the parameter generating unit is used for acquiring at least one hardware parameter of the audio output unit; determining an audio playing parameter based on the at least one hardware parameter according to a preset rule, wherein the audio playing parameter represents a corresponding relation between a diaphragm displacement and temperature of a loudspeaker of the audio output unit;
the information processing unit is used for acquiring a first instruction and determining a first multimedia file according to the first instruction;
and the audio output unit is used for controlling the audio output unit to play the first multimedia file according to the audio playing parameter.
7. The electronic device of claim 6, wherein the hardware parameters comprise: the maximum displacement of a diaphragm of a loudspeaker of the electronic equipment audio output unit, and/or the maximum power, and/or the corresponding relation between the power and the temperature.
8. The electronic device of claim 6, further comprising:
the first detection unit is used for acquiring a first diaphragm displacement of a loudspeaker of the audio output unit; determining a first temperature corresponding to a loudspeaker of the audio output unit according to the first diaphragm displacement and the audio playing parameter; and when the first temperature is higher than a preset threshold value, adjusting the output power of the audio output unit to reduce the output power of the audio output unit by a preset value.
9. The electronic device of any of claims 6-8, further comprising:
the second detection unit is used for acquiring the first diaphragm displacement of the loudspeaker of the audio output unit; judging whether the displacement of the first diaphragm is larger than a preset displacement threshold value or not; and when the displacement is larger than the displacement threshold, adjusting the output power of the audio output unit to reduce the output power of the audio output unit by a preset value.
10. The electronic device of claim 9, further comprising:
the parameter storage unit is used for storing one or more preset equalizer parameters;
correspondingly, the information processing unit is further configured to adjust the output power of the frequency band corresponding to the audio output unit according to the selected equalizer parameter.
