Abstract

A sound outputting apparatus is provided. The sound outputting apparatus includes: a main body; and a loudspeaker accommodated in the main body. The loudspeaker includes: a vibration member configured to generate sound waves; and a sound guide having a first end connected to the vibration member, a second end having an open structure, a first surface between the first end and the second end, and a plurality of openings formed through the first surface along a longitudinal direction of the sound guide. The plurality of openings increase in size as distance from the vibration member increases.

First claim

What is claimed is:

1. A loudspeaker comprising:
a vibration member configured to generate sound waves; and
a sound guide having a first end connected to the vibration member, a second end having an open structure, a first surface between the first end and the second end, and a plurality of openings formed through the first surface along a longitudinal direction of the sound guide,
wherein the plurality of openings increase in size as distance from the vibration member increases,
wherein the sound guide has a second surface, opposite the first surface, between the first end and the second end,
wherein the first surface is planar, and
wherein distance between the first surface and the second surface increases as distance from the vibration member increases along the longitudinal direction.

2. The loudspeaker as claimed in claim 1 , wherein a cross-section of the sound guide has one from among a circular shape, an elliptical shape and a polygonal shape.

3. The loudspeaker as claimed in claim 1 , wherein a cross-sectional area of the sound guide increases as distance from the vibration member increases along the longitudinal direction.

4. The loudspeaker as claimed in claim 1 , wherein size of the plurality of openings increases based on a non-linear ratio as distance from the vibration member increases along the longitudinal direction.

5. The loudspeaker as claimed in claim 1 , wherein the plurality of openings comprise:
a plurality of first openings that increase in size based on a predetermined ratio as distance from the vibration member increases along the longitudinal direction; and
a plurality of second openings arranged subsequently to the plurality of first openings and a size corresponding to one of the plurality of first openings.

6. The loudspeaker as claimed in claim 1 , wherein the plurality of openings are arranged in each of a plurality of rows along the longitudinal direction.

7. The loudspeaker as claimed in claim 1 , wherein the plurality of openings each have one from among a circular shape, an elliptical shape, a rectangular shape, a square shape and a rhombus shape.

8. The loudspeaker as claimed in claim 1 , wherein the plurality of openings are spaced apart from each other by a predetermined interval.

9. The loudspeaker as claimed in claim 1 , wherein an interval between the plurality of openings decreases as distance from the vibration member increases.

10. A sound outputting apparatus comprising:
a main body; and
a loudspeaker accommodated in the main body,
wherein the loudspeaker comprises:
a vibration member configured to generate sound waves; and
a sound guide having a first end connected to the vibration member, a second end having an open structure, a first surface between the first end and the second end, and a plurality of openings formed through the first surface along a longitudinal direction of the sound guide,

wherein the plurality of openings increase in size as distance from the vibration member increases,
wherein the sound guide has a second surface, opposite the first surface, between the first end and the second end,
wherein the first surface is planar, and
wherein distance between the first surface and the second surface increases as distance from the vibration member increases along the longitudinal direction.

11. The sound outputting apparatus as claimed in claim 10 , wherein a cross-section of the sound guide has one from among a circular shape, an elliptical shape and a polygonal shape.

12. The sound outputting apparatus as claimed in claim 10 , wherein a cross-sectional area of the sound guide increases as distance from the vibration member increases along the longitudinal direction.

13. The sound outputting apparatus as claimed in claim 10 , wherein size of the plurality of openings increases based on a non-linear ratio as distance from the vibration member increases along the longitudinal direction.

14. The sound outputting apparatus as claimed in claim 10 , wherein the plurality of openings comprise:
a plurality of first openings that increase in size based on a predetermined ratio as distance from the vibration member increases along the longitudinal direction; and
a plurality of second openings arranged subsequently to the plurality of first openings and a size corresponding to one of the plurality of first openings.

15. The sound outputting apparatus as claimed in claim 10 , wherein the plurality of openings are arranged in each of a plurality of rows along the longitudinal direction.

16. The sound outputting apparatus as claimed in claim 10 , wherein the plurality of openings each have one from among a circular shape, an elliptical shape, a rectangular shape, a square shape and a rhombus shape.

17. The sound outputting apparatus as claimed in claim 10 , wherein the plurality of openings are spaced apart from each other by a predetermined interval.

18. The sound outputting apparatus as claimed in claim 10 , wherein an interval between the plurality of openings decreases as distance from the vibration member increases.

19. The sound outputting apparatus as claimed in claim 10 , wherein the main body has a bar shape, and
wherein the loudspeaker is accommodated in a first end of the main body and another loudspeaker is accommodated in a second end of the main body.

20. A loudspeaker comprising:
a vibration member configured to generate sound waves; and
a sound guide having a first end connected to the vibration member, a second end having an open structure, a first surface between the first end and the second end, and a first opening formed through the first surface along a longitudinal direction of the sound guide,
wherein a width of the first opening increases as distance from the vibration member increases,
wherein the sound guide has a second surface, opposite the first surface, between the first end and the second end,
wherein the first surface is planar, and
wherein distance between the first surface and the second surface increases as distance from the vibration member increases along the longitudinal direction.

21. A loudspeaker comprising:
a sound guide having a first end, a second end having an open structure, a first surface between the first end and the second end, and a plurality of openings formed through the first surface along a longitudinal direction of the sound guide,
wherein the plurality of openings increase in size as distance from the first end increases,
wherein the sound guide has a second surface, opposite the first surface, between the first end and the second end,
wherein the first surface is planar, and
wherein distance between the first surface and the second surface increases as distance from the vibration member increases along the longitudinal direction.
