Abstract: A loudspeaker arrangement comprises a mid-range loudspeaker arranged in a dashboard of a vehicle, a first tweeter arranged adjacent to the mid-range loudspeaker in the dashboard of the vehicle, and a second tweeter arranged adjacent to the mid-range loudspeaker in the dashboard of the vehicle. The mid-range loudspeaker is arranged between the first tweeter and the second tweeter. The mid-range loudspeaker is a non-directional loudspeaker that radiates sound towards a driver’s seat and towards a passenger seat in equal parts. The first tweeter is a directional loudspeaker that radiates sound primarily towards the passenger seat, and the second tweeter is a directional loudspeaker that radiates sound primarily towards the driver’s seat.

Abstract: A loudspeaker arrangement comprises an enclosure, at least one loudspeaker mounted in a wall of the enclosure between the inside and the outside of the enclosure and configured to produce sound waves, a first passive radiator mounted in a first wall of the enclosure between the inside and the outside of the enclosure, a second passive radiator mounted in a second wall of the enclosure between the inside and the outside of the enclosure, and a connecting element connecting the first passive radiator to the second passive radiator.

Abstract: An in-vehicle noise-cancellation system may optimize far-end user experience. The noise-cancellation system may incorporate real-time acoustic input from the vehicle, as well microphones from a telecommunications device. Audio signals from small, embedded microphones mounted in the vehicle can be processed and mixed into an outgoing telecom signal to effectively cancel acoustic energy from one or more unwanted sources in the vehicle. Multiple microphones may be mounted to headrests and spaced apart in one or more directions to give an indication of the direction of incoming sound from one or more listening zones so that sounds from certain zones may be suppressed. Unwanted noise captured by the embedded microphones may be used as direct inputs to the noise-cancellation system. As direct inputs, these streams can, therefore, be cancelled from the outgoing telecom signal, thus providing the user's far-end correspondent with much higher signal-to-noise ratio, call quality, and speech intelligibility.

Abstract: A portable loudspeaker having a sound generating unit configured to output a sound signal with a stand-alone frequency characteristic when the portable loudspeaker is used in a stand-alone operating mode and to output a sound signal with a connected frequency characteristic when the portable loudspeaker is used in a connected operating mode. The connected operating mode is defined when the portable loudspeaker is received by a docking module in a vehicle and is configured to enhance a bass output as compared to the stand-alone frequency characteristic.
