发明名称 Speaker systems with lower frequency of resonance
摘要 Speaker systems with lower frequency of resonance have a short air passage in a cabient from the speakers or drivers to an air passage exit. Teh resulting column of air lowers the resonant frequency or the drivers from within a frequency range of interest to below the frequency range. With the resonance out of the way, the resulting system is smaller and smoother.
