It is desirable to develop a sound effect processing system applied to computer, which allows a user to directly control it via a hardware interface to adjust sound signal frequencies and improve sound quality without the need of using any software or driver.
SUMMARY OF THE INVENTION
A primary object of the present invention is to develop a sound effect processing system, so that a user may use a hardware sound quality adjustment control unit to control a sound quality processing unit on a computer to process and modify the sound quality as a signal frequency characteristic of sounds input to or output from the computer.
To achieve the above and other objects, the sound effect processing system applied to computer according to the present invention includes a sound quality processing unit provided on a computer for processing and modifying sound quality as a signal frequency characteristic of sounds being input to or output from the computer, and a hardware sound quality adjustment control interface, via which a user may directly control the sound effect processing system to adjust sound signal frequencies and improve the sound quality without the need of using any software or driver.
In the present invention, the hardware sound quality adjustment control interface adjusts and controls the sound quality processing unit.

As shown, the sound effect processing system in the second embodiment, which is generally denoted a reference numeral 11, includes at least one output unit 12 for outputting sounds, such as a headphone; a sound quality processing unit 13, such as an equalizer or a firmware stored on a read-only memory (ROM), being in the form of a chip or a circuit provided on a sound effect card 15, which is internally connected to a computer 14, for processing and modifying the sound quality as a signal frequency characteristic of sounds before the sounds are output via the output unit 12; and a hardware sound quality adjustment control interface 16, such as at least one push key, a turning knob, or a slidable adjusting key, being provided on the computer 14 for adjusting and controlling the sound quality processing unit 13. The sound quality processing unit 13 processes and modifies not only the signal frequency characteristic of sounds output from the computer 14, but also the signal frequency characteristic of sounds input to the computer 14.
FIG. 3 is a systematic view of a sound effect processing system applied to computer according to a third preferred embodiment of the present invention. As shown, the sound effect processing system in the third embodiment, which is generally denoted a reference numeral 21, includes at least one output unit 22 for outputting sounds, such as a headphone; a sound quality processing unit 23, such as an equalizer or a firmware stored on a read-only memory (ROM), being in the form of a chip or a circuit provided on a sound effect card 25, which is internally connected to a computer 24, for processing and modifying the sound quality as a signal frequency characteristic of sounds before the sounds are output via the output unit 22; and a hardware sound quality adjustment control interface 26, such as a wireless remote controller, being provided on the computer 24 for adjusting and controlling the sound quality processing unit 23. The sound quality processing unit 23 processes and modifies not only the signal frequency characteristic of sounds output from the computer 24, but also the signal frequency characteristic of sounds input to the computer 24.
FIG. 4 is a systematic view of a sound effect processing system applied to computer according to a fourth preferred embodiment of the present invention. As shown, the sound effect processing system in the fourth embodiment, which is generally denoted a reference numeral 31, includes at least one output unit 32 for outputting sounds, such as a headphone; a sound quality processing unit (not shown) being in the form of a chip or a circuit provided on a sound effect card 35, which is externally connected to a computer 34, for processing and modifying the sound quality as a signal frequency characteristic of sounds before the sounds are output via the output unit 32; and a hardware sound quality adjustment control interface 36, such as at least one push key, a turning knob, or a slidable adjusting key, being provided on the sound effect card 35 for adjusting and controlling the sound quality processing unit.
