ABSTRACT:
A network mounting device in a coaxial type speaker including a woofer having a diaphragm, a center pole for forming a magnetic circuit of the woofer, and a tweeter mounted on a front end of the center pole. The network mounting device includes a frame for supporting an outer circumference of the diaphragm of the woofer, a plate for forming the magnetic circuit, a network for dividing a frequency and feeding divided frequencies to the woofer and the tweeter, and a substrate for mounting the network thereon, which substrate is sandwiched between the frame and the plate. The coaxial type speaker can be assembled easily, and the workability for wiring of the network can be improved.
