Description

Technical Field

[0001] This utility model relates to the field of sound-producing devices, specifically to a headband-style headphone. Background Technology

[0002] Headphones are a pair of transducers that receive electrical signals from a media player or receiver and convert them into audible sound waves using speakers placed close to the ears. Headphones can be classified into...

[0003] In-ear headphones, over-ear headphones, non-in-ear headphones, bone conduction headphones.

[0004] Existing headphones, due to their fixed headbands, exert continuous pressure on the same area of ​​the user's head (e.g., the top of the head) in the coronal plane during prolonged wear, causing discomfort and even headaches. For example, patent application number 202320037199X discloses a type of headphone that specifically includes: a curved rod, a right accessory part, a left accessory part, a shell, and bending parts. A connecting wire is fixedly connected inside the curved rod. The right accessory part is fixedly connected to one end of the curved rod and has a control panel fixedly connected inside. One end of the connecting wire is electrically connected to the control panel. The left accessory part is fixedly connected to the end of the curved rod away from the right accessory part and has a battery fixedly installed inside. One end of the connecting wire is electrically connected to the battery. There are two bending parts, fixedly connected to the bottom of the right and left accessory parts respectively. There are two shells, fixedly connected to the bottom of the corresponding bending parts. Each shell has a cover fixedly connected to one side and a bone conduction speaker fixedly installed inside.

[0005] The aforementioned patent describes a device where a curved rod is worn on the outside of the head, with the bent portion covering both ears. A control panel drives bone conduction speakers, transmitting sound to the inner ear and cochlear nerve via skull vibrations, thus reducing the impact on hearing. However, because the curved rod is fixedly connected to two separate accessory parts, its prolonged placement on the outside of the head creates continuous pressure on a single area, causing discomfort. Therefore, improvements are needed. Utility Model Content

[0006] In view of the problems existing in the prior art, the purpose of this utility model is to provide a headband-style headphone that can adjust the wearing position of the headband on the head to avoid continuous pressure on a single position of the user's head.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] A headband-style headphone includes two headphone bodies and a headband. The two headphone bodies are movably connected to both ends of the headband. Each headphone body includes a retaining part, a hook-shaped part, and a bone conduction sound-generating part. The retaining part is connected to the front end of the hook-shaped part, and the bone conduction sound-generating part is positioned at the vibration location of the retaining part. In the wearing state, the headband is worn on the user's head, and the hook-shaped part is worn on the user's ears. The headband generates a clamping force that holds the two headphone bodies on the user's head. The rear end of the hook-shaped part is located between the back of the user's ear and the head, and the front end of the hook-shaped part passes through the space formed between the back of the ear and the head and is located in the cheek area adjacent to the user's ear. The retaining part is located in the cheekbone area close to the user's ear. Under the action of the clamping force, the vibration location of the retaining part contacts the cheekbone area.

[0009] Furthermore, when worn, the inner side of the front end of the hook-shaped part extends along the ear root toward the user's cheek, thereby allowing the retaining part to be close to the tragus.

[0010] Furthermore, the inner side of the front end of the hook-shaped portion has a first radius of curvature, and the outer side of the front end of the hook-shaped portion has a second radius of curvature, wherein the first radius of curvature is smaller than the second radius of curvature.

[0011] Furthermore, the cross-sectional area of ​​the front end of the hook-shaped portion gradually increases from the middle of the hook-shaped portion toward the end closer to the retaining portion.

[0012] Furthermore, the length of the outer side of the front end of the hook-shaped portion is greater than the length of the inner side of the front end of the hook-shaped portion.

[0013] Furthermore, a first protruding structure in a closed loop shape is provided at the vibration position. The first protruding structure protrudes from the inner surface of the retaining part, and the inner wall of the first protruding structure encloses a receiving cavity. The bone conduction vibrator of the bone conduction sound generating part is disposed in the receiving cavity.

[0014] Furthermore, the accommodating chamber is a closed space, and the outer surface of the bone conduction oscillator is in contact with the vibration surface of the accommodating chamber.

