Intercom Circuit Using LM386 IC | Circuit Diagram The circuit mentioned here is a small easy to build Intercom circuit using one LM386 IC one 2N3904 transistor and few other components. LM386 is a very famous amplifier ICs mostly used by electronics hobbyists in audio circuits.In this circuit the 8 ohms speakers are used for both purposes one as speaker Intercom Using LM386 | Electronics For You Keep in touch with your family members from one room to another and also from outside areas such as the garage, using this intercom circuit for bidirectional communication. The advantage of this circuit is that there is no talk listen switch as many intercoms have. The circuit is built around two low power LM386 audio amplifiers. Fig. Scematic Machine Inside: Intercom Circuit Diagram Lm386 We have so many collections wire wiring diagrams and schematics, possibly including what is you need, such as a discussion of the Intercom Circuit Diagram Lm386.If the images produced less suitable way you can look for it using the search box. Two Station Intercom based on LM386 – Circuit Wiring Diagrams This a two station intercom. It uses two wires to run between each intercom unit. Each is self contained with its own battery, speaker, microphone and amplifier circuit. An LM386 audio power amplifier is used. It is widely available, used a minimum of external parts and is well suited to battery operation. Simple Two Way Intercom Circuit Diagram The complete circuit diagram of this Intercom Project is given below. As you can see the circuit is very simple and can be easily built over a breadboard. The main concept behind the circuit is the use of LM386 audio amplifier which receives the audio signal from microphone, amplifies it and plays it on the speaker. Two Station Intercom based on LM386 Schematic Design This a two station intercom. It uses two wires to run between each intercom unit. Each is self contained with its own battery, speaker, microphone and amplifier circuit. An LM386 audio power amplifier is used. It is widely available, used a minimum of external parts and is well suited to battery operation. Simple portable Audio power amplifier circuit using LM386 IC Here i St@r comes with the simplest mini audio amplifier circuit schematic using LM386 low voltage audio power amplifier IC.This circuit is applicable to power medium sized speakers from a music player that can only drive earphones (lm386 headphone). LM386 Audio Amplifier Circuit Diagram LM386 is a low voltage audio amplifier and frequently used in battery powered music devices like radios, guitars, toys etc.The gain range is 20 to 200, gain is internally set to 20 (without using external component) but can be increased to 200 by using resistor and capacitor between PIN 1 and 8, or just with a capacitor.Voltage gain simply means that Voltage out is 200 times the Voltage IN. Mini intercom circuits using OP Amp IC | ElecCircuit In the figure simple circuit we used two the speaker, The first represents the microphone input. When talking they can hear the speaker output. We make the LM390 audio amplifier IC is small, only 1 3 watts. When a two series circuit, using switch to the choice between speaking and listening, it will be a small intercom. See to Detail in Circuit. intercom – Circuit Wiring Diagrams This circuit uses the speakers both as microphones and as loudspeaker. This intercom is made simple by using only a single amplifier IC LM390 to serve two way communication. This circuit is based on master controlled half duplex operation. With LM390, a 6V battery supply would produce loud enough volume. Here is the schematic diagram of the ...
