Description

Elektrisches Musikinstrument auftritt. Da die durch die Feldkonzentration hervorgerufenen Spannungen erheblich größer sind als die ohne das Zusatzfeld bereits vorhandenen, sind sie ausschlaggebend für die Klangfarbe. Durch Feldkonzentrationen an mehreren Punkten kann noch eine weitere Mannigfaltigkeit an Klanglarbenerzielt werde.. Der Obertongehalt der erzeugten elektrischen Schwingung kann noch dadurch verschieden gemacht werden, daß man. das Feld zum schwingenden Leiter in einer bestimmten Richtung orientiert. So erhält man z. B. bei einem Feld, das parallel zum Leiter verläuft, die Doppelfrequenzen der im Leiter vorhandenen Teiltonschwingungen. Bei elektrischen Musikinstrumenten, bei denen die Schwingungen mechanischer Schwingungserzeuger in elektrische Schwingungen umgewandelt werden, wurde auch schon das elektrodynamische Prinzip benutzt. Der leitende Schwingungskörper, z. B. die Saite, schwingt dabei; m einem magnetischen Feld, wodurch in der Saite die Wechselspannungen .erzeugt werden. Dazu wurde zweckmäßig ein möglichst ausgedehntes Feld benutzt. Der dabei erzeugte Wechselstrom war in seiner Kurvenform im wesentlichen durch die Schwingungsform des Schwingungserzeugers gegeben.Electric musical instrument occurs. Because the by the field concentration The voltages caused are considerably greater than those without the additional field existing, they are decisive for the timbre. By field concentrations At several points a further variety of sound patterns can be achieved will .. The overtone content of the generated electrical oscillation can still be thereby be made different that one. the field to the vibrating ladder in a certain Direction oriented. So you get z. B. in a field that is parallel to the conductor runs, the double frequencies of the partial tone oscillations present in the conductor. at electrical musical instruments in which the vibrations are mechanical vibrators are converted into electrical vibrations, it became electrodynamic Principle used. The conductive vibrating body, e.g. B. the string vibrates; m a magnetic field, whereby the alternating voltages are generated in the string. For this purpose, a field that was as extensive as possible was used. The one generated in the process Alternating current was essentially waveform in its waveform given by the vibrator.

Bei. schwingenden Salben tritt an den Enden auch ohne besondere Anordnung eines Feldes eine gewisse elektrische Spannung auf. Bei entsprechender Verstärkung dieser Spannung könnte also in diesem Falle ohne weiteres damit ein Lautgprecher betrieben werden. Da aber bei elektrischen Musikinstrumenten in verschiedenen Klangfarben gespielt werden soll, werden Kurvenformen benötigt, die von der des mechanischen Schwingungserzeugers erheblich abweichen. Deshalb werden @erfmdungsgemäß Feldkonzentrationen durch besondere; an bestimmten Punkten. des Schwingungserzeugers. angeordnete Magnete vorgenommen, wodurch gerade die an diesem Punkt vorhandene Sc!hrovingungsform in der elektrischen SchwingungAt. vibrating ointments occurs at the ends even without any special arrangement a certain electrical voltage. With appropriate reinforcement this voltage could in this case easily be a loudspeaker operate. But since with electric musical instruments in different timbres is to be played, curve shapes are required that are different from that of the mechanical Vibration generator differ considerably. Therefore, according to the invention, field concentrations are by special; at certain points. of the vibrator. arranged magnets made, whereby the roving shape present at this point in the electrical oscillation
