The following description is merely exemplary in nature and is in no way intended to limit the invention, its applications, or uses. For clarity of illustration, like reference numerals will be used in the drawings to identify like elements. As used herein, the terms 'module,' 'circuit,' and / or 'device' are intended to encompass all types of electronic devices, such as an ASIC, an electronic circuit, a processor executing one or more software or firmware programs , Dedicated or grouped) and memory, combinational logic circuitry, and / or other suitable components that provide the described functionality. As used herein, the phrase 'at least one of A, B, and C' should be understood to mean logically A or B or C using non-exclusive logical or . It should be noted that steps in a method may be performed in a different order without changing the basic principles of the invention.

The microphone monitors the noise generated by components of hard disk assemblies (HDDAs) and / or DVD assemblies (DVDAs). Due to the mechanical nature of the HDDA and / or DVDA, noise is generated and / or transmitted by components with loose components such as motors, servo movement, air turbulence, intermittent head crashes, Or various mechanical resonances may be identified using an audio monitor module, as described below. When the resonance mode of the component is detected, the audio monitoring module may increase or decrease the speed of the component by a predetermined amount or by a predetermined percentage. The predetermined amount may include fixed values, fixed percentage values of the current speed, variable values or variable percentage values, progressive values, and / or other appropriate values.

For example, an audio monitor module may utilize sub-band analysis. By monitoring signal levels, frequencies, and noise patterns as well as variations in monitored parameters as a function of time, the operation of HDD and DVD systems can be improved. These systems may automatically adjust the HDD or DVD operating parameters to reduce acoustic noise. By doing so, the user annoyance can be reduced.

The fan operating parameters can be automatically adjusted to lower the acoustic noise. By doing so, the user annoyance may be reduced. Fan operation away from resonance modes can be achieved. In addition, real-time monitoring of fan noise can be used to predict future failures. In order to estimate and monitor the aging of the pan, an analysis of historical data may be performed.

Audio monitoring may also be used in relatively inexpensive ways to differentiate product quality. For example, this approach can be used to separate high quality (or low quality) fans from mid-quality fans. Typically, low noise devices are more reliable than noise-rich ones, especially for fans with identical or similar designs. In addition, real-time monitoring of mechanical components can be used to improve future quality levels.

In addition to or instead of modifying the operating parameters of the components as described above, the audio monitoring module may generate signals to indicate how the components are operating. As an example only, if an element is generating more noise than is typically acceptable, the audio monitoring module may generate an indication signal to the host device. As an example only, if the fan is generating too much noise, the CPU may send an error message to the operating system (OS) to inform the OS and / or the user.
