Abstract (en)
A helmet (1) with noise-reducing system includes a helmet body (11), a central control device (13), a fan unit (14), a microphone (15), an amplifier (16), and a Hall effect sensor (17). The helmet body (11) has an observation portion (112) located corresponding to a windscreen (12). The Hall effect sensor (17) can sense whether or not the windscreen (12) is close to a magnetic element (121) and the observation portion (112) is secured to generate a signal. Then the sensed signal is sent to the central control device to determine and adjust the rotation speed of the fan unit (14), the volume of the microphone (15), the broadcasting volume of the amplifier (16) to provide the noise-reducing effect.
