Background technique

With the application and popularization of screen sound technology on high-end mobile phones, the application of electromagnetic vibrators (Electro-Magnetic Actuator, EMA) has become more and more widespread. There are two main types of EMA devices: resonant EMA devices and direct drive EMA devices. Resonant EMA devices can be used as non-porous earpieces and linear motors, and can be applied to flexible organic light emitting display (OLED) screens, hard OLED screens or liquid crystal display (LCD) screens, but the disadvantage is sound The transmission does not have obvious directionality and the leakage is large. Direct-drive EMA devices can be used as non-porous earpieces and linear motors, and can be applied to flexible OLED screens or back cover speakers. The advantages are small sound leakage, large loudness, and hearing feeling close to ordinary earpieces. According to the current development trend, direct-drive EMA devices are the main direction for the future development of this technical field, but there is also a fatal problem: high loudness and low privacy. If the loudness is reduced, it will cause the user to use the whole process. Insufficient loudness.
