Description
Известны двухканальные стереофонические звуковоспроизвод щие устройства, содержащие два громкоговорител (или грунпу громкоговорителей ), подключенные к соответствующ.им усилител м с регулируемым при помощи управл ющего сигнала коэффициентом усилени , входы которых соединены с источником воспроизводимого сигнала, представл ющего комбинацию сигналов, полученных от двух наиравленных микрофоно, расположенных под углом 45 один относительно дру гого. Подобные устройства не обеспечивают получени высококачественного стереофонического звучани .Two-channel stereophonic sound reproducing devices are known, which contain two loudspeakers (or loudspeakers), connected to corresponding amplifiers with a gain-adjustable control signal, whose inputs are connected to a source of reproduced signal representing a combination of signals received from microphone, located at an angle of 45 one relatively different. Such devices do not provide high-quality stereo sound.
В описываемом устройстве этот недостаток устранен при:,1енение, усилителей с линейной зависимостью коэффициента усилени от частоты с выходными фазорзсщенительными каскадами, соединенными с выпр мител ми , выдел ющими огибающие усиливаемых сигналов.In the device described, this disadvantage is eliminated with:, the generation of amplifiers with a linear dependence of the gain on the frequency with output phase-locking cascades connected to rectifiers selecting the envelopes of the amplified signals.
Два направленных микрофона / и 2 (см. блок-схему) установлены так, что их оси максимальной чувствительности образуют угол в горизонтальной плоскости- Сигналы на выходе микрофонов 1 н 2 усиливаютс соответственно микрофонными усилител ми 3 и 4 и поступают на блоки 5 и 6 управлени модул цией и громкостью, вход щие в состав этих усилителей. Сигналы с выхода блоков 5 и 6 управлени после усилителей 7 и S с регулируемым коэффициентом усилени суммируютс The two directional microphones / and 2 (see block diagram) are set so that their axes of maximum sensitivity form an angle in the horizontal plane. modulation and volume included in these amplifiers. The output signals from blocks 5 and 6 of the control after amplifiers 7 and S with adjustable gain are summed
