Abstract

Μεγάφωνο που περιλαμβάνει περίβλημα και μεμβράνη τοποθετημένη εντός του εν λόγω περιβλήματος, η οποία μεμβράνη μπορεί να δονείται ώστε να παράγει ήχο, όπου το μεγάφωνο διαθέτει τουλάχιστον ένα κανάλι ήχου που εκτείνεται μεταξύ της μεμβράνης και της εξωτερικής πλευράς του περιβλήματος, και όπου στο κανάλι ήχου υπάρχουν ένα ή περισσότερα τοπικά φράγματα ήχου, τα οποία φράγματα ήχου μπλοκάρουν τοπικά τουλάχιστον το 15% της επιφάνειας εγκάρσιας διατομής του καναλιού ήχου, έτσι ώστε να προκύπτει ενίσχυση της ηχητικής πίεσης στο ακουστικό φάσμα συχνοτήτων λόγω συντονισμού.
