The electroacoustic device which possesses the call signal occurrence expedient which can make subjective bass perceive

摘要

The electronic acoustic device (1) to have, possess the call signal (CS) the call signal occurrence expedient which occurs (20) the call signal (CS) the electronic acoustic transmitter which is played back (9), call signal occurrence expedient (20), specified frequency (f1 and f2. .fn) fundamental tone signal (GS1 and GS2. As .GSn) occurred, at least two which conforms respectively fundamental tone signal occurrence steps (GT1 and GT2. .GTn) to possess, in order aforementioned call signal occurrence expedient (20), control to drive the aforementioned fundamental tone signal occurrence expedient unrestrictedly, the control means which operate (21) possess, with those control means, the fundamental tone signal occurrence step (GT1 and GT2. .GTn), is driven at specified time interval, the aforementioned fundamental tone signal occurrence expedient (20), the frequency which is rational ratio mutually (f1 and f2. As .fn) generated the fundamental tone signal, to conform, the aforementioned control means, at least within specified time interval two fundamental tone signal occurrence steps (GT1 and GT2. .GTn) it drives simultaneously.
