Description

к входам первого усилител  6, выходы которого подключены к выходным шинам 7. Выходы первого усилител  6 подключены к входам второго усилител  8. выходы которого соединены электрически с обмотками 5.to the inputs of the first amplifier 6, the outputs of which are connected to the output buses 7. The outputs of the first amplifier 6 are connected to the inputs of the second amplifier 8. whose outputs are electrically connected to the windings 5.

Электропровод щие П-образные магнитные сердечники 4 укреплены в корпусе 9 посредством изолирующих элементов (на чертеже не изображены), а электропровод щий квадратный стержневой посто нный магнит 3 установлен на дополнительном посто нном магните 10 посредством гибкой изолирующей втулки 11.Electrically conductive U-shaped magnetic cores 4 are fixed in housing 9 by means of insulating elements (not shown), and electrically conducting square rod permanent magnet 3 is mounted on an additional permanent magnet 10 by means of flexible insulating sleeve 11.

Колебани  иглы 1 с помощью емкоСтного преобразовател , образованного гран ми электропровод щего квадратного стержневого посто нного магнита 3 и торцами электропровод щих П-образных магнитных сердечников , привод т к формированию на выходах первого усилител  6 напр жени , пропорционального изменени м во времени рельефа канавки стереофонической пластинки . Это напр жение поступает на выходные щины 7, а также подаетс  через второй усилитель 8 в обмотки 5, что обеспечивает компенсацию инерции подвижной системы и уменьщение нелинейных искажений результата воспроизведени  со стереофонической грампластинки.The oscillations of the needle 1 using a capacitive transducer formed by the edges of an electrically conductive square rod constant magnet 3 and the ends of electrically conductive U-shaped magnetic cores result in the formation of a voltage at the outputs of the first amplifier 6 proportional to changes in time of the grooved relief . This voltage is supplied to the output lines 7, and is also fed through the second amplifier 8 to the windings 5, which compensates for the inertia of the moving system and reduces the non-linear distortion of the playback result from the stereophical record.

Использование изобретени  позволит уменьщить нелинейные искажени  результата воспроизведени  со стереофонической грампластинки. Подобное устройство может найти применение в стереофонических электрофонах .The use of the invention will reduce non-linear distortion of the result of reproduction from a stereophonic record. Such a device can be used in stereo electrophones.
