The damping short circuit ring is attached to a circuit board of a sound system such as a front stage and a CD player, a rear back plate of a digital player sold in commerce, and even the back of a mobile phone shell; the position close to the audio processing circuit in the circuit can improve the tone quality and increase the tranquility of the background; meanwhile, the method can be used in a processing system of the pulse signal or a digital circuit, improve the quality of pulse signal processing, reduce distortion and reduce error codes.
Description
Technical Field
The additional device improves the impulse response performance of the electronic circuit, improves the damping of the electronic circuit through electromagnetic coupling mapping, can improve the leading edge and trailing edge response of the impulse signal of the electronic circuit, and reduces transient distortion or noise. The circuit used for sound equipment such as front stage or CD player can improve the sound quality and increase the quietness of the background. Meanwhile, the method can be used in a processing system of the pulse signal or a digital circuit, so that the quality of the pulse signal is improved, the distortion is reduced, and the error code is reduced.
Background
In the prior application of the invention patents (application numbers 201810390443.4 and 201910047075.8), designs for damped shorting rings for moving coil speakers or earphones, moving iron speakers or earphones, and transformer inductors are disclosed. These designs efficiently apply damping to the voice coil of a speaker or the coil of a transformer inductor by the electromagnetic coupling mechanism of the loosely coupled transformer principle, improving the impulse transient response characteristics of the speaker and the like: the rising speed of the front edge is increased, the oscillation of the back edge or the relaxation oscillation is reduced, and the transient distortion is obviously improved. The practical use effect is obvious, and the practical application is started to be used on a loudspeaker and various earphones.
Disclosure of Invention
In practice, it has been found that the damping short circuit ring is attached to the circuit board of the sound system, such as the front stage, CD player, the back plate of the digital player sold commercially, or even to the back of the mobile phone case; the sound quality of replay can be obviously improved, the signal-to-noise ratio is improved, and the quietness is improved when the circuit is close to the position of an audio processing circuit in the circuit.
Further research shows that in an electronic circuit, the electric signal is often a pulse signal or a digital square wave signal, and in the signal transmission process in the circuit, an electronic damping characteristic also exists. When the damping is insufficient, there is also a relaxation oscillation problem similar to that of the loudspeaker-like mechanical elastic system, but now of the electronic elastic system. The improvement of the electronic damping of the circuit and the suppression of relaxation oscillation are a key part of the design of the pulse electronic circuit. The damping short-circuit ring arranged close to the electronic circuit forms electromagnetic coupling with the electronic circuit, part of an electromagnetic field generated by pulse current in the electronic circuit can penetrate through the short-circuit ring, and induced electromotive force is generated in the short-circuit ring to drive the short-circuit ring to move or vibrate. The short-circuit ring is completely coated by high-damping material, and the energy of the movement or vibration of the short-circuit ring is quickly converted into heat energy by the damping material to be dissipated. Thus, the stored energy contained in the relaxation oscillation of the pulse signal in the electronic circuit is coupled into the short-circuit loop and dissipated quickly, which is equivalent to that the electronic circuit is coupled to apply strong electronic damping. Thus, the impulse response characteristics of the circuit after the addition of the damped short-circuit loop are improved, similar to what happens in loudspeakers: the rising speed of the front edge is increased, the falling speed of the rear edge is increased, and the transient distortion is reduced. After a damping short-circuit loop is added in an audio circuit, the subjective audibility is improved, namely, the tone quality is improved, the signal-to-noise ratio is good, the tranquility is high, and the stereoscopic impression is strong. In the digital circuit, 0/1 digital signals represented by pulse square waves are transmitted and processed, the damping of the damping short-circuit ring is mapped onto the digital circuit by electromagnetic coupling, so that the back edge relaxation oscillation of the square wave pulses can be inhibited, and the beneficial technical effects of improving the signal-to-noise ratio and reducing the bit error rate are achieved.

And the motion of the short circuit ring is strongly damped by the damping material coated outside the short circuit ring, so that the energy dissipation is rapid. Therefore, the energy of the relaxation oscillation of the back edge of the pulse signal in the circuit is coupled and dissipated, namely, strong damping is added in the circuit, and the relaxation oscillation is restrained and weakened.

There are two short-circuit loops and/or short-circuit coils 1.3 and 1.4 and three layers of damping material 1.1, 1.2 and 1.5.

The structure of the more layers is simply further stacked and can be easily derived from the relationship of this figure and figure 1.

In this case, the damping short-circuit rings simultaneously act on the digital signal processing circuit part and the analog signal amplification processing part, and the two damping short-circuit rings are respectively close to the digital signal processing part and the analog signal processing part of the player. The method is only a preliminary test, and actually, the shell of the player is opened, and the damping short-circuit ring is directly added on an internal digital circuit and an internal analog circuit, so that the effect is better.
