Embodiment Construction

[0028] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0029] Such as figure 1 As shown, an audio electronic tube with a composite anode provided in this embodiment includes: a glass shell 1, and an anode, a cathode 5, a grid 4, a stem 14, upper and lower spacers, and a top set in the glass shell. Sheet 3, lead-out wire, getter ring, and tube base 13 at the lower part of the glass shell, the anode is composite anode 2 formed by lamination of molybdenum mesh and graphite;

[0030] Graphite is a hollow body structure with a waist-shaped cross-section of the inner cavity and an approximate shape of the outer contour cross-section. The inner and outer sides of the straight waist-shaped graphite are equipped with molybdenum mesh;

[0031] Flaky grooves are provided on the inner wall of the waist-shaped straight side of the graphite, and the molybdenum mesh 22 on the inner wall is matched with the groove and welded...

Abstract

The invention provides an audio electronic tube with a composite anode, comprising a glass tube shell, an anode, a cathode, a grid, a core column, an upper and lower spacer plates, a top sheet, a leadwire, a degassing agent ring, and a tube base of a lower part of the glass tube shell, wherein the anode molybdenum net and graphite are superposed to form a composite anode. The invention has simplestructure and good sound performance.

Description

technical field [0001] The invention relates to a vacuum type electronic tube, in particular to an audio frequency electronic tube with a composite anode. Background technique [0002] At present, the main technical indicators of sound-quality audio tubes, most of the tube products are due to the unreasonable structural design of their anodes and related parts, resulting in complicated production processes, troublesome installation, and poor sound performance. [0003] Therefore, it is necessary to provide a new audio tube with a composite anode with reasonable structural design to solve the above problems. Contents of the invention [0004] The purpose of the present invention is to provide an audio electronic tube with a composite anode, which is easy to assemble, has a long life, and has more comprehensive and balanced sound performance. [0005] The invention provides an audio electronic tube with a composite anode, comprising: a glass shell, and an anode, a cathode, ...
