In this article, we will consider the repair of the JBL portable column, as well as how to disassemble jBL Charge 2. Our column disappeared the sound. When you turn on, it does not publish any sounds. The column itself turns on, there is an indication, the buttons react to pressing, the phone is determined. This behavior suggests the thought of a malfunction of the dynamics or output amplifier Z.ch. We try to repair it yourself. Let's start repairs with the selection of tools. We need: a small flat screwdriver for removing the speaker's protective grid, a cross screwdriver and a multimeter. Carefully refer to a flat screwdriver protective grid as shown by arrows in the figure below.
Under the grid we have two speakers, unscrew the screws that hold the speakers.
Give the speakers, carefully disconnect the terminals.
We measure the resistance of the speaker. Must show 8 ohms. If the multimeter showed a break (infinity sign), then the speaker should be replaced. The second speaker is tested in the same way.
We replace the faulty dynamics of workers. You should also check the column fee for availability<<оторванных>\u003e or not removal elements.
Since our wireless column JBL Charge 2 is compact, we often take it with you. As we carefully did not belong to JBL Charge 2 falls, we can not avoid. Consider how to correctly disassemble our column so as not to damage the wires and loops. We have already removed the speakers. Next, consider further disassembly of our column. Unscrew the screws marked with circles in the photo below.
On the other side of the column. There is another protective grid, under the grid there are a battery. And another 4 screws, unscrew them.
We remove parts of the case. And unscrew the screws that hold passive speakers.
As we see in the photo above, the fee appeared. But it is still impossible to remove it. In order to remove the fee, we need to suffer a little more. In the photos below shows how to rejuvenate the rubber panel. From the same side. And also you need to unscrew all the screws that hold the boards and disconnect the loop.
After we disconnected all the loop and unscrew all the screws, we can pull out our fee. The loops that we disconnected from the boards under a rubber band should push into the JBL Charge CHARGE column 2. The board should go easily. If at some point the board stopped easy to go. You still need to check whether we disconnected and twisted. Check the fee. Correct the fault, if found and collect our column in the reverse order. I remind you all work must be carefully carefully and not in rush.
I hope the article Repair of the JBL portable column was useful to someone. Good luck in repair!
Hello respected gentlemen, My name is Paul, I am from the Netherlands. I want to share my project independent manufacture enclosures. Dynamics I acquired in the Netherlands, Germany and Austria.
Original drawing:
Specially made the nozzle for cutting circles:
The material appeared. There are not bad tools in stock, but it is only half of the work:
My garage in it free spacebut filled it quickly:
I used MDF 30 mm thick and 5x60 mm screws. At first I collected the side, upper and lower panels, and glued them with glue. To give the correct rectangle form inside, put a piece of panel:
The next step I collected at the bottom (from the outside) a rectangle that will be legs of the AU. To do this, I used 40x40 mm bars. Bottom I will not cover veneer, but just paint black:
That's what I collected on the components. 2235H 100% from Germany, 2123h or 2122h from Austria, 2425J + Rouger from Beyma. Two different Supervitra 2405n from the Netherlands. Appearance Some speakers were in poor condition, I had to work with them a little:
The next step was to cut holes before which once again made sure that everything in their places. Mounting kit bought on eBay:
Made a sample under the dynamics:
Bought a plastic tube with a diameter of 315 and a length of 600 mm for the manufacture of boxing under Midbas:
Inside the speakers planted on glue and screws of stiffness ribs on all inner walls, as well as additionally for mounting the rear panel:
Under the magnetic system of the horn, the dynamics cut out the panel, which is glued to the struts:
To protect against moisture, the inner part of the case I covered with a primer. The front panel from the outside and from the inside pre-covered in a blue, resembling the branded color of acoustics JBL:
Embedded to the manufacture of the back panel for speakers:
Now it is necessary to finally determine with the choice of the front panel color. RAL5007 is more similar to 43xx series, but I had a feeling that the branded blue was somewhere between RAL5007, RAL5012 and RAL5015. RAL5007 is too violet. RAL5012 is too light. RAL5015 is too blue.
