Abstract: A system includes a first housing that houses a plurality of mechanical keys. A first microphone that is configured to detect a dynamic noise is located within the first housing and under the mechanical keys. A second microphone is configured to detect acoustic waves that include speech and to convert the acoustic waves into an electrical audio signal. The dynamic noise is not associated with the detected speech. The system further includes a dynamic audio signal filter that is configured to suppress, in the electrical audio signal, dynamic noise, and the dynamic audio signal filter is activated in response to the first microphone detecting the dynamic noise.

Abstract: Apparatuses that provide a bone-conduction speaker arranged to be located behind the ear are described herein. An exemplary apparatus may include: (a) a glasses-style support structure comprising a front section and at least one side section; (b) at least one bone-conduction speaker; and (c) a member having a proximate end and a distal end, wherein the proximate end is attached to the at least one side section, and wherein the at least one bone-conduction speaker is attached to the member at or near the distal end; wherein the member is arranged on the at least one side section such that when the glasses-style support structure is worn the member: (a) extends to the anterior of the at least one side section and (b) locates the bone-conduction speaker posterior to an ear.
