Description

Technical Field

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

[0002] Headphones are used to receive signals from media players or receivers and convert those signals into sound waves using speakers placed close to the ears, allowing users to enjoy listening to audio independently. As the headphone industry develops, users' demands for a superior headphone experience continue to rise.

[0003] However, in related technologies, headphone designs often fail to balance the ability to isolate external noise and the ability to hear external sounds. In other words, when users use headphones, the headphones cannot improve their ability to isolate external noise or improve the user's ability to hear external sounds for different usage scenarios, making it impossible for headphones to perform well in different usage scenarios. Summary of the Invention

[0004] This application aims to provide an earphone that at least solves the technical problem that earphones cannot adequately cater to different usage scenarios.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] This application provides an earphone, which includes a first body, a first speaker, and a second body. The first body has a through hole extending along a first direction. The first speaker is disposed on one side of the first body in the first direction. The second body is disposed on the side of the first body opposite to the first speaker in the first direction. The second body is movably disposed relative to the first body between a first position and a second position. In the first position, the projection of the second body in the first direction is misaligned with the projection of the through hole in the first direction. In the second position, the projection of the second body in the first direction and the projection of the through hole in the first direction at least partially overlap.

[0007] The headphones provided in this application include a first main body, a first speaker, and a second main body. The first speaker is disposed on one side of the first main body in a first direction and is used to play sound to the user. The second main body is disposed on the side of the first main body opposite to the first speaker in the first direction. By movably distributing the second main body relative to the first main body between a first position and a second position, and by providing a through hole in the first main body along the first direction, when the second main body is in the first position (i.e., when the projection of the second main body in the first direction and the projection of the through hole in the first direction are misaligned), the second main body does not block the through hole, allowing the user to obtain sound from the external environment through the through hole, thereby improving the user's ability to communicate with the external environment. When the second main body is in the second position (i.e., when the projection of the second main body in the first direction and the projection of the through hole in the first direction at least partially overlap), the second main body can block at least part of the sound from the external environment, making it difficult for noise from the external environment to be received by the user through the through hole, thus improving the headphones' ability to isolate external noise and allowing the user to better listen to the sound played by the first speaker in the headphones. Therefore, by simply adjusting the position of the second main body relative to the first main body, the headphones can have different noise isolation performance for different usage scenarios, thus enabling the headphones to have good performance in different usage scenarios.

[0029] Headphones are used to receive signals from media players or receivers and convert these signals into sound waves using speakers placed close to the ears, allowing users to listen to audio more effectively. As the headphone industry has developed, user demands for the headphone experience have continuously increased. However, in related technologies, headphone designs often fail to balance the ability to isolate external noise with the ability to hear ambient sounds. In other words, headphones cannot improve their noise isolation or enhance the user's ability to hear ambient sounds for different usage scenarios, resulting in inconsistent performance across various situations.

[0030] For example, in related technologies, some headphones have good noise isolation capabilities. These headphones can isolate relatively noisy external environments and provide users with clearer sound, thereby improving the user experience. However, when users need to listen to external sounds, these headphones will hinder their connection with the outside world. As another example, in related technologies, some headphones have good sound transmission capabilities. These headphones help users listen to external sounds, facilitating communication with the outside world. However, when users need to listen to the audio within the headphones clearly, ambient noise will reduce the user's ability to receive the audio from the headphones.

[0031] To address the aforementioned technical problems, this application is provided. To better understand this application, the headphones according to embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0032] Figure 1 This is a schematic diagram of the structure of the earphone 10 according to some embodiments of this application. Figure 2 The diagram shows the structure of the earphone 10 in some other embodiments of this application. In the diagram, the X direction is the first direction, the Y direction is the second direction, and the Z direction is the third direction. The first direction X, the second direction Y, and the third direction Z intersect each other.

[0033] like Figure 1 and Figure 2 As shown, this application embodiment provides an earphone 10, which includes a first body 1, a first speaker 3, and a second body 2. The first body 1 is provided with a through hole 1a extending along a first direction X. The first speaker 3 is disposed on one side of the first body 1 in the first direction X. The second body 2 is disposed on the side of the first body 1 opposite to the first speaker 3 in the first direction X. The second body 2 is movably disposed relative to the first body 1 between a first position and a second position. In the first position, the projection of the second body 2 in the first direction X is misaligned with the projection of the through hole 1a in the first direction X. In the second position, the projection of the second body 2 in the first direction X and the projection of the through hole 1a in the first direction X at least partially overlap.

