HEARING AID WITH ANTENNA FOR RECEPTION AND TRANSMISSION OF ELECTROMAGNETIC SIGNALS

摘要

The invention regards a communication device which is adapted for placement in a users ear. The communication device comprises a shell part enclosing an input transducer for receiving an input signal, a signal processing device and an output N transducer for providing a signal perceivable as sound, a battery located at a surface part of the shell which is facing away from the head of the user, a transmission and reception circuit for transmission and/or reception of electromagnetic energy. According to the invention an antenna for radiating and/or receiving electromagnetic energy is provided such that it has a first surface turned towards the surroundings and a second surface located in close proximity of the battery.

主权项

1. Communication device which is adapted for placement in a user's ear and comprises:
an input transducer for receiving an input signal; a signal processing device and an output transducer for providing a signal perceivable as sound; a battery; a transmission and reception circuit for transmission and/or reception of electromagnetic energy; an unbalanced antenna for radiating and/or receiving electromagnetic energy; and a shell part enclosing the input transducer, the signal processing device, the battery, the transmission and reception circuit, and the unbalanced antenna; wherein the battery is located at a surface part of the shell which is facing away from the head of the user; the antenna is disposed on the surface part of the shell which is facing away from the head of the user; and the antenna is arranged such that an outer perimeter of a shape defined by the antenna extends beyond an outer perimeter of a shape defined by a projection of the battery on the surface part of the shell.
