Speaker horn, as the core component in audio equipment, determines the overall sound quality effect of sound, and speaker horn voice coil, as its "heart", plays an extremely important role in the overall performance of speaker horn. Voice coils made of voice coil wires of different materials. The sound quality from the speakers is also different. At present, the material of the voice coil wire used for the speaker horn voice coil is mainly copper wire and aluminum wire, so is it better to use copper wire or aluminum wire for the voice coil of the speaker horn?

Copper wire voice coils have good bearing capacity and can withstand large power input and output. Like ordinary mid-bass speakers, copper wire voice coils are mostly used. In addition, the heat dissipation efficiency of the voice coil can be increased by strict arrangement without leaving gaps. The aluminum wire voice coil is light in weight and can obtain better transient response. Generally, it is mainly used in tweeters, and the high frequency is bright and thorough. However, in terms of bearing capacity and durability, it is not as good as copper wire. The aluminum wire is easy to oxidize for a long time, which affects the sound quality of the speaker.
