Definitions

  • the present invention relates to a helmet with noise-reducing system, and more specifically, to a helmet with noise-reducing system that can automatically adjust the rotation speed of a fan unit, the volume of a microphone, the broadcasting volume of an amplifier through a Hall effect sensor sensing whether or not a windscreen being close to a magnetic element, so as to achieve the noise-reducing effect.
  • Some full-face helmets are equipped with a cooling fan to cool the hot air thereof. Still, this kind of cooling fan only can be turn on or off by the user but not adjustable. Therefore, it is very likely at the same time the user can be interfered by the loud noisy rotation speed of the cooling fan to miss warning alarms generated by other vehicles, and even in the worse condition, to cause traffic accidents.
  • a primary object of the present invention is to provide a helmet with noise-reducing system that
  • the helmet with noise-reducing system includes a helmet body, a central control device, a fan unit, a microphone, an amplifier, and a Hall effect sensor.
  • the helmet body has a receiving space, an observation portion, a wearing portion, and a windscreen.
  • the observation portion is communicable with the receiving space and the wearing portion.
  • the windscreen is located corresponding to the observation portion when the wind screen is downwardly moved to secure the observation portion.
  • a magnetic element is disposed on a bottom of the observation portion.
  • the central control device has a processing chip and a plurality of circuit units located in the receiving space.
  • the microphone is electrically connected to the processing chip of the central control device via the circuit units and located in the receiving space.
  • the amplifier is electrically connected to the processing chip of the central control device via the circuit units and located in the receiving space.
  • the fan unit 14 is electrically connected to the processing chip of the central control device via the circuit units and located in the receiving space.
  • the Hall effect sensor is located corresponding to the magnetic element when the observation portion is secured, and used for sensing whether or not the magnetic element is close therto to generate a signal. Then the sensed signal is sent to the central control device to determine and adjust the microphone, the amplifier, and the fan unit, so as to achieve the noise-reducing effect.
  • FIG. 1 is block diagram of a helmet with noise-reducing system 1 according to a first preferred embodiment of the present invention
  • Fig. 2 which is a perspective view of the helmet with noise-reducing system according to the first preferred embodiment of the present invention.
  • the helmet with noise-reducing system 1 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 present invention is also briefly referred to as the helmet and generally denoted by reference numeral 1.
  • the helmet body 11 has a receiving space 111, an observation portion 112, a wearing portion 113, and a windscreen 12.
  • the observation portion 112 is communicable with the receiving space 111 and the wearing portion 113.
  • the windscreen 12 is located corresponding to the observation portion 112 when the wind screen 12 is downwardly moved to secure the observation portion 112.
  • a magnetic element 121 is disposed on a bottom of the observation portion 112.
  • a user's head (not shown) is received in the receiving space 111 of the helmet body 11 through the wearing portion 113, and the user's eyes corresponding to the observation portion 112.
  • the central control device 13 has a processing chip 131 and a plurality of circuit units 132 located in the receiving space 111.
  • the microphone 15 is electrically connected to the processing chip 131 of the central control device 13 via the circuit units 132 and located in the receiving space 111.
  • the microphone 15 is used for receiving an external sound signal 151 to generate an external noise signal 152, which is then sent to the processing chip 131 of the central control device 13 to determine whether or not the external noise signal 152 is too noisy. Then the central control device 13 can increase the reception sensitivity of the microphone 15 when the external noise signal 152 is determined too noisy.
  • the amplifier 16 is electrically connected to the processing chip 131 of the central control device 13 via the circuit units 132 and located in the receiving space 111.
  • the amplifier 16 is an earphone or a horn and used for broadcasting a sound signal 161 or a reduced external sound signal 162 outputted by the central control device 13.
  • the fan unit 14 is electrically connected to the processing chip 131 of the central control device 13 via the circuit units 132 and located in the receiving space 111.
  • the fan unit 14 is a cooling fan and has a rotation speed adjusted by the central control unit 13.
  • the Hall effect sensor 17 is located corresponding to the magnetic element 121 when the observation portion 112 is secured, and used for sensing whether or not the magnetic element 121 is close therto to generate a signal. Then the sensed signal is sent to the central control device 13 to determine and adjust the microphone 15, the amplifier 16, and the fan unit 14.
  • the Hall effect sensor 17 can sense whether or not the windscreen 12 is close to the magnetic element 121 and the observation portion 112 is secured to generate a signal. Then the sensed signal is sent to the processing chip 131 of the central control device 13 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.
  • the Hall effect sensor 17 senses whether or not the windscreen 12 is close to the magnetic element 121 and the observation portion 112 is secured to generate a signal.
  • the microphone 15 receives the external sound signal 151 to generate the external noise signal 152, which is then sent to the processing chip 131 of the central control device 13 to determine whether or not the external noise signal 152 is too noisy. Then the central control device 13 can increase the reception sensitivity of the microphone 15 and the volume of the amplifier 16 when the external noise signal 16 is determined too loud. Further, the processing chip 131 of the central control device 13 can output the reduced external sound signal 162 to the amplifier 16 to broadcast to reduce the level of the noisy, so as to achieve the noise-reducing effect.
  • the processing chip 131 of the central control device 13 can adjust and lower the rotation speed of the fan unit 14 and increase the air circulation in the helmet body 11 via the observation portion 112 when the Hall effect sensor 17 is away from the magnetic element 121 and the observation portion 112 is open.
  • the processing chip 131 of the central control device 13 can adjust and lower the reception sensitivity of the microphone 15, the broadcasting volume of the amplifier 16 to prevent the driver from missing warning alarms from other vehicles when the Hall effect sensor 17 is close to the magnetic element 121 and the observation portion 112 is secured.
  • the processing chip 131 of the central control device 13 increases the rotation speed of the fan unit 14 to move the hot air from the receiving space 111 of the helmet 11 into the surrounding air.
  • FIG. 3 is block diagram of the helmet 1 according to a second preferred embodiment of the present invention.
  • the second embodiment of the heat dissipation element 1 is generally structurally similar to the first embodiment except that, in this second embodiment, an antenna device 2 is provided and electrically connected to the central control device 13.
  • the antenna device 2 can be communicated with an external mobile device 3 or a wireless communication device 3, such that the microphone 15 can receive the external sound and the amplifier 16 can broadcast the received sound.
  • Hall effect sensor 17 senses whether or not the windscreen 12 is close to the 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 13 to determine to increase the reception sensitivity of the microphone 15, the broadcasting volume of the amplifier 16 to provide the noise-reducing effect.
