Wireless Device and Repair

One once for the repair I was brought by a wireless bluetooth column. Speed \u200b\u200bshe had a decent appearance. On the box it was written by JBL Charge 3. Googled. From that yes! Column for 8 thousand. Cool. But, as it began to understand with her, then the doubt immediately appeared that it was really JBL Charge 3.

He took off the protective casing and began to be surprised at how Syo's creation was made. Compared with the original on the pictures and realized that I had a cheap Chinese fake, a replica, a copy.

Compare with the original This creation makes no sense, the difference is colossal. Many want to buy a Bluetooth-column JBL Charge 3 on Aliexpress cheaper and fall on a copy, a replica. For example, this can be purchased. Costs about 3000 rubles. Apparently, such a copy came to repair.

Well, the original Wireless column JBL Charge 3 is sold on Ali in the Tmall store. Its price is not much different from the one on which large network shops are made. So, if you want to buy the original, then do not chase at low price, the original costs 7-8 thousand rubles.

To begin, I want to say that one of the most running breaks of such devices is the broken MicroUSB connector. It is with such a breakdown for the first time I brought this wireless column. But, after a few months later, it was connected to charging a bad USB cord, after which he jumped, smoking and after that the column stopped turning on.

For a start, we take a look, from which "kit" is collected by our fearing handicraft. The bluetooth column disassets easily. First removes the decorative and protective casing.

All major electronics are mounted on a small board, which connects to the keypad, speakers, as well as a power source - 18650 lithium battery.

On the main board only a few chips. Chip AC1720AP11057-5A8. - These are brains of the device (microcontroller), which is built into a Bluetooth module. On the printed circuit board in the form of a broken line resembling meander, an antenna is performed.

If suddenly it happened that the microcontroller was failed, then the fee can be partially or completely replaced by an AC17xxap chip-based module, which a huge set is sold to Ali. Here is the link . It should be noted that they all have a different labeling, for example, AC1721AP10242-5A8, AC1716AP10234-5A8, AC1716AP10238-5A8. As I understood, the chips differ only on the support of different versions of Bluetooth (V2.1, V4.0, V4.1, V4.2).

First, we remove it to solder from the contacts of the element, and then, heating one of the sketches of the soldering iron, we remove the non-working transistor to the tweezers. Since the SOT-23 case is miniature, it quickly warms up with the conclusions. This makes it easier to disassemble the transistor.

After replaced by the burnt Mosfet Si2301 on AO3407, began to check the operation of the wireless column. At first it turned on and turned off, it was connected to the smartphone without any problems, losing tracks. But after a pair, the turn on / off again stopped turning on.

The most interesting thing was that when closing the conclusions of the stock source of the AO3407 transistor, the column was generally turned on and worked even after I cleaned the tweezers - blurred the conclusions of the drain and source. With the shutdown, there was also no problems, by pressing the "POWER" button, the column turned off.

While it was understood what the case was, noticed a cracked diode D2 with the S4 marking on the keypad board.

It is worth noting that the S4 marking is applied to different models of SMD diodes and easily confuse them. But, after quite a long search, I came to the conclusion that it is a SD103AW SD103AW Diode. It is sufficiently low, it has small sizes (SOD-123 / SOD-323 housing). Apparently applied in signaling circuits, has a small voltage drop on the transition (Low Forward Voltage Drop). I met such diodes on printed circuit boards from portable MP3 players.

From the fluidized analysis of circuitry, the following logic of the operation of the scheme has been lined up when turned on.

Let me remind you:

P-channel mosfet transistors open a minus on the gate;

The semiconductor diode has one-sided conductivity.

This will be enough to understand the operation of the inclusion and off scheme. For clarity, I was not too lazy and granked a simple scheme.

