[0002] Headphones are one of the most common types among various earphone types. When in use, the earphones are worn on the head, and their structure completely covers the ears, so they perform well in terms of sound insulation and noise reduction. However, this wearing method is likely to cause the situation that since the headphone usually is equipped with earcups, after the earcups cover the ears, the ears will not be breathable. After long-term use, especially when the temperature is relatively high, the user's ears will feel stuffy and uncomfortable, so it is easy to affect the use experience. In addition, the ears are prone to sweating after wearing the earphones for a long time, and the sweat on the ears will further reduce the service life of the ear pads.

[0003] Currently, although there are some open-back over-ear headphones on the market, which mainly solve the stuffy problem by opening ventilation holes on the earphones. However, in this design, when wearing, it is easy for the external wind to enter the earphones to form wind noise, thus affecting the sound quality effect of the earphones, and further affecting the use experience. Moreover, for open-back over-ear headphones, in low-temperature weather, the ears are exposed, which is likely to make the ears feel very cold, and will also affect the use experience.

[0004] Therefore, for open-back over-ear headphones, how to solve the wind noise problem, improve the warmth retention performance in cold weather, and improve the signal-to-noise ratio (SNR) and noise reduction effect in a noisy environment are all problems that need to be considered and solved.

Detailed implementation manners

[0036] The following further elaborates on the detailed implementation manners of the present invention with reference to the accompanying drawings. It should be understood that the detailed implementation manners described herein are only for the purpose of illustrating and explaining the present invention, and are not intended to limit the present invention.

[0037] For the convenience of those skilled in the art to understand, the following describes the specific implementation process of the technical solutions in the present application through multiple embodiments.

[0038] Embodiment 1:

[0039] Please refer to Figure 1 - Figure 8 , a pair of on-ear OWS open headphones in this embodiment includes: a head beam 10 and two ear bodies 20.

[0040] The two ear bodies 20 are respectively connected to both sides of the head beam 10. At least one ear body 20 includes an ear frame 21, a sound generating unit 22, and a rotating cover 23; the ear frame 21 is circular to form a receiving cavity 201 for receiving the ears inside; the sound generating unit 22 is installed on the side of the ear frame 21 away from the ears, and a part of the structure of the sound generating unit 22 is located in the receiving cavity 201. There is at least one ventilation hole 202 between the sound generating unit 22 and the ear frame 21. The ventilation hole 202 is connected to the receiving cavity 201, and the side of the ventilation hole 202 is a plate structure. The sound generating unit 22 and the ear frame 21 are connected through the plate structure, and the plate structure shields the receiving cavity 201; the rotating cover 23 is rotatably installed on the ear frame 21 and opens or closes the ventilation hole 202 when rotating, so as to switch the earphone to the open mode or the closed mode.

[0041] Therefore, in this embodiment, the rotation of the rotating cover 23 can open or close the ventilation hole 202 to switch the earphone mode. Among them, when the ventilation hole 202 is opened, the earphone is switched to the open mode, at this time, the ears can breathe, effectively solving the problem of ear stuffiness; when the ventilation hole 202 is blocked, at this time, the ventilation hole 202 is closed, and the earphone is switched to the closed mode, which can form a sealed environment around the ears, effectively reducing the sound leakage of the earphone and reducing wind noise, thereby improving the acoustic output performance and noise reduction effect of such open earphones. At the same time, it can prevent the ears from being exposed to the outside and getting cold when the user wears the earphone in low-temperature weather, playing a certain role in keeping warm; therefore, this application provides two usage modes, which can be switched at will to adapt to the needs of different users and different environments, and is very convenient and flexible to use, effectively improving the usage experience.

[0042] In this embodiment, there are two ventilation holes 202 between the sound generating unit 22 and the ear frame 21, and the ventilation holes 202 are symmetrically arranged around the sound generating unit 22, and the ventilation holes 202 are in a fan-shaped structure, with good ventilation effect. Of course, in other embodiments, the shape, number and arrangement of the ventilation holes 202 are not limited.

