Abstract: A microphone device includes: a housing having an opening section in an upper face thereof; and a non-directional microphone unit incorporated in the housing and provided inside the opening section. The upper face of the housing has a shape in which a distance from an edge defined as a boundary between the upper face and a side face or a bottom face to the opening section throughout a whole circumference of the upper face changes in ½ or more of the whole circumference of the edge and an average value of the distance from the edge to the opening section is shorter than ½ of a wavelength of a sound wave in a frequency range in which an auditory sensitivity of humans is low.

Abstract: An audio-video apparatus, which is connectable to a plurality of external devices (e.g., DVD players, TV monitors, and game devices) so as to process input signals thereof and to thereby control them individually, stores a plurality of packaged information regarding setups and operations, i.e., a plurality of scene templates, which are assigned to a plurality of scene buttons in advance. When the user presses a desired scene button, the corresponding scene template is called and read out so as to automatically realize prescribed setup and operation in connection with a desired external device. The audio-video apparatus allows the user to edit and customize scene templates assigned to the scene buttons in association with messages indicating details of scene templates, which are visually displayed on the screen.
