Disclosed are an audio information transmission system, method, and apparatus, and a corresponding two-wheeled vehicle and helmet. The system includes a media control apparatus and an audio switching apparatus connected to the media control apparatus. The audio switching apparatus is connected to a mobile terminal and the helmet and is configured to receive first audio information transmitted by the mobile terminal and transmit same to the media control apparatus. The media control apparatus is configured to receive and mix second audio information generated by the two-wheeled vehicle with the first audio information, to generate mixed audio information. The audio switching apparatus transmits the mixed audio information to the helmet. In the present application, the audio information transmitted by the mobile terminal and information such as navigation voices, alarms emitted by the two-wheeled vehicle are mixed. The mixed audio information is transmitted to the helmet, so that the user can obtain both the audio information transmitted by the user terminal and the navigation voices transmitted by the electric vehicle, without switching between the audio information from the mobile terminal and the navigation voices emitted by the electric vehicle. The user's driving safety is improved and the user experience is enhanced.

A helmet for a rider of an on-road or off-road vehicle protects the rider's head. The helmet also may include various features for enhancing the riding experience. For example, the helmet may include electrical connections for power various features of the helmet. Additionally, the helmet may include earmuffs which reduce road or other noises during operation of the vehicle.

An integrated helmet includes: a helmet body, defining a wearing space, a flip cover coupled pivotally to the helmet body; a pair of glasses, configured on the helmet body and positioned relatively inside the flip cover, and generating a virtual reality image; and a first filter device, configured inside the helmet body. The integrated helmet 1 is provided with the flip cover to protect the smart glasses inside the flip cover, and can generate interactive VR images; the helmet body is provided with the first filter device to filter suspended particles in the air, such as viruses, dust, impurities, etc., achieving the improved epidemic prevention.

An adapter assembly for attaching a circumaural device to a mounting interface on a helmet comprises a fastener element configured to releasably couple to the mounting interface. A pressure relief assembly coupled to the fastener element has a pivoting subassembly and an adjustment subassembly. The pivoting subassembly I pivotable about a pivot axis and has a range of travel between an upright position and an extended position. One or more attachment arms have a proximal end coupled to the pressure relief assembly and a distal end for attaching the circumaural device. The adjustment subassembly has a manually operable control portion to cause pivoting movement of the pivoting subassembly toward the upright position to decrease a pressure of an attached circumaural device on a wearer's head or toward the extended position to increase a pressure of an attached circumaural device on the wearer's head.

Implementations of a ballistic helmet having an integrated electronic circuit are provided. An example ballistic helmet includes: a first armor plate attached by a hinge to a first side of the ballistic helmet, the first amor plate is configured and positioned to provide ballistic protection; a second armor plate attached by a hinge to a second side of the ballistic helmet, the second armor plate is configured and positioned to provide ballistic protection; and an integrated electronic circuit configured to operate and power electronic devices conductively coupled thereto.

A helmet system comprising a distributed processing system includes a central helmet CPU and multiple subsytem processors. The helmet CPU provides configuration settings to the subsystem processors and receives, from each of the multiple subsystem processors, data derived by the subsystem processor based on one or more sensors located in situ with the subsystem processor. The helmet CPU consolidates the derived data for determining one or more operating conditions of the helmet system and characteristics of an environment surrounding the helmet system.

The disclosure relates to a bone conduction-based Bluetooth wireless riding helmet comprising a helmet body, a regulator at an interior of the helmet body, a brim at a front end of the helmet body, and a drawstring connecting two sides of a bottom of the helmet and the drawstring is fixed on the helmet through a quick release buckle; wherein an interior of the helmet body is provided with a removable bone conductor that is electrically connected with a power system and a control system; wherein the control system is electrically connected with a regulating device on the drawstring. The disclosure has the following beneficial effects. On the bone conduction-based helmet, a bone conduction-based vibrator sound source is embedded on each side of the helmet and perfectly integrated with the helmet, so that sounds can be clearly heard even when both ears of a rider are covered and even when it is used in a noisy environment.

The exemplary embodiments herein provide an assembly for transmitting vibrations to a helmet worn by a user, including an annular element adapted to adhere to an outer surface of the helmet. The exemplary embodiments also include an assembly which rotationally connects with the annular element and comprises a bottom housing having a floor, teeth near the floor which engage with the annular element, and a sidewall extending upwardly around the circumference of the circular base unit. The embodiments further include a top housing having an outer sidewall that fits outside of the sidewall of the bottom housing and a plurality of apertures in a top surface; a pressure transducer placed atop the floor; and a mechanical user interface placed above the PCB and having at least one button which extends upwardly and through one of the apertures on the top surface of the top housing.

A communication accessory may include an ear cup configured to at least one of send and receive an audio communication. The ear cup may be detachably coupleable to a first accessory coupling system configured to couple to a helmet and a second accessory coupling system configured to couple to a headband.
