Description

Technical Field

[0001] This utility model relates to the field of headphone technology, and in particular to a headphone compartment with a hovering positioning cover. Background Technology

[0002] True wireless stereo (TWS) earbuds, as a type of portable audio device, have become widely used in daily life. Their accompanying charging case not only stores and charges the earbuds, but its opening and closing mechanism is also closely related to the user experience.

[0003] Currently, most earphone charging cases on the market use a magnetic hinge structure to open and close the top and bottom covers. This traditional design means the opening angle is singular and fixed, typically set to an angle greater than 90°. While this single-angle opening method meets basic opening and closing needs, it lacks flexibility in actual use. Users cannot adjust the opening angle according to usage scenarios or personal habits, leading to inconvenience in certain environments, such as confined spaces or one-handed operation. Furthermore, the fixed opening angle limits the naturalness and convenience of taking out and placing earphones, impacting the user experience. Although some adjustable-angle cover structures exist in existing technologies, they mostly rely on complex mechanical components or damping structures, resulting in high costs, easy wear, and inaccurate positioning, making widespread application in miniaturized and lightweight earphone charging cases difficult. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide an earphone compartment with a hovering positioning cover, which solves the technical problems of the charging case having a single fixed opening angle, making it difficult to flexibly adapt to different usage scenarios, as well as the existing adjustable angle structures being complex, costly, and difficult to apply in miniaturized products.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: This utility model discloses an earphone compartment with a hovering positioning cover, comprising: Warehouse body; The cover is rotatably connected to one side of the compartment body; A hovering positioning magnetic assembly is disposed at the rotatable connection between the cover and the chamber. The hovering positioning magnetic assembly includes a moving magnetic block and a fixed magnetic array. The moving magnetic block is mounted on the cover and rotates with the cover. The fixed magnetic array is embedded in the chamber in an arc shape. The moving magnetic block is disposed on the concave side of the fixed magnetic array and can move within a fan-shaped area defined by the arc radius of the fixed magnetic array. The hovering positioning magnetic assembly has a coupled positioning adjustable state and a decoupled state. When the coupling positioning is adjustable, the moving magnetic block is located within the fan-shaped area defined by the arc radius of the fixed magnetic array and is magnetically coupled to the fixed magnetic array; In the decoupled state, the moving magnetic block moves outside the sector area, releasing the magnetic coupling with the fixed magnetic array.

[0006] As a preferred embodiment, an earphone housing frame is fixedly installed inside the housing, and an inner cover corresponding to the earphone housing frame is embedded in the cover. A connecting ear block protrudes from one side of the cover, and the connecting ear block is rotatably mounted on the earphone housing frame via a pivot. A first groove is formed on the side of the connecting ear block away from the cover, and a second groove corresponding to the first groove is formed on the earphone housing frame. The moving magnet is embedded in the first groove, and the fixed magnet array is arranged in the second groove.

[0007] As a preferred embodiment, a first closing magnet is installed on the side of the earphone housing frame away from the pivot, the first closing magnet is disposed at both symmetrical ends of the earphone housing frame, and a second closing magnet for magnetic coupling with the first closing magnet is installed on the inner cover of the housing.

[0008] As a preferred embodiment, the fixed magnetic array includes a plurality of fixed magnetic blocks, which are disposed on the second groove and arranged in an arc shape.

[0009] As a preferred embodiment, the number of fixed magnetic blocks is 3.

[0010] As a preferred embodiment, multiple fixed magnetic blocks together form a 1 / 4 half-arc array.

[0011] As a preferred embodiment, the first groove is formed in the middle of the connecting ear block near the earphone housing frame, the pivot is passed through the connecting ear block and located between the first groove and the cover, and the housing is also provided with an avoidance notch corresponding to the connecting ear block.

