Problems solved by technology

[0003] 1. The thickness of the circular vibration motor is relatively large, so it is difficult to realize the light and thin design of electronic products
[0004] 2. The circular vibration motor installed in the electronic product has a poor fit with other components. During the production and transportation of electronic products, the circular vibration motor is easy to roll off
[0005] In view of the defects of circular vibration motors, some existing manufacturers use square vibration motors instead of circular vibration motors. However, the springs in square vibration motors are conventional spring structures. Interference and noise, and the number of spring arms is small, the internal stress of the spring is too large, the vibration fatigue life is short, and the phenomenon of fracture is easy to occur, resulting in a short service life of the motor

[0039] see figure 1 , the dotted line on the sub-arm 121 in the figure represents the dividing line between each part, the shape of each part is not required to be completely consistent with the figure, and the shape of each part in the figure is only for illustration. The straight dotted line between the two sub-arms 121 in the figure represents the symmetry line of the arm assembly 120 .

[0040] This embodiment provides a spring 100, which is a cone spring. The spring 100 is mainly used in the polygonal vertical linear vibration motor 200 . The spring 100 includes an inner ring 110 and a plurality of moment arm assemblies 120 connected to the outer periphery of the inner ring 110 . In this embodiment, the number of arm assemblies 120 is four. Four moment arm assemblies 120 are evenly connected to the outer circumference of the inner ring 110 .

[0041] The arm assembly 120 includes two sub-arms 121 arranged symmetrically to each other. One end of the two sub-arms 121 is...

Abstract

The present invention provides a spring and a polygonal vertical linear vibration motor, and relates to the technical field of vertical linear vibration motors. The spring is applied in a polygonal vertical linear vibration motor. The spring comprises an inner ring and a plurality of force arm modules connected with the periphery of the inner ring; each force arm module comprises two sub force arms which are mutually symmetrical, one ends of the two sub force arms are connected with the periphery of the inner ring, and the other ends of the two sub force arms are connected. There are many force arms of the spring, the vibration process is small in noise, small in internal stress and long in vibration fatigue life.

Description

technical field [0001] The invention relates to the technical field of vertical linear vibration motors, in particular to a spring and a polygonal vertical linear vibration motor. Background technique [0002] At present, the vertical linear vibration motors used in electronic products such as mobile phones are mostly circular. However, the use of circular vibration motors in electronic products has at least the following defects: [0003] 1. The thickness of the circular vibration motor is relatively large, so it is difficult to realize the light and thin design of electronic products. [0004] 2. The circular vibrating motor installed in the electronic product has a poor fit with other components, and the circular vibrating motor is easy to roll off during the production and transportation of the electronic product. [0005] In view of the defects of circular vibration motors, some existing manufacturers use square vibration motors instead of circular vibration motors. H...
