Patent number: 9357311Abstract: The present disclosure provides a speaker. The speaker includes a frame, a magnetic circuit system disposed within the frame, and a vibrating system disposed above the magnetic circuit system and connected with the frame. The vibrating system includes a diaphragm that includes a vibrating portion having a far portion away from the magnetic circuit system and an adjacent portion adjacent to the magnetic circuit system. An avoid part for avoiding the adjacent portion is disposed at a position on the magnetic circuit system that corresponds to the adjacent portion of the diaphragm which ensures the maximum amplitude of the diaphragm to avoid noises that would be generated due to collision with the magnetic circuit system when the vibrating system operates at the maximum amplitude.Type: GrantFiled: December 3, 2014Date of Patent: May 31, 2016Assignees: AAC Microtech (Changzhou) Co., Ltd., AAC Acoustic Technologies (Shenzhen) Co., Ltd.Inventors: Yunxia Xu, Bin Cai
