Embodiment Construction

[0031] 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.

[0032] In order to solve the problems of low vibration and poor user experience in existing motors, a magnetic reinforcement is provided between the permanent magnets of the vibrator, and the magnetic field strength generated by the permanent magnet is increased through the magnetic reinforcement, so that the magnetic field lines passing through the stator are increased. Improve the vibration effect of the product.

[0033] In order to describe the linear vibration motor of the present invention in detail, specific embodiments of the present invention will b...

Abstract

The invention provides a linear vibration motor, which comprises a vibration and a stator parallelly set to the vibrator, wherein the vibrator comprises a counter weight block and a vibration block inserted in the counter weight block; the stator comprises a stator coil and a magnet conductive core set inside the stator coil; the vibration block comprises at least two adjacently set permanent magnets and a magnetic force reinforced member set between the two adjacently set permanent magnets; the magnetic force reinforced members are permanent magnets; the polarities of adjacent ends ofthe two adjacently set permanent magnets are identical; and the magnetizing direction of the magnetic force reinforced member is vertical to that of the adjacently set permanent magnets. By utilizing the vibration motor, the magnetic field strength of the permanent magnets can be strengthened; and the magnetic force line of the stator coil penetrating through the stator is increased, thereby improving the vibration sense of the product.

Description

technical field [0001] The invention relates to the technical field of consumer electronic products, and more specifically, relates to a linear vibration motor applied to portable consumer electronic 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 counterw...
