Abstract: The present application provides a vibration motor, including a spring holder, a vibrator connected to the spring holder, and a casing. The spring holder includes a fixing portion connected to the vibrator, an elastic arm extending from the fixing portion, and an engagement portion. The fixing portion is provided with a first surface connected to the vibrator, a second surface, and a first side surface. The second surface is provided with a first welding piece, and the first welding piece is provided with a second side surface arranged opposite to the first side surface, and the second side is spaced apart from the vibrator. In the above-mentioned structure, the first welding piece does not interfere with the abutting fit between the fixing portion and the vibrator, thereby improving the performance and yield of the vibration motor.

Abstract: The present application provides a linear motor, including a casing, a vibrator assembly, and elastic brackets. The elastic brackets are arranged on both sides of a vibration direction of the vibrator assembly, including a first fixing portion connected to the casing, a second fixing portion connected to the vibrator assembly, and a connecting portion. An outer surface of the second fixing portion is provided with a welding tab, and the welding tab includes two first side edges arranged relatively parallel to each other and extended along the vibration direction, a second side edge and an arcuate edge connecting the two first side edges. The arcuate edge is protruded in a direction away from the second side edges. The edges of the welding tabs in the linear motor have an arcuate structure, which can improve the stress distribution of the elastic brackets and improve the lifespan of the product.

Abstract: The present application provides a linear vibration motor, including a casing, a stator and a vibrator accommodated in the casing, and an elastic member for suspending the vibrator in the casing. The vibrator includes a mass block having a through-hole, and a magnetic circuit system. The magnetic circuit system includes a first magnetic steel arranged on one side of the stator and a second magnetic steel arranged on the other side of the stator. The first magnetic steel and the second magnetic steel are extended in parallel and arranged centrally symmetrically around a geometric center of the stator. The first magnetic steel includes a first magnetic steel portion, and the second magnetic steel includes a second magnetic steel portion. The asymmetric magnetic circuit structure can improve the nonlinear vibration when the stator is offset during the arrangement, which is helpful for improving the stability and yield of the test.

Abstract: A system for digital certificate direction is provided. The system includes an application server having one or more applications and a user computer. The system also includes a certificate optional server that is operable to communicate with the user computer regarding access to the one or more applications. The certificate optional server is operable, when the user computer communication is associated with a digital certificate, to direct the user computer to a digital certificate mandated computer to promote access to the one or more applications. When the user computer communication is not associated with the digital certificate, the certificate optional server is operable to direct the user computer to a certificate generator.
