Description

ΠΕΡΙΓΡΑΦΗ DESCRIPTION

Ηλεκτρομαγνητικό σύστημα ηχοληψιας βιολιού Electromagnetic violin tuning system

Η περιγραφόμενη κατασκευή, αναφέρεται σε ηλεκτρομαγνητικό σύστημα ηχοληψίας βιολιού, το οποίο συλλαμβάνει τον ήχο μέσω των δονήσεων των ξύλινων μερών του οργάνου και συγκεκριμένα της γέφυρας. The described construction refers to an electromagnetic violin pickup system, which captures the sound through the vibrations of the wooden parts of the instrument, specifically the bridge.

Οι ως τώρα υπάρχουσες λύσεις περιλαμβάνουν πιεζοηλεκτρικά εμφυτεύματα στα δονούμενα μέρη του οργάνου ή μικρόφωνα τοποθετημένα κοντά ή πάνω στο όργανο. Και οι δυο αυτές λύσεις έχουν τόσο πλεονεκτήματα, όσο και αντίστοιχα μειονεκτήματα. Τα μικρόφωνα είναι γνωστά για την απαράμιλλη ποιότητά τους στην σύλληψη και καταγραφή του ήχου, αλλά είναι επίσης γνωστό ότι στις μεγάλες εντάσεις που απαιτούνται κατά τις μουσικές συναυλίες, εμφανίζουν έντονα προβλήματα ηχητικής ανάδρασης (feedback), πράγμα που καθιστά ως και αδύνατη τη χρήση των. Από την άλλη πλευρά, τα πιεζοηλεκτρικά συστήματα, χωρίς να εμφανίζουν έντονα προβλήματα ηχητικής ανάδρασης, επιβάλλουν στο σύνολό τους έναν άσχημο χρωματισμό στον ήχο, πράγμα που έχει να κάνει με την ιδιοσυχνότητά και τη φύση των υλικών τους, αλλά και τις περισσότερες φορές, απαιτούν την αντικατάσταση μερών του οργάνου στο σύνολό τους ή και τροποποιήσεις στα όργανα, ακόμη και μη αναστρέψιμες, με αποτέλεσμα ανεπιθύμητες συμπεριφορές στην ηχητική απόδοση των οργάνων, και παρεμβάσεις στην αισθητική ή την εμφάνισή αυτών. Existing solutions include piezoelectric implants in the vibrating parts of the instrument or microphones placed near or on the instrument. Both of these solutions have both advantages and disadvantages. Microphones are known for their unparalleled quality in capturing and recording sound, but it is also known that at the high levels required during music concerts, they show strong feedback problems, which makes their use even impossible. On the other hand, piezoelectric systems, without showing strong problems of sound feedback, impose a bad coloring on the sound as a whole, which has to do with the natural frequency and the nature of their materials, but also most of the time, they require the replacement of parts of the instrument as a whole or modifications to the instruments, even irreversible, resulting in undesirable behaviors in the sound performance of the instruments, and interventions in their aesthetics or appearance.

Η παρούσα κατασκευή επιχειρεί να δώσει μια διαφορετική λύση, συνδυάζοντας τα θετικά χαρακτηριστικά και των δύο παραπάνω ομάδων, δηλ. υψηλή πιστότητα χωρίς όμως ηχητική ανάδραση, σε μια λιτή κατασκευή που μπορεί εύκολα να τοποθετηθεί επάνω στο σώμα του οργάνου (7) χωρίς την παραμικρή τροποποίηση ή οποιαδήποτε επέμβαση σε αυτό. The present construction attempts to provide a different solution, combining the positive characteristics of both groups above, i.e. high fidelity but without sound feedback, in a simple construction that can be easily placed on the body of the instrument (7) without the slightest modification or any intervention thereon.

