Audio Circuits
Elektor 301 Circuitspdf contains a variety of audio circuits that you can use to enhance your sound system, create musical instruments, or experiment with sound effects. Here are some examples:
- Simple Audio Amplifier: This is a basic circuit that uses a single transistor to amplify a weak audio signal from a microphone or a line input. It can drive a small speaker or a pair of headphones. You can adjust the volume with a potentiometer and the gain with a resistor. You can also add a capacitor to filter out any DC component in the input signal.
- Sound Level Meter: This is a useful circuit that measures the intensity of sound in decibels (dB) using a microphone and an LED bar graph. The circuit uses an operational amplifier (op-amp) to amplify and rectify the microphone signal, and then feeds it to a comparator network that drives the LEDs according to the voltage level. You can calibrate the circuit with a reference sound source and a potentiometer.
- Theremin: This is a fun circuit that lets you create eerie sounds by waving your hands near two antennas. The circuit uses two oscillators that generate radio frequency signals, one of which is modulated by the capacitance between your hand and one antenna. The other oscillator is fixed and acts as a reference. The difference between the two signals is then demodulated and amplified to produce an audible tone that varies in pitch and volume depending on your hand position.