When you press the "POWER" button, the MOSFET-transistor q2 shutter (AO3407, native Si2301) connects to minus via diode D2 and opens. Through the opened transistor Q2, the supply voltage is supplied to the entire electronic part of the circuit. The microcontroller opens the bipolar transistor Q1 (marked J6., He is S9014), the collector of which is connected to the bracket Q2. Thus, even after the "Power" button is open, the Mosfet-transistor Q2 remains open and supplies power to the scheme.

DO2 diode, apparently, prevents the circuit with the output of the collector of the transistor Q1 for minus when we re-press the "POWER" button. Since Q1 is open and tested to the valve Q2, then in this mode diode D2 is turned on in the opposite direction and does not skip the current.

Turning off the wireless column is repeatedly pressing the "POWER" button. When it is pressed, the overall wire (it is minus) is connected via D4 diode with a bus control bus. So the microcontroller understands that the signal came off and closes the transistor Q1, and with it Q2. Completes its work.

I think now it is clear why, when closing the conclusions, the source-drain from the AO3407 transistor, the column turned on and continued to operate even when the conclusions are broken. The shutdown circuit was good and therefore the column normally turned off by pressing the "POWER" button.

Since the AO3407 transistor is more powerful than the native Si2301 and differs according to the characteristics, then the capacity of its shutter is also more. And once the shutter capacity is greater, then the charge current of this container when applying for a minus shutter, also more.

And, as we have already found out, the AO3407 shutter is connected with a minus through the button and diode D2. At the same time, a rather powerful charge current of the shutter capacitance flows through the dode D2. It is because of the fact that it is greater than in the case of the native Si2301, the diode D2 was simply burned due to exceeding the nominal current I F, which, judging by the documentation, is only 350 mA (for SD103AW).

To restore the correct switching on the column instead of the SD103AW diode was installed more powerful Diode Schottky B5819WS (marked SL.), which withstands the direct current (I f) in 1a. Its housing is the same as SD103AW. He took it from the board from the DVR.

After his replacement, the bluetooth column began to work as it should and no diodes no longer "crashed."

On this, my long story about the repair of the wireless column is complete. But, I would like to add it. It is no secret that the wireless speakers often fail the speakers. The reason is simple and associated with their intensive operation at the maximum volume.

Most often, such a parables suffer from the same cheap bluetooth columns, the power of the speakers of which is small and is a maximum of 2-3W. The original columns also do not bypass this trouble. Unlike cheap devices, more qualitative dynamics of which are 5-15W in them.

The portable and bluetooth columns are usually embedded with miniature speakers by 1.5-3 inches (inch). The replacement of the native can be found on Aliexpress, for example, in Aiyimatechnology, Aiyimaaudio and Ghxamp. Shops Verified, have good reviews. We select the speaker in power and sizes. If you wish here, you can find a worthy replacement of original speakers from BEATS, JBL, Sony, Philips, smart columns of Google Home.

Visitor reviews about JBL Charge 3 Black

The most frequent question from customers:

Hello! Please tell me why prices are in your store lower than in the rest and sometimes even much lower?

Hello! If I order a column to the Sakhalin region (Kuril district), then at a decision will cost me? If you can all the amount together

Alexander:

Excellent column. I first did not believe that it could play outside. Very convenient in circulation. Turn on Bluetootch and the music was poured. In Pleere only original products. In other places, many Chinese fakes are 2-3 thousand. These are two big differences. As always quickly brought, in a specified period. Recommend.

Hello! And if the column is omitted into the water, then it will hide water or will it work well?

Reply from the forum: Hello! Although in the description and the full moisture protection is indicated, we categorically do not advise you to omit any technique into water, because at best the technique will fail. Thank you for understanding!

Vladimir:

Good day! There is no complaints to the column, it is gorgeous! The only drawback identified by me is when you lose the sound with the Samsung Galaxy S3 / 5, then after some time the sound can be lost on the column, the phone will be shown on the phone that the music is played. To come back the sound, you need to unlock the phone every time and restart the track, then the sound appears again. In the network they write that it can be from the difference in the Bluetooth version, but I doubt it all works with a laptop without complaints, and there is 4.0, Also they write that there is no such problem with apples. In general, the column is very good, especially if you watch movies from the laptop at home and you want to feel yourself in the cinema. Purchased on Saturday, sat only on Thursday. 20 hours, it is probably with complete power without stopping.

