PROBLEM TO BE SOLVED: To provide a multicoil, a voice coil and an electroacoustic transducer which allow for both high performance in voice characteristics and low cost easily.SOLUTION: A multicoil 110 is constituted of coil element A, coil element B and coil element C corresponding to the quantization bit number n of a digital voice signal. The coil element A, coil element B and coil element C are coil wires of the same length. The multicoil 110 has a winding structure where the coil wires of the coil element B and coil element C are wound a plurality of number of turns in the coil vibration direction α, and laminated in the magnetic flux direction &bgr;. |
