Abstract

Miniature inductor used as positive-booster coil in a control circuit of a piezoelectric buzzer or the like, comprises a closed magnetic circuit formed of two cores (36, 37) covering the outer periphery of a coil (35) wound around the internal cores. A pair of windows (38) are cut out from the outer periphery of each of the said cores (36, 37). Junction plates (31) arranged on the inner face of the back of one core (37) have connection blocks (32) projecting respectively outside these windows (38) in such a way that the connection blocks (32) are adapted so as to be bent (at 33) above one another, and so that the end (39) of each conductive wire of the coil (35) is guided through the cut-out window (38) and interposed between the bent (at 33) connection blocks (32) and is thus connected to the said connection blocks. <IMAGE>
