Abstract

A speaker structure includes a first enclosure, a second enclosure, a partition plate and a bass reflex port. The partition plate has a communication hole that is provided between the first enclosure and the second enclosure and allows the first enclosure and the second enclosure to communicate with each other. The bass reflex port is disposed at least on either the first enclosure or the second enclosure.

Claims

1. A speaker structure comprising:

a first enclosure;

a second enclosure;

a partition plate arranged between the first enclosure and the second enclosure, the partition plate including at least one communication hole configured to allow the first enclosure and the second enclosure to communicate with each other; and

a bass reflex port in fluid communication with one or both of the first enclosure and the second enclosure,

wherein the bass reflex port extends across the first enclosure and the second enclosure.

2. The speaker structure according to claim 1, wherein

the bass reflex port is located on a side of the speaker structure away from a front speaker side.

3. The speaker structure according to claim 1, wherein

the base reflex port is located at a rear face side of the first enclosure and the second enclosure, the rear face side being located opposite from a front speaker side of the first enclosure and the second enclosure.

4. The speaker structure according to claim 1, wherein

the bass reflex port has a width along an x-axis extending in a direction that crosses both of the first and second enclosures, the width being greater than a height along a z-axis and greater than a depth along a y-axis, and

the base reflex port longitudinal direction is aligned parallel to a side of the first enclosure and the second enclosure.

5. The speaker structure according to claim 4, wherein

the longitudinal axis of the bass reflex port extends along a direction in which the first enclosure and the second enclosure are arranged in a row.

6. The speaker structure according to claim 1, wherein

a middle region along a longitudinal length of the bass reflex port includes a bent portion.

7. The speaker structure according to claim 6, wherein

the bass reflex port is disposed along an inner wall face of one or both of the first enclosure and the second enclosure.

8. The speaker structure according to claim 1, wherein

the bass reflex port is a one-piece component.

9. The speaker structure according to claim 1, wherein

a wall in one or both of the first enclosure and the second enclosure faces the at least one communication hole.

10. The speaker structure according to claim 9, wherein

the wall protrudes from an inner wall of one or both of the first enclosure and the second enclosure.

14. The speaker structure according to claim 1, wherein

the at least one communication hole is formed in a middle of the partition plate.

15. The speaker structure according to claim 1, wherein

at least portions of the first enclosure, the second enclosure and the partition plate are formed integrally.

16. The speaker structure according to claim 1, comprising:

the at least one communication hole is a plurality of communication holes.

19. The speaker structure according to claim 1, comprising:

the at least one communication hole is a plurality of communication holes.

11. A speaker structure comprising:

a first enclosure;

a second enclosure;

a partition plate arranged between the first enclosure and the second enclosure, the partition plate including at least one communication hole configured to allow the first enclosure and the second enclosure to communicate with each other; and

a bass reflex port in fluid communication with one or both of the first enclosure and the second enclosure, wherein

a wall in one or both of the first enclosure and the second enclosure faces the at least one communication hole,

the wall protrudes from an inner wall of one or both of the first enclosure and the second enclosure, and

the wall protrudes from the partition plate.

12. The speaker structure according to claim 11, wherein

the wall protrudes from a plurality of portions of the partition plate.

17. The speaker structure according to claim 11, wherein

the at least one communication hole is formed in a middle of the partition plate.

18. The speaker structure according to claim 11, wherein

at least portions of the first enclosure, the second enclosure and the partition plate are formed integrally.

13. A speaker structure comprising:

a first enclosure;

a second enclosure;

a partition plate arranged between the first enclosure and the second enclosure, the partition plate including at least one communication hole configured to allow the first enclosure and the second enclosure to communicate with each other; and

a bass reflex port in fluid communication with one or both of the first enclosure and the second enclosure, wherein

a wall in one or both of the first enclosure and the second enclosure faces the at least one communication hole, and

a sound absorbing material is disposed between the wall and the at least one communication hole.
