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).

Method and devices for providing surround audio signals are provided. Surround audio signals are received and are binaurally filtered by at least one filter unit. In some embodiments, the input surround audio signals are also processed by at least one equalizing unit. In those embodiments, the binaurally filtered signals and the equalized signals are combined to form output signals.


Patent
Sennheiser | Date: 2016-12-06

There is provided an electroacoustic sound transducer comprising a diaphragm and at least a first and a second coil coupled to the diaphragm so that the first and second coils can vibrate together with the diaphragm. The electroacoustic sound transducer unit has an impedance switching-over unit for connecting together the at least first and second coils to provide a series circuit or a parallel circuit or for contacting the first coil or the second coil.


Patent
Sennheiser | Date: 2016-12-08

Thus there is provided a guitar amplifier microphone unit including at least one microphone capsule having a respective microphone capsule holder and a frame for holding the at least one microphone capsule holder. The at least one microphone capsule holder is arranged displaceably and/or rotatably on the frame.


Patent
Sennheiser | Date: 2017-06-28

A communication system for authenticate a second communication device to a first communication device, wherein the communication system comprises a physical connection between a first communication device and a second communication device, where a first message may be transmitted from the first communication device, via the physical connection, to the second communication device. Furthermore, the communication system comprises a non-physical connection between the first communication device and the second communication device, where a second message may be transmitted from the first communication device, via the non-physical connection, to the second communication device, and wherein the second communication device may be configured to evaluate the first message and the second message based on a matching criteria, and if the evaluation of the first message and the second message fulfills the matching criteria then the second communication device may be configured to transmit an acceptance to the first communication device.


Patent
Sennheiser | Date: 2017-03-10

There is provided an electrodynamic sound transducer having a diaphragm capable of vibrating, a vibrating coil coupled to the diaphragm, and a magnet system. The magnet system has a first and a second magnet ring, which are arranged above and below the diaphragm and are radially magnetized. The vibrating coil is arranged between the first and second magnet rings.


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 invention relates to a wireless pocket transmitter with a rear face (120), a front face (110) and a receiving compartment (101) for a rechargeable battery (200). The receiving compartment (101) has a rear wall (101a), at least part of which forms one part of the rear face, two lateral surfaces (101c) and a connection section (101b) comprising electrical contacts (180). A first side of each of the two lateral surfaces (101c) is coupled to the rear wall and a first end of each is coupled to the connection section (101b). The second end of each lateral surface has a guide (171, 172) for the rechargeable battery. The guides do not extend along the whole length of the lateral surface and the guide has two projections and a passage therebetween.


Patent
Sennheiser | Date: 2017-08-02

The invention relates to an electrodynamic sound transducer comprising a chassis (400, 1400) and at least one vibrating membrane (100, 1100), which comprises, on the edge thereof (1101), at least two securing sections (1101) which are opposite each other and which secure the membrane (100, 1100) to the chassis (400, 1400). Between the securing sections (1101), the edge (1105) of the membrane (100, 1100) is not connected to the chassis (400, 1400) allowing the membrane (100, 1100) to freely vibrate on said points.

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.
