Description

Technical Field

[0001] The utility model relates to the technical field of head-mounted headphones, in particular to a grinding device for processing ear shells. Background Art

[0002] Headphones, as the name implies, are worn on the head, not inserted into the ear canal, and are different from in-ear earplugs. They consist of two parts, a signal transmitter and headphones with signal receiving and amplifying devices (usually dynamic). The transmitter is connected to the signal source, and a preamplifier or headphone amplifier can also be connected in front of the transmitter to improve the sound quality and adjust the timbre.

[0003] During the production and assembly of headphones, the ear shells need to be processed and polished to facilitate subsequent processing. However, the existing ear shell processing and polishing devices can only process the outer surface of the ear shell better when in use, but cannot polish the inner surface of the ear shell. The polishing position needs to be constantly changed to achieve polishing of different surfaces, which wastes workers' time and is not conducive to polishing.

[0004] Therefore, we propose a grinding device for ear shell processing. Utility Model Content
