Greetings to all lovers of acoustics. On the channel you will find acoustic projects of different power and complexity. Support the channel with a subscription. All pleasant viewing. Приветствую всех любителей акустики. На канале вы найдете проекты акустики разной мощности и сложности. Поддержите канал подпиской. Всем приятного просмотра.
The channel description contains an email for communication, write to me with a subject mark, I can send you the file in CorelDraw. I don't do 3D projections.
मेरी कई परियोजनाएँ चालू हुईं, लेकिन मेरे क्षेत्र में। आप वीडियो के नीचे विवरण में घटकों के लिंक से अनुमानित कीमत की गणना कर सकते हैं, लेकिन मेरे क्षेत्र के बाहर तैयार स्पीकर बेचने का कोई मतलब नहीं है, क्योंकि डिलीवरी बहुत महंगी होगी। आपके लिए अपने निवास क्षेत्र में खरीदना या बनाना आसान होगा।
Bro this thing looks just awesome !! Respect! I want to build a speaker for myself, i have a small canton subwoofer like 8" and a jbl 12" subwoofer i dont need anymore. I dont want a speaker that is impossible to carry arround but i guess a little sub is not good for outdoor use. Second pepblem is that i dont know if a closed design is any good for outdoor use. The tpa3116 is not that powerfull for longhub or too big driver i guess. Third problem, i dont know any parameters like qts for building an enclosure. Or should i buy an 10" car audio woofer which i know the parameters to build a good enclosure ? Like audio system CO 08 evo ? I hope u can help me
To assemble a Bluetooth speaker using a 12" subwoofer, it will be heavy in any case, especially if the speaker requires a large internal volume. For example, on my RU-vid channel there is a speaker with a jbl 12" subwoofer, it weighs about 42 kg. this is a lot, you need to carry it in 2 and carry it only in the trunk of a car. For a portable one, I think the maximum size is 8", as for the power of the tpa3116, it approximately needs an 8" subwoofer, they are usually about 100w. Car subwoofers require more power around 200w and above, you can consider tpa3255. About the speaker parameters, I agree that it will be easier to assemble, knowing the parameters, you will be able to understand what internal volume is needed for the speaker, what design is suitable.
For the best efficiency of designing your Bluetooth speaker in an open environment: a closed box, a bass reflex or with a passive radiator, you will need to at least measure the impedance of the speaker in the box. Based on the result, you can understand what type of design is better suited; if it’s a bass reflex, then it’s better to bring the port forward. A closed box will play well if you buy a good speaker with low FS, a good magnetic system (full quality factor), with a small internal equivalent volume, then you can get low tuning in small dimensions.
If you use CO 08 Evo, it has fs 41.9Hz, Vas 20.7 liters. Let’s assume you assembled a closed box, square, then it will be approximately 28 x 28 x 28 cm, this is inside the case, taking into account the small volume displaced by the speaker itself, i.e. you take into account the thickness of the material and can imagine the future size of the speaker, or rather the compartment for the subwoofer. In this case the resonance will rise to 58-59hz. This is normal for clear and correct sound; you won’t hear low bass in the open air. The bass reflex can be adjusted to approximately 39-41Hz. Just use the program to see for yourself how long the port will be needed, whether it will fit inside the case or make a port along the wall with a 90-degree turn.
@@DIYAcoustic thanks for your Response ! So do you think its stupid to build with a speaker if you dont have the parameters ? I dont want to throw them away or build cases i cant reuse for anything u know. I dont need ultra low bass, 50hz and above would be fair enough
Of course, you can assemble without parameters, but the result can be very bad, for example, you assemble a case, and the VAS dynamics are very large, in the end you will get a very high setting, etc. Of course, it may be that you get a good result the first time, in fact, you can configure it after assembly if you make a bass reflex port using a port in the form of a sewer or some other pipe, selecting different lengths by ear, or use a smartphone microphone in a spectrum analyzer application.
It’s better for you to assemble a Bluetooth speaker or buy it yourself in your region, it will be much cheaper. I sell my finished projects only in my region.
Brother....If you dont mind on stupid question.... approx. All together, what's the ratio of working hours and money that you spend.... Btw.Great job 🤜🏻🤛🏻
All work on the channel was done out of personal interest in audio systems, it’s like a hobby. A lot of time is spent on producing a finished project. For a person who just wants to make acoustics with his own hands, there is no particular point in assembling it himself, since it requires a lot of tools, time, skills, and money for good components, especially if you want to make a beautiful and effective device.
I don’t sell bluetooth speakers, I only make them to order in my region, because they are more expensive than factory ones. If you want something similar in design, you can contact a specialist in your region. You can find out the price approximately by counting the components you need.
Everything is simple, the source is a 6s battery, a 25V charger, 24V is supplied to the amplifier, about 16V goes to the panel backlight through a step-down converter.
Tôi không hiểu ý bạn lắm vì người dịch, nhưng trong bản sao của tôi, loa tần số cao được kết nối với kênh 1, loa tầm trung được kết nối với kênh 2, bảng phát trực tuyến được đặt ở chế độ đơn âm.
Hi! I have a question. I have the same amolifier (tpa3316 2*50w + 100w), and I noticed that above 70% it clips. The bass becomes distorted and sounds trash. Did you noticed that on your own speaker? If yes, how can I fix it?
in my assembly the components are suitable for the power of the amplifier and the amplifier itself is powered by a 6s 24v assembly. If your speakers have a rated power lower than the amplifier, then you will have to: 1) use an external sound source module, bt, usb, etc. but with volume control. 2) if there is Bluetooth on the board, then use 2 variable resistors in series, 1 will be a volume limiter, 2 will be external to control the main volume.
Eu sei que vice estar fazendo vídeo pra intertenimento.! Mais assim. A minha pergunta? E você fosse vender essa caixinha pra uma pessoa. Ou alguém a quise-se a comprar. Por quanto você venderia, a caixinha,???
Coleciono projetos principalmente por encomenda ou para pessoas que conheço. Se você quiser comprar algo parecido, então você precisa escolher na sua região, a entrega do meu país vai ficar muito cara e a embalagem pode ficar danificada. A única coisa que posso te ajudar são as dimensões, tem um desenho em Corel, mas usei um alto-falante médio do microlab h600, você simplesmente não pode comprar isso, então ainda terá que mudar alguma coisa ou usar outra coisa .
Нафига вы самоделкины повышайки ставите? что нормальный аккумулятор лень собрать!!! да ещё на токую мощность такой сикошный аккумулятор поставил! он от силы 30 минут поиграет в пол мощности!
Потому что проще и дешевле 3S собрать, чем 13/14S. Проще : контроллер с балансировкой, мин кол-во банок меньше, распространенные ЗУ на 12в. и тд. Это не самокат, а колонка, к тому же по сути стационарная, так как тяжёлая.
I think it’s better and easier and cheaper for you to make a similar Bluetooth speaker in your country. If you need the dimensions of the parts, I can send you the file by email, write to me, in the channel description there is an email for communication, only you will take into account your speaker sizes, mounting for the amplifier and more.
