Headphone and headset with an active noise compensation apparatus

摘要

#CMT# #/CMT# A central area (30) of a membrane system (20) curves towards a system (50) of magnets. A sensor microphone (40) picks up noise and fits in a volume between an ear and the curvature area of the membrane system. The central area of the system of magnets is designed as an inverse spherical cap. #CMT# : #/CMT# Independent claims are also included for the following: (1) An active noise-compensating device with a modulator system; (2) A headset with a modulator system; (3) Earphones with a modulator system. #CMT#USE : #/CMT# As a modulator system for an active noise-compensating device with an acoustic playback modulator. #CMT#ADVANTAGE : #/CMT# Clearance between the sensor microphone and the inverse spherical cap is as little as possible without the sensor microphone and the inverse spherical cap touching each other. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a cross-sectional diagram of an active noise-compensating device. 10 : Playback modulator 20 : Membrane system 30 : Central area of membrane system/inverse spherical cap 40 : Sensor microphone 50 : System of magnets.
