1. An electronic fence system comprising:

  • a fence wire buried in a yard along the boundary of a confined area within which a pet may move about freely, and which radiates a radio signal for defining a boundary;

    a transmitter electrically connected to the fence wire and transmitting a boundary radio signal for defining the boundary to the fence wire, the boundary signal including a mode selection signal for selecting a direct shock mode to the pet or a combination shock mode after first producing a sound; and

    a receiver attached to the pet, that receives the boundary radio signal for defining the boundary with respect to a pet'"'"'s approach to the fence wire, and that generates either electrical shock only, or electrical shock and vibration as well as sound depending on the mode selection signal, comprised of a first and a second sensor unit for receiving the boundary radio signal from the fence wire and transforming the boundary radio signal into binary data, a power supplier including a voltage regulator, a recharge battery, and a charger, a power switch for applying power to the power supplier while the user pushes the power switch, a low voltage display for sensing the voltage of the recharge battery and for displaying its low voltage status, a vibration generator for applying a vibration to the pet according to the command of the receiver controller, a sound signal generator for generating a sound according to the command of the receiver controller, a shock generator for giving an electrical shock to the pet according to the command of the receiver controller, a receiver controller for receiving the signal sent from the transmitter through the first and the second sensor, and controlling the respective units for giving either electrical shock only, or a combination of electrical shock and vibration as well as sound or electrical shock and vibration as well as sound depending on the mode selection signal to the pet according to the command of the receiver controller and a power actuator for continually applying power to the power supplier according to a power hold signal received from the receiver controller.
