The control apparatus further comprises: a first signal generator to provide a first electric probe signal between the first sensor electrode and the reference electrode; a first measurement circuit to determine first signal values in dependence on the impedance between the first sensor electrode and the reference electrode; a detector to recognise gestures in dependence on the first signal values; and a control unit to provide control commands to the hearing device in dependence on recognised gestures. | 2014-05-08 |
20140126760 | WEARABLE SPEAKER SYSTEM WITH SATELLITE SPEAKERS AND A PASSIVE RADIATOR - This application relates to a wearable speaker system with passive radiators and active driver speakers that are connected by tubes. Acoustic energy from each active driver speaker is projected through the tubes to each respective passive radiator, causing the passive radiators to vibrate and resonate in response to the acoustic energy to project the desired audible sounds to a user. | 2014-05-08 |
20140126761 | SPEAKER APPARATUS FOR PRODUCING SOUND - A speaker apparatus for producing sound comprising of a housing, a plurality of covers, a speaker driver, a radiator, a resonator and a resonator stand which in combination provide an enhanced low frequency sound output. | 2014-05-08 |
20140126762 | COMPONENT HAVING A MICROMECHANICAL MICROPHONE STRUCTURE - Measures for dynamically regulating the microphone sensitivity of a MEMS microphone component at low frequencies by way of variable roll-off behavior are proposed. The micromechanical microphone structure of the component, which is implemented in a layer structure on a semiconductor substrate, encompasses an acoustically active diaphragm having leakage openings which spans a sound opening in the substrate back side, and a stationary acoustically permeable counterelement having through openings which is disposed in the layer structure above/below the diaphragm. The component furthermore encompasses a capacitor assemblage for signal sensing, having at least one deflectable electrode on the diaphragm and at least one stationary electrode on the counterelement, and an arrangement for implementing a relative motion between the diaphragm and counterelement parallel to the layer planes. | 2014-05-08 |
