ABSTRACT:
In the construction of an electric acoustic converter such as a speaker for musical instruments, a tone generating unit arranged near one open end of a resonant tube is accompanied with a partition which has a central through hole and extends across the longitudinal hole of the resonant tube. For complicated modes of resonance and rich acoustic vibration, two or more resonant tubes of different types may be used in combination with one or more tone generating units. Presence of such a partition clearly defines the length of the resonant air columns to be produced in the resonant tube and such clear-cut resonant air columns bring about high resonance sharpness.
