Telephone bell ringer circuit using IC-KA – ElecCircuit

Many electronics circuits and projects for learning in simple ways. When IC1 is given the supply volt as I said, it will generator a dstasheet signals through the R5, to drive the Piezoelectric transducer BZ1 be a bell tone out to hear.


This circuit is relatively loud. C3 For a maximum frequency is calculated from.

KA 데이터시트(PDF) – List of Unclassifed Manufacturers

It is easy to use and good quality, Do not enter the power supply. Figure 2 PCB dattasheet the components layout. The circuit uses power from the telephone line.

The ringing tone light, we may reduce the R5 for low down. This circuit is easily to build, because it uses dataeheet single IC as shown in figure below. We hear the sound of the Oscillator 2 series, which differ by the output frequency chops to be a frequency generator circuits.

KA2411 Datasheet

Then try to connect 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. Signal voltage is reduced down to approximately 10V. Leave a Reply Cancel ja2411. Which is about 20 Hz.

Which as Detect ringing signal tone circuit Or ka2141 tones on the telephone line, a signal incoming calls. Then come back to see the Loud Ringer circuit for the Home Phone.


The detect ringing signal tone circuit with light and sound. We do not need a new phone. This Telephone bell ringer circuit for generating the electricity bell in the old telephone.

By D2 to detect, only a negative signal,One extreme to the other end of the wire loop.

Which consists with R3, C3 is low. The D1 detect a positive signal, and the 4 LED.

You should check the accuracy. Flashing light attached to it,with frequency of the ringging tone. LED can be connected in series to increase, but less in proportion to the light.
