a plurality of internal partitions carried by the baffle enclosure to define a serpentine tuning port therein acoustically coupled between the audio output transducer and the display, and acoustically isolated from the audio output port to also provide the haptic feedback through the display.
2. The electronic device of claim 1 wherein the audio output transducer is directed to an underside of the display.
3. The electronic device of claim 1 wherein the baffle enclosure has a tuning port opening therein.
4. The electronic device of claim 3 wherein the tuning port opening is directed to an underside of the display.
5. The electronic device of claim 4 wherein the audio output transducer is laterally adjacent the tuning port opening.
6. The electronic device of claim 5 further comprising an external partition carried within the housing and outside the baffle enclosure between the audio output transducer and the tuning port opening.
7. The electronic device of claim 1 wherein the baffle enclosure comprises opposing first and second sidewalls; and wherein the plurality of internal partitions extend inwardly from the opposing first and second sidewalls.
8. The electronic device of claim 7 wherein the plurality of internal partitions extend inwardly from the opposing first and second sidewalls in an alternating fashion.
9. The electronic device of claim 1 wherein the plurality of internal partitions are parallel.
10. The electronic device of claim 1 wherein the display comprises a touch-screen display.
11. An electronic device comprising:
a housing having an audio output port therein;
wireless communications circuitry carried by the housing;
a display carried by the housing;
a baffle enclosure carried within the housing;
an audio output transducer carried by the baffle enclosure and acoustically coupled to the audio output port, the audio output transducer being positioned relative to the display to provide haptic feedback through the display;
a plurality of internal partitions carried by the baffle enclosure to define a serpentine tuning port therein acoustically coupled between the audio output transducer and the display, and acoustically isolated from the audio output port to also provide the haptic feedback through the display; and
a controller coupled to the wireless communications circuitry, the display, and the audio output transducer, the controller configured to perform at least one wireless communications function, and selectively operate the audio output transducer to provide the haptic feedback through the display.
12. The electronic device of claim 11 wherein the audio output transducer is directed to an underside of the display.
13. The electronic device of claim 11 wherein the baffle enclosure has a tuning port opening therein.
14. The electronic device of claim 13 wherein the tuning port opening is directed to an underside of the display.
15. The electronic device of claim 14 wherein the audio output transducer is laterally adjacent the tuning port opening.
16. The electronic device of claim 15 further comprising an external partition carried within the housing and outside the baffle enclosure between the audio output transducer and the tuning port opening.
17. A method of making an electronic device comprising a housing having an audio output port therein, and a display carried by the housing, the method comprising:
mounting an audio output transducer on a baffle enclosure;
mounting a plurality of internal partitions to be carried by the baffle enclosure to define a serpentine tuning port therein; and
mounting the baffle enclosure within the housing so that the audio output transducer is acoustically coupled to the audio output port and positioned relative to the display to provide haptic feedback through the display, and so that the serpentine tuning port is between the audio output transducer and the display and acoustically isolated from the audio output port to also provide the haptic feedback through the display.
18. The method of claim 17 wherein mounting the baffle enclosure comprises mounting the baffle enclosure to be directed to an underside of the display.
19. The method of claim 17 wherein mounting the baffle enclosure comprises mounting the baffle enclosure so that a tuning port opening therein is directed to an underside of the display.
