Capacitive sound generator and capacitive speaker |
| abstract |
Provided is a technique capable of reducing the driving voltage of a capacitive sound wave generator or a capacitive speaker and suppressing power consumption. A fixed electrode 11 having a plate-like shape and having one or a plurality of through-holes 11a provided so as to penetrate in the thickness direction, and having a plate-like or film-like shape, the fixed electrode 11 The two vibrating electrodes 12 are arranged through the through-hole 11a and the two vibrating electrodes 12 which are arranged so as to face the fixed electrode 11 and at least the central part thereof is movable in the thickness direction with respect to the fixed electrode 11. A connecting member 14 that connects the two electrodes, and has a plate-like shape, and is arranged so as to sandwich the vibration electrode 12 together with the fixed electrode 11 by facing the vibration electrode 12 from the opposite side of the fixed electrode 11. Two outer fixed electrodes 15 and 16. [Selection] Figure 1 |
