Patent number: 10694294Abstract: An electro-acoustic product, and more particularly to a metal diaphragm and a speaker. The metal diaphragm includes a hemispherical diaphragm portion that is provided with a central convex, a hemispherical diaphragm portion periphery is extended in a horizontal direction and configured to form an annular flat diaphragm portion, a annular flat diaphragm portion periphery is folded toward the convex direction of the hemispherical diaphragm portion and configured to extend away from the hemispherical diaphragm portion to form a trumpet-shaped diaphragm portion; a height of a trumpet-shaped diaphragm outer periphery portion away from the hemispherical diaphragm portion is greater than a height of a top portion of the hemispherical diaphragm portion. Thereby the split distortion of the speaker at high-frequency is reduced to ensure that the metal diaphragm can be normally vibrated to produce sound.Type: GrantFiled: January 14, 2019Date of Patent: June 23, 2020Assignee: SHENZHEN GRANDSUN ELECTRONIC CO., LTD.Inventors: Gang Xie, Haiquan Wu, Weiyong Gong, Mickael Bernard Andre Lefebvre, Ruiwen Shi

Patent number: 10667058Abstract: A diaphragm, including: a metal dome, a non-metallic diaphragm portion, and a flexible rim. The non-metallic diaphragm portion is bonded to a metal dome outer periphery, and a non-metallic diaphragm portion outer periphery extends corresponding to a convex direction of the metal dome and expands radially away from the metal dome. The flexible rim is bonded to the non-metallic diaphragm portion outer periphery. The diaphragm of the present application adopts the combination of the metal dome, the non-metallic diaphragm portion, and the flexible rim, the overall rigidity of the diaphragm is enhanced, and the internal damping property of the diaphragm and the compliance of the vibration of the diaphragm can be adjusted, which can effectively reduce segmentation vibration of the diaphragm during high-frequency vibration and reduce the segmentation distortion of the diaphragm at high frequencies, thereby extending the bandwidth of the diaphragm.Type: GrantFiled: January 14, 2019Date of Patent: May 26, 2020Assignee: SHENZHEN GRANDSUN ELECTRONIC CO., LTD.Inventors: Gang Xie, Haiquan Wu, Weiyong Gong, Mickael Bernard Andre Lefebvre, Ruiwen Shi
