Embodiment Construction

[0015] Please refer to figure 1 , figure 1 is a schematic diagram of the computer system 8 of the present invention. The computer system 8 includes a processor 9 , a motherboard 10 , an audio amplification circuit 11 , a motherboard built-in audio chip 13 , a first switch 15 , an expansion slot sound card 17 and a frequency isolation wall 12 . The built-in audio chip 13 of the motherboard is electrically connected to the audio amplifier circuit 11, and the connection between the two is determined by the first switch 15. When the motherboard 10 is turned on, it will automatically detect the adjustment status of the jumper in the first switch 15 to determine whether the sound effect generated by the built-in sound chip 13 of the motherboard should be amplified by the audio amplifier circuit 11. In addition, the motherboard The sound effect generated by the built-in sound effect chip 13 will be directly output from the sound source output hole 21 built in the motherboard. The ...

Abstract

The present invention provides one kind of computer system including one mainboard, one audio amplifier set on the mainboard and one processor to control the operation of the computer. The audio amplifier circuit includes one class-A current amplifier, one filament heater circuit and one voltage raising regulator circuit. The class-A current amplifier has one vacuum tube, so that the computer system has the function of one professional preamplifier.

Description

technical field [0001] The invention provides a computer system, especially a computer system in which a sound effect amplifier circuit is built on a motherboard. Background technique [0002] In the current computer world, personal computers can be said to be more and more common. Moreover, the functions are becoming more and more powerful, and the functions that a computer can handle have exceeded our imagination. Therefore, it can be said that all the functions of home appliances are realized on a personal computer, which can be said to be the direction that various information companies are striving for now. But in the personal computer of the past, it was an impossible dream. [0003] For example, in the era of the earliest x86 personal computer, the 8088 XT launched by IBM, personal computer users could only output a single-frequency sound through a simple PC speaker, or into a user, a sound card would be installed. , but still can only hear...
