The products brought to you this time are the LKER LKS1 portable waterproof bluetooth speaker. The speaker is mainly waterproof 7 degree, 360° sound effect and fashionable and light. There are many Bluetooth speaker products on the market and the competition is fierce. To survive in such a market, a star product is indispensable, and to become a star product, there must be some excels . LKER LKS1 portable waterproof Bluetooth speaker waterproof function is what I value the most. Such a portable Bluetooth speaker can't be avoided in outdoor use. However, some sudden outdoor conditions and weather changes will affect the user experience. The waterproof function is particularly important. Let the author take you to take a good look at this product.
This review, in addition to the regular unpacking, appearance and function display, the author also joined the disassemble. After all, as a product that uses waterproof as a selling point, how many waterproof measures it has in the end and how waterproof effect is definitely a user's concern, so the author has a detailed disassemble introduction, you can simply understand its internal structure.
LKER LKS1 portable waterproof Bluetooth speaker packaging drawer design, materials solid, can be a good protection of internal products.
The internal shock protection foam tightly wrapped the product.
The LKER LKS1 is also fully equipped with accessories. It comes with an AUX cable, a charging cable, a velvet case and a hand strap.
Although there is pleasure in out of the box, there is really nothing to say. What I care about most in this respect is whether the packaging can protect the product and whether the accessory is complete. For example, the AUX cable included here is rarely used by ordinary users. If not, it is estimated that it will be sprayed by many netizens.
LKER LKS1 portable waterproof Bluetooth speaker with colorful design, there are many colors to choose from, the author of this hand is dynamic green.
On both sides of the fuselage design is basically the same, I basically can not tell which side is positive, which side is the opposite. Each side is equipped with two high-performance carbon fiber horns and a passive diaphragm. In total, there are four high-performance carbon fiber horns and two passive diaphragms.
The top of the fuselage is from left to right, hidden NFC module, indicator light, switch button, short press the previous song (long press the volume down) button, short press a song (long press the volume increase) button, play pause Call button and microphone module. The button feels good and the function is good enough.
Side of the fuselage, one side of the AUX interface and Micro USB charging port, the other side of the two openings are used to tie the hand rope. Bound hand straps can be liked, so that when you go out, you can just go out like a radio on a grandfather's knees, squat in your hand, talk about it, and think about it.
In the absence of Bluetooth, users can use AUX to connect with the player, so not only can be used on the phone, but also on the tablet, computer or MP3 and other devices to use this product. Well, this feature is still very practical, after all, many players do not have Bluetooth, with this desktop computer can also be used as a small speaker.
The Bluetooth connection is also very simple. After the phone is switched on, you can directly search for the Bluetooth device named LKS1. This is the LKER LKS1 portable waterproof Bluetooth speaker. Click the link.
As a waterproof bluetooth speaker, LKER LKS1 portable waterproof bluetooth speaker officially claims to have 7 levels of waterproof, which means that this product supports water immersion. I used a step-by-step approach to test the waterproof performance of this product.
The first is the normal splash test. The LKER LKS1 portable waterproof Bluetooth speaker is not under any pressure in this test.
Then the author conducted a bubble test, and the water level probably did not cross the bottom several rows of sound reinforcement holes. LKER LKS1 portable waterproof Bluetooth speaker performance in this test is still no problem, survival confirmation.
In the end, the author used a relatively violent direct flushing test. The author put the LKER LKS1 portable waterproof bluetooth speaker in the pool and used the faucet to flush water directly. The LKER LKS1 portable waterproof Bluetooth speaker still performed well in this test, was able to continue working and survive confirmed.
After the above three steps of testing, it can be basically confirmed that the waterproof level of this product can really reach level 7 waterproof.
The waterproof test is over, and it can work normally, but does the interior get into the water? What is the effect of waterproofing? I decided to disassemble the LKER LKS1 portable waterproof Bluetooth speaker and see if there is water intrusion inside the LKER LKS1 portable waterproof Bluetooth speaker. But first of all to remind you, after the teardown, this Bluetooth speaker's waterproof performance will certainly decline, because many parts of this speaker are sealed and fixed with glue, many operations are irreversible, that is, you can not completely restore the original appearance, So you have to think about preparing for the demolition.
First wipe the appearance clean, remove the rubber protection ring around. This is very simple and straightforward. It's not bad.
Use the wand to directly tilt the front and back panels. It does not use very hard and it is very easy to remove. Another thing to note is that the baffle before and after this is metal, and the force is too fierce to be easily deformed, so be careful and remember carefully.
After removing the front and rear panels, we can see the carbon fiber horn and passive diaphragm. The carbon fiber horns and passive diaphragms are all closely connected with the fuselage, and glued around them to ensure that water does not invade the inside of the fuselage. This is a good job, worthy of praise.
The button part at the top of the fuselage also has waterproof measures. The top of the button is covered with a rubber pad, and the rubber pad and the body contact part are glued to prevent water intrusion. Note that the operation here is irreversible, and if it is removed, the waterproof performance will definitely decline.
Remove the eight screws to separate the front and rear panels. After opening, we can see that there is still some water intruding into the inside of the fuselage, but the volume is not large, not to affect the level of work.
Between the two front and rear panels, rubber strips are used for sealing. This seal must be necessary, otherwise the joint part must be the easiest to enter the water.
The battery is covered with a layer of cotton. According to the author's speculation, this design can absorb the water that invades the inside of the fuselage to a certain extent and protect the battery. But I'm not sure.
To continue dismantling, use tweezers to remove the two plugs that connect to the front and rear speakers. Here is a little slower, tearing the line off.
Then remove the battery plug. In fact, you should take down the battery and check it out. Forget it. It's fine if you pay attention.
Between the battery itself and the motherboard is fixed by glue, you can open it slowly. The battery, the battery body wrapped in a silver bag, the top battery circuit board is also wrapped in a sticker, the only place that may cause a short circuit is the connection to the motherboard.
Use tweezers to remove the microphone module. The glue between the microphone module and the fuselage is also glued and wrapped with a rubber pad. This operation is also irreversible, and it will certainly leak after being demolished.
Remove the motherboard by unscrewing the screws that secure the motherboard.
We can see that there are some water stains on the main board's contact surface with the battery.
The back of the motherboard is also the same as the battery, covering some cotton to absorb moisture and reduce water contact with the motherboard. Most of the electrical components are on the back of the motherboard, but there are not many waterproof measures on the back side. It is recommended to properly cover some plastic protective film on the back of the motherboard.
After removing the motherboard, the entire dismantling work of the LKER LKS1 portable waterproof Bluetooth speaker was completed.
After cleaning the internal water stains, the author was ready to put it back. Here to remind you, if you are ready to put it back, it is recommended to first connect the left and right connectors first, try this speaker is still not good, can not work normally, if not, then find the cause of the deal in time, it is really nothing, then do not bother to go back , throw it directly, but also effort, anyway, put it back to estimate can not be used.
The author first connected the cable and conducted a power test to ensure that the LKER LKS1 portable bluetooth speaker could be reassembled after it was working properly.
Through dismantling, we can clearly see that LKER LKS1 portable waterproof Bluetooth speaker this product, in the waterproof or under a lot of effort. All kinds of seams have protective measures such as glue or rubber pads, and the battery and main board are also accompanied by absorbent cotton. Overall, this product is still good workmanship, waterproof performance is also outstanding, allowing users to use this product in harsh environments. Anyway, when it is raining or taking a bath anyway, it is sure that there is no problem.
