Latest Patents
One of Ekelid's latest patents is titled "Feedback cancellation with low frequency input." This invention relates to a method for canceling feedback in an acoustic system that includes a microphone, a signal path, a speaker, and means for detecting the presence of feedback. The method utilizes a Least Mean Squares (LMS) algorithm that adapts its speed based on the presence of feedback. Additionally, it incorporates a high-pass filter to prevent low-frequency signals from entering the LMS algorithm. This invention is particularly relevant for hearing aids, where feedback cancellation is crucial for user experience.
Another significant patent is "Electromagnetic feedback reduction in communication device." This invention addresses the issue of feedback caused by electromagnetic interference between an induction coil and an output transducer. The method involves producing an equivalent of the electromagnetic feedback path and subtracting it from the input signal to achieve feedback reduction. The device designed for this method includes an induction coil and filter means to generate the equivalent feedback signal.
