The audio circuit board is an important component of audio equipment such as speakers and power amplifiers. It can strengthen, filter, and amplify electrical signals to provide necessary electrical conditions for the transmission of music. However, for many people, the structure and components of an audio circuit board remain a mystery. So, what electronic components does the audio circuit board consist of? Below, we will introduce one by one.

Resistor

A resistor is a component whose function is to block the flow of current or change the size of the current in a circuit, which is very important for controlling the output level of an audio amplifier. There are many types of resistors in audio circuit boards, including ordinary resistors, variable resistors, potentiometers, etc. Their resistance values and powers are also different and should be configured appropriately according to different needs.

Capacitor

Capacitors are another common component that store electrical charge and filter the flow of electricity in a circuit. The capacitors in audio circuit boards are mostly aluminum electrolytic capacitors, ceramic capacitors, polyester film capacitors, etc. Different types of capacitors have different characteristics and need to be selected according to the needs of the audio circuit.

Transistors and diodes

A transistor is a semiconductor component whose function is to amplify current, control current, and combine with other components to form a specific circuit. In audio circuits, triodes are usually used in power amplifier circuits, mixer input circuits, etc. Diodes are used in power supply filtering, detection and other aspects.

Transistor

A transistor is a complex semiconductor component whose functions include amplifying current, controlling current, and converting current into energy output in the form of light, sound, heat, etc. In audio circuits, transistors are widely used in amplifier circuits, filter circuits, relay drive circuits, etc.

IC chip

An IC chip is a micro device based on semiconductor technology that can integrate complex circuits and functions. In audio circuits, IC chips are usually used in functional modules such as mixers, power amplifiers, and signal processors to achieve efficient and precise control and processing.

Inductor

Inductor is a component whose function is to store electromagnetic energy in the power supply, hinder the transmission of radio frequency signals, filter and drive signals, etc. In audio circuits, inductors are usually used in power amplifiers, power supply filtering, speaker crossover audio, etc.