[0015] Furthermore, the accommodating chamber has an opening, and the outer surface of the bone conduction vibrator is flush with the vibration surface at the opening of the accommodating chamber, or the outer surface of the bone conduction vibrator protrudes from the vibration surface at the opening of the accommodating chamber; in the wearing state, the outer surface of the bone conduction vibrator is in contact with the cheekbone region.

[0016] Furthermore, when viewed from a direction away from the head, the cross-sectional dimension of the first protrusion structure is equal to the cross-sectional dimension of the retaining portion.

[0017] Furthermore, when viewed from a direction away from the head, the cross-sectional dimension of the first protrusion is smaller than the cross-sectional dimension of the retaining portion.

[0018] Furthermore, the protrusion height of the first protrusion structure is greater than or equal to the height of the tragus.

[0019] Furthermore, the vibration surface of the first protrusion structure matches the outer surface of the user's cheekbone region.

[0020] Furthermore, the outer surface of the retaining part is provided with a through hole, the through hole is connected to the interior of the first protrusion structure, and a first cover plate is provided in the through hole.

[0021] Furthermore, the inner side of the rear end portion of the hook-shaped portion has a third radius of curvature, and the outer side of the rear end portion of the hook-shaped portion has a fourth radius of curvature. The third radius of curvature is greater than the fourth radius of curvature, thereby allowing the inner side of the rear end portion of the hook-shaped portion to fit snugly against the back of the ear.

[0022] Furthermore, the length of the inner side of the rear end portion of the hook-shaped portion is less than the length of the outer side of the rear end portion of the hook-shaped portion, thereby allowing the outer side of the rear end portion of the hook-shaped portion to be in a meandering and curved shape and to connect with the inner side of the rear end portion of the hook-shaped portion.

[0023] Furthermore, a second protruding structure is provided on the inner surface of the rear end portion of the hook-shaped portion. The second protruding structure protrudes from the inner surface of the rear end portion of the hook-shaped portion, and the inner wall of the second protruding structure and the inner wall of the rear end portion of the hook-shaped portion together form an installation cavity.

[0024] Furthermore, when worn, the inner surface of the second protrusion abuts against the temporal bone, and under the leverage of the headband, the vibrating surface of the first protrusion abuts against the cheekbone.

[0025] Furthermore, it also includes a battery, a PCB, and wires, the battery and the PCB being disposed in the mounting chamber, one end of the wires being connected to the PCB, and the other end of the wires being connected to the bone conduction vibrator.

[0026] Furthermore, the head beam is generally arc-shaped, and a rotating mounting part is provided on the hook-shaped part, with the end of the head beam rotatably connected to the rotating mounting part.

[0027] Furthermore, a first reference line passes through the connection between the rotating mounting part and the headband part and is parallel to the user's sagittal plane. The rotating mounting part is provided with a first abutment part on the side near the retaining part. When the headband part rotates a first angle from the position of the first reference line toward the first abutment part, the headband part abuts against the first abutment part.

[0028] Furthermore, the first angle is in the range of 0°-45°.

[0029] Furthermore, a second reference line passes through the connection between the rotating mounting part and the head beam part and is parallel to the user's sagittal plane. A second abutment part is provided on the side of the rotating mounting part away from the holding part. When the head beam part rotates a second angle from the position of the second reference line towards the second abutment part, the head beam part abuts against the second abutment part.

[0030] Furthermore, the second angle ranges from 0° to 90°.

[0031] Furthermore, the rotating mounting portion includes a first sidewall and a second sidewall spaced apart, and the head beam is rotatably connected to the first sidewall and the second sidewall respectively via hinges.

[0032] The beneficial effects of this utility model are as follows:

[0033] I. This utility model allows the headband to rotate relative to the headphone body by movably connecting the headband to the headphone body. This allows users to choose the position of the headband on their head, thus solving the problem of traditional headband headphones where the headband position cannot be changed, resulting in continuous pressure on a single point of the head and causing discomfort to the user.

