An equipment capable of converting electrical signal into audio signal is called

Explanation:
Converting an electrical signal into audible sound is done by a speaker. It acts as a transducer, turning electrical energy from an amplifier into mechanical motion of a diaphragm, which creates sound waves we hear. The microphone does the opposite, transforming sound into an electrical signal. A transmitter changes an electrical signal into radio waves for transmission, while a receiver converts incoming radio waves back into electrical signals that are typically fed to a speaker to be heard. So the device that directly outputs audio from an electrical signal is the speaker.
