In a loudspeaker unit, the loudspeaker (7) can be inserted into a front plate (1) exhibiting a sound transmission opening (2) via a positively locked locking connection. This should be constructed to be of simple design and to be easily manufactured. The loudspeaker (7) can be centred in the opening (2) and locked in by means of a rotational movement. Particularly intended for a piezoelectric treble speaker in a television receiver.
