摘要： Embodiments of this application disclose an electroacoustic transducer, including a center magnet, two first side magnets, two second side magnets, a voice coil, a voice diaphragm, and two flexible printed circuit boards. The two first side magnets are symmetrically arranged on two sides of the center magnet, and a first gap is formed between the first side magnet and the center magnet. One end of the voice coil is partially located in the first gap, and the voice diaphragm is fixedly connected to the other end of the voice coil. The two flexible printed circuit boards are symmetrically arranged on two sides of the center magnet. The electroacoustic transducer has comparatively high magnetic induction strength and comparatively high sensitivity.