[0034] Second, this utility model is equipped with a bone conduction sound-generating part, which vibrates the cheekbone synchronously. The vibration of the cheekbone transmits this mechanical vibration signal directly to the cochlea, bypassing the external auditory canal and tympanic membrane. The cochlea converts the mechanical vibration signal into an electrical signal, which is finally transmitted to the brain by the auditory nerve, reducing the impact on hearing.

[0054] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "top surface", "bottom surface", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0055] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature. In this description of the utility model, "a number" means two or more, unless otherwise explicitly specified.

[0056] The reference to "embodiment" in this application means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0057] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0058] In this utility model, the term "front side of the ear" mentioned below is a concept relative to "back side of the ear." The former refers to the side of the ear that is away from the head, while the latter refers to the side of the ear that faces the head. Both of them refer to the user's ear.

[0059] In this embodiment, the sagittal plane, as mentioned below, is a vertical plane that extends from front to back, dividing the human body into two symmetrical parts, left and right. The coronal plane (also known as the frontal plane) is also a vertical plane that extends from left to right, dividing the human body into two parts, front and back. The horizontal plane (also known as the transverse plane) is a transverse plane that is parallel to the ground and divides the human body into two parts, upper and lower.

[0060] In this embodiment, "cheek" and "cheek region" generally refer to the side of the human face, that is, the facial area enclosed by the area from the front of the ear to the cheekbone, and from the zygomatic arch to the mandibular edge, which is common knowledge to those skilled in the art.

[0061] In this embodiment, "closer to the user's head" specifically refers to viewing from the external environment toward the user's head (directly facing the sagittal plane), and similarly, "far from the user's head" specifically refers to viewing from the user's head toward the external environment (far from the sagittal plane).

[0062] The utility model will be further described below with reference to the accompanying drawings and specific embodiments. The following description is merely exemplary and does not limit the scope of protection of the utility model.

[0063] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the back of a user's ear. The back of the ear 100 (i.e., the posterior side of the ear) includes physiological features such as the posterior scaphoid eminence 101, the antihelix groove 102, the antitragus groove 103, the triangular fossa eminence 104, the concha eminence 105, the lower ear root 106, and the upper ear root 107. Furthermore, the posterior scaphoid eminence 101, the triangular fossa eminence 104, and the concha eminence 105 have a certain volume and a certain degree of protrusion in the direction towards the head.

[0064] Please refer to Figure 2 , Figure 2 This is a schematic diagram of the front side of a user's ear. The front of the user's ear 200 (i.e., the auricle) may include physiological parts such as the external auditory canal 201, the concha cavity 202, the cymba conchae 203, the triangular fossa 204, the helix 205, and the tragus 206.

[0065] Please refer to Figure 3 , Figure 3 This is a schematic diagram of a user's head, which includes physiological features such as the zygomatic bone 300 and the temporal bone 301.

[0066] It should be further explained that the two earphone bodies 1 include a left earphone and a right earphone with a symmetrical design, and only the left earphone will be described in detail in this utility model.

[0067] Please refer to Figures 4-13A headband-style headphone includes two headphone bodies 1 and a headband 2, with the two headphone bodies 1 movably connected to both ends of the headband 2. Each headphone body 1 includes a retaining part 11, a hook-shaped part 12, and a bone conduction sound-generating part 13. The retaining part 11 is connected to the front end of the hook-shaped part 12, and the bone conduction sound-generating part 13 is positioned at a vibration position 111 on the retaining part 11. In the wearing state, the headband 2 is worn on the user's head, and the hook-shaped part 12 is worn on the user's ears. The headband 2 generates a clamping force that holds the two headphone bodies 1 on the user's head. The rear end of the hook-shaped part 12 is positioned between the back of the user's ear and the head, while the front end of the hook-shaped part 12 passes through the space formed between the back of the ear and the head and is located in the cheek area adjacent to the user's ear. The retaining part 11 is located in the cheekbone 300 area close to the user's ear. Under the action of the clamping force, the vibration surface 1111 of the vibration position 111 of the retaining part 11 contacts the cheekbone 300 area.

