Embodiment 1

[0237] First-generation GQX, such as Figure 3b . Attenuation-type high-impedance high-fidelity, composed of a devil transformer connected in series between the stone machine and the speaker.

[0238] The second generation of GQX. exist Figure 10 Medium, U8 for high resistance and high fidelity Figure 4b The high-impedance and high-fidelity push-pull power amplifier is composed of discrete components or thick film integrated circuits.

[0239] The third generation of GQX. exist Figure 10 Medium, U8 for high resistance and high fidelity Figure 5b The external R composite pair tube is composed of high resistance and high fidelity.

[0240] The fourth generation of GQX. exist Figure 10 Medium, U8 for high resistance and high fidelity Figure 6a or Figure 6b The high-resistance and high-fidelity tube containing R composite pair is composed of discrete components or thick film integrated circuits.

[0241] exist Figure 10 Among them, the one that uses a single m...

Embodiment 2

[0246] Figure 10 , is already a complete GQX. Here, it is just used as the main power amplifier stage, and then a high-fidelity power amplifier is used as the front stage, and the two power amplifiers are combined in series. Its connection method is: the audio signal is input to the pre-stage high-fidelity power amplifier, and the amplified audio output signal is not connected to the speaker; while the output to the post-stage GQX: through the full-frequency pre-circuit, the volume is adjusted, and the high-resistance and high-resistance Real circuit, high voltage transmission, sent to the devil transformer to drive the speaker to produce sound. Push GQX with a stone machine. Like the waters of the Yangtze River, the waves behind push forward the waves ahead. At this time, the tone is beautiful, fuller, more textured, and more realistic. This is yet another entirely new type of GQX.

Abstract

The invention discloses a series of high definition stereo which is characterized by comprising a full-frequency front-end circuit, a high resistance and high fidelity circuit and a devil transformer. The three parts of the high-definition stereo adopt a connecting mode that audio signals are input to the full-frequency front-end circuit, sent to the high resistance and high fidelity circuit through volume adjustment, and sent to the devil transformer through high-voltage transmission to push a loudspeaker to sound. Through the combination, the high-definition stereo has high voltage and super dynamic, and pursues high output impedence R, and the timbre of the high-definition stereo is clear, transparent, round, plump, sweet, real and rich in elasticity, and shows nature again as a mountain stream.

Description

technical field [0001] The invention relates to a sound system, especially a high-definition pronunciation device capable of restoring and reproducing natural sounds. Background technique [0002] Traditional audio systems are divided into two categories: tube amplifiers and tube speakers. Its tone is more transparent and clear. However, the treble is not high, the bass is not low, flat and lacking enthusiasm. Heat generation, bulky, fragile, bulky, low efficiency, high power consumption, and expensive, are no longer mainstream products in the market. The mainstream product is the stone machine, which is a transistor audio system characterized by high-fidelity circuits and no output transformer. Its high-fidelity circuit achieves small distortion, wide frequency response and low cost. However, its timbre: rough, sharp, harsh, hard, crowded, unclear, loud, and the sound seriously pollutes the environment. [0003] why? For a long time, people have been pursuing a beauti...
