Електродинамичният високоговорител, като комплексен товар на аудио усилвателя

Abstract

It is known that the professional audio amplifiers operate with dynamic input signal. Output speaker connected to the amplifier is a complex load with pronounced resonant properties. This can cause overloading of the output stage and unstable amplifier. In some cases their inductance of the speaker can suppress transient loads and even prevent breakthrough. For accurate assessment of the impact of the complex load on the amplifier performance should be considered the equivalent resonance model.
