Broadband vibration motor with case, vibrator and coil, and at least one reset part arranged opposite the vibrator

A broadband vibration motor, comprising:

• a case, comprising an inner cavity;
• a vibrator, arranged in the inner cavity, wherein the outer peripheral surface of the vibrator is provided with lubricating regulating oil, and the vibrator is suspended in the inner cavity through the lubricating regulating oil, wherein kinematic viscosity of the lubricating regulating oil at −15° C. is 680~900 mm2/S, and kinematic viscosity of the lubricating regulating oil at 23° C. is 60~65.5 mm2/S, and kinematic viscosity of the lubricating regulating oil at 40° C. is 30~35 mm2/S;
• a coil, configured to drive the vibrator to vibrate, wherein the coil is arranged around an outside of the vibrator;
• and
• at least one reset part, wherein the at least one reset part is magnetic, and the at least one reset part is correspondingly provided at both ends of the vibrator in the vibrating direction, and the at least one reset part is arranged with the same pole opposite to the vibrator.