[0012] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly improves the flexibility and ease of use of the opening angle adjustment by using the moving magnetic block in the hovering positioning magnetic group and the fixed magnetic array embedded in an arc shape, realizing the multi-angle hovering function, while reducing the complexity of the structure and the risk of wear, and solving the technical problems of the single fixed opening angle of the traditional charging box and the complexity and high cost of the existing adjustable angle structure.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0017] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0018] Please see Figures 1 to 5This utility model provides an earphone case with a hovering positioning cover, including a case body 10, a cover 20, and a hovering positioning magnetic assembly 30. The case body 10 serves as the main supporting structure, providing space for the internal earphones. The cover 20 is used to seal and protect the internal earphones, preventing dust from entering and accidental falling. The hovering positioning magnetic assembly 30 is a key component for the core function, solving the problem of the single rotation angle of traditional magnetic attraction. Specifically, the cover 20 is rotatably connected to one side of the case body 10, forming a basic opening and closing structure to meet basic usage requirements. The hovering positioning magnetic assembly 30 is located at the rotatable connection between the cover 20 and the case body 10, achieving a compact layout and adapting to the design requirements of miniaturization and lightweight earphone cases. The hovering positioning magnetic assembly 30 includes a moving magnetic block 31 and a fixed magnetic array 32. The moving magnetic block 31 serves as a follower magnetic force source, and its magnetic field direction and position change with the movement of the cover 20. The fixed magnetic array 32 serves as a fixed multi-position magnetic force reference, and its specific magnetic pole arrangement defines multiple hovering positions. The moving magnetic block 31 is mounted on the cover 20 and rotates with the cover 20, ensuring that the magnetic interaction and opening / closing action are synchronized. The fixed magnetic array 32 is embedded in the compartment 10 in an arc shape, and its arc trajectory precisely matches the rotation path of the cover 20. The moving magnetic block 31 is located on the concave side of the fixed magnetic array 32, forming a stable magnetic interaction relationship, enhancing positioning reliability. The moving magnetic block 31 can move within the fan-shaped area defined by the arc radius of the fixed magnetic array 32, which is the effective multi-angle hovering working range. The hovering positioning magnetic assembly 30 has a coupled positioning adjustable state and a decoupled state. In the coupled positioning adjustable state, the moving magnetic block 31 is located within the fan-shaped area defined by the arc radius of the fixed magnetic array 32. At this time, it is in a precise magnetic control area and is magnetically coupled with the fixed magnetic array 32. The attraction and repulsion between the magnetic poles generate a balanced torque, thereby achieving stepless hovering of the cover 20. In this state, the user can freely adjust and stabilize the opening angle according to the usage scenario. In the decoupled state, the moving magnetic block 31 moves outside the fan-shaped area, that is, it leaves the preset hovering control range and releases the magnetic coupling with the fixed magnetic array 32. The cover 20 is no longer constrained by the hovering magnetic group and can smoothly complete the final opening and closing action. That is, the decoupled state is used to realize the complete closure of the cover 20 or the maximum angle opening.

[0019] Through the magnetic coupling between the moving magnetic block 31 and the arc-shaped fixed magnetic array 32, the angle adjustability and positioning accuracy during the opening process are improved, achieving multi-angle adaptive hovering from slightly open to fully open. At the same time, by replacing the traditional mechanical damping structure with a pure magnetic positioning method, the complexity of the mechanism, the wear of parts, and the production cost are significantly reduced. This effectively solves the inconvenience caused by the single fixed opening angle of traditional charging boxes, as well as the technical problem that existing adjustable angle solutions are difficult to widely apply in miniaturized products due to their complex structure.

[0020] In this embodiment, an earphone housing frame 11 is fixedly installed inside the housing 10 to stably support the earphones and ensure the charging contacts are aligned. An inner cover 21 corresponding to the earphone housing frame 11 is embedded in the cover 20. When the cover is closed, it forms a sealed storage space together with the earphone housing frame 11. A connecting ear block 22 protrudes from one side of the cover 20. The connecting ear block 22 is rotatably mounted on the earphone housing frame 11 via a pivot 40, forming the basic physical rotation center. A first groove 221 is provided on the side of the connecting ear block 22 away from the cover 20 to provide a precise installation position for the moving magnetic block 31. A second groove 111 corresponding to the first groove 221 is provided on the earphone housing frame 11 to accommodate the fixed magnetic array 32 and together with the first groove 221, forms a magnetic working cavity. The moving magnetic block 31 is embedded in the first groove 221 to ensure that it rotates synchronously with the connecting ear block 22. The fixed magnetic array 32 is arranged in the second groove 111. Its fixed installation method ensures the stability of the magnetic reference.

[0021] Furthermore, a first closing magnet (not shown in the figure) is installed on the side of the earphone housing frame 11 away from the pivot 40. As the main magnetic force source in the closed state, the first closing magnet (not shown in the figure) is set at both ends of the earphone housing frame 11. The symmetrical layout ensures that the force is even when the cover is closed, avoiding gaps on one side. A second closing magnet (not shown in the figure) is installed on the inner cover 21 for magnetic coupling with the first closing magnet (not shown in the figure). It cooperates with the first closing magnet (not shown in the figure) to provide a clear closing feel and holding force.

[0022] The fixed magnetic array 32 includes multiple fixed magnetic blocks 321. Multiple precise hovering positions are defined by discrete magnetic pole arrangement. The multiple fixed magnetic blocks 321 are set on the second groove 111 and arranged in an arc shape. Their arrangement trajectory precisely corresponds to the rotation path of the moving magnetic block 31.

[0023] In the preferred embodiment, the number of fixed magnetic blocks 321 is 3, which achieves the best balance between manufacturing cost and hovering point density.

[0024] Multiple fixed magnetic blocks 321 together form a 1 / 4 half-arc array, which is an effective hovering range of about 90 degrees, covering the most commonly used opening angles.

[0025] Furthermore, the first groove 221 is formed in the middle of the connecting ear block 22 near the earphone housing frame 11, so that the magnetic force application point is close to the rotating shaft 40 to obtain a better torque effect. The rotating shaft 40 passes through the connecting ear block 22 and is located between the first groove 221 and the cover 20. This arrangement allows the rotating shaft 40 to simultaneously perform the dual functions of physical support and magnetic positioning. The housing 10 also has a clearance notch 12 corresponding to the connecting ear block 22 to provide the necessary movement space for the connecting ear block 22 during rotation and prevent structural interference.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the principles of the present utility model should be included within the protection scope of the present utility model.
