Abstract
A miniaturized acoustic boom structure includes a microphone boom housing having a wind screen and a microphone pod configured to hold a microphone. The microphone pod has an outer surface secured to an inner surface of the microphone boom housing, an interior having one or more surfaces configured to form an acoustic seal around at least a portion of the periphery of the microphone, and first and second pod port openings. The first and second pod port openings provide sound wave access to opposing sides of a diaphragm of the microphone, and are shaped and spaced away from the first and second microphone ports of the microphone so that an acoustic path length between the first and second pod port openings is greater than an acoustic path length between the first and second microphone ports.
