Abstract: The present application provides a vibration exciter, which includes a casing with an accommodating space, a vibration unit suspended in the accommodating space, an elastic unit connected to the vibration unit and arranged in the accommodating space, and a drive unit fixed to the casing and configured to drive the vibration unit to vibrate. The vibration unit includes a mass block in a ring shape, a rubber coating member wrapped outside the mass block and internally form an installation cavity, a pole core combined with the rubber coating member and arranged inside the installation cavity, and a magnetic steel fixed on a side of the pole core away from the mass block. The drive unit is accommodated in the installation cavity. The vibration exciter of the present application can effectively reduce production costs and improve the fixation stability between the mass block, the magnetic steel and other components.

Abstract: A linear vibration motor, including a housing, a weight suspended in the housing, at least two driving assemblies driving the weight to horizontally vibrate, and an elastic connector elastically supporting the weight. The weight includes an inner wall enclosing to form a through hole, each driving assembly includes a solenoid fixed to the housing and a magnet assembly fixed to the inner wall, the magnet assembly includes first magnets arranged at two sides of the solenoid along a vibrating direction of the weight, the first magnets are magnetized along a direction perpendicular to the vibrating direction, the first magnets at two sides of the solenoid have poles of a same polarity opposite to each other, each first magnet includes a common magnet located between two adjacent solenoids and shared by two adjacent driving assemblies. A driving force of the linear vibration motor is significantly improved.

Abstract: The present application provides a vibration motor, including a casing with an accommodating space, a vibrator assembly, a stator assembly, and elastic members accommodated in the accommodating space. The stator assembly is fixed to the casing, and the vibrator assembly is movably connected to the casing through elastic members. The vibrator assembly includes a support assembly having two ends fixedly connected to corresponding elastic members, and the stator assembly is fixed to the casing. The support assembly includes a skeleton and an adhesive layer at least partially covered on an outer side of the skeleton. The vibrator assembly further includes a coil nested outside the adhesive layer, and the stator assembly is configured to provide a driving force for the vibrator assembly to move along a vibration direction.
