Competition Circuit Diagram

Competition Circuit Diagram In a hearing aid circuit, Solder the Lm386 Amplifier to the circuit board or place it on the breadboard. Follow the pin configuration provided in the amplifier's datasheet. you can create a customized hearing aid that suits your specific needs. However, it is essential to remember that a DIY hearing aid should not be considered a

Competition Circuit Diagram

By using capacitor C7, it lowers the gain in the high-frequency band.T to keep the circuit stable while reducing noise, Headphones are directly linked to the power supply and get the audio signal from the collector. Thus, the headphone is a load of this circuit. Application Uses. Hearing aid devices.

Full Circuit Diagram WIth Explaination

The making of the hearing aid is also very simple and would not take more than an hour. The output of the device is a little cracky due to the crude op amp used but for the cost it is made (that is less than 1$) the device is very appreciable. This circuit is a simple hearing aid circuit which is powered with 1.5V battery the working of this circuit is mentioned below. The electret microphone picks up sound waves and converts them into a small voltage signal. Transistor T1 BC547 amplifies this weak signal. Resistor R3 330k and capacitor C2 10uF set the bias point for T1.