So I started mixing and choosing something between the options received. I chose the three "best" options:
№4: 1/2-5007, 1/4-5012 and 1/4-5015 - Even too blue;
№5: 1/2-5007 and 1 / 2-5012 - too light;
№7: 3/4-5007, 1/8-5012 and 1/8-5015 - too violet.
As a result, I narrowed a triangle, and chose between №13: 0.6 × 5007, 0.3 × 5012 and 0.1 × 5015. Such a choice may be controversial, but I like the color:
Production of phase inverters and their internal colors in the already selected color JBL:
The inclusion scheme and photo technique that will be used with acoustics. FROM pre-amplifier The signal goes to the active crossover, which divides the signal into two bands. After that, each strip is enhanced by a separate amplifier, the signal from the amplifier goes directly, and on the Foreign Ministry, Sch and HF - through a passive filter:
Filters made in separate enclosures for each channel:
Offered by modern manufacturers acustic systems strike the variety of functions and the scope of possibilities.

- From power portable acoustics The maximum volume of sound depends. Truth, at power close to the maximum, any system begins to give more distortion in sound.
- The range of reproducible frequencies affects the dignity of the sound of music. The greater the value of the maximum frequency, and the less minimal, the better.
- On the quality of the sound of portable acoustics affects the number of strips. What they are more, the clearer will pass the sound. In most cases, in portable devices one or two bands.
- High-quality sound transmission depends on the signal / noise ratio. The higher this value will be, the less distortion will produce a built-in amplifier.
Video
For a long time caused ambiguous responses of specialists and ordinary users. On the one hand, such systems give obvious advantage Due to the possibility of free displacement and independence from wired energy supply. But on the other, the compact dimensions and nutrition from the battery elements still limited the sound quality of the equipment. Change the current idea of \u200b\u200bthis concept was securely presented in several versions. Such devices are not only distinguished by worthy qualities of playback of compositions, but also ergonomics and original design.
General information about portable JBL models
The latest models of the portable device lineage JBL significantly improved in various directions - from the smallest in design before introducing new technologies like the Bluetooth wireless module. What is important: the JBL portable column is still of interest in the point of view of sound quality. The manufacturer does not miss the use of expensive materials of the element base, which allows acoustics along with mobility support to also enjoy listening to music.
Special attention developers pay the structural execution of models. Most modifications of this type have a cylindrical form factor, which improves the convenience in the process of physical exploitation. In addition, the JBL portable column is distinguished by the presence of a rubberized shell for easy grip. The output places of the speakers are accumulated in the housing niche, which increases and reliability in use. In other words, the design is calculated not just on mobile circulation, but also focuses on the active lifestyle of the user. The columns can be mounted on the bike frame, place the backpack outside or put on any flat surface.
The main characteristics of the portable acoustics JBL
Ensure good sound playback features allow operating system performance. In particular, the frequency range is an average of 100-20,000 Hz. And if the upper limit is usually preserved at 20,000 Hz, the lower range varies from 75 to 160 Hz, depending on the model. As for the total capacity, it constitutes a corridor from 3.5 to 15 W. Of course, against the background of full columns, these indicators are not impressive, but it is necessary to make a serious discount on the size of mobile acoustics - for this class and 10 W in total capacity is a very worthy value. The sensitivity in almost all representatives of the line is at one level - 80 dB. Interesting and performance indicator on one charge. Its durability averages 5 hours under active use. Now you can go to a more detailed acquaintance with the advantages and disadvantages of individual models. This will help on the basis of feedback from users themselves.
