の間の磁気的相互作用により、前記電磁石と空隙を介し
て対向させた前記振動板を振動させる音響変換部を、前
記電磁石のヨークが底部を形成するようにしてケース内
に収納し、前記ケース内の前記振動板の前面及び背面に
空洞共振系を形成した音響変換器において、前記ケース
に、前記音響変換部を収納する空室から区画された別の
空室を設け、該空室を、前記電磁石を構成するヨ、−り
に設けた切欠を通して、前記振動板の背面側の空洞共振
系と連通させたことを特徴とする音響変換器。The yoke of the electromagnet forms an acoustic transducer that vibrates the diaphragm facing the electromagnet with an air gap interposed therebetween due to magnetic interaction between the electromagnet and a permanent magnet arranged to surround the electromagnet. In the acoustic transducer, the acoustic transducer is housed in a case to form a cavity, and a cavity resonance system is formed on the front and back surfaces of the diaphragm in the case, wherein the case is partitioned from a cavity in which the acoustic transducer is housed. an acoustic transducer characterized in that a separate cavity is provided, and the cavity is communicated with a cavity resonant system on the back side of the diaphragm through a notch provided on the side and the rim of the electromagnet. vessel.
