Multiple engine array system and speaker

Abstract

A multiple engine array system and speaker. The multiple engine array system includes at least two engine components, the at least two engine components are mounted at the bottom of the basin rack ofthe loudspeaker, each of the engine components includes a voice coil provided with a voice coil skeleton and a magnetic circuit system for providing a magnetic field to the voice coil, the magnetic circuit system comprises a magnetic bowl, a magnetic and a magnetic conductive plate , the magnetic bowl is arranged at the bottom of the basin rack, the magnetic and the magnetic conductive plate arearranged in the magnetic bowl, a magnetic gap is formed between the magnetic bowl and the magnet and the magnetic conductive plate, the voice coil is suspended in the magnetic gap, and the cross-sectional shapes of the voice coil and the magnetic circuit system are rectangular. The invention has wide application range, can effectively reduce power consumption, improve loudspeaker efficiency, reduce resonant frequency, improve heat dissipation effect, and can reduce various distortions such as non-linear distortion through cooperation and restriction of a plurality of engine components.

Description

technical field [0001] The invention relates to the technical field of electric loudspeakers, in particular to a multi-engine array system and a loudspeaker. Background technique [0002] Most of the traditional speaker engines are driven by a single engine, and the shape of the engine is mostly circular. This kind of traditional engine generally adopts the external magnetic type, which consists of upper and lower magnetic plates (T iron and washer), magnets (mainly iron Oxygen body), voice coil (wire winding) and skeleton (handmade by DuPont glass fiber cloth, aluminum alloy reel or cardboard reel). For loudspeakers with larger diameters, traditional single-engine loudspeakers need to change the size of the diaphragm and voice coil, especially the size, weight, cost, and mold of the magnets in the engine, making it difficult to achieve large-diameter loudspeakers. Produce. [0003] Plus, poor engine cooling can cause a host of problems with the speakers. For example, mag...

Problems solved by technology

When this happens, its linear motion is not as accurate as the piston in the cylinder, approaching or exceeding this range will cause nonlinear motion and then generate nonlinear distortion and harmonic distortion; the second is the voice coil, voice coil skeleton and The strut and diaphragm connected to the top of the voice coil bobbin are in a semi-suspension state. At the same time, due to the elasticity of the strut and diaphragm, the voice coil will have a non-linear offset during movement.

[0006] In addition, traditional single-engine speakers will produce various distortion problems, such as harmonic distortion and intermodulation distortion caused by the nonlinear vibration of the voice coil across the magnetic gap, output power and efficiency η caused by the back electromotive force of the voice coil o Loss, non-linear distortion caused by uneven distribution of engine magnetic force and current BLI, harmonic distortion, group delay, phase distortion etc.
