Which of the following is the last link of the audio signal path?

The loudspeaker is the last link in the audio signal path because it is the final component that converts electrical audio signals into audible sound waves that can be heard by the audience. In an audio system, the signal originates from a source, such as a microphone, which captures sound and converts it into an electrical signal. This signal may then go through various processing stages, including amplification and mixing through an audio mixer, to enhance quality and manage multiple audio inputs.

After the signal has been processed, it is sent to an amplifier that increases the power of the audio signal before it reaches the loudspeaker. The function of the loudspeaker is crucial, as it is the point at which the audio is physically outputted into the environment. Therefore, it acts as the concluding element in the audio signal chain, making it pivotal in determining the final audio experience for the listener.
