Definitions

  • the subject of the invention is a multi-glazed window incorporating an active noise reduction device.
  • the patent document US 6,285,773 discloses an active noise reduction system, comprising one or more linear loudspeakers arranged at the edge of a double glazing, in the air space between the two panes and / or inside a framing profile of this double glazing.
  • the loudspeaker makes it possible to create a practically invisible electro-acoustic system, and which does not adversely affect visual comfort or the light transmission of the glazing, the proposed system making it possible to improve the sound insulation of a double glazing especially at low frequencies.
  • the loudspeaker described in the Carme patent comprises a vibrating membrane arranged between two adjacent panes so as to vibrate and generate counter-noise in the air space.
  • This membrane is associated with an actuator adapted to induce a vibratory movement to said membrane.
  • Electronic control makes it possible to control the actuator according to the acoustic signals picked up by at least one control microphone carried by the window frame.

  • the loudspeaker and the monitoring microphone are in the same plane.
  • the invention aims to remedy this state of affairs.
  • an objective of the invention is to improve the attenuation of noise in a multi-glazed window of the type known from the aforementioned prior art.
  • Another objective of the invention is to obtain noise attenuation in a wide frequency band.
  • the present invention relates to a multi-glazed window, which is characterized by a particular design of the active noise reduction device that it incorporates.
  • the window itself is of the known type.

This transfer function thus previously measured will then be used in the calibration phase for the adaptation of anticipatory filtering elements. This step is carried out in a manner known to those skilled in the art.
  • the active attenuation of the “hybrid” type obtained according to the invention results from a combination of the anticipation and feedback filtering means in which the anticipation filtering is grafted onto the feedback filtering or vice versa.

    - mindestens einen Lautsprecher (HP), der als ein Hohlkörper (1) in Form eines rechteckigen, länglichen Parallelepipeds vorliegt, von dem eine Fläche mindestens teilweise aus einer schwingenden Membran (7) besteht, die zwischen den zwei benachbarten Scheiben (V1, V2) auf eine Weise angebracht ist, um zu schwingen und ein Gegengeräusch in der Luftschicht (L) zu erzeugen, wobei der Hohlkörper (1) eins der Formteile (19a) des Rahmens (19) bildet und die Membran (7) in der Mitte der zwei Scheiben (V1, V2) bezüglich der Mittelebene (P) in Längsrichtung des Fensters auf symmetrische Weise angebracht ist,
    - ein mit der Membran (7) assoziiertes Betätigungselement (11), wobei das Betätigungselement (11) zum Induzieren einer Schwingungsbewegung der Membran angepasst ist,
    - mindestens ein durch den Rahmen (19) getragenes Steuermikrofon (21), wobei das Mikrofon in der Luftschicht (L) installiert ist, um die akustischen Signale in der Luftschicht (L) zu erfassen,
    - eine Steuerelektronik (23), angepasst zum Steuern des Betätigungselements (11) als Funktion der durch das Steuermikrofon (21) erfassten akustischen Signale, gekennzeichnet durch den Umstand, dass:
    - das Steuermikrofon (21) derart von der Mittelebene (P) in Längsrichtung des Fensters versetzt ist, dass es sich näher an der Scheibe (V2) befindet, die die am weitesten entfernte von der Geräuschquelle (S) ist, als an der anderen Scheibe (V1).
  2. Fenster nach Anspruch 1, wobei das Steuermikrofon (21) auf dem durch den Hohlkörper (1) des Lautsprechers (HP) gebildeten Formteil (19a) installiert ist, wobei das Steuermikrofon (21) der Membran (7) benachbart ist.
  3. Fenster nach Anspruch 1, wobei das Steuermikrofon (21) auf einem Formteil (19b) installiert ist, das von dem durch den Hohlkörper (1) des Lautsprechers (HP) gebildeten Formteil (19a) distanziert vorliegt.
  4. Fenster nach einem der Ansprüche 1 bis 3, wobei das Steuermikrofon (21) in eine Richtung orientiert ist, die zu der Ausbreitungsrichtung der akustischen Signale in der Luftschicht (L), die aus der Geräuschquelle (S) stammen, senkrecht ist.
  5. Fenster nach einem der Ansprüche 1 bis 4, wobei die Steuerelektronik (23) ein Filtermittel durch Rückkopplung (FB) umfasst, das einen mit dem Steuermikrofon (21) verbundenen Eingang (FBe) und einen mit dem Betätigungselement (11) verbundenen Ausgang (FBs) besitzt.
  6. Fenster nach einem der Ansprüche 1 bis 5, wobei:
    - mindestens ein Referenzmikrofon (22) durch den Rahmen (19) gehalten wird, wobei das Referenzmikrofon (22) an der Außenseite der Luftschicht (L) auf Höhe der Scheibe (V1) installiert ist, die der Geräuschquelle (S) am nächsten ist,
    - die Steuerelektronik (23) ein Filtermittel durch Antizipation (FF) umfasst, das einen mit dem Referenzmikrofon (22) verbundenen Eingang (FFe) und einen mit dem Betätigungselement (11) verbundenen Ausgang (FFs) besitzt.
  7. Fenster nach Anspruch 6, wobei das Steuermikrofon (21) und das Referenzmikrofon (22) durch das gleiche Formteil (19a) gehalten werden.
  8. Fenster nach Anspruch 6, wobei das Steuermikrofon (21) und das Referenzmikrofon (22) jeweils durch ein unterschiedliches Formteil (19a, 19b) gehalten werden.
  9. Fenster nach einem der Ansprüche 6 bis 8, wobei das Referenzmikrofon (22) in eine Richtung orientiert ist, die zu der Ausbreitungsrichtung der akustischen Signale, die aus der Geräuschquelle (S) stammen, parallel ist.
  10. Fenster nach einem der Ansprüche 6 oder 9, genommen in Kombination mit Anspruch 5, wobei:
    - die Steuerelektronik (23) ein Summierungsmittel (24) umfasst, das einen ersten Eingang (24e1), einen zweiten Eingang (24e2) und einen mit dem Betätigungselement (11) verbundenen Ausgang (24s) besitzt,
    - das Filtermittel durch Rückkopplung (FB) einen mit dem Steuermikrofon (21) verbundenen Eingang (FBe) und einen mit dem ersten Eingang (24e1) des Summierungsmittels (24) verbundenen Ausgang (FBs) umfasst,
    - das Filtermittel durch Antizipation (FF) einen mit dem Referenzmikrofon (22) verbundenen Eingang (FFe) und einen mit dem zweiten Eingang (24e2) des Summierungsmittels (24) verbundenen Ausgang (FFs) umfasst.
  11. Fenster nach einem der Ansprüche 6 bis 10, wobei das Filtermittel durch Antizipation (FF) von adaptiver Art ist und umfasst:
    - einen ersten mit dem Steuermikrofon (21) verbundenen Eingang (FFe1),
    - einen zweiten mit dem Referenzmikrofon (22) verbundenen Eingang (FFe2).
  12. Fenster nach einem der Ansprüche 6 bis 10, wobei das Filtermittel durch Antizipation (FF) von nicht-adaptiver Art ist.
  13. Fenster nach einem der Ansprüche 1 bis 12, wobei der Lautsprecher (HP) ein linearer Lautsprecher ist.
