摘要:
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.

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.
摘要:
Es wird ein digitales Drahtlos-Audioübertragungssystem, insbesondere ein Drahtlos-Mikrofon- oder Drahtlos-Taschensender-System vorgesehen. Das Audioübertragungssystem weist mindestens einen Drahtlos-Sender (S) und einen Drahtlos-Empfänger (E) auf. Der Drahtlos-Sender (S) weist einen analogen Eingang (AI), ein digital einstellbares Eingangspotentiometer (DCPI) zum Einstellen der Eingangsverstärkung, einen Analog/Digital-Wandler (ADC) zum Wandeln der analogen Signale in digitale Signale, eine digitale Signalverarbeitungseinheit (DSP) zum Durchführen einer digitalen Signalverarbeitung und ein digitales (DP) oder ein digital einstellbares Ausgangspotentiometer (DCPO) zum Einstellen der Ausgangsverstärkung auf. Die digitale Signalverarbeitungseinheit (DSP) ist dazu ausgestaltet, die Verstärkung des digitalen Eingangspotentiometers (DCPI) und/oder des digitalen Ausgangspotentiometers (DCPO) derart einzustellen, dass der dynamische Bereich des Analog/Digital-Wandlers (ADC) optimal genutzt wird.
摘要:
A headphone is provided which comprises 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, wherein 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 comprises 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 comprises an electro-acoustical transducer inside the housing for reproducing the compensation signal.
