## Background
CROSS-REFERENCE OF RELATED APPLICATION
This is a continuation-in-part application of a non-provisional application having an application Ser. No. 11/212,990 and a filing date of Aug. 26, 2005 now U.S. Pat. No. 7,405,372.


BACKGROUND OF THE PRESENT INVENTION
1. Field of Invention
The present invention relates to an electronic apparatus, and more particularly to a low powered activation electric device which requires relatively low amperage for activation so as to allow human as a human conductor contacting with two conductive electrodes of an opened electronic circuit to form a closed electronic circuit in a human harmless manner.
2. Description of Related Arts
A conventional switch comprises a lever arranged to operate an electrical device between an “on” position and an “off” position by flicking the lever. An improved switch, which does not require any flicking movement of the lever, is a touch switch. Accordingly, the touch switch is a switch that is turned on and off by touching a wire contact. In comparison with the conventional switch, the touch switch require less mechanical part since the user is able to simply touch a conductor panel of the touch switch for activate the electrical device. However, such touch switch has several drawbacks.
Accordingly, since the touch switch requires the conductor panel contacting with a terminal of the opened circuit to form a closed circuit of the electrical device, an insulating film must be provided between the conductor panel and the terminal to prevent any mis-contact therebetween. Therefore, once the insulating film is worn off after a period of continuous use, the activation operation of the electrical device will be malfunctioned.
In addition, even though the touch switch does not require any flicking movement of the lever, the touch switch requires a slight displacement of the conductor panel to contact with the terminal of the circuit. However, the conductor panel will be eventually mis-aligned with the terminal of the circuit after a period of continuous use. In other words, the reliability of the touch switch will be gradually reduced.
Furthermore, the feeling of touching the conductor panel merely feels as touching a metal plate. Since the conductor panel is made of metal, the conductor panel losses its flexibility and textile feeling. In other words, the inherent feature of the metal plate limits the usage of the conductor panel. Thus, static always occurs at the conductor panel when the conductor is touched by human.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIG. 1 of the drawings, a low powered activation electronic device according to a preferred embodiment of the present invention is illustrated, wherein the low powered activation electronic device comprises a power source 10, and an electronic circuit 20, having two spaced apart electrodes TC+, TC−, electrically connected to the power source 10 to form an opened circuit.
The low powered activation electronic device further comprises two fabric contacts 30 made of textile material provided at the two electrodes TC+, TC− of the electronic circuit 20, wherein the electronic circuit 20 is formed a closed circuit to activate the electronic device in responsive to a physical touch by a human operator at the two fabric contacts 30.
According to a preferred embodiment, the low powered activation electronic device of the present invention is especially designed for children's toy and other related electronic products. Since it requires a relatively low power to activate the electronic circuit 20, even a child is able to operate the electronic device without harming the child when the child touches the fabric contacts 30.
As shown in FIG. 10, the low powered activation electronic device of the present invention is used in the children's toy, such as a doll, having an interior cavity. The power source 10 and the electronic circuit 20 are adapted for being disposed in the interior cavity of the children's toy, wherein the two electrodes TC+, TC− are extended from the electronic circuit 20 within the interior cavity of the children's toy. The two fabric contacts 30 are electrically coupled at the two electrodes TC+, TC− respectively at an outer surface of the children's toy.
For example, the two electrodes TC+, TC− are extended from the electronic circuit 20 and spacedly extended within the doll at two hands thereof while the fabric contacts 30 are integrally provided on the outer surface of the doll at two hand surfaces of the doll to contact with the electrodes TC+, TC− such that when the child touches the fabric contacts 30 of the doll, the electrodes TC+, TC− are electrically connected through the child to form a closed circuit of the electronic circuit 20 so as to activate the electronic device. It is worth to mention that the fabric contacts 30 can be positioned at two feet surfaces of the doll to contact with the electrodes TC+, TC− at two feet of the doll. Likewise, the fabric contacts 30 can be positioned at two ear surfaces of the doll to contact with the electrodes TC+, TC− at two ears of the doll to activate the electronic device when the child touches the ears of the doll. It is worth to mention that when the hands of the child touch the fabric contacts 30, the electrodes TC+, TC− are electrically connected through the child to form a closed circuit of the electronic circuit 20 so as to activate the electronic device. Thus, two or more children, holding their hands with each other, can form a human conductor to form the closed circuit of the electronic circuit 20 when the fabric contacts 30 are touched by the children.
Accordingly, the power source 10 comprises a replaceable battery electrically connected to the electronic circuit 20, wherein the power source 10 is replaceably disposed in the doll such that the power source 10 can be replaced when there is out of battery.

Accordingly, SSF fabrics and other electro-conductive textile materials can be used as primary conduits to complete the opened circuit. But in this case, they are being used as intermediate or secondary electricity conductors. The human operator(s), such as the child, connects the opposite ends of electro-polarities by touching both conductive electrodes covered by SSF fabrics and other electro-conductive textile materials, which serve as the primary conductor to close the opened circuit, thereby activating the electronic device.
The concept of the “human conductor” is not new, Humans are widely capably of being conductors of electric energy. At very low power levels (characterize by low amperage), little or no physical effect will be felt by the human operator as electric energy passes through the human body. However, the combination of 1) Human conductivity, and 2) The utilization of SSF fabrics or other electro-conductive textile materials, 3) The activation, operation, and/or termination of electronic devices, especially in children's toys and other related electronic products. Accordingly, FIGS. 8 and 9 are diagrams elaborating the application of the conductive fabric actually help out shielding off some electro-magnetic-inductance.
In other words, the activation of low powered battery operated electronic device is operated by the human operator(s) touching on both opposite ends of the electrodes covered by the fabric contacts 30 or other electro-conductive textile materials, thereby closing the opened electronic circuit.
