Method and apparatus for audio bass enhancement using stereo speakers

摘要

Provided are a method and apparatus for audio bass enhancement using stereo speakers. By filtering a baseband signal of an input signal whose frequency is lower than a blocking frequency calculated based on the distance between first and second speakers, delaying the filtered signal for a predetermined time period, combining a signal component of the input signal output from the first speaker and a signal component of the delayed signal output from the first speaker and making the combined signal component correspond to the first speaker, and combining a signal component of the input signal output from the second speaker and a signal component of the delayed signal output from the second speaker and making the combined signal component correspond to the second speaker, deep and rich audio bass can be provided by a simple operation without structural modification of speakers with respect to micro speakers in which audio bass reproduction is not conventionally performed efficiently.
