Description

первую и вторую обмотки 3 и 4 звуковой катушки, датчик 5 сигнала обратной св зи , схему 6 сравнени , корректирующий усилитель 7 и дополнительный усилитель S.the first and second windings 3 and 4 of the voice coil, the feedback signal sensor 5, the comparison circuit 6, the correction amplifier 7 and the additional amplifier S.

Основной усилитель 1, на вход которого ностунает входной сигнал, соединен с нервой обмоткой 3 звуковой катушки громкоговорител  2. На подвижной части громкоговорител  установлен датчик 5 сигнала обратной св зи. Выход датчика соединен с входом схемы 6 сравнени , второй вход которой через корректирующий усилитель 7 соединен со входом (неинвертир)аощим/ основного усилител  1. Выход схемы сравнени  соединен со входом дополнительного усилител  8, выход которого подключен ко второй обмотке 4 звуковой катущки громкоговорител  2.The main amplifier 1, to the input of which there is no input signal, is connected to the nerve winding 3 of the voice coil of the loudspeaker 2. A feedback signal sensor 5 is installed on the moving part of the loudspeaker. The sensor output is connected to the input of the comparison circuit 6, the second input of which is connected to the input (non-inverter) of the primary / main amplifier 1 through the correction amplifier 7. The output of the comparison circuit is connected to the input of the additional amplifier 8, the output of which is connected to the second winding 4 of the sound coil of the loudspeaker 2.

Входной сигнал поступает на основной усилитель, зсиливаетс  и подаетс  в нагрузку , которой  вл етс  перва  обмотка 3. С датчика 5 сигнал обратной св зи снимаетс  напр жение, содержащее искажени , вносимые громкоговорителем и основным усилителем, и подаетс  на вход схемы сравнени , на другой вход которой поступает напр жение входного сигнала через корректирующий усилитель 7. Разность этих сигналов с выхода схемы сравнени  6 поступает на дополнительный усилитель, где усиливаетс  и подаетс  в нагрузку, которой  вл етс  втора  обмотка 4. При этомThe input signal is fed to the main amplifier, compressed and supplied to the load, which is the first winding 3. From the sensor 5, the feedback signal is removed, the voltage containing the distortions introduced by the loudspeaker and the main amplifier, and fed to the input of the comparison circuit, to another input the input voltage is fed through the correction amplifier 7. The difference of these signals from the output of the comparison circuit 6 is fed to an additional amplifier, where it is amplified and supplied to the load, which is the second winding 4. Pr and this

компенсаци  искажений, вносимых громкоговорителем и основным усилителем, происходит в громкоговорителе. Повышение катества звуковоспроизведени  и устойчивости работы устройства происходит за счет исключени  воздействи  сигнала общей обратной св зи на основной усилитель.The loudspeaker and main amplifier distortion compensation occurs in the loudspeaker. The improvement in the catastrophe and the stability of the operation of the device occurs due to the exclusion of the effect of the common feedback signal on the main amplifier.
