[0002] Hearing aids are designed for people with mild to moderate hearing loss, with the elderly being the primary user group. Currently, most hearing aids on the market are in-ear or on-ear models.

[0003] In-ear headphones achieve good sound quality through air conduction, but they need to be inserted into the ear canal. This can cause discomfort for middle-aged and elderly people after prolonged use, and it is also difficult to learn how to wear them correctly. Incorrect wearing can easily cause the headphones to fall out. While over-ear headphones are relatively easy to wear, they require a curved ear hook to rest on the upper and back of the ear. Since everyone's ear size and shape are different, it is difficult to achieve a perfect fit. Furthermore, wearing an ear hook can interfere with other activities such as wearing glasses.

[0004] This shows that current hearing aids are not comfortable enough to meet users' actual needs. Utility Model Content

[0049] In order to make the technical problems solved by the utility model, the technical scheme adopted and the technical effects reached more clear, the technical scheme of the utility model embodiments will be further described in detail below with reference to the drawings. Obviously, the described embodiments are only some of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the utility model.

[0050] In the description of the utility model, unless explicitly defined and limited, the terms "connected", "fixed" should be understood broadly, for example, it can be fixedly connected, or detachably connected or integrated; it can be mechanically connected, or electrically connected; it can be directly connected, or indirectly connected through an intermediate medium, or the internal communication of two elements or the interaction relationship between two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0051] In the utility model, unless explicitly defined and limited, the first feature "on" or "under" the second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, the first feature "on", "above" and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature "under", "below" and "under" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0052] At present, some people have hearing loss. Among them, people inevitably encounter hearing loss problems after reaching middle and old age, and with the acceleration of the global population aging trend, the number of hearing loss population will continue to grow. Although the traditional hearing aid can help the hearing impaired, it has problems such as high price, low coverage of fitting channel and poor comfort. In order to improve the user experience, some earphone manufacturers combine the hearing aid and the Bluetooth earphone into one, and produce the auxiliary hearing earphone. The auxiliary hearing earphone is a special sound enhancement type earphone, which is suitable for people with mild to moderate hearing loss, and is also suitable for people whose hearing temporarily decreases due to special reasons (such as long-term exposure to noise environment).

[0053] However, the current auxiliary hearing earphone still has deficiencies in wearing comfort and use convenience, and it is difficult to meet the actual needs of users. The current auxiliary hearing earphone can be divided into bone conduction and air conduction according to the principle. The bone conduction earphone transmits sound by vibrating the skull, and long-term wearing may cause slight numbness or discomfort of the head, and the sound leakage is serious, and the sound quality effect is poor. The air conduction earphone includes in-ear wearing and over-ear wearing. The in-ear earphone needs to be inserted into the ear canal, but long-term wearing will cause discomfort, and the elderly are more sensitive to the ear, and the in-ear wearing is not comfortable, and for the elderly, it is more difficult to master the in-ear wearing method, and if the user fails to successfully insert the earphone into the ear canal, the earphone is easy to directly fall and lose. The over-ear earphone needs to be hung on the upper and rear sides of the ear by using the ear hook, and the ear hook has strong pressure on the ear, and the ear hook needs to occupy the space on the upper side of the ear, and for the user who needs to wear glasses (such as presbyopia glasses, myopia glasses, sunglasses, AR glasses), the glasses legs will interfere with the ear hook, and the glasses cannot be worn well. It can be seen that the auxiliary hearing earphone in the related art still has deficiencies in wearing comfort and use convenience, and needs to be improved.

[0054] Therefore, in order to solve the problems in the related art, the present application provides a head bow earphone, which can be used as an auxiliary hearing earphone, of course, the head bow earphone can also be used for listening to music, etc. The earphone has low wearing learning cost and high wearing comfort, and for the hearing impaired population, the earphone has better wearing comfort and is more convenient.

