Somatosensory vibration generating device and method for forming somatosensory vibration

A method for forming somatosensory vibration comprising steps of:

• using an audio signal receiving module to receive sound waves from an external environment to generate a first audio frequency signal and transmitting the first audio frequency signal to a digital-to-analog conversion module;
• performing digital-to-analog conversion on the first audio frequency signal with the digital-to-analog conversion module to generate a second audio frequency signal after digital-to-analog conversion, and outputting the second audio frequency signal to a digital signal processing module;
• converting the second audio frequency signal into a first vibration signal through the digital signal processing module, and outputting the first audio frequency signal to an operational amplifier;
• performing gain processing on the first vibration signal through the operational amplifier to obtain a second vibration signal after gain processing, and transmitting the second vibration signal to a tactile transducer;
• and
• the tactile transducer generating a somatosensory vibration in synchronization with external environmental sounds according to the received second vibration signal;
• wherein
• the digital signal processing module optimizes the first audio frequency signal by Fourier series arithmetic processing to remove harmonics and strengthen dominant wave gain;
• a frequency of the second audio frequency signal is less than 200 Hz.
