The invention provides a linear vibration motor. The linear vibration motor comprises a shell, a cover body, a magnetic path system and a vibrator system, wherein the cover body is matched with the shell to form an accommodating space, the magnetic path system is accommodated in the accommodating space, the vibrator system is driven by the magnetic path system and comprises an elastic part, a coil and a balancing weight, the coil and the balancing weight are arranged in the accommodating space by the elastic part in a suspension way and vibrate in a direction perpendicular to the cover body, the cover body comprises a body and bulges, and the bulges are formed by protruding towards the inside of the accommodating space from the body and are fixedly connected with the elastic part. Compared with the prior art, the linear vibration motor provided by the invention has the advantages that the bulges and the elastic part are fixedly connected, so that the steps of positioning and connecting a fixed block and a cover plate in the assembly process are omitted, and a possible risk of reliability between the cover plate and the fixed block is also prevented.
Description
【Technical field】 [0001] The invention relates to a vibration motor, in particular to a linear vibration motor with an optimized magnetic circuit. 【Background technique】 [0002] With the development of electronic technology, portable consumer electronic products are becoming more and more popular, such as mobile phones, handheld game consoles, navigation devices or handheld multimedia entertainment equipment, etc. These electronic products generally use vibration motors for system feedback. Such as mobile phone call prompts, information prompts, navigation prompts, vibration feedback of game consoles, etc. Such a wide range of applications requires high performance vibration motors. [0003] A linear vibration motor in the related art includes a cover, a fixed block connected to the cover, and the vibrator system, and the vibrator system includes an elastic component fixedly connected to the fixed block. When assembling, the cover body and the fixing block need to be posi...