[0055] The head bow earphone of the present application uses the elastic force of the head bow to make the two bin bodies located at the rear sides of the two ears abut against the positions of the two sides of the skull (the positions near the mastoid process), thereby providing wearing stability. Compared with the conventional ear clamping earphone, the head bow earphone can reduce the ear clamping feeling, improve the wearing comfort, and is easy to wear, and can avoid the situation that the single earphone is lost.

[0056] Please refer to Figures 1 to 13 The head bow earphone of the present application includes a head bow 10, two bin bodies and two earphone heads.

[0057] Please refer to Figure 1 、 Figure 4 、 Figure 5 The head bow 10 is bent, and the inner side of the head bow 10 forms a wearing space for accommodating part of the head or neck of the user. The two ends of the head bow 10 are a first end and a second end, and the first end and the second end are spaced apart from each other to form an opening of the wearing space.

[0058] The first earphone head 41 is connected with the first cavity body 21 through the first wire bridge 31, and the second earphone head 42 is connected with the second cavity body 22 through the second wire bridge 32. The first earphone head 41, the first wire bridge 31 and the first cavity body 21 define a first ear accommodating space 100 for accommodating the ear 90, and the second earphone head 42, the second wire bridge 32 and the second cavity body 22 define a second ear accommodating space 200 for accommodating the ear 90. The first earphone head 41 and the second earphone head 42 are both provided with sound generating units, and the first wire bridge 31 and the second wire bridge 32 not only serve as the connection between the earphone head and the cavity body, but also can be internally arranged with wires to realize the electrical connection between the electronic devices in the earphone head and the electronic devices in the cavity body.

[0059] The head bow 10 is an elastic member, and the head bow 10 has a normal state. When no external force acts on the head bow 10, the head bow 10 remains in the normal state (as shown in Figures 1 to 3 ). The head bow 10 can be deformed by being stretched under the action of an external force (as shown in Figure 4 , Figure 5 ), so as to be adjusted from the normal state to a stretched state, so that the interval between the first cavity body 21 and the second cavity body 22 is increased, that is, the opening of the wearing space is increased. At this time, the first cavity body 21 and the second cavity body 22 have a tendency to approach each other under the action of the elasticity of the head bow 10.

[0060] Referring to Figure 1 , Figures 3 to 6 , the first cavity body 21 has a first supporting surface 211 on the inner side, and the second cavity body 22 has a second supporting surface 221 on the inner side. The inner side of the first cavity body 21 and the second cavity body 22 refers to the side of the first cavity body 21 and the second cavity body 22 that faces the head of the user when the head bow type earphone is worn by the user. The first supporting surface 211 and the second supporting surface 221 are respectively used for abutting against the head, and are generally used for abutting against the position near the mastoid process and the temporal bone. The temporal bone refers to the part of the skull behind the ear.

[0061] Referring to Figures 7 to 10 , when the head bow type earphone of the present application is worn, the first earphone head 41 and the second earphone head 42 are located on the front side of the ear 90, the first cavity body 21 and the second cavity body 22 are located on the rear side of the ear 90, the head bow 10 is deformed by being stretched, the first cavity body 21 and the second cavity body 22 have a tendency to approach each other by the elasticity of the head bow 10, and the first supporting surface 211 and the second supporting surface 221 are respectively abutted against the positions near the left and right temporal bones and the mastoid processes, so that the two cavity bodies behind the ears are clamped on the head to provide wearing stability.

[0062] The head-arc earphone of the present application, when worn, cleverly uses the elastic force of the head-arc 10 to make the first and second housings 21 and 22 located at the back of the left and right ears tend to approach each other, thereby abutting against the mastoid process and the position near the temporal bone on both sides of the head, achieving stable wearing of the earphone. This design can avoid pressing the inner ear canal and reduce the pressure on the external ear, greatly improving the wearing comfort. At the same time, the earphone does not occupy the space above the ear 90 when worn, which is convenient for users wearing glasses, and the glasses legs can be naturally hung on the upper side of the ear 90.