[0068] In this embodiment, please refer to Figure 6 , Figure 6 This is a schematic diagram of the planar structure of the earphone body 1. The front end of the hook-shaped part 12 includes the outer side surface of the front end of the hook-shaped part 12 and the inner side surface of the front end of the hook-shaped part 12. Figure 6 The middle AB segment can be considered as the outer surface of the anterior end of the hook-shaped part 12. Figure 6 The middle CD segment can be considered as the inner surface of the front end of the hook-shaped portion 12. The inner surface of the front end of the hook-shaped portion 12 has a first radius of curvature, and the outer surface of the front end of the hook-shaped portion 12 has a second radius of curvature, with the first radius of curvature being smaller than the second radius of curvature. Simultaneously, the cross-sectional area of ​​the front end of the hook-shaped portion 12 gradually increases from the middle of the hook-shaped portion 12 towards the end closer to the retaining portion 11. Therefore, in the wearing state, the inner surface of the front end of the hook-shaped portion 12 extends along the upper ear root 107 towards the user's cheek and connects with the retaining portion 11, thereby allowing the retaining portion 11 to approach the tragus 206. At the same time, the length of the outer surface of the front end of the hook-shaped portion 12 is greater than the length of the inner surface of the front end of the hook-shaped portion 12, allowing the outer surface of the front end of the hook-shaped portion 12 to have an extension direction slightly away from the user's ear and connect with the retaining portion 11. Viewed from the direction closest to the user's head, the connection between the outer side of the front end of the hook-shaped part 12 and the retaining part 11 is located to the left of the connection between the inner side of the front end of the hook-shaped part 12 and the retaining part 11, so that the retaining part 11 can be located in the zygomatic bone 300 region.

[0069] Please refer to Figure 7 , Figure 7This is a cross-sectional view of the headphone body 1 at ZZ'. In this embodiment, a first protruding structure 112 in a closed loop shape is provided at the vibration position 111 of the retaining part 11. This means that the outer wall of the first protruding structure 112 is a continuous and smooth curved surface connected end to end to form a closed loop. The first protruding structure 112 protrudes from the inner surface of the retaining part 11, and the inner wall of the first protruding structure 112 encloses a receiving chamber 1121. The bone conduction vibrator 131 of the bone conduction sound generating part 13 is disposed in the receiving chamber 1121. Specifically, in this embodiment, the accommodating chamber 1121 is a closed space, and the outer surface of the bone conduction oscillator 131 is in contact with the vibration surface 1111 of the accommodating chamber 1121 (the vibration surface 1111 is the inner surface of the accommodating chamber 1121). The bone conduction oscillator 131 transmits mechanical vibration to the vibration surface 1111 of the accommodating chamber 1121, and the vibration surface 1111 of the accommodating chamber 1121 further applies this mechanical vibration to the zygomatic bone 300.

[0070] In another embodiment, the accommodating chamber 1121 has an opening, specifically formed on the vibration surface 1111, allowing the accommodating chamber 1121 to communicate with the external environment. Specifically, the outer surface of the bone conduction vibrator 131 is flush with the vibration surface 1111 of the vibration position 111 (specifically, the first protruding structure 112), allowing the outer surface of the bone conduction vibrator 131 to contact the user's cheekbone 300 region, thereby allowing the mechanical vibration of the bone conduction vibrator 131 to directly act on the cheekbone 300. In another optional embodiment, the outer surface of the bone conduction vibrator 131 protrudes from the vibration surface 1111 of the vibration position 111 (specifically, the first protruding structure 112) and contacts the user's cheekbone 300 region, similarly allowing the mechanical vibration of the bone conduction vibrator 131 to directly act on the cheekbone 300.

[0071] It needs further explanation that "inner surface" refers to the surface facing the user's head, while "outer surface" refers to the surface away from the user's head.

