length E to 20mm to 60mm, a better balance can be achieved between the elastic deformation capability and structural stability of the ear hook 100. Within this range, the ear hook 100 can maintain sufficient elasticity to adapt to different users' ear shapes while maintaining the necessary structural strength to provide stable wearing support. For example, the third length E is 20mm, 40mm, or 60mm.

[0069] In other embodiments, please continue to refer to Figure 3 The ratio of the radial width F of the cavity 110 to the radial width G of the ear hook 100 is 10% to 80%.

[0070] When the ratio of the radial width F of the cavity 110 to the radial width G of the ear hook 100 is less than 10%, the cavity 110 has little impact on the overall stiffness of the ear hook 100 and cannot effectively reduce the pressure of the ear hook 100 on the ear. However, when this ratio is greater than 80%, the wall thickness of the ear hook 100 is too small, the structural strength is low, and it is prone to breakage or permanent deformation under external force, affecting the service life of the headphones.

[0071] By setting the ratio of the radial width F of the cavity 110 to the radial width G of the ear hook 100 to 10% to 80%, the ear hook 100 has sufficient elastic deformation capacity in the radial direction to adapt to different users' ear shapes, while maintaining the necessary structural strength to provide stable wearing support.

[0072] In some embodiments, please continue reading Figure 3 The extension direction of the end of the earphone body 200 away from the ear hook 100 has a second included angle A with the width direction X of the earphone body 200, and the second included angle A is 40° to 60°.

[0073] The position of the preauricular notch varies among different users. If the second included angle A is set too small, the position of the earphone body 200 will change when the ear hook 100 deforms under external force. This will cause the end of the earphone body 200 away from the ear hook 100 to not correspond to the position of the preauricular notch of the human ear. If the second included angle A is set too large, the manufacturing cost and weight of the earphone body 200 will be high. Therefore, this embodiment sets the second included angle A to 40° to 60°, which can balance the need for the earphone body 200 to correspond to the preauricular notch of the human ear and the need for low manufacturing cost and low weight of the earphone body 200. For example, the second included angle A is 40°, 50° or 60°.

[0074] In other embodiments, please continue to refer to Figure 3 The extension direction of the earphone body 200 toward the ear hook 100 has a third angle B with the width direction X of the earphone body 200, and the third angle B is 45° to 75°.

[0075] The position of the intertragus notch on different users' ears varies. If the third included angle B is set too small, the position of the earphone body 200 will also change when the ear hook 100 deforms under external force. This will cause the end of the earphone body 200 facing the ear hook 100 to not correspond to the position of the intertragus notch on the human ear. If the third included angle B is set too large, the manufacturing cost and weight of the earphone body 200 will be high. Therefore, this embodiment sets the third included angle B to 45° to 75°, which can balance the need for the earphone body 200 to correspond to the intertragus notch on the human ear and the need for low manufacturing cost and low weight of the earphone body 200. For example, the second included angle A is 45°, 60° or 75°.

[0076] In some other embodiments, please refer to Figure 3 The power supply unit 300 has a fourth length H extending along the length direction Y of the earphone body 200. The length direction Y of the earphone body 200 is perpendicular to the width direction X of the earphone body 200. The fourth length H is 20 to 40 mm.

[0077] In some embodiments, please refer to Figures 4 to 6 The headphones also include a support member 400, which contacts the cavity wall of the cavity 110. In some examples, there are multiple support members 400.

[0078] During the wearing of the headphones, the ear hook 100 needs to simultaneously meet the following requirements: sufficient flexibility to adapt to different ear shapes, and appropriate support to maintain stable wearing of the headphones. If the cavity 110 is too large or the wall thickness is too thin, although it can reduce the stiffness of the ear hook 100 and reduce the pressure on the ears, it may result in insufficient structural strength of the ear hook 100, which will not be able to effectively support the weight of the headphone body 200 and the power supply component 300, thus affecting the wearing stability. If the cavity 110 is too small or the wall thickness is too large, although the structural strength is guaranteed, it will increase the stiffness of the ear hook 100, which will increase the pressure on the ears and reduce wearing comfort.

[0079] To address the aforementioned technical issues, this embodiment incorporates multiple support members 400 within the cavity 110. These support members 400 contact the cavity wall of the cavity 110, ensuring that the ear hook 100 maintains good elasticity while also possessing high structural stability. When the ear hook 100 is subjected to external force, the support members 400 provide a certain reaction force, preventing excessive deformation or structural damage. Furthermore, since the support members 400 only contact the cavity wall at specific locations, rather than completely filling the cavity 110, the elastic characteristics of the cavity 110 structure are preserved, allowing the ear hook 100 to deform within a certain range and adapt to different users' ear shapes.

