Description
前記ドライバーユニットが前記ドラム内空間と連通する内部音導口を備えることが好ましい。
前記リアヘッドに孔を設けることが好ましい。
ドラムエアパワーシステムの実施形態であるインナーイヤー型ヘッドフォン1(以下、イヤフォン1とする)は、太鼓形状のケーシング2と、ケーシング2の前後方向の前部に設けるフロントヘッド3と、ケーシング2の前後方向の後部に設けるリアヘッド4と、ケーシング2、フロントヘッド3およびリアヘッド4により画定されるドラム内空間5aと、を有するドラム5を備えている。ドラム5内に外部音導部6aと内部音導口6bを有するドライバーユニット6が備えられている。ドライバーユニット6を駆動させ内部音導口6bからドラム内空間5aに音を出すことでフロントヘッド3とリアヘッド4を共振させる。リアヘッド4に孔7を設けることで前記共振による低音を制御する。このようなドラムエアーパワーを利用した方式をDAP方式と呼ぶ。以下詳細に説明する。
2・・・ケーシング
2a・・・円環状突出部
2b・・・円環状突出部
3・・・フロントヘッド
4・・・リアヘッド
5・・・ドラム
5a・・・ドラム内空間
6・・・ドライバーユニット
6a・・・外部音導部
6b・・・内部音導口
7・・・孔
8・・・後部外殻
8a・・・後部空間
9・・・孔
