Divider and speaker unit?
Because almost all of the speakers now use more cell division band replay of design patterns, so you must have a device capable of power broadcasting to the whole band music signals as needed into the treble, bass or treble, Alto, bass, to keep the appropriate driver to connect, the divider is a device. If you put the whole frequency band signal not assigned directly into the high, mid, bass unit, in addition to the frequency response range of the section "extra signal" on normal in-band signals has a negative impact on the reduction or even make the treble, Alto cell damage. From the circuit structure, the divider is essentially by the capacitor and the inductor coil form of LC filter network, treble channel is high-pass filter, it only allows high-frequency signal through and stop this low-frequency bass channel signal; just think back, it only makes bass through this high-frequency signal which resistance; audio channel is a bandpass filter, in addition to a low a high two crossover point between frequency can, high-frequency components and low frequency components will be blocked. In the actual divider, sometimes in order to balance high, bass unit sensitivity disparity between, also joined the decay resistance; in addition, some divider also joined by the resistance, capacitance compensation network consisting of impedance, and its purpose is to enable speaker impedance curve some psychological flat so that the power amplifier driven.
