Switchgear cabinet for installation of electronic installation components and servers, has sensor acoustically coupled with door to detect vibrations, and vibration generator coupled with door to impress counter-vibrations reducing noise

摘要

The cabinet (1) has a measuring sensor device with a measuring sensor (42) e.g. microphone arrangement, for sound causing vibrations. An active sound-proofing device (40) detects and rejects the vibrations, of a door (12) i.e. sight door. The sensor is acoustically coupled with a door for detecting the vibrations of the door, and a vibration generator (41) i.e. piezoceramic actuator, is coupled with the door for impressing counter-vibration reducing noise. The generator is arranged at interior side of the door and/or of lateral and/or rear side cladding parts e.g. sidewall elements (10, 11).
