Abstract
An electric-acoustic transducer/housing assembly includes an electric-acoustic transducer and a housing within which the electric-acoustic transducer is arranged. The electric-acoustic transducer includes a casing, a first and second vibratory plates transversely mounted within the casing, and an exciter disposed between the first and second vibratory plates and operated to vibrate the first and second vibratory plates. The first vibratory plate cooperates with the exciter to define a first inner chamber therebetween. A sound pipe extends outwardly from the casing and is adapted to allow the first inner chamber to be communicated with the outside of the housing. The second vibratory plate cooperates with the exciter to define a second inner chamber therebetween. The casing has a through sound hole through which the second inner chamber is communicated with the outside of the casing. The sound pipe is kept out of communication with the through sound hole.
