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.


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.


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.

A casing unit is provided that includes a cylindrical peripheral wall portion of quartz or glass, a cover of metal, and a fixing unit configured to fix the casing unit in or to a housing of a hi-fi tube amplifier. Also provided is a hi-fi audio tube amplifier that includes a plurality of tubes configured to amplify audio signals, and a plurality of the afore-mentioned casing units. Each casing unit encloses one tube of the plurality tubes at three sides, and the fixing unit of each casing unit is configured to fix the respective casing unit in or to a housing of the hi-fi audio tube amplifier.


The invention concerns a transport and/or storage container with integrated charging function for rechargeable wireless earphones comprising a container housing, at least one receiving unit for at least partially receiving a rechargeable wireless earphone, and an electrical container charging contact for connecting the transport and/or storage container to an electrical energy source, wherein the receiving unit has an electrical coupling contact cooperating with an electrical earphone charging contact of a rechargeable wireless earphone when it is placed in the receiving unit for recharging and wherein the electrical container charging contact and the electrical coupling contact are in the form of mutually complementary electrical contacts.


A communication system for communicating a plurality of audio signals between a plurality of control devices, wherein the plurality of control devices comprises at least a subsequent control device and at least a preceding control device. Each control device of the plurality of control devices comprises; an audio port configured to receive a local voice signal of a user of the control device, wherein the local voice signal may be extended into a first local voice signal and a second local voice signal. The control device comprises a primary audio input port configured to receive a first audio signal of the plurality of audio signals transmitted by the subsequent control device, wherein the first audio signal comprises a second voice signal of a second user of the subsequent control device, and a secondary audio input port configured to receive a second audio signal of the plurality of audio signals transmitted by the preceding control device, wherein the second audio signal comprises a third voice signal of a third user of the preceding control device.

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.
