Abstract

Sistema de detección de estado de tomas de auriculares, que consta de un circuito captador comprobador de la impedancia (Z) de las líneas que conducen la señales de audio; el cual circuito captador incluye, por cada toma de auricular a comprobar, un conector-hembra con dos contactos, uno por canal, que se abren cuando se inserta el conector-macho de los auriculares; yendo asociado dicho circuito captador a un comparador (amplificador operacional) controlado por microprocesador en el que previamente se ha establecido un valor (Zo) como impedancia de referencia con la cual establecer la comparación; de modo que, cuando dicho comparador detecta un valor de impedancia mayor que (Z0) el comparador cambia de estado en su salida generando una tensión opuesta a la establecida en funcionamiento normal. De aplicación en electrónica.Headphone jack status detection system, consisting of an impedance tester (Z) sensor circuit of the lines that conduct the audio signals; which sensor circuit includes, for each headphone jack to be checked, a female connector with two contacts, one per channel, which open when the headphone male connector is inserted; said collector circuit being associated with a comparator (operational amplifier) controlled by a microprocessor in which a value (Zo) has previously been established as the reference impedance with which to establish the comparison; so that when said comparator detects an impedance value greater than (Z0), the comparator changes state at its output generating a voltage opposite to that established in normal operation. Application in electronics.
