Description

[Technical Field]

[0002] This utility model relates to the technical field of personal small audio playback devices, and more particularly to the technical field of headphones. [Background Technology]

[0004] Headphones are a common personal electronic product. With technological advancements and development, headphones have evolved from wired to wireless, from active to passive, and from RF pairing to Bluetooth pairing, resulting in a wide variety of types to suit the diverse purposes and needs of consumers.

[0005] Over-ear headphones, as a type of personal wearable headphone that is relatively large, complex in structure, and has a more high-end and realistic sound effect, have always been favored by music enthusiasts and e-sports athletes, offering a more immersive atmosphere and a highly realistic 3D stereo sound reproduction effect.

[0006] Over-ear headphones, being relatively large and complex in structure with many components, have long been criticized for their weight and portability. The structure of over-ear headphones generally consists of two earpieces on both sides corresponding to the human ear, which contain the sound-producing components. The earpieces at both ends are connected by an arc-shaped headband, which is worn on the top of the head to support the weight of the headphones and keep them on the head.

[0007] To accommodate different head circumferences and the distance from the top of the head to the ears, most headphones have retractable and adjustable headbands, and the earcups can extend and retract vertically and swing back and forth horizontally. However, due to structural limitations, they cannot achieve omnidirectional rotation. For example, patent CN202411343302.9, which discloses a rotating structure and headphones, describes a method where a rotation limiting structure is placed on the sliding arm of the headphones. This makes the rotating structure easy to assemble and provides good strength. Furthermore, this design allows for a greater range of rotation for the earcups, and the structure allows for rotation in only one direction rather than multiple arbitrary degrees of freedom. [Summary of the Invention]

[0009] This invention addresses the above-mentioned problems by proposing a high-degree-of-freedom omnidirectional adjustable headphone with an adjustable structure between the headband and the earcup. This structure allows the earcup to swing freely 360° relative to the earband, resulting in better free adjustment, adapting to a wider range of adjustment needs, and providing greater comfort and a better user experience.

[0010] This utility model relates to an ear-shell adjustable over-ear headphone, wherein the over-ear headphone includes a headband, an ear-shell connector, and an ear shell, wherein an ear-shell connector is connected to each end of the headband, and the ear shell is installed through the ear-shell connector. The ear shell includes an ear shell body and electronic components disposed within the ear shell body. The ear shell connector includes an outer fixing cover, an inner fixing cover, an adjusting silicone pad, and a locking screw. The inner fixing cover has an adjusting protrusion on the side facing the ear shell. The inner fixing cover is locked and fixed by the locking screw disposed within the ear shell body with its adjusting protrusion pressing against the adjusting silicone pad. The outer fixing cover is attached to the outside of the inner fixing cover.

[0011] The cross-sectional structure of the adjusting silicone pad is an "L" stepped shape. The adjusting silicone pad adapts its stepped surface to the adjusting protruding edge of the inner fixing cover, and the two are fitted together.

[0012] There is also a screw-locking silicone pad between the screw inside the ear shell and the ear shell body.

[0013] The inner and outer fixing covers are installed together via a movable structure.

[0014] The movable structure includes screw locking or snap fasteners.

[0015] The headband includes a headband portion at the top and insert portions at both ends of the headband portion for assembly with earpiece connectors.

[0016] The headband insert is fitted into the outer fixing cover of the ear shell connector.

[0017] The upper side of the outer fixing cover has a card slot, into which the insert portion of the headband is inserted and secured by screws.

[0018] A decorative piece is also provided on the outer side of the outer fixing cover of the ear shell connector.

[0019] The ear-shell adjustable headphones of this utility model adopt an adjustable silicone pad and an adjustable convex edge design in the ear shell part, which achieves a high degree of freedom of omnidirectional adjustment. An adjustment structure is set between the headband and the ear shell, allowing the ear shell to swing freely in a conical angle within a range of 360° relative to the earband, thereby obtaining a better free adjustment effect, adapting to a wider range of adjustment needs, and providing better comfort and user experience during wearing.
