    Beautiful build. Is there any particular reason to WHY you didn't shoot for a higher RMS powered amp and drivers as well as battery. I'm also curious as to how long it holds a charge under moderate listening conditions? ? ?

    • @SoundBlab
      @SoundBlab  7 ปีที่แล้ว +1

      Thanks. The bluetooth amps I could find that has higher output normally requires a higher power voltage than the 5Volts I was after so that it can be charged via USB. Also, the 10 watts this speaker for it's size produce seems to be adequate for my needs. I use this speaker everyday with my laptop for a couple of hours and only need to recharge it once week or two. Probably at slightly lower than moderate listening levels though.

    hi great job it looks amazing. But from what I understand from that specific passive radiator, it should be mounted, the other way, so that the grooves are invert:). i haven't tested it yet, so I am not sure

    • @SoundBlab
      @SoundBlab  7 ปีที่แล้ว +2

      Thanks Amir. I have not tested it either, but it really should not make a difference in the performance. There are many drivers and passive radiators out there with inverted surrounds.

  • @blazemathews
    @blazemathews 6 ปีที่แล้ว

    I built a Bluetooth Speaker with a 2 3w 4ohm speaker powered by a PAM8403 amplifier supported by 5v 1A powerbank charger module and for the bluetooth i have used a USB powered bluetooth adapter
    Now while connecting 5v output from the powerbank module is connected to the +ve and -ve of the amplifier module and the same wire I removed the sheath connected a B0505s-1w dc -dc 5v-5v isolating converter to the respective +ve and-ve wires and the output from the converter to the Bluetooth Module
    Problem1: Ground Loop Sound Interference still exist
    Problem2: Slight heart beat like thumps from the speaker
    Can you help me find a solution to this?
    Thanks in advance

    Hi if i may be so bold for the people who dont like the starting noise you can put a switch inline with each speaker positive and turn them off before powering the device on then wait till your connected and switch them back on although i dont personaly mind the startup sound its something i got used to hope this helps and also great video love this build #soundblab

    Besides the wood glue which glue are you using? For example when you glued the cloth to the wood. Thank you!

    • @SoundBlab
      @SoundBlab  6 ปีที่แล้ว

      That is contact adhesive. I apply it to the wood, sometimes 2 layers and then wait until it starts to get tacky. I then stretch the fabric over.

  • @Sqeezerful
    @Sqeezerful 6 ปีที่แล้ว

    Excellent build, particularly on the audio and mechanical side. I would advise to use a LiPo pack that has some protection build in. A flat pack would also be easier to mount securely in contrast to the 18650 round cell and help avoiding unprotected wire links.
    When soldering directly to round cells, a low temp solder e.g. Sn42Bi58 would work great complemented by a low temp setting on the iron would help. In general I’d use more insulation, in case some glue breaks and components come lose and rattle around in the enclosure.
    From an electrical design standpoint step up booster are something I’d try to avoid in an audio context as they are prone to introduce noise to the power rail. I’d investigate towards an amplifier that works well with 3.2V (lower discharge level of the LiPo). If that isn’t feasible - a look into higher battery voltages e.g. 7.2V might be helpful with either a step up charge when USB compatibility is crucial or an external plug pack with a higher voltage might be useful to feed a 7.2V battery.
    I’d suggest some kind of indicator that the systems is “running”. An extra LED shining through the front cloth might be nice.

    • @Sqeezerful
      @Sqeezerful 6 ปีที่แล้ว

      E.g. 3.7V flat pack battery w. protection:

    Do you buy speaker drivers locally, and if so, where if you don't mind me asking? That's if you buy from local suppliers. Only place I found with reasonable choice is RS Components. I've been wanting to build a pair (maybe with a 3rd woofer box) of full range desktop speakers for some time now.

    • @SoundBlab
      @SoundBlab  7 ปีที่แล้ว +1

      I have bought from RS before, but the choice is limited. I mostly buy from eBay, Madisound, or Parts Express, which means we pay a bit of a premium when you consider the high shipping cost.

    About the anti pop capacitor, what value do you use, and how did you calculate it please ?

    • @SoundBlab
      @SoundBlab  7 ปีที่แล้ว +1

      Thanks. The capacitor is a 10V 1500uF. As long as the capacitor voltage rating is higher than the input voltage you should be fine. You want a capacitor that can give you a longer 'charging/discharging' period. For this you need a relative high capacity such as the 1500uF I am using.

    Another excellent Video SoundBlab, thank you! Really like how you make the vids in general, with the fitting music to make it almost a chillout session and not some effed up dub/metalstep... I you allow, a little question; using it at let´s say 50%-75% volume, what is your guess how long the battery will last? I guess adding another one could help, but if you say it lasts for 4 Hours (what I somewhat doubt) it should be okay...

    • @SoundBlab
      @SoundBlab  7 ปีที่แล้ว +1

      Thanks man, glad you are enjoying the videos! I have not done a test to find out how long the battery will last, but I use it almost everyday for an hour or so at moderate volume (20-30%) and I only have to charge it every week or two.