[0080] In specific implementation, when the cavity 110 is located inside the ear hook 100, the support member 400 can abut against or be fixedly connected to the cavity wall of the cavity 110; when the cavity 110 partially or completely penetrates the surface of the ear hook 100, the support member 400 can be connected to the cavity wall of the cavity 110.

[0081] It should be noted that this embodiment does not limit the shape of the support member 400; different shapes provide different support effects, and the appropriate shape can be selected based on specific needs. For some examples, please refer to [link / reference needed]. Figure 4 The support member 400 is block-shaped. See other examples. Figure 5 The support member 400 is spherical. In some other examples (not shown in the figure), the support member 400 is cylindrical or annular.

[0082] In some examples, please refer to Figure 4 and Figure 5 There are multiple support members 400, which are spaced apart. In this example, multiple support members 400 can improve the structural stability of the ear hook 100, while the spaced arrangement of multiple support members 400 can reduce the manufacturing cost and weight of the ear hook 100, and can keep the ear hook 100 flexible.

[0083] In addition, when the cavity 110 partially or completely penetrates the surface of the ear hook 100, the multiple support members 400 are spaced apart to facilitate heat dissipation from the human body.

[0084] For some other examples, please refer to Figure 6 There are multiple support members 400. Two adjacent support members 400 are connected in contact and can move relative to each other under the action of external force.

[0085] In this embodiment, when an external force is applied to the ear hook 100, the various support members 400 interact with each other, and the position of each support member 400 along the extension direction of the ear hook 100 does not change, thus providing a more stable support force for the ear hook 100. Furthermore, by setting two adjacent support members 400 to be movable relative to each other under the action of external force, the support members 400 do not hinder the deformation of the ear hook 100.

[0086] In practice, the cavity 110 is located inside the ear hook 100, and each support member 400 abuts against the inner wall of the cavity 110.

[0087] Furthermore, the support 400 is a temperature-sensitive component, and the elastic modulus of the temperature-sensitive component decreases as the temperature increases.

[0088] By setting the support component 400 as a temperature-sensitive component whose elastic modulus decreases with increasing temperature, when the user is not using the headphones, the support component 400 is at a lower temperature and has a higher elastic modulus, providing stronger support and improving the structural strength of the ear hook 100, thereby preventing the ear hook 100 from being damaged by unexpected external forces. When the headphones are worn on the ear, the body heat is conducted to the support component 400, causing its temperature to rise and its elastic modulus to gradually decrease. The support component 400 becomes softer, and the pressure on the ear is reduced, thereby alleviating the pressure caused by prolonged wear.

[0089] It should be noted that this embodiment does not limit the specific type of the support member 400. For example, the support member 400 is a silicone part, a plastic part, or a rubber part.

[0090] In some embodiments, the headphones also include an electrical connection cable (not shown in the figure), which is embedded in the ear hook 100, and the headphone body 200 is electrically connected to the power supply unit 300 through the electrical connection cable.

[0091] In other embodiments, at least one of the headphone body 200 and the power supply unit 300 is detachably connected to the ear hook 100.

[0092] In this embodiment, by detachably connecting the headphone body 200 to the ear hook 100, the user can replace different headphone bodies 200 according to different usage scenarios, such as switching between a headphone body 200 with a low sound leakage cavity, a headphone body 200 with dual high and low frequency SPK, and a headphone body 200 with a semi-in-ear structure.

[0093] By detachably connecting the power supply unit 300 to the ear hook 100, when the power supply unit 300 runs out of power, the user can replace it with a fully charged power supply unit 300; when the power supply unit 300 malfunctions, the user can remove the power supply unit 300 for maintenance or replace it with a new power supply unit 300.

[0094] In specific implementation, at least one of the earphone body 200 and the power supply component 300 is magnetically connected to the ear hook 100, and can be electrically connected to the electrical connection wire inside the ear hook 100 via a spring pin. Magnetic connection and spring pin connection are existing structural design methods in the art, and will not be described in detail here.

[0095] In other embodiments, please refer to Figure 7 The ear hook 100 has multiple fitting protrusions 140 for fitting with the human ear. The multiple fitting protrusions 140 are arranged in an array. The multiple fitting protrusions 140 can improve the fitting stability between the ear hook 100 and the human body through van der Waals forces.

[0096] It should be understood that the embodiments of this application are not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this application is limited only by the appended claims.
