How to Build a Simple Speaker
- Step 1: A Little Technical Background Knowledge on How Speakers Work.
- Step 2: Acquire Parts and Tools.
- Step 3: Start Building.
- For this step, you will need the Index Card, Speaker Basket, Electrical Tape, and Wire.
- For this step, you will need your Coil and Plate.

What is a speaker circuit?
A speaker consists of a baffle connected to a coil of wire wrapped around a magnetic core. When electricity is passed through the coil it will move, pushing or pulling the baffle, which in turn moves air and produces an audible sound. Speakers are very low resistance and so require capacitors to block the DC current.
How do you make a speaker with a magnet?
Wind up a coil of wire, attach it to the bottom of a paper cup, hold a magnet nearby, and listen to the radio! You’ve made your own speaker.
Can we make speaker without magnet?
A lightweight speaker is constructed without permanent magnets by providing two coils, one of which is mounted on a movable membrane and the other of which is mounted on a fixed frame. One of the coils is fed with an excitation signal directly from the source.
What colors are speaker wires?
The color code for four-conductor wire is speaker one: Red (positive), Black (negative) speaker two: White (positive), Green (negative). Its purpose is to carry an electrical signal (voltage and current) from the amplifier (or the amplifier section of a receiver) to the speakers.
Can you make passive speakers active?
In order to turn a passive speaker into an active one, you have to run the speaker through an external power source and amplifier. This amplifier is often seen in the form of a pedal activated on a pedalboard to provide additional power. This pedal can be activated for the instruments.
Can I connect passive speaker to active speaker?
You can combine and connect passive speakers with powered speakers using the standard connection (Red/Black) or bi-wiring using the appropriate twin cables. Powered speakers consume a lot of power, so people often hook up passive speakers to powered speakers to ensure that they don’t overwhelm the power supply.
How does a simple speaker work?
Speakers work by converting electrical energy into mechanical energy (motion). The mechanical energy compresses air and converts the motion into sound energy or sound pressure level (SPL). When an electric current is sent through a coil of wire, it induces a magnetic field.
What can I do with a simple speaker circuit?
This is a very simple project in which you put together a simple speaker circuit that can work with any standard speaker jack such as on a computer or a CD player so that you can hear sounds from these devices.
What can you do with a wireless speaker?
The article explains a very simple circuit of a wireless speaker system which can be used for playing hi quality music wirelessly from your TV set, DVD player, Ipod, cell phone or from any music system.
Why do you need amplification for a speaker?
Although speakers do not need power in order to work, they do need amplification. This is why it must be plugged into a speaker jack, which is equipped internally to provide amplification to the speaker so that it can play out sound with enough volume for a user to hear. So great, you now know how to build a simple speaker circuit.
How do you make a microphone to speaker circuit?
Construct the circuit in a Veroboard. PCB is a good choice. Remove the R2 and use a potentiometer to adjust the gain of the microphone. Connect a long wire across Speaker and keep it at larger distance from the microphone. The feedback will be lower. Use additional filters to get clean sound output.
