Abstract
A sound pickup device is designed for an imaging apparatus including an objective lens and a camera casing. The sound pickup device includes first and second microphone holders fixed to the camera casing and each having an inner wall surface neighboring and facing a surface of the camera casing. First and second microphone units are held by the first and second microphone holders, respectively. The first and second microphone holders are located at left and right sides of the camera casing respectively while being separated from each other in a direction perpendicular to an optical axis of the objective lens. The aforesaid surface of the camera casing forms a sound reflecting surface which reflects incoming sound. Each of the first and second microphone units has a sound pickup surface facing the sound reflecting surface to pick up the sound reflected by the sound reflecting surface.