  • @MrFreakwent

    • @SoundBlab
      @SoundBlab  6 ปีที่แล้ว +1

      Thanks man, appreciate the support! You can go to this URL (led.linear1.org/1led.wiz) and calculate the values for the LED/Resistor circuit that you can connect across the positive and negative output terminals coming from the step up power booster board. The same spot where you connect the capacitor. Enter the values as follows for a red 5 Volt LED: 6.5 and 2 and 20. You should get a resistor value of 270 ohms. I have not tried this in my own design, so you do this at your own risk. However, it should work if connected up correctly.

    @david199782 7 ปีที่แล้ว

    hello, considering that there is a 5 watt apmplifier pushing power to 15 watt speakers there is probably distortion on high volume or am i mistaking?

    • @SoundBlab
      @SoundBlab  7 ปีที่แล้ว

      This is a surprisingly good amplifier module and there is almost no distortion at the higher volume spectrum. If there is any it would more likely be the quality of the speaker connected to it and whether it has a flat frequency response or not. When the FQ response is not flat, the accentuated frequencies will sound like it is distorting. The speakers I specified for this build has a good flat response and sounds balanced all the way to the top.

    • @SoundBlab
      @SoundBlab  7 ปีที่แล้ว

      Of course, because this is a small speaker and the bass output is limited as a result, 'balanced' in this case is relevant to this fact.

    Dagsê.. What is that square piece called that you insert in the front between the speakers? I have seen you use round ones as well. Is this purely for cosmetics or does it add to the sound characteristics?

    • @SoundBlab
      @SoundBlab  4 ปีที่แล้ว

      It is called a passive radiator. Essentially it replaces a typical port in a speaker and acts in the same way where it is tuned to a specific resonance frequency that determines the bass output of the speaker enclosure. The advantage over a port, is that it can reduce the typical boomy sound of a port and reduce port noise as the air flows through a port (in a nutshell, the science is more involved, but hopefully this explains it somewhat).

      @hendrikvanlamp5167 4 ปีที่แล้ว

      @@SoundBlab that explains it perfectly, thanks so much for taking the time to explain it.. Much appreciated. I thought it might have something to do with SPL because there is no port etc.. So it can "Flex" 😂

  • @msicklanka2839
    @msicklanka2839 3 ปีที่แล้ว

    Super work. Was the box sealed properly, with speaker mesh comes between wood. I would add speaker mesh last. Also I think two passive radiators will do better one at the front and another at the back. That Bluetooth module is good (CSR chip only) but in built amplifier is not enough. it is for headphones. better to use a separate amplifier module. Also I would prefer passive radiator with a metal frame as the way you applied glue could affect its movement.

    • @SoundBlab
      @SoundBlab  3 ปีที่แล้ว

      Thanks. I do agree that a second PR could benefit the design, but everything else works very well. Well sealed enclosure, PR moved correctly and is still working fine after few years. And it goes loud for the size, definitely not an amp suited to headphones. You will blow them up.

      It is a nitrocellulose based sanding sealer with very good grain filling and sanding properties. It is used for grain filling on interior woods and when sanded gives a very smooth finish. It works well to seal MDF wood before applying an undercoat or top coat.

    hello sir
    i want to know all components used in this build.
    i know some. i want to know is it bk8000l Bluetooth module?
    MSB, DRILLING MACHINE.
    what is name of smoothing MACHINE(for corner)? and the name of net used in front of speakers? and the what is black tap for air tight.
    please tell me remaining important.

      All the parts and where to get them is in the video description. Not sure exactly what you mean by MSB, drilling machine and smoothing machine, but the corner scan be rounded with a router, and the drilling is done with a drill stand and cordless drill.

    Why are you filling in cotton ?
    I built the same one ( with a passive radiator on the back as well), but the passives won't vibrate. Any tips ?

    • @SoundBlab
      @SoundBlab  7 ปีที่แล้ว

      It is Poly-fill or Dacron. It is used inside the speaker enclosure to provide dampening to the drivers and assist in minimizing standing waves inside the enclosure. It is important not to overfill the enclosure, you want to use only the right amount of fill, to much and the speaker can sound dull.
      The passive radiators must be match to the drivers you use. If it is too heavy the passives will not be able to resonate at an optimum frequency. If the passives are lighter in weight it can move more and will work at a more optimum frequency.
      The rule of thumb is that the passive must be around 1.5 times the size of the effective radiating area of the driver. However, that is only half of it, you must also determine the ideal weight of the passive from the tuning frequency of the enclosure with the driver you used.
      So, just use a passive that is lighter in weight.

    silicone or edge rubber thinner so you do not have sound leakage.

    Why do you use a capacitor and what kind is it?

    • @SoundBlab
      @SoundBlab  7 ปีที่แล้ว +5

      The capacitor helps to reduce the typical 'pop' sound you here when switching on the speaker. It is a polarized electrolytic cap with a value of 1500-1600uF (16V).

