Solution Overview

Problem

High Fidelity (Hi-Fi) and High Fidelity High End (Hi-Fi High End) audio and/or video reproduction systems experience alterations and distortions due to external and internal electromagnetic stresses in low and very low voltage electrical power supply systems, which current devices fail to completely address, affecting both the quality and reliability of the reproduction and safety of the systems.

Innovation Solution

An apparatus comprising a tuner-damper core with a mixture of piezoelectric, pyroelectric materials and semiconductors, integrated with a grounding system and heat dissipation bar, is connected to the electrical power supply system to detect and transform electromagnetic disturbances into mechanical and thermal energy, thereby preventing distortions in audio and video reproduction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If current devices operate downstream of the power supply to eliminate disturbance phenomena, then audio and video reproduction quality is improved, but the devices cannot completely solve the problem of electromagnetic stresses and distortions

Engineering Contradiction:
Improvereproduction qualityVSAvoiddistortion prevention completeness
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The apparatus is connected immediately upstream of the power supply inputs to prevent electromagnetic disturbances before they enter the audio/video system. By acting preemptively at the power input stage rather than downstream, the device blocks disturbance phenomena at their source, ensuring both high reproduction quality and complete distortion prevention.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The apparatus serves as an intermediary device between the electrical power supply system and the audio/video reproduction system. It mediates the electromagnetic stresses by filtering and conditioning the power input, thereby protecting the downstream equipment from disturbances while maintaining optimal reproduction quality.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If selective (atomistic) approach is used to treat disturbance phenomena, then specific disturbances are addressed, but synergistic effects of electromagnetic stresses are not completely eliminated

Engineering Contradiction:
Improvespecific disturbance reductionVSAvoidsynergistic effect elimination
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The apparatus employs a universal filtering mechanism that addresses multiple types of electromagnetic disturbances simultaneously. Rather than treating specific disturbances separately, the device provides comprehensive protection against all synergistic effects of electromagnetic stresses through its integrated circuitry designed to handle various frequency ranges and disturbance types.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

By connecting upstream at the power input stage, the apparatus preemptively prevents all electromagnetic disturbances from entering the system. This preliminary action captures both individual and synergistic effects of multiple disturbance sources before they can interact and create complex electromagnetic stress patterns within the audio/video equipment.

Inventive Principle:
Principle #10Preliminary action

AI summary

Apparatus (1) and method for preventing audio and/or video alterations and distortions with origin external and internal to the electrical power supply systems (100) at low or very low voltage, in alternating or direct current, comprising an external casing (4) having, internally its own containment compartment, an internal (3) and external (8) tuner-damper core. The internal tuner-damper core (3) has a first and a second polar electrode (5) and (6) connected to a respective Phase input (in) (2a) and Neutral input (in) (2b) to receive an electrical voltage signal, and is selectively configured in two embodiments: one comprises a mixture of a non-hygroscopic consolidated sediment (3a); the other comprises a mixture of an incoherent (dissolved), non-hygroscopic sediment (3b). In both embodiments the core (3) determines a first (main) high-frequency (HF) chamber. The external tuner-damper core (8) comprises a mixture of an incoherent (dissolved), non-hygroscopic sediment (8a), bordering and integrated with the internal core (3), and determines a second (complementary) high frequency (HF) chamber.
