Description of drawings

Accompanying drawing 1 is a remote-control receiving circuit structural drawing of the present utility model.

Accompanying drawing 2 is remote control transmitter circuit structure diagrams of the present utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model circuit structure diagram and the course of work are further described.

As shown in Figure 1, plug J1 is connected with 220V electric main electrical network, and after resistor R 1, capacitor C1 step-down, resistor R 2 current limlitings, D1-D4 rectifier rectification, stabilivolt DW voltage stabilizing, capacitor C 2 filtering, acquisition+5V DC voltage is through K switch 1 control; Integrated circuit block IC1 selects BL8530, little power consumption remote control receiver module for use for the DC/DC transducer and selects for use J04V, decoding integrated circuit piece IC2 to select for use HX2272 and Music Clip to select TR95 for use; The stored electric energy of capacitor C 2 is after integrated circuit block BL8530, inductance L, Xiao Jite diode D5 and capacitor C 3 conversion, and output is stablized the 3V direct current and supplied with little power consumption remote control receiver module J042, decoding integrated circuit piece HX2272 and music integrated circuit block TR950.When remote control transmitter antenna U sends electromagnetic wave signal, remote control receiving antenna E received signal triggers pin 1 end of receiver module J042, deliver to pin 14 ends of demoder through the output of receiver module J042 pin 2 ends, when having only the decoding setting of demoder HX2272 consistent with the encoding setting among the scrambler HX2262, demoder HX2272 pin 17 ends are just exported high level, this level is through resistance R 4, capacitor C 4, music selector switch K2 is added to the trigger end of Music Clip, the Music Clip output end voltage is added to pliotron Q1 base stage through resistor R 5, triode Q1 conducting work, loudspeaker LS sends the musical sound of setting.
