Description

Предлагаемое изобретение касаетс  устройства дл  лечени  тугдухих звуковыми упражнени ми и состоит в форме выполнени  схемы генератора тока звукрвой° частоты.The present invention relates to a device for the treatment of dull sound exercises and consists in the form of an oscillator current generator circuit.

На чертеже изображена электрическа  .схема устройства. ,The drawing shows an electrical circuit device. ,

Катодный генератор- 1 высокой частоты помещен в переменное магнитное, поле 2, направленное параллельно его нити накала . Это поле создаёт биени  звуковой частоты в анодном контуре 3,4, состо щем из конденсатора переменной емкости 3 и катушки самоиндукции 4, включенных параллельно. Контур 3,4 св зан магнитным потоком с катодным детектором б, а в анодный контур последнего включена обмотка 7 трёхобмоточного -трансформатора 8. Втора  его обмотка 9 служит дл  получени  на зажимах 12 тока звуковой частоты, а треть  короткозамкнута  обмотка 11, подвижна  относительно сердечника 10, предназначена дл  регулировки силы тока звуковой, частоты.The cathode generator-1 high frequency is placed in an alternating magnetic field 2, directed parallel to its filament. This field creates a beating of the audio frequency in the anode circuit 3.4, consisting of a variable capacitor 3 and a self-induction coil 4 connected in parallel. The circuit 3,4 is connected by a magnetic flux with the cathode detector b, and the winding 7 of the three-winding β-transformer 8 is connected to the anode circuit of the latter. The second winding 9 serves to receive an audio frequency at the terminals 12 and a third short-circuited winding 11 moving relative to the core 10 , is designed to adjust the current of the sound frequency.

К за ккмам 13 прикл-ючаетс  плюс, к зажиму 14 -минус источника питани анода, а к зажиму 15-плюс источника питани  потенциометра 16.A terminal 13 is attached plus, terminal 14 is the minus of the anode power source, and terminal 15 is the plus source of the potentiometer 16.

Предмет патента.The subject of the patent.

Устройство дл  лечени  тугоухих, характеризующеес  применением катодного генератора 1 высокой частоты, помещенного в переменное магнитное поле, создаюшее биени  звуковой частоты в анодном контуре 3,4, св занном магнитным потоком с катодным детектором 6, в анодный контур которого включена одна обмотка 7 из обмоток трёхобмоточного трансформатора 8 низкой частоты, от второй обмотки 9 которого беретс  ток звуковой частоты, ,а треть  подвижна  обмотка 11 которого замкнута накоротко и предназначена дл  изменени  силы тока в обгйотке 9.A device for treating hearing aids, characterized by the use of a high-frequency cathodic generator 1 placed in an alternating magnetic field, creates a beating of sound frequency in the anode circuit 3,4, connected by magnetic flux to the cathode detector 6, one winding 7 of three windings is included in the anode circuit of a low-frequency transformer 8 from which the second winding 9 receives an audio frequency current, and the third movable winding 11 of which is short-circuited and is intended to change the current in the hopper 9.