[0043] In this embodiment, the side of the sound generating unit 22 away from the accommodation cavity 201 is provided as a boss 212; the rotary cover 23 includes a cover body 232 and a first shielding piece 233; the cover body 232 is in a cylindrical shape, and has a mounting groove 203 on the side facing the sound generating unit 22. The structure of the mounting groove 203 corresponds to that of the boss 212. By fitting the mounting groove 203 onto the boss 212, when the cover body 232 is mounted onto the boss 212, the cover body 232 can rotate on the boss 212; and the first shielding piece 233 is in a fan-shaped structure and is mounted on the side wall of the cover body 232. Specifically, there are two first shielding pieces 233 on the cover body 232, and each first shielding piece 233 corresponds to a ventilation hole 202 respectively. By rotating the cover body 232, the first shielding piece 233 can be driven to open or close the ventilation hole 202, and thereby the earphone is switched to the open mode or the closed mode.

[0044] It should be noted that the boss 212 is the tail structure of the sound generating unit 22 and is integrally formed with the sound generating unit 22. Of course, in other embodiments, the boss 212 can be set as a structure extending from the ear hook 21 to the middle of the ear hook 21, and a position is provided here to mount the sound generating unit 22 and other components.

[0045] Furthermore, a connection hole 204 is provided at the end face of the boss 212 facing the rotary cover 23 and at the center line. A connection post 205 is provided in the middle of the mounting groove 203 of the cover body 232. The connection post 205 is adapted to the connection hole 204 and is inserted into the connection hole 204, and the connection post 205 is slidably connected to the connection hole 204. In addition, the connection post 205 and the connection hole 204 can play a positioning role, facilitating the quick installation of the rotary cover 23 onto the boss 212.

[0046] In order to prevent the rotary cover 23 from falling off the connection hole 204 of the boss 212, in this embodiment, a fastener 24 is provided on the boss 212. After the fastener 24 penetrates into the connection hole 204 inside the boss 212, it is connected to the connection post 205 to limit and mount the connection post 205 of the rotary cover 23 in the connection hole 204, and the rotary cover 23 can rotate on the boss 212. Specifically, a fixing hole 206 is provided on the connection post 205, and the fixing hole 206 is a threaded hole; the fastener 24 includes a bolt 241 and a gasket 242. The gasket 242 is located inside the boss 212 and abuts against the connection hole 204, and the bolt 241 passes through the gasket 242 and the connection hole 204 in sequence and then is connected to the fixing hole 206 of the connection post 205, thereby limiting and fixing the connection post 205 in the connection hole 204, and thereby rotatably mounting the rotary cover 23 on the boss 212 and the ear hook 21 through the bolt 241 and the gasket 242.

[0047] In this embodiment, a limiting strip 231 is provided at one side edge of the rotary cover 23 facing the ear frame 21, and an annular limiting groove 211 is provided at the end face of the ear frame 21 away from the ear. The limiting strip 231 is snapped into the limiting groove 211. When the rotary cover 23 rotates, the limiting strip 231 will move along the structure of the limiting groove 211, which can play a guiding role to ensure that the rotary cover 23 rotates in a predetermined direction and makes its rotation more stable.

[0048] In this embodiment, an ANC module is provided in the ear body 20. Specifically, an ANC module is provided in the sound generating unit 22. The ANC module is used for active noise reduction of the earphone. Among them, after the rotary cover 23 blocks the ventilation holes 202, the noise reduction effect of the earphone can be improved. In order to ensure the noise reduction quality, the ANC module can be activated for active noise reduction to further improve the noise reduction ability and ensure the sound quality of the earphone.

[0049] Furthermore, a button is provided on the ear body 20, and the ANC module can be started / closed through the button.

[0050] Furthermore, the structures of the two ear bodies 20 are the same and are symmetrically arranged on both sides of the head beam 10, which is not limited thereto.

