Abstract

The invention relates to a double-voice coil moving-coil loudspeaker which comprises a bracket; a U-shaped cup is fixed in the bracket; a ring-shaped vibrating diaphragm is fixed on the bracket at the position of the U-shaped cup; the U-shaped cup is internally provided with a ring-shaped groove which is internally provided with a magnet; a ring-shaped washer is arranged on the upper surface of the magnet; gaps are arranged between the side wall of the ring-shaped groove and the ring-shaped washer; a large voice coil and a small voice coil are respectively arranged in the gaps; and the ring-shaped vibrating diaphragm covers the ring-shaped washer, and the upper ends of the large voice coil and the small voice coil are fixed with the ring-shaped vibrating diaphragm. The double-voice coil moving-coil loudspeaker is characterized in that the ring-shaped washer is provided with a first vent hole; the U-shaped cup is provided with a second vent hole; and the first vent hole is communicated with the second vent hole for releasing air. The double-voice coil moving-coil loudspeaker has the beneficial effects that 1, the U-shaped cup and the washer are respectively provided with a pressure-relief hole, so that the problem of distortion caused by the air compression at the inner side of the diaphragm can be effectively solved, and the sound quality is further improved; and 2, the double-voice coil moving-coil loudspeaker is simple in structure and beneficial to production, reduces the production cost, and is beneficial to improving the product market competitive power.

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...
