模拟分频器是音箱内的一种电路装置，用以将输入的模拟音频信号分离成高音、中音、低音等不同部分，然后分别送入相应的高、中、低音喇叭单元中重放。之所以这样做，是因为任何单一的喇叭都不可能完美的将声音的各个频段完整的重放出来。-The analog divider speakers within a circuit device to the input analog audio signal is separated into different parts of the treble, alto, bass, and then were sent to the corresponding high, Woofer replay. The reason for doing so is because any single speaker can not perfect the sound of each band complete reproducing.