[0063] The head-arc earphone of the present application is different from the traditional clip-on earphone. The clip-on earphone in the related art is generally two independent earphone structures, each of which is worn by clamping the ear 90 with the front and rear parts. For users who are sensitive to the ear 90 or wear it for a long time, it is easy to feel uncomfortable when clamping the ear. The head-arc earphone of the present application uses the elastic force of the head-arc 10 to clamp the two housings near the mastoid process and the temporal bone, providing the main stability of wearing, so the requirement for clamping force can be reduced or even eliminated, effectively reducing the discomfort of clamping the ear and improving the comfort of long-term wearing. Compared with the conventional clip-on earphone, the interval between the first housing 21 and the first earphone head 41 and the interval between the second housing 22 and the second earphone head 42 can be set larger. In the ideal wearing state, the two housings can not contact or only slightly contact the ear 90 of the user, effectively eliminating or reducing the feeling of oppression on the ear 90, and are particularly suitable for users who need to wear the earphone for a long time and are sensitive to the ear 90.

[0064] In the design, the areas of the first and second support surfaces 211 and 221 can be adjusted according to the wearing experience requirements, so that the first and second housings 21 and 22 can be comfortably felt against the left and right sides of the skull, reducing the discomfort of the head.

[0065] The head-arc 10 connects the left and right earphone bodies, reducing the risk of losing a unilateral earphone for middle-aged and elderly people. In addition, the head-arc 10 has multiple choices in the wearing method. As shown in Figure 9 、 Figure 10 indicated, the head-arc 10 can be located at the back of the head or the back of the neck when worn, generally in a suspended state. Of course, the head-arc 10 can also be designed to generally fit on the back of the head or the neck when worn by the user, providing a certain supporting force.

[0066] Optionally, the head-arc earphone is an open-wearing earphone, and the first and second earphone heads 41 and 42 are used to be worn in the concha cavity, Figure 14The cymba concha is shown. The skin of the middle-aged and elderly is relatively sensitive, and open wearing does not block the ear canal, avoiding many uncomfortable feelings. The earphone head is located in the cymba concha, which is closer to the position of the human ear naturally receiving sound, optimizes the sound propagation path, and can adjust the sound effect according to the hearing characteristics of the middle-aged and elderly, improve the clarity and intelligibility of the sound, and meet their hearing compensation needs.

[0067] Optionally, the first and second housings 21 and 22 are used to wear on the space behind the ear 90. And the first and second wire bridges 31 and 32 are used to wear on the left side of the left ear and the right side of the right ear respectively. The first and second housings 21 and 22, the first and second wire bridges 31 and 32 all avoid the space on the top of the ear 90, and do not affect the wearing of glasses. Figure 15 The position relationship between the two earphone heads and the antihelix and cymba concha of the ear in the wearing state is shown.

[0068] In an embodiment, in order to balance the universality, wearing comfort and stability of the head-arc earphone, the first and second wire bridges 31 and 32 are both elastic structures, that is, the first and second wire bridges 31 and 32 have a springback property.

[0069] Optionally, the head-arc 10 is internally provided with a memory metal, the first wire bridge 31 is internally provided with a memory metal, and the second wire bridge 32 is internally provided with a memory metal. The memory metal inside the head-arc 10 can automatically restore to the preset shape after being deformed under stress. This means that the head-arc 10 can better adapt to the head size and shape of different users, whether the user has a larger or smaller head circumference, a more comfortable wearing experience can be obtained. The memory metal inside the first and second wire bridges 31 and 32 can be self-adapted to a certain extent according to the shape and position of the user's ear 90. The thickness, shape and position of different people's ears 90 are different, and the characteristics of the memory metal make the wire bridge better fit the ear 90, reduce the pressure on the ear 90, and further improve the wearing comfort.

