Your speaker is made of two things: an amplifier that takes an audio signal and makes it really loud and an exciter that creates sound by vibrating. Lay everything out on the table. Something missing? It can take up to 10 minutes for your iron to heat up.
If you get burnt, put your finger in cold water for 10 minutes. Tie long hair back to keep it out of the way. Use goggles to protect your eyes. Wet your sponge. Ignore this step if your soldering iron does not have a sponge. Hold your iron like a pencil. When you're done using it, put it back in the cradle. Find the hottest side of your iron by melting a little bit of solder. Try rotating it until you find the hottest part.Global cainiao customer service
When you connect components into them with solder, electrical connections are made. Find the diodes. A diode is a component that allows current to flow in just one direction. The diodes have a black stripe on one end, to show the negative leg. This asymmetry means they have polarity and must be placed in the circuit the correct way. If you can't find them, they're in the bag labelled 'Resistors'. Bend the legs into a 'U' shape. Use a flat hard surface like a desk or table to bend the legs against.
This will give you a nice crisp corner. Place on the PCB. Polarity Alert! Double check that the black bands on your diode match the ones on the PCB or your circuit will not work. Flip the PCB and secure with tac.
The tac stops the PCB from moving around while soldering.He has worked on this extensively and is a treasure trove of good info. I since have discovered that you can really do some cool things with them by playing with driver placement, cutouts, adding mass, adding felt, adding ribs, making them huge, making them multi-way FAST, etc.
There are several very large threads on this on the web. It might be tough for a newbie to comb through. I am a newbie at this so thought I would document my journey for the Full Range forum to follow. I think it really could be a great full range speaker with some careful experiments. One can play with shapes, cutouts, mass loading, variation in thickness and materials, boundary clamping conditions, etc.
The idea is to spread the modes evenly with not any one mode dominating and causing a spike. First thing is to play with it to get a feel of what we are dealing with. What is nice is that it is relatively cheap to play with. Foam core or corrugated cardboard doped with shellac or PVA seems to be the materials of choice. Some interesting facts: 1. Although it has no baffle, it is not an open baffle OB dipole in behavior - that is, there is no huge bass rolloff and it hits surprisingly low 40 to 50Hz is easy for a zero baffle driver.
It is not a dipole but behaves more like a bipole or an omni. It has very quick snappy transient response - nice drum sounds.
It is sensitive to how you mount it or frame it or hold it.Write 8085 program to generate a delay of 1 second
You are building a driver in reality - a driver and zero enclosure. You want to avoid symmetric shapes and symmetric exciter placement in order to reduce the effects of the main symmetric transverse drum head eignmodes.
Think reflection anti-symmetric shapes like uneven trapezoids, pentagons, blobs, etc. It operates more by having high velocities and large areas for good efficiency vs large displacements - thus small drivers and large panels can be surprisingly loud.Show 20 Show 40 Show 60 Show 80 Show All times are GMT.

This site is dedicated to all the loudspeaker DIY enthusiast searching for high quality DIY loudspeaker designs and information about building loudspeakers including driver unit measurements etc.
By building DIY loudspeakers you have the possibility to adjust the loudspeaker to your own preferences and sound ideals.Making an audio exciter speaker pt 2
Several of the loudspeaker models presented on this web site will have different tuning options in order to offer a wider DIY public a chance to find something that matches their personal taste and preferences.
That could be e. In my personal experience, building your own loudspeaker cabinets can often be as expensive as buying commercial cabinets. Sometimes it can be much more expensive depending of the choice of finishing. AudioExcite has the goal to offer DIY loudspeakers designs that fits into a normal sized listening or living-room and to present more detailed measurements than usually found in other similar web sites.
The web site will grow over time and new loudspeaker series and models and driver unit measurements will be launched as time flies. For further reading about Audioexcite go to the Who is? I hope you enjoy the reading on this web site and be sure to follow my projects on my Blog!
Design Philosophy:. To me, designing a loudspeaker is like cooking a fancy dinner. Let the fine ingredients speak for them self.How to get proof of funds letter from bank of america
The same thing goes for designing cross-overs. Keep the number of cross-over components to a minimum. It will sound better. Instead look back and see if you have chosen the right driver unit for the design. Other important factors for a successful design is to achieve an even power response and off-axis dispersion as well as a satisfying distortion behavior for the loudspeaker.
The choice of driver units for a design is an important factor for a successfully implemented design. The driver units here are carefully chosen from a variety of loudspeaker driver manufacturers. These cabinets are affordable and beautifully built cabinets and is available in several different finishes, like gloss black, cherry and maple.
These enclosures are available in both curved cabinets as well as conventional square boxes. Here is how Dayton Audio describes the enclosures:. Dayton Audio pre-made enclosures eliminate the time-consuming and messy steps of cutting wood, assembling the panels and bracing, gluing veneer, and finishing.
Using speaker cabinets will guarantee superior results every time. The entire cabinet, including the rear, is covered with a piano-quality black lacquer finish that is extremely glossy and reflective. It offers the flexibility of the B-REX replacement system and comes pre-finished without any driver cutouts. The grill is secured to the baffle by neo magnets in line with the machine screws that fasten the baffle to the enclosure.
Attractive curved-sided design is extremely rigid and solid, with minimized panel resonance. Complete with baffles, hardware, and grills. Add crossover parts, port tubes, damping materials, binding posts, and your drivers to create a complete system rivaling the appearance of the most lavishly presented audiophile speakers. I can say it right away! In all of the AudioExcite loudspeakers I use cross-over caps and resistors from Mundorf. Mundorf describes the Mcap Audiophile cap as follows:.
This cap gives a bit more refinement in the upper frequencies and the higher price tag is motivated by the additional performance improvement.

Mundorf describes the Mcap Supreme cap as follows:. All of the AudioExcite loudspeaker models uses air-core coils as standard. Where very large coils are needed, iron-core coils are used. Mundorf describes the foil coils as follows:.Found several youtube posts re flat panels styrofoam, balsa, wallboard, etc used with "exciter speakers. No clue about the sound though. Anyone experimented with these? OK; here's another one. Last one. Funny enough I came across a guy at a trade show I was doing a few years ago who was selling something similar but less sophisticated.
He was shooting for the camping backyard party market and tied to a cell phone or IPod type device. I looked into these quite a bit a while back but never pulled the trigger on getting the components. From what I read they will make excellent surround or ceiling atmos speakers and they radiate in a way that nomatter what angle you listen you still get a good soundstage. Many people rum them with a super tweeter though for the high end.
I think the optimal setup is using rigid fiberglass board. The technology is actually moving into the pro audio field as well:. Companies are selling hidden speakers this way. The speakers can be items you wouldn't typically think about like pictures on the wall or other items.
I would love to hear a pair of the tectonic panels in a medium sized p. I can see awesome possibilities. Haha, maybe I'll try a graphene sheet. The Honda Ridgeline "pickup truck" uses exciter speakers in the truck's bed panels so the entire bed is made into a tailgate speaker.
Wondering if the old man would flash a button on these guys. OK; will order some tactile speakers from PartsExpress and "play" with cheap boards before I spend big money. New tech and he was an engineer We already have those here on the West Coast. The Subsonic Subduction unit needs some more damping, though. We've thought of pouring glue into it. OK; ordered some exciters from PartsExpress and carbon fiber from another place You can post now and register later.
