Abstract
A loudspeaker includes a first electro-acoustic transducer, a horn acoustically coupled to the first electro-acoustic transducer, and a first acoustic leak that is acoustically coupled to the horn. The first acoustic leak is positioned so as to reduce a peak in a frequency response of the loudspeaker at the targeted frequency without removing the targeted frequency from the output of the loudspeaker.
Claims19
A loudspeaker comprising:
- a first electro-acoustic transducer;
- a horn acoustically coupled to the first electro-acoustic transducer;
- and
- a first acoustic leak acoustically coupled to the horn,
- wherein the first acoustic leak is positioned so as to reduce a peak in a frequency response of the loudspeaker at a targeted frequency without removing the targeted frequency from the output of the loudspeaker, and
- wherein the first acoustic leak comprises a stub that defines an acoustic channel that has a length that is ¼ the wavelength (λ) of the target frequency, the ¼ λ stub further being in the form of a tube that circumferentially surrounds the horn.
