Abstract

The invention discloses a multi-cone small loudspeaker without a positioning support chip. The loudspeaker improves the original sound replay definition of the loudspeaker, has better bass and directivity width of the loudspeaker, and has higher sensitivity and smaller distortion. The multi-cone small loudspeaker comprises a cone frame and a sound cone assembly arranged on the cone frame, the sound cone assembly comprises a central sound cone and an outer sound cone, and the small loudspeaker further comprises a central driving mechanism used for driving the central sound cone to vibrate and aplurality of outer driving mechanisms used for driving the outer sound cone to vibrate. The external driving mechanisms are arranged on the periphery of the central driving mechanism, and the centraldriving mechanism comprises a central voice coil connected with the central voice basin and a central magnetic circuit system used for driving the central voice coil. Each external driving mechanismcomprises an external voice coil connected with the corresponding external cone and an external magnetic circuit system used for driving the external voice coil.

Description

technical field

[0001] The invention belongs to the field of loudspeakers, and relates to a small multi-cone loudspeaker, in particular to a multi-cone small loudspeaker without a positioning support piece, which can input multiple audio input signals. Background technique

[0002] The existing traditional small speakers without positioning struts usually use a disc-shaped sound cone, which is connected with a voice coil to form a speaker vibration system without positioning struts. This kind of non-positioning strut speaker can only be used in single Signal input, single audio signal input has limitations on the original sound reproduction, and the combination of a single voice coil and the sound cone has high requirements on the rigidity of the sound cone material. Although, the voice coil of this speaker can also use a voice coil that can input multiple signals. This voice coil is formed by stacking multiple sets of coils from the inside to the outside. Above, a loudspea...
