Description

Einrichtung zur verstärkten und lautgetreuen Wiedergabe von Sprache und Tönen. Es ist vielfach versucht worden, die durch Sprachströme bewirkten elektromechanischen Bewegungen dazu zu benutzen, um einen Gas-oder Dampfstrom in seiner Austrittsgeschwindigkeit zu beeinflussen und auf diese `Weise eine laute Sprache zu erzielen. Das geschieht, indem der Querschnitt des Luftantrittsrohres entsprechend den Schallschwingungen elektromagnetisch geändert 'wird.Device for amplified and faithful reproduction of speech and sounds. Many attempts have been made to reduce the electromechanical effects caused by speech currents Movements to use to a gas or vapor stream in its exit velocity to influence and in this way to achieve a loud speech. This happens, by the cross-section of the air inlet pipe according to the sound vibrations is changed electromagnetically '.

Alle diese bisherigen Versuche sind daran gescheitert, daß es nicht möglich war, die notwendigen Ventile oder sonstigen Drosseln so massenlos herzustellen, daß sie selbst den sehr schnellen Schwingungen, welche den höchsten Obertönen entsprechen, nachkommen könnten.All these previous attempts have failed because it does not it was possible to manufacture the necessary valves or other throttles so masslessly, that they even respond to the very rapid vibrations which correspond to the highest overtones, could follow.

Ein weiterer Nachteil aller dieser Einrichtungen bestand darin, daß der Luftstrom, wem er an. härten und scharfen Kanten oder Kurven vorbeistreicht, diese durch Pfeifenwirkung zum Tönen bringt und die Modulation zu grob und hart wird.Another disadvantage of all of these devices was that the airflow to whom it is directed. harden and sweep past sharp edges or curves, makes this sound through the whistle effect and the modulation too coarse and hard will.

Im Gegensatz hierzu ist bei der vorliegenden Erfindung der Mechanismus des menschlichen Kehlkopfes bis zu einem bestimmten Grade nachgeahmt worden, indem die Austrittsöffnung eines Luftstromes dadurch geändert wird, daß der Durchmesser eines aus Kautschuk oder ähnlichen weichen Materialien hergestellten schlauchartigen Körpers durch mechanische Bewegungen, welche im Rhythmus der Sprache ausgeführt werden, auf mechanischem bzw. elektromagnetischem Wege verändert wird. Wenn gleichzeitig ein Luftstrom durch das schlauchartige Gebilde hindurchgeschickt wird, so ergibt sich mit sehr einfachen Mitteln eine laute und selbst in der Klangfarbe gute Wiedergabe der menschlichen Sprache.In contrast, in the present invention, the mechanism is of the human larynx has been mimicked to some extent by the outlet opening of an air stream is changed in that the diameter a hose-like made of rubber or similar soft materials Body through mechanical movements that are carried out to the rhythm of speech is changed in a mechanical or electromagnetic way. If at the same time a stream of air is sent through the hose-like structure, so results With very simple means a loud and even sound reproduction can be achieved of human language.

Es empfiehlt sich auch, insofern den Mechanismus des menschlichen Sprachorgans nachzubilden, als man das freie Ende des schlauchartigen Gebildes zu einem halb oder weniger offenen Resonator für eine mittlere Schwingungszahl ausbildet.It is also recommended insofar as the mechanism of to simulate the human organ of speech than the free end of the hose-like Formed into a half or less open resonator for a medium number of oscillations trains.

Die Erfindung ist auf der Zeichnung in einem Beispiel schematisch erläutert.The invention is shown schematically in an example in the drawing explained.

a und b sind die Anschlußklemmen für die ankommenden Sprechströme, M ein vormagnetisierter Elektromagnet, A der Anker des Steuerorgans zur Querschnittsänderung, D die Austrittsöffnung, L der Luftschlauch, R der der Mundhöhle entsprechende Resonator, W ein Windkessel, T der Schalltrichter.a and b are the connection terminals for the incoming speech streams, M a pre-magnetized electromagnet, A the armature of the control element for changing the cross-section, D the outlet opening, L the air tube, R the resonator corresponding to the oral cavity, W an air chamber, T the bell jar.

Aus mehreren solchen sinngemäß zu verändernden Gliedern kann man eine akustische Verstärkerkaskade bilden, indem man die Deformation eines vorhergehenden Apparates zur Steuerung des nächstfolgenden ausnutzt.One can create one from several such terms that can be changed accordingly Form acoustic amplifier cascade by taking the deformation of a previous one Apparatus used to control the next one.
