Zusammenfassung:The utility model discloses a novel dual-band radio controlled clock. The novel dual-band radio controlled clock comprises a dual-band electric wave movement, the dual-band electric wave movement mainly comprises a master control circuit, a receiving circuit connected with the master control circuit and a motor drive circuit. The receiving circuit is mainly provided with a chip U1, an inductor L, crystal oscillators (X1 and X2) and capacitors (C1, C2, C3 and C4). The chip U1 is provided with a control input terminal and a signal output terminal which are connected to a master control circuit, and the chip U1 is further provided with a first crystal oscillator terminal, a second crystal oscillator terminal, a third first crystal oscillator terminal, a first work terminal, a second work terminal and a third work terminal. The crystal oscillator X1 is arranged between the first crystal oscillator terminal and the second crystal oscillator terminal, and the crystal oscillator X2 is arranged between the first crystal oscillator terminal and the third crystal oscillator terminal. The inductor L is parallel with the capacitor C1 and the capacitor C2, then the inductor L, the capacitor C1 and the capacitor C2 are arranged between the first work terminal and the second work terminal, and the capacitor C3 is parallel with the capacitor C4, then the capacitor C3 and the capacitor C4 are arranged between the first work terminal and the third work terminal. The novel dual-band radio controlled clock can work in two frequency modes and automatically select an environmental frequency to work, and the novel dual-band radio controlled clock is convenient to carry and use, diversiform, flexible and reliable.
