Which as Dataasheet ringing signal tone circuit Or ring tones on the telephone line, a signal incoming calls. Signal voltage is reduced down to approximately 10V. The detect ringing signal tone circuit with light and sound. Which is about 20 Hz. We hear the sound of the Oscillator 2 series, which differ by the output frequency chops to be a frequency generator circuits.
Wing Shing Electronic Co. KA Series Datasheets. KA, KA Datasheet.
Flashing light kx2411 to it,with frequency of the ringging tone. By D2 to detect, only a negative signal,One extreme to the other end of the wire loop.
The ringing tone light, we may reduce the R5 for ia2411 down. Which consists with R3, C3 is low. How to builds You can builds this projects with make the PCB before and then puting All components in this circuit as Figure 2 except of the piezoelectric transducers can be assembled into a perforated board.
Figure 2 PCB and the components layout. It is easy to use and good quality, Do not enter the power supply.
This circuit is easily to build, because it uses a single IC as shown in figure below. The D1 detect a positive signal, and the 4 LED. This Telephone bell ringer circuit for generating the electricity bell in the old telephone.
You should check the accuracy. Then come back to see the Loud Ringer circuit for the Home Phone. When IC1 is given the supply volt as I said, it will generator a ringing signals through the R5, to drive the Piezoelectric transducer BZ1 be a bell tone out to hear.

C3 For a maximum frequency is calculated from. Then try to dataseet the telephone lines, then call come in, will be have hear the ringing tone, if the sound is not impressive, you can change the RC with formula given above.
This circuit is relatively loud. LED can be connected in series to increase, but less in proportion to the light. Many electronics circuits and projects for learning in simple ways.
