Acoustic apparatus with side port
First Claim
1. An apparatus, comprising:
- a microphone, the microphone including a base, the base having an inner surface and an outer surface, the inner surface being generally parallel with the outer surface, the base having a port extending from the outer surface to the inner surface, the microphone including a micro electro mechanical system (MEMS) transducer coupled to the inner surface of the base over the port, the microphone having a cover coupled to the base and enclosing the MEMS transducer; and
a gasket coupled to the outer surface of the base, the gasket forming a channel along the outer surface of the base, the channel having a first end and a second end, the first end communicating with the port of the microphone, and the second end of the channel being generally aligned with an edge of the base.

Abstract
An apparatus includes a microphone and a gasket. The microphone includes a base having an inner surface and an outer surface. The inner surface is generally parallel with the outer surface. The base has a port extending from the outer surface to the inner surface. The microphone includes a micro electro mechanical system (MEMS) transducer coupled to the inner surface of the base over the port. The microphone has a cover coupled to the base and the cover encloses the MEMS transducer. The gasket is coupled to the outer surface of the base and forms a channel. The channel has a first end and a second end. The first end communicates with the port of the microphone, and the second end of the channel is generally aligned with an edge of the base.
