Patent attributes
There is provided a dynamic microphone which prevents, with a simple configuration, the lead of a voice coil from breaking even when a strong sound pressure or the like presses a diaphragm to a magnetism generating circuit. The dynamic microphone includes a diaphragm 11 having a voice coil 12 attached to a boundary between a center dome 11a and a sub dome 11b, and a magnetism generating circuit 20 which has a pole piece 22 provided on one pole of a permanent magnet 21, a ring yoke 24 provided on the other pole of the permanent magnet 21, and a magnetic gap formed between the pole piece 22 and the ring yoke 24, the voice coil 12 being supported in the magnetic gap so as to vibrate through the diaphragm 11, the voice coil 12 having a lead 12a wired along the inner surface of the sub dome 11b, wherein the lead 12a of the voice coil 12 is elastically held on the sub dome 11b at least through an elastic layer 30 applied to the inner surface of the sub dome 11b adjacent to the voice coil 12.
