Abstract

"DISPOSIçãO INTRODUZIDA EM SIRENE". Tem por objeto um prático e inovador modelo de dispositivo de som agudo e estridente, pertencente ao campo da eletrónica, de uso mais precisamente como dispositivo sonoro solidário a sistemas de alarme residenciais ou veiculares, e ao qual foi dada original disposição construtiva, incorporando inédito rearranjo de elementos construtivos, visto se tratar de uma sirene dotada de um corpo semiesférico refletor (8), a qual permanece flutuante por dentro de um corpo cilíndrico base-planar difusor (1) contendo uma membrana discoidal (14), contendo solidária um diafragma bipolar (15), conectado eletricamente em dois contatos elétricos (16) contidos em uma tampa discoidal (17) dotada perimetralmente de uma aba anelar (18), que se fecha sob a porção inferior do corpo cilíndrico base-planar difusor (1), sendo que o conjunto formado pelo corpo cilíndrico base-planar dífusor (1) contendo a tampa discoidal (15) se apóia sobre um elemento cilíndrico (19) dentro do qual se aloja um circuito eletrónico (20) alimentado por condutores elétricos (21), sendo que dito circuito se conecta eletricamente aos contatos elétricos (17) contidos em uma tampa discoidal (15)."PROVISION INTRODUCED IN SIRENE". Its purpose is a practical and innovative model of high-pitched high-pitched sound device in the field of electronics, to be used more precisely as a sound device in support of residential or vehicular alarm systems, and to which the original constructive arrangement was incorporated, incorporating an unprecedented rearrangement. of constructive elements, since it is a siren with a semi-spherical reflective body (8), which remains floating inside a base-planar diffuser cylindrical body (1) containing a discoid membrane (14), containing a bipolar diaphragm integrally (15), electrically connected to two electrical contacts (16) contained in a discoid cover (17) provided perimeter with an annular flap (18), which closes under the lower portion of the diffuser base-planar cylindrical body (1), being that the assembly formed by the base-planar cylindrical body diffuser (1) containing the discoid cover (15) rests on a cylindrical element (19) within which a housing is located. electronic circuit (20) powered by electrical conductors (21), said circuit being electrically connected to electrical contacts (17) contained in a discoid cover (15).
