A. Open bottom: easy to see the inner layer through the mesh.
Solution: It can be covered by dust-proof nets, sponges, etc.
B. Vibrato: It is easy to produce vibration and abnormal noise with the shell.
Solution: You can paste EVA, sponge and other buffers.
C. Connection: The position where the speaker mesh and other parts are connected is prone to problems such as gaps and step differences.
Solution: Be more familiar with the molding and assembly characteristics of the speaker net, and use the structure to reasonably avoid or improve these problems during structural design.
