Embodiment Construction

[0018] In the context of this specification, the following conventions, terms and / or expressions may be used:

[0019] The term "cochlear implant" may denote a device representing the properties of an electromechanical influence, ie electromechanical amplification or electromechanical attenuation, on a received audio signal.

[0020] The term "audio signal" may denote a signal in the form of vibrating air (or more generally, vibrating gas and / or liquid) representing any form of noise or a tone or sequence of tones of varying frequency and amplitude, i.e. having an extended frequency range sound signal. In principle, the concept can also be realized for sound waves in solids. The frequency may be within the receptive range of the human ear, eg 30 Hz to 20 kHz; or it may be an extended range of 25 Hz to 50 kHz, or even a more extended range from 20 Hz to 100 kHz. In general, the concept is not subject to any frequency restrictions.

[0021] The term "microelectromechanical sy...

Abstract

An artificial cochlea device (100, 300) for processing audio signals by electro-mechanical amplitude changes includes a micro-electro- mechanical system, MEMS, microphone (118) comprising a membrane (102), and an electro-mechanical feedback loop (308) embedded in the MEMS microphone. The electro-mechanical feedback loop comprises a piezo-electric actuator (120) mechanically acting on the membrane (102) of the MEMS microphone and configured to alter a mechanical aspect of a mechanical to electrical conversion by the MEMS microphone.

Description

technical field [0001] The present invention relates generally to cochlear implants, and more particularly to cochlear implant devices that process audio signals through electromechanical amplitude changes. The invention also relates to a related method for operating a cochlear implant for processing audio signals by means of electromechanical amplitude changes. Background technique [0002] As computing systems, sensor networks, and robotics become more environment-aware, the greater the need to equip these systems with appropriate sensors. One such category is acoustic sensors that are integrated or connected to processing systems. These are used in, for example, speech recognition, preventive fault monitoring, human machine interface systems, process control systems, ultrasonic detection and analysis, automotive / near field navigation systems, etc. As a reference - especially for simulating the human experience - characteristics of mammalian (eg human) ears may be useful...
