20090022334 | Wire-Free Headset, Portable Media Player - There are proposed wireless headphones which have at least one electroacoustic transducer for the reproduction of audio signals, a receiver for receiving wirelessly transmitted audio data, an intermediate memory for putting the received audio data into intermediate storage, an audio decoding unit and a control unit. The audio data wirelessly received by the receiver are firstly buffered or put into intermediate storage in the intermediate memory. The control unit controls reading of the compressed audio data stored in the intermediate memory so that said data are passed to the audio decoding unit where the compressed audio data are decoded and then outputted by means of the electroacoustic transducers. Wireless transmission is effected at a higher speed than the reproduction of the stored audio signals. | 01-22-2009 |
20090103745 | Headset with Active Noise Compensation - There is provided an earphone comprising an electroacoustic reproduction transducer, a microphone ( | 04-23-2009 |
20090136055 | Converter System for an Active Noise Compensation Apparatus - There is provided a transducer system for an active noise compensation apparatus, which has a first end at the ear side and an electroacoustic transducer. The electroacoustic transducer has a diaphragm system and a magnet system, wherein the central region of the diaphragm system is curved towards the magnet system and is in the form of an inverted calotte. A sensor microphone is arranged in a volume between the first end and the region of the curvature of the diaphragm system. | 05-28-2009 |

20150030173 | Headphone and Headset - A headphone or earphone is provided which includes a housing with an open end and at least one defined dominant acoustic opening, an acoustically sealing earpad arranged at the open end of the housing, and at least one microphone arranged adjacent to common ear or in the vicinity of the dominant acoustical opening for detecting noise. The dominant acoustic opening is arranged within a radius of 2 cm around a midpoint of the at least one microphone. The headphone or earphone also includes an active-noise-compensation unit for performing an active noise compensation based on the output of the microphone and for generating a compensation signal. The headphone or earphone also includes an electro-acoustical transducer inside the housing for reproducing the compensation signal. | 01-29-2015 |
