The frequency response of the audio transformer is uniform in the operating frequency band. The core is made of a material with high permeability. The primary winding and the secondary winding are tightly coupled, so that the magnetic flux through the primary winding is almost all connected to the secondary winding, and the coupling coefficient is close to 1. The lowest frequency of the passband is determined by the inductance of the primary winding, and the highest frequency is determined by the leakage induction of the transformer.
In order to ensure that the transformer has enough passband, the primary winding inductance should be large, and the leakage inductance should be small.
The hysteresis loss of the core and the saturation of the magnetic circuit will cause the signal distortion. The influence of hysteresis loss can be reduced by rationally allocating load and increasing load current. Increasing the cross section of the core and leaving an air gap can prevent the saturation of the magnetic circuit, thus reducing the distortion of the signal.