[0034] The earphone 10 provided in this application includes a first body 1, a first speaker 3, and a second body 2. The first speaker 3 is disposed on one side of the first body 1 in a first direction X, and the first speaker 3 is used to play sound to the user. The second body 2 is disposed on the side of the first body 1 facing away from the first speaker 3 in the first direction X. By movably displacing the second body 2 relative to the first body 1 between a first position and a second position, and by providing a through hole 1a extending along the first direction X on the first body 1, the second body 2, when in the first position, such as... Figure 1As shown, when the projection of the second body 2 in the first direction X is misaligned with the projection of the through hole 1a in the first direction X, the second body 2 does not block the through hole 1a, allowing the user to obtain sound from the external environment through the through hole 1a, thereby improving the user's ability to communicate with the external environment. However, when the second body 2 is in the second position, as... Figure 2 As shown, when the projection of the second body 2 in the first direction X at least partially overlaps with the projection of the through hole 1a in the first direction X, the second body 2 can block at least part of the sound from the external environment, making it difficult for noise from the external environment to be received by the user through the through hole 1a. This improves the noise isolation capability of the headphones 10, allowing the user to better listen to the sound played by the first speaker 3 in the headphones 10. Therefore, by simply adjusting the position of the second body 2 relative to the first body 1, the headphones 10 can have different sound insulation performance for different usage scenarios, thus enabling the headphones 10 to have good performance in different usage scenarios.

[0035] In some embodiments, the first body 1 includes a support portion 11 and a main body portion 12 arranged side by side and connected to each other in the second direction Y, and a through hole 1a is provided in the main body portion 12. In a first position, such as... Figure 1 As shown, the projection of the second body 2 in the first direction X overlaps with at least a portion of the projection of the support portion 11 in the first direction X, at the second position, as... Figure 2 As shown, the projection of the second body 2 in the first direction X overlaps with at least a portion of the projection of the body portion 12 in the first direction X.

[0036] When a user wears the earphone 10, both the main body 12 and the support 11 can abut against the auricle to limit the movement of the earphone 10 relative to the user's ear and improve the reliability of wearing the earphone 10. The main body 12 can be located on the side of the user's ear canal closer to the auricle, so that when the second main body 2 is in the first position, ambient sounds can be better received by the user through the through-hole 1a and the user's ear canal, and when the second main body 2 is in the second position, it can better block ambient noise from being received by the user through the through-hole 1a and the user's ear canal.

[0037] Optionally, when the second body 2 is in the first position, the projection of the second body 2 in the first direction X may be located within the projection of the support portion 11 in the first direction X, thereby improving the structural stability of the earphone 10. Optionally, when the second body 2 is in the second position, the projection of the second body 2 in the first direction X may be located within the projection of the main body portion 12 in the first direction X, thereby improving the structural stability of the earphone 10.

[0038] Optionally, when the second main body 2 is in the first position, the support portion 11 in the first direction X can provide a certain supporting force to the second main body 2 to improve the structural stability of the earphone 10. Optionally, when the second main body 2 is in the second position, the main body portion 12 in the first direction X can provide a certain supporting force to the second main body 2 to improve the structural stability of the earphone 10.

[0039] like Figure 1 and Figure 2 As shown, in some embodiments, the earphone 10 further includes a first elastic portion 111 disposed on the support portion 11 on the side away from the main body portion 12 in the second direction Y, and the first elastic portion 111 protrudes from the support portion 11. By providing the first elastic portion 111 on the side of the support portion 11 away from the main body portion 12 in the second direction Y, the earphone 10 can restrict the movement of the earphone 10 relative to the ear through the contact between the first elastic portion 111 and the auricle and the contact between the first main body portion 1 and the auricle, thereby improving the reliability of the earphone 10 when worn.

[0040] The material of the first elastic part 111 can be various. The material of the first elastic part 111 can be an elastic material. When the earphone 10 is worn by users with different ear sizes, the first elastic part 111 can adapt to the different ear sizes through deformation. That is, the first elastic part 111 can better fit against different ear sizes, thereby improving the reliability of the earphone 10 when worn. Optionally, the material of the first elastic part 111 may include silicone.

[0041] Optionally, the first elastic part 111 may be in the shape of an arc, with both ends of the first elastic part 111 connected to the support part 11, and the portion between the two ends of the first elastic part 111 may be spaced apart from the support part 11, so that the first elastic part 111 has sufficient deformable space, so that the earphone 10 can be worn by users with different ear sizes.

[0042] There are several ways to arrange the first speaker 3 on the first main body 1. Optionally, the first speaker 3 can be disposed on the main body 12 so that the sound played by the headphones 10 can be received by the user's ear through the ear canal. Optionally, the sound outlet of the first speaker 3 can be disposed around at least part of the through hole 1a to improve the structural compactness of the first main body 1, so that the first speaker 3 can have a better placement area, and also facilitate the sound effect played by the first speaker 3 to be received by the user through the ear canal.

[0043] Figure 3 This is a schematic diagram of the structure of the second body 2 in some embodiments of this application.

