Problems solved by technology

[0002] The quality of the speaker's structure determines its sound quality. Now the speakers on the market have their own characteristics, and a single sound film with a traditional structure is generally used to produce sound. The range of sound performance is not wide enough, that is, the high and low frequencies cannot be well coordinated. Under such circumstances, it is necessary to develop a speaker with a new structure to better improve the sound quality

Abstract

The invention discloses a loudspeaker with a novel double-magnetic structure. The loudspeaker comprises a first voice diaphragm, a second voice diaphragm, a first voice coil, a second voice coil, a first copper ring, a second copper ring, a first concentrating flux plate, a second concentrating flux plate, a third concentrating flux plate, a fourth concentrating flux plate, a first magnet, a second magnet, an annular connecting block, a support, tuning paper and a PCB. A first concentrating flux plate is arranged on the first magnet, a third concentrating flux plate is arranged below the firstmagnet, the second magnet is arranged on the periphery of the first magnet, and the first magnet and the second magnet are fixed through an annular connecting block. The invention follows the acoustic principle so that the structure is excellent. The key point is that upper and lower voice diaphragms simultaneously pronounce; the two voice diaphragms are matched in a large-small mode, the defectsof low frequency and high frequency can be overcome at the same time, the frequency response range of the loudspeaker is wider, meanwhile, the magnetic circuit design enables the magnetic field intensity of the two voice diaphragms to be higher, the support and the magnetic set part adopt the injection molding process, and therefore the electroacoustic performance is more excellent, the process is simplified, and consistency is better.

Description

technical field [0001] The invention relates to an electroacoustic device, in particular to a novel double magnetic structure loudspeaker. Background technique [0002] The quality of the speaker's structure determines its sound quality. Now the speakers on the market have their own characteristics, and a single sound film with a traditional structure is generally used to produce sound. The range of sound performance is not wide enough, that is, the high and low frequencies cannot be well coordinated. Under such circumstances, it is necessary to develop a speaker with a new structure to better improve the sound quality. Contents of the invention [0003] The technical problem to be solved by the invention is a new double magnetic structure loudspeaker, which is easy to operate and can effectively improve the sound quality. [0004] The present invention is achieved through the following technical solutions: a novel double magnetic structure loudspeaker, comprising a first...