[0072] In this embodiment, when viewed from a direction away from the head, the cross-sectional dimension of the first protrusion structure 112 is equal to the cross-sectional dimension of the retaining portion 11, meaning that the shape and size of the first protrusion structure 112 are consistent with the shape and size of the retaining portion 11. One reason for this design is that it allows for a more coherent connection between the sidewalls of the first protrusion structure 112 and the sidewalls of the retaining portion 11, ensuring that the tragus 206 does not feel uncomfortable when the sidewalls of the retaining portion 11 are close to or in contact with the tragus 206. Specifically, the first protrusion structure 112 and the retaining portion 11 are integrally formed, so the formation of the accommodating chamber 1121 is equivalent to the inner wall of the first protrusion structure 112 and the inner wall of the retaining portion 11 enclosing each other. Of course, other detachable connection methods are also possible, which are not limited here. In some other embodiments, when viewed from a direction away from the head, the cross-sectional dimension of the first protrusion structure 112 is smaller than the cross-sectional dimension of the retaining portion 11. This is equivalent to the formation of a stepped structure (not shown in the figure) between the outer wall of the first protrusion structure 112 and the inner surface of the retaining portion 11. The collision of this stepped structure with the tragus 206 may cause discomfort to the tragus 206. Therefore, when the cross-sectional dimension of the first protrusion structure 112 is smaller than the cross-sectional dimension of the retaining portion 11, the protrusion height of the first protrusion structure 112 needs to be greater than or equal to the height of the tragus 206 so that the retaining portion 11 has sufficient height to avoid the tragus 206 and prevent discomfort to the tragus 206.

[0073] Specifically, in medical terms, the surface of a user's cheekbone 300 is not completely flat; it has multiple protrusions and depressions, forming a complex structure with both convex and concave features. Therefore, a conforming structure (not shown in the figure) matching these protrusions and depressions is provided on the vibration surface 1111 of the first protrusion structure 112. When worn, the vibration surface 1111 of the first protrusion structure 112 engages with the outer surface of the user's cheekbone 300 region through the conforming structure. The physical locking between the conforming structure and these protrusions and depressions of the cheekbone 300 ensures a tight fit between the first protrusion structure 112 and the cheekbone 300 region, preventing displacement of the earphone body 1 during movement or head shaking, and ensuring that the vibration source is always aligned with the optimal transmission position. More specifically, when viewed from a direction away from the user's head, the first protrusion structure 112 has a geometric shape. In this embodiment, the first protrusion structure 112 is cylindrical, that is, the vibration surface 1111 of the first protrusion structure 112 is basically circular, and its edges have no sharp corners, so as to avoid pressure on the skin of the tragus 206 or other positions, and is suitable for long-term contact with the cheekbone 300 area.

[0074] Please refer to Figures 7-8In this embodiment, a through hole 113 is provided on the outer surface of the retaining part 11, which communicates with the interior of the first protruding structure 112. A first cover plate 114 is provided in the through hole 113, thereby separating the internal environment of the first protruding structure 112 from the external environment of the earphone body 1. The function of providing the through hole 113 and the first cover plate 114 is at least as follows: through the detachable engagement of the first cover plate 114 and the through hole 113, the bone conduction vibrator 131 disposed inside the first protruding structure 112 can be maintained, thereby avoiding the risk of needing to replace the entire retaining part 11 or even the entire earphone body 1 when the bone conduction vibrator 131 is damaged.

