<p>PROBLEM TO BE SOLVED: To provide a dynamic microphone in which the mechanical impedance of a shock mount can be adjusted with a simple structure, thereby effectively reducing vibration noise.SOLUTION: A dynamic microphone includes a microphone unit 110, an inner cylinder 120 integrally mounted to a rear end portion of the microphone unit, and a microphone housing 20 as a microphone grip. A predetermined portion of the inner cylinder 120 is supported within the microphone housing 20 via an annular shock mount member 31 made of an elastic body. A groove 311 is formed in the shock mount member 31 over the whole circumference thereof, an ultraviolet curing resin 40 is filled into the groove 311, the ultraviolet curing resin having viscosity in uncured and having elasticity after cured, and the impedance Zs of the shock mount member 31 is adjusted so that vibration noise is minimized by changing the ratio between a cured part 41 and an un-cured part 42 depending on the irradiation amount of ultraviolet rays.</p> |
