Abstract

The present invention provides a hearing aid having a near field resonant parasitic element, including: a microphone; a signal processor for processing input audio signal to compensate a hearing loss of a user of the hearing aid; a speaker connected to an output of the signal processor for providing a sound signal to the user; a transceiver connected to the signal processor. A circuit system comprises at least one element and/or further electric element in the signal processor, the transceiver, interconnecting transmission lines and an antenna structure, the circuit system extends over an area of a support substrate. The hearing aid also comprises a resonant element within a near field of the circuit system to terminate and dissipate unwanted electromagnetic radiation from at least a part of the area. The resonant element realizes a notch filter filtering the unwanted electromagnetic radiation, and can be positioned outside any signal paths of the circuit system.

Description

technical field [0001] The present invention relates to electronic devices, such as hearing aids and hearing aid accessories, and in particular to devices having resonant elements, such as near field resonant parasitic elements, for filtering unwanted electromagnetic radiation eg from transceiver and antenna elements. Background technique [0002] In the increasing number of electronic devices used worldwide, compliance with Electromagnetic Compatibility (EMC) regulations is required for approval of the device. [0003] Due to factors such as faster clock speeds, co-existence of digital and analog systems, shrinking PCB size, etc., designers face more problems when keeping emitted radiation under the limit. This is especially true where space is a critical factor, such as in the case of handheld terminals, mobile phones or medical implants and devices. Space is often so limited that there is no room for traditional solutions eg with respect to grounding, filtering and shiel...
