Claim Text:
1. An acoustic module, comprising: at least a first acoustic unit defining a first chamber; at least a second acoustic unit defining a second chamber, wherein each of said first and second acoustic units comprises a frame, a vibration member, and a suspension provided around said vibration member and is located between said vibration member and said frame to enable said vibration member to be reciprocatingly moved, wherein said first chamber and said second chamber combine and share to form a common air sealing chamber that a depth of said first chamber equals to a depth of said second chamber, such that when said vibration member of said first acoustic unit is reciprocatingly moved, said vibration member of said second acoustic unit is driven to reciprocatingly move by means of shifting air pressure through said common air sealing chamber; and an acoustic enclosure coupled with said frames to enclose said common air sealing chamber, wherein a height of said acoustic enclosure is the same as a depth of said common air sealing chamber.
