Problems solved by technology

However, due to its special diaphragm fold structure, it does not directly radiate sound waves to the front, but laterally squeezes and ejects airflow to radiate sound waves. In addition, sound waves are in a state of lateral extrusion and collision, which will cause phase distortion when sound waves of the same wavelength collide, and harmonic distortion will occur when high-order harmonics of integer multiples collide

Abstract

The present invention provides a multi-pole engine array system and a loudspeaker. The multi-pole engine array system comprises a plurality of engine assemblies distributed in an annular array, wherein the plurality of the engine assemblies are fixed inside the annular loudspeaker through a mounting seat arranged in a casing of the annular loudspeaker; each engine component comprises a magnet conductive plate and a magnet body arranged in the magnet conductive plate; a magnetic field is formed between the magnet body and the magnet conductive plate; and the plurality of engine components are arrayed coaxially and annularly along the periphery of the mounting seat to form a multi-pole magnetic field having a plurality of magnetic pole directions. According to the multi-pole engine array system and the loudspeaker in the invention, a multi-pole magnetic field surrounded by a plane is formed via a monopole equal-magnetic-plane magnetic field through a multi-pole manner so that each pole surface of an inductive diaphragm radiates sound waves with controllable power to any configurable angular space at different angles; the diaphragms are driven to vibrate at the same time to form moreaudio information, thereby improving the power and efficiency of the loudspeaker; and the reaction speed is faster.

Description

technical field [0001] The invention relates to the technical field of electric loudspeakers, in particular to a multi-pole engine array system and a loudspeaker. Background technique [0002] Traditional mid-range and high-pitched speaker units generally include cone speakers, dome speakers, horn speakers, ribbon speakers, flat speakers, etc. Among them, the wave front of the radiation wave of the cone speaker, the dome speaker, and the horn speaker belongs to the spherical wave. The wave front of the spherical wave changes sharply from the center to the edge, and the driving force generated by the voice coil is not flat on the diaphragm. , but it is first transmitted to the edge of the diaphragm (individual midrange speakers are the center of the diaphragm), and then gradually transmitted to other parts of the entire diaphragm, which will inevitably take a certain amount of time. Therefore, at a certain moment, the force on each part of the diaphragm will be uneven, and i...
