Abstract
A condenser microphone having a capsule with a cardioid pattern diaphragm on opposite sides of a back plate wherein each diaphragm is selectively activated via a switch to complete the audio circuit. The microphone employs two different diaphragm materials to produce two different sound reproduction characteristics. A first diaphragm produces a “warm and lush” sound output, while the second diaphragm produces a “bright and airy” sound output. The microphone includes the use of a pair of light emitting diodes located behind the grill indicating which capsule diaphragm is activated. The dual diaphragm arrangement is mounted on a standard microphone body and includes conventional electronics for connection to an associated piece of audio equipment producing phantom power.
Claims20
A condenser microphone providing different sound reproduction characteristics, comprising:
- a body;
- a capsule assembly extending from said body including a back plate with a first side and a second opposite side with a cardioid pattern diaphragm on each side thereof, wherein the diaphragm on the first side is made from a material having different reflective properties than the diaphragm on the second side;
- and
- a switch mounted to the body to selectively activate one of said diaphragms independent of the other to produce a microphone with two different sound reproduction characteristics.
A condenser microphone providing different sound reproduction characteristics, comprising:
- a body;
- a capsule assembly extending from said body wherein the capsule includes a back plate with a first side spaced from a first cardioid pattern diaphragm and a second side spaced from a second cardioid pattern diaphragm of a different thickness than the first diaphragm;
- and
- a switch mounted to the body to selectively activate one of said diaphragms independent of the others to produce a microphone with two different sound reproduction characteristics.
