Glass spherical speaker

- Glass spherical speaker which needs no processing of glass.
- I used cheap glass bowl sold in DAISO (200 yen) and FOSTEX FE103En full-range speaker unit.
- The dimension of glass bowl has slight individual difference, so this thing is marked as work in progress and mainly for sharing idea.
- You need 3.5 x 8mm tapping screws to fix the baffle to the glass bowl. Rubber bands are necessary to seal between them. Electric wires and connectors are also necessary.
