Description

Technical Field

[0001] The utility model relates to the technical field of speaker accessories, in particular to a speaker grid assembly. Background Art

[0002] A speaker is a device that can convert audio signals into sound. In layman's terms, it means that the speaker main box or subwoofer box has a built-in power amplifier, which amplifies the audio signal and then plays it back through the speaker itself, making the sound louder.

[0003] At present, many speakers on the market are usually equipped with a grid on the outside of the speaker body to decorate the appearance of the speaker body. This type of grid is usually composed of two disassembled parts on the left and right sides to form a barrel-shaped structure.
