ABSTRACT OF THE DISCLOSURE This invention relates to stereophonic micro- phones. In the stereophonic broadcasting and recording of sound, it is necessary to have the sound from the left side separately recorded and reproduced from the sound from the right side. This is often accomplished with spaced microphones, but it is often difficult for the amateur or the hobbiest to position and maintain micro- phones in spaced relationship when he wishes to make a stereo recording. It is often possible to secure a com- parable result if two microphones, both directional, are placed back to back so that each microphone receives sound coming from a different direction. Preferably, the microphones should be separable from each other, so that, when desired, the microphones can be separated and spaced apart so that they may record in the normal stereophonic manner. The present invention comprises a microphone assembly making use of a pair of microphones that are mechanically, but releasably held together. Each of the microphones has similar acoustic and electrical character- istics and each has directivity characteristics such that it responds to sound coming to it from only one side. One form of microphone having such a directivity character- istic is often referred to as a cardioid microphone. The means holding the two microphones together may be of any suitable type, such as a simple mortise and tenon or dove- tail slide.
