Embodiment 1
[0031] Embodiment 1: A processing circuit for improving the performance of audio equipment, the positive power supply wire 10 at the input end of the audio host 1 is connected in series with a fuse F1 with filtering function, the positive power supply wire 10 at the input end of the audio host 1 and the input A capacitor C is connected across the negative power supply wires 11 . The positive power supply wire 10 of the input terminal of the audio host is connected to the positive pole of the power supply 9, and the negative power supply wire 11 of the input terminal of the audio host is connected to the negative pole of the power supply 9
[0032] The fuse F1 with filtering function includes a metal wire 2 and a tube body 3, the metal wire 2 is arranged in the tube body 3, and the tube body 3 is filled with granular radio wave absorbing material 4, and the particle size of the radio wave absorbing material 4 is 50 mesh . The radio wave absorbing material 4 is composed of 40% ...
Embodiment 2
[0041] Embodiment 2: The other parts are the same as Embodiment 1, except that the particle size of the radio wave absorbing material 4 is 100 mesh. The radio wave absorbing material 4 is composed of 50% by volume of quartz crystal mixed with 50% by volume of dopant, and the capacity of the oil-immersed capacitor is 5uf. The damping material 16 is graphite.
Embodiment 3
[0042] Embodiment 3: The other parts are the same as Embodiment 1, except that the particle size of the radio wave absorbing material 4 is 200 mesh. The radio wave absorbing material 4 is composed of quartz crystal with a volume percentage of 70% and a dopant with a volume percentage of 30%. The capacity of the oil-immersed capacitor C is 10uf. The shock-absorbing material 16 is a mixture of butyl rubber and metal.
