Abstract:
    This invention relates to a method for controlling audio frequency property of sound devices automatically and accurately including: testing the audio frequency property of a sound device, comparing difference of frequency properties between actual test and target, utilizing an operational control unit and an approaching algorithm to regulate related parameters of driven sound signals till the optimum one to reach the accurate frequency property by regulating electric signals to compensate the frequency property of the sound device, the technological plan includes the following parts: 1, a sound device with 3 units: a data storage unit, a sound driving unit and a sound unit, 2, a surrounding testing and data feed back control part including two units: an audio signal test unit and an operation control part suitable for products of audio dialers, chromatic tuners of pianos, acoustics and radios.
