Abstract
Flow guides in the form of extensions that project internally from the housing of an electronic consumer device can contribute to undesirable noise emissions from the device. Proposed is an improved flow guide or extension that reduces propagation of flow induced vibrations to the housing, thereby improving the overall acoustic performance of the device.
