Electroacoustic transducer and method of winding coil therein

摘要

The present invention provides an electroacoustic transducer which can increase the winding efficiency of a coil on a pole and allows the automation of a coil winding process. The present invention relates to an electroacoustic transducer for vibrating a diaphragm by a magnetic field generated in response to an inputted electric signal to convert the electric signal into sound. The coil is wound around the pole along its entire length. However, at the pole tip, the coil is formed to have an outwardly diverging, frusto-conical recess that exposes the pole tip.
