Ultrasonic microphone enclosure
First Claim
1. An ultrasonic microphone enclosure comprising:
- a housing includinga base,a top cover portion secured to the base,a printed circuit board secured to the top cover portion, the printed circuit board having a top surface and a bottom surface, the top surface of the printed circuit board forming an outer surface of the housing created by the top cover portion and the printed circuit board, the top cover portion, the printed circuit board and the base defining a cavity of the housing, anda port opening formed through the printed circuit board; and
a bottom-port microphone sensor mounted on the bottom surface of the printed circuit board within the cavity of the housing and proximate to the port opening,wherein the port opening provides an acoustic path from outside of the housing to the microphone sensor.

Abstract
An apparatus includes a housing having a printed circuit board having a top surface and a bottom surface. The top surface of the printed circuit board forms an outer surface of the housing. The apparatus further includes a bottom-port microphone sensor mounted on the bottom surface of the printed circuit board. The printed circuit board has a port opening formed therein to provide an acoustic path from outside of the housing to the microphone sensor. A method of detecting ultrasonic signals includes receiving ultrasonic signals within a port opening of a printed circuit board forming part of a surface of a housing, and directing ultrasonic signals to a microphone sensor secured to a printed circuit board through the port of the printed circuit board.
