Abstract

PURPOSE:To improve the low range properties in a simple structure by forming plural number of volume rooms which can store the air at the back of the diaphragm and then securing the linkage for the volumetric space via the inertance tube featuring the fixed vibration equivalent mass. CONSTITUTION:Magnetic circuit 22 of dynamic microphone 21 consists of magnet 23, yoke 24 and center pole 24 each. Then inertance ring 26 is attached to the inside of yoke 24 with voice coil 28 provided into gap 27, and then coil 28 is connected to diaphragm 29. Then 1st and 2nd volume rooms 41 and 42 which can store the air are formed at the back of diaphragm 29. Room 41 is linked to the inside of circuit 22 via resistance substance 36, and room 42 is located at the back of room 41. Then the linkage is given between rooms 41 and 42 via holes 47 and 48 of inertance tube 45 of the equivalent mass featuring the fixed low range resonance frequency. Thus the low range frequency properties can be enhanced in a simple structure.
