4. The system as claimed in claim 1 , further comprising:
a gasket located on a top of the enclosure;
a cap for the gasket; and
a second aperture on a top surface of the enclosure,
wherein the cap, the gasket and the top of the enclosure define a second volume connected to the first volume by the second aperture.
5. The system as claimed in claim 1 , wherein the housing further comprises a mounting region extending from an internal surface to hold the speaker.
6. The system as claimed in claim 1 , wherein the speaker is a back speaker projecting sound from a back side of the electronic device.
7. The system as claimed in claim 6 , wherein the first volume is between 0.3 cm 3 and 5.0 cm 3 .
8. The system as claimed in claim 1 , wherein the first aperture has a cross-sectional area of between 0.1 mm2 and 20 mm2 on the substrate.
9. The system as claimed in claim 1 , further comprising a tube inserted into the first aperture.
10. The system as claimed in claim 1 , wherein:
the enclosure encloses an antenna for an electronic device.
11. An electronic device, comprising:
a housing;
a substrate having
a first side with a speaker mounted on the first side,
a second side opposite the first side, and
a first aperture providing an opening from the first side to the second side of the substrate;
the speaker making an electrical connection with the first side of the substrate;
a component mounted on the second side of the substrate opposite the speaker; and
an enclosure
affixed to the substrate on the second side; and
covering and providing a radio frequency ‘RF’ shield for the component on the second side of the substrate,
wherein
the substrate, the speaker and the enclosure are contained within the housing; and
a first volume is defined by an interior space defined by the enclosure, the component and the second side of the substrate.
12. The electronic device as claimed in claim 11 , further comprising:
a second speaker,
wherein the speaker is a back speaker projecting sound from a back side of the electronic device.
13. The electronic device as claimed in claim 11 , further comprising:
a gasket located on a top of the enclosure; and
a second aperture on a top surface of the enclosure,
wherein the housing, the gasket and the top of the enclosure define a second volume connected to the first volume by the second aperture.
14. The electronic device as claimed in claim 11 , wherein the housing further comprises a mounting region extending from an internal surface to hold the speaker.
15. The electronic device as claimed in claim 11 , wherein the first volume is between 0.3 cm 3 and 5.0 cm 3 .
16. The electronic device as claimed in claim 11 , wherein the first aperture has a cross-sectional area of between 0.1 mm2 and 20 mm2 on the substrate.
