Description

Technical Field

[0001] This utility model relates to the field of headphone technology, specifically to a non-adhesive headphone earcup that prevents it from falling off. Background Technology

[0002] Over-ear headphones, as the name suggests, are a type of headphone worn on the head rather than inserted into the ear canal. Over-ear headphones typically consist of two parts: a signal transmitter and headphones (usually dynamic drivers) with signal reception and amplification. The transmitter is connected to a signal source, and a preamplifier or headphone amplifier can be connected before the transmitter to improve sound quality and adjust timbre.

[0003] When using headphones, memory foam is placed in the area that contacts the ears. Memory foam is usually installed by gluing it on, but after prolonged use, it is prone to damage and needs to be replaced. However, gluing makes it inconvenient to replace the memory foam. Therefore, there is a need for headphones that allow for easy, glue-free installation of the memory foam. Utility Model Content

[0004] The purpose of this invention is to provide a non-adhesive, non-detachable headphone earcup that facilitates the non-adhesive installation of memory foam, thus solving the problem that replacing memory foam is difficult when using adhesive methods.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a non-adhesive, non-detachable headphone earcup, comprising memory foam, a limiting ring, a shell, a connecting ring, and a connecting block. Limiting grooves are formed in the middle of both sides of the shell. The headphone body is fixed inside the middle of the shell. Four springs are fixed in a circular array inside the shell on the outer side of the headphone body. The limiting ring is fixed to one end of each spring. The memory foam is fixed to one side of the limiting ring. A protective film is fixed inside the memory foam on the side of the limiting ring. A retaining ring is fixed to the side of the limiting ring away from the memory foam. Limiting posts are welded to the middle of both ends of the retaining ring. The limiting ring is sleeved inside the shell via the retaining ring, and the limiting posts are movably installed within the limiting grooves.

[0006] Preferably, the connecting block is fixed at the middle of the side of the outer shell away from the memory foam, and connecting posts are fixed at the middle of both sides of the connecting block. The two ends of the connecting ring are movably mounted on the connecting posts, and the upper outer ends of the two connecting rings are connected by connecting rings.

[0007] Preferably, the limiting groove is right-angled, and the outer diameter of the limiting post is adapted to the inner width of the limiting groove.

[0008] Preferably, the outer diameters of the fixing ring and the memory foam are equal, and the outer diameter of the fixing ring is larger than the outer diameter of the retaining ring.

[0009] Preferably, the outer diameter of the retaining ring is smaller than the inner diameter of the outer shell, the depth of the retaining ring is smaller than the inner depth of the outer shell, and the earphone body is located inside the retaining ring.

[0010] Preferably, the limiting ring is movably installed inside the outer shell, and the limiting ring is sleeved on the outside of the earphone body.

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

[0012] 1. This utility model, by incorporating a spring and a retaining ring, facilitates the adhesive-free installation of memory foam. The memory foam is installed inside the outer casing via the retaining ring, with the limiting post corresponding to the limiting groove. By pressing, the limiting post enters the bottom of the limiting groove. Simultaneously, by rotating the retaining ring clockwise, the limiting post moves to the other end of the right angle of the limiting groove. The cooperation between the limiting groove and the limiting post limits the retaining ring, which facilitates the installation of the memory foam. Furthermore, the stability of the memory foam installation is improved by the action of the spring and the retaining ring. When replacing the memory foam, the counterclockwise rotation of the retaining ring facilitates the removal of the memory foam. Attached Figure Description
