Description

В предлагаемом микрофоне, относ щемс  к типу контактных микрофонов, подвижна  часть, на которую непосредственно воздействует мембрана, выполн етс  в виде угольной спирали трехгранного сечени .In the proposed microphone, related to the type of contact microphones, the movable part, which is directly affected by the membrane, is made in the form of a carbon helix with a triangular cross section.

На схематическом чертеже фиг. 1 и 2 изображает подобную спираль в двух проекци х, при чем на фиг. 2-в разрезе .In the schematic drawing of FIG. 1 and 2 depicts a similar helix in two projections, and FIG. 2-section.

В микрофоне применена угольна  спираль трехгранного стечени , каждый виток которой со прикасаетс  с соседним, при чем ребро верхнего витка опираетс  на грань (в середине ее) нижнего. У вершины , где высыпает последний виток, помещаетс  мембрана (обыкновенна A microphone coil of a triangular confluence is applied in the microphone, each coil of which touches the adjacent coherence, and the edge of the upper coil rests on the face (in the middle of it) of the lower one. At the top, where the last turn pours out, a membrane is placed (ordinary

мембрана микрофона), прилегающа  своей серединой к выступу последнего витка (фиг. 2). При колебании мембраны витки спирали будут в большей или меньшей степени давить друг на друга, что скажетс  соответственным образом на величине протекающего через микрофон тока.microphone membrane), adjacent to its middle to the ledge of the last round (Fig. 2). When the membrane oscillates, the turns of the helix will more or less push each other, which will affect the current flowing through the microphone accordingly.

Предмет изобретени .The subject matter of the invention.

Контактный микрофон, отличающийс  применением угольной спирали трехгранного сечени , устроенной так, что ребра одного хода спирали опираютс  о грани другого, свободный конец каковой спирали опираетс  о мембрану.A contact microphone characterized by the use of a triangular-angle carbon helix, arranged so that the ribs of one helix stroke rests on the face of another, the free end of which helix rests on the membrane.
