Patent number: 8938086Abstract: A micro-speaker includes a case having a cavity and a receiving hole, a magnetic circuit unit and a vibrating unit with a voice coil received in the cavity, a pair of needle seats embedded in the case for electrically connecting with the voice coil, a pair of pogo-pins arranged in the receiving hole for electrically connecting with the pair of needle seats. Each of the pogo-pins has a barrel unit, a first protrusion and a second protrusion extending from an outer surface of the barrel unit, at least one plunger extending from the barrel unit and projecting out of the receiving hole, a receiving space formed between the first protrusion and the second protrusion. A third protrusion extends from an inner surface of the receiving hole and accommodated in the receiving space for fixing the pogo-pin in the corresponding receiving hole.Type: GrantFiled: January 23, 2013Date of Patent: January 20, 2015Assignees: AAC Acoustic Technologies (Shenzhen) Co., Ltd., AAC Microtech (Changzhou) Co., Ltd.Inventors: Xiong Zhang, San-You Wu

Patent number: 8649550Abstract: Disclosed is a multi-magnet system for speaker. The multi-magnet system includes a yoke having a bottom, a pair of main magnets separated from each other and mounted on the bottom of the yoke, respectively, a mid-magnet mounted on the bottom of the yoke and located between the pair of main magnets, and a pair of auxiliary magnets attached to two ends of the yoke. Wherein, the first main magnet together with the first auxiliary magnet and the mid-magnet defines a first magnetic gap and the second main magnet together with the second auxiliary magnet and the mid-magnet defines a second magnetic gap. By virtue of place the magnets at appropriate locations, the sensitivity of the speaker is effectively enhanced.Type: GrantFiled: December 20, 2011Date of Patent: February 11, 2014Assignees: AAC Acoustic Technologies (Shenzhen) Co., Ltd., American Audio Components Inc.Inventors: Lei Shi, Wen-tao Jiang, Xiong Zhang, San-you Wu, Lin-zhen Li

Patent number: 8630441Abstract: A multi-magnet speaker is disclosed. The multi-magnet speaker includes a frame defining a hollow space, a magnetic system defining a yoke and a plurality of magnetic gaps positioned in the hollow space, a diaphragm mounted on the frame and a plurality of coils attached to the bottom of the diaphragm. The diaphragm includes a plurality of vibrating membranes each defining a dome part and an arcuate portion radially extending from the periphery of the dome part. Each of the coils is received in the corresponding magnetic gap to drive the corresponding vibrating membrane to vibrate.Type: GrantFiled: December 14, 2011Date of Patent: January 14, 2014Assignees: AAC Acoustic Technologies (Shenzhen) Co., Ltd., American Audio Components Inc.Inventors: Lei Shi, Wen-Tao Jiang, Xiong Zhang, San-You Wu, Lin-Zhen Li
