An attachment member is configured to support an electric component to which a harness is connected, and be attached to a wall portion of a vehicle interior. The member includes a base portion to which the electric component is fixed, a first engaging portion and a second engaging portion each standing on the base portion and configured to engage with the wall portion. Each of the first and second engaging portions includes a proximal-side end portion on a side of the base portion, and a distal end-side end portion opposite to the proximal-side end portion. The first and second engaging portions are arranged so as to sandwich a harness connecting portion of the electric component. The attachment member further includes a coupling portion configured to couple the distal end-side end portions of the first and second engaging portions.

An inspection system includes two or more microphone units and an inspection controller. The two or more microphone units are disposed side by side in a vehicle. The inspection controller is configured to cause an inspection-target speaker to output an inspection sound, and determine, on the basis of a sound picked up by a main microphone unit and a sound picked up by one or more satellite microphone units, whether the inspection-target speaker passes or fails. The inspection-target speaker is any of one or more speakers mounted on the vehicle. The main microphone unit is one, of the microphone units, that is disposed at a position corresponding to a position of the inspection-target speaker. The one or more satellite microphone units are each one of the microphone units excluding the main microphone unit.

Systems and methods for mitigating wind throb in vehicles are disclosed herein. An example method includes detecting wind throb in a cabin of a vehicle due to opening of a first window of the vehicle, determining when a seat that is adjacent to a second window of the vehicle is unoccupied, opening the second window when the seat is determined to be unoccupied so as to compensate for the wind throb, determining that the first window has been closed, and closing the second window in response to closing of the first window.

Sound reduction includes receiving a reference signal corresponding to undesired sound present in the target space, and producing, based on the reference signal, a cancelling signal representative of the undesired sound present in the target space. Sound reduction further includes producing, based on the cancelling signal, sound to destructively interfere with the undesired sound present in the target space, and delaying at least one of the reference signal and the cancelling signal to reduce or compensate for runtime differences between signal paths that transfer the reference signal to the target space.

A motor vehicle includes a rear bumper and a microphone. The rear bumper includes an internal cavity that is open towards a front portion of the vehicle. The microphone includes a sound pickup component arranged to acquire a sound signal generated by at least one tire of the vehicle, each of which includes at least one audible wear indicator. The sound pickup component of the microphone is attached to a wall of the rear bumper, and is positioned at a transverse level located between rear tires of the vehicle, preferably in the internal cavity.

Each of the first and second engaging portions includes a proximal-side end portion on a side of the base portion, and a distal end-side end portion opposite to the proximal-side end portion. The first and second engaging portions are arranged so as to sandwich a harness connecting portion of the electric component. The attachment member further includes a coupling portion configured to couple the distal end-side end portions of the first and second engaging portions.

Systems and methods for a transducer assembly for a vehicle having a resonating surface. The transducer assembly comprising a housing, a spacer connected to the housing, and a piezoelectric assembly disposed between the spacer and the housing. The spacer is configured to connect to the resonating surface to form an air gap between the resonating surface and the piezoelectric assembly.

The present disclosure discloses a noise reduction method and apparatus based on in-vehicle sound zones and a medium. The method includes: determining, based on voice signals obtained by sound zones, a target sound zone to which a voice signal waking up a vehicle-mounted terminal belongs, in which each sound zone has a corresponding noise reduction module; and sending a noise reduction termination instruction to noise reduction modules of sound zones other than the target sound zone, in which the noise reduction termination instruction is configured to instruct the noise reduction modules of the sound zones other than the target sound zone to terminate noise reduction algorithms in a process of performing voice interaction for the target sound zone.

Systems for aiding a vehicle driver are disclosed. A system may comprise an imager having a field of view forward relative a vehicle and operable to capture a first image. The system may further comprise a controller communicatively connected to the imager. The controller may be operable to detect a road sign in the first image, to interpret the road sign, and to provide an graphic representation of the road sign and/or provide an auditory response based, at least in part on the road sign. The graphic representation may be displayed by a rear-view assembly. The auditory response may be emitted by a speaker. In some embodiments, a location may be associated with one or more road sign interpretation and both the location and interpretation may be transmitted to a remote server.

A sound control system comprises a sound generating device disposed at a vehicle ceiling corresponding to a seat region of the vehicle and disposed at a sound space formed within the vehicle to correspond to the seat region, and a sound processing circuit for providing a vibration driving signal to the sound generating device, the sound generating device vibrates based on the vibration driving signal to vibrate a vibration region of the vehicle ceiling corresponding to the sound space to provide a sound to the sound space.