[0070] The first wire bridge 31 and the second wire bridge 32 are elastic, so that when the user wears the head-hugging earphone, the opening between the first earphone head 41 and the first housing 21 and the opening between the second earphone head 42 and the second housing 22 can be opened, thereby facilitating the ear 90 to be clamped between the earphone head and the housing to achieve wearing, and improving the wearing convenience. In addition, the thickness of the ears 90 of different people is different, and the wire bridge is designed as an elastic body, which can adapt to different ear thicknesses. It can be understood that the wire bridge has a rebounding property, which connects the earphone head and the housing, but the relative position and distance of the earphone head and the housing are appropriate, and there is no obvious ear clamping feeling on the human ear, but only the wire bridge limits the up and down position of the housing when the earphone is worn, so that the two housings can be clamped on the skull position, and the wire bridge plays a limiting role in avoiding the housing from falling. In an ideal state, the first earphone head 41 and the second earphone head 42 are located in the concha cavity, and the first housing 21 and the second housing 22 are in a state of just contacting the skin of the ear 90.

[0071] In other embodiments, the first wire bridge 31 and the second wire bridge 32 can also be ordinary structures without rebounding properties or with very weak rebounding properties.

[0072] In an embodiment, when the head-hugging earphone is in a wearing state, the first housing 21 and the second housing 22 are located at the back of the left and right ears 90, respectively. Referring to Figure 1 、 Figure 3 、 Figure 5 、 Figure 6 The first housing 21 has the first supporting surface 211 described above, and also has a first contact surface 212. The first supporting surface 211 is located on the side of the first housing 21 close to the second housing 22, and the first contact surface 212 is located on the side of the first housing 21 close to the first earphone head 41. The second housing 22 has the second supporting surface 221 described above, and also has a second contact surface 222. The second supporting surface 221 is located on the side of the second housing 22 close to the first housing 21, and the first contact surface 212 is located on the side of the first housing 21 close to the first earphone head 41.

[0073] When the head-hugging earphone is in a wearing state, the first supporting surface 211 and the second supporting surface 221 are used to be clamped on both sides of the skull, so that the first housing 21 and the second housing 22 are supported from both sides of the head to provide wearing stability. When the head-hugging earphone is in a wearing state, the first contact surface 212 and the second contact surface 222 are used to contact the ear 90 to provide a limiting effect, so that the entire head-hugging earphone is not easy to slide down, and the two earphone heads can be more stably maintained in the two concha cavities, and the two housings can be stably maintained at the position near the skull and the mastoid process.

[0074] Optionally, as Figure 5 、 Figure 6 、 Figure 12For example, in order to improve wearing comfort, the first contact surface 212 and the second contact surface 222 are designed as arc surfaces, which can well fit the shape of the back side of the outer ear and improve wearing comfort, and can also increase the contact area between the earpiece and the back of the ear to increase friction and achieve good limiting effect.

[0075] Optionally, the first support surface 211 and the second support surface 221 are substantially flat surfaces or arc surfaces.

[0076] In an embodiment, the first earpiece 21 and the second earpiece 22 are flat in the thickness direction thereof, where the thickness direction of the earpiece refers to the direction perpendicular to the plane in which the first wire bridge 31 and the second wire bridge 32 are located. The first earpiece 21 has a first upper surface 213 and a first lower surface on both sides thereof in the thickness direction, and the first upper surface 213 and the first lower surface are substantially parallel, and the first upper surface 213 and the first lower surface are flat surfaces or slightly concave surfaces concave to the inside of the earpiece. Similarly, the second earpiece 22 has a second upper surface 223 and a second lower surface on both sides thereof in the thickness direction, and the second upper surface 223 and the second lower surface are substantially parallel, and the second upper surface 223 and the second lower surface are flat surfaces or slightly concave surfaces concave to the inside of the earpiece. It can be understood that such design of flat or slightly arc surfaces on both sides of the earpiece in the thickness direction is more convenient for the elderly to hold the earpiece with the thumb and the index finger on the upper surface and the lower surface of the earpiece, thereby facilitating the operation of picking up and wearing the earphone.

[0077] In other embodiments, the first earpiece 21 and the second earpiece 22 can also have other shapes.

