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.

1. A mobile phone, comprising: a housing, having a space and a channel, wherein the space and the channel are coupled to each other;a stand, comprising a first end and a second end, wherein the first end is coupled to the channel, and the stand is moved relatively to the housing; anda speaker, dispo
1. A mobile phone, comprising: a housing, having a space and a channel, wherein the space and the channel are coupled to each other;a stand, comprising a first end and a second end, wherein the first end is coupled to the channel, and the stand is moved relatively to the housing; anda speaker, disposed in the space, facing toward the stand and configured to generate a sound wave toward the stand,wherein when the second end is disposed inside the channel, an inner chamber is formed between the stand and the speaker to resonate with the sound wave, and when the second end is disposed outside of the channel, the second end of the stand supports the electronic device via the first end, and the sound wave is transmitted out of the electronic mobile phone via the channel,wherein a gap is formed between the stand and the channel when the stand is disposed inside the channel, and a resonant frequency of a middle range boost of the mobile phone depends on a volume of the gap, a width and a length of the stand and a volume of the inner chamber, wherein the volume of the gap determines an equivalent inductance value between the stand and the housing, and the volume of the inner chamber determines an equivalent capacitance value of the inner chamber,wherein the channel and the space are respectively placed at a first region and a second region of a side of the housing which faces to the stand, and when the stand is disposed inside the channel, the gap is formed and placed at the first region, the inner chamber is formed and placed at the second region, wherein the gap has a first distance from the channel to the stand, the inner chamber has a second distance from the speaker to the stand, and the second distance is greater than the first distance. 2. The mobile phone according to claim 1, wherein a sound pressure level of an acoustic middle range sound from the mobile phone with the stand is increased comparing with a sound pressure level of the acoustic middle range sound from a mobile phone without the stand. 3. The mobile phone according to claim 1, wherein a resonant frequency of a middle range boost of the mobile phone is represented by f0, f0=12π1LC,L is an inductance value equal to 1.21×LKWK×D, C is a capacitance value equal to V1.21×343, D is a numerical portion of the volume of the gap, WK is a numerical portion of the width of the stand, LK is a numerical portion of the length of the stand, V is a numerical portion of the volume of the inner chamber. 4. The mobile phone according to claim 1 further comprising a hinge coupling the stand to the channel. 5. The mobile phone according to claim 1 further comprising a spring coupling the stand to the channel. 6. The mobile phone according to claim 1, wherein the length of the channel is more than twice as much as the length of the space. 7. The mobile phone according to claim 1, wherein the channel is placed along a midline of the housing. 8. The mobile phone according to claim 1, wherein the channel is placed at one end of the housing. 9. The mobile phone according to claim 1, further comprising a touch screen to be used as an interface for operating the mobile phone. 10. The mobile phone according to claim 1, wherein the second end which is moved away from the channel and forming an angle between the stand and housing, the relationship between the angle and distance between a user is represented by s2=r2+t2-2×r×t×cosφ,andφ=π2+θ, where r is a distance from the speaker to a top of the housing, s is a distance from the top to the ear of the user, t is a distance from the speaker to the ear of the user, φ is an included angle between the stand and a sound path from the speaker to the ear of the user, and θ is an included angle between the stand and the housing. 11. The mobile phone according to claim 1, wherein a sound pressure level of an acoustic bass range sound from the mobile phone with the second end of the stand moved to the second position is increased comparing with a sound pressure level of the acoustic bass range sound from a electronic apparatus mobile phone without the stand. 12. A method for providing a sound system of a mobile phone, comprising: positioning a speaker of the mobile phone in a space of a housing of the mobile phone;coupling a first end of a stand to a channel of the housing, wherein the space and the channel are coupled with each other; andmoving the stand in the channel,wherein the stand is moved relatively to the housing and comprises the first end and a second, the speaker faces toward the stand and is configured to generate a sound wave toward the stand, when the second end is disposed inside the channel, an inner chamber is formed between the stand and the speaker to resonate with the sound wave, and when the second end is disposed outside of the channel, the second end of the stand supports the electronic device via the first end, and the sound wave is transmitted out of the mobile phone via the channel,wherein a gap is formed between the stand and the channel when the stand is disposed inside the channel, and a resonant frequency of a middle range boost of the mobile phone depends on a volume of the gap, a width and a length of the stand and a volume of the inner chamber, wherein the volume of the gap determines an equivalent inductance value between the stand and the housing, and the volume of the inner chamber determines an equivalent capacitance value of the inner chamber,wherein the channel and the space are respectively placed at a first region and a second region of a side of the housing which faces to the stand, and when the stand is disposed inside the channel, the gap is formed and placed at the first region, the inner chamber is formed and placed at the second region, wherein the gap has a first distance from the channel to the stand, the inner chamber has a second distance from the speaker to the stand, and the second distance is greater than the first distance. 13. The method according to claim 12, further comprising: positioning the second end of the stand from the first position in the channel to the second position away from the channel. 14. The method according to claim 13, wherein a sound pressure level of an acoustic bass range sound from the mobile phone with the second end of the stand moved to the second position is increased comparing with a sound pressure level of the acoustic bass range sound from an mobile phone without the stand. 15. The method according to claim 12, wherein a sound pressure level of an acoustic middle range sound from the mobile phone with the stand is increased comparing with a sound pressure level of the acoustic middle range sound from an mobile phone without the stand. 16.
