摘要: A speaker with a built-in filter used for a digital amplifier is provided. The speaker with the built-in filter includes an inductor wound on an outer circumferential surface of a pillar passing through a magnet. The speaker in accordance with the present invention may be directly connected to the digital amplifier without an additional low pass filter interposed therebetween, enabling a smaller and lighter digital amplifier.