Reviews of the model JBL Charge
A compact stereo system, which in the portable acoustics family JBL occupies an average position. She is the most popular among brand fans. According to them, the column is characterized by high-quality sound, ergonomic control and the inclusion of the newest technological systems. In particular, the user can find out about the main operational indicators on special indicators located on the housing. Charging is carried out via the USB port, and the battery itself is withstanding for a long time listening to music. If we talk about negative responses, then it is possible to note the modest power that this JBL column is endowed. Bluetooth, in turn, provides stable bundle with others. mobile devicesto which there are no complaints.
Reviews of the model JBL Pulse
This system has a higher power supply, which allows it to better process the full frequency spectrum. The rest of the model causes almost the same reviews as the Charge version. The owners point to the comfort in circulation, the ergonomic form of the case and a number of functional additions. By the way, the portable column JBL Pulse works through a special application iPhoneThanks to which the communication capabilities of acoustics were expanded. But there is some complaints to this model. The main one relates to a modest configuration. So, compared with some models of the same line, the modification of Pulse is deprived of the cable to connect the headset of a 3.5 mm format.
Reviews of the model JBL Clip
Rather unusual and, rather, the utilitarian version of the portable acoustics from the manufacturer JBL, calculated on an unzipping listener. The model has a capacity of 3.5 W, which causes numerous questions to the quality of sound. True, reproduction capabilities in this case Conditions and monocanal playback, so initially it is necessary to understand the value of the basic abilities of the CLIP system. On her background, of course, the JBL Charge portable column looks more profitable, but it is more expensive. Despite this, users still do not recommend refuse to consider this option, since it is also implemented by the same wireless communication capabilities. In terms of assembly quality, there are also no criticism - a durable, small and ergonomic case causes only positive impressions among the owners of the device.
Reviews about the JBL GO model
Another variation of mobile and at the same time of the budget device from JBL. It should be noted that this system does not differ in high power, but, according to users, it gives a surround sound with a good stock. But there are complaints about working wireless communication. In particular, distortion and failures are noted when connecting to third-party devices. It is clear that this reduces all the acoustic advantages that the JBL column possesses. The Bluetooth receiver many disappointed, but the rest of the system manifests itself well. For example, the model has a bright and stylish design that attracts attention. As for the reliability of the hull, it is endowed modern systems protection, so confidently copes with external negative impacts.
Question price
Two latest models The review can be acquired on average for 2-4 thousand rubles. Even on the background of budget analogues from little-known manufacturers This price tag is more than attractive. Another thing is that in these modifications there are not the best operational properties of products of this manufacturer. But the question is how much the JBL portable column is, perhaps, many will reheave many for another reason - for example, the Pulse version is available for 11-12 thousand. According to even those who are completely satisfied with this model in working qualities, the price tag is very high and not justifies the purchase.
How to choose an optimal model?
The company offers several series of portable speakers, but they all have a lot of similar features. This refers to the style of design, ergonomic characteristics, assembly quality, etc. The choice will have to do on the criteria of sound and form factor. If you need a JBL portable column for listening "on the go", that is, it makes sense to stay on budget versions that cost cheaply, but it is guaranteed reliability and durability. For music alone, the Pulse and Charge models are suitable, and the second option provides quite good quality, but it is twice as cheaper. The choice is also individual, but here it is necessary to count on the conditions of operation. A cylinder column will be a universal option, and if it is planned to use the model of the house, it is necessary to prefer the GO in the classical design of the structure.
Conclusion
Low sound quality in portable speakers was previously due to small size speakers. Actually, this problem is not doing anywhere, and still developers of acoustics have to be labby between the quality of reproduction and mobility of the device. The company continues to demonstrate success in search of this balance, but at the same time successfully solves another problem - signal broadcast via the JBL wireless module. Portable column whose bluetooth receives high-quality sound - This is a rarity, but in this case, users note the organic combination of portability and the implementation of wireless communications. Of course, the full comparison of the possibilities of Bluetooth and high-quality acoustic cables does not go, but the difference between them is reduced. This is worth adding both improvements that expand the universality of portable systems. For example, the CHARGE model in newest versions It is capable of simultaneously connecting to three devices via a wireless module channel.