[0044] like Figure 3As shown, in some embodiments, the headphones 10 further include a second speaker 4 disposed on the side of the second body 2 facing the first body 1 in the first direction X. In the second position, at least a portion of the projection of the second speaker 4 in the first direction X overlaps with the projection of the through hole 1a in the first direction X. By providing a second speaker 4 that can also be used to play sound, when the second body 2 is in the second position, the sound played by the second speaker 4 can be better transmitted to the user's ears through the through hole 1a, allowing the user to listen to the sound played by the first speaker 3 and the second speaker 4 simultaneously, thereby improving the user experience.

[0045] Optionally, the first speaker 3 and the second speaker 4 may play the same audio signal to increase the overall volume of the audio played by the headphones 10, allowing the user to receive the audio more clearly. Optionally, the first speaker 3 and the second speaker 4 may also play different audio signals, enabling the headphones 10 to play audio with surround or stereo effects. That is, the audio played by the headphones 10 may consist of several sub-sound segments, wherein the first speaker 3 and the second speaker 4 can be used to play different sub-sound segments.

[0046] Please continue to refer to Figure 3 In some embodiments, the earphone 10 further includes a second elastic portion 21. In the first direction X, the second elastic portion 21 is connected to the side of the second body 2 facing the first body 1. In the second position, the second elastic portion 21 abuts against the surface of the first body 1 facing the second body 2.

[0047] The material of the second elastic part 21 can be varied. The material of the second elastic part 21 can be an elastic material, allowing it to have a good fit with the surface of the first body 1. This ensures that when the second body 2 is in the second position, the second body 2 and the second elastic part 21 can effectively isolate external environmental noise, and also allows the sound played by the second speaker 4 to be transmitted to the user's ears more efficiently. Optionally, the material of the second elastic part 21 may include silicone.

[0048] In some embodiments, in the second position, the second elastic portion 21 is disposed around at least part of the through hole 1a to further improve the isolation effect of the earphone 10 against external ambient noise when the second body 2 is in the second position.

[0049] In some embodiments, the headphones 10 further include a control module (not shown), which controls the second speaker 4 to turn off when the second body 2 is in the first position; and / or, controls the second speaker 4 to turn on when the second body 2 is in the second position. By controlling the second speaker 4 to only turn on in the second position, the working efficiency of the second speaker 4 is improved, making it less likely for the second speaker 4 to play sound that would affect the user's reception of external sounds when the user needs to listen to sounds from the outside environment, and also reducing the energy efficiency of the headphones 10.

[0050] Optionally, the control module is used to control the second speaker 4 to turn on when the second body 2 is in the second position and the first speaker 3 is turned on.

[0051] In some optional embodiments, the first position can be any position of the second body 2 when the projection of the second body 2 in the first direction X is misaligned with the projection of the through hole 1a in the first direction X. At this time, the second body 2 does not cover the end of the through hole 1a facing the second body 2 in the first direction X, so that the user's ear can receive the sound of the external environment better through the through hole 1a.

[0052] Optionally, the second position can be the position of the second body 2 when the projection of the through hole 1a in the first direction X is located within the projection of the second body 2 in the first direction X. At this time, the second body 2 covers the end of the through hole 1a facing the second body 2 in the first direction X, so that at least part of the noise in the external environment can be blocked and isolated by the second body 2, making it difficult for the noise in the external environment to be transmitted to the user's ears through the through hole 1a, thereby reducing the interference of the noise in the external environment on the user's listening to the sound played by the first speaker 3.

[0053] Users can adjust the position of the second main body 2 relative to the first main body 1 to regulate the noise isolation performance of the headphones 10 for different usage scenarios. For example, when a user needs to communicate with external sounds, the second main body 2 can be adjusted to the first position to reduce its isolation from the external environment, thus improving the user's ability to receive external sounds. Conversely, when a user needs to listen to the audio played by the headphones 10 with peace of mind, the second main body 2 can be adjusted to the second position to increase its isolation from the external environment, allowing the user to listen to the audio played by the headphones 10 with greater peace of mind.

[0054] This application does not limit the driving method for the relative movement between the first body 1 and the second body 2. In some optional embodiments, the user can manually adjust the position of the second body 2 relative to the first body 1, that is, the user can manually adjust the movement of the second body 2 between the first position and the second position. In other optional embodiments, the movement of the second body 2 between the first position and the second position can also be driven and adjusted by setting a corresponding driving mechanism (not shown in the figure). Optionally, the control module can also be connected to the driving mechanism to control the movement of the second body 2 between the first position and the second position.

[0055] There are various methods for movably configuring the second body 2 relative to the first body 1. In some embodiments, the second body 2 is movable relative to the first body 1 along a second direction Y between a first position and a second position.

