Description

Technical Field

[0001] This utility model belongs to the field of headphone technology, and particularly relates to a multi-joint adjustable and retractable headphone. Background Technology

[0002] Over-ear headphones, as the name suggests, are worn on the head and not inserted into the ear canal, unlike in-ear earbuds. They consist of two parts: a headphone with a signal receiver and an amplifier (usually dynamic or planar magnetic). Sound quality and tone can be improved and adjusted using a headphone amplifier.

[0003] Current headphones, worn for extended periods, are prone to breakage due to the large size of the head's connecting structure. Conversely, they are also prone to falling off frequently due to small head sizes. Furthermore, current headphones are inconvenient to store and transport, being too bulky and difficult to carry. This also significantly reduces costs during transportation and storage. Therefore, we propose a multi-joint adjustable, retractable headphone design. Utility Model Content

[0004] The purpose of this invention is to provide a multi-joint adjustable and retractable headphone to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a multi-joint adjustable and retractable headphone, comprising: Two earphones are provided, with slots on the opposite sides of each earphone. A left headband unit and a right headband unit are respectively installed in the two slots. A multi-joint adjustment mechanism is provided between the left and right headband units. The multi-joint adjustment mechanism is composed of multiple independent arc-shaped headband units that are hinged sequentially along the length direction. Adjacent headband units are connected by a bidirectional rotating joint assembly. The bidirectional rotating joint assembly can rotate up and down along the width direction of the earphone and swing left and right along the length direction of the earphone. A circular locking button is provided on the outer wall of the bidirectional rotating joint assembly. Through the coordinated adjustment of the multi-joints and the swing of the ear shell axis, the headband can adaptively fit more of the curved contours of the head.

[0006] In this technical solution, the headband multi-joint adjustment mechanism is formed by unfolding multiple independent arc-shaped headband units. Simultaneously, the bidirectional rotating joint assembly allows for vertical rotation along the width of the headphones and horizontal swing along the length, ensuring the headband multi-joint adjustment mechanism can be worn on the user's head. This allows the two headphones to be worn on the user's ears, while the headband multi-joint adjustment mechanism itself is worn on the head. The extension and retraction of the headband multi-joint adjustment mechanism, along with the insertion of the left and right headband units into their corresponding slots, also allows for overall headband size adjustment in conjunction with the arc-shaped headband units, providing bidirectional adjustment. This allows the entire device to fit different users. Furthermore, when retracted, the entire device is small and portable, making it very convenient for travel and storage. Moreover, the overall device significantly reduces costs during transportation and storage.

[0007] In the above technical solution, the bidirectional rotating joint assembly further includes a fixed base and a rotating shaft. The fixed base and the left head beam unit are integrally formed, and the rotating shaft is connected to the right head beam unit through a tension structure.

[0008] In this technical solution, the structural stability of the fixed base and the left head beam unit, and the structural stability of the rotating shaft and the right head beam unit are ensured.

[0009] In the above technical solution, the arc-shaped head beam unit is made of reinforced composite plastic material, and arc-shaped slots and arc-shaped blocks are respectively provided at both ends of the arc-shaped head beam unit, and the arc-shaped blocks and arc-shaped slots are inserted and matched.

[0010] In this technical solution, when adjacent arc-shaped head beam units are connected, the arc-shaped locking block is fully embedded in the arc-shaped locking groove. The arc-shaped head beam unit is made of reinforced composite plastic material to ensure that the arc-shaped head beam unit has sufficient toughness and ensures the stability of the overall structure.

[0011] In the above technical solution, the bidirectional rotating joint assembly has a vertical rotation angle of 0-60° along the width direction of the earphone.

[0012] In this technical solution, the bidirectional rotating joint assembly is ensured to be able to rotate up and down along the width of the earphone, and the rotation angle is adjustable from 0 to 60°, which facilitates the use of the overall device by the user.

[0013] In the above technical solution, the bidirectional rotating joint assembly swings left and right at an angle of 0-60° along the length of the earphone.

[0014] In this technical solution, the bidirectional rotating joint assembly is ensured to swing left and right along the length of the earphone, and the angle of left and right swing is adjustable from 0 to 60°, making it convenient for personnel to use the whole device.

[0015] The beneficial effects of this utility model are: This multi-joint adjustable and retractable headphone features a headband adjustment mechanism comprised of multiple independent curved headband units. Simultaneously, the bidirectional rotating joint components allow for vertical rotation along the headphone's width and horizontal swing along its length, ensuring the headband can be comfortably fitted to the user's head. This allows the two earpieces to be worn on the user's ears, while the headband itself rests on the head. The extension and retraction of the headband adjustment mechanism, along with the insertion of the left and right headband units into their corresponding slots, allows for overall headband size adjustment in conjunction with the curved headband units, providing bidirectional adjustment. This allows the entire device to fit different users. Furthermore, when retracted, the device is compact and portable, making it convenient for travel and storage. It also significantly reduces transportation and storage costs. Attached Figure Description
