Title:
EARPHONE AND TRANSDUCER THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/060006
Kind Code:
A1
Abstract:
The present application mainly relates to an earphone and a transducer thereof. The transducer comprises a first magnetizer, a coil, and a magnet assembly. The orthographic projection of the coil on a reference plane perpendicular to a first reference direction surrounds the periphery of the orthographic projection of at least part of the first magnetizer on the reference plane, the orthographic projection of the magnet assembly on the reference plane surrounds the periphery of the orthographic projection of the coil on the reference plane, one of the first magnetizer and the magnet assembly is connected to the coil, and the magnetic field generated after an excitation signal is input to the coil interacts with the magnetic field formed by the magnet assembly, so that the first magnetizer and the magnet assembly move relatively. Therefore, the coil is connected to one of the first magnetizer and the magnet assembly, so that a magnetic gap between the first magnetizer and the magnet assembly is reduced, and the sensitivity of the transducer is higher.
