Abstract

A speaker box with side acoustic emission structure is disclosed. The speaker box has a case having an acoustic window, a speaker unit mounted in the case and including a diaphragm, a voice coil and a magnetic circuit, the diaphragm disposed in the side of the acoustic window and not faced to the acoustic window and having a dome and a suspension surrounding the dome, the suspension comprising a first end close to the acoustic window and a second end away from the acoustic window, and the first end is lower than the second end along the vibrating direction.

First claim

What is claimed is:

1 . A speaker box, comprising:
a case having a bottom wall, a sidewall extending upwardly and perpendicularly form the bottom wall, and an acoustic window formed in the sidewall; a speaker unit mounted in the case and having a diaphragm positioned below the bottom wall of the case for forming an acoustic passage communicating with the acoustic window, a voice coil, and a magnetic circuit for driving the diaphragm to vibrate along a vibrating direction; the diaphragm having a dome and a suspension surrounding the dome, the suspension comprising a first end close to the acoustic window and a second end away from the acoustic window, and the first end is lower than the second end along the vibrating direction.

2 . The speaker box as claimed in claim 1 , wherein the dome is lower than the first end and the second end along the vibrating direction.

3 . The speaker box as claimed in claim 2 , wherein the dome is a flat board.

4 . A speaker box, comprising:
a cabinet having an acoustic window with a side acoustic emission structure; a speaker unit mounted in the cabinet and including a diaphragm, a voice coil and a magnetic circuit for driving the diaphragm to vibrate along a vibrating direction; the diaphragm disposed in the side of the acoustic window and not faced to the acoustic window, the diaphragm having a dome and a suspension surrounding the dome, the suspension comprising a first end close to the acoustic window and a second end away from the acoustic window, and the first end, is lower than the second end along the vibrating direction.

5 . The speaker box as claimed in claim 4 , wherein the cabinet includes a case and a cover, the case having a bottom wall and a sidewall extending upwardly and perpendicularly form the bottom wall, and the acoustic window is formed in the sidewall.

6 . The speaker box as claimed in claim 5 , wherein the diaphragm is positioned below the bottom wall of the case for forming an acoustic passage for communicating with the acoustic window.

7 . The speaker box as claimed in claim 6 , wherein the case is assembled with the cover to form a receiving space for receiving the speaker unit through interference fitting.

8 . The speaker box as claimed in claim 7 , wherein the speaker box also comprises a PCB board electrically connected with the speaker unit and extending out of the receiving space.

9 . The speaker box as claimed in claim 8 , wherein, the lower plate comprises a slot for the PCB board to extend outwards from the receiving space.
