Ear terminal with microphone in the meatus, having a filter that provides the characteristics of transmitted signals hblado sound.

摘要

Ear terminal comprising a sealing section (2) arranged for use in the meatus (3) of a human, and comprising an inner microphone (M2) for the ear, having an input sound directed into the meatus (3); and having an outer section (1) to be disposed adjacent the outwardly directed part of the closing section (2); comprising the outer section (1) the inner microphone (M2) and defining the closing section (2) a channel (T1) between the inner microphone (M2) and the sound inlet in the surface of the sealing portion, arranged opposite the auditory meatus; also comprising the outer section (1); an electronic unit (11) including signal processing means (21-26) coupled to said inner microphone (M2) comprising filtering means for filtering the signal from said inner microphone (M2), being programmable said filtering means for transform the signal based on sounds received in the ear by said inner microphone (M2) into equivalent electrical signals having essentially the characteristics of spoken sounds of the user's ear terminal so that the equivalent electrical signals are adapted to be transmitted in digital or analog form to other electronic units and, thereafter, used to present the reconstructed sounds that are desired; and means comprising signal processing (21-26) means for analyzing sounds (21) and selection means (22, E3) to make possible a running classification of the analyzed signal, depending on the corresponding decision for the selection a conditioning filter (23, 24, 25) of the properties of the signal from microphone (M2).
