HEARING DEVICE WITH A MEANS FOR RECEIVER CURRENT ESTIMATION AND A METHOD OF ESTIMATING A RECEIVER CURRENT FOR A HEARING DEVICE

摘要

Hearing device has device, for estimating the electric current of consumption, receiver. Hearing devices include signal input means, for input signal to be converted to digital audio and video signals; Signal processing unit, for handling digital audio and video signals, digital-to-analog converter, for handling audio signal from signal processing unit, power amplifier is for amplifying the audio signal converted from digital analog converter, receiver generates hearing devices of the sound from power amplifier and battery-powered according to the audio signal of amplification. In addition,Hearing device of the invention also comprises receiver current estimation device, including filter indicates signal from treated audio signal for filtering receiver electric current, which has frequency response H, and (step f) depends on impedance Z f receivers.
