Title (EN) ELECTROACOUSTIC DEVICE AND MOBILE TERMINAL
(FR) DISPOSITIF ÉLECTROACOUSTIQUE ET TERMINAL MOBILE
Abstract:
(EN) An electroacoustic device and a mobile terminal (900) are provided. The electroacoustic device may include a box (10, 10c, 10d, 40) defining an opening (11, 421); an electroacoustic component (20) including a frame (21, 21c, 21d, 60), a vibrating membrane (22, 50) and a driving assembly (23, 70), wherein the frame is installed inside the box (10, 10c, 10d, 40), the vibrating membrane (22, 50) is assembled on the frame (21, 21c, 21d, 60) and covers the opening (11, 421), the frame (21, 21c, 21d, 60) and the vibrating membrane (22, 50) define a chamber (24, 45), the driving assembly (23, 70) is configured to drive the vibrating membrane (22, 50) to vibrate, and the frame (21, 21c, 21d, 60) defines a leaking channel (211, 211c, 211d, 61); and partition nets (30, 80) set inside the box (10, 10c, 10d, 40), wherein a space between the electroacoustic component (20) and the box (10, 10c, 10d, 40) is divided into cavities (12, 46) by the partition nets (30, 80), at least one cavity (12, 46) is filled with sound absorption material (13, 47), and the cavities (12, 46) are communicated with the chamber (24, 45) through the leaking channel (211, 211c, 211d, 61).
(FR) L'invention concerne un dispositif électroacoustique et un terminal mobile (900). Le dispositif électroacoustique peut comprendre une boîte (10, 10c, 10d, 40) définissant une ouverture (11 411); un composant électroacoustique (20) comprenant un cadre (21, 21c, 21d, 60), une membrane vibrante (22, 50) et un ensemble d'entraînement (23, 70), le cadre étant installé à l'intérieur de la boîte (10, 10c, 10d, 40), la membrane vibrante (22, 50) est assemblée sur le cadre (21, 21c, 21d, 60) et recouvre l'ouverture (11 421), le cadre (21, 21c, 21d, 60) et la membrane vibrante (22, 50) définissent une chambre (24, 45), l'ensemble d'entraînement (23, 70) étant configuré pour entraîner la membrane vibrante (22, 50) à vibrer, et le cadre (21, 21c, 21d, 60) définit un canal de fuite (211, 211c, 211d, 61); et des filets de cloisonnement (30, 80) placés à l'intérieur de la boîte (10, 10c, 10d, 40), un espace entre le composant électroacoustique (20) et la boîte (10, 10c, 10d, 40) étant divisé en cavités (12, 46) par les filets de cloisonnement (30, 80), au moins une cavité (12, 46) est remplie d'un matériau d'absorption acoustique (13, 47), et les cavités (12, 46) sont en communication avec la chambre (24, 45) à travers le canal de fuite (211, 211c, 211d, 61).
