- Point Drive Speaker
is the technique that Edison invented.
Point-drive Speaker is using the 3 fundamental theories of existing technique “Looped reproducing system”, “Theory of point connection” and natural phenomenon “Theory of opposite phase”.
- Looped reproducing system
is modelling the system of musical instrument generating the sound and is defined as follows:
Vibration reproducing system connects main vibrating parts such as driver unit, movable part and diaphragm plate in a loop line.
- This speaker generates
non-plane wave, therefore, sound phase of diaphragm plate at each place is not equal and both sound phase does not deny each other.
It is not necessary to install an unit into the box. This is the plate diaphragm speaker of open to back, and reproducing till 30 Hz.
