Problems solved by technology

In related technologies, the resonant frequency of the vibration block in the linear motor is the natural frequency, which is determined by the elastic coefficient and mass of the vibration system, and the spring coefficient and mass are determined after the product is completed and cannot be changed, so the resonant frequency of the linear motor is single And not adjustable, unable to meet its requirements in different application scenarios

Description

【Technical field】 [0001] The invention relates to the technical field of linear motor drive, in particular to a linear motor system. 【Background technique】 [0002] With the development of electronic technology, portable consumer electronic products, such as mobile phones, handheld game consoles, navigation devices or handheld multimedia entertainment devices, are becoming more and more popular. Vibration feedback, as a form of feedback in portable electronic products, has gradually expanded its application scope from providing only the most basic incoming call reminders to providing tactile feedback associated with applications and scenes. The motor is the basic component that provides vibration feedback in mobile devices, and usually includes rotary motors, piezoelectric motors, and linear motors. Among them, linear motors have absolute advantages in providing tactile feedback functions related to applications and scenes due to their small size, long life, low power consu...
