Description

Известны уже устройства дл  записи звуков на граммофонной нластинке . состо ище из системы посто нных магнитов, между полюсами которых помещен отделенный от этих П0.1ЮСОВ упругими прокладками, питаемый модулированным током,электромагнит , жестко укрепленный на оси и несущий записывающее острие.Devices for recording sounds on a gramophone nlastinka are already known. It consists of a system of permanent magnets, between the poles of which there is an elastic gasket, separated from these S0.1USOV by elastic gaskets, powered by a modulated current, fixed to the axis and carrying a recording point.

Предлагаемое изобретение касаетс  подобного устройства и состоит в том, что ось, на которой укреплен электромагнит , закреплена неподвижно с той п,елью, чтобы она при действии устройства работала на кручение. The present invention relates to such a device, and consists in the fact that the axis on which the electromagnet is fixed is fixed in place with the support of the device so that it operates in torsion under the action of the device.

На чертеже, схематически изображающем общий вид предлагаемого устройства, на оси а а нодвешена система посто нных магнитов 1, между полюсами которых на оси о о с неподвижно закрепленными концами подвешен отделенный от этих полюсов упругими проклацками 5, 5 электромагнит 2, несущий записывающее острие 6.In the drawing, schematically depicting a general view of the proposed device, a system of permanent magnets 1 is hung on the axis a and a, between the poles of which on the axis of a with fixedly fixed ends is suspended an electromagnet 2 separated from these poles by elastic proclaims 5, 5 and carrying a recording tip 6.

При пропускании через обмотку электромагнита 2 модулированного тока, сердечник его будет колебатьс .When a modulated current is passed through the winding of the electromagnet 2, its core will oscillate.

при чем строгое соответствие его колебаний с изменени ми силы тока будет обеспечиватьс  не только упругостью прокладок 5, 5, но и тем обсто тельством, что концы оси о о закреилены неподвижно, вследствие чего она при колебани х электромагнита 2 работает на кручение, что вызывает дополнительные усили , стрем щиес  привести электромагнит 2 в среднее положение.whereby the strict correspondence of its oscillations with changes in the current strength will be ensured not only by the elasticity of the gaskets 5, 5, but also by the fact that the ends of the axis are fixedly fixed, as a result of which, with the oscillations of the electromagnet 2, it works for torsion, which causes force seeking to bring the electromagnet 2 to the middle position.

Предмет патента.The subject of the patent.
