If the aim is to produce the lowest possible tone in the 400 Hz range, it is best to use a mechanically constructed buzzer.
The principle is very simple. A magnetic field is generated by the coil L1. This moves the so-called iron hammer. The movement is detected in coil L2 and the transistor switches. The oscillating circuit synchronizes and the hammer strikes the membrane evenly, producing a very distinctive snare sound.
