AI Technical Summary
Technical Problem
The high positional accuracy requirements for welding in existing vibration motors, due to flush edges of the welding sheet and fixing part, lead to abutment issues affecting product performance and yield.
Method used
A vibration motor design where the welding sheet on the fixing part is spaced apart from the vibrator, with a damping member and slot configuration to ensure smooth operation and reduced positional accuracy needs, enhancing the contact between the spring support and vibrator.
Benefits of technology
This design reduces interference between the welding sheet and vibrator, improving the performance and yield of the vibration motor by minimizing positional accuracy requirements and ensuring stable operation.

Abstract
The vibration motor of the present invention includes a spring support, a vibrator connected to the spring support, and a housing that accommodates the spring support and the vibrator. The spring support includes a fixed portion connected to the vibrator, an elastic arm extending from the fixed portion, and a joint extending from the elastic arm and connected to the housing. The fixed portion includes a first surface connected to the vibrator, a second surface opposite the first surface, and a first side surface connecting the first and second surfaces and abutting the vibrator. A first welding sheet is provided on the second surface, and the first welding sheet has a second side surface corresponding to the first side surface, with a gap between the second side and the vibrator. In the vibration motor, the first welding sheet does not interfere with the abutment between the fixed portion and the vibrator, reducing the positional accuracy requirements when welding the spring support and the first welding sheet and ensuring abutment between the spring support and the vibrator. This eliminates the impact of the welding sheet on product performance and yield, thereby improving the performance and yield of the vibration motor.
