Vibrating motor

Abstract

The invention relates to the technical field of a vibrating motor, and particularly relates to a vibrating motor. The vibrating motor comprises a shell, a mass block, a stator, a vibrator and a conductive spring, wherein the shell has an accommodating space; the mass block is suspended in the accommodating space by an elastic part; the stator is arranged in the accommodating space and is fixed on the shell; the vibrator is fixedly arranged on the mass block and can drive the mass block to vibrate in a reciprocating mode relative to the stator; one end of the conductive spring is fixed with the mass block and is electrically connected with a coil; the other end of the conductive spring is fixed with the shell and is electrically connected with a power supply; and in the reciprocating process of the mass block, the conductive spring is always in a non-stretching state. According to the vibrating motor provided by the invention, the conductive spring always in the non-stretching state cannot form a tensile force at a wiring point, so that the wiring point is difficult to fatigue, and a case that the wiring point is broken off in the vibrating process of the mass block can be effectively prevented; and the vibrating motor is more stable in electrical connection, has few faults and is low in repair rate.

Description

technical field [0001] The invention relates to the technical field of vibration motors, in particular to a vibration motor. Background technique [0002] Portable consumer electronic products such as mobile phones, tablet computers, and handheld game consoles are becoming more and more popular among consumers. The above-mentioned electronic products generally use vibration signals for information feedback, such as incoming call reminders for mobile phones, vibration feedback for handheld game consoles, etc. The vibration reminder function has become the most important application of vibration motors in the field of consumer electronics. [0003] Existing linear vibration motors generally use electrified coils as stators, and mass blocks suspended in the motor housing with magnets installed as vibrators. The casing affects the vibration direction of the magnet, causing the magnet to deflect towards the casing, or even sucked to the casing. The casing of this linear vibratio...