[0075] Please refer to Figure 6 In this embodiment, the rear end portion of the hook-shaped portion 12 includes the outer side surface of the rear end portion of the hook-shaped portion 12 and the inner side surface of the rear end portion of the hook-shaped portion 12. Figure 6 The middle EF segment can be considered as the outer surface of the posterior end of the hook-shaped part 12. Figure 6 The middle GH segment can be considered as the inner surface of the rear end portion of the hook-shaped portion 12. The inner surface of the rear end portion of the hook-shaped portion 12 has a third radius of curvature, and the outer surface of the rear end portion of the hook-shaped portion 12 has a fourth radius of curvature, with the third radius of curvature being larger than the fourth radius of curvature. Simultaneously, the cross-sectional area of ​​the rear end portion of the hook-shaped portion 12 gradually increases and then gradually decreases from the middle of the hook-shaped portion 12 towards the end away from the retaining portion 11. Therefore, in the wearing state, the inner surface of the rear end portion of the hook-shaped portion 12 is allowed to fit snugly against the back of the ear 100, and at this time, the inner surface of the rear end portion of the hook-shaped portion 12 extends along the back of the ear 100 towards the root of the ear 106. Meanwhile, the length of the inner side of the rear end portion of the hook-shaped portion 12 is less than the length of the outer side of the rear end portion of the hook-shaped portion 12. Therefore, when the outer side of the rear end portion of the hook-shaped portion 12 is connected to the inner side of the rear end portion of the hook-shaped portion 12, the outer side of the rear end portion of the hook-shaped portion 12 has sufficient length to be connected to the inner side of the rear end portion of the hook-shaped portion 12 in a meandering and curved manner. This corresponds to the aforementioned structural feature that the cross-sectional area of ​​the rear end portion of the hook-shaped portion 12 gradually increases and then gradually decreases from the middle of the hook-shaped portion 12 toward the end away from the retaining portion 11.

[0076] A second protrusion structure 121 is provided on the inner surface of the rear end of the hook-shaped part 12. The second protrusion structure 121 protrudes from the inner surface of the rear end of the hook-shaped part 12. When worn, the inner surface of the second protrusion structure 121 abuts against the temporal bone 301. Under the leverage of the headband part 2 (specifically the connection between the headband part 2 and the headphone body 1), the vibration surface 1111 of the first protrusion structure 112 abuts against the cheekbone 300. Specifically, before the second protrusion structure 121 is set, the inner surface of the rear end of the hook-shaped part 12 abuts against the temporal bone 301. After the second protrusion structure 121 is set, the inner surface of the second protrusion structure 121 abuts against the temporal bone 301, causing the rear end of the hook-shaped part 12 to move away from the user's head. The connection between the headband part 2 and the headphone body 1 acts as a fulcrum, causing the first protrusion structure 112 at the front end of the hook-shaped part 12 to move in the opposite direction to the movement of the second protrusion structure 121 at the rear end of the hook-shaped part 12. That is, the first protrusion structure 112 will move closer to the user's head, making the fit between the first protrusion structure 112 and the cheekbone 300 higher, thereby allowing the bone conduction oscillator 131 to transmit the vibration energy generated during operation to the cheekbone 300 more effectively.

[0077] Please refer to Figure 8 , Figure 8 This is an exploded structural diagram of the earphone body 1. More specifically, the inner wall of the second protrusion structure 121 and the inner wall of the rear end of the hook-shaped part 12 enclose the mounting chamber 122, which also includes a battery 14, a PCB 15, and a wire 16. The battery 14 and PCB 15 are disposed in the mounting chamber 122. One end of the wire 16 is connected to the PCB 15, and the other end of the wire 16 is connected to the bone conduction vibrator 131. One reason for placing the battery 14 and PCB 15 in the mounting chamber 122 inside the rear end of the hook-shaped part 12 is to offset the total weight of the retaining part 11 and the first protrusion structure 112, balancing the overall weight of the earphone body 1 through the lever principle, and avoiding the risk of slippage caused by excessive weight concentration in the retaining part 11 during movement. An opening 123 is provided on the outer surface of the rear end of the hook-shaped part 12, which communicates with the mounting chamber 122. A second cover plate 124 is disposed in the opening 123, thereby separating the mounting chamber 122 from the internal environment and the earphone body 1. The function of setting the opening 123 and the second cover plate 124 is at least as follows: through the detachable cooperation between the second cover plate 124 and the opening 123, the battery 14 and PCB 15 set in the installation chamber 122 can be routinely maintained, thereby avoiding the risk of having to replace the entire hook part 12 or even the entire earphone body 1 when the battery 14 is dead or the PCB 15 is damaged.

