Abstract
(EN)
The present utility model provides a speaker, comprising a basket, and a magnetic circuit system and a vibration system which are provided within the basket. The vibration system comprises a folded ring fixed on the basket, a dome fixed at the center of the folded ring, and a voice coil connected to the dome. The dome comprises an inner surface close to the magnetic circuit system, and grooves formed by recessing from the inner surface in a direction away from the magnetic circuit system. The voice coil is fixedly connected to the inner surface, and leakage channels are formed between the grooves and the voice coil. Compared with the related art, the speaker provided by the present utility model is able to promote airflow circulation in the voice coil, improving the performance of the speaker.

Le présent modèle d'utilité concerne un haut-parleur, comprenant un saladier, et un système de circuit magnétique et un système de vibration qui sont disposés à l'intérieur du saladier. Le système de vibration comprend une bague pliée fixée sur le saladier, un dôme fixé au centre de la bague pliée, et une bobine mobile reliée au dôme. Le dôme comprend une surface interne proche du système de circuit magnétique, et des rainures formées en retrait à partir de la surface interne dans une direction opposée au système de circuit magnétique. La bobine mobile est reliée de manière fixe à la surface interne, et des canaux de fuite sont formés entre les rainures et la bobine mobile. Par rapport à l'état de la technique associé, le haut-parleur fourni par le présent modèle d'utilité est capable de favoriser la circulation de flux d'air dans la bobine mobile, ce qui permet d'améliorer les performances du haut-parleur.
