| description | An electroacoustic transducer (1) includes a base (24) and magnetic core (22) a diaphragm (20) 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) a coil (23) disposed around the magnetic core a coil bobbin (30) for holding the coil (23), a housing (10) for receiving the above-mentioned members, a filler (19) applied to an external surface side of the base (24), and lead terminals (41 and 42) for supplying an electric current. The lead terminals (41 and 42) have protrusion portions (41a and 42a, protruding into an internal surface side of the base (24) in the axial direction of the coil. A coil wire (23a) is wound around the protrusion portions (41a and 42a) so as to be connected to the lead terminals (41 and 42). |
