'loudspeaker' is the definition.
Both the answer and definition are singular nouns.
Maybe you can see an association between them that I don't see?

'local lad kept in charge by outfit's' is the wordplay.
'local' becomes 'pub' (one's local pub).
'kept' means one lot of letters goes inside another.
'in charge' becomes 'ic' (abbreviation for 'in charge').
'by outfit' becomes 'dress' (I've seen this in another clue. I am not sure about the 'by' bit.).
'lad' going around 'ic' is 'licad'.
'pub'+'licad'+'dress'='PUBLIC ADDRESS'
