Embodiment Construction

[0008] See above-mentioned accompanying drawing as can know the structure of the present invention: its anode is by the hollow anode 3 that two kinds of arched semi-anodes 1 and 2 that are made of different anode materials are combined, and arched semi-anode 1 is iron-nickel alloy reticular The arched half anode, the half anode 2 is an arched half anode made of graphite material.

[0009] The iron-nickel alloy mesh arched semi-anode can be an iron-nickel alloy mesh electron trap arched half-anode, and its wall thickness is 0.2-0.25mm. The wall thickness of the arched semi-anode made of graphite material is 2-3mm. . The inner widths of the arches of the two arched semi-anodes are the same. The size of the two arched half anodes is the same.

[0010] The present invention has no special requirements on its technique and production utensils.

Abstract

The invention relates to an audio electronic tube, in particular to an anode of an audio electronic tube. The anode is a hollow anode 3 compounded by two arch half anodes 1 and 2 made of two different materials, wherein the arch half anode 1 is an iron nickel alloy reticular arch half anode, and the arch half anode 2 is a graphite arch half anode. The utility model has the advantages that the anode of the utility model is adopted as the anode of the audio electronic tube, and thus the tones of the high, middle, and low audio frequencies of the audio electronic tube are better and more satisfactory than the tone of the prior audio electronic tube.

Description

technical field [0001] The invention relates to an electronic tube for audio, in particular to an anode of an electronic tube for audio. Background technique [0002] The sound quality of the electronic tubes in the existing power amplifiers in use is difficult to meet people's requirements for the sound quality of high, middle and low frequency bands. The high-frequency sound quality of the screen material anode of the audio tube is good, but its middle and low-frequency sound quality is not ideal. The sound quality of the metal sheet material anode and the graphite material anode of the audio tube is good in the middle and low frequency bands, but the sound quality in the high frequency band is not ideal. Contents of the invention [0003] The object of the present invention is to provide an anode for an audio tube with good sound quality in the high, middle and low frequency bands in view of the above-mentioned defects in the prior art. [0004] The technical scheme o...
