Abstract

A microphone system includes a portable frame for mounting linear pick-up microphones such that each of the microphones has its diaphragm facing outwards from the frame and the diaphragms form a generally elliptical pattern. A microphone with a substantially hemispherical pick-up pattern is mounted on the frame such that it is directed upwards and a second substantially hemispherical pick-up pattern microphone is mounted on the frame directed downwards. The linear pick-up pattern microphones are equispaced about the perimeter of the frame. There is a hand or camera grip depending downwards from the frame. The microphones of the frame can be electronically connected to the respective channels of a multi-channel sound system, or to the channels of a multi-channel digital mixer which in turn can be connected to a multi-channel sound recording device. The microphones may be selectively electronically connected and disconnected to adapt the system for a predetermined sound playback configuration.

Dependent claims

A multi-channel sound reproduction system comprising:

a multi-channel microphone array including:
a plurality of linear pick-up pattern microphones, each having a diaphragm;
at least one hemispherical pick-up pattern microphone having a substantially hemispherical pick-up pattern;
and
a portable frame having:
means for mounting said plurality of said linear microphones with diaphragms forming a generally elliptical non-circular microphone arrangement pattern, each diaphragm facing outwards from the frame directing an associated linear pick-up pattern at a predetermined polar orientation;
and means for mounting the hemispherical microphone within said elliptical pattern;
multi-channel mixer with means for individually connecting each said linear microphone to a corresponding individual channel;
a multi-channel sound recording device each channel thereof communicating with a corresponding channel of the mixer;
and
a multi-channel playback system including:
a plurality of playback speakers, each speaker having means for communicating with an individual channel of the recording device and having an auditory playback pattern directed towards a stationary listener position, the polar orientation of each playback pattern corresponding with the polar orientation of the associated linear microphone communicating with the associated individual channel.
