REPOSAL®winding machine special winding machine for frequency divider inductors
In daily life, have you ever noticed more than one horn on your car? And more expensive cars have more horns. According to normal people's thinking, the car as long as there is a horn can emit sound signals on the line, more horn is why? The reason is very simple, for example, the turn signal and the warning horn are completely different, the sound frequency is different, and the sound range of the speakers used for high and low is naturally different. A single speaker cannot play a full frequency sound, and a sound may require a combination of multiple channels of sound to achieve a clear cue.
Therefore, in order to make each speaker emit audio suitable for it, it is necessary to use a tool such as a frequency divider. In simple words, the frequency divider is a filter circuit composed of a capacitor and a frequency divider inductor coil wound by the frequency divider winding machine. The capacitor filters the low frequency to the tweeter, and the frequency divider inductor is wound by the frequency divider winding machine to filter the high bottom to the low frequency to the woofer, so as to distinguish the sound signals in different frequency bands in a sound. It has different sound frequency channels, high frequency sound channels can only pass high frequency sound, middle and low frequency sound the same. After the sound is distinguished, the sound is amplified and played in the corresponding sound amplifier, and finally we can get the most accurate audio we want.
Frequency dividers are divided into two categories, one is a power divider, and the other is an electronic divider.
The power divider is set in the speaker, the power amplifier in the speaker first amplifies the sound power, and then the power divider divides it into three audio signals, high, middle and low, and finally sends it to different speakers for playback. The advantage of this power divider is that it is simple and convenient to connect and use, but its disadvantages are also obvious, that is, its power consumption is large and the parameter deviation value is large, the error of the sound frequency is large, and its error is related to the impedance of the speaker, so it is not convenient to adjust.
In order to play audio more flexibly, we have produced electronic frequency dividers. The electronic frequency divider first distinguishes the audio signal, then amplifies it in different power amplifiers, and finally sends it to the corresponding speaker. The electronic frequency divider has the advantage of low loss and easy adjustment. The power amplifier and the speaker are directly connected, the interference between the speaker units is small, the signal frequency is independent, the signal frequency interference is small and more accurate, and the sound quality is clearer. This disadvantage is that each of the distinguished sound frequencies must have an independent power amplifier, which is costly and the circuit is relatively complex.
Here we focus on the electronic frequency divider, through the above content we have a general understanding of some, followed by a more in-depth analysis of its characteristics.
Nowadays, there are many kinds of speakers and complex, and the electronic divider to be used should also be flexible, such as 2 dividers, 3 dividers, 4 dividers, etc., as the name suggests, the frequency of the audio is divided into several files.
The use of a frequency divider also ensures the efficiency of the speaker to a certain extent. Because the working frequency of different speakers is different, different frequencies of audio have to use different caliber speakers to play a good effect, such as low frequency sound with a large caliber speaker effect is better, and the medium frequency on the contrary to use a small caliber speaker. Such a variety of loudspeakers in order to work efficiently and safely, it is necessary to use the electronic frequency divider to provide the appropriate audio, frequency divider in addition to the frequency divider sound can also protect the speaker, in this process, the professional frequency divider inductance winding machine wound high quality frequency divider inductance is indispensable.
Of course, the most fundamental is to increase the level of sound through the use of electronic frequency dividers. If several speakers play full frequency signals, different speakers play different effects because of the difference in speakers, the sound will be messy and fuzzy, and a variety of overlapping in a piece affects people's hearing. The sound after the frequency division can make different speakers emit different and appropriate sounds, the frequency of the sound is not repeated, the sound will not interfere with each other, people will listen more clearly and feel more deeply.
There are advantages and disadvantages, and electronic frequency dividers are not completely suitable for all situations. For example, different speakers use different audio, and it is very difficult for people to use electronic frequency modulators to separate audio into audio that is appropriate for each speaker. It takes a lot of care and patience. Therefore, when using electronic dividers, most of them will use frequency division, 3 frequency division, 4 frequency division, and more than 4 frequency division will be too complicated and meaningless, and it is also a big challenge for sound engineers.
The use of electronic frequency dividers will strictly solidify the working frequency of each speaker, limit the use efficiency of the speaker, and waste the original function of the speaker. For example, a speaker can originally use ultra-wide audio, emit a loud sound, the use of electronic frequency divider may be part of the speaker excision, so that the speaker can only emit a high, middle and low one, although the tone will be better, but also waste the original advantages of the speaker conditions. If people need a louder sound rather than a more interesting sound, then it is better not to use an electronic frequency divider.
Improper operation of the electronic divider can cause damage to the speaker. As mentioned above, the use of frequency divider also ensures the efficiency of the speaker to a certain extent and protects the speaker. The inductance of a speaker divider is used to filter the high-frequency signal and leave the low-frequency signal, using an empty core coil without an iron core and a coil with an iron core, and the frequency of the divider is directly related to the inductance, the greater the inductance, the lower the frequency can be, the better the bass effect, but as an industrial product, to wind the ideal divider coil, Under the premise of cost control, the inductance value is required to be accurate, the consistency is high, and the DC resistance is low, so as to ensure that the low frequency is not easy to saturated distortion.

REPOSAL®winding machine's advantages in crossover winding machines
REPOSAL has invested a lot of R&D efforts in the field of crossover coil winding machines and has achieved a series of remarkable results.
In terms of winding accuracy, through in-depth research and optimization of the wiring mechanism and control system, REPOSAL's divider coil winding machine can control the winding accuracy within a very small error range. For example, for the wire with a thin wire diameter, the winding machine can accurately wind according to the set number of turns and arrangement, to ensure that the position accuracy of each turn of wire reaches ±0.05 mm, which greatly improves the quality and performance stability of the coil, and makes the crossover more accurate in the audio signal processing.
In terms of improving winding efficiency, REPOSAL has developed a unique high-speed winding technology. Thanks to the use of an advanced motor drive system and an efficient drive, the winding speed of the winding machine is increased by 30% compared to conventional models. At the same time, combined with the intelligent control system, continuous and uninterrupted winding can be realized, which greatly shortens the winding time of a single coil. For example, a common divider coil that used to take about 10 minutes to be wound by hand, but only 3 to 4 minutes with REPOSAL's winding machine significantly improved production efficiency and provided strong support for large-scale production.
In terms of versatility, REPOSAL's crossover coil winders are highly adaptable. By designing replaceable winding dies and flexible parameter adjustment functions, it is possible to wind a wide range of divider coils with different specifications, shapes and parameter requirements. Whether it's a crossover coil for a miniaturized audio device or a crossover coil for a large professional audio system, high-quality winding can be achieved on the same winding machine. For example, for coil skeletons with different inner diameters, outer diameters and height requirements, the winding machine can quickly switch production modes through simple mold change and parameter setting to meet diverse market needs.
In addition, REPOSAL also pays attention to the research on the convenience and intelligence of the winding machine. A concise and easy-to-understand human-computer interface has been developed, so that operators can master the operation method with only simple training. At the same time, the winding machine also has intelligent fault diagnosis and early warning function, which can monitor the parameters in the winding process in real time, and once there is an abnormal situation, such as wire breakage, abnormal winding tension, etc., it will immediately send out an alarm and prompt the cause of the failure, which is convenient for the operator to deal with in time and reduce the risk of production interruption and equipment damage.
