A top case for a motor vehicle, in particular a motorcycle or a motorcycle-type motor vehicle, includes an integrated loudspeaker arrangement with a loudspeaker casing and at least one loudspeaker that is connected to the loudspeaker casing. The top case at least partially forms the loudspeaker casing. The loudspeaker casing includes a horn-shaped duct that is connected in an air-conducting manner to a rear side of the loudspeaker.

Collision/fall reporting and alert systems and methods for micromobility vehicles include at least one proximity sensor, a speed sensor, at least one tilt sensor, a global positioning system, at least one warning device, a communication device, and a controller in communication with the at least one proximity sensor, the speed sensor, the at least one tilt sensor, the global positioning system, the at least one warning device, and the communication device.

The present invention provides a detachable multimedia control apparatus, comprising: a front housing structure including a left turn signal, a right turn signal and a central light; a rear housing structure including a speaker module and a safety switch module; a top housing structure including a control module which controls the speaker module and the central light; a bottom housing structure including a first joining structure; a processor disposed inside the movable multimedia control apparatus and electrically connected to the left turn signal, the right turn signal, the central light, the speaker module, the safety switch signal and the control module; and a power module disposed inside the detachable multimedia control apparatus and electrically connected to the left turn signal, the right turn signal, the central light, the speaker module, and the processor, wherein the power module is configured to be unlocked by the safety switch module.

Described herein are systems and methods for motorbike collision avoidance. One or more sensors or devices can be used to monitor the operating conditions of a motorbike and, upon a determination that a collision or drop has occurred, or is likely to occur, an alert system can be activated. The alert system can comprise one or more auxiliary illumination devices and/or acoustic devices configured to draw the attention of other motorists. The alert system may aid the other motorists in noticing the motorbike and approximating the motorbike's position, size, distance, or speed. The alert system can also be activated by the motorbike rider to communicate to other motorists that the rider believes a collision is possible or that a situation requires caution.
