Electronic device and equalizer adjustment method thereof for adjusting gain settings of an equalizer according to the volume of the output signal

An equalizer adjustment method for adjusting gain settings of an equalizer according to a volume of an output signal, applied to an electronic device, the electronic device comprising the equalizer, a gain value setting module, a storage module, and an equalizer adjustment module, the equalizer adjustment method for adjusting gain settings of the equalizer according to the volume of the output signal comprising the following steps:

• setting a volume gain value table through the gain value setting module, the volume gain value table comprising a plurality of volume values, which are a first volume value to an Nth volume value, the volume incrementally increasing from the first volume value to the Nth volume value, each of the plurality of volume values comprising a set of correction parameters, the set of correction parameters comprising a plurality of compensation gain values corresponding to a plurality of target frequencies, respectively;
• wherein when the lower the volume value is, the more the volume of the sound at a low frequency is increased and the more the volume of the sound at a high frequency is decreased;
• storing the volume gain value table in the storage module;
• obtaining the volume of the output signal;
• loading the volume gain value table according to the volume of the output signal to obtain the corresponding set of correction parameters;
• and
• adjusting gain value settings of the equalizer for different frequencies of sound according to the set of correction parameters through the equalizer adjustment module.
