Speakers are an important component in audio equipment, and their performance has a great impact on the sound quality.
Speakers are widely used in various electronic and electrical devices that make sound, such as televisions, computers, mobile phones, car multimedia, etc.
Depending on the use requirements, speakers can be active (requires external power) or passive (does not require external power).
Speakers can also be divided into built-in speakers and external speakers. Built-in speakers, such as the speakers built into MP4 players, are convenient for users to listen to the sound directly; external speakers usually refer to speakers, which are used to provide greater sound output and better sound quality.
In summary, speakers, as an electroacoustic transducer, play a vital role in audio equipment.
