Tone/frequency 567 decoder IC (integrated circuit) is not only produce an accurate oscillation, but also delivering a good current handling capability. Up to 100 mA will be safely driven by this single chip oscillator, this means that you don’t need any buffering for most small application.

Precision Oscillator to Switch 100mA Loads circuit schematic diagram

With 100mA, you can drive a small bulb, relay, buzzer, or many other devices. The frequency of this oscillator is inversely proportional to the values of C1 and R1, f=1/(1.1 x R1 x C1). [Circuit's schematic diagram source: Philips Semiconductors Application Note]
