Description
また、振動板20が大きく振動系に重量がある場合、磁気ギャップ内の所定位置にボイスコイルを保つ配慮はなされておらず、こすり等が生じるおそれがあった。
図1は本発明の第1実施例の内部構造を示す断面図、図2は図1中丸で囲んだA部分の拡大断面図、図3は平面図、図4は図3中丸で囲んだA部分の拡大図を示す。
図8は本発明の参考例1を示す。この参考例では、振動板2の一端部と、フレーム1の長辺側の一端部とを可撓性を有する断面ほぼくの字の樹脂、織布、皮革、金属等からなる連結部材16にて接着剤を介して連結したものである。
図9は本発明の参考例2を示す。この参考例では、振動板2の一方の長辺側とフレーム1の対応する側とを一体構造とし、振動板2の一端部2aを薄肉にして屈曲自在、つまり振動板2を回動可能としたものである。
