A DIVIDER OF A HIGH FIDELITY AND UNDISTORTED BAFFLE BOX
Document Type and Number:
WIPO Patent Application WO/2003/047308
Kind Code:
A1
Abstract:
The invention relates to a divider of a high fidelity and undistorted baffle box, is overcomes the shortcomings of electrical phase distortion, bass distortion, unclear bass, audio-visual location indistinct, tone distortion, seriously insufficient of basic bass or super-bass, excessively high median sound in the prior art. Between an input terminal S1 and a common terminal S2, a mid frequency divider circuit having a capacitor C2, an inductor L2 and a resistor R in serial and a basic bass divider circuit having a capacitor C and an inductor L4 in serial are used. The invention can overcome the above shortcomings and it has the advantages of extremely low of lower limit of low frequency, ample super-bass or bass; very ideal form of the characteristic curve of the sound energy, large dynamic range, higher sensitivity and efficiency and inexpensive cost.
