Abstract

The invention relates to a microphone assembly (100) for acquiring a plurality of audio signals, wherein the microphone assembly (100) has a reconfigurable geometry so that the microphone assembly (100) may be configured to be embedded in or attached to a body. The microphone assembly (100) comprises: a plurality of digital microphones (101a-h) configured to convert the sound signal impinging on each digital microphone into a corresponding digital electrical signal, in particular a Pulse- Code-Modulation (PCM) or a Pulse-Density-Modulation (PDM) digital serial electrical signal; a digital signal processing unit (102) comprising a serial digital communication interface (102a) and a processor (102b), wherein the serial digital communication interface (102a) is configured to receive the electrical signals provided by the plurality of digital microphones (101a-h), and wherein the processor (102b) is configured to store, transmit, and/or process the digital electrical signals provided by the plurality of digital microphones (101a-h); and a connecting and mounting structure configured to provide a flexible electrical connection and a flexible mechanical arrangement for the plurality of digital microphones (101a-h), wherein the connecting and mounting structure comprises a plurality of wired connections configured to connect the plurality of digital microphones (101a-h) with the serial digital communication interface (102a) in such a way that at least one of the plurality of digital microphones (101a-h) is moveable relative to the others.
