ABSTRACT:
An enameled wire with an insulating coated layer of high laser beam absorption and with a melting layer transparent to the laser beam. The high laser beam absorption makes stripping of the insulating coating layer easy without increasing an output of the laser beam extremely large. As a result, possible wire breakage at soldering can be avoided and soldering reliability improves in assembling the small electro-acoustic transducers. An electro-acoustic transducer of the present invention is provided in the resin-molded body with an empty space in at least a place underneath a portion of soldering land, on which a laser beam is irradiated. Apparatus comprising the electro-acoustic transducer of the present invention can provide a well-stabilized soldering quality and a high reliability.