Vladimir:

Stunning sound and work hours.

It is written to make moisture protection, and this is actually only moisture protection, or as stated, the water-permeability according to IP7 and is it original?

Reply from the forum: Hello! Yes, the original column and has the appropriate certification.

Column satisfied, playing well, powerfully plays, everything is super!

Great column! The sound pleased! I advise!

I ordered my son this column. Before that I read and looked a bunch of video reviews and articles on the topic: how to distinguish the fake from the original. As a result, the son is delighted :-). I have a musician musician. And in a basin with water, they lived, and fireworks with water splashes arranged. Thanks to store staff. Did not disappointed. P.S. Brought on the day placement of the order.

and how to connect bluetooth and still there you can listen to music from the flash drive

Reply from the forum: Hello! Bluetooth connection is connected standard. You need to select a column in the form of a sound source in the list of connections. The USB flash drive cannot be connected.

I bought the JBL Charge 3 Black in the online store site column satisfied, you should not expect from two small speakers of deep bass and powerful sound, but in general it sounds very decent, and better competitors (personally listened and compared) the battery is just excellent, after purchase it did not charge I decided to discharge completely, it took hours 14. The quality of performance at a high level. Ordered the original case to keep the device in primeval form. I thought I would only take a visit and in nature, as a result I listen to the house almost every day. I recommend buying to buying unequivocally. And the price is now quite adequate.

Novikov Evgeny Evgenievich:

Thank you Team Site column JBL Charge 3 Black I really liked, high-quality and pleasant to the Neckup thing. The battery holds a charge for a long time, playing loudly, the sound is pleasant. Purchase is very pleased.

Cool column Like strong bass.

Tamarok Vitaly Valerevich:

Column Original, Flying Excellent

Everything came on time, a very positive courier caught. All in came on time, the quality of the column itself is excellent. Thank you, I will continue to order here

Louder, husty, protected

Of all the Lines of Portable Acoustics, the JBL of the average buyer is likely to attract the Charge. Against the background of the dubious advantages of the other series, like light summers or carbines, the trump card JBL Charge looks more practical - this is a large battery that can be used to charge other devices. Earlier this year, JBL introduced CHARGE 3 - the fourth model in the ruler. We will tell about it in more detail.

What's in the box?

Equipment for JBL Charge 3 is the same as in Charge 2 - a bright orange power supply (5 V; 2.3 A) with replaceable forks and a Micro-USB cable. Thanks to the protection of the IPX7 class, the need for a case completely disappeared

Design

Previous models JBL Charge had similarity with beer banks. Charge 3 looks like the younger modification of the "Barrel" JBL Xtreme.

In addition to the above color, the column is released in black, gray, red and blue. Although on the official site it is indicated that we got a modification of Teal, in fact the color exactly-in-point turquoise - Turquoise.

In the center of the column case, the JBL logo is highlighted, downstairs the five-perction indicator of charging, bright and very convenient. Even if you look at the top, you can understand the level of charge on the reflection from the table surface.

All buttons are removed upstairs and symmetrically arranged. From left to right: pairing via Bluetooth, loudness reduction, inclusion, installation of the JBL Connect connection, increasing the volume and suspension of the track.

All connectors are tightly closed with a massive insulating plug. If she carefully use it, it is unlikely to begin to leak over time.

The set of connectors is the same as in JBL Charge 2 - output 3.5 mm TRS, Micro-USB for charging the speaker, USB port (5 V, 2 A) to charge other devices. Note that JBL will not bother on the weekend amps in the Charge columns, which can not but rejoice

With the ends in the recesses, as before, passive radiators are placed. As far as we managed to consider, they can not miss the water.

