Title
(EN) Loudspeaker
(ZH) 扬声器
Abstract
(EN) The utility model provides a loudspeaker comprising a frame, a vibration system and a magnetic circuit system, the vibration system comprises a diaphragm, a voice coil and an elastic support member, one end of the elastic support member is fixed relative to the frame, the other end of the elastic support member is connected with the diaphragm through a skeleton, and the elastic support member comprises a flexible circuit board and an auxiliary diaphragm. Wherein the flexible circuit board comprises a first fixing part, a second fixing part and a deformation part, the second fixing part and thefirst fixing part are arranged at an interval, the deformation part is connected with the first fixing part and the second fixing part, the auxiliary vibrating diaphragm comprises a holding part, a folding ring part and a combining part, and the folding ring part and the combining part extend inwards from the holding part in sequence. The combination part and the second fixing part are both fixedon the surface of one side, far away from the diaphragm, of the framework, and the second fixing part is located between the combination part and the voice coil. According to the loudspeaker of the utility model, on one hand, the thickness of the loudspeaker along the vibration direction can be effectively reduced, and on the other hand, under the condition that the thickness of the loudspeaker along the vibration direction is fixed, the amplitude of a vibration system can be improved.
(ZH) 本实用新型提供了一种扬声器,其包括盆架、振动系统及磁路系统,振动系统包括振膜、音圈以及弹性支撑件,弹性支撑件的一端相对盆架固定,其另一端通过骨架与振膜连接,弹性支撑件包括柔性电路板及辅助振膜,柔性电路板包括第一固定部、与第一固定部间隔设置的第二固定部及连接第一固定部和第二固定部的形变部,辅助振膜包括固持部以及自固持部向内依次延伸形成的折环部和结合部,结合部环绕磁路系统,结合部和第二固定部均固定于骨架远离振膜一侧的表面,且第二固定部位于结合部和音圈之间。本实用新型的扬声器一方面可以有效降低扬声器沿振动方向的厚度,另一方面,在扬声器沿振动方向的厚度一定的情况下,可以提高振动系统的振幅。