  • @BarryLlewellynYT

    Very cleanly built! Fair play. I would appreciate some credit for the electronics design in the future though.. ;)

    • @SoundBlab
      @SoundBlab  7 ปีที่แล้ว +3

      Hey Barry, Thank you! You are welcome to take credit for it, but for the record your build was not used as reference and no harm was intended in the process! The speaker was not designed and built to be based on any other build and parts were selected through my own research, testing and availability. I went through a few iterations before settling on this particular electronics configuration. With so many similar builds around I think it is easy to put something together that resembles something else and use similar parts without intending to copy someone else's design.

    • @BarryLlewellynperson
      @BarryLlewellynperson 7 ปีที่แล้ว +1

      No harm done :) The electronics configuration here is exactly identical to my previous speaker design however. Also just a quick suggestion, these 3 inch passive radiators would likely be a better alternative to the passive radiator shown above, as it's much lighter and therefor closer to the resonant frequency www.ebay.com/itm/2pcs-3-inch-75MM-Bass-diaphragm-Bass-passive-board-Speaker-Bass-Film-/262915552093?hash=item3d36fcf35d:g:S4YAAOSw4CFYuLAH Looking forward to the future videos! :)

    • @lukaswalczak93
      @lukaswalczak93 7 ปีที่แล้ว

      Barry Llewellyn YT I have built a similar speaker like your one but many months before you uploaded your result. This electronic configuration of a Li Ion Cell combined with a charging module, this popular 5w Bluetooth amp and a Voltage booster, set to the max Voltage of 6.5V ist really common. Just because you uploaded earlier doesnt necisarrily mean that you invented this configuration/schematic. But you also need to give credit to Bose and their design of 2 Woofers and a passive Radiator. I can hardly believe that this also was your idea...
      Cheers

    • @BarryLlewellynperson
      @BarryLlewellynperson 7 ปีที่แล้ว

      The CSR8645 bt+amp board was virtually unheard of at the time when I uploaded my design, compared to now where it's becoming almost as well known as other compact boards like those based on the PAM8403 platform. However of course there is the small chance that both designs could co-exist without either entity being aware of it. Small details, right down to capacitors of the same value and protected 18650 cells made me a little suspicious. As mentioned before no hard feelings, just pointing it out :) As for the second point, Bose were in no way the creators of the 2 woofer 2 passive radiator format for enclosures. The only significant innovation that I can think of in their Soundlink series is there long-throw passive radiator designs, something not featured in either of these designs.

    HELP! I am amazed at your talent making exactly what I am looking for - except as most of you know I am technologically challenged! The speakers in my car only work on the dashboard, which you know sounds nothing better than playing music through a tin can. Can't understand a word. Now, I really am impressed at how you make the speakers that take a simple USB connection; how about one that works through the car cigarette lighter? It can have a longer cord that wraps through the console, but offers a decent interpretation of music. By the way what does Bluetooth mean??? I beg your help. This is a new (old) car for me and it seems this model is known (not to me originally!) by Chevrolet, but never recalled. I am counting on my You tubers to make suggestions! I thank you, over and over. Kitty Kelso

    Did you use the capacitor because you were using an unprotected charger?

    • @SoundBlab
      @SoundBlab  7 ปีที่แล้ว +1

      Thanks. No, in this case the capacitor helps to prevent a pop sound when you switch on the speaker. It's needed for both un- and protected charger boards.

      Oh ok! And how do I know which voltage and uf of a capacitor to choose?

    • @SoundBlab
      @SoundBlab  6 ปีที่แล้ว +4

      Always make sure that the voltage rating of the capacitor is higher than the supply voltage for the application. If you are using a 12 volt supply, then make sure you use a capacitor that is rated 25 volt, for example. For a 5 volt supply use a 10 volt cap. Also make sure the cap is of the polarized electrolytic kind with a positive and negative lead. Connect the cap in parallel with the output of the power supply rails with positive lead to the + rail and the negative to the - rail. Use a cap with a value of about 1500 or 1600 uF. However, I am not an electronic engineer and can only tell you that this has worked for me when I have used designs that is powered with a battery that is connected on a charging circuit at low DC voltages. I have not tried this in any other configuration. Perhaps there is a more knowledgeable person around here that can comment on this and how it works?

    u need another passive radiators -1 passive radiator should be 1.5 x the dimension of 1 driver

    • @SoundBlab
      @SoundBlab  7 ปีที่แล้ว +10

      That is a general rule of thumb, which I agree with in principle for builds using larger and more easily measurable components (small components are very difficult to measure accurately with basic equipment). However, with small drivers like this with limited excursion and output, in order to make that radiator move, it cannot be too heavy or too big. In this case it works well and I think two radiators would not have made any difference to the result.

    Hey sir, I have a idea! can we make an arduino home assistant? Which means, we make a thing with arduino that takes our voice to our phone and takes the audio that is produced by phone to a speaker via Bluetooth(hc-05).our phone works as the SERVER. when we ask "what is the whether", the mics should pick up our voice and sent it to our phone, then our phone executes it and sents an audio input which is then transferred to our speakers. and in our phone we can use a personal assistant app called alexa. it automatically takes in our commands when we say "HEY ALEXA" without pressing any button or switches. wait but first let me know is it a dumb idea or a good. it will be great if you make a video in that. Like if you agree.....
