Problems solved by technology

The above-mentioned linear motors have a single vibration direction, and there is only one main operating frequency point available for driving, and one application bandwidth
With the popularization of hand-held AR&VR feedback devices and game consoles, unidirectional and single-frequency linear motors are far from enough. Linear motors with multiple vibration directions and multiple main frequency drives have become technical problems that must be overcome.

Embodiment 1

[0037] see Figure 1-10 , the present invention provides the following technical solutions: a moving coil type multi-directional vibrating linear motor, comprising a support frame 6, an upper cover 1 is connected above the support frame 6, side cover plates 8 are connected to both sides of the support frame 6, The inside of the support frame 6 is provided with a vibrator assembly, the vibrator assembly and the support frame 6 are connected by elastic pieces 10, the two sides of the support frame 6 are connected with a stator assembly, and the vibrator assembly includes a soft board 2, a coil 3 and an iron core 5, wherein the iron The two sides of the core 5 are respectively connected to the support frame 6 through the shrapnel 10, the coil 3 is connected to the two ends of the iron core 5, the soft board 2 is connected to the top of the iron core 5, the soft board 2 is connected to the upper cover plate 1, and the coil 3 It is electrically connected with the soft board 2 , and...

Embodiment 2

[0050] This embodiment differs from Embodiment 1 in that further, the two outer flat ends of the elastic piece 10 are fixedly connected to the iron core 5 and the support frame 6 respectively, and the two inner flat ends of the elastic piece 10 are respectively connected to a pressure plate 11 .

[0051] By adopting the above-mentioned technical scheme, the shrapnel 10 is a material with relatively large elastic deformation capacity. In this embodiment, stainless steel material is selected, and its special shape design ensures that it can realize linear motion in two directions ( image 3 The direction shown by the middle arrow), and ensure that the modes corresponding to these two motions are in the first two orders, so as to avoid the modes except these two linear motion modes from being excited by the driving signal, and the pressure plate 11 fixes the points formed by the welding process into The surface is fixed, so that the damage caused by the welding process is located ...

Abstract

The invention discloses a moving coil type multi-directional vibrating linear motor, which comprises a support frame, an upper cover plate is connected above the support frame, side cover plates are connected to both sides of the support frame, and a vibrator assembly is arranged inside the support frame. The vibrator assembly and the support frame are connected by shrapnel, the two sides inside the support frame are connected with the stator assembly, the two sides of the iron core are respectively connected to the support frame by shrapnel, the two ends of the iron core are connected with coils, and the upper part of the iron core is connected with a soft The soft board is connected to the upper cover, and the magnetic steel group is connected to the side cover; the invention also discloses a method for realizing a dynamic multi-directional vibrating linear motor. The iron core of the present invention makes the coil have a larger inductance, which ensures a larger magnetic flux and a larger driving force when the coil is energized; Release a certain deformable area to ensure that the soft board has enough area to participate in the deformation when the iron core moves.

Description

technical field [0001] The invention belongs to the technical field of linear motors, and in particular relates to a moving-coil multi-directional vibration linear motor and a realization method thereof. Background technique [0002] Along with the popularization of front-end large groups and large users in the fields of mobile phone applications and smart wearables, motor technology has developed in the long run and is becoming increasingly mature. As emerging fields such as immersive game consoles, AR, and VR continue to mature, the requirements for haptics become more varied and complex. [0003] With the increasing experience needs of users, the structure of motors, as the source of tactile sensation of electronic products, has also undergone earth-shaking changes. From cylindrical motors, to flat motors, to linear motors, the tactile sensations provided are becoming more and more diverse and refined. At present, in high-end equipment, in order to pursue the experience...
