Lautsprecher & Mikrofon

Lautsprecher

KEPO bietet Vollfrequenz- und signalbasierte Lautsprecherlösungen für das Armaturenbrett, Signalaufforderung, kleine Hi-Fi-Anlage, und E-Call im Automobilbereich, Haushaltsgeräte, Intelligentes Audio, und andere Branchen. Aufgrund der großen Bandbreite und des hohen Schalldrucks eignen sich unsere Lautsprecher besonders für Anwendungen in Niederspannungskreisen.

• Angepasster Ton & Produktstruktur
• Akustischer Test & Analyse
• Simulationsexperimente

Mikrofon

KEPO Electronics hat sich der Entwicklung eines High-End-Fahrzeug-Tonabnehmersystems verschrieben, das eine genauere Stimmpositionierung und Schallstrahlerfassung ermöglicht. Zusammen mit dem Rauschunterdrückungssystem wird das Rauschen außerhalb des Strahls unterdrückt, Der aufgenommene Klang wird viel klarer sein.

• A2B-Lösung mit geringer Latenz
• Akustische Simulationsexperimente
• Professionelle schalltote Kammer & Test Ausrüstung
