Abstract
A microphone system has a base with at least one electrical port for electrically communicating with an external device. The system also has a solid metal lid coupled to the base to form an internal chamber, and a silicon microphone secured to the lid within the chamber. The lid has an aperture for receiving an audible signal, while the microphone is electrically connected to the electrical port of the base.
Claims28
A microphone system comprising:
- a base having at least one electrical port for electrically communicating with an external device;
- a solid metal lid coupled to the base, the lid and base forming an internal chamber, the lid having at least one aperture for receiving an audible signal;
- and
- a silicon microphone secured to the lid within the chamber, the microphone being electrically connected to the electrical port of the base.
A top port microphone system comprising:
- a package comprising a base coupled with a solid metal lid, the lid and base forming an internal chamber, the lid having at least one aperture for receiving an audible signal;
- and
- a silicon microphone secured to the lid within the chamber, the microphone being connected about at least one aperture.
A method of forming a microphone system, the method comprising:
- providing a solid metal lid with at least one aperture;
- securing the solid metal lid to a base to form an interior chamber;
- and
- securing a silicon microphone about the at least one aperture within the interior chamber.
A microphone system comprising:
- a base having at least one electrical port for electrically communicating with an external device;
- a lid coupled to the base, the lid and base forming an internal chamber;
- a silicon microphone secured to the lid within the chamber;
- an electrical connector extending through the interior chamber to contact the base, the electrical connector electrically connecting the microphone to the electrical port of the base.
The microphone system as defined by claim 26 wherein the bump extends between the microphone and the base.
