Hey, friends this is a booooom!! box with two different sized speakers why???? for two purposes one for loud listening and other as earphones.It runs on mobile phone! as a headphone it takes power from mobiles' headphone port i took this big speaker out from old telephone set from the receiver it consists of two switches for switching between microphone and loud speaker it weighs 23 grams only! which makes it portable and efficient to use its dimensions are 5 cm * 5 cm * 4 cm which makes it handy too! the other micro speaker is available from ordinary headphones It consumes less power because it runs on the same power as micro speaker power consumption BUT ! THE LOUDNESS IS ENOUGH TO MAKE YOUR EAR BURST. IS IT WONDERFUL HERE'S A VIDEO OF IT WORKING BUT THE SOUND RECORDED IN THIS IS LOWERED I WAS FED UP FROM LAST YEAR BECAUSE NONE INSTRUCTABLE OF MINE WAS GETTING FEATURED SO THIS TIME I WORKED HARD AND CLICKED CLEAR PICTURES FROM MY CAMERA . this can be used in parties , home , and for any type of entertainment as u know that entertainment is a necessary part of our lives and makes us feel fresh and comfortable! let's watch a video of it working!!!!!
Step 1: IDEA OF IT AND DESIGN OF INTERNAL CIRCUITS
I got this idea from the larger versions of boomboxes actually yesterday my sister damaged my headphones so i was annoyed due to this and i kept working late night to repair my headphones and during this i grew a lot of interest in audio systems still i know a little but enough!! I t consists of two speakers with different sound qualities the smaller one for close ear hearing and the larger one for open far away hearing with a loud noise during my late night repair i found that the head phone port cable is also having two terminals which was very useful for me the boombox receives input and electricity from mobile it is having two switches one for loud speaker and other for micro speaker from the one port only you as you see the circuit as shown in first picture its my humble request please vote for it !
Step 2: THINGS REQUIRED
IT COST ME VERY CHEAP MATERIAL I NEED FOR THIS WAS AS FOLLOWING
- LARGE SPEAKER
- SMALL MICRO SPEAKER
- TWO SWITCHES
- MULTI TOOL FOR MAKING HOLE
- BATTERY FOR CHECKING
- AUX CABLE
- SOLDERING IRON
- INSTANT GLUE
- WIRES AND CABLES
- MOBILE PHONE
Step 3: STARTING THE PROJECT
I NEED INSPIRATION AND TIME TO START IT FIRSTLY I MADE SPACE WITH ENOUGH LIGHT AND AIR FOR MY WORKING SO I SIT NEAR THE DOOR I GOT READY WITH ALL MY MATERIAL REQUIRED AND KEEP IN MIND THAT MY PROJECT SHOULD NOT BE IN VAIN BECAUSE A GOOD STARTING IS HALF DONE FIRSTLY I TOOK CARDBOARD AND MARK THE DESIGN THAT IS IN NEXT STEP NEXT I PLUGGED IN MY SOLDERING IRON TO MAKE IT FOR ON THE TIME USE . AND CLEANED MY TOOLS SUCH AS SCISSORS AND CUTTER INCLUDING ARRANGEMENT OF PEN AND PENCIL
Step 4: THE DESIGN
THE BOOMBOX IS ALMOST A CUBE AND IS SURELY A CUBOID IT IS HAVINGVING PORT ON SIDE AND TWO SWITCHES ON ITS OPPOSITE SIDE ON TOP IS THE LOUD SPEAKER AND IN FRONT IS THE MICRO SPEAKER
Step 5: MEASURING AND DESIGNING
Unless we are able to measure some phenomena, we cannot say we scientifically know anything about that thing.
Measurement gives a base to understand the universe. All around us we are surrounded by various things. We might not note it but unconciously we are actually "measuring" things and understanding them one way or the other. Just imagine how a world would be without being able to measure anything. We are surrounded by Measurement.
