HEADPHONES
Headphones, with one or two earcups (10), wherein each earcup (10) includes an electroacoustic sound generator (12) having a membrane (13) configured to radiate sound; a rear wall (14), wherein the membrane is arranged between the rear wall (14) and the user’s ear when the headphones are used, wherein a rear side of the membrane (13) faces a rear volume (26) between the membrane (13) and the rear wall (14) and a front side of the membrane (13) faces a front volume (20) between the membrane (13) and the user’s ear; and a tube (18) having a first and a second opening and an inner volume, wherein the tube (18) is arranged between the membrane (13) and the rear wall (14), and wherein the first opening of the tube (18) faces the membrane (13) and the second opening of the tube faces a peripheral environment behind the rear wall (14).
A HEARING DEVICE COMPRISING A CONTROLLABLE VALVE DEVICE AND A METHOD FOR CONTROLLING THE VALVE DEVICE
The disclosure relates to a hearing device comprising a receiver module for insertion into an ear canal of a user of the hearing device, the receiver module comprising a signal processor, an output transducer, and a vent having a valve device, the valve device comprising at least one stationary valve coil, a movable magnet, and a movable valve element, the valve element being configured to open and close the vent, wherein the signal processor is configured to determine a current position of the valve element in the vent, and wherein the signal processor is configured to apply a drive signal to the valve coil to thereby move the valve element from the current position to a desired position. The disclosure further relates to a method for controlling a valve device of a hearing device and a binaural system.
Acoustic devices
The present disclosure provides an acoustic device including a microphone array, a processor, and at least one speaker. The microphone array may be configured to acquire an environmental noise. The processor may be configured to estimate a sound field at a target spatial position using the microphone array. The target spatial position may be closer to an ear canal of a user than each microphone in the microphone array. The processor may be configured to generate a noise reduction signal based on the environmental noise and the sound field estimation of the target spatial position. The at least one speaker may be configured to output a target signal based on the noise reduction signal. The target signal may be used to reduce the environmental noise. The microphone array may be arranged in a target area to minimize an interference signal from the at least one speaker to the microphone array.
