verhindern Lautsprecher und Mikrofon Feedback?
Ich wollte wissen, wie kann ich Feedback Ort ein Mikrofon hinter einem nackten Lautsprecher, ohne magnetische Störungen oder. Was Ich bin auf einem Kostüm arbeitet mit einer halben Atemschutzmaske verwandelte sie in einen kühlen Gasmaske Ich war Ort einer Stimme Wechsler und setzen in allen Teilen in der "Filter (s)" oder die Basis der Maske.
Diese ist hart werden würde. Wenn das Mikrofon Abholung Ihrer Stimme direkt neben einem Lautsprecher, Verstärken Sie Ihre Stimme Sie versuchen, gegen die Gesetze der Physik zu gehen. Das Mikro holt den Ton vom Lautsprecher, wenn Sie separate das Mikrofon und Lautsprecher akustisch. Sie haben etwas zwischen den beiden setzen wie Holz oder Metall – Holz wird besser sein. Holen Sie sich so viel Abstand zwischen den beiden, wie Sie können. Was Sie versuchen zu verhindern, ist das Mikrofon aus "Hören" der Ton aus dem Lautsprecher – das ist die Ursache Feedback. Es könnte einfacher sein, nur ein Spielzeug Voice Changer kaufen und machen es fit in der Maske; http://www.amazon.com/Hasbro-Transformers-Optimus-Changer-Helmet/dp/B000LDSIRI/ref=sr_1_1?ie=UTF8&s=toys-and-games&qid=1283352271&sr=8-1 http:// www.amazon.com/Multi-Voice-Changer-Toysmith-different/dp/B000FK3WDC/ref=sr_1_fkmr0_1?ie=UTF8&qid=1283352271&sr=8-1-fkmr0
