1. Tight fit: Generally, small bone tight fit is used, which is widely used and often used to hide screws. Screws must be used to fix and seal the main parts of Bluetooth audio, and the appearance of screws is generally avoided as much as possible. If you To disassemble a Bluetooth speaker with a speaker net, if no screws are found under the foot pads, lenses, and stickers, the screws are basically hidden under the speaker net. Many relatively simple Bluetooth audio speaker nets are often assembled as the last Large pieces are used for "covering the coffin".
This kind of fixing method, when the machine falls, the iron net is easy to warp or fall off. In the actual market, this method is used to fix the speakers of the speaker net. If the pure tight fit method is used to fix it, many machines often fall and cannot hold it for a few times. . If the tight fit is too tight, it will be more difficult to disassemble and install. Therefore, if you want to fix the speaker net firmly, this method is not the first choice. Even if you want to do it, it is usually combined with other fixing methods.
2. Pull the foot: After assembly, bend the foot on the side of the speaker net to hold the shell. It is widely used and can be straightened when disassembled. However, sometimes the structure will cause the foot hole to be right on the sealed cavity. Additional sealing is required. If there are many feet, it will take a lot of time to disassemble and assemble. In this way, it is firmly fixed and there is no problem of falling off.
3. Gluing: It is often used when sealing is required or when other fixing methods are not suitable. The disadvantage is that the speaker net is difficult to disassemble.
4. Buckle: This method is relatively rare, but I have encountered some companies that like to do this. On the side of the speaker net, bumps are punched to buckle the plastic shell, and it is forced to squeeze down. It is necessary to use the plastic shell for actual matching and debugging. The raised points ensure a secure fastening.
5. Clamping: Make a good positioning and then press and fix the upper and lower parts to save costs.
6. Screws: There is no need to introduce this method. In addition, some large outdoor speakers often use external screws to fix the speaker net.
7. Ironing glue: fixed by hot-melt plastic column, the strength of hot glue fixing is not very strong, and the column is basically useless after being disassembled once.
