Coneless, no-moving-parts speaker

A coneless, no-moving-parts speaker comprising:

• a housing having first and second spaced apart, parallel exterior walls having facing interior side surfaces;
• an annular boss formed on said interior side surface of said first exterior wall;
• a first annular lip formed on an outer peripheral side portion of said annular boss and axially projecting therefrom toward said second exterior wall;
• a second annular lip formed on said interior side surface of said second exterior wall and axially projecting toward said first exterior wall;
• a voice coil disposed on a tubular core portion within said housing, said core portion having a first end fixedly secured to a central portion of said inner side surface of said first exterior wall, and a second end spaced inwardly apart from said interior side surface of said second exterior wall;
• wiring means, connected to said voice coil and extending outwardly through said housing, for transmitting electrical energy from an external source to said voice coil;
• a first annular metal washer member disposed within said housing, said first metal washer member having a peripheral portion closely received by said first annular lip, a first side surface abutting said annular boss and being in a spaced apart, facing relationship with said interior side surface of said first exterior wall, a second side surface facing and being spaced inwardly apart from said interior side surface of said second exterior wall, and being aligned with said second end of said tubular core portion, and a central circular opening outwardly circumscribing said voice coil;
• an annular magnet member disposed within said housing and having a first side surface coaxially and fixedly secured to said second side surface of said first washer member, a central circular opening having a diameter substantially identical with the diameter of said central circular opening of said first washer member, and a second side surface facing and inwardly spaced apart from said interior side surface of said second exterior wall;
• a second annular metal washer member disposed within said housing and having a first side surface coaxially and fixedly secured to said second side surface of said magnet member, a circular central opening, a peripheral portion closely received in said second annular lip, and a second side surface abutting said interior side surface of said second exterior wall;
• and
• a cylindrical metal alignment shaft disposed within said housing and having a first end portion closely received in said tubular core portion, and a radially enlarged second end portion press-fitted into said circular opening in said second washer member, the side surface of said central opening in said magnet member forming with said alignment shaft an annular reverberation chamber extending from said second end of said tubular core portion to said radially enlarged second end portion of said alignment shaft, said alignment shaft having an end surface that abuts said interior side surface of said first exterior housing wall.
