It can work at up to 32V DC. The first op-amp A1 is wired as a low-frequency squarewave generator. Op-amp A2 works as an integrator, while op-amp A3 works as a comparator. Op-amp A4 is wired as a buffer and its output provides base current to npn transistor T2.

When power is switched on, a basic tone is generated by transistor T2 and transformer X1, which is frequency-modulated by the wandering voltage generator, which, in turn, is influenced by the low-frequency squarewave generator. The circuit works off regulated 9V.
