Abstract

An electronic apparatus may include a loudspeaker that includes an enclosure; a first driver disposed in the enclosure and configured to output a sound based on an input audio signal; a unit accommodator having a hole in which the first driver is disposed, and extending toward an inside of the enclosure; a space forming portion extended from an outer edge of the unit accommodator, surrounding a back of the first driver to form a space with the unit accommodator, and spaced apart from an inner edge of the unit accommodator; a slot forming portion extending from the space forming portion, and having an inner surface spaced apart from an outer surface of the unit accommodator to form a first sound output passage; and a sound absorber disposed at at least one of the outer surface of the unit accommodator and the inner surface of the slot forming portion.

First claim

What is claimed is:

1. An electronic apparatus comprising:
a loudspeaker comprising:
an enclosure;
a first driver disposed in the enclosure and configured to output a sound based on an input audio signal;
a unit accommodator having a hole in which the first driver is disposed, and extending toward an inside of the enclosure;
a space forming portion extended from an outer edge of the unit accommodator, surrounding a back of the first driver to form a space with the unit accommodator, and spaced apart from an inner edge of the unit accommodator, wherein the sound provided in the back of the first driver travels through the space formed between the space forming portion and the inner edge of the unit accommodator;
a slot forming portion extending from the space forming portion, and having an inner surface spaced apart from an outer surface of the unit accommodator to form a first sound output passage; and
a sound absorber disposed at at least one of the outer surface of the unit accommodator or the inner surface of the slot forming portion and disposed in between the first driver and the inner edge of the unit accommodator to absorb the sound traveled through the space forming portion.

2. The electronic apparatus according to claim 1 , wherein the first driver is configured to generate a back wave toward the space forming portion, the back wave traveling through the first sound output passage.

3. The electronic apparatus according to claim 1 , wherein the sound absorber seals the first sound output passage.

4. The electronic apparatus according to claim 1 , wherein the sound absorber comprises at least one of an uneven portion or a plurality of slits on the outer surface of the unit accommodator along the first sound output passage.

5. The electronic apparatus according to claim 1 , wherein the unit accommodator comprises at least one of a flat plate shape, a polygonal shape, or a rounded flat plate shape.

6. The electronic apparatus according to claim 1 , wherein the unit accommodator is curved with the first sound output passage.

7. The electronic apparatus according to claim 1 , wherein the enclosure further comprises a protrusion extending from the inner surface of the space forming portion, and
wherein the protrusion is a flat plate and has an end portion spaced apart from the inner edge of the unit accommodator.

8. The electronic apparatus according to claim 1 , wherein the enclosure further comprises a port forming a second sound output passage in an area of the space forming portion behind the first driver.

9. The electronic apparatus according to claim 1 , wherein the loudspeaker comprises a second driver provided adjacent to the first driver.

10. The electronic apparatus according to claim 9 , wherein the loudspeaker comprises a second space forming portion surrounding a back of the second driver.

11. The electronic apparatus according to claim 1 , further comprising a second driver,
wherein the unit accommodator further comprises:
a first unit accommodator provided with the first driver to face toward a first inner surface of a first slot forming portion forming the first sound output passage therebetween; and
a second unit accommodator comprising a second inner edge spaced apart from a first inner edge of the first unit accommodator, and provided with the second driver to face toward a second inner surface of a second slot forming portion,
wherein the second inner surface of the second slot forming portion forms a third sound output passage in an opposite direction to the first sound output passage.

12. The electronic apparatus according to claim 11 , wherein the electronic apparatus further comprises a display.

13. The electronic apparatus according to claim 1 , wherein the first driver is spaced apart at a predetermined distance from the outer edge of the unit accommodator.

14. The electronic apparatus according to claim 1 , further comprising a third driver provided in a second hole of the space forming portion.

15. The electronic apparatus according to claim 14 , further comprising a third space forming portion surrounding the back of the first driver, and a second port through which the third space forming portion is connected to the first sound output passage.

16. A loudspeaker comprising:
a driver configured to emit sound;
a unit accommodator comprising the driver and a back slot portion adjacent to the driver;
a space forming portion connected to an outer edge of the unit accommodator;
a slot forming portion connected to the space forming portion, wherein the slot forming portion is spaced apart from the unit accommodator and an inner surface of the slot forming portion faces a front side of the driver; and
a sound absorber disposed at at least one of an outer surface of the unit accommodator or the inner surface of the slot forming portion and disposed in between the driver and an inner edge of the unit accommodator to absorb the sound traveled through the space forming portion.
