I read a book and the moment was situated in a Tango world championship semifinal as below:<br/><br/>The thought vanished as quickly as it had appeared when the announcer came over the loudspeaker and the crowd erupted to match him.<br/><br/>what doest it mean by "came over"?<br/><br/>I just don't understand when it says "the announcer came over the loudspeaker".<br/><br/>Thanks in advance,
