Embodiment Construction

[0016] As can be seen from the foregoing, the Bel Canto circuit of the present invention has four notable features: one is high output impedance (usually greater than 24Ω); the other is a high voltage, low current, ultra-dynamic working environment; The output transformer is used for phase isolation; the fourth is that the output transformer adopts a multi-frequency transformer instead of a traditional audio transformer.

[0017] The bel canto circuit mentioned in this patent refers to a kind of unstaged output circuit that drives the loudspeaker to produce sound. What it pursues is beautiful sound output, making it more suitable for people's listening habits, so that people can enjoy beautiful music. However, it is difficult to use a certain amount as a criterion for judging the beauty of the sound. Since various electrical parameters of the Bel Canto circuit directly affect the quality of the sound, various electrical parameters of the circuit can be used to evaluate the so...

Abstract

The voice quality in the existed audio system cannot reach an ideal situation. In order to solve this problem, this invention adopts an audio power amplifier with an output impedance greater than 24 ohms. This power amplifier works under the hi-voltage and low-current situation to raise the quality of the voice output by the speaker. Connecting between the power amplifier and the speaker, the output transformer is an abnormal multi-frequency transformer. The voice output by this power amplifier possesses very beautiful hearing sense, rich tone color, strong expressive force, wide tessitura and high transparency. The tiny voices from various music instruments can clearly be distinguished.

Description

technical field [0001] The invention relates to an audio device, more specifically, to a method for improving the output sound quality of an audio system and an audio system using the method. Background technique [0002] For a long time, in pursuit of beautiful sound effects, there has always been a dispute between tube amplifiers and stone amplifiers among audio enthusiasts. Among them, tube amplifiers use electron tubes as the main working device, and their working voltage range is large, from a few volts to hundreds of volts or even thousands of volts, but the working current is very small, from a few milliamperes to tens of milliamperes, which belongs to high voltage and low current. The working amplifier can output stretchy, elastic and full-bodied sound effects, with a feeling of fullness and harmony. In contrast, the stone machine uses transistors as the main working device, which is an amplifier with high current and low voltage. Its output sound is crisp and pleas...
