Technical Field
[0001] This specification relates to the field of electronic device technology, and more particularly to a headphone device. Background Technology
[0002] Among related technologies, open-ear headphones (OWS) have become a popular development direction for new types of headphones because they do not block the ears and are comfortable to wear.
[0003] However, its open structure also has significant drawbacks: due to the inability to form a closed acoustic environment, the headphones have poor immersion and cannot provide users with an immersive listening experience; at the same time, the lack of sound isolation makes the audio content easily interfered with by the external environment, and the audio sound is also easily leaked, resulting in a serious lack of privacy. Summary of the Invention
[0004] In view of the above, one or more embodiments of this specification provide the following technical solutions: According to a first aspect of one or more embodiments of this specification, an earphone device is provided, the earphone device comprising: a first cavity having an integrated sound-generating component inside and a sound mouthpiece on the outside; The wearing component includes an ear support, a second cavity, and an elastic connector. The two ends of the elastic connector are respectively connected to the ear support and the second cavity. The ear is clamped between the first cavity and the second cavity to achieve a fixed wearing effect. An adjustment component is disposed between the first cavity and the ear support, for connecting the first cavity and the ear support, and for adjusting the fit between the mouthpiece and the ear canal.
[0005] Optionally, the ear support is a C-shaped ear support.
[0006] Optionally, the adjustment component includes a rotating shaft disposed on both sides of the first cavity, and a plurality of pairs of fixing grooves are provided on opposite sides of the opening end of the C-shaped ear support. The fixing grooves are linearly arranged along the arc trajectory of the ear support, and the rotating shaft is rotatably and slidably assembled in the fixing grooves.
[0007] Optionally, each pair of fixed grooves corresponds to an adjustment level, and when the rotating shaft moves between different fixed grooves, it realizes the graded adjustment of the distance between the mouthpiece and the ear canal.
[0008] Optionally, the adjustment component further includes a signal triggering device, which generates a corresponding gear indication signal when the rotating shaft is engaged in any pair of fixed grooves.
[0009] Optionally, the second cavity has a built-in battery assembly for providing power to the sound-generating assembly.
[0010] Optionally, the second cavity has an arc-shaped fitting surface on the side facing the auricle.
[0011] Optionally, the first cavity is provided with a handle on the side facing away from the auricle. The handle is an arc-shaped protrusion protruding from the outer shell of the first cavity, which is used for the user to manually hold and apply force to drive the adjustment component.
[0012] In the above embodiments, the angle and distance between the sound mouth on the first cavity and the ear canal can be adjusted by the adjustment component, so that the form of the headphones can be switched between OWS headphones and in-ear headphones to adapt to different scenarios, thereby eliminating the need for users to carry multiple sets of headphones for different scenarios and reducing the user's usage cost and carrying burden.

[0015] Figure 3 This is an exemplary embodiment of a headphone device and its wearing effect. Detailed Implementation
[0016] The user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, data stored, data displayed, etc.) involved in this manual are all information and data authorized by the user or fully authorized by all parties. The collection, use and processing of related data shall comply with the relevant laws, regulations and standards of the relevant countries and regions, and corresponding operation portals shall be provided for users to choose to authorize or refuse.
[0017] In the current headphone market, there are two main types of headphones: open-back (OWS) headphones and in-ear headphones. Each type meets user needs in different scenarios due to its distinct characteristics, but both also have significant technical limitations. On the one hand, OWS headphones offer poor immersion, lack noise isolation, and compromise privacy; on the other hand, in-ear headphones are uncomfortable, interfere with communication and safety, and cannot be worn for extended periods. Therefore, users often need both an OWS headset and a set of in-ear headphones for different situations, which is inconvenient. Switching between two sets of headphones is cumbersome and increases the risk of losing the headphones.
[0018] In view of this, this specification proposes an earphone device that adjusts a first cavity including a sound-producing component and a mouthpiece through an adjustment component in the earphone to adjust the relative position of the mouthpiece and the ear canal, thereby switching the form of the earphone between an OWS earphone and an in-ear earphone.
[0019] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in this specification will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application.
