PURPOSE: An electronic device is provided to isolate circuit board assembly from the vibration caused by a frame by installing a plurality of isolator between the circuit board assembly and the frame. CONSTITUTION: An electronic device(100) comprises a frame(106), circuit board assembly(102) and an elastic polymer materials(104-1,104-2,104-3,104-4). The assembly comprises a plurality of circuit boards(108) and is installed in the frame. The elastic material is arranged between the assembly and the frame, is held on a fixed position by the responsive force and the repulsive force, exists between the assembly and the frame in a compression state and exists between the assembly and the frame under tension.
