Abstract
Integrated microphone and antennas include a microphone and an antenna. The microphone includes a housing and an acoustic transducer. The housing defines a cavity and includes a conductive layer. The acoustic transducer is positioned within the cavity and structured to generate an acoustic signal. The antenna is at least partially integrated with the microphone and structured to transmit and receive radio frequency signals. The antenna is structured to utilize the conductive layer of the housing as a radiating element.
Claims20
An integrated microphone and antenna comprising:
- a microphone comprising:
- a housing defining a cavity, the housing comprising a conductive layer;
- and
- an acoustic transducer positioned within the cavity and structured to generate an acoustic signal;
- and
- an antenna at least partially integrated with the microphone and structured to transmit and receive radio frequency signals, the antenna structured to utilize the conductive layer of the housing as a radiating element.
An integrated microphone and antenna comprising:
- a microphone structured to generate an acoustic signal;
- a housing at least partially enclosing the microphone, the housing at least partially formed of a conductive material, the conductive material comprising a radiating element of an antenna structured to transmit radio frequency signals;
- a first conductive path configured to communicate the radio frequency signals between an impedance matching network and the conductive material of the housing;
- a second conductive path configured to communicate acoustic signals between an external interface and a signal processing circuit configured to process the acoustic signal generated by an acoustic transducer, the second conductive path electrically isolated from the first conductive path.
