PURPOSE:To provide a microphone which can be adapted to the acoustic equipments of a double channel transmission system, can express the right-left and front-rear directions, and can collect the sounds. CONSTITUTION:A microphone can obtain the sound signals with the sound collecting elements 3L, 3R and 3S corresponding to the L, R and rear channels respectively. At the same time, the microphone mixes the rear sound signals SS1 and SS2 of two system having the phases opposite to each other with the L and R channels respectively through an encoder 2. Thus both rear sound signals are turned into the channels Lt and Rt and outputted. In such a constitution, the microphone can be applied to the acoustic equipments of a double channel transmission system. |
