Abstract: A long stroke speaker is provided in the present disclosure. The long stroke speaker includes a shell, a magnetic system, and a vibrating system. The magnetic system includes a magnet assembly and a magnetic guiding module cooperatively for forming a magnetic gap. The vibrating system includes a membrane, a coil support connected to the membrane, and a voice coil connected to the coil support. The magnet assembly includes a first magnet, a second magnet and a pole member, a magnetic direction of the first magnet and a magnetic direction of the second magnet are parallel to a vibration direction of the vibrating system, and an end of the first magnet adjacent to the pole member has a same polarity as an end of the second magnet adjacent to the pole member. The voice coil is arranged at the magnetic gap and surrounds the pole member.