For completeness, take a look at the column below. The base has a small area and embossed texture. Given the solid weight of the column, it is not worthwhile for stability.

In addition to the charge indicator, Charge 3 highlights the power button: blue when pairing via Bluetooth and just white in the on state. The JBL Connect button next is also lit white when working mode.

JBL Charge 3 design really managed. Beautiful symmetric case, interesting textile coating and lack of dubious design solutions like sensory buttons. It is not surprising that some other JBL speakers are very similar to this. The manufacturer will have to very try to make something even more interesting in the next generations of portable speakers.

Measurements

We carried out measurements of the ACH acoustic system on the axis of the main speakers.

Almost all length, the schedule retains an acceptable deviation, going around without extensive failures and peaks. In the claimed frequency range, the lower boundary is surprisingly coincided - 65 Hz. But from the opposite side, the level is over -6 dB much earlier than the declared 20 kHz.

Now according to the method described in the JBL Charge 2 review, we estimate the sound pressure.

The transition to 10-watt speakers did not leave our measuring microphone indifferent. The numbers show that even Sound Blaster Roar 2 with a reinforcing mode does not withstand competition. Standing, however, quite slightly.

Sound

From the time of JBL Charge 2, the sound became more balanced. It is noticeable if you pay attention to the place of vocal in the compositions: many other speakers it dominates, while JBL Charge 3 sounds in harmony with the rest of the ensemble. At the site of the accents of the barrels, the attack of strings, the ringing of Kowbollov. Prophured series Openness The sound did not go anywhere - it is not necessary to churl with the installation, the main speakers look strictly ahead.

We had the opportunity to play with JBL Charge 3 different connection schemes. First we connected the column through the cable with the output of the E-MU 0404 USB audio file, which played the FLAC song from the computer. Then we connected the column via Bluetooth to Huawei Nova Plus and passed on acoustics the same tracks from the Deezer streaming service in the so-called "high" quality whose characteristics are not specified.

According to the results of the comparison, the conclusion is: it is not necessary to hide from portable audio systems, which "only home video from VKontakte voiced." With a different connection, the sound differed dramatically. With a bluetooth connection, the tower strokes almost disappeared, the vocal parties began to confidently join the rest of the "porridge". With a better path of business, there were much better. If JBL Charge 3 form factor systems fit perfectly into close concrete boxes, then why not try to use them in stationary scenarios? Perhaps you will be enough and this, and you can use the saved space with more benefits.

JBL CHARGE 3 implements JBL Connect mode, with which you can synchronize several JBL columns. Works all the same as we described in the JBL Pulse 2 review - through the JBL Connect application. In addition, JBL Charge 3 can work as a wireless headset, and there is nothing unusual in the implementation of this regime.

Autonomous work

As usual, we measured the battery life when connected via Bluetooth. 40 minutes before the marked term of JBL Charge 3 turned off. Apparently, in an attempt to keep the balance residues. But the disco should continue, and we squeezed from the column something else.

Compared to the second version, the battery life has decreased, and the charging time has grown. It's nice that the device does not interrupt music messages about a low battery level, but only flashes the red charge indicator.

conclusions

JBL continues to confidently lead a series of Charge to perfection. It is commendable that the priority remains the quality of sound and design. A bright distinctive feature of Charge 3 is the high class of protection against moisture. By the amount of all the advantages, we get a universal portable device: in the summer it is ready for adventures on the beach, and in the winter - to parties in large living rooms.

At the time of writing, JBL Charge 3 is 2-3 thousand more expensive than JBL Charge 2+. Additional costs here will be fully justified: Charge 3 looks better in everything, except the battery life.

Wireless acoustics JBL Charge 3 will help you feel this freedom. You can use it at any convenient place thanks to the compact dimensions and the capacious battery. The impeccable clarity of the sound and saturated bass will give the true pleasure of music in the beloved genre. By purchasing JBL Charge 3, you will receive a powerful stereo emitter and an energy source in one device.
