Document Type and Number:
WIPO Patent Application WO/2017/206065
Kind Code:
A1
Abstract:
An improved structure of a planar diaphragm monomer, comprising: a thin membrane layer (10), a first coil (31), a second coil (32), a third coil (33) and a fourth coil (34). The first coil (31) is provided on a first side (111) on a first face (11) of the thin membrane layer (10). The second coil (32) is provided on a first side (121) on a second face (12) of the thin membrane layer (10), and is electrically connected to the first coil (31). The third coil (33) is provided on a second side (112) on the first face (11) of the thin membrane layer (10), and is electrically connected to the second coil (32). The fourth coil (34) is provided on a second side (122) on the second face (12) of the thin membrane layer (10), and is electrically connected to the third coil (33). The first coil (31) and the third coil (33) are configured to be the same in the current direction at the same distance from a central line (A), and the second coil (32) and the fourth coil (34) are configured to be the same in the current direction at the same distance from the central line (A).
