Claim Text:
1. A vibration unit for an acoustic module which comprises a voice coil being induced to reciprocatingly move, wherein said vibration unit comprises: an encircling frame defining a vibration cavity therewithin; a vibration member disposed in said vibration cavity of said encircling frame; and a suspension comprising an elastic diaphragm having an inner edge extended from said vibration member and an outer edge extended to said encircling frame to support said vibration member within said vibration cavity, wherein said inner edge of said diaphragm has a periodically wave-shaped configuration extended from said vibration member to ensure said vibration member to be reciprocatingly moved in a linear direction in response to a movement of said voice coil for sound reproduction, wherein said inner edge of said diaphragm is formed in periodically sinusoid configuration and is defined a plurality of inner edge upper peaks located above a centerline of said vibration member and a plurality of inner edge lower peaks located below said centerline of said vibration member, wherein an amplitude of each of said inner edge upper peaks equals to an amplitude of each of said inner edge lower peaks, wherein said outer edge of said diaphragm is also formed in periodically sinusoid configuration and is defined a plurality of outer edge upper peaks located above a centerline of said encircling frame and a plurality of outer edge lower peaks located below said centerline of said encircling frame, wherein an amplitude of said each of said outer edge upper peaks equals to an amplitude of each of said outer edge lower peaks.
