Abstract

The invention discloses a novel linear motor, and the linear motor comprises an upper motor cover and a lower motor cover. The interior of the upper and lower motor covers is provided with a spring, arotor assembly, a coil and an FPC board. The rotor assembly comprises a balance block, a magnetic yoke and a magnet. The lower end of the magnet is provided with a first flange edge cooperating withthe spring, and the upper end of the spring is in stacked welding connection with the first flange edge. The lower motor cover is provided with a second trough for installing the FPC board. The upperend of the lower motor cover is provided with a second flange edge cooperating with the spring and the upper motor cover. The lower end of the spring is in stacked welding connection with the second flange edge. The spring, the magnetic yoke and the lower motor cover are made of the same material. The upper end of the FPC board is provided with a plurality of first avoiding grooves cooperating leads of the coil. The linear motor provided by the invention is high in safety and reliability, is good in stability, enlarges the vibration space of the motor, is good in vibration effect, prolongs theservice life of the motor, enlarges the application range of the motor, and can be conveniently used for a power source of the touch feedback of an intelligent device.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a novel linear motor. Background technique [0002] With the rapid development of electronic products, especially mobile terminal devices such as mobile phones and tablet computers, these electronic devices basically use vibration generators to prevent noise from electronic devices from disturbing others. The traditional vibration generating device uses a rotor motor based on eccentric rotation, which realizes mechanical vibration through the rotation of the eccentric vibrator. During the rotation of the eccentric vibrator, the commutator and brushes will generate mechanical friction and electric sparks, etc., which will affect The rotational speed of the eccentric vibrator further affects the vibration effect of the device. Therefore, current vibration generating devices mostly use linear motors with better performance. [0003] Linear motors, also known as linear motors, linear...
