In accordance with the present disclosure a hearing instrument is provided. The hearing instrument comprises a wireless communication unit for wireless communication, a speaker interconnected with the wireless communication unit and being configured to provide an output audio signal, a battery configured to supply power to the hearing instrument, a filter circuit interconnecting the battery and a power management circuit of the hearing instrument, the wireless communication unit being interconnected with the battery, the battery being configured for emission and reception of an electromagnetic field having an RF wavelength. The filter circuit is configured to de-couple the battery and the power management circuit at frequencies above 3 MHz and configured to connect the battery to the power management circuit at frequencies below 300 kHz.

Hearing instrument comprising a battery antenna

A hearing instrument comprises a wireless communication unit interconnected with an antenna for emission and reception of an electromagnetic field having an RF wavelength, a speaker interconnected with the wireless communication unit and being configured to provide an output audio signal. A battery is configured to supply power to the hearing instrument and a filter circuit interconnects the battery and a power management circuit of the hearing instrument. The antenna extends from a feed and at least a part of the antenna being is arranged adjacent the battery. A distance between the at least part of the antenna and the battery is below 1/40 of the wavelength. The filter circuit is configured to de-couple the battery and the power management circuit at frequencies above 3 MHz and configured to connect the battery to the power management circuit at frequencies below 300 kHz.

Hearing instrument comprising a parasitic battery antenna element

An in-the-ear hearing device includes: a microphone configured to receive an audio signal; a signal processor configured to process the audio signal for compensating a hearing loss; a wireless communication unit being connected to the signal processor; a feeding network; a hearing device shell accommodating the microphone and the signal processor; a face plate positioned at the hearing device shell; and an antenna for electromagnetic field emission and electromagnetic field reception, the antenna coupled with the wireless communications unit, wherein the antenna has a first end, and wherein the feeding network is configured to feed the antenna via the first end of the antenna; wherein the antenna extends through the face plate at a first position; at least a part of the antenna extending from the faceplate being arch-shaped; and wherein a second end of the antenna is an electrically open end, or is coupled to a ground potential.

Hearing device with antenna extending from the hearing device

A hearing instrument includes: a microphone; a signal processor configured to compensating a hearing loss of a user; a speaker configured to provide an output sound signal; a wireless communication unit comprising an oscillator circuitry, the oscillator circuitry having an antenna resonator configured to emit an electromagnetic field at a first frequency and a driving circuit configured to provide a driving circuit output; the driving circuit output comprising: a first sequence of pulses having a first phase and a first pulse width, and a second sequence of pulses having a second phase and a second pulse width, the second phase being phase shifted with respect to the first phase, the first phase and the second phase being based on the first frequency; the oscillator circuitry being configured to obtain the first sequence of pulses and the second sequence of pulses for excitation of the antenna resonator.
