WIRELESS HEADPHONES - A SELF-ASSEMBLY KIT

Producer: AVT

Sometimes watching TV is a reason to argue - a loud sound disturbs other household members. Traditional headphones only partially solve this problem - the long cord is uncomfortable. A wireless system is a salvage. In the kit, infrared is used as the transmission medium. The use of frequency modulation allowed for high resistance to interference. A few hours of work with one set of batteries makes the set easy to use. The ability to connect to other sound sources (radio, tape recorder, amplifier) is an argument to complement the equipment of every music lover

The device is especially recommended for viewers who like watching programs broadcast late at night and for those who want to listen carefully to the reader

Selected receiver parameters:

  • a mono system
  • range of operation - within one room
  • carrier frequency of the transmitter - 100 kHz
  • working time on one set of batteries - several hours
  • power supply - 5 V
  • in the set a printed circuit board, a set of elements and documentation
