Abstract
(EN)
Provided is a loudspeaker, comprising a basket, and a magnetic circuit system and a vibration system arranged in the basket. The vibration system comprises a surround fixed on the basket, a dome fixed on the center of the surround, and a voice coil connected below the dome, wherein the dome comprises a first dome and a second dome stacked in sequence, the second dome comprises a body part, and a plurality of bulges extending from the body part towards the magnetic circuit system, a gap is formed between adjacent bulges, the bulge comprises a bottom surface close to the magnetic circuit system, the voice coil abuts against the bottom surface, and a leakage channel is formed between the gap and the second dome. Compared with related technology, the loudspeaker provided in the present invention can avoid the impact of unbalanced internal and external air pressures of the voice coil on the loudspeaker performance.

L'invention concerne un haut-parleur, comprenant un saladier, et un système de circuit magnétique et un système de vibration agencés dans le saladier. Le système de vibration comprend un entourage fixé sur le saladier, un dôme fixé sur le centre de l'entourage, et une bobine acoustique connectée au-dessous du dôme. Le dôme comprend un premier dôme et un second dôme empilés en séquence; le second dôme comprend une partie corps, et une pluralité de bosses s'étendent depuis la partie corps vers le système de circuit magnétique, un espace étant formé entre les bosses adjacentes; la bosse comprend une surface inférieure proche du système de circuit magnétique; la bobine acoustique vient en butée contre la surface inférieure; et un canal de fuite est formé entre l'espace et le second dôme. Par rapport à la technologie associée, le haut-parleur de la présente invention peut éviter l'impact de pressions d'air internes et externes non équilibrées de la bobine acoustique sur les performances du haut-parleur.
