Hearing aid having combined antennas
A hearing aid having a hearing aid housing, includes: a microphone; a processing unit configured to process an audio signal for compensating a hearing loss of a user; a battery provided closer to a second end of the hearing aid housing than to a first end of the hearing aid housing; one or more wireless communication units for wireless communication; at least a part of a first antenna for electromagnetic field emission and/or electromagnetic field reception, the at least a part of the first antenna being interconnected with one of the one or more wireless communication units; and a second antenna for electromagnetic field emission and/or electromagnetic field reception, the second antenna being interconnected with one of the one or more wireless communication units; wherein the second antenna is between a center axis of the battery and the second end of the hearing aid.
1. A hearing aid having a hearing aid housing, the hearing aid housing having a first end and a second end, the hearing aid comprising:
a microphone configured to receive an audio signal;
a processing unit configured to process the audio signal for compensating a hearing loss of a user;
a battery provided closer to the second end of the hearing aid housing than to the first end of the hearing aid housing;
one or more wireless communication units for wireless communication;
a first antenna, at least a part of the first antenna for electromagnetic field emission and/or electromagnetic field reception, the at least a part of the first antenna being interconnected with one of the one or more wireless communication units; and
a second antenna for electromagnetic field emission and/or electromagnetic field reception, the second antenna being interconnected with one of the one or more wireless communication units;
wherein the hearing aid housing is configured for accommodation of the microphone, the processing unit, and the one or more wireless communication units; and
wherein the second antenna is located between a center axis of the battery and the second end of the hearing aid housing.
2. The hearing aid according to claim 1 , further comprising:
