An audio equipment support include; a main body including a protrusion and being configured to be attachable to an audio equipment housing; a counterpart body including an outer edge and a recess contacting the protrusion, the outer edge of the counterpart body being positioned inward of an outer edge of the main body when viewed from a direction in which the protrusion and the recess are aligned; and a restriction member fixed to the main body and spaced apart from the counterpart body, the restriction member including a through-hole through which the counterpart body passes and being configured to restrict a distance between the main body and the counterpart body from reaching or exceeding a predetermined length.

Audio equipment, and support for audio equipment

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 &#xbd; 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 &#xbd; of a wavelength of a sound wave in a frequency range in which an auditory sensitivity of humans is low.

Microphone device

An electronic apparatus is housed in a dual housing structure that includes an inner case housing electronics and an outer case surrounding the inner case. The inner and outer cases have respective intake openings and are spaced from each other by a sufficient distance such that an intake chamber is defined therebetween. A fan unit is provided, for discharging exhaust air from within the apparatus, and a silencer is provided, for silencing the exhaust air discharged via the fan unit. Mounting portions are formed on the front and rear surfaces of the fan unit and are attached to a fan case via gel-state shock absorbers.

Ventilating structure and mounting structure for electronic apparatus

Electronic apparatus is housed in a dual housing structure that includes an inner case housing electronics and an outer case surrounding the inner case. The inner and outer cases have respective intake openings, and in the area where the respective intake openings are provided, the inner and outer cases are spaced from each other by a sufficient distance such that an intake chamber is defined between the inner and outer cases. The intake opening of the inner case and the intake opening of the outer case are displaced from each other with respect to a front-and-rear direction of the apparatus so as to provide a nonlinear intake passage.
