Abstract

The invention provides a novel double-moving-coil type loudspeaker which comprises a support, a lower clamping plate is fixed in the support, a vibration diaphragm is fixed on the support located on the lower clamping plate, two grooves are formed in the lower clamping plate, magnets are arranged in the two grooves respectively, washers are arranged on the upper surfaces of the magnets, gaps are formed between the side walls of the grooves and the washers, a large voice coil and a small voice coil are arranged in the gaps respectively, the vibration diaphragm covers the washers, and the upper end of the large voice coil and the upper end of the small voice coil are fixedly connected with the vibration diaphragm. The novel double-moving-coil type loudspeaker is characterized in that magnetic circuits of the large voice coil and the small voice coil are double inter magnetic circuits or double outer magnetic circuits in the lower clamping plate, a first vent hole is formed in the lower clamping plate, a second vent hole is formed in the support, and the first vent hole is communicated with the second vent hole for air leakage to enable the air pressure in the vibration diaphragm and the air pressure of the outside to be consistent. The novel double-moving-coil type loudspeaker effectively solves the distortion problem caused by compression of space in and out of the diaphragm, the sound quality effect is improved, and product quality is improved.

Description

【Technical field】 [0001] The invention relates to an electro-acoustic conversion device, in particular to a moving coil loudspeaker with inner and outer double voice coils. 【Background technique】 [0002] Existing loudspeakers generally have a single voice coil structure, and when a single voice coil drives the diaphragm to move, the rigidity requirements for the diaphragm are relatively high. Because the current material technology cannot meet the requirements of high rigidity, light weight and good damping of Gu Gu membrane, it is prone to split vibration and cause distortion. As a result, the performance of the loudspeaker cannot be improved all the time. [0003] The National Patent Office has published the publication numbers "CN201657287U, CN201854415U". The patent document discloses a speaker structure with double magnetic steel and double voice coils. The advantages of thinner and lighter products. But not much improvement to resolve distortion. And the double ma...
