Abstract
PURPOSE:To realize a sound field with high reality even in a small space by constituting a device so that an input signal is band-divided and the levels of VCAs(voltage controlled amplifier) of high-pass and low-pass connected to a speaker, respectively and their change speed can be controlled independently. CONSTITUTION:The band area of the input signal is divided into a low-pass area and a high-pass area by a low-pass filter 1 and a high-pass filter 2. Next, the levels of the VCAs 3-10 connected to the speaker, respectively and their change speed are controlled by a control means 19 in the low-pass area and the high-pass area, independently. Furthermore, the output of the VCA3 of low-pass component and the output from the VCA7 of high-pass component are added, and it is reproduced from the speaker 15 via an amplifier 11. After the same control are applied on the VCAs 4-6 and the VCAs 8-10 by the control means 19 with the same method, they are added, and are reproduced from the speakers 16-18. As a control method for the VCAs 3-10, the levels of the VCAs 3-6 and the VCAs 7-10 and the change speed of the levels are controlled independently and at random in case of requesting to generate the sound field with reality.
