Abstract

The invention discloses a safety helmet which is provided with an MCU (micro control unit), a sound acquisition module, a sound processing module and a loudspeaker, wherein the MCU is used for controlling the sound acquisition module to acquire an environmental sound and transmitting the acquired environmental sound to the sound processing module; the sound processing module is used for linearly amplifying the environmental sound and transmitting the amplified sound to the loudspeaker for playing. According to the safety helmet, a driver can remarkably and clearly hear hoot of surrounding vehicles and other sounds while wearing the helmet for protection and cold prevention, so that the inconvenience due to reduced environmental sound caused by wearing of the safety helmet is avoided, the occurrence rate of traffic accidents is greatly reduced, and the safety driving of the driver is guaranteed.

Description

technical field [0001] The invention relates to a safety helmet, in particular to a safety helmet capable of collecting and transmitting ambient sound and capable of Bluetooth and voice calls. Background technique [0002] With the rapid development of science and technology, the means of transportation for people to travel have become very diversified, and electric vehicles are highly respected by everyone because of their lightness, convenience and environmental protection. But while providing convenience, it often also brings certain troubles to people. Usually, for safety needs, it is necessary to wear a safety helmet when driving an electric vehicle, so as not to hurt the head in the event of a traffic accident. However, when wearing a helmet, such a problem often occurs. The surrounding environment sound becomes smaller, especially the sound of the whistle of the car or other vehicles behind and on both sides. Due to the blocking of the helmet, the sound volume becomes...