[0078] Furthermore, it may also include a memory metal wire (not shown in the figure), which is located inside the hook-shaped portion 12. The memory metal wire is used at least to provide pre-pressure for the vibration position 111 of the retaining portion 11, so that the vibration surface 1111 contacts the cheekbone 300 area. On the other hand, the memory metal wire is also used to automatically restore the preset shape after the headphone body 1 is deformed by force, so that the hook-shaped portion 12 fits tightly against the auricular curve between the back of the user's ear and the head, and avoids the headphone body 1 from loosening or slipping due to differences in head shape or ear shape.

[0079] Please refer to Figures 8-11 In this embodiment, a rotating mounting portion 125 is provided on the outer side of the hook-shaped portion 12, specifically at the middle of the hook-shaped portion 12, and the end of the head beam portion 2 is rotatably connected to the rotating mounting portion 125. A first abutting portion 1251 is provided on the side of the rotating mounting portion 125 near the holding portion 11, such as... Figure 8 As shown, a first reference line L1 passes through the connection between the rotating mounting part 125 and the headband part 2, and is parallel to the user's sagittal plane. When the headband part 2 rotates by a first angle α1 from the position of the first reference line L1 towards the first abutment part 1251 with the aforementioned connection point as the center, the headband part 2 abuts against the first abutment part 1251. A third reference line L3 passes through the headband part, and the extension direction of the third reference line L3 is consistent with the extension direction of the headband part. The angle between the third reference line L3 and the first reference line L1 is the aforementioned first angle α1. Essentially, the function of the first abutment part is to limit the degree to which the headband part 2 rotates forward, preventing it from detaching from the user's head when rotating forward. Specifically, based on the structural characteristics of the human skull, the first angle α1 ranges from 0° to 45°, meaning the headband part 2 can rotate forward a maximum of 45°.

[0080] Similarly, a second abutment 1252 is provided on the side of the rotating mounting part 125 away from the holding part 11. A second reference line L2 passes through the connection between the rotating mounting part 125 and the headband part 2 and is parallel to the user's sagittal plane. When the headband part 2 rotates by a second angle a2 from the position of the second reference line L2 towards the second abutment 1252 with the aforementioned connection as the center, the headband part 2 abuts against the second abutment 1252. A fourth reference line L4 passes through the headband part, and the extension direction of the fourth reference line L4 is consistent with the extension direction of the headband part. The angle between the fourth reference line L4 and the second reference line L2 is the aforementioned second angle a2. In essence, the function of the second abutment 1252 is to limit the degree of rotation of the headband part 2 towards the back of the head, preventing the headband part 2 from detaching from the user's head when rotating towards the back of the head. Specifically, based on the structural characteristics of the human skull, the range of the second angle a2 is between 0° and 90°, that is, the headband part 2 can rotate a maximum of 90° towards the back of the head.

[0081] It should be further explained that the aforementioned first reference line L1, second reference line L2, third reference line L3 and fourth reference line L4 are only used to describe the position of the head beam 2, and there is no difference between them.

[0082] Specifically, in this embodiment, the headband 2 is generally arc-shaped, and the rotating mounting part 125 includes a first sidewall 1253 and a second sidewall 1254 spaced apart. The ends of the headband 2 are rotatably connected to the first sidewall 1253 and the second sidewall 1254 respectively via a hinge 21. The distance between the first sidewall 1253 and the second sidewall 1254 is slightly greater than the thickness of the headband 2, so as to allow the headband 2 to have enough space to rotate on the first sidewall 1253 and the second sidewall 1254, avoiding the risk of the headband 2 getting stuck due to the small distance between the first sidewall 1253 and the second sidewall 1254.

