    摘要: An audio apparatus includes an electronic graphic equalizer, in which a plurality of frequency characteristics corresponding to various space configurations are stored preliminarily and a plurality of frequency characteristics corresponding to various types of music are also stored preliminarily. Suitable frequency characteristics are selected from these two groups of frequency characteristics according to a specific spatial configuration and a specific music to be reproduced and combined to obtain a frequency characteristics suitable for the configuration and the music.

    摘要: A suspension for disk drive, comprising a load beam having a proximal end portion fitted with a base plate, a distal end portion fitted with a flexure, and bent edges formed individually on the opposite sides thereof, the load beam being gradually tapered from the proximal end portion toward the distal end portion, a support projection interposed between the load beam and the flexure, and a flexible portion of the load beam defined in a region between the support projection and the base plate. Openings are formed in an inner portion of a second region between the center of gravity of the flexible portion and the base plate, inside the bent edges, so that K.sub.Lb /K.sub.SP is 2 or more, where K.sub.Lb is a spring constant for a first region between the center of gravity of the flexible portion and the support projection and K.sub.SP is a spring constant for the second region, the area of the openings accounting for 25% or more of the area of the inner portion.
