Do you know what's the vacuum tube?

Bile tubes in audio‌ refer to electron tubes, also known as vacuum tubes. In audio systems, bile tubes are mainly used for power amplification and are the core components of tube amplifiers (tube power amplifiers). Tube amplifiers use tubes to amplify signals and have unique timbre and sound quality.

The working principle of bile tubes is based on the characteristics of tubes. The inside of the tube contains cathodes, grids, and anodes, and the signal is amplified by the flow of current in the vacuum tube. The tube amplifier will produce a certain amount of distortion and warmth during the amplification process, which makes the tube amplifier have a unique charm in music performance.

The role of bile tubes in audio systems
Bile tubes are mainly used for power amplification in audio systems, and can amplify weak electrical signals to a strength sufficient to drive the speaker to sound. Compared with transistor amplifiers, bile tube amplifiers have the following characteristics:

1) High fidelity: When amplifying audio signals, bile duct amplifiers can maintain the original quality of the signal, making the music more realistic, natural, and layered.

2) Warm timbre: Since bile duct amplifiers use vacuum tubes as amplification components, their timbre is warmer and softer, giving people a pleasant auditory enjoyment.

3) Wide dynamic range: Bile duct amplifiers can process audio signals with a high dynamic range, making the performance of bass and treble more outstanding.

4) Good audio detail performance: Bile duct amplifiers have a strong ability to express audio details and can better restore the subtle changes and details in audio signals.

5) Strong durability: Since there are no moving parts inside bile duct amplifiers, bile duct amplifiers have a longer service life than other amplifier devices.

For examlple, our model of TI400, it's the bluetooth speaker with 2 vacuum tubes!

The shape of this speaker is quite special, with a rectangular box and 4 legs, clear lines, simple and modern. At first glance, it looks familiar, and it is quite similar to many small items in IKEA.

Its front is a whole piece of detachable cloth mesh and acrylic sheet, and the rest of the shell is MDF wood surrounded by PVC

There are 5 volume knobs on the top, and the knobs are very light to turn, with almost no resistance, representing the total volume adjustment, treble adjustment, bass adjustment, mixing adjustment, and microphone volume adjustment

There are several sockets on the back. It is worth mentioning that it has an HDMI ARC interface that can be connected to a TV. There is also an optical fiber interface.

The biggest feature of this speaker is that there are two customized vacuum tubes in the front, that is, electronic tube amplifiers, commonly known as "tube amplifiers". Tube amplifiers are the old and enduring "evergreens" in the audio industry. Its appearance makes the speaker more retro.

In terms of audio, this speaker uses two 4-inch woofers and uses DSP sound processing technology. Its sound quality is quite distinctive, it sounds mellow and warm, and at the same time has a touch of gentle lines, which is especially suitable for slow-paced pure music or vocal solos.

Overall, the appearance of this speaker is simple and modern, it looks very young, very fashionable, very IKEA, and the style is versatile. If you give it to a friend as a work of art (such as a Christmas gift), it is a very special thing. Its vacuum tube is the most colorful part of the whole machine, and the retro feeling and tube-flavored sound quality are all reflected in a small vacuum tube. It is precisely because of the appearance of the tube that its listening experience is slightly different from that of ordinary speakers.
