Description

Предлагаемое изобретение относитс  к устройствам дл  радиоприема без антенн и рамок и имеет целью упростить существующие схемы дл  радиоприема при сохранении обычной слышимости и повышении остроты настройки. В предлагаемом устройстве дл  воспри ти  энергии электромагнитных волн, вместо антенны, служат две :оаксиа.)уьно расположенные катушки переменной самоиндукции, св занные между собой магнитным потоком и присоединенные к детектору или входному контуру усилител .The present invention relates to devices for radio reception without antennas and frames and is intended to simplify existing schemes for radio reception while maintaining normal audibility and increasing the sharpness of tuning. In the proposed device, for receiving the energy of electromagnetic waves, instead of an antenna, there are two: oaxia.) Uninstalled coils of variable self-induction, interconnected by a magnetic flux and connected to the detector or input circuit of the amplifier.

На чертеже фиг. 1 изображает схему предлагаемого устройства; фиг. 2 и 3-видоизменени  указанной схемы.In FIG. 1 depicts the scheme of the proposed device; FIG. 2 and 3, a modified scheme.

Согласно изобретению катушки I и II (фиг. 1) располагаютс  коаксиально ,при чем начальный конец катушки I соединен с ползунком катушки II, а ползунок катушки I и конец катушки II св заны соответственно с клеммами, между которыми приключен входной контур усилител . На фиг. 2 применена дл  усилени  эффекта приема катушка III обратной св зи. На фиг. 3-такие же, как и выше, катушки I и II присоединены не к усилительному контуру, а непосредственно к детекторуч: телефоном.According to the invention, coils I and II (Fig. 1) are arranged coaxially, the initial end of coil I is connected to the slider of coil II, and the slider of coil I and the end of coil II are connected respectively to the terminals between which the input circuit of the amplifier is adventitious. FIG. 2 is applied to enhance the reception effect of coil III feedback. FIG. 3- the same as above, coils I and II are not connected to the amplifying circuit, but directly to the detector: a telephone.

Предмет патента.The subject of the patent.
