Introduction to Audio Output Transformer:

An audio output transformer is a device that converts electronic signals into mechanical vibrations, allowing the signal to be transmitted from an output stage amplifier (power amplifier) to a speaker.

Function of audio output transformer:

quarantine

With the help of an audio output transformer, the input and output are isolated through an insulation layer. This means that the electrical signal flows only in one direction, thereby preventing the output signal from interfering with the input signal.

Suppress noise and interference

Audio output transformers also help suppress interference signals or noise from power sources and other devices, resulting in cleaner and clearer sound output.

impedance matching 

Usually, speakers have lower impedance, while the output circuit of amplifiers has higher impedance. Therefore, transformers are used to match impedance and ensure optimal signal transmission. They provide the correct voltage conversion, allowing the amplifier to transmit signals more effectively to the speaker.

Improve sound quality

By using an audio output transformer, the sound becomes clearer, the bass is richer, and the mid frequency is more natural. This transformer also provides better distortion characteristics and dynamic range.
