Abstract: In at least one embodiment, a multi-stage sound and vibration sensor is provided. The multi-stage sound and vibration sensor includes a housing, a first piezo-diaphragm and a second piezo diaphragm. The first piezo-diaphragm and the second piezo-diaphragm are positioned in the housing to detect an input signal including audio or vibrations. The first piezo-diaphragm and the second piezo-diaphragm provide a first resonance frequency and a second resonance frequency in response to detecting the audio or the vibrations.

Abstract: A vibration sensor assembly having a rigid surface and a transducer integrated with the rigid surface. The transducer measures structure-borne sound waves that cause vibration motion of the rigid surface. The rigid surface may be glass, metal or plastic and may be part of an interior part or panel, or an exterior panel, of a vehicle.

Abstract: A microphone assembly includes a shaft element that is configured to be received in an opening defined by a base substrate layer of a headliner. The shaft element defines an air path. The microphone assembly includes a microphone element mounted on a circuit board within a housing. The microphone element is aligned with the air path such that the air path directs sound from the cabin to the microphone element. A vehicle cabin side of the headliner is covered by an acoustically transparent layer such that the microphone assembly is not visible within the vehicle cabin.

Abstract: In at least one embodiment, a sound and vibration sensor is provided. The sound and vibration sensor includes a housing, a piezo-diaphragm, and a flexible support plate. The piezo-diaphragm is positioned in the housing to detect an input signal including audio or vibrations. The flexible support plate receives the piezo-diaphragm to enable the sensor to exhibit a frequency response with a plurality of resonant frequencies in response to detecting the audio or the vibrations on the input signal.

Abstract: A microphone assembly includes a printed circuit board that defines a tab that is configured to extend into an opening defined by a substrate layer of a headliner. The microphone assembly includes a microphone element mounted on the tab. The microphone assembly includes a sealing element that surrounds the tab and the microphone element and is configured to fill the opening and define an air path from a cabin side of the substrate layer to the printed circuit board or the microphone element.
