As we all know, electric guitar speakers and electric guitars have a symbiotic relationship. Electric guitars without speakers are basically decorations, because electric guitars themselves have no sound, or the sound is very small and can be almost ignored. However, the biggest difference between electric guitars and acoustic guitars (wooden guitars) is that electric guitars come with built-in pickups, which are composed of coils and permanent magnets. When playing electric guitars, the strings vibrate and cut magnetic lines to generate electronic signals of the same wavelength. However, these signals are weak, so these audio signals can only be amplified through the electric guitar speaker to achieve electro-acoustic conversion. This is the function of an electric guitar speaker!
