Description

Technical Field

[0001] This utility model relates to the technical field of over-ear headphones, and more particularly to a wireless over-ear headphone with adjustable headphone position. Through the adjustable assembly structure between the headband and the two earphones, the height position of the two earphones can be easily adjusted. Background Technology

[0002] Modern headphones, whether wired or wireless, all feature a semi-circular headband and two over-ear headphones attached to either end of the headband. To accommodate different users, an adjustment mechanism is necessary to adjust the height of the over-ear headphones. Current technology almost always integrates this adjustment mechanism into the headband itself. For example, the headband is divided into a crossbeam and two adjustment rods (at least three main components). The two adjustment rods are movably assembled at both ends of the crossbeam, and the over-ear headphones are then fixed to the lower ends of the two adjustment rods, thus allowing for height adjustment of the over-ear headphones.

[0003] The headband example above is just a simple illustration of an adjustment mechanism, which requires at least three main components. Other, more complex adjustment mechanisms (as shown in existing technical literature) may require more than a dozen parts to assemble a set of adjustable headbands. Therefore, existing headband adjustment mechanism technology results in complex assembly procedures, increased manufacturing costs, difficulties in controlling component tolerances, and a tendency for loosening or inaccurate positioning due to mechanical wear over prolonged use. Especially in complex structures, users find it difficult to operate intuitively during actual wear, reducing ease of use and overall product durability. Furthermore, the large number of parts also increases the product's size and weight, compromising comfort during extended wear. Therefore, further improvements are still necessary.

[0055] See Figure 1 , Figure 2 and Figure 3 As shown, the present invention discloses a wireless over-ear headphone with adjustable earpiece position. A preferred embodiment includes a headband 10 and two earpieces 20, wherein:

[0056] The headband 10 has a single-piece molded arc-shaped rod 11, with both ends branching downwards to form two earphone rods 12, creating an inverted Y-shaped structure on the side of the headband 10. The two earphone rods 12 are made of plastic, which can be the same plastic as the arc-shaped rod 11 or a different plastic, allowing the earphone rods 12 to open and close flexibly. A downward-facing accommodating space 13 is formed between the two earphone rods 12 for assembling the earphones 20. A row of interlocking teeth 14 is integrally molded on the corresponding inner surfaces of the two earphone rods 12, used to fix the sides of the earphones 20 and allow the earphones 20 to be adjusted vertically. The integral molding structure of the arc-shaped rod 11, the two earphone rods 12, and the interlocking teeth 14 of the headband 10 simplifies the number of parts in the headband 10, enabling rapid assembly and reducing costs.

[0057] The two earphones 20 are respectively disposed in the accommodating space 13. Each earphone 20 has a locking protrusion 21 on both sides. The locking protrusion 21 engages with the corresponding earphone rod 12's concave and convex teeth 14. Through the elastic opening and closing structure of the earphone rod 12, the two earphones 20 can be adjusted up and down relative to the headband 10. This structural design allows the user to intuitively and directly adjust the height of the two earphones 20 to suit the user's personal wearing needs.
