Abstract
A sound field equalizing apparatus for a speaker system which is capable of widening a region in which it is possible to effectively hear a sound field. The apparatus includes a sound field equalizing member disposed in a dispersing hole formed in a cabinet of a speaker for separating a sound dispersed from the speaker into a forwardly dispersed sound which is dispersed in a central direction and a laterally dispersing sound which is dispersed in a peripheral direction of the forwardly dispersing sound.
Claims20
An apparatus for a speaker system, comprising:
- a housing for storing a speaker therein, the housing including a cabinet having a front panel, and a dispersing hole formed in the front panel of the cabinet;
- and
- a sound horn disposed in the dispersing hole such that no other sound horn encloses the sound horn, wherein an inlet diameter of the sound horn is less than a diameter of a diaphragm of the speaker and wherein sounds from the diaphragm travel within an interior surface and also to an exterior surface of the sound horn,
- and wherein said sound horn defines a forwardly dispersing sound path through the sound horn;
- and
- wherein a laterally dispersing sound path is defined between an outer circumferential surface of the sound horn and an inner circumferential surface of said dispersing hole formed in said front panel of the cabinet, whereby sound exits said speaker housing both from said sound horn along said forward dispersing sound path and along said laterally dispersing sound path through said dispersing hole.

An apparatus for a speaker system, comprising:
- a housing for storing a speaker therein, the housing including a panel portion and a dispersing hole formed in said panel portion;
- and
- a sound horn disposed in said dispersing hole such that no other sound horn encloses the sound horn and sounds from a diaphragm of said speaker travel within an interior surface and also to an exterior surface of the sound horn, and an inlet diameter of said sound horn being less than a diameter of the diaphragm of the speaker,
- and wherein said sound horn defines a forwardly dispersing sound path through the sound horn;
- and
- wherein a laterally dispersing sound path is defined between an outer circumferential surface of the sound horn and an inner circumferential surface of said dispersing hole formed in said panel portion, whereby sound exits said speaker housing both from said sound horn along said forward dispersing sound path and along said laterally dispersing sound path through said dispersing hole in said panel portion.
