摘要： A centrifugal-type blower includes a shaft, a fan, and a casing. The casing includes an inlet, an air passage, and a side wall part. A first distance from a center of the fan to the wall part at an inlet side end portion in a radial direction of the fan gradually increases from a volute start part to a volute end part. A second distance from the center to the wall part at any position thereof from an intermediate position to a counter-inlet side end portion in the radial direction is larger than the first distance within a first range. The second distance gradually decreases from the volute start part to a predetermined position. The second distance has the same length as the first distance within a second range.

摘要： An air-outlet mode selecting device includes first and second rotary doors. Each of the first and second rotary doors has rotary shafts separated from each other in an axial direction of the rotary shafts, an outer peripheral door surface that is provided at a position separated radial outward from the center line of the rotary shafts and is turned with the rotary shafts, and left and right side plates for connecting both ends in the axial direction of the outer peripheral surface and the rotary shafts. One of the first and second rotary doors opens and closes a specified opening among three openings and other rotary door opens and closes the remaining two openings among the three openings. Accordingly, door operation force and air flow resistance can be effectively reduced, and the size of the air-outlet mode selecting device can be effectively reduced.

摘要： Obtaining a satisfactory feeling of mounting an earphone regardless of the user and achieving listening to reproduced acoustics with satisfactory sound quality is provided by an elastic auricle-mounting member surrounding a sound-discharging opening formed on a housing that accommodates a speaker unit. A space formed by the eardrum membrane, the speaker unit and the auricle-mounting member when a user wears the earphone on the auricle is communicated to the outside of the earphone via a ventilation resistor. Thus, it is possible to prevent deterioration in the sound quality attributable to pooled indistinct sound generated when the space encircled by the eardrum membrane, the speaker unit and the auricle-mounting member has been sealed.
