Abstract

The invention discloses a loudspeaker with multiple sound cones. The loudspeaker improves the original sound playback clarity of the loudspeaker and has higher sensitivity. The loudspeaker with the multiple sound cones comprises a cone frame and a sound cone assembly arranged on the cone frame, the sound cone assembly comprises a central sound cone and a plurality of outer sound cones, the outer sound cones are sequentially arranged in the circumferential direction of the central sound cone, and the loudspeaker further comprises a central driving mechanism and a plurality of outer driving mechanisms arranged on the periphery of the central driving mechanism in a surrounding mode. The central cone is driven by the central driving mechanism to vibrate and produce sound, each external cone isdriven by one external driving mechanism to vibrate and produce sound, and the central driving mechanism comprises a central voice coil connected with the central cone and a central magnetic circuitsystem used for driving the central voice coil. Each external driving mechanism comprises an external voice coil connected with the corresponding external voice cone, an external positioning support chip sleeving on the corresponding external voice coil, 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 multi-cone loudspeaker, in particular to a multi-cone loudspeaker without a positioning support piece that can input multi-channel audio input signals. Background technique

[0002] The sound cone used by the existing traditional speakers without positioning struts is generally dish-shaped, and the sound cone is connected with a voice coil to form a speaker vibration system without positioning struts. 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 loudspeaker vibration system is formed, which can be applied to multi-channe...