[0078] In an embodiment, please refer to Figure 2 , Figure 3 , Figure 9 , Figure 13 The first earpiece 21 and the second earpiece 22 are inclined to the upper side of the head bow 10 relative to the head bow 10. That is, if the bottom surface of the head bow 10 is placed on the desktop, the first earpiece 21 and the second earpiece 22 will be inclined upward relative to the desktop; or, if the bottom surfaces of the first earpiece 21 and the second earpiece 22 are placed on the desktop, the head bow 10 will be inclined upward relative to the desktop.

[0079] In this embodiment, the two earpieces are inclined upward relative to the head bow 10, so that when the head bow earphone is in the wearing state, as shown in Figure 9As shown, the first housing 21 and the second housing 22 are inclined downward from the front end close to the ear 90 to the rear end away from the ear 90, so that the first support surface 211 and the second support surface 221 can be well fitted to the mastoid process and the temporal bone, and the first housing 21 and the second housing 22 on the rear side of the two ears 90 can be well fitted to the skull on both sides, and the wearing stability is high. Furthermore, it is continued to refer to Figure 9 , Figure 10 In the wearing state, the housings are inclined downward from the front to the rear, and the head arch 10 is located lower, approximately on the rear side of the neck or the rear side of the back of the head. At this time, the head arch 10 has a certain interval with the skin on the head and the neck, and the head arch 10 is approximately suspended, reducing the compression of the head arch 10 on the head and the neck, and reducing the interference of the head arch 10 with the collar and the like. During the process of standing up or sitting down of the user, the head arch 10 is less likely to press the head or the neck.

[0080] In other embodiments, the head arch earphone in the wearing state can also be fitted to the rear side of the neck or the head. In other embodiments, the first housing 21 and the second housing 22 are approximately horizontal when the head arch earphone is in the wearing state.

[0081] Since the skull outside the left ear and the right ear (temporal bone and mastoid process position) of the human head is not vertically downward, in order to enable the head arch earphone of the present application to achieve a better wearing effect, the shape of the first housing 21 and the second housing 22 is optimized.

[0082] In an embodiment, in order to enable the two housings to be better fitted to the temporal bone and the mastoid process position, it is referred to Figure 3 In the normal state of the head arch 10, the first support surface 211 and the second support surface 221 are configured to be inclined outward from bottom to top. Exemplarily, the first earphone head 41 and the first housing 21 are located on the left side of the head arch earphone, and the second earphone head 42 and the second housing 22 are located on the right side of the head arch earphone. The first support surface 211 is in a state of being inclined leftward and spread from bottom to top, and the second support surface 221 is in a state of being inclined rightward and spread from bottom to top. In this way, the first support surface 211 on the left side can be well fitted to the temporal bone position on the left side of the head, and the second support surface 221 can be well fitted to the temporal bone position on the right side of the head.

[0083] Among them, in the normal state of the head arch earphone, that is, the elastic head arch 10 is in the natural state, as shown in Figure 3 As shown, the plane tangent to the inner end of the first housing 21 and perpendicular to the head arch 10 is the first plane S1, the plane tangent to the inner end of the second housing 22 and perpendicular to the head arch 10 is the second plane S2, and the reference plane is S0, which is the plane tangent to the bottom of the head arch 10. S1 and S2 are perpendicular to S0.

[0084] Optionally, in the case that the head arch 10 of the head arch earphone is parallel to the ground, or in the case that the bottom of the head arch 10 of the head arch earphone is placed on the desktop, the first support surface 211 is outwardly inclined relative to the first plane, and the second support surface 221 is outwardly inclined relative to the second plane. Referring to Figure 11 , the included angle a1 between the first support surface 211 and the first plane is 3 degrees ≤ a1 ≤ 13 degrees; similarly, the included angle a2 between the second support surface 221 and the second plane is 3 degrees ≤ a2 ≤ 13 degrees. It can be understood that through the setting of a1 and a2, the first cavity body 21 and the second cavity body 22 can be more comfortably and well fitted to the skull position on the back side of the ear 90, and the wearing comfort and stability are improved.

