Summary:Provided is a speaker including: a frame connected to a magnetic circuit; a diaphragm connected to the outer circumference of the frame; a voice coil connected to the diaphragm and having part arranged in a magnetic gap of the magnetic circuit; and a dust cap connected to least one of the diaphragm and the voice coil. The dust cap has dome cross section of elliptical arc shape. Thus, it is possible to improve high end feature of the speaker and increase the band. La présente invention concerne un haut-parleur qui comprend : - un cadre relié à un circuit magnétique, - un diaphragme relié à la circonférence externe du cadre, - une bobine vocale reliée au diaphragme et ayant une partie agencée dans un intervalle magnétique du circuit magnétique, - un bouchon de poussière relié au diaphragme ou à la bobine vocale. Le bouchon de poussière possède une section transversale de dôme de la forme d'arc elliptique. Il est donc possible d'améliorer la caractéristique de haut niveau du haut-parleur et d'augmenter la bande.
