Description
Насто щее изобретение касаетс схемы включени телефонного аппарата с цен тральной батареей в линию последовательно с обмоткой трансформатора с целью усилени исход щей от аппарата энергии телефонного тока,The present invention relates to a circuit for switching a telephone set with a central battery in a line in series with a transformer winding in order to amplify the energy of the telephone current coming from the apparatus,
С этой целью, микрофон М включен в линию последовательно с обмоткой 1-1 трансформатора Т, микрофон же шунтирован цепью из конденсатора C телефона Т и обмотки 2-2 трансформатора Тр. При разговоре на линию идет не только освобождающа с энерги микрофона, но и энерги зар дноразр дных токов конденсатора С через трансформатор Тр.To this end, the microphone M is connected to the line in series with the winding 1-1 of the transformer T, while the microphone is shunted by a circuit from the capacitor C of the phone T and the winding 2-2 of the transformer Tr. When talking, the line goes not only to the microphone with the energy of the microphone, but also the charge energy of the charge-carrying current of the capacitor C through the transformer Tr.
