A speaker is a device that converts electrical signals into sound, mainly composed of components such as a diaphragm, magnetic ring, and conductive coil. An electrical signal generates a magnetic field in a conductive coil, which causes the diaphragm to move and produce sound.
The working principle of a speaker is based on the propagation of vibration. The vibration of the diaphragm converts electrical signals into sound waves in the air, achieving amplification and propagation of sound. Speakers can be used in various occasions, such as audio equipment, television, radio, etc., to convert electronic signals into sound and convey the sound to the audience.
According to their different working principles and application scenarios, speakers can be divided into many types, such as magnetic speakers, electric speakers, oscillating speakers, and so on. Driven by modern technology, the technology of speakers is also constantly advancing, gradually achieving higher sound quality and wider application areas.