Step 6: CUTTING PIECES
I MEASURED THAT 5 CM * 5 CM * 4 CM IS SUITABLE FOR MY BOOMBOX First things to get are of course the knives. I have two different knives I do the cutting with, one pen-knife with switchable blades and one snap-blade knife. The next thing is a metallic ruler. Aluminium isn't good as the knives carves it, at least it should have steel reinforcement. My ruler has a straight angle in it, which is also a necessary tool, but on the other hand, it limits the usability if the angle isn't in the level with the rest of the ruler. You should avoid dropping it as it can alter the angle. The next item is a cutting board. It's not necessary, I used layers of cardboard for a long time, but they get worn out pretty quickly. You should ask for those in hobby stores, artist's stores or hardware stores.
Step 7: SWITCHES AND SPEAKER SOLDERING
The first thing you will need is a soldering iron, which is the heat source used to melt solder. Irons of the 15W to 30W range are good for most electronics/printed circuit board work. Anything higher in wattage and you risk damaging either the component or the board. If you intend to solder heavy components and thick wire, then you will want to invest in an iron of higher wattage (40W and above) or one of the large soldering guns. The main difference between an iron and a gun is that an iron is pencil shaped and designed with a pinpoint heat source for precise work, while a gun is in a familiar gun shape with a large high wattage tip heated by flowing electrical current directly through it.For most printed circuit board work, a solder with a diameter of 0.75MM to 1.0MM is desirable. Thicker solder may be used and will allow you to solder larger joints more quickly, but will make soldering small joints difficult and increase the likelihood of creating solder bridges between closely spaced PCB pads. An alloy of 60/40 (60% tin, 40% lead) is used for most electronics work. These days, several lead-free solders are available as well.
Step 8: CIRCUIT JOINING
JOINING CIRCUITS IS A EASY JOB BUT SOMETIMES CAN BE DIFFICULT SO JOIN THE CIRCUITS CAREFULLY AS SHOWN IN EARLIER STEPS YOU CAN USE TAPE SOLDERING IRON ETC.
Step 9: NEED FOR DELICATE HANDLING
Learning how to build a speaker box allows you to customize the fit and design of the box to match your desired audio quality. The basic two-speaker box designs are sealed and vented. This article details how to build a sealed speaker box, which separates the front and rear sound waves to improve the bass.Determine the size of the speaker box.Reference the speaker’s template to find the speaker’s measurements.The template is included with the rest of the basic speaker information upon purchase. If the template can’t be found, contact the manufacturer for the information or measure the speaker yourself:Figure the depth (front-to-back dimension) of the speaker box by adding 2 inches (5 cm) to the depth of the speaker.Use the speaker’s height and length measurements as the box’s internal height and length dimensions.Multiply the depth, height and length to determine the internal volume of the box.
Adjust the measurements as needed until you reach the recommended range
Step 10: Assembling
Place the speaker in the box and check that it fits.Hook up the speaker wires.Cover the back, top and bottom of the speaker box with 1 inch (2-1/2 cm) of poly fill to minimize resonance.Insert the speaker and run the connectors through their appropriate holes.Secure the speaker with screws through the mounting holes.Caulk any openings to ensure the speaker box is airtight.Allow the caulk to cure for 12 to 24 hours.Don’t construct a speaker box that has walls with equal dimensions. The shape diminishes the speaker’s effectiveness.
Step 11: CONNECTING TO MOBILE
FOR THIS YOU NEED AUX CABLE .AUX CABLES' FIRST AND SECOND SEGMENTS ARE OF ONE TERMINAL AND THE LAST ONE IS INDEPENDENT SO CHECK IT CARE FULLY AND JOIN THE TWO OPEN WIRES TOO THE AUX CABLE AND THEN YOU CAN SOLDER IF YOU CAN AND INSERT THE OTHER END IN MOBILE'S HEADPHONE PORT
Step 12: PLEASE VOTE!
IF YOU LIKE MY IDEA PLEASE VOTE AND MAKE IT AS FAVORITE I AM ALREADY HAVING A DREAM FOR THIS TO GET FEATURED PLEASE HELP!
