Problems solved by technology

However, since this type of motor has two vibrator components, the volume of the motor is increased, which greatly increases the space occupied by the linear vibration motor, which is not conducive to the development of terminal miniaturization.

Embodiment Construction

[0027] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0028] Such as figure 1 As shown, a linear vibration motor includes a housing, a vibrator assembly and a stator assembly accommodated in the housing, and an elastic support 30 for supporting the vibrator assembly. For ease of understanding, the transverse vibration direction of the vibrator assembly in the horizontal plane is defined is the first direction, the longitudinal vibration direction is the second direction, and the vibration direction of the vibrator assembly perpendicular to the horizontal plane is the third di...

Abstract

The invention discloses a linear vibration motor. The linear vibration motor comprises a shell formed with an accommodating space, a vibrator assembly which is suspended in the accommodating space through an elastic supporting part, and a stator assembly arranged on the inner side wall of the shell; and the elastic supporting part is set into a spiral elastic element, and one end is combined and fixed on the inner side wall surface of the shell while the other end is fixedly connected with the vibrator assembly. The linear vibration motor disclosed in the invention can realize vibration of three directions by one vibrator assembly, so that one linear vibration motor can have three different vibration feelings, thereby expanding the application scenarios of the motor; and in addition, by only setting one weighing block to realize three vibration feelings, the size of the linear vibration motor can be reduced, and the terminal miniaturization requirement can be satisfied.

Description

technical field [0001] The invention relates to the technical field of motors. More specifically, it relates to a linear vibration motor. Background technique [0002] With the development of communication technology, portable electronic products, such as mobile phones, handheld game consoles or handheld multimedia entertainment devices, have entered people's lives. In these portable electronic products, micro-vibration motors are generally used for system feedback, such as mobile phone call notifications, game console vibration feedback, and so on. [0003] Most of the linear vibration motors currently used in portable consumer electronics products have only one vibration direction, which makes it difficult to achieve different vibration effects, and the tactile feedback effect is relatively single. In order to obtain different vibration effects, there is currently a linear vibration motor with two vibrator assemblies with different vibration directions, and two different...
