Embodiment Construction

[0019] Exemplary embodiments are now discussed. Other embodiments may also be added or substituted. Details that are obvious or unnecessary are omitted for space saving or more efficient explanation. Conversely, some embodiments may be practiced without all of the details disclosed herein.

[0020] figure 1is a block diagram illustrating one example of a compressor-based bass boost system for enhancing the bass response of a speaker system. The bass boost system 10 includes inputs 12 and 14 configured to receive left and right channel signals, respectively, of an audio stereo program. The left channel input 12 is coupled to an input of LPF (low pass filter) 16 and to an input of HPF1 (high pass filter) 18 . Right channel input 14 is coupled to the input of LPF 20 and the input of HPF 122 . The outputs of both LPFs 16 and 20 are connected to a low-band compressor 24, which is configured to compress each signal and provide compressed signals at respective outputs of the com...

Abstract

A system for and method of enhancing the low frequency response of a loudspeaker for relatively low input level audio signals and protect the loudspeaker for relatively high input level audio signals is disclosed. The system comprises: a crossover network configured so separate an audio input signal into at least two frequency bands including a low frequency band; and a signal compressor responsive to the energy level of the low frequency portion of an input audio signal in the low frequency band and configured to provide amplification gain on the low frequency portion of the input signal when the energy level of the low frequency portion of the input signal is relatively low so as to enhance the low frequency response of the loudspeaker, and attenuation of the low frequency portion of the input signal when the energy level of the low frequency portion of the input signal is relatively high so as to protect the loudspeaker from being overdriven. The system is configurable so that it can be used to enhance the loudspeakers of audio and video play devices such as televisions and computers.
