Software that turns a computer into a speaker machine.
From a physical point of view, this is impossible, that is to say, there is no such software. At present, I am using the speaker machine to connect the homemade speaker, and the sound source is the computer. If you simply need reverberation (technically called reverberation), you can use the software to adjust the reverberation effect by recording the tracks first.-Software Type: Software name: microphone reverberation effector echo V1.0 Green Edition. Rar update time 2006-07-31 Software size 437 KB Software introduction: when singing and entertaining We often have to use an effector to achieve a certain professional level. We usually sing at home and KTV.-software implementation, unless the sound is handled well. Or soft sound card, the effect is not very good. In general, you need an independent sound card to simulate the effects of the sound field. in addition, you need to have high-power active sound. If you have a speaker, you can buy a 3.5MM adapter to connect the output of the sound card to the power.-then you first need to have a 5.1 audio and video system. At the same time, the computer’s MIC interface does not support echoes, and there are echoes that come out of the software difference. Maybe it’s even worse-I want to, too.
Why is there a difference and sound quality difference between gallbladder machine and stone machine?
The reason is that the output impedance and current gain are different.
In order to get a good sound effect, the transistor power amplifier must have lower output impedance, larger current gain, large enough working current and high power supply voltage and good transient effect.
Power amplifier shunt machine and stone machine, stone machine is divided into type A power amplifier and class B power amplifier The working point of the power amplifier tube of the stone machine is selected in the linear amplification area of the tube, so even if there is no signal input, the tube also has a large current flow, and its load is an output transformer, which is easy to produce distortion due to large current when the signal is strong. The power amplifier circuit has the advantages of low efficiency, small dynamic range and poor frequency response characteristics.
Class B power amplifier, the power amplifier tube of this kind of power amplifier circuit works in class B state, that is, the working point of the tube is selected in the microchannel state, and the two amplifying tubes amplify the positive and negative half cycle of the signal respectively, and then the output is synthesized by the output transformer. Therefore, the currents of the two groups of coils flowing through the output transformer are in opposite directions, which greatly reduces the magnetic saturation of the output transformer.
This kind of power amplifier not only improves the efficiency of the amplifier, but also greatly improves the dynamic range of the amplifier, and greatly improves the output power.
Gallbladder machine (electronic tube machine) is sought after by many audio lovers because of its soft and pleasant sound quality. The differences of gallbladder transistors are as follows: the circuit structure of transistors is more complex than that of electron tubes.
The transistor is easily affected by temperature, but the temperature has little influence on the tube; the transistor works in the state of low voltage and high current, so the requirement of power supply is high; while the requirement of power supply of electron tube working in the state of high voltage and low current is relatively low.
The advantage of transistor machine lies in high current, wide band, low frequency control, analytical power, layering and brightness when dealing with large scenes, but the treble of the transistor machine is smoother and has enough air sensation. it has a kind of sound staining that a considerable number of people like, although the sound details and levels are less, but the soft and slightly vague sound is beautiful.
Extended data
The electronic tube is a kind of electronic device working in the state of high voltage and low current, its input impedance is much larger than that of the transistor, it can achieve a better impedance match with a variety of signal sources, and the sound is more stretched naturally; because it works under the high voltage of hundreds of volts, the power amplifier made with it has the characteristics of large voltage dynamic range, not easy to produce clipping distortion and good sound field extension.
The electronic tube has a strong ability to withstand overload, even if it inadvertently inputs a very strong signal in use, it is not easy to break through the short circuit and damage the electronic tube instantly. The characteristic curve and parameters of the same type and batch number of electronic tube are in good agreement, even if the damage occurs, interchange is also very convenient.
Because the gallbladder machine is connected to the field speaker through the output transformer, the output transformer can be regarded as an electric coil. When the impedance end of the output transformer is selected correctly, it is easy to achieve better signal coupling with the voice coil of the loudspeaker (which is also equivalent to an inductance coil). Even a small-caliber horn can get a fuller sound. Therefore, some small bookshelf cases with low efficiency and difficult to drive by transistors are very beautiful with gallbladder machine push.

Who knows what a packing machine is and what it is for?
In the back-end packaging of food and beverage, the automatic packing machine automatically arranges the filled packaging, loads it into the open carton, and completes the self-adhesive sealing and other actions of the packing equipment.
The packing machine can be divided into fully automatic and semi-automatic packing machine. All the actions are completed automatically. The fully automatic packing machine adopts a new type of combined structure, including box forming device, whole line device, filling device and sealing device and other functional units, which complete the corresponding functional actions respectively, and each device is installed on the same mainframe. It is controlled by P.L.C + touch screen. Equipped with missing bottle alarm stop, no bottle without packing safety device. It is greatly convenient to operate, manage, reduce production personnel and labor intensity, and is an indispensable equipment for automatic scale production.
Packing machine can also be divided into: wrapped packing machine, pneumatic packing machine, grab packing machine, robot packing machine.
The wrapping packing machine adopts the falling packaging mode, occupies a small area, reduces the equipment investment cost, adopts the international design concept, the structure is more reasonable, the action is more light and stable, and the power consumption is lower.
The pneumatic packing machine has the advantages of small size, beautiful appearance, low energy consumption, stable operation and convenient operation. The conveyor is driven by imported rodless cylinder, which runs smoothly and has high controllability.
The packing machine with pneumatic and electric operation and packing mode has the advantages of compact structure, beautiful appearance, low energy consumption and stable operation. The driving device is a symmetrical double rocker arm, which is driven by Japanese MITSUBISHI servo motor or three-phase asynchronous motor and runs smoothly.
The robot packing machine is a set of intelligent control system which takes the robot as the running main body and is equipped with conveying and regularization auxiliary equipment to complete the product packing process. The robot packing system has many advantages, such as strong product adaptability, strong multi-specification compatibility, high operation efficiency, convenient system maintenance and so on. Compared with the conventional packing equipment, the robot packing system is simpler and faster.
