Electromagnetism transient magnetic loudspeaker

Abstract

The invention provides an electromagnetism transient magnetic loudspeaker, which comprises a vibrating diaphragm, wherein a magnetizer is arranged on the vibrating diaphragm; an electromagnetic device is arranged on an opposite position of the magnetizer, and comprises a coil opposite to the magnetizer, and a magnetic bar; and the magnetic bar penetrates through an inner opening of the coil so as to be opposite to the magnetizer. The weight of the vibrating diaphragm is reduced; due to the removal of a voice coil, the axial movement of the voice coil in a magnetic gap is avoided; an electromagnetic type power structure is adopted, so that compared with an existing permanent magnet, the magnetic density is higher, a sound signal can be performed at high speed; a plane vibrating diaphragm design is adopted, so that voice frequency can be parallely transmitted, the defect of emission of voice frequency of a bowl type vibrating diaphragm is overcome, and the sound signal can be highly positioned; and a nickel ring has the characteristics of magnetization, inoxidizability, acid and alkali corrosion and the like, so that the service life of the loudspeaker is greatly prolonged, the problems that the magnetic force of a permanent magnet is reduced, and the tone quality is affected are solved, and graceful sound with high sound quality, clearness, enriched detail and wonderful layering performance is realized.

Description

technical field [0001] The invention relates to the field of loudspeakers, in particular to an electromagnetic transient magnetic loudspeaker which uses electricity to generate an electromagnetic field. Background technique [0002] A loudspeaker is a device that converts electrical energy into sound, therefore, includes such as figure 1 The electromagnetic speaker shown and the figure 2 The electrodynamic loudspeaker shown. [0003] For electromagnetic speakers, the main components include permanent magnet 1, needle-shaped soft iron 2, coil 3, paper plate 4 (or diaphragm) and basin frame 5. The principle of sound generation is: the sound source signal power passes through the coil After 3, the needle-shaped soft iron 2 connected to the paper tray 4 will be magnetized, and the polarity of the needle-shaped soft iron 2 will be changed according to the positive and negative changes of the sound source signal power, thus making the magnetized needle-shaped soft iron 2 Attra...

AI Technical Summary

Problems solved by technology

[0005] The invention provides an electromagnetic transient magnetic loudspeaker, the purpose of which is to solve the weight of the diaphragm load coil, directly reduce the overall weight of the diaphragm, and at the same time avoid the noise, distortion or damage to the voice coil caused by the friction of the magnetic gap in the magnet. question
