Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] Such as figure 1 , 2 As shown in and 3, it is a flat linear vibration motor 1 provided by the present invention, which includes an elongated housing 10 with an accommodating space 100 inside, a housing 10 housed in the housing 10 and fixed to the housing 10. The first magnetic steel 11, the vibration unit 12 suspended in the housing 10, and the second magnetic steel 13 fixed to the housing 10, wherein the first magnetic steel 11, the vibration unit 12 and the second magnetic steel 13 are arranged in sequence along the vibration direction X-X of the vibration unit 12 . The vibration motor 1 includes driving coils 16 spaced above the vibration unit 12 for driving the vibration unit 12 to reciprocate and vibrate along the vibration direction X-X of the vibration unit 12 . The vibration motor 12 also includes a motor that is arranged between the vibration unit ...

Abstract

The invention discloses a flat linear vibration motor. The flat linear vibration motor comprises a shell internally equipped with accommodating space, a vibration unit suspended in the shell, and a sliding pair arranged between the vibration unit and the shell; the vibration motor further comprises a drive coil which is accommodated in the accommodating space, assembled above the vibration unit, and spaced with the vibration unit, and the driving coil drives the vibration unit to circularly vibrate along the vibration direction of the vibration unit after being electrified. The flat linear vibration motor is characterized in that restoring force is provided by repulsive force relatively generated by the same poles of the magnetic steel, and the vibration unit is positioned by the sliding pair, so that performance and service life of the motor cannot be affected when spring parts of a traditional motor are ineffective and fatigue, and the performance of the vibration motor is effectively increased.

Description

【Technical field】 [0001] The invention relates to a vibration motor, in particular to a flat linear vibration motor used in portable consumer electronic products. 【Background technique】 [0002] With the development of electronic technology, portable consumer electronic products are becoming more and more popular, such as mobile phones, handheld game consoles, navigation devices or handheld multimedia entertainment equipment, etc. These electronic products generally use vibration motors for system feedback. Such as mobile phone call prompts, information prompts, navigation prompts, vibration feedback of game consoles, etc. Such a wide range of applications requires high performance and long service life of the vibration motor. [0003] The vibrating motor in the related art includes a housing, a vibration unit accommodated in the housing and a spring member, the spring member is used to suspend the vibration unit in the housing, and the spring member is used to provide rest...
