The notebook is connected to the amplifier for improved sound.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an expansion base, especially an expansion base for improved sound and heat dispersion.
2. Description of the Prior Arts
Standard notebooks are too small for additional heat sinks to be implemented so the notebooks are only cooled by thermal convection from a cover of the notebook to outside air. Besides, the standard notebook has small speakers to save weight so sound quality is low. Therefore, when the people use the notebook, heat generated by the notebook accumulates inside the notebook reducing performance and may even damage the notebook.
To overcome the shortcomings, the present invention provides an expansion base to mitigate or obviate the aforementioned problems.
SUMMARY OF THE INVENTION
The main objective of the present invention is to provide an expansion base, especially to an expansion base for improved sound and heat dispersion.
An expansion base in accordance with the present invention has a body and an amplifier. The body has a front, an outer surface, a container, multiple through holes and a protruding strip. The through holes are formed through the outer surface of the body. The protruding strip is formed transversely on and protrudes from the outer surface at the front of the body. The amplifier is mounted in the container of the body and has at least one woofer and two speakers. The at least one woofer is mounted in the container adjacent to the through holes of the body. Each tweeter is mounted in the container.
When the notebook is placed on the protruding strip a space is formed between a surface and the notebook for improved user-comfort and heat dissipation. The notebook is connected to the amplifier for improved sound.
Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

The container (11) is formed transversely through the body (10) and has two ends, two openings (12) and two sleeves (13).
The openings (12) are formed respectively in the ends of the container (11).
The sleeves (13) are mounted respectively on the openings (12) of the container (11) and each sleeve (13) has an inner surface and a dust-proof cover (14). The dust-proof cover (14) is mounted on the inner surface of the sleeve (14) to seal the container (11) from dust.
The through holes (15) are formed through the outer surface of the body (10) and may have various sizes for improved acoustic or aesthetic effects. Preferably, the through holes (15) are formed longitudinally in lines from end to end of the container and a central line is formed from larger through holes (15) with adjacent lines gradually decreasing.
The protruding strip (16) is formed transversely on and protrudes from the outer surface at the front of the body (10) and may be mounted on a notebook or a DVD player.
The skid-proof strips (17, 18) are mounted transversely on the protruding strip (16) and on the body (10) to prevent movement of the body (10) relative to a notebook and a surface.
The mounting hole (19) is formed in the outer surface at the back of the body (10).
The amplifier (20) is mounted in the container (11) of the body (10) and has a seat (23), a cover (24), at least one woofer (21) and two speakers (22).
The seat (23) has a top surface, a first end, a second end, a first ring wall (25) and a third ring wall (26). The first ring wall (25) is formed on the top surface of the seat (23) and has a first sound wall (251). The first sound wall (251) is formed in the first ring wall (25) of the seat (23). The third ring wall (26) is formed on the top surface and is adjacent to the second end of the seat (23).
The cover (24) is mounted on the seat (23) and has a first hole, a second ring wall (27), a second hole and a fourth ring wall (28).
The first hole is formed on the cover (24) and corresponds to the first ring wall (25) of the seat and has a rim. The second ring wall (27) is formed on the rim of the first hole and is mounted between the first ring wall (25) and the first sound wall (251) and has top edge and a second sound wall (271). The second sound wall (271) is formed on the top edge of the second ring wall (27) and mounted in the first sound wall (251) of the seat (23).
The second hole is formed on the cover (24) and corresponds to the third ring wall (26) of the seat and has a rim. The fourth ring wall (28) is formed on the cover (24) and is mounted in the third ring wall (26) of the seat (23).
The at least one woofer (21) is mounted in the container (11) adjacent to the through holes (15) of the body (10). In the performed embodiment, the at least one woofer (21) is mounted on the first end of the seat (23) and is covered the cover (24).
The speakers (22) are mounted in the container (11) and may be mounted in the sleeves (13). In the performed embodiment, The speakers (22) are mounted on the seat (23) adjacent to the second end of the seat (23).
The controller (30) is mounted in the mounting hole (19) of the body (10) and is connected to the amplifier (20) to control characteristics of the amplifier (20) such as bass, treble, volume and the like and has at least one actuator and at least one jack adapted to connect to the notebook or the DVD player and a power source. The at least one actuator may be a power switch, a volume control, a bass control a treble control or the like. The at least one jack may be a USB port, a headphone jack, a power socket or the like. The power source may be the notebook.
The expansion base can be used for a notebook or a DVD player. With further reference to FIG. 5, the expansion base for notebooks (40) is placed on a surface, such as a table, desk, chair or the like and the notebook is placed on the protruding strip (16). Therefore, the notebook (14) is not mounted flatly on the surface for improved writing comfort for a user. Furthermore, a space is formed between the notebook surface so heat can be dispersed to the environment to prevent heat damage to the notebook. Besides, the notebook (40) can be connected to amplifier (20) by the controller (30) for improved sound.
