Abstract

An electronic apparatus and a method for providing a sound system of the electronic apparatus are provided herein. The electronic apparatus has a housing, a speaker and a bracket. The housing has a space and a channel, which is coupled to the space. The speaker is placed in the space. The bracket has a first end coupled to the channel and is movable relative to the housing. A sound mode of the electronic apparatus may be switched from a first mode to a second mode by positioning a second end of the bracket from a first position in the channel to a second position away from the channel.

Claims

1. An electronic apparatus, comprising:

a housing, having a space and a channel, wherein the space and the channel coupled to each other;

a speaker, disposed in the space; and

a bracket, comprising a first end coupled to the channel, wherein the bracket is movable relative to the housing.

2. The electronic apparatus according to claim 1, wherein the bracket is placed in the channel.

3. The electronic apparatus according to claim 2, wherein a sound pressure level of an acoustic middle range sound from the electronic apparatus with the bracket is increased comparing with a sound pressure level of the acoustic middle range sound from an electronic apparatus without the bracket.

4. The electronic apparatus according to claim 1, wherein a gap is formed between the bracket and the channel when the bracket is placed in the channel.

5. The electronic apparatus according to claim 4, wherein a resonant frequency of a middle range boost of the electronic apparatus depends on the volume of the gap.

6. The electronic apparatus according to claim 4, wherein an inner chamber is formed between the bracket and the speaker when the bracket is placed in the channel.

7. The electronic apparatus according to claim 6, wherein a resonant frequency of a middle range boost of the electronic apparatus is represented by f₀,

8. The electronic apparatus according to claim 1 further comprising a hinge coupling the bracket to the channel.

9. The electronic apparatus according to claim 1 further comprising a spring coupling the bracket to the channel.

10. The electronic apparatus according to claim 1, wherein the length of the channel is more than twice as much as the length of the space.

11. The electronic apparatus according to claim 1, wherein the channel is placed along a midline of the housing.

12. The electronic apparatus according to claim 1, wherein the channel is placed at one end of the housing.

13. The electronic apparatus according to claim 1, further comprising a touch screen to be used as an interface for operating the electronic apparatus.

14. The electronic apparatus according to claim 1, wherein the bracket further comprises a second end which is movable between a first position in the channel and a second position away from the channel.

15. The electronic apparatus according to claim 14, wherein the second end which is moved away from the channel and forming an angle between the bracket and housing, the relationship between the angle and distance between a user is represented by

16. The electronic apparatus according to claim 14, wherein a sound pressure level of an acoustic bass range sound from electronic apparatus with the second end of the bracket moved to the second position is increased comparing with a sound pressure level of the acoustic bass range sound from an electronic apparatus without the bracket.

17. A method for providing a sound system of an electronic apparatus, comprising:

positioning a speaker of the electronic apparatus in a space of a housing of the electronic apparatus; and

coupling a bracket to a channel of the housing, wherein the space and the channel are coupled with each other,

wherein the bracket is movable relative to the housing.

18. The method according to claim 17, wherein the bracket comprises a first end which is coupled to the channel.

19. The method according to claim 17, wherein the bracket comprises a second end which is movable between a first position in the channel to a second position away from the channel.

20. The method according to claim 19, further comprising:

positioning the second end of the bracket from the first position in the channel to the second position away from the channel.

21. The method according to claim 20, wherein a sound pressure level of an acoustic bass range sound from the electronic apparatus with the second end of the bracket moved to the second position is increased comparing with a sound pressure level of the acoustic bass range sound from an electronic apparatus without the bracket.

22. The method according to claim 17, further comprising:

placing the bracket in the channel;

wherein a gap is formed between the bracket and the channel, and an inner chamber is formed between the bracket and the speaker.

23. The method according to claim 22, wherein a sound pressure level of an acoustic middle range sound from the electronic apparatus with the bracket is increased comparing with a sound pressure level of the acoustic middle range sound from an electronic apparatus without the bracket.

24. The method according to claim 17, wherein the length of the channel is more than twice as much as the length of the space.
