Product description:

★ radio principle is the high frequency signal from the antenna to the receiver (demodulation) reduction into audio signal， to Headset into sonic.

★ to receive FM broadcast.

A ★ understanding of integrated circuits and electronic components.

■ strengthen children DIY ability; to understand the basic principle of transistor radios to listen to the magic of wiresignal;

■ radio circuit is tuned circuit composed by LC， each with a fixed value corresponds to a tuning loop frequency tuner，radio wave receiving down from the antenna， as long as with the frequency FM radio frequency， generating a high-frequency voltage through it on both ends of the winding can this radio frequency signal， the the signal was sent to the amplifying circuit consists of transistor amplification， a capacitance C articles and the external Headset sound.Turn on the power switch by adjusting the station selector can receive different frequencies of the radio to hear thenews， when the hair， not HERSHEY'S will be the 1 spring terminals receiving antenna to improve Taiwan effect.

The children of parents with children finish the assembly process of learning， heuristic education.

◆ exploration boy is exploration， he is not a simple science， but involves a variety of subjects， such as physics，chemistry， astronomy， mathematics， and its visualization， modeling， standardization. Objective is to commence from the interest， find the children's interest in learning， so as to effectively guide， finally let the children interested inlearning. To feel the real world with the scientific thought of splendid， the virtual world and let the children stay away from computer games.

◆ reminder:

Please note that when using the metal sharp edge. Don't will lead into the household outlet， to prevent the risk of electric shock. In the use of some small accessories products don't let the children under the age of 3 to. Please parent child carefully read the product description instruction before using this product.
