Ultra-low frequency sound compensation method and system based on haptic feedback, and computer-readable storage medium

A haptic feedback-based ultra-low frequency sound compensation method applied to an ultra-low frequency sound compensation system, the ultra-low frequency sound compensation system comprising a response module, a processing module and a vibrator, and the haptic feedback-based ultra-low frequency sound compensation method comprising:

• sensing, by the response module, an ultra-low frequency sound compensation operation of a user;
• and outputting, by the response module, a control command when sensing the ultra-low frequency sound compensation operation;
• the response module includes a phone content interface and a control command unit:
• an ultra-low frequency sound compensation button is set on the phone content interface through a floating manner;
• the ultra-low frequency sound compensation operation is that users can touch the ultra-low frequency sound compensation button to start or stop the ultra-low frequency sound compensation function, and slide the ultra-low frequency sound compensation button to adjust the ultra-low frequency sound compensation intensity;
• After the user touches the ultra-low frequency sound compensation button, the control command unit will generate a corresponding control command and transmit the control command to the processing module;
• processing, by the processing module, an audio signal to be output under control of the control command to obtain an ultra-low frequency signal from the audio signal to be output;
• the processing module comprises a preprocessing unit, a processing chip and a power amplifier;
• and
• the step of “processing, by the processing module, an audio signal to be output under control of the control command to obtain an ultra-low frequency signal from the audio signal to be output” comprises:
• identifying and extracting, by the preprocessing unit, a target signal of a preset type from the audio signal to be output under the control of the control command as the ultra-low frequency signal;
• obtaining by the processing chip, the ultra-low frequency signal from the preprocessing unit;
• and
• amplifying and transmitting, by the power amplifier, the ultra-low frequency signal from the processing chip to the vibrator;
• and
• generating, by the vibrator, a vibration under drive of the ultra-low frequency signal.
