Abstract
Disclosed is a suspended audio device with bass enhancement performance, including a low-pass filter, a high-pass filter, an energy controller and a harmonic generator. The low-pass filter is configured to extract a low-frequency signal in an original input signal, and input the low-frequency signal as a fundamental wave of the harmonic generator; the high-pass filter is configured to extract a mid-high frequency signal in the original input signal; the harmonic generator is configured to process the low-frequency signal extracted by the low-pass filter through the NLD algorithm, and generate at least one enhanced harmonic signal in the low-frequency signal; the energy controller is configured to control an overall gain of the at least one enhanced harmonic signal generated by the harmonic generator.
