PROBLEM TO BE SOLVED: To provide a voice coil, compact and sufficiently securing a driving force of the diaphragm, improving reproduction performance in high-frequency, configured so that a plurality of voice coils is disposed at one diaphragm, and to provide an electroacoustic transducer including the same.SOLUTION: The electroacoustic transducer of a dynamic type that is disposed in a magnetic circuit and outputs acoustic waves by driving a diaphragm 13 in accordance with an input digital signal includes a plurality of voice coils 12 to which digital signals are individually input. The voice coils 12 are formed of stranded wires 121 formed by twisting a plurality of conductor wires.SELECTED DRAWING: Figure 3 |
