Fig. 2 is pressure generating set principle schematic of the present invention;
In the drawings, key 1, housing 2, piezoelectric patches 3, pressure generating set 4, octave rank electronic organ pronunciation device 5, loudspeaker 6.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is described in detail, but does not constitute the limit to scope
System.
As it is shown in figure 1, be the stereo transparent structural representation of the present invention, as seen from the figure, it includes key 1, housing 2, pressure
Electricity sheet 3, pressure generating set 4, octave rank electronic organ pronunciation device 5 and loudspeaker 6, wherein, key 1, housing 2 and octave rank electronics
Qin pronunciation device 5 and loudspeaker 6 are prior art and product;Octave rank electronic organ pronunciation device 5 includes power supply input circuit, just
String wave oscillator and audio-frequency power amplifier, audio frequency is broadcasted by loudspeaker 6 reduction.Piezoelectric patches 3, pressure generating set 4, octave rank
Electronic organ pronunciation device 5 and loudspeaker 6 are placed in housing 2.Key 1 is placed in above housing 2, is designed with below each key 1
One piece of piezoelectric patches 3, the voltage output end of piezoelectric patches 3 is all connected with the bridge rectifier input of pressure generating set 4.Work as bullet
When pressing key 1 under qin, below key 1, press piezoelectric patches 3, make piezoelectric patches 3 deformation produce voltage and be transported to by wire
The rectification input of pressure generating set 4.Described piezoelectric patches 3 uses piezoelectric ceramic piece, easy to install.
As in figure 2 it is shown, be pressure generating set principle schematic of the present invention, as seen from the figure, the rectification of pressure generating set 4
Input is exactly the electric signal input end of bridge rectifier.And the bridge rectifier of pressure generating set 4, filter circuit,
Voltage detecting circuit, on-off circuit, mu balanced circuit, charging circuit and accumulator are for sequentially to connect, and the signal of telecommunication of input is the most sequentially
Processing, operation principle is:
Playing the musical instrument when pressing key 1, press piezoelectric patches 3 below key 1, piezoelectric patches 3 is produced deformation, is produced by direct piezoelectric effect
Raw electricity.Every piece of piezo-electric generating sheet 3 is all connected with the electric signal input end of bridge rectifier, the voltage produced by piezoelectric patches 3
It is transformed to DC voltage U1.Electric capacity C1 in filter circuit is for the ripple filtered off after rectification in output voltage U1.Voltage detecting
Circuit is made up of with voltage checking chip ME2802, when voltage checking chip ME2802 detects R1 two resistance R1, the R2 concatenated
And the branch pressure voltage Vin between R2 less than its internal reference voltage time, voltage checking chip ME2802 output voltage Vout is
Low level, the base stage of the audion VT1 of on-off circuit and emitter voltage, less than the conduction voltage drop of PN joint, make audion VT1 cut
Only, the relay K dead electricity not adhesive being serially connected on colelctor electrode, contact K1 disconnects, service interruption;When voltage checking chip ME2802
Detecting that branch pressure voltage reaches reference voltage, voltage checking chip ME2802 output voltage Vout is high level, makes on-off circuit
Audion VT1 conducting, relay K obtains electric adhesive, and contact K1 closes, line conduction.Wherein, on-off circuit is by base resistance
R3, audion VT1, diode D1 and relay K and contact K1 composition thereof.Through overvoltage detection circuit and the voltage of on-off circuit
Meet the input requirements of mu balanced circuit, the DC constant voltage U2 that mu balanced circuit output is stable.Mu balanced circuit is mainly by voltage stabilizing core
Sheet HT7150 and electric capacity C2 is constituted.Charging circuit is by charging circuit chip TP4056, resistance R4, R5, R6, R7, R8, R9, electric capacity
C3, C4 and common-anode red green diode D2, D3 composition.DC constant voltage U2 through overcharge circuit constant current charging mode and
Constant-voltage charge pattern is charged to recharged battery E, and recharged battery E is pronounced by current-limiting resistance R10 supply octave rank electronic organ
Device 7 and loudspeaker 8 electric energy, make electronic organ can send various sound.Described recharged battery E uses lithium battery, discharge and recharge is quick,
Stable.
The present invention utilizes the piezoelectric effect of piezoelectric to provide power supply for electronic organ, and the mechanical energy that will act on key 1 turns
Turn to electric energy, through the bridge rectifier of pressure generating set 4, filter circuit, voltage detecting circuit, on-off circuit, voltage stabilizing electricity
Road and charging circuit, and in charging accumulator, stored supply electronic organ uses as power supply, and pressure generating set 4
