Abstract
A microphone transducer includes a magnet, a yoke disposed around the magnet, an inner insulator provided between the magnet and the yoke, an outer insulator provided around the yoke, a voice coil provided around an upper portion of the magnet, and a diaphragm having a central convex portion and an annular convex portion which encircles the central convex portion. The central convex portion has a periphery which is attached to the voice coil. The annular convex portion has a periphery which is attached to the outer insulator. A noise reducing member includes a rigid annular mounting plate which is attached to the periphery of the annular convex portion of the diaphragm, and a flexible cushioning ring having a top side attached to the mounting plate and a bottom side attached to the outer insulator.
Claims5
A handheld dynamic microphone including a housing, a microphone transducer disposed within said housing and including a magnet, a yoke disposed around the magnet, an inner insulator provided between the magnet and the yoke, an outer insulator provided around the yoke, a voice coil provided around an upper portion of the magnet, and a diaphragm having a central convex portion and an annular convex portion which encircles the central convex portion, the central convex portion having a periphery which is attached to the voice coil, the annular convex portion having a periphery which is attached to the outer insulator, wherein the improvement comprises:
- a noise reducing member for reducing noise signals generated by friction between the hand of a user of said microphone and said housing of said microphone, said noise reducing member including a rigid annular mounting plate having first and second sides, said first side being attached to the periphery of the annular convex portion of the diaphragm, and a first flexible cushioning ring having a top side attached to said second side of said mounting plate and a bottom side attached to the outer insulator.
