Conventional amplifiers simulating vacuum tube characteristics are unable to output waveforms exceeding the power supply voltage, limiting their ability to replicate the distinctive waveform features of vacuum tube amplifiers.
Innovation Solution
The proposed amplifier incorporates a jumping-up circuit with diodes and capacitors connected in series between the amplifying circuit and the speaker load, which includes an inductor, diodes, capacitors, and a resistor, allowing for overshooting and undershooting peaks that exceed the power supply voltage, mimicking the resonance and damping effects of vacuum tube amplifiers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional amplifier circuit is used to simulate vacuum tube characteristics, then the circuit can reproduce the general waveform shape, but the output waveform cannot exceed the power supply voltage
Solution Approach 1:
The patent introduces a jumping-up circuit as an intermediary component between the amplifying circuit and the speaker load. This circuit includes an inductor connected in series with a capacitor and diode arrangement, which acts as a mediator to transfer and transform the electrical energy, enabling the output voltage to exceed the power supply voltage while maintaining waveform accuracy
Solution Approach 2:
The patent changes the electrical parameters of the circuit by introducing reactive components (inductor and capacitor) that can store and release energy. The inductor's inductance and the capacitor's capacitance are selected to create resonant conditions that produce voltage overshoot, allowing the output waveform to exceed the power supply voltage level
2Power
If a jumping-up circuit is added to enable output exceeding power supply voltage, then waveform peak values can exceed power supply voltage, but the circuit complexity increases
Solution Approach 1:
The patent divides the amplifier system into distinct functional segments: the amplifying circuit section and the jumping-up circuit section. This segmentation allows each part to perform its specific function independently - the amplifying circuit handles signal amplification while the jumping-up circuit handles voltage overshoot generation, making the overall complex system manageable and modular
Solution Approach 2:
The patent combines multiple passive components (inductor, capacitor, diode) into a single integrated jumping-up circuit module that is connected in series between the amplifying circuit and speaker load. This merging approach achieves the voltage overshoot function using a compact arrangement of components rather than separate distributed elements
