Embodiment Construction

[0054] In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more embodiments. It may be evident, however, that these embodiments may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate describing one or more implementations.

[0055] The "mass block" used in the description of the following specific embodiments may also be referred to as "counterweight block", which refers to one of the components that cooperate with magnets or coils in the motor casing to vibrate as a vibrator assembly. In addition, the present invention is mainly used to improve the linear vibration motor used in the description, which may also be called a Z-direction vibration motor or a longitudinal vibration motor. However, for the convenience of expression, in the description of the following embodiments...

Abstract

The invention discloses a stopper bracket for a vibration motor and a linear vibration motor with the bracket. The stopper bracket comprises at least one body part which comprises a first connecting member. The first connecting member comprises a joint part, a first welding part and a second welding part. The body part further comprises a second connecting member located below the first connectingmember. The second connecting member is fixedly connected with the side edge of the first connecting member through a connecting arm. Pre-break lines are arranged on the joint of the connecting arm and the first connecting member and the joint of the connecting arm and the second connecting member. According to the stopper bracket provided by the invention, an elastic support member in motor assembly is no longer directly welded with a mass block, which reduces the damage of the elastic support member; the welding area of the elastic support member and the mass block is effectively increased;the connection quality and connection strength of the elastic support member and the mass block are improved; and the stability of the vibration of a vibrator assembly is improved.

Description

technical field [0001] The invention relates to the technical field of electronic products. More specifically, it relates to a stopper bracket for a vibration motor and a linear vibration motor including the bracket. Background technique [0002] With the development of communication technology, portable electronic devices, such as mobile phones, tablet computers, smart wearable devices, multimedia entertainment devices, etc., have become a necessity in people's lives. In these electronic devices, a miniature linear vibration motor is usually used for system feedback, such as vibration feedback when clicking a touch screen. A linear vibration motor is a component that uses the principle of electromagnetic force to convert electrical energy into mechanical vibration. Conventional linear vibration motors are usually installed in mobile communication terminals, portable terminals, etc., and are usually installed on the edge of the device, and receive vibration Vibrates in a d...
