Loudspeaker unit and loudspeaker device

Abstract

The invention provides a loudspeaker unit and a loudspeaker device. The main body of the loudspeaker unit is a rectangular basin structure, including a suspension system, a magnetic circuit system with an annular magnetic gap and a basin frame connecting the suspension system to the magnetic circuit system; the basin frame accommodates the suspension system and the magnetic circuit system, and themagnetic circuit system is fixed in the basin frame; the suspension system comprises a vibrating diaphragm and at least one voice coil connected to the bottom of the vibrating diaphragm; the magneticcircuit system comprises at least one magnetic circuit component matching the voice coil; one end of the voice coil is connected to the vibrating diaphragm through a voice coil framework, and the other end of the voice coil is placed in the annular magnetic gap formed by the magnetic circuit component; the voice coil can perform piston reciprocating vibration along the axial direction in the annular magnetic gap to push the vibrating diaphragm to vibrate to emit sound. The invention adopts a plurality of engines to drive the same vibrating diaphragm vibrate, and the vibration is more balancedand stable, which can reduce nonlinear vibration, and can control the size of the impedance RE; the invention has wide application range and beautiful structure, and can realize sufficient heat dissipation.

Description

technical field [0001] The present invention relates to the technical field of electrodynamic speakers, in particular to a speaker unit and a speaker device. Background technique [0002] As a key component of audio equipment, the quality of the speaker unit directly affects the sound quality of the audio equipment. So far, the shape and structure of each component of the traditional speaker unit (especially the mid-bass speaker unit) are circular structures. For example, most of the diaphragms are conical diaphragms. The effective area of ​​the conical diaphragms is small, and the sound energy conversion efficiency is poor. At the same time, when the circular diaphragms move, they will generate radial and axial split vibrations, which will generate a large number of vibrations. The interfering harmonics form harmonic distortion. In addition, most of the existing loudspeakers are driven by a single engine and adopt an external magnetic structure, and the voice coil is prone...

Problems solved by technology

The intersection area S of adjacent wave fronts in the spherical waves radiated between multiple speakers presents an exponential gradient in four directions, and the intersection area cannot be weakened after multiple wave front arrays, that is, multiple spherical waves cannot be coupled in an orderly manner , it is easy to form a chaotic sound field, produce interference, and affect the effective coverage of sound
