Speaker
The word 'altoparlante' is the Italian term for a speaker. It is used in the same context as the English word 'speaker', referring to a device that converts electrical signals into sound. This can be a component of a stereo system, a part of a computer, or a standalone unit. In Italian, 'altoparlante' is a compound word made up of 'alto', meaning 'high', and 'parlante', meaning 'speaking'. So, 'altoparlante' can be literally translated as 'high-speaking', which is a fitting description for a device that projects sound.
