Abstract
Apparatus for making stereophonic recordings using multiple microphones, and playing back the recordings through multiple speakers, wherein each of the microphones is mounted with a corresponding speaker in a single enclosure. For convenience, the microphones and speakers may be connected by flexible leads to a separate record-playback unit, and, since each microphone is permanently located immediately adjacent a corresponding speaker, the apparatus is capable of accurately reproducing the recorded sounds in their apparent locations by providing the same stereophonic separation for recording as for playback.
Claims7
Portable stereophonic recording and playback apparatus, comprising:
- a plurality of microphones for transducing acoustical energy in a sound field into electrical signals in a like plurality of discrete channels;
- electrical means connectable with said plurality of microphones and selectively operable in a record mode to record said electrical signals onto a recording medium, and subsequently in a playback mode to reproduce the electrical signals from the recording medium;
- a housing for said electrical means;
- a like plurality of speakers, connectable with said electrical means in the playback mode, for transducing said reproduced electrical signals into acoustical energy, thereby to reproduce the sound field;
- a like plurality of independently movable speaker-microphone enclosures, each enclosing one of said speakers and one of said microphones, to provide equal stereophonic separation for both the record and playback modes;
- and
- a plurality of connecting cables for connecting each of said speaker-microphone enclosures with said electrical means, whereby each of said speaker-microphone enclosures requires only one of said connecting cables to connect both its speaker and its microphone to said electrical means.
