Speaker with frequency directed dual drivers

摘要

A speaker that includes a pair of spaced-apart, in-plane mounted drivers connected in series to a network for applying the appropriate frequency component of the electrical input drive signal to each of the drivers is disclosed. A frequency dependent shunting network, such as a low pass filter, is applied to one of the drivers so as to gradually mute the one driver as a desired frequency is approached. The result is an aesthetically pleasing speaker that has dual in-plane drivers and that produces superior sound quality throughout the entire frequency range of the speaker, including those ranges in which dual, in plane, drivers tend to acoustically interfere with each other.

主权项

1. A speaker comprising:
a frame; a pair of drivers operably secured to said frame and spaced apart from each other by a defined distance; said pair of drivers connected in series; and a capacitor operably secured to one driver of said pair of drivers so as to gradually mute said one driver as a predefined frequency is approached and a capacitance of the capacitor to gradually mute said one driver at the predefined frequency is a function of the defined distance, wherein said capacitor also serves to gradually increase the power provided to the other driver as said predefined frequency is approached.
