Abstract

A time-division-multiplexing (TDM) based noise cancelation headphone is presented herein. A headphone can include an earbud including a speaker, and a TDM based bus that electrically couples the earbud to a portable electronic device. Further, the headphone can include a first micro-electro-mechanical system (MEMS) microphone that is configured to receive a first set of acoustic waves outside of an ear canal, generate first microphone information based on the first set of acoustic waves, and send, utilizing the TDM based bus, the first microphone information directed to the portable electronic device. The speaker is configured to receive, utilizing the TDM based bus, feedforward noise cancelation information associated with the first microphone information from the portable electronic device, and generate, based on the feedforward noise cancelation information, sound within a portion of the ear canal.
