A case is formed of thermoplastic resin, and includes an upper case and a lower case . The case accommodates a pole piece , a coil , a magnet , a diaphragm , and so on. The pole piece includes an core and a base , and placed on the lower case . There are integrally formed on an upper face of the lower case , a wall for defining a mounting position of the pole piece , a projection for preventing a conductive wire drawn our from the coil from getting in touch with the base , and a bobbin part for the conductive wire to be wound therearound. A height of the projection is set at an equal or larger value to or than a height of a surface of the base , and a contact of the conductive wire with the base can be avoided by the projection
