Abstract
(EN)
The present utility model provides a sound producing device, comprising a frame, a vibration system, and a magnetic circuit system. The vibration system comprises a vibrating diaphragm fixed to the frame, a voice coil for driving the vibrating diaphragm to produce sound, and an elastic support assembly fixed to the frame and connected to the end of the voice coil distant from the vibrating diaphragm. The magnetic circuit system comprises a magnet yoke, main magnetic steel fixed to the magnet yoke, secondary magnetic steel located on two opposite sides of the main magnetic steel at an interval respectively, ring-shaped clamping plates stacked on the secondary magnetic steel and spaced apart from the elastic support assembly, and auxiliary magnetic steel respectively fixed to the clamping plates and spaced apart from the main magnetic steel. The elastic support assembly comprises and respectively located on the other two opposite sides of the main magnetic steel. The auxiliary magnetic steel is located on the sides of the clamping plates close to the vibrating diaphragm and is directly opposite to the elastic support assembly separately. Compared with the related art, the sound producing device of the present utility model has good reliability and excellent acoustic performance.

Le présent modèle d'utilité concerne un dispositif de production de son, comprenant un cadre, un système de vibration, et un système de circuit magnétique. Le système de vibration comprend un diaphragme vibrant fixé au cadre, une bobine acoustique pour entraîner le diaphragme vibrant à produire un son, et un ensemble support élastique fixé au cadre et relié à l'extrémité de la bobine acoustique distante du diaphragme vibrant. Le système de circuit magnétique comprend une culasse d'aimant, un acier magnétique principal fixé à la culasse d'aimant, un acier magnétique secondaire situé sur deux côtés opposés de l'acier magnétique principal à un intervalle respectivement, des plaques de serrage annulaires empilées sur l'acier magnétique secondaire et espacées de l'ensemble support élastique, et un acier magnétique auxiliaire fixé respectivement aux plaques de serrage et espacé de l'acier magnétique principal. L'ensemble support élastique comprend et situé respectivement sur les deux autres côtés opposés de l'acier magnétique principal. L'acier magnétique auxiliaire est situé sur les côtés des plaques de serrage à proximité du diaphragme vibrant et est directement opposé à l'ensemble support élastique séparément. Par rapport à l'état de la technique associé, le dispositif de production de son du présent modèle d'utilité présente une bonne fiabilité et d'excellentes performances acoustiques.
