A method for fabricating a speaker is disclosed. The speaker is equipped with a case having a through cavity, an inner surface forming the cavity and an outer surface, a magnetic bowl coupled to the case, a magnet positioned in the magnetic bowl, a pole plate covering the magnet, a magnetic gap formed by the magnet and the magnetic bowl, a diaphragm supported by the case and vibrating along a vibrating direction, a voice coil connected to the diaphragm, and a hearing aid coil formed on the case. The method includes the steps of: providing a case made of thermoplastic doped with organometallic additive; activating the organometallic additive in the case by a laser beam for forming initial pattern of the hearing aid coil in the inner surface of the case; and bathing the case in copper solution for providing the initial pattern with copper plating layer.
