Title
(EN) Loudspeaker
(ZH) 扬声器
Abstract
(EN) The utility model provides a loudspeaker, comprising a basin frame, a vibration system fixed on the basin frame and a magnetic circuit system, and the vibration system comprises an upper vibrating diaphragm fixed on the basin frame, a voice coil driving the upper vibrating diaphragm to sound, a flexible circuit board electrically connecting the voice coil with an external electric signal, and a framework fixed on the flexible circuit board and supporting the upper vibrating diaphragm. The flexible circuit board comprises a first fixing arm and a second fixing arm which are arranged at an interval; wherein the framework comprises a supporting table and a side wall which extends from the bottom of the supporting table to the second fixing arm, the flexible circuit board comprises a main body part fixed on the side wall of the framework and a bending part which bends and extends from the main body part to the supporting table of the framework, and the flexible circuit board further comprises a supporting piece which is attached to one side, close to the vibrating diaphragm, of the second fixing arm. The supporting piece is additionally arranged at the bending position of the flexible circuit board, so that the flexible circuit board is bent into any shape and does not rebound, and high stability and consistency are achieved.
(ZH) 本实用新型提供一种扬声器,包括盆架、固定于盆架的振动系统及磁路系统,振动系统包括固定于盆架的上振膜、驱动上振膜发声的音圈、电连接音圈与外部电信号的柔性线路板以及固定于柔性线路板并支撑上振膜的骨架。柔性线路板包括间隔设置的第一固定臂和第二固定臂;骨架包括支撑台及自支撑台底部朝向第二固定臂延伸的侧壁,柔性线路板包括固定于骨架侧壁的主体部及自主体部朝向骨架支撑台弯折延伸的弯折部,所述柔性线路板还包括贴设于所述第二固定臂靠近所述振膜一侧的支撑件。本实用新型通过在柔性线路板折弯处增加支撑件,以将柔性线路板折弯成任意形状,且不会回弹,具有很高的稳定性和一致性。
