TWM326753U - Digital audio signal amplifier - Google Patents

Abstract

A digital audio signal amplifier includes: a digital signal amplifying module having a digital audio signal plug connected with a digital audio signal outlet of a mainboard to receive digital audio signals, and the digital signal amplifying module processing the digital audio signals to generate high power analog audio signals; and an analog signal output interface coupled to the digital signal amplifying module and transferring the high power analog audio signals to a set of speaker.

Description

M326753 VIII. New Description: [New Technology Field] This is a kind of audio amplifier, especially a digital audio amplifier that supplies amplifier high-power analog audio signals. [Prior Art], the advancement of personal computer functions and the development of the Internet have made the personal computer more and more powerful, whether it is online games or online playback of multimedia audio and video effects. However, the built-in speakers of the computer are too simple. The quality of the sounds is very poor. This is a great discount for the online game or multimedia entertainment. All the sound files on the computer are digital, like MjDI. WAVE, Mp3, etc. or music CDs, VCDs, DTOs, and other movie discs are digital, but our traditional analogy analogy, when converting digital signals into analog signals, the signal will be attenuated and will be affected by the computer chassis. The noise of the circuit noise and the noise, so the sound is poor, and even the conversion of the money will produce noise and miscellaneous sfL, so that the sound is not clear and clean, and you may hear the sound of "sand" when you listen carefully. Recently, computer systems have been developed to support universal serial (USB) interfaces, especially for small computer systems, because it allows the computer system to work with a variety of USB peripherals without adding more Connector. I know a USB digital speaker, which is connected to the computer USB port. It does not need to be converted in a very serious interference chassis, and directly enjoy high-quality digital sound, which will of course make your computer play more sound. Clear and no noise, it sounds more realistic and transparent, and it feels very different from listening to analog speakers. However, due to the power relationship, an additional power cord must be added to provide a good sound effect. Therefore, it is inconvenient for the speaker to be used, and generally the high quality La 9 is separated from the amplifier component to avoid the rational sound wave of the crop. Interference is caused during operation. In this way, the above-mentioned π 八 is not able to achieve the best performance.
