    摘要: The present invention relates to a hard hat, comprising: a rigid outer shell, a vibration transducer secured to the exterior of the rigid outer shell, the vibration transducer operative to vibrate the rigid outer shell when active; and a control system coupled to the hard hat, the control system further operably coupled to the vibration transducer such that the control system controls vibration of the vibration transducer. The control system converts received audio communication into a signal sent to the vibration transducer such that activation of the vibration transducer results in vibration of the rigid outer shell, with the rigid outer shell thereby acting as a harmonic resonance acoustic chamber replicating the received audio communication. A kit for converting a hard hat and a method of communication are also disclosed.

    摘要: Headgear includes one or more sensors that provide input information to a controller of the headgear. The sensors may include accelerometers, location sensors, wireless receivers, cameras, and so on. The controller may receive the input information that is indicative of an orientation of the headgear, a location of the headgear, a communication signal, and/or an image or video. The headgear may also include one or more output devices that may be controlled by the controller (e.g., actuators, electronic displays, lights, speakers, and/or communication interfaces). As such, the headgear may output instructions to actuate an actuator, display an image on an electronic display, activate a light, emit a sound using a speaker, and/or send a communication signal using a communication interface. In particular, the headgear may determine an instruction to send to an output device in response to receiving the input information, and send the instruction to the output device.

    摘要: A communication helmet includes a helmet, a fixing belt, and a speaker module. The helmet has a head cavity for protecting a human head. Such helmet may be any known or new types of helmets for protecting soldiers, riders, policemen, working men in architecture building or in another engineering facilities, or for any other purposes and uses. The fixing belt has two belt ends connecting to two sides of the helmet. The fixing belt and the helmet together form a head container for fitting the human head.
