VALIDATING THE OPERATION OF A TRANSDUCER AND AN AUDIO SIGNAL PATH
First Claim
1. A system to validate the operation of a transducer and an audio signal path to the transducer, the system comprising:
- an audio power amplifier;
an analog-to-digital converter;
an audio switch coupled in the audio signal path, the audio switch configured toswitch the audio signal path between the audio power amplifier and the analog-to-digital converter, androute an audio signal received from the transducer to the analog-to-digital converter when the audio power amplifier is not enabled; and
an electronic processor, coupled to the analog-to-digital converter, and configured toupon receiving an electrical signal indicating that a button has been either actuated or de-actuated, process a digital version of the audio signal received from the analog-to-digital converter to generate a sample,compare the sample to a reference audio sample that represents sound generated when the button is either actuated or de-actuated; and
when the sample does not match the reference audio sample, generate an alert.

Abstract
Systems and methods for validating the operation of a transducer and an audio signal path to the transducer. An example method includes switching, with an audio switch, the audio signal path between an audio power amplifier and an analog-to-digital converter. The method includes routing an audio signal received from the transducer to the analog-to-digital converter when the audio power amplifier is not enabled. The method includes, upon receiving a button signal, processing, with an electronic processor, a digital version of the audio signal received from the analog-to-digital converter to generate a sample. The method includes comparing the sample to a reference audio sample. The method includes generating an alert when the sample does not match the reference audio sample.
