Abstract

Μέθοδος κατασκευής ηχείων και υλοποίησή της σε ηχεία, τα οποία χαρακτηρίζονται από την τοποθέτηση των μεγαφώνων μεσαίων και υψηλών συχνοτήτων επάνω και πλαγίως, υπό γωνία ως προς την πρόσοψη. Πλεονεκτήματά τους, σε σχέση με τα ηχεία της υπάρχουσας τεχνολογίας είναι η επίπεδη απόκριση συχνοτήτων στον οριζόντιο άξονα (on Axis) ταυτόχρονα με ίδιας στάθμης επίπεδη απόκριση Ακουστικής Ισχύος (Sound Power) και σταθερή σχεδόν μηδενική κατευθυντικότητα (Directivity). Πρόσθετο πλεονέκτημα είναι ότι οι 2 συνιστώσες της Sound Power στο οριζόντιο και στο κατακόρυφο επίπεδο είναι ισορροπημένες σε ίδια στάθμη. Αναλόγως της γωνίας (ως προς την πρόσοψη) τοποθέτησης των μεγαφώνων μεσαίων και υψηλών συχνοτήτων η εμπρόσθια ηχητική ακτινοβολία (on Axis) μπορεί να είναι σταθερά μικρότερη της (σταθερής και ανεξάρτητης από την γωνία) ακουστικής ισχύος (Sound Power) από 3db έως 5dB, ώστε το ηχείο να προσφέρει την ιδανική αίσθηση χώρου. Η εφεύρεση μπορεί να υλοποιηθεί ως κάθε μεγέθους και χρήσης ηχεία, προσφέροντας σημαντική βελτίωση στην ποιότητα του ήχου, τόσο εμπρός στο ηχείο, όσο και στην ηχητικού πεδίου στον χώρο, δημιουργώντας μια πολύ πιο ρεαλιστική εικόνα και διευρύνοντας ιδανικά τον χώρο ακρόασης.