[0085] Optionally, it has been verified that a1 and a2 are more suitable between 5 degrees and 10 degrees, and are better fitted to the skull.

[0086] Optionally, in the case that the head arch 10 is in a normal state and the head arch earphone is in an unworn state, the first support surface 211 and the second support surface 221 are designed to be outwardly inclined from front to back. Among them, the first cavity body 21 is connected with the first end portion of the head arch 10, the inner side of the first end portion is tangent to the third plane, the first support surface 211 and the third plane form an included angle b1, 10 degrees ≤ b1 ≤ 30 degrees (as shown in Figure 12 ). The second cavity body 22 is connected with the second end portion of the head arch 10, the inner side of the second end portion is tangent to the fourth plane, and the second support surface 221 and the fourth plane form an included angle b2, 10 degrees ≤ b2 ≤ 30 degrees (not shown in the figure). Figure 12 The third plane S3 is shown in the middle.

[0087] It can be understood that through the parameter limitation of a1 and b1, the angle of the first support surface 211 can be limited from two dimensions, so that the first support surface 211 can be well fitted to the left skull position. Through the parameter limitation of a2 and b2, the angle of the second support surface 221 can be limited from two dimensions, so that the second support surface 221 can be well fitted to the left skull position.

[0088] In an embodiment, the first wire passing bridge 31 and the second wire passing bridge 32 are designed to be inclined relative to the head arch 10, referring to Figures 7 to 9 , in the case that the head arch earphone is in a worn state, the first wire passing bridge 31 and the second wire passing bridge 32 present a downwardly inclined state from front to back. Compared with the scheme that the wire passing bridge extends horizontally backward, in this embodiment, the wire passing bridge is downwardly inclined from the front side of the ear 90 to the back side of the ear 90, so that the first cavity body 21 and the second cavity body 22 can be better fitted to the skull position.

[0089] Exemplarily, the head arch 10 is parallel to a fifth plane, the first wire-crossing bridge 31 is parallel to a sixth plane, the second wire-crossing bridge 32 is parallel to a seventh plane, the sixth plane and the fifth plane form an included angle γ1, and the seventh plane and the fifth plane form an included angle γ2; 15 degrees ≤ γ1 ≤ 55 degrees, 15 degrees ≤ γ1 ≤ 55 degrees. Figure 13 The fifth plane S5 and the sixth plane S6 are shown in the figure.

[0090] In other embodiments, the sixth plane is parallel to the fifth plane, and the seventh plane is parallel to the fifth plane.

[0091] In an embodiment, in order to improve wearing comfort, the width of the first opening for the ear 90 to enter between the first earphone head 41 and the first warehouse body 21 and the width of the second opening for the ear 90 to enter between the second earphone head 42 and the second warehouse body 22 are controlled to be between 3mm and 10mm.

[0092] Optionally, the first wire-crossing bridge 31 has a normal state, when the first wire-crossing bridge 31 is in the normal state, the first earphone head 41 and the first warehouse body 21 form a first opening, the size of the first opening is d1, 3mm ≤ d1 ≤ 10mm; the second wire-crossing bridge 32 has a normal state, when the second wire-crossing bridge 32 is in the normal state, the second earphone head 42 and the second warehouse body 22 form a second opening, the size of the second opening is d2, 3mm ≤ d1 ≤ 10mm. Wherein, it is found through measurement that the thickness of human ear is generally about 3mm, and the ear thickness at the position of the antihelix of human ear generally does not exceed 10mm, and the cross section at the position of the antihelix and the ear clamp cavity is a triangular shape, as shown in the figure. Figure 12 Therefore, in order to enable the earphone to be well worn on the ear and not to have a significant ear clamping feeling but not to be loose, the opening distance d1, d2 is set to be between 3mm and 10mm.
