Problems solved by technology
[0003] Existing linear vibration motors generally include a housing, a stator assembly, and a vibrator assembly. Linear vibration is achieved through the reciprocating motion of the vibrator assembly. However, the existing linear vibration motors usually vibrate in one direction of the vibrator assembly, which cannot meet the requirements for multi-directional vibration. need

The moving magnet linear vibration motor provided by the invention includes: a housing with a receiving space; two elastic members, which are relatively connected to the side walls of the housing; and a mass block, which is respectively connected to the two elastic members through the peripheral wall. Suspended in the accommodation space of the shell; there are two magnets, which are fixedly connected to both ends of the mass block, and the magnets form an acute or obtuse angle with the center line of the two elastic parts; the coil has two, which are connected to the corresponding The magnets are fixed on the shell at intervals, and the coil forms an acute or obtuse angle with the center line connecting the two elastic parts. The present invention can decompose the Lorentz force experienced by the coil into the component force in the first direction along the center line connecting the two elastic members, and the component force in the second direction perpendicular to the center line connecting the two elastic members. The magnet Correspondingly, it is subjected to two forces that are equal in magnitude and opposite in direction to the two components of the Lorentz force experienced by the coil, so that the oscillator assembly including the magnet and the mass block can vibrate in two directions perpendicular to each other.
Description
Technical field [0001] The invention relates to the technical field of vibration motors, and in particular to a moving magnet linear vibration motor. Background technique [0002] In recent years, miniature horizontal linear vibration motors have begun to be used in wearable devices, mobile phones and other fields, and have received good feedback from clients. This kind of motor has the advantages of clear and strong vibration feeling, fast response to various signals, and tactile feedback of realistic scenes. As this good experience is widely recognized, not only mobile phones, but also wearable device companies using linear motors, as well as car touch screens, and portable handheld game consoles have also shown strong interest. [0003] Existing linear vibration motors generally include a shell, a stator assembly and a vibrator assembly. Linear vibration is achieved through the reciprocating motion of the vibrator assembly. However, existing linear vibration motors usual...
