Description
Предлагаемое изобретение имеет целью получение громкоговор щего телефона посредством использовани известного влени прит жени между проводниками и полупроводниками.The present invention aims at obtaining a loudspeaker telephone by utilizing the well-known attraction between conductors and semiconductors.
На схематическом чертеже изображен телефон.The schematic drawing shows a telephone.
Металлическа мембрана В зажата между полуцилиндрическими полупроводниками А, А, А, А, при чем полупроводники (например, литографский камень) А н А- (А и А ) обращены друг к другу обточенными цилиндрическими поверхност ми. Электрический ток идет по двум проводникам х у, из которых проводник X прикреплен к мембране В а проводник у, при помощи цепей у, У2, к полупроводникам А А, AZ, А. В каждую из этих цепей включены, навстречу друг другу,The metal membrane B is sandwiched between semi-cylindrical semiconductors A, A, A, A, and the semiconductors (for example, the lithographic stone) A n A - (A and A) face each other with turned cylindrical surfaces. Electric current flows through two conductors x y, of which conductor X is attached to the membrane B and the conductor y, with the aid of the y, U2 circuits, to the semiconductors A A, AZ, A. Each of these circuits is connected, opposite to each other,
по одному контактному детектору С и Со. Предполагаетс , что силы прит жени будут значительными и что телефон будет громко-говор щим.on one contact detector With and With. It is assumed that the attractive forces will be significant and that the phone will be loud.
ПРЕДМЕТ ПАТЕНТА.SUBJECT OF THE PATENT.
Телефон, характеризующийс совокупным применением: а) четырех полупроводников AI и А (А и А), обточенных с одной стороны по цилиндрической поверхности, при чем полупроводники AI и А (А и Л ) обращены друг к другу цилиндрическими поверхност ми , б) металлической мембраны В, зажатой между цилиндрическими поверхност ми полупроводников AI и Ло (J и А), в) двух детекторов С и Q, включенных навстречу друг другу в один из токоподвод щих проводов.A telephone characterized by cumulative use: a) four semiconductors AI and A (A and A), ground on a cylindrical surface on one side, with AI and A semiconductors (A and L) facing each other with cylindrical surfaces, b) a metal membrane B, sandwiched between the cylindrical surfaces of the semiconductors AI and Luo (J and A), b) of two detectors C and Q, connected in opposite directions to one of the lead wires.
