ABSTRACT:
A microphone device includes a base adapted to be installed in a given position, an arm mounted on the base for angular movement in a predetermined angular range with respect thereto, and a sound pickup unit mounted on a distal end of the arm for picking up sounds when the arm is angularly positioned at a predetermined angle with respect to the arm. The base may be installed on a pillar positioned obliquely in front of the driver's seat of a motor vehicle, so that the microphone can be held in a good position with respect to the driver. The microphone is positioned in superposed relation or in the vicinity of the pillar that is present in the front vision of the driver on the driver's seat, and hence does not essentially interfere with the front vision of the driver.
