SOUND AMPLIFIER.MJ.SAN.1.

This electronic circuit consists of a housing that contains carefully arranged electronic elements connected in a single circuit. The housing has an important function because it ensures mechanical stability, protection from external influences and a clear organization of components. The right channel of the Bluetooth audio module is connected to the input circuit consisting of series-connected coils and an electrolytic capacitor. Such an input filter allows for preliminary signal processing, its shaping and removal of unwanted interference before being fed to the control electrode of the transistor. The transistor then acts as an amplifier, converting a weak signal into a stronger and more stable one. This ensures reliable operation of the circuit, high efficiency and high-quality preparation of the audio signal for further amplification.
