Due to their relatively large size and design space, headphones offer advantages in achieving high-quality audio and versatility, making them the preferred choice for many audio enthusiasts and professional users.

[0003] The earcups are the part of over-ear headphones that comes into direct contact with the user's ears, and they have a significant impact on the acoustic performance of the headphones. When wearing existing earcups, they can cause pressure on the ears, which can lead to discomfort after prolonged use and result in a poor user experience. Utility Model Content

[0004] The purpose of this invention is to provide a headphone earcup with noise reduction function, which has the advantages of noise reduction and a better fit to the human ear, thus solving the problem that current earcups cause pressure on the ear when worn, resulting in a poor user experience.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a headphone earmuff with noise reduction function, comprising an earmuff body, the earmuff body comprising an outer shell, the outer shell having a sponge inside, a bottom membrane attached to one side of the outer shell, and an inner edge plate on the other side, a guide surface on the outer side of the inner edge of the edge plate, and outward expansion grooves on both the upper and lower sides of the guide surface, and a fixing mechanism on the side of the bottom membrane away from the outer shell.

[0006] Preferably, the outer shell is in the shape of a ring, and the thickness of the outer shell is 2~2.5cm. The inner edge of the rim plate extends out of the inner edge of the outer shell, and the side of the rim plate is flush with the side of the outer shell.

[0007] Preferably, the two outer expansion grooves are respectively placed at the upper and lower ends of the rim plate and are staggered. The rim plate and the two outer expansion grooves together form an arc-shaped ear chamber that conforms to the ergonomics of the human ear.

[0008] Preferably, the fixing mechanism includes a ring plate, the outer edge of the ring plate is flush with the outer edge of the outer shell, and the inner edge of the ring plate is provided with a limiting strip, the outer edge of the limiting strip is provided with a limiting strip for the card and the earphone.

[0009] Preferably, the limiting strip is composed of a guide portion and a limiting portion, wherein both the guide portion and the limiting portion are annular columnar structures with a fan-shaped cross-section, and the fan-shaped diameter of the guide portion is greater than the fan-shaped diameter of the limiting portion.

[0010] Preferably, a plurality of sealing strips are provided on the side of the ring plate away from the outer shell and on the outer side of the limiting plate, and the cross-section of each sealing strip is semi-circular.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model, by setting up an outer shell, sponge, edge plate, guide surface, and outer expansion groove, uses a sponge to support the outer shell and an edge plate inside the outer shell to fit the head, which helps the headphones to better seal the ear canal, reduce sound leakage, improve the low-frequency response of the sound and the clarity of the overall sound quality. The guide surface set on the edge plate can improve the wearing comfort when wearing the headphones. The outer expansion grooves set at the upper and lower ends of the edge plate can make the earcups more ergonomic, making the user feel more comfortable and thus extending the use time of the headphones.

[0013] 2. This utility model, by setting a ring plate, a limiting plate, a limiting strip, a guide part, a limiting part and a sealing strip, can increase the tightness of the connection between the earcups and the headphones by setting the sealing strip on the ring plate and the limiting plate, and avoid sound leakage. The limiting strip is composed of guide parts and limiting parts with different diameters, which facilitates the installation of earcups and can prevent the earcups from falling off during use.
