METHOD FOR IMPROVING ACOUSTIC IMAGE OF ELECTRONIC APPARATUS FOR AMUSEMENT AND CIRCUIT THEREFOR

摘要

PROBLEM TO BE SOLVED: To improve the acoustic image of electronic apparatus for amusement by changing audio input signals by stored data and changing audio output signals. SOLUTION: An IF component of sounds arrives at an integrated circuit IC. A control signal is supplied via I2C bus from a microprocessorμP and the audio signal is supplied from, for example, a SCART jack via an AF input side to the integrated circuit IC. The integrated circuit IC is connected to an equalizer EQUA or has an equalizer function. The audio signals I, r are supplied from the integrated circuit via corresponding amplifier circuits Vl, vr to corresponding speakers 1l, lr. The acoustic characteristic data intrinsic to a casing arrives at the microprocessorμP from a unit PRO during production. The audio input signals are thus so changed that the signal characteristics of the audio output signals change in accordance with the stored data.
