    you need one AVR micro controller like ATMega16

    one IIC based RTC – real time clock

    and two relays – to switch on or off any speaker system

     

    program the RTC as per your requirement. it can give alarm signal similar to normal alarm watch. so you can set alarm as per your convenience like 4 hrs, 5 hrs, 6 hrs etc

     

    to program and control RTC you need AVR micro controller. follow the AVR and RTC tutorials on

    EG labs / micro controllers / AVR on this site

    Thanks for the comments. The purpose for this speaker is to play  some mantras continuosly even without interupting for a second. I want to use it in my house so that my house will continuosly radiate +ve energy. And the house where these mantras are played continously is capable of healing any disease , and the mind of the people living in such a house will remain cool and they will feel happy at every moment.
