Abstract
The present disclosure provides a sound-producing unit having a flexible printed circuit board that includes a first fixing portion, a first elastic arm extending from the first fixing portion along a first direction, a second elastic arm extending from the first elastic arm along a second direction, and a second fixing portion connected to the second elastic arm. By providing two elastic arms extending in different directions, the first fixing portion and the second fixing portion are positioned on two different planes, which fully utilizes the length of the elastic arms of the flexible printed circuit board. The elastic arms have a three-dimensional structure, which maximizes the elastic support force of the flexible printed circuit board, enhances the vibration sensitivity of the sound-producing unit, and buffers the pressure on the elastic arms, thereby improving the service life of the flexible printed circuit board.
