Abstract

The invention relates to a dual-surround diaphragm, a loudspeaker and a mobile terminal. The dual-surround diaphragm comprises: an inner dome, an inner surround, an outer dome and an outer surround. The dual-surround diaphragm is used in the loudspeaker. By means of a multi-surround principle, a diaphragm is provided with the inner surround and the outer surround so that the area of the surround is increased. Thus, the proportion of low frequency is increased so as to obtain a good reductive effect and achieve pleasant sound. The loudspeaker is provided inner and outer voice coils and the inner and outer domes so as to increase the vibration amplitude of the inner dome. The vibration amplitude of the inner dome directly affects the volume of the loudspeaker, thereby improving the loudspeaker volume.

Description

technical field [0001] The present application relates to the technical field of loudspeakers, in particular to a double-fold ring diaphragm, a loudspeaker and a mobile terminal. Background technique [0002] Loudspeakers in the prior art include: cone loudspeakers and dome loudspeakers. The cone speaker has the characteristics of simple structure and high energy conversion efficiency, but due to the structural defects of the cone speaker, the directivity index of the cone speaker is often unsatisfactory, and the volume of the cone speaker is large, which is not suitable for In highly integrated mobile terminals. With the continuous maturity and development of audio technology and the development of miniaturization and integration of mobile terminals, the requirements for portability, ultra-thin and ultra-light of Internet access products are also getting higher and higher. Due to the small diaphragm diameter design of the dome speaker, the small diameter diaphragm has a m...
