An electronic device for a vehicle comprising circuitry configured to obtain information about a planned maneuver of the vehicle; and circuitry configured to determine the position and/or orientation of a sound field based on the information about the planned maneuver of the vehicle.

Electronic device, method and computer program

An electronic device comprising circuitry configured to obtain an audio signal of a first passenger of a vehicle and to control a loudspeaker array to generate at least one virtual sound source that reproduces the audio signal obtained from the first passenger, the virtual sound source being provided for a second passenger.

An apparatus comprising circuitry configured to generate one or more focused sound sources as virtual loudspeakers of an announcement system.

Apparatus, system, method and computer program for distributing announcement messages

A loudspeaker system comprising a diaphragm () and an electrostatic foil () mounted on top of the diaphragm ().

Loudspeaker system

A device for room geometry analysis comprising: a plurality of segments (-) built of acoustic metamaterials, each segment (&#x3c6;, &#x3b8;) acting as a waveguide with a unique transfer function (B(&#x3c6;, &#x3b8;, &#x3c9;)); and a processor configured to calculate delays (&#x3c4;(&#x3c6;, &#x3b8;)) and respective directions (c(&#x3c6;, &#x3b8;)) of mirror sound sources (-) by decomposing a sound signal (&#x15c;) obtained from a microphone () based on the transfer functions (B(&#x3c6;, &#x3b8;, &#x3c9;)) of the segments (-) and based on a calibration signal (tsp(t)) emitted by a speaker ().

Acoustic metamaterial device, method and computer program

A loudspeaker comprising an acoustic waveguide (), the acoustic waveguide () being configured to change its shape in order to change the directivity of sound emitted by the loudspeaker

Loudspeaker, acoustic waveguide, and method

A device for active noise control inside a vehicle, the device comprising a processor () configured to determine a noise wavefield within the vehicle based on noise signals captured by a microphone array (M-M); determine the position of the ears of a passenger (P) based on information obtained from a head tracking sensor (HTU); capture a noise field inside the vehicle based on information obtained by the microphone array; obtain a noise level at the ears of the passenger (P) from the noise field; and determine an anti-noise field based on the noise level at the position of the ears of the passenger.
