Description:
FIELD OF THE INVENTION 
     The present invention relates to a specially designed integrated circuit that is able to control and drive another integrated circuit that include voice and motor driving circuits, so as to create desired entertaining effect. 
     BACKGROUND OF THE INVENTION 
     With the highly developed communication technologies, radio communication apparatus, such as pagers, mobile phones, etc., are no longer expensive products and have become very popular among businessmen, general office workers, housewives, students, and even people living in countryside. These radio communication products fully prove the conveniences brought by the high technologies to people in their daily life. 
     The mobile phone becomes increasingly important in the modern society due to its convenience and practicality. While people are enjoying the convenience and efficiency brought to them by the mobile phone, there are still demands for the mobile phone to provide an entertaining effect in addition to its communication function. Inductive electronic products are therefore developed to make the mobile phone versatile in functions and more interesting for use. 
     Most conventional inductive electronic products for such purpose include only a signal receiver for receiving a signal input. The received signal input is then amplified by an amplifier and sent to a driving circuit, so that related driving elements connected to the driving circuit are driven to act and thereby produce entertaining effect. FIG. 1 is a block diagram showing the structure of a conventional inductive electronic device for the above-described purpose. As shown, the conventional inductive electronic device includes an electronic inductive driving circuit  1  that includes a signal induction receiver  12  for inducing and receiving an externally transmitted signal input  11 , an amplifier circuit  13  connected to the signal induction receiver  12  for appropriately amplifying an analogue signal received from the signal induction receiver  12 . 
     The amplifier circuit  13  completes the signal amplification and then outputs an amplified signal to a driving circuit  14 . The driving circuit  14  drives a servo motor  15 , a light-emitting diode  17 , and a speaker  18  connected thereto, so that these servo motor  15 , light-emitting diode  17  and speaker  18  react appropriately in response to received driving signals to create desired entertaining effect. The electronic inductive driving circuit  1  also includes a driving power source  16  for providing power needed by the electronic inductive driving circuit  1  to work. 
     From the above description, it is known that the conventional electronic inductive driving circuit  1  provided on a mobile phone to create entertaining effect is only a signal inducing and amplifying element having a plurality of sound and light producing elements connected thereto. Such conventional electronic inductive driving circuit  1  has not the detection function and is not able to determine whether the signal input  11  is an electromagnetic wave or an interfering wave. Without the detection function, the conventional electronic inductive driving circuit  1  tends to drive driving elements to act even when the received signal input is an unwanted interfering signal, and therefore frequently produces wrong and undesired response to the signal input. 
     It is therefore desirable to improve the conventional electronic inductive driving circuit so that it is wave discriminating to perform its function in a more accurate manner. 
     SUMMARY OF THE INVENTION 
     According to one aspect of the present invention, there is provided a wave-discriminating inductive electronic device that incorporates a detector diode and other elements to screen out unwanted signals, so that an electronic inductive element mounted on a mobile phone enables the mobile phone to provide an optimal entertaining effect without producing wrong and unwanted reactions. 
     According to another aspect of the present invention, there is provided a wave-discriminating inductive electronic device for mounting on a mobile phone.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The present invention relates to a wave-discriminating inductive electronic device that is a consumptive product providing good entertaining effect, and more particularly to a wave-discriminating inductive electronic device that could be induced by a proximity feeble electromagnetic wave produced by a mobile phone or a radio communication apparatus during receiving or transmitting a signal, so as to generate changeful sounds and light beams and thereby increases the entertaining effect provided by the mobile phone or the radio communication apparatus. 
     FIG. 2 is a block diagram of the wave-discriminating inductive electronic device according to an embodiment of the present invention. As shown, there is a signal checking unit  23  being used to check whether a signal input  20  is an electromagnetic-wave signal. The signal input  20  is received by a signal detecting unit  21  that is connected to a switch  22 . The switch  22  performs appropriate transmission of signal depending on the signal received by the signal detecting unit  21 , and drives the signal checking unit  23  and an oscillating unit  24  both being connected to the switch  22 . The signal checking unit  23  is internally set to obtain a predefined sampling signal, which is compared to a data signal output by the signal detecting unit  21  to the signal checking unit  23 . When the data signal output by the signal detecting unit  21  is similar to the predefined sampling signal, a counter  25 , a power driving unit  27 , and a voice driving unit  28  separately connected to the signal checking unit  23  are actuated. The counter  25  is connected to a driving circuit  26  for the latter to perform appropriate work. The power driving unit  27  drives a servo motor  30  connected thereto, so that the servo motor  30  performs appropriate work, such as to produce vibrations. The voice driving unit  28  also drives a speaker  29  connected thereto, so that the speaker  29  produces appropriate voice or sound. 
     When the data signal output by the signal detecting unit  21  does not match with the predefined sampling signal, the data signal is sent to the oscillating unit  24  for a frequency oscillatory response process. The processed data signal is then sent to the signal checking unit  23  again for a second time check by comparing it to the predefined sampling signal again. When the processed data signal still does not match with the predefined sampling signal, it is ignored to avoid wrong and unwanted actuation of the present invention when the signal input is a noise. After the signal input  20  is received by the signal detecting unit  21  and passes a feedback control performed by the signal detecting unit  21  and the signal checking unit  23 , the switch  22  performs appropriate actuation, so that the signal input is transmitted to other appropriate units for appropriate process. The signal checking unit  23  in the above-described circuit constitutes a core of the entire device of the present invention to discriminate whether a signal input is a signal needed by the system of the present invention. When a signal input is determined as an accepted signal, all the related action elements connected to the circuit are enabled to execute different acts, such as flashing and counting on an LED, producing voices or sounds, running a motor, producing vibrations, etc. And, when the signal input is determined as an unaccepted signal, the oscillating unit is immediately stopped and all units for flashing and counting on the LED, producing voices and sounds, running the motor, etc. are immediately disabled. That is, the device of the present invention is adapted to perform immediate detection of signal and to immediately enable various mechanisms, such as LED, voice unit, motor, etc., such that when the signal is removed, these mechanisms could be immediately disabled, and when a new signal is detected, these mechanisms could be immediately enabled. With these arrangements, an interesting and entertaining effect could be created. 
     Please now refer to FIG. 3 that is a block diagram showing the working manner of the circuit of the above-mentioned embodiment of the present invention. As shown, there is a detector diode  4  connected to an integrated circuit  3 . The integrated circuit  3  includes a comparator circuit  31 , a level output circuit  32 , a count driving circuit  33 , and an oscillating circuit  34 . The comparator circuit  31  is configured to perform signal comparison and output any result from the comparison to the level output circuit  32 , the count driving circuit  33  and the oscillating circuit  34 . When the oscillating circuit  34  receives the signal sent by the comparator circuit  31 , it performs an oscillatory process and outputs an oscillating signal to the count driving circuit  33 . Based on the signal received from the comparator circuit  31 , the count driving circuit  33  executes counting and feeds back any result to the comparator circuit  31  for a reference process. The level output circuit  32  receives the signal processed and output by the comparator circuit  31  and outputs a signal to an external driver  5  for the latter to drive a driving unit  6  connected thereto. The driving unit  6  includes driving elements, such as a plurality of light-emitting diodes  61 , a plurality of speakers  62 , and a plurality of servo motors  63 . When the driving elements in the driving unit  6  respond corresponding to the driver  5 , a desired entertaining effect is achieved. 
     The present invention has been described with a preferred embodiment thereof and it is understood that many changes and modifications in the described embodiment can be carried out without departing from the scope and the spirit of the invention that is intended to be limited only by the appended claims.
