Description

Изобретение относитс  к способу многократной записи и воспроизведени  звука, аналогичному способу многократной радиопередачи.The invention relates to a method of multiple recording and reproducing sound, similar to the method of multiple radio transmission.

На приложенном чертеже фиг. 1 изображает схему соединени  приборов дл  многократной записи звука; фиг. 2-схему воспроизведени  звука по этой записи.In the attached drawing of FIG. 1 shows a connection diagram of instruments for multiple sound recording; FIG. 2 is a sound reproduction scheme for this recording.

При записи нескольких звуковых частот на одну и ту же звуковую дорожку на пленке, например, трех можно поступать следующим образом. При помощи трех генераторов высокой частоты получают колебани  различной частоты, например 10, 20 и 30 тыс ч герц, т.е. неслыщимые ухом (фиг. 1). На эти колебани  накладывают колебани  звуковой частоты, которые требуетс  записать. Все генераторы соединены параллельно, и эти суммарные колебани  записывают одним из известных способов записи звука, например Способом Тагера. Про вив пленку, получают некоторую фонограмму , дл  воспроизведени  которойWhen recording multiple sound frequencies on the same soundtrack on a tape, for example, three, you can proceed as follows. With the help of three high-frequency generators, oscillations of various frequencies are obtained, for example, 10, 20, and 30 thousand hertz, i.e. unstable ear (Fig. 1). These vibrations are superimposed on the audio frequency oscillations that need to be recorded. All generators are connected in parallel, and these total oscillations are recorded by one of the known sound recording methods, for example, Tager Method. Having made a film, they get some phonogram, for reproduction of which

пропускают ее в обычном звуковоспроизвод щем аппарате, но на входе второй усилительной лампы (после фотоэлемента) следует поставить детектор, который будет детектировать колебани  высокой частоты, причем контур детектора должен быть настроен на одну из высоких частот в 10, 20 и 30 тыс ч герц, по желанию . При таком способе записи получают большую экономию пленйи.It is passed in a conventional sound-reproducing apparatus, but a detector should be placed at the input of the second amplifying lamp (after the photocell), which will detect high-frequency oscillations, and the detector circuit should be tuned to one of the highest frequencies at 10, 20 and 30 thousand hertz, optional . With this recording method, a great saving of plenium is obtained.

Предмет изобретени Subject invention

Способ многократной записи и воспроизведени  звука с применением светового модул тора, отличающийс  тем, что при записи звука токи нескольких генераторов различных высоких частот, модулированных звуковыми частотами, присоедин ют параллельно к световому модул тору, а дл  воспроизведени  каждой отдельной записи звука примен ют фильтры, соответствующие высоким частотам при многократной записи звука.A method of multiple recording and reproduction of sound using a light modulator, characterized in that when recording sound, the currents of several generators of different high frequencies modulated by sound frequencies are connected in parallel to the light modulator, and filters are used to reproduce each individual sound recording. high frequencies with multiple sound recordings.
