Furthermore, the microphone can rotate according to actual needs, thus improving ease of use and assembly.

Description

Technical Field

[0001] This utility model relates to the field of headphones, and in particular to a microphone adjustment structure for headphones. Background Technology

[0002] Over-ear headphones are widely used in wireless communication, aerospace, and other fields due to their comfort and long wearing time. A typical over-ear headphone includes left and right earcups, a headband, and a microphone assembly. Because different users have different head shapes, over-ear headphones usually utilize a metal gooseneck adjuster to allow each user to position the microphone comfortably.

[0003] However, the existing rotating structure of the microphone boom is generally quite complex. For example, Chinese patent 202223236615.3 solves the problems of complicated assembly and high friction of existing headphone microphones by designing a rotatable integrated microphone roller structure, which achieves a more stable and wear-resistant headphone microphone installation and improves the user experience.

[0004] However, it still requires additional mounting screws for fixation, which affects assembly efficiency. Utility Model Content

[0005] The main purpose of this invention is to propose a microphone adjustment structure for headphones, which aims to make microphone size adjustment smoother and more precise, improve adjustment feel, and facilitate assembly.

[0006] To achieve the above objectives, this utility model proposes a microphone adjustment structure for a headset, comprising:

[0007] The housing has a through hole;

[0008] The rotating shaft, which is a hollow tube, is pivotally mounted on a through hole.

[0009] The side wall of the rotating shaft is provided with a through-hole for wires;

[0010] A rotating seat, wherein a rotating hole is provided in the middle of the rotating seat, the rotating hole is fitted onto the outer wall of the rotating shaft, the rotating seat is provided with a cable, the cable passes through the cable hole and extends into the housing through the hollow tube, and a microphone is provided on the peripheral wall of the rotating seat;

[0011] An outer cover is detachably installed at the top of the rotating shaft, and the inner side of the outer cover abuts against the outer wall of the rotating seat and provides predetermined damping.

[0012] In the actual design, the cooperation between the rotating shaft and the outer cover provides limiting damping for the rotating seat. At the same time, the cable hole of the rotating shaft and the hollow tube facilitate the cable laying of the microphone rod and also facilitate assembly. Meanwhile, the microphone rod can be rotated according to actual needs, which facilitates the ease of use and assembly. Attached Figure Description
