Problems solved by technology

Due to the limitation of size and performance, this kind of shrapnel is prone to rotation and deflection during work, resulting in problems such as rubbing
Further, with the trend of miniaturization and thinning of electronic products, in order to save space, it is necessary to design the mass block of the longitudinal vibration motor into a structure with a non-circular cross-section, but since the non-circular mass block is not easy to balance the The supporting force is more prone to problems such as polarization and tilt

Abstract

The invention discloses a vertical vibration motor. The vibration motor comprises a housing, wherein the interior of the housing is provided with an accommodation cavity; a vibration block assembly which is disposed in the accommodation cavity and comprises a mass block and a magnet fixed on the mass block; an elastic assembly which is disposed to enable the vibration block assembly to be suspended in the accommodation cavity and comprises two first elastic pieces. The two first elastic pieces are respectively disposed at the upper and lower sides of the vibration block assembly, and the first elastic pieces extend in the long axis direction of the vibration block assembly. One end of each first elastic piece is connected to one end of the vibration block assembly in a long axis direction, and the other end of each first elastic piece is connected with the accommodation cavity. The two first elastic pieces are in central symmetry relative to the vibration block assembly. The vibration motor also comprises a coil and an external circuit, wherein the coil is disposed on a side surface of the magnet and is electrically connected with the external circuit, and the external circuit is electrically connected with external equipment.

Description

technical field [0001] The invention belongs to the technical field of electronic products, in particular, the invention relates to a longitudinal vibration motor. Background technique [0002] With the gradual development of electronic product technology, vibration motors have become commonly used functional devices in electronic products such as mobile phones and tablet computers. Existing miniature vibrating motors usually include a vibration assembly and a stator assembly. The vibration assembly is composed of a mass block, a permanent magnet and a shrapnel, and the stator assembly is composed of an FPCB, a damper, a limit block and a coil. In order to enable the vibrating assembly to vibrate back and forth, the vibrating assembly further includes an elastic component, and the elastic component may generally be a structure such as a spring or a shrapnel. The structure of the spring is compact, but the radial stiffness is poor, and it needs to cooperate with the supporti...
