Description

Technical Field

[0001] This utility model belongs to the field of electron tubes, specifically relating to a small audio electron tube. Background Technology

[0002] Vacuum tubes are one of the earliest electrical signal amplification devices. The cathode electron emitting part, control grid, accelerating grid, and anode leads are all enclosed in a glass container and soldered to the tube base. An electric field is used to inject electrons into the control grid in a vacuum to modulate the signal, and different parameter signal data are obtained at the anode after signal amplification or feedback oscillation. Now, with the continuous development of technology, vacuum tubes are generally used in various audio equipment as low-noise, high-stability audio power amplification devices.

[0003] In practical use, the outer glass container of modern audio tubes is generally cylindrical, which helps to evacuate the tube and ensure that the inside of the tube is in a vacuum state. However, there are some problems in actual use. Although cylindrical glass tubes are easy to process, when the tube amplifies audio power, the overall frequency of the sound playback is limited, and the timbre after playback is not smooth enough, which affects the performance of the device.

[0005] To address the problems mentioned in the background section, the present invention adopts the following technical solution.

[0006] A small audio tube includes a mounting base, a tube shell, and a tube body. The tube shell, which ensures a vacuum inside the tube, is mounted on the outside of the mounting base. The tube body, which provides power amplification, is mounted on the surface of the mounting base. The tube shell includes a middle glass layer, a bottom glass layer, and a connecting glass layer. The bottom glass layer is mounted on the outside of the mounting base, the middle glass layer is mounted on top of the bottom glass layer, and the connecting glass layer is mounted on top of the middle glass layer.

[0007] As a preferred embodiment of the present invention, the electron tube shell further includes a protruding end, which is installed on the top of the connecting glass layer and is a cylindrical structure with a protruding bottom opening and a sealed top.

[0008] As a preferred embodiment of this utility model, the middle glass layer, the bottom glass layer, the connecting glass layer, and the protruding end are integrally formed.

[0009] As a preferred embodiment of this utility model, the electron tube body is composed of an anode, a cathode and a grid, and the internal components of the electron tube body are electrically connected to the end of the mating seat.

[0010] As a preferred embodiment of this utility model, the mating seat includes a sealing seat and a connecting pin. The sealing seat is installed at the bottom opening of the electron tube shell, and the connecting pin is installed at the bottom of the sealing seat.

[0011] As a preferred embodiment of this utility model, the connecting pins penetrate the sealing seat and are electrically connected to the internal circuit components of the electron tube body.

[0012] As a preferred technical solution of this utility model, the connecting pins are divided into multiple groups, consisting of a single ground pin, two cathode pins, two grid pins, two plate pins, and two filament pins.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In this invention, by setting up a tube shell and a mating seat, the shape and structure of the traditional tube shell are changed. By using the protruding part at the top and the gray graphite emulsion or black carbon powder coated on the outside of the protruding part, the overall tone of the tube is enhanced, making the sound emitted by the device more mellow and warm compared to the original product, thus improving the overall working quality of the device.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0024] Depend on Figure 1 and Figure 2 As shown, this is a schematic diagram of the structure of the small audio tube in this embodiment, including a mounting base 1, a tube shell 2, and a tube body 3. The mounting base 1 is externally mounted with the tube shell 2 to ensure the vacuum inside the tube. The tube body 3 with power amplification is mounted on the surface of the mounting base 1. The tube shell 2 includes a middle glass layer 21, a bottom glass layer 22, and a connecting glass layer 23. The bottom glass layer 22 is mounted on the outside of the mounting base 1, the middle glass layer 21 is mounted on the top of the bottom glass layer 22, and the connecting glass layer 23 is mounted on the top of the middle glass layer 21.

[0025] During use, the cooperation between the electron tube shell 2 and the mating seat 1 forms a sealed, vacuum space inside the electron tube, providing a stable environment for the operation of the electron tube body 3. Then, with the cooperation of the electron tube body 3, the flow rate of electrons can be easily controlled, the input signal can be connected to the grid, and an appropriate bias voltage can be applied. A resistor is connected in series with the plate, thereby achieving the purpose of amplifying the electrical signal. The electron tube shell 2 is composed of a middle glass layer 21, a bottom glass layer 22, and a connecting glass layer 23, which wraps and protects the mating seat 1, ensuring the stability of the equipment during operation.

[0026] From the appendix Figure 3 As shown, it is a structural schematic diagram of the electron tube shell 2 in this embodiment. The electron tube shell 2 also includes a protruding end 24, which is installed on the top of the connecting glass layer 23. The protruding end 24 is a cylindrical structure with a protruding bottom opening and a sealed top.

[0027] During use, the installation and use of the protruding end 24 makes the tube housing 2 a closed glass container with an open bottom. Together with the mating seat 1, the tube is completely sealed. The shape and structure of the protruding end 24 itself effectively diffuses and processes the electrical signal excited by the tube body 3, improving the final playback tone. This makes the sound of the audio tube more rounded and warm compared to the original product. Furthermore, the protruding part of the protruding end 24 is coated with gray graphite emulsion or black carbon powder to ensure the stability of the protruding end 24 in actual use and improve the final tone.

[0028] From the appendix Figure 3 As shown, it is a structural schematic diagram of the electron tube shell 2 in this embodiment. The middle glass layer 21, the bottom glass layer 22, the connecting glass layer 23 and the protruding end 24 are integrally processed to ensure the overall sealing effect of the electron tube shell 2 during use, so that the inside of the electron tube is in a vacuum state, thereby improving the stability of the final device during operation.

[0029] From the appendix Figure 3 As shown, the electron tube body 3 is composed of an anode, a cathode, and a grid. The internal components of the electron tube body 3 are electrically connected to the end of the mating seat 1. In use, the electron tube body 3 is composed of multiple sets of components. By utilizing the cooperation of the anode (also known as the plate electrode), the cathode, and the grid, the flow rate of the input electrons is controlled to achieve the purpose of amplifying the electrical signal.

[0030] From the appendix Figure 3 As shown, this is a schematic diagram of the structure of the mating seat 1 in this embodiment. The mating seat 1 includes a sealing seat 11 and a connecting pin 12. The sealing seat 11 is installed at the bottom opening of the electron tube shell 2, and the connecting pin 12 is installed at the bottom of the sealing seat 11. In use, the mating of the sealing seat 11 with the bottom of the electron tube shell 2 seals the entire electron tube, ensuring that the inside of the electron tube shell 2 is in a vacuum state, which assists the operation of the equipment. The installation of the connecting pin 12 can transmit electron flow signals to the electron tube body 3 on the surface of the mating seat 1.

[0031] From the appendix Figure 3 As shown, it is a structural schematic diagram of the mating seat 1 in this embodiment. The connecting pin 12 passes through the sealing seat 11 and is electrically connected to the internal circuit components of the electron tube body 3. Through the connection of the connecting pin 12, the electron flow signal is transmitted to each component inside the electron tube body 3, which is convenient for subsequent amplification processing.

[0032] From the appendix Figure 3As shown, it is a structural schematic diagram of the mating seat 1 in this embodiment. The connecting pins 12 are divided into multiple groups, consisting of a single ground pin, two cathode pins, two grid pins, two plate pins, and two filament pins. In use, the multiple groups of connecting pins 12 are installed to cooperate with the internal components of the electron tube body 3 to assist the stable operation of the equipment. In addition, a grounding terminal is added to ensure the stability and safety of the equipment during operation.
