Description

Multi-plane-layer stereo multidirectional-reinforced cone

Technical Field

The utility model relates to a speaker sound basin technical field especially relates to a sound basin of three-dimensional multidirectional enhancement of many plane layers.

Background

The loudspeaker is used as a device capable of converting electric energy into sound energy, is widely applied to mobile terminals such as mobile phones, computers, PADs and the like, and the quality of the performance of the loudspeaker directly influences the sound emission effect of each terminal device matched with the loudspeaker. The loudspeaker structure comprises a magnetic circuit system and a vibration system, wherein the vibration system comprises a sound cone and a voice coil, and the voice coil can do reciprocating cutting movement of magnetic lines of force under the action of an electromagnetic field after receiving a current signal of an external circuit, so as to drive the sound cone to vibrate, further radiate sound waves to the outside, and therefore the conversion from electric energy to sound energy is completed. It can be seen from the above description that the cone is one of the key components for the vibration and sound production of the speaker, especially the strength of the cone, and the existing method for increasing the strength of the cone is to increase the strength by increasing the thickness, which will bring about the increase of the weight of the cone at the same time, so that the transient response, intermodulation distortion, harmonic distortion, efficiency, etc. of the speaker are greatly deteriorated, and the improvement of the sound quality cannot be broken through. The reinforcing ribs are additionally arranged, the existing reinforcing rib mode is one-way, and the strength is enhanced in one direction only; the one-way reinforcement can not be well applied to the plane sound cone, so that the performance of the plane sound cone is greatly improved.