[0020] Please see Figure 1 , Figure 1 This is an exemplary embodiment of a headphone device. For example... Figure 1 As shown, the headphones may include a first cavity 20, a wearing component 10, and an adjustment component 30.
[0021] The first cavity 20 is the core carrier for sound generation, integrating a sound-generating component 21 inside and a sound outlet 22 adapted to the ear canal on the outside. When wearing the headphone device, the audio signal generated by the sound-generating component 21 can be transmitted to the user's ear canal through the sound outlet 22. The outer shell of the first cavity 20 can adopt an arc-shaped design such as spherical or elliptical, and can be made of lightweight materials, such as flexible silicone or ABS.
[0022] The wearing component 10, used to secure the headphone device in the user's ear, may include an ear support 11, a second cavity 12, and an elastic connector 13. The elastic connector 13 is fixedly connected at both ends to the ear support 11 and the second cavity 12, respectively. Its material can be a metal elastic sheet or silicone with built-in memory wire, possessing the ability to recover its deformation and adapt to ear thicknesses while providing stable clamping force. When worn, the first and second cavities clamp the ear to achieve a secure fit; the wearing component 10 adopts an ear-clamping structure.
[0023] The adjustment component 30 is located between the first cavity 20 and the ear support 11. It can be used to connect the first cavity 20 and the ear support 11, and can be used to adjust the fit between the mouthpiece 22 and the user's ear canal when the user wears it. For example, the angle and distance between the mouthpiece 22 and the ear canal can be adjusted by the adjustment component, which can change the fit between the mouthpiece 22 and the ear canal to achieve the switching between OWS headphones and in-ear headphones.
[0024] It should be noted that, in addition to the clip-on structure, the wearing component 10 can also adopt an ear-hook structure. For example, the wearing component can adopt an ear-loop structure to hang the earphone on the auricle.
[0025] In the above embodiments, the angle and distance between the sound mouth on the first cavity and the ear canal can be adjusted by adjusting component 30 to adapt to different ear shapes, fit the ear canal better, and allow the form of the headphones to switch between OWS headphones and in-ear headphones to adapt to different scenarios, so that users no longer need to carry multiple sets of headphones for different scenarios, reducing the user's usage cost and carrying burden.
[0026] In one embodiment, the ear support 11 can be a C-shaped ear support. The arc of the C-shaped ear support precisely matches the human auricle, with its open end facing outwards and its closed end fitting against the area near the tragus, increasing the contact area with the auricle. The C-shaped ear support can be made of flexible silicone with built-in memory wire. The memory wire helps maintain the C-shaped structure, while the flexible silicone improves wearing comfort and has a certain degree of deformation capability to adapt to different ear sizes. The first cavity 20 can be connected to the open end of the C-shaped ear support via the adjustment component 30, allowing it to move and rotate within the enclosed space formed by the C-shaped ear support.
[0027] In one implementation, such as Figure 2 As shown, the adjustment assembly 30 may include rotating shafts 31 disposed on both sides of the first cavity. Several pairs of fixing grooves 32 are formed on opposite sides of the opening end of the C-shaped ear support. The fixing grooves 32 are linearly arranged along the arcuate trajectory of the ear support 11. The surface of the fixing grooves 32 is adapted to the end of the rotating shaft 31 (e.g., a circular groove). The rotating shaft 31 is rotatably mounted within the fixing groove 32, enabling the first cavity 20 to rotate around the rotating shaft 31. The rotation angle range can be set according to actual needs, for example... Meanwhile, the rotating shaft 31 can slide along the arc trajectory of the C-shaped ear support between different pairs of fixed grooves 32 to achieve position switching.
