Definitions
- the ground feed point is provided on the upper cover plate 10, and a conductive foam 60 is provided between the first steel sheet 40 and the sounding monomer 30.
- the upper cover plate 10 is provided with a second steel plate connected to the ground feed point.
- the lower cover plate 20 is provided with a through hole 22 so that the fixing portion 42 of the first steel sheet 40 is at least partially exposed, and then a conductive connecting member 70 is provided between the fixing portion 42 and the second steel sheet 50 to make the conduction
- One end of the connecting piece 70 is connected to the second steel sheet 50, and the other end extends into the through hole 22 to connect to the fixing portion 42 to realize the connection between the fixing portion 42 and the ground feed point, thereby realizing the first steel sheet 40 and the sound
- the connection between the single unit 30 and the grounding feed point uses this technical solution to solve the technical problems of large and unstable resistance and fluctuations in overall conductivity when the sound generating unit 30 is connected to the whole terminal in the prior art to be connected to the ground.
- the conductive connecting member 70 can be a spring or a spring thimble, and the resistance values of the spring and the spring thimble are relatively low and stable.
- the spring is selected, the space of the rear cavity can be greatly saved, which is beneficial to improve the low-frequency acoustic performance; when the spring thimble is selected, the contact between the spring thimble and the fixed part 42, and the spring thimble and the second steel sheet 50 can be more stable. , To prevent the overall continuity from fluctuating easily.
- the hole wall of the conductive hole 22 extends toward the second steel sheet 50 to form a positioning portion 23, and one end of the conductive connector 70 is located in the positioning portion 23.
- One end of the conductive connector 70 is received in the positioning portion 23, and the conductive connector 70 is basically positioned, which facilitates the smooth progress of the assembly work of the speaker box, and basically ensures that the conductive connector 70 and the fixing portion 42, the second The contact stability of the steel sheet 50.
- the enclosure 52 and the upper cover plate 10 are injection-molded to ensure the stability of the connection between the second steel sheet 50 and the upper cover plate 10, and the main body portion ensures that the second steel sheet 50 can be connected to each other.
- the connector 70 makes full contact.
Abstract
Le présent modèle d'utilité concerne une enceinte de haut-parleur et un dispositif terminal. L'enceinte de haut-parleur comprend une plaque de couverture supérieure, une plaque de couvercle inférieure formant une cavité de réception avec la plaque de couvercle supérieure, un monomère de production de son reçu dans la cavité de réception, une première feuille d'acier fixée sur la plaque de couvercle inférieure, et une mousse conductrice disposée entre la première feuille d'acier et le monomère de production de son. Une ouverture correspondant au monomère de production de son est formée sur la plaque de couverture inférieure, la première feuille d'acier comprend un premier corps principal recouvrant l'ouverture et une partie fixe formée en s'étendant du premier corps principal à la plaque de couverture inférieure, et la partie fixe et la plaque de couverture inférieure sont moulées par injection. Une seconde feuille d'acier connectée à un point d'alimentation de mise à la terre est disposée de manière fixe sur la plaque de couverture supérieure, un trou d'interconnexion est formé sur la plaque de couvercle inférieure, et la partie fixe est au moins partiellement exposée au moyen du trou d'interconnexion. L'enceinte de haut-parleur comprend en outre un connecteur de conduction. Une extrémité du connecteur de conduction est reliée à la seconde feuille d'acier, et l'autre extrémité de celui-ci s'étend dans le trou d'interconnexion pour être reliée à la partie fixe. L'application de la solution technique, les problèmes techniques de l'état de la technique selon lesquels, lorsque le monomère de production de son est en communication avec la machine complète à mettre à la terre, la résistance est importante et instable, et la conductivité globale fluctue.
