i think
1- your circuit continusly consume power.
2- you use resistor (lamp) to limit current. (as opposed you mentioned)
3- selection battery voltage and buzzer [trigger]voltage and lamp spec. tightly depend to each other.
4- when battery goes to decharged. your circuit may fail to do anything.
Am i right?

1- your circuit continusly consume power. Yes
2- you use resistor (lamp) to limit current. (as opposed you mentioned) It is NOT a fixed value resistor.
3- selection battery voltage and buzzer [trigger]voltage and lamp spec. tightly depend to each other. Not necessary
4- when battery goes to decharged. your circuit may fail to do anything. It could be another DC source as nothing said the battery should last forever.
Am i right?
In first post you said, you know 2 method for making this circuit can you give us 2nd circuit.If you think really hard, you can do it with 5 extra parts. If you think smart, you will need only
3 (I know of two different ways with 3 extra components, there may be more ways)
2- you use resistor (lamp) to limit current. (as opposed you mentioned) It is NOT a fixed value resistor.
3- selection battery voltage and buzzer [trigger]voltage and lamp spec. tightly depend to each other. Not necessary [/red]
