Abstract
1. A security window comprising a recess in the counter (4, 4a) the median section of which is located unterneath a security glass panel (2, 2a) abutting the counter (1, 1a) on both sides of the recess (4, 4a), said recess consisting of at least one thin element (5, 6) capable of vibrating and further comprising the moving component of an electro acoustic transducer (7, 9) attached underneath said thin element so as to cause it to vibrate in the manner of a loudspeaker diaphragm when actuated by at least one microphone (11, 12), characterized in that the recess (4, 4a) consists of two half recesses (5, 6) separated by a joint (17) which prevents the vibrations of one the two half recesses (5, 6) from reaching the other half recess with each thin element which constitutes one half recess being located on one of the two opposite sides of the glass panel (2, 2a) and further being operatively connected to one electro acoustic transducer (7, 9) actuated by a microphone (11, 12), and in that the microphone (11, 12) actuating the electro acoustic transducer (7, 9) of one of the two half recesses (5, 6) is positioned underneath the other half recess.
