1. A speaker apparatus comprising:
- a phase inversion-type enclosure in which a speaker unit and a bass reflex port are installed, the bass reflex port having a tubular body whose hollow cross-sectional area gradually becomes smaller from a first opening side toward an inside of the bass reflex port in a first axial direction of the bass reflex port and gradually becomes larger from the inside of the bass reflex port toward a second opening side in the first axial direction, a length in a second direction being not changing and constant along the first axial direction of the bass reflex port, the second direction being one direction of the hollow cross section of the tubular body; and
a connecting space portion which connects the first opening side of the tubular body to an opening face of the enclosure,wherein the second direction is perpendicular to the opening face of the enclosure, andthe second direction is different from the first axial direction.

Abstract
A speaker apparatus according to the present invention includes a phase inversion-type enclosure in which a speaker unit and a bass reflex port are installed, the bass reflex port having a tubular body whose hollow cross-sectional area gradually becomes smaller from one opening side toward an inside of the bass reflex port in an axial direction of the bass reflex port, and a length in one direction of the hollow cross section of the tubular body not changing and constant along the axial direction.

4. A speaker apparatus comprising:
-
a phase inversion-type enclosure in which a speaker unit and a bass reflex port are installed, the bass reflex port having a tubular body whose hollow cross-sectional area gradually becomes smaller from a first opening side toward an inside of the bass reflex port in a first axial direction of the bass reflex port, a length in a second direction being not changing and constant along the first axial direction of the bass reflex port, the second direction being one direction of the hollow cross section of the tubular body; and a connecting space portion which connects the first opening side of the tubular body to an opening face of the enclosure, wherein the second direction is perpendicular to the opening face of the enclosure, the second direction is different from the first axial direction, a predetermined length portion of the tubular body portion along the first axial direction of the bass reflex port at a location at which the hollow cross-sectional area is smallest is a main tubular portion in which the hollow cross-sectional area is constant, a portion of the tubular body portion that connects to at least one end of the main tubular portion and in which the hollow cross-sectional area gradually increases from a side that connects to the main tubular portion toward the first opening side of the tubular body is an air rectifier, and the tubular body has a shape in which the hollow cross-sectional area gradually increases from a location where the hollow cross-sectional area is smallest toward a second bass reflex port opening side in the first axial direction of the bass reflex port. - View Dependent Claims (5)
