Linear vibration motor and vibration device

Abstract

The invention discloses a linear vibration motor and a vibration device, and relates to the field of linear vibration motors. The linear vibration motor comprises a housing, an FPC board, a coil assembly, a vibration structure and an elastic member. The FPC board is disposed inside the housing, and the coil assembly, the vibration structure and the elastic member are all disposed inside the housing. The two ends of the elastic member are respectively connected to the vibration structure and the housing, and the coil assembly is connected to the FPC board. The vibration structure comprises a first magnet, a second magnet and a vibration body, wherein the second magnet is connected to one side of the first magnet. The coil assembly stretches into the first magnet from one side, far from thesecond magnet, of the first magnet and is spaced apart from the first magnet, and the vibration body is connected to the outside of the first magnet. The vibration device employs the linear vibrationmotor described above. The linear vibration motor and the vibration device provided by the invention can increase the vibration amount and ensure that a user obtains the information in time.

Description

technical field [0001] The invention relates to the field of linear vibration motors, in particular, to linear vibration motors and vibration equipment. Background technique [0002] In the rapidly developing information age, the transmission of information has become a very important technology in today's society. In the way of information transmission, the way of transmitting information through mechanical vibration is also a commonly used technology. For example, a mobile terminal such as a mobile phone is equipped with a vibration motor, so that the vibration of the vibration motor transmits information to the user, that is, the user of the mobile phone knows that there is information transmitted to the mobile phone through vibration, so that the user can obtain information in time. [0003] In the prior art, most current vibration equipment such as mobile phones use linear vibration motors as the vibration source of mechanical vibration, but the amount of mechanical vi...

Problems solved by technology

[0003] In the prior art, most current vibration equipment such as mobile phones use linear vibration motors as the vibration source of mechanical vibration, but the amount of mechanical vibration that most current linear vibration motors can generate is not enough, and often occurs The vibration motor generates vibration, and the user cannot receive the vibration information, which greatly causes delays in information and brings great inconvenience to the user.
