This sound generator circuit will produce 6 sound effects from the old west and it shows how far integration can be taken: IC1, a Type HT82207 from Holtek does virtually everything. Only a (small) loudspeaker and the necessary selectors need to be added.The standard 18-pin Type HT82207 is an integrated sound generator, producing sounds typical of the Old West. The various sounds are selected by S1 – S6 as listed below. In the quiescent state, the circuit draws a current not exceeding 1 μA.
