Patent

CA 2685504

The present invention provides a flat speaker (1), in particular in the aerospace sector, with a panel (2) for generating acoustic signals by vibration of the same, and a vibration exciter (3) which is connected to a panel (2) and excites this to vibrate. Here the panel (2) has an edge stiffening (11...15; 33). This provides the panel (2) with the required stiffness, particularly against hand pressures, but at the same it guarantees high energy efficiency of the flat speaker.

La présente invention concerne un haut-parleur plat (1), en particulier dans le secteur de l'aérospatial, équipé d'un panneau (2) permettant la génération de signaux acoustiques par sa vibration et d'un excitateur de vibrations (3) qui est relié au panneau (2) et excite celui-ci pour qu'il vibre. Par conséquent, le panneau (2) comporte un élément de renforcement (11 ~ 15 ; 33) du bord. Cet élément fournit au panneau (2) la rigidité requise, en particulier contre les pressions manuelles, mais en même temps il garantit un rendement énergétique élevé du haut-parleur plat.
