Abstract
A dual diaphragm dynamic type microphone transducer that, among other things, provides control of source/receiver proximity effects without sacrificing professional level dynamic microphone performance.
Claims22
A dual diaphragm microphone transducer comprising:
- a housing;
- and
- a transducer assembly supported within the housing to accept acoustic waves, the transducer assembly comprising:
- a magnet assembly;
- a front diaphragm disposed adjacent the magnet assembly and having a front and rear surface, the front surface configured to have acoustic waves impinge thereon, the rear surface having a coil connected thereto such that the coil is capable of interacting with a magnetic field of the magnet assembly;
- and
- a rear diaphragm having a front and a rear surface, the rear surface opposingly disposed adjacent the magnet assembly with respect to the rear surface of the front diaphragm, the front surface configured to have acoustic waves impinge thereon;
- the transducer assembly defining an internal acoustic space;
- the housing having at least one air passage establishing acoustic communication between the internal acoustic space and a cavity within the housing, wherein the cavity is situated adjacent to the front surface of the rear diaphragm.

A dual diaphragm microphone transducer comprising:
- a housing having a resonator with at least one aperture to allow acoustic waves from a sound source to pass therethrough;
- and
- a transducer assembly supported within the housing to accept the acoustic waves, the transducer assembly comprising:
- a magnet assembly;
- a front diaphragm disposed adjacent the magnet assembly and having a front and rear surface, the front surface disposed adjacent the resonator of the housing, the rear surface having a coil connected thereto such that the coil is capable of interacting with a magnetic field of the magnet assembly;
- and
- a rear diaphragm having a front and a rear surface, the rear surface disposed adjacent to and facing the magnet assembly;
- the housing having at least one air passage establishing acoustic communication between a space behind the front diaphragm and a cavity in the housing, wherein the cavity is situated adjacent to the front surface of the rear diaphragm.

A dual diaphragm microphone transducer comprising:
- a housing having a front portion and a rear portion, the front portion having a resonator with at least one aperture to allow acoustic waves from a sound source to pass therethrough, the rear portion having a cavity formed therein;
- and
- a transducer assembly supported within the housing to accept the acoustic waves, the transducer assembly comprising:
- a magnet assembly;
- a front diaphragm disposed adjacent the magnet assembly and having a front and rear surface, the front surface disposed adjacent the resonator of the housing, the rear surface having a coil connected thereto such that the coil is capable of interacting with a magnetic field of the magnet assembly;
- and
- a rear diaphragm having a front and a rear surface, the rear surface disposed adjacent to and facing the magnet assembly;
- the housing having at least one air passage establishing acoustic communication between a space behind the front diaphragm and the cavity within the rear portion of the housing, wherein the cavity is situated adjacent to the front surface of the rear diaphragm.
