Abstract

The present disclosure relates to hearing instruments and methods of operating hearing instruments. The hearing instrument includes: a wireless communication unit for wireless communication; a speaker interconnected with the wireless communication unit and configured to provide an output audio signal; a battery configured to power the hearing instrument; a filter circuit interconnected with the battery of the hearing instrument and power management circuitry; the wireless communication unit is interconnected with a battery configured to transmit and receive electromagnetic fields having RF wavelengths. The filter circuit is configured to decouple the battery from the power management circuit at frequencies above 3MHz and is configured to connect the battery to the power management circuit at frequencies below 300kHz.

Description

technical field [0001] The present disclosure relates to a hearing instrument, such as a hearing instrument for compensating for a user's hearing loss, which provides audio to a user, such as an earphone, and in particular to a hearing instrument having wireless communication capabilities, and thus to including a device for communication A hearing instrument with an antenna, and in particular a hearing instrument using a battery of the hearing instrument as at least part of the antenna. Background technique [0002] Over the past few years, hearing instruments of any type have become increasingly capable of communicating with the surrounding environment, including with remote controls, spouse microphones, other hearing instruments, and more recently also directly with smartphones and other external electronic devices. [0003] Hearing instruments are very small and delicate devices, and in order to meet the above requirements, hearing instruments need to include many electro...
