DESCRIPTION JPH1169479 [0001] This is an improvement of the network method of the multi-way speaker system, in which a network (filter) is inserted with a low gain amplifier between itself and the speaker unit. In the conventional network system, a filter is inserted between the amplifier and the speaker unit. Due to the relationship between the impedance of the filter and the impedance of the speaker unit that changes with the signal, both theoretical and auditory distortions occur. Another multi-way speaker system is a multi-amplifier system using a channel divider. This method is a. Channel dividers are prone to sound degradation. ロ. Channel dividers with low sound quality degradation and excellent filter characteristics are expensive. ハ. Since a power amplifier having a voltage amplification degree is directly connected to the tweeter unit, a bass voltage is added to the tweeter unit and the tweeter unit is often damaged. ニ. Adjustment on sound quality is delicate. ホ. The cost is high because a normal power amplifier is used. In order to remove distortion of the network system, an amplifier is inserted between the network system and the speaker unit. This amplifier does not require voltage amplification. As the coil, capacitor and load resistor values of the network of the present invention become irrelevant to the impedance of the speaker unit, the set values become much freer, resulting in small size, light weight and cost reduction. Since the load resistance is pure, the filter characteristics are good. The disadvantages of the multi-amplifier scheme using channel dividers do not occur in the present invention. The present invention does not introduce new disadvantages.