[0051] When the earphone of this embodiment is in use, wear this earphone on the head and place the two ears in the accommodating cavities 201 of the two ear bodies 20 respectively; when it is necessary to switch the earphone to the open mode, the cover body 232 of the rotary cover 23 can be rotated manually. After rotating in place, the ventilation holes 202 are opened (as Figure 1 shown), so that the earphone is switched to the open mode. At this time, the ventilation holes 202 communicate between the outside and the accommodating cavity 201, allowing the ears to breathe and reducing the stuffy feeling of the user after wearing and using for a long time. When it is necessary to switch the earphone to the closed mode, rotate the rotary cover 23 and make the rotary cover 23 block the ventilation holes 202. At this time, as Figure 2 shown, the ventilation holes 202 are not exposed, which can block wind noise, improve the noise reduction effect and the SNR (signal-to-noise ratio) of the noise environment, and solve the problem of keeping the ears warm in cold weather.

[0052] Embodiment Two:

[0053] Please refer to Figure 9 , compared with Embodiment One, the difference of this embodiment is that this embodiment provides an earphone structure that can make the rotary cover 23 rotate automatically.

[0054] In this embodiment, a driving component is disposed inside the boss 212. The driving component passes through the connection hole 204 and is connected to the connection post 205, so as to drive the rotary cover 23 to rotate through the driving component, and automatically open or close the ventilation hole 202. Specifically, the driving component is set as the motor 25. The output shaft 251 of the motor 25 penetrates into the connection hole 204 and is fixedly connected to the fixing hole 206 on the connection post 205. Therefore, the rotary cover 23 can be driven to rotate by the motor 25, realizing the automatic opening and closing of the ventilation hole 202 without manual operation.

[0055] Further, a button is disposed on the ear body 20. The motor 25 is started through the button, so as to open and close the ventilation hole 202, and further switch the headphone mode.

[0056] Further, the motor 25 is a lifting motor. The lifting motor can drive the rotary cover 23 to rotate and make the rotary cover 23 approach or move away from the boss 212 while rotating; wherein, when the rotary cover 23 approaches the boss 212, the ventilation hole 202 can be gradually closed, and when the rotary cover 23 moves away from the boss 212, the ventilation hole 202 can be gradually opened; specifically, in use, when the rotary cover 23 is rotated by the lifting motor and moves away from the boss 212, the ventilation hole 202 can be opened and the rotary cover 23 can rise on the boss 212; when the lifting motor rotates the rotary cover 23 and finally fits on the boss 212, the rotary cover 23 can just cover the ventilation hole 202.

[0057] Moreover, the connection post 205 at the middle of the rotary cover 23 is installed in the connection hole 204 of the boss 212. Through the limitation of the connection post 205 and the connection hole 204, the up-and-down movement of the rotary cover 23 can be guided, ensuring that the rotary cover 23 accurately moves to a predetermined position along the center line of the boss 212.

[0058] Embodiment Three:

[0059] Please refer to Figure 10 - Figure 13 . Compared with Embodiment One, the difference of this embodiment lies in:

[0060] In this embodiment, a slot 207 is recessed in the side wall of the boss 212; the rotary cover 23 includes an annular plate 234 and a second shielding piece 235. The annular plate 234 is a hollow cylindrical structure. The annular plate 234 is rotatably embedded in the slot 207 of the boss 212, and the second shielding piece 235 is in a fan-shaped structure and is installed on the side wall of the annular plate 234. When the annular plate 234 is rotated or the second shielding piece 235 is pushed, the second shielding piece 235 can be moved to a corresponding position to open or close the ventilation hole 202, thereby switching the headphone mode.

[0061] Further, the boss 212 structure corresponding to the top of the slot 207 is a limiting plate 2121. The limiting plate 2121 extends outward from the boss 212 and covers above the slot 207. The limiting plate 2121 and the boss 212 can be integrally provided or separately provided. When the limiting plate 2121 and the boss 212 are separately provided, the limiting plate 2121 can be installed on the boss 212 by bolts, so as to achieve a detachable setting, and thus facilitate the disassembly and assembly of the rotary cover 23 on the boss 212.

