In addition to the improvement of visual effects, the progress in sound effects has not been compromised. At present, personal computers that emphasize audiovisual effects have constructed a 5. 彳 channel sound effect device with a view to Provide users with more professional hearing enjoyment. Although the performance of existing personal TVs in s-effects has greatly surpassed the past, for professional audio players, the current computer audio equipment is still insufficient. Same as general digital audio equipment, most of the sound effects equipment on personal computers currently use transistor amplifiers. For audio players with higher sound quality requirements, t, t crystal amplifiers are human speaking. It is sharp, cold and hard, with artificial flavor. The reason is that odd harmonic distortion occurs when the transistor is working. This distortion is repelled by the human ear. The audio players all know that the top professional audio systems use vacuum tube amplifiers, and the vacuum tube has distortion when it works. {A kind of even harmonics are out of alignment ^ Is fun I: Human ears do not exclude this distortion, Instead, there is a warm and thick hearing experience; in other words, the transistor has completely replaced the vacuum tube in terms of music reproduction. The vacuum tube amplifier is still the favorite of audio players. For this reason, computer manufacturers are not behind attempts to integrate the vacuum tube expansion 3 M276248 mainframe to the mainframe for the pre-amplification of analog sound sources. For example, the Chinese Patent Publication No. CN 1469234A "The computer system with sound amplifier circuit built in the motherboard" invention patent case. According to the content of the publication, it can be understood that the disclosed invention patent case is a direct effect amplifier circuit composed of a vacuum tube. Set on the computer motherboard, as a preamplifier for analog sound sources. The biggest problem with this method is that the layout design of the motherboard must be changed. But this change can be described as significant, not only the high implementation cost, the relatively high obstacles to implementation, but also the disadvantages of large volume and weight, and difficult maintenance. [New content] As can be seen from the above, the vacuum tube amplifier is used as a preamplifier for computer analog sound sources to provide a professional sound quality performance. Although it is a feasible direction, consider the feasibility of implementation and other aspects such as assembly and maintenance. other problems. Therefore, the main purpose of this creation is to mention it on the mainframe of the computer. "It is important to install the effect device in the form of peripherals; because it is based on the week, it is convenient, convenient, and easy to inspect." The main technical means known for the purpose is to make the aforementioned sound effect installation box, its appearance form the specifications of the human slot; ', σ computer host peripheral equipment expansion a β amplifier' is located in the aforementioned eight with a sound source M276248 • input bee, To receive the main drag, main h 'port; k analog audio source; also has a sound source output * the aforementioned sound effects device you recognize ^^, Φ ^ a receiver is equipped with a vacuum tube amplifier, so it can be relocated and received by the host Shiyoutu's cheek-to-sound source is preamplified so that the output sound source of the host computer is Ding Yue j, and double eight, one has a professional sound quality performance. Also, because the Lü Hai sound effect device is installed in the peripheral expansion slot of the host in a peripheral and ready form, it is not only convenient for donkeys ^ ^ 66 ® ^ ^-,,,, and quasi-t, and there is no need to change the computer host The original 5 and 10 of the board, the basin will you; /, low yoke cost, and small obstacles to implementation.
