Abstract

An electronic device includes a front cover, a circuit board, a plurality of flexible holders, and a plurality of microphones. The front cover includes a plurality of wall portions, a plurality of storage spaces encircled by the wall portions, and a plurality of acoustic openings connecting to the storage spaces. The flexible holders have hollow bodies squeezed into the storage spaces. The microphones are electrically connected to the circuit board and squeezed into the hollow bodies of the flexible holders.

Claims

1. An electronic device, comprising:

a front cover comprising a plurality of wall portions, a plurality of storage spaces encircled by the wall portions, and a plurality of acoustic openings connecting to the storage spaces;

a circuit board;

a flexible holder comprising a plurality of hollow bodies squeezed into the storage spaces, and a base connecting the hollow bodies; and

a plurality of microphones electrically connected to the circuit board and squeezed into the hollow bodies of the flexible holder.

2. The electronic device as claimed in claim 1, wherein the hollow bodies have top holes connected to the acoustic openings of the front cover.

3. The electronic device as claimed in claim 2, wherein the diameter of the top holes exceeds that of the acoustic openings to form cavities between the front cover, the flexible holder, and the microphones.

4. The electronic device as claimed in claim 3, further comprising foam which is disposed in the cavities.

5. The electronic device as claimed in claim 1, wherein the base of the flexible holder is held between the circuit board and the wall portions of the front cover.

6. The electronic device as claimed in claim 1, wherein the hollow bodies have bottom holes through which the microphones are mounted on the circuit board.

7. The electronic device as claimed in claim 6, wherein the microphones are mounted on the circuit board by surface-mount technology.

8. The electronic device as claimed in claim 1, wherein the flexible rubber is made of rubber.

9. The electronic device as claimed in claim 1, wherein the microphones comprise two omni-directional microphones.

10. The electronic device as claimed in claim 1, wherein the microphones constitute a microphone array.

11. The electronic device as claimed in claim 1, wherein the electronic device is a notebook computer.

12. The electronic device as claimed in claim 1, wherein the electronic device is a cellular phone.

13. The electronic device as claimed in claim 1, wherein the electronic device is a personal digital assistant.

14. The electronic device as claimed in claim 1, wherein the electronic device is a global positioning system receiver.

15. The electronic device as claimed in claim 1, wherein the electronic device is a liquid crystal display.

16. The electronic device as claimed in claim 1, wherein the electronic device is a speakerphone.

17. An electronic device, comprising:

a front cover comprising a plurality of wall portions, a plurality of storage spaces encircled by the wall portions, and a plurality of acoustic openings connecting to the storage spaces;

a circuit board;

a plurality of flexible holders comprising hollow bodies squeezed into the storage spaces; and

a plurality of microphones electrically connected to the circuit board and squeezed into the hollow bodies of the flexible holders.

18. The electronic device as claimed in claim 17, wherein the hollow bodies have top holes connected to the acoustic openings.

19. The electronic device as claimed in claim 18, wherein the diameter of the top holes exceeds that of the acoustic openings to form cavities between the front cover, the flexible holders, and the microphones.

20. The electronic device as claimed in claim 19, further comprising foam which is disposed in the cavities.

21. The electronic device as claimed in claim 18, wherein the diameter of the top holes substantially equals that of the acoustic openings.

22. The electronic device as claimed in claim 17, wherein the hollow bodies have bottom holes, and the microphones comprise terminal pins passing through the bottom holes and electrically connecting to the circuit board.

23. The electronic device as claimed in claim 17, wherein the hollow bodies have bottom holes through which the microphones are mounted on the circuit board.

24. The electronic device as claimed in claim 23, wherein the microphones are mounted on the circuit board by surface-mount technology.

25. The electronic device as claimed in claim 17, wherein the wall portions of the front cover contact the circuit board.

26. The electronic device as claimed in claim 17, wherein the wall portions of the front cover are spaced apart from the circuit board.

27. The electronic device as claimed in claim 17, wherein the flexible rubber is made of rubber.

28. The electronic device as claimed in claim 17, wherein the microphones comprise two omni-directional microphones.

29. The electronic device as claimed in claim 17, wherein the microphones constitute a microphone array.

30. The electronic device as claimed in claim 17, wherein the electronic device is a notebook computer.

31. The electronic device as claimed in claim 17, wherein the electronic device is a cellular phone.

32. The electronic device as claimed in claim 17, wherein the electronic device is a personal digital assistant.

33. The electronic device as claimed in claim 17, wherein the electronic device is a global positioning system receiver.

34. The electronic device as claimed in claim 17, wherein the electronic device is a liquid crystal display.

35. The electronic device as claimed in claim 17, wherein the electronic device is a speakerphone.
