Abstract
(EN)
A speaker module relates to the technical field of electroacoustic products, and comprises a lower module casing, an upper module casing and a steel sheet which are successively combined together. A speaker monomer is contained in a space enclosed by the lower module casing, the upper module casing and the steel sheet. The speaker monomer, the upper module casing and the steel sheet together enclose a front sound cavity of the module. The front sound cavity is in communication with a sound outlet hole of the module, and the sound outlet hole is located on a side part of the speaker monomer. A sheet is adhered inside the steel sheet, the thickness of the sheet being about 0.1 mm ~ 0.2 mm and the material of the sheet being a soundproof material. The present speaker module solves the technical problem of the poor intermediate and high frequency performance of the speaker module in the prior art. The speaker module has a good intermediate and high frequency performance, a high overall acoustic performance, a thin thickness, and also a good stability, and a long service life.

La présente invention concerne un module de haut-parleur qui a pour objet le domaine technique des produits électroacoustiques et qui consiste en un boîtier de module inférieur, un boîtier de module supérieur et une feuille d'acier qui sont successivement combinées ensemble. Un haut-parleur monomère est contenu dans un espace entouré par le boîtier de module inférieur, le boîtier de module supérieur et la feuille d'acier. Le haut-parleur monomère, le boîtier de module supérieur et la tôle d'acier entourent ensemble une cavité sonore frontale du module. La cavité sonore frontale est en communication avec un orifice de sortie de son du module et l'orifice de sortie de son est situé sur un partie côté du haut-parleur monomère. Une feuille est collée à l'intérieur de la tôle d'acier, l'épaisseur de la feuille étant d'environ 0,1 mm ~ 0,2 mm et le matériau de la feuille étant un matériau insonorisant. Le présent module de haut-parleur résout le problème technique de faible performance à des fréquences intermédiaires et élevées du module de haut-parleur dans l'état de la technique. Le module de haut-parleur présente une bonne performance à des fréquences intermédiaires et élevées, une performance acoustique globale élevée, une faible épaisseur et également une bonne stabilité et une longue durée de vie.
