Patent number: 8410642Abstract: A linear vibrator is disclosed. The linear vibrator includes a housing having a base and a cover, a number of elastic members connected to the housing, a vibrating unit suspended in the housing by the elastic members, and a coil positioned in the housing. The base has a bottom wall and a plurality of sidewalls extending vertically from the bottom wall. The vibrating unit has a magnet assembly and vibrates along a direction parallel to the bottom wall. The base further has a block located on the bottom wall. The block is located on a vibration path of the weight contacting the weight during vibration. An effective elastic displacement of the elastic member is not smaller than a distance between the block and a part contacting the block of the weight.Type: GrantFiled: May 6, 2010Date of Patent: April 2, 2013Assignees: AAC Acoustic Technologies (Shenzhen) Co., Ltd., American Audio Components Inc.Inventors: Le-Ping Dong, Hong-Fu Xu

Patent number: 8400027Abstract: A flat linear vibrating motor includes a cover, a base forming a receiving cavity together with the cover, a coil fixed on the base, an elastic member coupled to the base, a vibrator suspended in the cavity by the elastic member. The elastic member includes a mounting section coupled to the base, an arm extending from the mounting section, a free end extending from the arm, and a binder. The binder includes two plates for clamping the vibrator and a coupling section coupling the two plates for positioning the free end between the vibrator and the coupling section.Type: GrantFiled: January 30, 2010Date of Patent: March 19, 2013Assignees: AAC Acoustic Technologies (Shenzhen) Co. Ltd., American Audio Components Inc.Inventors: Le-Ping Dong, Hong-Fu Xu

Patent number: 8395286Abstract: The linear vibrator includes a base forming a hollow space, a suspension fixed on the base, and an oscillating portion suspended in the hollow space by the suspension. The suspension defines a flat part, a connecting portion bent downward from the flat part, and a spring portion extended horizontally in a direction parallel to flat part from the end of the connecting portion. The suspension is directly connected with the outside component, thereby transmitting the vibration to the outside component rapidly.Type: GrantFiled: August 17, 2010Date of Patent: March 12, 2013Assignees: AAC Acoustic Technologies (Shenzhen) Co., Ltd., American Audio Components Inc.Inventors: Hong-Fu Xu, Le-Ping Dong, Wei Zhang
