Loudspeaker

Abstract

The invention provides a loudspeaker. The loudspeaker comprises a basin frame, a vibration system and an elastic supporting piece. The vibration system comprises a first vibrating diaphragm and a voice coil. The elastic support member comprises a flexible circuit board which is fixed on the basin frame and supports the voice coil. the flexible circuit board comprises a first fixing part connectedwith the voice coil, a second fixing part connected with the basin frame and an elastic arm connected with the first fixing part and the second fixing part; the elastic arm comprises a first part connected with the first fixing part, a second part connected with the second fixing part and a third part connected with the first part and the second part in a bent mode. The third part is closer to thefirst vibrating diaphragm than the first part and the second part; and the tail end of the first part and the tail end of the second part are respectively bent and extend towards the direction closeto the first vibrating diaphragm and are connected to the two ends of the third part. The loudspeaker provided by the invention is simple in structure, high in vibration performance and good in acoustic performance.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of sound and electricity, in particular to a loudspeaker. [0003] 【Background technique】 [0004] With the development of electronic technology, in order to meet the multi-functional and high-quality sound requirements of various audio equipment and information communication equipment, higher requirements are put forward for the acoustic performance of speakers.
