Pillow speaker relay circuit, pillow speaker, and method for same
The present disclosure provides a method for determining a presence of a relay in a pillow speaker, including sampling a voltage of a relay drive line to detect a first feedback state; providing a control signal to activate the relay drive line; sampling a voltage of the relay drive line during activation to detect a second feedback state; and comparing the first feedback state and the second feedback state to detect a presence of a relay. In another aspect, a pillow speaker relay circuit includes a relay drive line with a relay terminal configured to connect to a relay such that current flows through the relay when the relay drive line is activated; a control circuit operable to activate the relay drive line, and a feedback detection circuit configured to detect a voltage of the relay drive line; and a controller to perform any of the disclosed methods.
