Patent KR-20220144463-A (KR)
Inventor: YOON DAE HWAN
IPC: H04R1/28
Filed: 2021-04-20
Abstract: The present invention relates to a speaker frame for reducing the intensity of internally reflected sound. A speaker is an acoustic device that produces sound by generating waves in the air by vibrating a diaphragm. Sound does not only go out of the speaker's diaphragm, but also enters the speaker's inside. According to the present invention, the speaker frame for reducing the intensity of internally reflected sound allows the angle of a frame surface facing the diaphragm to be designed so that primarily reflected sound does not touch the diaphragm, thereby reducing a phenomenon in which the sound reflected by the frame affects the vibration of the diaphragm.
