According to the transducer mechanism and structure: divided into dynamic type (electric type), capacitive type (electrostatic type), piezoelectric type (crystal or ceramic), electromagnetic type (compression spring type), ion type and pneumatic type. Among them, electric speakers are widely used due to their good electroacoustic performance, strong structure and low cost.
According to the sound radiation material: divided into paper cone type, horn type, diaphragm type, etc.
According to the working frequency: divided into bass, midrange and tweeter speakers, and some are also divided into recorder-specific, TV-specific, ordinary and high-fidelity speakers according to specific uses.