Το πλήρες σύστημα αποτελείται από ένα σύστημα δύο πηνίων (1) με φερρομαγνητικό πυρήνα και αντίθετη φορά περιέλιξης συνδεδεμένα ηλεκτρικά σε σειρά, σε συνδυασμό με ένα μόνιμο μαγνήτη (2) ο οποίος εφάπτεται στον πυρήνα τουλάχιστον του ενός εξ αυτών των πηνίων και δημιουργεί μαγνητικό πεδίο γύρω από αυτά τα πηνία (1), τα οποία πηνία (1) και ο μαγνήτης (2) είναι εγκιβωτισμένα και στερεωμένα στο άκρο ενός αποσπώμενου μηχανικού βραχίονα (3), ο οποίος βραχίονας (3) τοποθετείται-συσφίγγεται μηχανικά στο μη δονούμενο πλευρό του οργάνου και του οποίου βραχίονα (3) το προαναφερόμενο άκρο εκτείνεται απολύτως σύνεγγυς και αντικριστά της πλευρικής σχισμής (4) της γέφυρας (5) του οργάνου, χωρίς όμως άμεση επαφή με αυτή, καθώς και από ένα δίσκο (6) με φερρομαγνητικές ιδιότητες ο οποίος τοποθετείται-συσφίγγεται εντός της πλευρικής σχισμής (4) της γέφυρας (5) του οργάνου, όπου αφ’ ενός το σύστημα των πηνίων (1) με το μόνιμο μαγνήτη (2) και αφ’ ετέρου ο δίσκος (6), βρίσκονται σε ανέπαφη λειτουργική συγγένεια-σχέση μεταξύ των (Fig. 1). The complete system consists of a system of two coils (1) with a ferromagnetic core and opposite winding electrically connected in series, in combination with a permanent magnet (2) which contacts the core of at least one of these coils and creates a magnetic field around of these coils (1), which coils (1) and the magnet (2) are encased and fixed to the end of a detachable mechanical arm (3), which arm (3) is mechanically position-clamped to the non-vibrating side of the instrument and whose arm (3) the aforementioned end extends absolutely close to and opposite the lateral slit (4) of the bridge (5) of the instrument, but without direct contact with it, as well as by a disk (6) with ferromagnetic properties which is placed - it is clamped inside the lateral slot (4) of the bridge (5) of the instrument, where on the one hand the system of coils (1) with the permanent magnet (2) and on the other hand the disc (6) are in intact functional contact news-relationship between (Fig. 1).

Πιο συγκεκριμένα, το σύστημα των πηνίων (1) με το μαγνήτη (2), προσομοιάζουν στο σύνολό τους την αρματούρα ενός δυναμικού μικροφώνου και στερεώνονται ακίνητα και μη δονούμενα, με τη βοήθεια του μηχανικού βραχίονα (3), απολύτως σύνεγγυς και αντικριστά της πλευρικής σχισμής (4) της γέφυρας (5) του οργάνου, με το μαγνήτη (2) να βρίσκεται αντικριστά σε αυτήν τη σχισμή (4) και σε απόσταση από αυτήν τέτοια που μόλις να μην έρχονται σε άμεση επαφή, ενώ ο παραπάνω δίσκος (6) αναλαμβάνει το ρόλο του διαφράγματος αυτού του μικροφώνου, καθώς αυτός σφηνωμένος εντός της πλευρικής σχισμής (4) της γέφυρας (5), ακολουθεί πιστά και αναλογικά τις δονήσεις της γέφυρας (5) του οργάνου, οι οποίες δονήσεις προκύπτουν κατά τη δόνηση των χορδών (8) του οργάνου, και διαταρράσει ο δίσκος (6) δονούμενος το μαγνητικό πεδίο που δημιουργείται από τον μαγνήτη (2) στην περιοχή της πλευρικής σχισμής (4) της γέφυρας του οργάνου (5) και ως εκ τούτων παράγεται επαγωγικά ηλεκτρική τάση στα άκρα των εφαπτόμενων στο μαγνήτη (2) πηνίων (1), η οποία μεταφέρεται με εξωτερική καλωδίωση (9) σε ενισχυτή και η οποία τάση ακολουθεί με πιστότητα τον ήχο του οργάνου (7) (Fig. 1). More specifically, the system of the coils (1) with the magnet (2), simulate as a whole the armature of a dynamic microphone and are fixed immobile and non-vibrating, with the help of the mechanical arm (3), absolutely close to and facing the side slot (4) of the bridge (5) of the instrument, with the magnet (2) facing this slot (4) and at a distance from it such that they hardly come into direct contact, while the above disc (6) takes over the role of the diaphragm of this microphone, as it is wedged inside the lateral slot (4) of the bridge (5), faithfully and proportionally follows the vibrations of the bridge (5) of the instrument, which vibrations arise during the vibration of the strings (8) of the instrument, and the disk (6) is disturbed by vibrating the magnetic field created by the magnet (2) in the area of the side slot (4) of the bridge of the instrument (5) and as a result an electric voltage is inductively produced at the ends of the tangents in magnet (2) of coils (1), which is transferred by external wiring (9) to an amplifier and whose voltage faithfully follows the sound of the instrument (7) (Fig. 1).
