The audio signal (alternating current) is passed through the conductive voice coil. So how does the moving-coil dynamic transducer work?

In the case of speakers, the driver is held within an enclosure. In the case of headphones, the driver is held within the ear cup or earbud (headphones vs. To learn more about the role of magnets in headphone design, check out my article Why & How Do Headphones Use Magnets? This magnetic structure has a cylindrical cutaway just big enough to allow the conductive coil to be suspended within it without the two components ever touching each other. The oddly-shaped magnet is achieved by using pole pieces to extend the magnetic poles in specific places. The direct coupling of the coil and diaphragm means that as the coil moves, the diaphragm does as well. This voice coil is attached to a thin (typically circular) diaphragm. The voice coil is made of tightly wound conductive wire (typically copper) wound in a cylindrical form. WeвЂ™ll get to that in a second.ДЇirst, letвЂ™s briefly go over the design of the moving-coil driver. This concentrates the magnetic field around the coil, which improves the driverвЂ™s efficiency as a transducer. We also notice that this over-simplified diagram shows opposite magnetic poles to the immediate interior and exterior of the voice coil.

The Sennheiser HD 280 Pro (link to check the price on Amazon)В is a headphone with two drivers.Д¬ross-Sectional Diagram Of A Moving-Coil Dynamic DriverДЄs we see above, there are 4 key components to the moving-coil headphone/speaker driver: The left headphone driver will reproduce left channel audio as sound, while the right headphone driver will reproduce right channel audio as sound. Each driver typically accepts one channel of a stereo audio signal.

#How to turn headphones into speakers drivers#

Headphones nearly always have two drivers (hence the plural nature of the name вЂњheadphone(s)вЂќ). Without a driver, a headphone or loudspeaker would not be able to produce sound. The transducer elements of a headphone or a loudspeaker are known as drivers. The answer can be found by learning about their drivers.Дrivers: The Transducer Elements Of Headphones & Speakers So we know that headphone and loudspeaker transducers turn audio signals into sound, but how do they do so, exactly? How do headphones and loudspeakers work as transducers? However, this is not always feasible for various reasons due, in large part, to discrepancies in the frequency response of the transducers.ДЇor more information on headphone frequency response, check out my article What Is Headphone Frequency Response & What Is A Good Range? Ideally, the loudspeakers and headphones will reproduce the audio signal as precisely as possible.

We see the sinusoidal waveform with a maximum voltage (peak amplitude) above the zero line (horizontal dotted line) and a maximum negative voltage below the zero line.ДЄgain, the role of the loudspeaker and headphone is to convert analog audio signals into sound waves.

Their amplitudes are defined by an AC voltage that oscillates between positive and negative values.Д«elow is a simple illustration of a 1 kHz single-frequency analog audio signal. Analog audio signals are continuously variable alternating currents. The electrical energy is found in the audio signal. Note that microphones are also transducers that perform the opposite conversions, turning sound waves into audio signals.ДЇor more information on microphone transducers, check out my article How Do Microphones Work? (The Ultimate Illustrated Guide). In the case of headphone and loudspeaker transducers, electrical energy is converted into mechanical wave energy. In this article, weвЂ™ll discuss headphone and speaker transducers in greater detail and describe the driver designs that allow these audio devices to produce sound for our listening pleasure (or displeasure).ДЄВ transducerВ is a device thatВ convertsВ energy from one form to another. They have drivers that use various working principles to turn the alternating current of audio into diaphragm movement and sound production. How do speakers and headphones work as transducers? Headphones and loudspeakers are designed to convert electrical energy (in the form of audio signals) into mechanical wave energy (in the form of sound waves).

Speakers and headphones are common transducers, and knowing how they work will help us better understand the world of audio. If youвЂ™ve been studying audio and sound, youвЂ™ve likely come across the magical term вЂњtransducer,вЂќ which refers to devices that convert one form of energy into another form of energy.
