Abstract

Um ein System (100) sowie ein Verfahren zum Überprüfen der Phasenlage der von einer Lautsprechereinheit (20a, 20b, 20c, 20d) abgegebenen Schallwellen zu schaffen, durch die ein kosten- und materialsparendes, schnelles und zuverlässiges Überprüfen der Richtigkeit des Anschlusses der Lautsprechereinheit (20a, 20b, 20c, 20d) an ein Audio-Wiedergabegerät (10) ermöglicht wird, wird vorgeschlagen,
- mindestens ein Meßmikrophon (30) zum Aufnehmen mindestens eines von der Lautsprechereinheit (20a, 20b, 20c, 20d) abgegebenen Testtons und
- mindestens eine im Audio-Wiedergabegerät (10) enthaltene Empfängereinheit (12) zum Vergleichen der Phasenlage des von der Empfängereinheit (12) erzeugten Testtons mit der Phasenlage des von der Lautsprechereinheit (20a, 20b, 20c, 20d) abgegebenen sowie vom Meßmikrophon (30) aufgenommenen Testtons
vorzusehen.

In order to provide a system (100) and a method for checking the phase position of the sound waves emitted by a loudspeaker unit (20a, 20b, 20c, 20d), by means of which a cost and material saving, fast and reliable checking of the correctness of the connection of the loudspeaker unit (FIG. 20a, 20b, 20c, 20d) to an audio player (10), it is proposed
at least one measuring microphone (30) for receiving at least one test tone emitted by the loudspeaker unit (20a, 20b, 20c, 20d) and
at least one receiver unit (12) contained in the audio playback device (10) for comparing the phase position of the test tone generated by the receiver unit (12) with the phase position of the test unit (20a, 20b, 20c, 20d) and the measuring microphone (30 ) recorded test tones
provided.
