Abstract

PURPOSE:To make an adhesive unnecessary to prevent degradation of the vibration performance and damage of the external appearance due to the adhesive, by fitting a casing to a speaker frame mechanically. CONSTITUTION:A step part is formed in the lower end part of a casing 7, and a step part is formed also in the upper end part of a speaker frame 1. In respect to the casing 7 which is not fitted the speaker frame yet, the inside diameter to the upper face of the step part is slightly smaller than the outside diameter to the upper face of the step part of the frame 1, and the step part is elastic at least. By this constitution, step parts of the casing 7 and the speaker frame 1 are fitted to fit the casing 7 to the speaker frame 1.