[0062] When the earphone in this embodiment is in use, wear the earphone on the head and make the two ears respectively embedded in the accommodating cavities 201 of the two ear bodies 20. When it is necessary to switch the earphone to the open mode, rotate the circular ring piece 234 of the rotary cover 23 or push the second shielding piece 235, so that the second shielding piece 235 does not overlap with the ventilation holes 202, thereby opening the ventilation holes 202 and switching the earphone to the open mode. At this time, the ventilation holes 202 communicate between the outside and the accommodating cavity 201, allowing the ears to breathe and reducing the stuffy feeling after the user wears and uses it for a long time. When it is necessary to solve the problems of wind noise and heat preservation of the ears in cold weather, rotate the circular ring piece 234 of the rotary cover 23 or push the second shielding piece 235. After rotating in place, the second shielding piece 235 of the rotary cover 23 shields the ventilation holes 202, so as to block the wind noise, improve the noise reduction effect and the SNR (signal-to-noise ratio) of the noise environment, and solve the heat preservation of the ears in cold weather.

[0063] Embodiment 4:

[0064] Please refer to Figure 14 - Figure 16 Compared with Embodiment 1, the difference in this embodiment is that:

[0065] In this embodiment, an annular sliding groove 208 is recessed in the side wall of the boss 212; the rotary cover 23 is of a sector structure and is movably installed in the sliding groove 208. By moving the rotary cover 23 to a corresponding position, the ventilation holes 202 can be opened or closed, so as to switch the earphone mode. Among them, the upper side of the rotary cover 23 is inserted into the sliding groove 208. At the same time, a limiting strip 231 is provided on the lower side of the rotary cover 23, and the limiting strip 231 is stuck in the limiting groove 211 of the boss 212. Therefore, through the cooperation of the limiting groove 211 and the limiting strip 231, the lower side of the rotary cover 23 can be limited, and through the sliding groove 208, the upper side of the rotary cover 23 can be limited. Therefore, corresponding structures are provided for limiting and fixing both the upper and lower sides of the rotary cover 23, so that the rotary cover 23 can be stably installed on the ear body 20 and can rotate stably.

[0066] Certainly, in order to make the installation of the rotary cover 23 more stable, in this embodiment, a clamping groove 209 is recessed on the top surface of the sliding groove 208. The clamping groove 209 is annular and arranged along the structure of the sliding groove 208. A clamping protrusion 236 is protruded on the upper side of the rotary cover 23, and the clamping protrusion 236 is embedded in the clamping groove 209 for limiting, so as to make the installation of the rotary cover 23 more stable.

[0067] Furthermore, in order to facilitate the movement of the rotary cover 23 in the sliding groove 208, in this embodiment, a ball 26 is arranged at the bottom surface of the sliding groove 208. The top surface of the ball 26 contacts the rotary cover 23. By means of the ball 26, the friction force of the rotary cover 23 in the sliding groove 208 can be reduced, facilitating the movement of the rotary cover 23 in the sliding groove 208.

[0068] When the earphone of this embodiment is in use, the earphone is worn on the head, and the two ears are respectively embedded in the accommodating cavities 201 of the two ear bodies 20. When it is necessary to switch to the open mode, the rotary cover 23 is pushed to make the rotary cover 23 rotate and move along the sliding groove 208. After moving in place, the ventilation holes 202 are opened, and the earphone is switched to the open mode. At this time, the ventilation holes 202 communicate between the outside and the accommodating cavity 20, allowing the ears to breathe, and reducing the stuffy feeling of the user after wearing and using for a long time. When it is necessary to switch the earphone to the closed mode, the rotary cover 23 is rotated to make the rotary cover 23 block the ventilation holes 202. At this time, the ventilation holes 202 are closed, so that wind noise can be blocked, the noise reduction effect can be improved, and the SNR (signal-to-noise ratio) of the noise environment can be improved, and the heat preservation of the ears can be solved in cold weather.

[0069] As long as it does not violate the idea of the present invention, any combination of various different embodiments of the present invention should be regarded as the content disclosed by the present invention; within the scope of the technical concept of the present invention, various simple modifications of the technical solutions and any combination of different embodiments that do not violate the idea of the present invention should be within the protection scope of the present invention.