[0028] In one embodiment, the number of fixed grooves 32 can be set according to actual needs, such as 3-5 pairs, arranged equidistantly along the arc trajectory of the C-shaped ear support 11. Each pair of fixed grooves corresponds to an adjustment level, set according to the fit between the first cavity and the ear canal after adjustment. For example, with 3 pairs of fixed grooves 32, from closest to the ear canal to furthest from the ear canal, they are respectively "tight," "medium," and "open." By driving the rotating shaft 31 to slide from the current fixed groove into the adjacent groove, the distance between the mouthpiece and the ear canal can be adjusted in stages. For example, when the rotating shaft 31 is engaged in the "tight" position, the distance between the mouthpiece and the ear canal is closest, and the fit is tightest, forming an in-ear state; when engaged in the "open" position, the distance between the mouthpiece and the ear canal is farthest, and the fit is worst, forming an OWS state.
[0029] In one embodiment, in order to prevent the rotating shaft 31 from sliding on its own without external force, an interference fit can be used between the rotating shaft 31 and the inner wall of the fixing groove 32, or a damping element, such as an elastic pad or friction plate, can be provided in the adjustment assembly to ensure that the rotating shaft is stably locked in a pair of fixing grooves without external force.
[0030] In one embodiment, the adjustment component 30 may further include a signal triggering device. When the rotating shaft 31 is engaged in any pair of fixed grooves 32, the signal triggering device may generate a prompt signal corresponding to the gear position. The prompt signal may be a voice signal or a vibration signal. For example, "tight gear" corresponds to 1 vibration, "medium gear" corresponds to 2 vibrations, and "open gear" corresponds to 3 vibrations.
[0031] In one embodiment, the second cavity 12 may contain a built-in battery assembly 14, which may be a rechargeable lithium battery. The battery assembly 14 is electrically connected to the sound-generating component 21 and the signal triggering device in the first cavity 20 through a wiring channel hidden in the elastic connector 13, the C-shaped ear support 11 and the first cavity 20, so as to provide working power.
[0032] In one embodiment, the outer shell of the second cavity 12 can be an arc-shaped block structure adapted to the auricle, with an arc-shaped fitting surface facing the auricle, so that when clamped with the first cavity 20, it fits the circular surface of the first cavity 20. Its surface material can be a lightweight material, such as flexible silicone or ABS material.
[0033] In one embodiment, the first cavity 20 has a handle 23 on the side facing away from the auricle. The handle is an arc-shaped protrusion protruding from the outer shell of the first cavity 20, used by the user to manually grip and apply force to drive the adjustment component, for example, by prying the handle with the fingertips. The surface of the handle 23 may have an anti-slip texture, and the material is the same as the outer shell of the first cavity, which can be manufactured by a one-piece molding process to ensure structural strength. The position of the handle 23 corresponds to the middle area of the first cavity 20 and corresponds to the position of the pivot of the adjustment component 30. When the user grips the handle and applies force, he can directly drive the pivot of the first cavity 20 or slide it between the pairs of fixing grooves 32 to adjust the fit between the mouthpiece 22 and the ear canal.
[0034] In one embodiment, the adjustment component 30 may include an electronically controlled device that automatically drives the rotating shaft 31 to rotate and slide, eliminating the need for manual operation of the latch by the user. Automatic drive of the rotating shaft can be performed based on adjustment commands input by the user.
[0035] The user can input adjustment commands in various ways, such as through a terminal application APP connected to the headphones; or through voice commands sent by the user; or through touch operations on the headphones, etc. There are no specific limitations here.
[0036] Please see Figure 3 , Figure 3 This is an exemplary embodiment illustrating the wearing effect of a headphone device. For example... Figure 3As shown, when the user wears the headphone device, the C-shaped ear support 11 fits snugly against the inner part of the auricle near the tragus, completely conforming to the inner contour of the auricle. The first cavity 20 is located within the enclosed space formed by the C-shaped ear support 11, with the mouthpiece 22 facing the ear canal. A handle is provided on the side of the first cavity 20 facing away from the auricle. The side of the second cavity 12 facing the auricle (arc-shaped fitting surface) precisely fits against the rear contour of the auricle, forming a stable opposing clamping force with the first cavity through the elastic connector 13, clamping the auricle to achieve a secure fit. The user can manually turn the handle 23 to drive the rotation of the adjustment component 30 or slide it between the fixed grooves to adjust the fit between the mouthpiece 22 and the ear canal, thereby switching between OWS headphones and in-ear headphones.
