Abstract: A micro-electromechanical systems (MEMS) package comprising: a MEMS package comprising a substrate and a lid coupled to the substrate; a piezoelectric valve coupled to the substrate and comprising a number of movable members operable to be deformed in opposite directions upon application of a voltage to modify an acoustic resistance of an acoustic port; and a first stopper defined by the substrate and a second stopper defined by the lid, the first stopper and the second stopper being aligned with the number of movable members and operable to prevent an undesirable defection of the number of movable members.

Abstract: Implementations of the subject technology provide for a microphone in the front volume of a speaker. The speaker and the microphone may be provided in a single speaker assembly. The microphone may be implemented as an error microphone or a feedback microphone. The microphone may be mounted to a speaker frame of the speaker, with a sound-sensitive element of the microphone in the front volume of the speaker on a first side of the speaker frame, and with conductive contacts for the microphone disposed on an opposing second side of the speaker frame.

Abstract: A headphone has a driver, an internal microphone, an accelerometer, and an external microphone. An audio processor analyzes signals to detect wind noise. Gain of lower frequencies is reduced relative to higher frequencies, in a first filter that is operating on an audio signal from the external microphone in a feedforward path, responsive to detecting increased wind noise. A second filter in an audio signal feedback path may be adjusted to compensate for the gain change in the first filter that may mitigate occlusion effect. Outputs of the feedforward path in the feedback path are combined to produce an audio signal for the driver. The driver produces sound in the aural canal that has transparency with reduced wind noise, relative to sound external to the headphone. Other aspects are also described and claimed.
