Description

Technical Field

[0001] This utility model relates to the field of headphone technology, and in particular to an ear cup assembly for over-ear headphones. Background Technology

[0002] In related technologies, the earcup components of over-ear headphones typically require covering the foam with an earcup skin, and then fixing the earcup skin to the earcup bracket using adhesive or welding. The adhesive or welding manufacturing process for the earcup skin requires the additional purchase of adhesive or welding equipment, resulting in high manufacturing costs. Furthermore, the earcup skin or foam cannot be replaced individually later; only the entire earcup assembly can be replaced, leading to significant resource waste.

[0003] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the prior art and its main objective is to provide an ear cup assembly for headphones, effectively solving the technical defects of the prior art, which is that the ear cup assembly uses adhesive or welding manufacturing processes, resulting in high manufacturing costs and waste of resources.

[0005] This utility model provides an ear cup assembly for a headset, including a sponge, an ear cup skin covering the outer surface of the sponge, and an ear cup bracket for mounting the ear cup skin. The earmuff skin covers the front surface and peripheral side of the sponge, and the end of the earmuff skin is provided with a radial clamping edge, which is arranged parallel to the rear side of the sponge; the front surface of the earmuff bracket is detachably equipped with a fastening bracket, which has a support edge, and the support edge is clamped on the rear surface of the sponge and the front surface of the radial clamping edge. When the fastening bracket is fastened and installed on the front surface of the earmuff bracket, the support edge and the front surface of the earmuff bracket can clamp the radial clamping edge.

[0006] The beneficial effect of the earcup assembly of the headphones provided by this utility model is that, when assembling the earcup assembly, the earcup skin is covered with the front surface and peripheral side of the sponge, then the support edge is placed between the rear surface of the sponge and the front surface of the radial clamping edge, and finally the fastening bracket is fastened and installed on the front surface of the earcup bracket, so that the support edge and the front surface of the earcup bracket clamp the radial clamping edge, thus completing the installation of the entire earcup assembly.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figures 1 to 6 The earcup assembly 100 of the over-ear headphones provided in this application embodiment will now be described. The earcup assembly 100 of the over-ear headphones includes a sponge 10, an earcup skin 20, and an earcup support 30.

[0025] The ear cup skin 20 covers the outer surface of the sponge 10 and is installed on the ear cup support 30. The ear cup skin 20 covers the front surface and peripheral side of the sponge 10, and the end of the ear cup skin 20 is provided with a radial clamping edge 21, which is arranged parallel to the rear side of the sponge 10. The front surface of the ear cup support 30 is detachably equipped with a fastening bracket 31, which has a support edge 311. The support edge 311 is clamped to the rear surface of the sponge 10 and the front surface of the radial clamping edge 21. When the fastening bracket 31 is fastened and installed on the front surface of the ear cup support 30, the support edge 311 and the front surface of the ear cup support 30 can clamp the radial clamping edge 21.

[0026] When assembling the earmuff assembly, the earmuff skin 20 is wrapped around the front surface and peripheral side of the sponge 10, the support edge 311 is placed between the rear surface of the sponge 10 and the front surface of the radial clamping edge 21, and finally the fastening bracket 31 is fastened and installed on the front surface of the earmuff bracket 30, so that the support edge 311 and the front surface of the earmuff bracket 30 clamp the radial clamping edge 21, thus completing the installation of the entire earmuff assembly. Compared with existing technologies, this structure offers several advantages. First, by providing a support edge 311 between the sponge 10 and the radial clamping edge 21, the earcup skin can be fixed by the support edge 311 and the earcup bracket 30 clamping the radial clamping edge 21 after the fastening bracket 31 is fastened to the earcup bracket 30. This eliminates the need for adhesive or welding processes, simplifying the manufacturing process of the earcup assembly, reducing manufacturing costs, and improving production efficiency. Second, since the earcup skin 20 and the earcup bracket 30 are detachably installed, if the earcup skin 20 or the sponge 10 becomes dirty or damaged, the fastening bracket 31 can be removed from the earcup bracket 30 to replace the earcup skin 20 or the sponge 10. This simple and convenient installation and removal enhances the ease of replacement for users. Furthermore, it allows for the replacement of individual components without replacing the entire earcup assembly, saving resources and avoiding unnecessary waste.

[0027] In some embodiments, the sponge 10 has a circular cross-section and a sound outlet 101 extending through its front surface; the ear cup skin 20 has a plurality of sound outlet holes 201 at the location of the sound outlet 101, and the plurality of sound outlet holes 201 extend through the front and rear surfaces of the ear cup skin 20; the ear cup support 30 includes a rear shell 32 and a front cover 33, the front cover 33 is detachably installed at the front end of the rear shell 32 and encloses a mounting cavity 34 for installing a sound unit; the front surface of the front cover 33 has a plug-in protrusion 331, the front surface of the plug-in protrusion 331 has a sound hole 334, the sound hole 334 extends forward through the front surface of the plug-in protrusion 331, extends backward through the rear surface of the plug-in protrusion 331 and connects to the mounting cavity 34. The sound unit installed in the mounting cavity 34 can transmit sound outward through the sound hole 334, the sound outlet 101 and the sound outlet 201; while the front surface of the ear cup skin 20 is the surface that rests against the human ear.
