Patent number: 10932060Abstract: A screen component includes a screen body and at least one vibration assembly. The vibration assembly includes a movable member made from a giant magnetostrictive material and at least one coil surrounding the movable member, and the movable member is partially attached to the screen body. The at least one coil forms a magnetic field when the coil is supplied with an input current. The movable member deforms under the effect of the magnetic field. The magnetic field changes according to a change in parameter of the input current. A deformation amount of the movable member changes according to the change in magnetic field of the coil to drive the screen body to vibrate to output corresponding sound information by the screen component.Type: GrantFiled: November 25, 2019Date of Patent: February 23, 2021Assignee: BEIJING XIAOMI MOBILE SOFTWARE CO., LTD.Inventors: Na Du, Youhong Cheng, Lianwen Shan

Patent number: 10158937Abstract: A speaker module comprising a module housing is disclosed. A speaker unit is accommodated within the module housing. A sound hole of the module is located at a side of the speaker unit. The speaker unit divides a cavity of the entire module into two cavities, namely a front acoustic cavity and a rear acoustic cavity. The front acoustic cavity is in communication with the sound hole. A sound-absorbing cotton is provided in the front acoustic cavity. The sound-absorbing cotton is fixed on the module housing, and is arranged to avoid a vibration space of a diaphragm of the speaker unit. The present invention effectively improves the performance of a sensitivity curve of the module at high frequencies without modifying the structure of the front acoustic cavity, thus not only increasing the acoustic performance of the module, but also simplifying the structure of the front acoustic cavity of the module.Type: GrantFiled: October 30, 2014Date of Patent: December 18, 2018Assignee: GOERTEK INC.Inventors: Shuai Shao, Chao Xu, Lianwen Shan