[0056] In this embodiment, optionally, one of the first body 1 and the second body 2 may be provided with a sliding groove structure (not shown in the figure), and the other may be provided with a slider structure (not shown in the figure), so that the second body 2 can move relative to the first body 1 along the second direction Y between a first position and a second position through the slidable connection between the sliding groove structure and the slider structure. There are various slidable connection structures for the sliding groove structure and the slider structure, which will not be elaborated upon in this article.

[0057] Figure 4 This is a schematic diagram of the structure of the first body 1 in some embodiments of this application. Figure 5 This is a cross-sectional view of the rotating component 5 along the first direction X in some embodiments of this application.

[0058] like Figures 3 to 5 As shown, in some other embodiments, the earphone 10 further includes a rotating assembly 5, wherein the second body 2 is rotatably disposed relative to the first body 1 about an axis extending along a first direction X between a first position and a second position via the rotating assembly 5. For ease of description, the following embodiments are illustrated using the example of the second body 2 being rotatably disposed relative to the first body 1 via the rotating assembly 5.

[0059] like Figures 3 to 5As shown, in some embodiments, the rotating assembly 5 includes a rotating shaft 51 and a rotating hole 52 rotatably connected to each other. A first limiting part 521 with a protrusion is provided on the inner surface of the rotating hole 52, and a first stop part 511 and a second stop part 512 with a protrusion are provided on the circumferential surface of the rotating shaft 51. The rotating shaft 51 is disposed in one of the first body 1 and the second body 2, and the rotating hole 52 is disposed in the other. The first limiting part 521 is rotatably disposed around the rotating shaft 51 between the first stop part 511 and the second stop part 512. In a first position, the first limiting part 521 abuts against the first stop part 511, and in a second position, the first limiting part 521 abuts against the second stop part 512. By providing a first limiting part 521 on the inner surface of the rotating hole 52, and providing a first stop part 511 and a second stop part 512 on the circumferential surface of the rotating shaft 51, the first limiting part 521 can only rotate around the rotating shaft 51 between the first stop part 511 and the second stop part 512, thereby limiting the angle of rotation of the second body 2 relative to the first body 1, so as to facilitate the user's adjustment of the position of the second body 2.

[0060] In some optional embodiments, the rotating shaft 51 is disposed on the first body 1. Optionally, the rotating shaft 51 may be disposed at the junction of the support portion 11 and the main body portion 12. The rotating hole 52 may be disposed on one side of the second body 2 in the second direction Y.

[0061] Optionally, the first stop portion 511 and the second stop portion 512 can be respectively disposed on both sides of the rotating shaft 51 in the second direction Y. Optionally, the included angle between the surface of the first stop portion 511 facing the first limiting portion 521 and the surface of the second stop portion 512 facing the first limiting portion 521 is 180°, so that when the first limiting portion 521 abuts against the first stop portion 511, the orthographic projection of the second main body 2 in the first direction X can overlap well with the orthographic projection of the support portion 11 in the first direction X, and when the first limiting portion 521 abuts against the second stop portion 512, the orthographic projection of the second main body 2 in the first direction X can overlap well with the orthographic projection of the main body portion 12 in the first direction X.

[0062] This application does not limit the extension dimensions of the first stop portion 511 and the second stop portion 512 in the first direction X. Optionally, the extension dimensions of the first stop portion 511 and the second stop portion 512 in the first direction X are smaller than the extension dimensions of the rotating shaft 51 in the first direction X.

[0063] Figure 6 This is a partial cross-sectional view of the rotating component 5 along the third direction Z in some embodiments of this application.

[0064] like Figure 6As shown, optionally, the first stop portion 511 and the second stop portion 512 are spaced apart from the first body 1 in the first direction X. The wall portion is also provided with a second limiting portion 522 at one end facing the first body 1 in the first direction X. The second limiting portion 522 protrudes towards the rotating hole 52 and surrounds at least part of the rotating hole 52. The second limiting portion 522 is located between the first stop portion 511 and the second stop portion 512 and the first body 1, and the surface of the second limiting portion 522 facing away from the first body 1 abuts against the first stop portion 511 to limit the movement of the second body 2 relative to the first body 1 in the first direction X, thereby improving the structural stability of the earphone 10.

[0065] In these optional embodiments, the rotating shaft 51 has a first top surface 51b at the end opposite to the first body 1 in the first direction X. The first top surface 51b and the surface of the first stop portion 511 facing the first body 1 have a first gap. The rotating hole 52 has a second top surface 52a at the side opposite to the second limiting portion 522 in the first direction X. The second top surface 52a and the surface of the second limiting portion 522 opposite to the first body 1 have a second gap. The first gap can be equal to the second gap, so that the first top surface 51b can abut against the second top surface 52a to further restrict the movement of the second body 2 relative to the first body 1 in the first direction X, thereby improving the structural stability of the earphone 10.

[0066] The above description is merely a specific implementation of this application. Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the systems, modules, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here. It should be understood that the protection scope of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the protection scope of this application.
