Abstract
To provide a mount structure of an electromechanical acoustic transducer which enables making of an attempt to pursuit miniaturization while maintaining an acoustic characteristic. A cylindrical closed-end yokeis attached to a frame, which is attached to an interior surfaceof a housingby way of a wall portion, in a direction where a bottomof the yoke approaches the housing; hence, a sound channelis defined between the yokeand the wall portionwithout an increase in the thickness of the electromechanical acoustic transducer. A superior acoustic characteristic can hereby be acquired. Alternatively, the sound channelcan be assured even when the electromechanical acoustic transducer is miniaturized, and thus an attempt can be made to pursuit miniaturization while maintaining an acoustic characteristic.
