Electroacoustic device refers to the device that converts electricity and sound into each other. It uses electromagnetic induction, electrostatic induction, or piezoelectric effect to complete the electroacoustic conversion, including speakers, headphones, microphones, cartridges, etc.
The speaker is one of the electro-acoustic transducers. Electroacoustic energy conversion is a device that converts electrical energy into acoustic energy or converts acoustic energy into electrical energy and performs the same frequency conversion. This conversion is not a direct conversion of electrical and acoustic energy, but rather a mechanical system.
Due to different starting points and different cut-in angles, speakers can be classified in different ways.
Commonly used classification methods
There are classifications based on transduction methods;
Classification by working principle;
Classification by radiation method;
Classified by purpose;
Classification by diaphragm shape;
Classified by combination.
