Embodiment Construction

[0027] In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more embodiments. It may be evident, however, that these embodiments may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate describing one or more embodiments.

[0028] The "mass block" used in the description of the following specific embodiments may also be referred to as a "counterweight block", which refers to a high-quality, high-density metal block that is fixed to the vibrating block that generates vibration to enhance vibration balance. In addition, the invention is mainly used for the improvement of miniature vibration motors, but it does not exclude the application of the technology in the invention to large vibration motors. However, for the convenience of expression, in the description of the following em...

Abstract

The invention provides a linear vibration motor. The linear vibration motor comprises a shell, a vibrator and a stator fixed on the shell and arranged to be parallel to the vibrator; the vibrator comprises a mass block and a permanent magnet, and the two ends of the mass block are arranged in the shell in a hanging mode through corresponding elastic supports respectively; each elastic support comprises an opening end, a connecting end and an elastic arm located between the opening end and the connecting end, and each elastic arm is provided with at least one elastic bending part; the opening ends are fixed on the opposite two side walls of the mass block, the corresponding connecting ends are fixed on the side walls, opposite to the ends of the mass block, of the shell. By means of the linear vibration motor, strong resilience can be provided for vibration of the vibrator, and shaking or deflection of the vibrator is avoided.

Description

technical field [0001] The invention relates to the technical field of consumer electronics, and more specifically, relates to a linear vibration motor applied to portable consumer electronics products. 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. However, with the development trend of thinner and lighter electronic products, various internal components also need to adapt to this trend, and the micro vibration motor is no exception. [0003] Existing miniature vibrating motors generally include an upper cover, a lower cover forming a vibration space with the upper cover, a vibrator (including counterweights ...
