Sound output device

1 . A sound output device, comprising:

at least two speaker units that include a diaphragm having a shape having a width direction and a length direction and output sound in a full-range frequency band; and

a sound control body including at least two sound guiding portions that are provided for respective speaker units of the at least two speaker units and through which sound output from the respective speaker units of the at least two speaker units passes, wherein

the at least two sound guiding portions have a first opening on a side of the at least two speaker units,

the first opening is provided as a sound input part,

the at least two sound guiding portions have a second opening on a side opposite to the sound input part,

the second opening is provided as a sound output part,

the sound output part is formed in a shape having a width direction and a length direction,

the sound output part has a width smaller than a width of the diaphragm,

the at least two sound guiding portions have a width that decreases from the sound input part toward the sound output part,

a cover panel that has a sound emission hole positioned corresponding to the sound output part and formed in a shape having the width direction and the length direction is provided,

at least a part of an outer surface of the cover panel is formed as an inclined surface that is displaced from a side of the sound input part to a side of the sound output part as approaching the sound emission hole in the width direction, and

a guard portion that covers both of the at least two sound guiding portions from the side of the sound output part and is positioned in the sound emission hole and through which sound having passed through the at least two sound guiding portions passes is provided.

2 . The sound output device according to claim 1 , wherein a control fin that controls sound from the sound input part toward the sound output part is provided inside the at least two sound guiding portions, the control fin has a rear end positioned slightly more in a front side than a rear end of the at least two the sound guiding portions is, and the control fin has a front end positioned slightly more in a front side than a front end of the at least two sound guiding portions is.

3 . The sound output device according to claim 2 , wherein the control fin is inclined with respect to a central axis of the diaphragm.

4 . The sound output device according to claim 1 , wherein the sound control body has a recessed space positioned on an outer peripheral side of the diaphragm in the width direction.

5 . The sound output device according to claim 1 , wherein an inner peripheral surface of the at least two sound guiding portions is formed in a shape in which two or more curved surfaces having different curvatures are continuous in a traveling direction of sound.

6 . The sound output device according to claim 1 , wherein at least a part of an inner peripheral surface of the at least two sound guiding portions is formed as an uneven surface in which a plurality of unevennesses is continuous.

7 . The sound output device according to claim 1 , wherein the sound control body has a first space and a second space that are positioned on an outer peripheral side of the diaphragm and are continuously formed, and the first space has a smaller volume and is positioned closer to the diaphragm than the second space.

8 . The sound output device according to claim 7 , wherein at least one of the first space or the second space is provided with a sound absorbing material.

9 . The sound output device according to claim 1 , wherein the sound control body has a sound conduit positioned on an outer peripheral side of the diaphragm.
