[0004]However, the inventor found in the further research and development of high-definition audio: on the one hand, the circuit with larger output resistance has lower ability to drive the load and higher output power Small
On the other hand, the higher the impedance of the devil transformer, the greater its inductance and the greater the high frequency loss

The invention discloses a high-definition circuit for a high-definition speaker, which is characterized in that a common-base circuit, or a plurality of series connected common-base circuits, or a common-base circuit with an inverted Darlington transistor, or a plurality of series connected common-base circuits with inverted Darlington transistors are connected to an output current path of any working points of any amplifier circuit. The circuit generates a high-impedance hi-fi circuit and a high-impedance BTL circuit, and a plurality of series connected common-base circuits are connected to a current path from output current to load of a common emitter circuit on a large scale to generate an ant circuit. The invention also provides a brand new electronic device of an integrated ant circuit-a high impedance tube, which provides a guarantee of devices for the high-definition speaker. The speaker using the high-definition circuit, the ant circuit and a class A single-end power amplifiercircuit has sweet timbre, environmental protection, energy saving, and natural timbre effect, and better solves the difficulties of high voltage, high gain, high impedance and high power output.
Description
technical field [0001] The invention relates to an audio circuit, more specifically a high-definition circuit for high-definition audio and a series of application circuits thereof. Background technique [0002] Audio is a device that uses electrical signals to restore natural sounds in human activities. Existing high-fidelity audio system generally mainly is made up of high-fidelity circuit, loudspeaker and supporting connecting wire. Among them, the high-fidelity circuit has the characteristics of low output impedance, which is convenient for obtaining larger output power. However, because its power tubes are mostly connected in parallel with multiple tubes and the output follows the output, the output impedance is too small (R≈8Ω), resulting in the sound of the high-fidelity audio system being slightly light, floating, thin, pointed, hard, divergent, Rough, hazy background, and the whole machine consumes a lot of power (generally hundreds of watts), and the noise seriou...
