The invention relates to a stereo microphone unit with a first and a second interference tube (110, 120), which are arranged at an angle () to each other and each of which has a first end (111, 121) and a second end (112, 122). The stereo microphone unit has a first and a second microphone capsule (MK1, MK2) for detecting an audio signal. Each of the microphone capsules (MK1, MK2) is provided at an end (112, 122) of the first and second interference tube (110, 120). The microphone unit further has a securing unit (150, 151, 152) for collectively securing the first and second interference tube (110, 120), in particular on a mobile device or on a stand. Furthermore, a sleeve (130) is provided as a windscreen, which is connected to the securing unit (150) and which completely surrounds the first and second interference tube (110, 120).


Patent
Sennheiser | Date: 2017-03-08

The invention relates to a headphone unit, comprising a first and a second ear shell (1). Each ear shell comprises a housing (1a), a peripheral ear cushion (3), and a first electroacoustic reproduction transducer (2) for emitting sound outwardly, which electroacoustic reproduction transducer is arranged in or on the housing of the ear shell (1). The headphone unit has at least one second reproduction transducer (20) for emitting sound in the direction of the ear of the user. The headphone unit has a first operating position, in which the ear shells (1) are placed with the ear cushions (3) on or around an ear. The headphone unit has a second operating position, in which the ear cushions (3) of the first and second ear shells (1) lie against each other such that a closed volume (100) is formed therebetween, which can be used as a resonance chamber for the two first electroacoustic reproduction transducers (2) when the two electroacoustic reproduction transducers (2) are activated in the second operating position. By designing the inner volume as a resonance chamber, outward reproduction into the free field can occur with good quality.

The overall objective of the REProMag project is to develop and validate an innovative, resource-efficient manufacturing route (SDS process) for Rare Earth magnets that allows for the economically efficient production of net-shape magnetic parts with complex structures and geometries, while being 100% waste-free along the whole manufacturing chain. The new Shaping, Debinding and Sintering (SDS) process for Rare Earth magnets is an innovative automated manufacturing route to realise complex 3D- and multilayered parts; resulting in a significant increase in the material efficiency of at least 30% during manufacturing; while at the same time allowing additional geometrical features such as threads, cooling channels, small laminations/segments (e.g. to increase the efficiency of electrical motors) and structural optimisations such as lightweight-structures or the joint-free realisation. As part of the project, the possibility to produce hybrid parts such as an improved moving-coil transducer for headphones, loudspeakers and microphones will be evaluated. The SDS process allows a new level of sustainability in production, as the energy efficiency along the whole manufacturing chain can be increased by more than 30% when compared to conventional production routes. Moreover, the used raw material is 100% recycled and can be again recycled in the same way at the end of the lifetime of the products. In short, the innovative REProMag SDS process has the potential to manufacture complex structures of high quality and productivity with minimum use of material and energy, resulting in significant economic advantages compared to conventional manufacturing. The REProMag project is a highly innovative combination of applied research, technology development and integration, resulting in small-scale prototypes and a closely connected demonstration activity clearly showing the technical feasibility of the REProMag SDS processing route in a near to operational environment.


There is provided a method which makes it possible for a device connected to an electronic video camera to be put into a sleep mode by way of switching off the phantom voltage at the interface for sound and to put it back into the working mode again when the phantom voltage from same reappears. In that case that device can put further devices into a sleep mode by way of a wireless connection and also switch them back into the normal working mode again.
