Abstract

Disclosed in the invention is a vibration motor comprising a housing formed by an upper shell 1 and a lower shell 2. A coil 3, spring plates, magnets, and a mass block are accommodated into a cavity encircled by the housing. The mass block 6 contains accommodation grooves 61 with the shapes matching the external profiles of the magnets 5; and the magnets 5 are accommodated into the accommodation grooves 61 and are used for providing magnetic fields for the vibration motor. The coil 3 that is fixed on the upper shell 1 and is connected with an external power supply is used for making induction with the magnets 5 during electrification to generate a driving force. The spring plates 4 are respectively arranged at diagonal positions of the lower shell 2. The mass block 6 that is connected to the lower shell 2 by the spring plates and is suspended inside the housing makes vibration horizontally along the diagonal direction of the housing under the effect of the driving force. According to the invention, the diagonal vibration of the motor can be realized and thus a multi-azimuth vibration effect with vibration at the X direction and the Y direction can be realized, so that the good user experience can be provided. Moreover, on the basis of the principle that the diagonal line is the longest, displacement needed by vibration can be met and thus space is saved.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a vibration motor and electronic equipment. Background technique [0002] Currently, the vibrators or motors of existing electronic products on the market generally vibrate in the Z direction or the X direction, and the vibration feedback is relatively simple, which makes it impossible for consumers to achieve a multi-range tactile and vibration feedback experience. [0003] The pure X-direction or other vibration requires a lot of product space, which is an obstacle to the increasingly miniaturized development of products. [0004] In view of the fact that products are becoming more and more sophisticated, miniaturized, fast-paced, high-quality, and low-cost, and the body is getting thinner and thinner, a new vibration motor is urgently needed to meet market demand. Contents of the invention [0005] The invention provides a vibrating motor and electronic equipment to solve the problem...
