Vocal microphones are most entertainers’ and engineers’ introduction to sound systems, their first point of contact and the first piece of equipment that they purchase and carry with them.

The vocal quality is of paramount importance in most sung music, and the easiest way to improve it is often to change vocal mics.

Dynamic mics use the same principle as a loudspeaker, except in reverse. A diaphragm attached to an induction coil is positioned in a magnetic field. Sound moving the diaphragm creates electromagnetic induction resulting in an electrical current current. The geometry of sound entering the front, sides and rear of the capsule determines its sensitivity to sounds arriving from different angles.

Microphones are described by their pickup pattern.

A microphone equally sensitive to sound from any direction is called omni-directional. This type is less desirable in live sound unless they’re positioned extremely close to the intended sound source and able to favor it to the exclusion of other sounds.

Common examples are miniature lavalier condenser mics used as “body mics” for voice or close contact with acoustic instruments, a subject for a future Real World Gear. An omni-directional mic has equal response to sound from all directions, and its polar plot is a round sphere. [read]
