AB  - Methods for picking up quadraphonic sounds have not yet been thoroughly investigated. At present, four unidirectional microphones are being used. It is obvious, however, that some kind of quadraphonic one-point pickup microphone will become necessary in the near future, as it was the case with the stereophonic one-point pickup microphone. A microphone with four diaphragms whose principal axes are perpendicular to each other in a plane is studied by means of equivalent electric circuits of the vibrating system. It is shown that the microphone can be a quadraphonic one-point pickup microphone with four unidirectional patterns. The measured results of experimental quadraphonic capacitor microphones agree well with predicted results from the analysis.
