The difference between sound source input and microphone

1. Different subjects

1. Sound source input: the sound data is generated by the sound source ( sound card) to the power amplifier, headphones, and speakers.

2. Microphone: It is an energy conversion device that converts sound signals into electrical signals.

2. Different sound processing processes

1. Sound source input: The input is processed data, which has become a sound source and can be played.

2. Microphone: The human voice vibrates the diaphragm through the air, and then the electromagnetic coil winding on the diaphragm and the magnet surrounding the moving coil head form a magnetic field cutting, forming a weak fluctuating current. The current is sent to the amplifier, and the reverse process is used to convert the fluctuating current into sound.

3. Different effects

1. Sound source input: It will not cause sound field scattering and directly reaches the output end.

2. Microphone: The microphone will inevitably cause sound field scattering in the sound field.
