Buzzer is an integrated electronic buzzer that is powered by a DC power supply and is often used as a sounding component in circuits. According to their driving methods, they can be divided into two categories: active buzzers and passive buzzers, and the "source" in their names refers to the oscillation source. When in use, the active buzzer only needs to be powered on to the positive and negative poles to emit sound in a fixed frequency band; Passive buzzers need to be connected to audio signals in order to produce sound. By connecting audio signals of different frequencies, the passive buzzer can produce a sound that sounds like "Duolai Mi Fa Suo La Si". HW-512 is an active buzzer.
