Abstract: A speaker system and electronic device are provided. The speaker system includes a first housing, a first accommodating cavity is arranged inside the first housing; a first active vibrating diaphragm, the first active vibrating diaphragm is arranged inside the first accommodating cavity; a second housing, a second accommodating cavity is arranged inside the second housing, and the second accommodating cavity is communicated with the first accommodating cavity to form a closed cavity; a first passive vibrating diaphragm, the first passive vibrating diaphragm is arranged on one side of the second housing and is driven by the first active vibrating diaphragm to vibrate. The present disclosure can reduce the displacement distance of the first passive vibrating diaphragm, weaken a low-frequency vibration sensation of the speaker system, and improve low-frequency performance of the speaker system.

Abstract: Disclosed is a loudspeaker, including: a vibration system; a magnetic circuit system comprising a magnetic basket, a central magnet fixed to the magnetic basket, and a peripheral magnet fixed to the magnetic basket and disposed surrounding the central magnet. Compared with conventional technologies, the obliquely magnetized peripheral magnet can extend the lengths of effective magnetic field lines, equivalent to increasing the thickness of the peripheral magnet; meanwhile, fitting between the central special-shaped magnet and the peripheral special-shaped magnet achieves non-linear BL control; the loudspeaker described herein increases the total magnetic energy product via the special-shaped magnets, which increases the loudspeaker BL and alleviates BL non-linearity.

Abstract: A loudspeaker system and an electronic device are provided according to the present disclosure. The loudspeaker system includes a first housing, where a first accommodating cavity is defined in the first housing, at least one passive diaphragm, arranged in the first accommodating cavity, a second housing, where a second accommodating cavity is defined in the second housing, an active diaphragm is provided in the second accommodating cavity, the second accommodating cavity is divided into a second front cavity and a second rear cavity by the active diaphragm, and the second rear cavity is in communication with the first rear cavity to form a closed cavity, a central magnetic block fixed on a side of the passive diaphragm away from the first front cavity and a magnetic assembly, including a first magnetic member arranged in the first front cavity and a second magnetic member arranged in the first rear cavity.
