Abstract
The invention provides a method for manufacturing a battery cover, a battery cover and a terminal, and relates to the technical field of electronic equipment. It is designed to solve the problem of blocking the sound outlet of the speaker and grinding the outer surface of the metal battery cover when the electronic equipment with a metal battery cover with a smooth arc surface or a smooth plane is placed on a desktop or a plane in the prior art. . The manufacturing method includes: providing a metal cover plate body, manufacturing a plurality of speaker sound holes and a plurality of through holes on the metal cover plate body; manufacturing a plurality of wear-resistant support parts; Assembled and fixed into the through hole of the metal cover body, each wear-resistant support part corresponds to a through hole, wherein the wear-resistant support part protrudes from the outer surface of the metal cover body. By assembling and fixing the wear-resistant support part manufactured separately to the battery cover, the present invention ensures the normal playback of the external sound from the speaker of the electronic equipment, and protects the appearance effect of the battery cover.
Description
technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a method for manufacturing a battery cover, a battery cover and a terminal. Background technique [0002] With the continuous development of consumer electronic devices, more and more products require the appearance of metal battery covers. In order to achieve a better appearance, the surface of the metal battery cover often requires CNC (Computer numerical control, computer numerical controlmachine tool) to process the outer surface and then perform grinding or wire drawing surface treatment. Due to the characteristics of the above surface treatment process, the surface of the battery cover after processing is smooth or flat, and it is impossible to achieve the shape of local wear-resistant bumps. Therefore, when the device is placed on a desktop or a flat surface, the sound outlet of the speaker will be blocked, causing the sound to be unable to be transmitted. A...
