Description

Technical Field

[0001] This utility model belongs to the field of speaker shell production technology, and specifically relates to a mold for punching out sound holes on an arc. Background Technology

[0002] The sound vents on a speaker allow air to circulate between the inside and outside, enabling the air inside the speaker to resonate with the outside air. Some creatively designed Bluetooth speakers use a cylindrical shape with sound vents around the perimeter, allowing sound to propagate evenly in all directions, creating 360-degree omnidirectional audio coverage.

[0003] In the production of speaker enclosures, the sound holes are typically created using an etching process. First, a layer of photosensitive ink is evenly coated onto the metal surface. Then, film and ultraviolet light exposure cause a chemical reaction in the ink, forming a latent image of the sound hole pattern. Next, a developer is used to dissolve the unexposed photosensitive ink, exposing the metal surface to be etched. The metal is then immersed in an etching solution, where the exposed metal surface is corroded, forming the sound holes. The entire sound hole manufacturing process is time-consuming and costly.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0045] When the punch 702 punches the sound hole of the product, the punch 702 can penetrate the product and directly move into the corresponding sound hole 705. The arrangement of the sound hole 705 avoids the direct contact of the punch 702 with the outer surface of the support cylinder 2 during punching of the product, so that the bottom end of the punch 702 is not damaged. At the same time, the debris generated during punching can fall into the inside of the support cylinder 2 through the sound hole 705. The bottom of the support cylinder 2 is provided with a collecting groove. When the product is taken out of the support cylinder 2, the debris inside the support cylinder 2 can directly fall from the inside of the support cylinder 2 through the collecting groove.