[0083] More specifically, it also includes a groove structure 1255, which is disposed on the outer surface of the hook-shaped portion 12. The groove structure 1255 further includes a first groove 12551 and a second groove 12552 that are interconnected. The first groove 12551 is entirely located between the first sidewall 1253 and the second sidewall 1254. A portion of the second groove 12552 is located between the first sidewall 1253 and the second sidewall 1254, and another portion extends away from the first sidewall 1253 / second sidewall 1254. The width of the first groove 12551 and the width of the second groove 12552 are slightly larger than the width of the end of the headband portion 2, thereby allowing the end of the headband portion 2 to have space to rotate within the first groove 12551 and the second groove 12552. In this embodiment, the bottom surface of the first groove 12551 is substantially semi-circular, and the end of the bottom surface of the first groove 12551 near the retaining part 11 can serve as the aforementioned first abutment part 1251. The bottom surface of the second groove 12552 is substantially planar, and the bottom surface of the second groove 12552 can serve as the aforementioned second abutment part 1252. One reason for providing the first groove 12551 and the second groove 12552 is that when the end of the headband 2 is too long, the first groove 12551 and the second groove 12552 can provide the end of the headband 2 with a space that allows for smooth rotation and avoidance. Therefore, in other embodiments, when the end of the headband 2 is short enough, the first groove 12551 and the second groove 12552 may not be provided, and this is not a limitation here.

[0084] It should be further explained that, in other embodiments, the shape of the first groove 12551 is not limited to a semi-circle, but can also be square or other shapes. Similarly, in this embodiment, the second groove 12552 is generally elongated, but in other embodiments, the second groove 12552 can also be square. The specific shapes of the first groove 12551 and the second groove 12552 are not limited here; this embodiment is only provided as a preferred solution.

[0085] Please refer to Figure 12 , Figure 12 This is an exploded structural diagram of the headband. In this embodiment, the headband 2 includes a headband cover 22 and a metal headband 23. The headband cover 22 is fitted onto the surface of the metal headband 23. Both ends of the metal headband 23 are rotatably connected to two rotating mounting parts 125 via the aforementioned hinge 21. Similarly, both ends of the headband cover 22 are also rotatably connected to the two rotating mounting parts 125 via the aforementioned hinge 21. The functions of the metal headband 23 include, but are not limited to: 1. Enabling the headband 2 to withstand frequent bending and stretching, preventing breakage or deformation after prolonged use. 2. Providing moderate clamping force, ensuring stable wearing (e.g., preventing slippage during exercise) while avoiding excessive pressure on the user's head. Specifically, in this embodiment, the metal headband 23 is made of stainless steel. One reason for using stainless steel is its strong corrosion resistance, preventing rust from forming on the metal headband 23 after prolonged use in humid environments (e.g., running, fitness, etc.).

[0086] The working principle of this utility model is described below to facilitate a better understanding of it:

[0087] In the first wearing method, such as Figure 13As shown, the headband 2 is hung on the head. The hanging angle of the headband 2 can be rotated up to 45° towards the front of the head or up to 90° towards the back of the head, with the coronal plane of the human body as the center, until a comfortable position is found for the user. At this time, the two earphone bodies 1 are held on both sides of the user's head by the metal headband 23. The hook-shaped part 12 is hung between the back of the user's ear and the head, and the position of the second protruding structure 121 is adjusted so that the second protruding structure 121 fits against the temporal bone 301 area. The position of the retaining part 11 is adjusted so that the first protruding structure 112 fits against the cheekbone 300 area. When music is played, the bone conduction vibrator 131 converts the audio electrical signal into a mechanical vibration signal. The bone conduction vibrator 131 contacts the user's zygomatic bone 300 area through the first protrusion structure 112, and vibrates the zygomatic bone 300 to make it vibrate synchronously. The vibration of the zygomatic bone 300 transmits this mechanical vibration signal directly to the cochlea, bypassing the external auditory canal and tympanic membrane. The cochlea converts the mechanical vibration signal into an electrical signal, which is finally transmitted to the brain by the auditory nerve.

[0088] In the second wearing method, firstly, the hook-shaped part 12 of the headphone body 1 is hung between the back of the user's ear and head. Then, the headband 2 is hung on the head, and the relative rotation angle of the headband 2 is adjusted appropriately. Other specific steps are the same as in the first wearing method, and will not be repeated here.
