Title:
BONE CONDUCTION LOUDSPEAKER
Document Type and Number:
WIPO Patent Application WO/2019/134162
Kind Code:
A1
Abstract:
Disclosed is a magnetic circuit component (102, 3100, 3200, 3300, 3400, 3500, 3600, 3700, 4100, 4200, 4300, 4400, 4500, 4600, 4700, 4800, 4900, 5100, 5200, 5300, 5400, 5500, 5600, 600, 700, 800, 900, 1000, 1100, 1200, 1300) of a bone conduction loudspeaker. The magnetic circuit component (102, 3100, 3200, 3300, 3400, 3500, 3600, 3700, 4100, 4200, 4300, 4400, 4500, 4600, 4700, 4800, 4900, 5100, 5200, 5300, 5400, 5500, 5600, 600, 700, 800, 900, 1000, 1100, 1200, 1300) produces a first magnetic field. The magnetic circuit component (102, 3100, 3200, 3300, 3400, 3500, 3600, 3700, 4100, 4200, 4300, 4400, 4500, 4600, 4700, 4800, 4900, 5100, 5200, 5300, 5400, 5500, 5600, 600, 700, 800, 900, 1000, 1100, 1200, 1300) comprises a first magnetic element (202, 302, 402, 502, 602, 702, 802, 902, 1002, 1102, 1202, 1302, 1402, 1502, 1602, 1702), and the first magnetic element (202, 302, 402, 502, 602, 702, 802, 902, 1002, 1102, 1202, 1302, 1402, 1502, 1602, 1702) produces a second magnetic field. The magnetic circuit further comprises a first magnetic guide element (204, 304, 504, 604, 704, 804, 904, 1004, 1104, 1204, 1304, 1404, 1504, 1604, 1710) and at least one second magnetic element (308, 408, 508, 608, 714, 814, 914, 1316, 1408, 1508, 1708). The at least one second magnetic element (308, 408, 508, 608, 714, 814, 914, 1316, 1408, 1508, 1708) encircles the first magnetic element (202, 302, 402, 502, 602, 702, 802, 902, 1002, 1102, 1202, 1302, 1402, 1502, 1602, 1702), and forms a magnetic gap with the first magnetic element (202, 302, 402, 502, 602, 702, 802, 902, 1002, 1102, 1202, 1302, 1402, 1502, 1602, 1702). The magnetic field intensity of the first magnetic field in the magnetic gap is greater than the magnetic field intensity of the second magnetic field in the magnetic gap.
