Electroacoustic transducer

摘要

There is provided an electroacoustic transducer (1) including a base (24) made of magnetic material, a magnetic core (22) made of magnetic material and provided erectly on the base (24), a diaphragm (20) made of magnetic material and supported with a gap between the diaphragm and a forward end of the magnetic core, a magnet (25) constituting a magnetic circuit together with the base (24), the magnetic core (22) and the diaphragm (20) so as to provide a magnetostatic field, a coil (23) disposed around the magnetic core for applying an oscillating magnetic field to the magnetic circuit, a coil bobbin (30) for holding the coil (23), and a housing (10) for receiving these above-mentioned members. The coil bobbin (30) is integrally molded with the magnetic core (22) and the base member (24). <IMAGE>
