The present disclosure provides a linear vibration motor, including a casing with an accommodation space, a vibration unit accommodated in the accommodation space, a vibration unit suspended in the accommodation space and a coil fixed on the casing and driving the vibration unit to vibrate. The casing includes a copper ring arranged around the vibration unit. In the linear vibration motor provided by the utility model, the copper ring is arranged around the vibration unit to provide a damping function for the linear vibration motor. Compared with the foam damping member in the related art, the linear vibration motor provided by the present disclosure may be arranged by an automatic device during the production and manufacture of the linear vibration motor, thereby greatly improving the production efficiency, and improving the automation degree.

Linear vibration motor with casing having copper ring and vibration unit with magnetic steel assembly

The present disclosure provides a vibration motor, including a housing with an accommodation space; a vibration part and a stator contained in the accommodation space; an elastic support suspending and supporting the vibration part in the accommodation space for providing elastic restoring force to the vibration part. The elastic support includes a first fixed part fixed on the vibration part, an elastic arm with one end thereof connected to the first fixed part, and a second fixed part formed by bending another end of the elastic arm and fixed on the housing. An extension direction of the first fixed part is perpendicular to a vibration direction of the vibration part, and an extension direction of the second fixed part is parallel to the vibration direction. Thus, the service life of the elastic support is improved.

Vibration motor with elastic support having acute bending angle and obtuse angle

One of the objects of the present invention is to provide a linear vibration motor which enhances vibration performance. To achieve the above-mentioned object, the present invention provides a linear vibration motor having a housing body with an accommodation space; a vibration unit accommodated in the accommodation space; an elastic member suspending the vibration unit in the accommodation space; and a coil assembly fixed to the housing body for driving the vibration unit to vibrate. The vibration unit includes a magnet assembly having a plurality of first magnets arranged along a vibration direction of the vibration unit, and at least one second magnet sandwiched between two adjacent first magnets, for forming a magnetic circuit.
