摘要： The invention provides a multi-coil unit, a voice coil, and an electro-acoustic transducer. Improved performance in audio characteristics and reduced costs can be both pursued with a simple configuration. A multi-coil unit 110 includes a coil element A, a coil element B, and a coil element C corresponding to the number n of quantization bits of a digital audio signal. The coil element A, the coil element B, and the coil element C are coil wires of the same length. The multi-coil unit 110 has a winding structure in which the coil wires of the coil element A, the coil element B, and the coil element C are wound a plurality of times in a coil vibration direction α to be stacked in a radial direction β of the multi-coil unit.
