Thanks for the answer!
Sorry but I didn't understand how to use QgsSimpleMarkerSymbolLayerV2.
I did some attempt but I didn't manage..
Below there's my code (with only two symbol item as example)
myTargetField = field
myRangeList = []
myOpacity = 1
# symbol 1
mySymbol = QgsSymbolV2.defaultSymbol(layer.geometryType())
mySymbol.setColor(QColor('#FFFFFF'))
mySymbol.setAlpha(myOpacity)
myRange = QgsRendererRangeV2(0.1,34.4,mySymbol,"< 35")
myRangeList.append(myRange)
# symbol 2
mySymbol = QgsSymbolV2.defaultSymbol(layer.geometryType())
mySymbol.setColor(QColor('#238443'))
mySymbol.setAlpha(myOpacity)
myRange = QgsRendererRangeV2(34.5,39.4,mySymbol,"35 - 39 dB(A)")
myRangeList.append(myRange)
# other symbol items
myRenderer = QgsGraduatedSymbolRendererV2('', myRangeList)
myRenderer.setMode(QgsGraduatedSymbolRendererV2.EqualInterval)
myRenderer.setClassAttribute(myTargetField)
layer.setRendererV2(myRenderer)
iface.legendInterface().refreshLayerSymbology(layer)
layer.triggerRepaint()
And I want that symbol 1 became a square.
I can't understand how to use QgsSimpleMarkerSymbolLayerV2.
Sorry and thank you!

after having got the symbol layer (QgsSimpleMarkerSymbolLayerV2) you
can use the setName() method to change from circle (default) to any
other symbol. In your case setName("square").
