When the speaker pushes forward and creates a change in sound pressure, it simultaneously creates an equal but opposite sound pressure to its rear. However, thereвЂ™s an issue that needs to be addressed.

To learn more about speaker drivers and their role as transducers, check out my article How Do Speakers & Headphones Work As Transducers? This is effectively how the speaker acts as a transducer and converts electrical energy (audio signals) into mechanical wave energy (sound waves). The opposite is true as the cone/diaphragm pulls backward. The audio signal (AC electrical signal) applied across the driverвЂ™s conductive element (voice coil) causes coinciding movement in the driverвЂ™s cone/diaphragm.ДЄs the cone/diaphragm pushes forward, it compresses the air in front of it and rarefies the air behind it.

LetвЂ™s imagine a speaker driver for a moment.Д¬ross-Sectional Diagram Of A Typical Speaker Driver The answer has to do with phase cancellation and the enclosureвЂ™s ability to mitigate the loss of sound wave cancellation. So why are practically all speakers designed with enclosures? The fact that practically all speakers have enclosures should tell us how important they are to speaker design. Why Do Practically All Speakers Have Enclosures?

In this article, weвЂ™ll be discussing enclosures as being separate. That being said, some regard the enclosure as being the entire housing unit of the speaker. Note that the enclosure is typically considered separate from the speakerвЂ™s housing that contains the speakerвЂ™s other components (crossover networks, amplifiers, inputs/outputs, EQ, etc.). They range from simple sealed particleboard boxes for small drivers in home stereos to incredibly complex systems with internal baffles, horns, bass reflex ports and acoustic isolation that house multiple large-diaphragm drivers for concert-grade sound reinforcement. Speaker enclosures come in a wide variety of shapes and sizes. Enclosures a meant to deal with the rearward sound waves produced by the speaker driver(s). In fact, it is essential for optimal speaker performance in nearly all speaker models.ДЄ speaker enclosure is essentially a small hollow box that interacts with the rear of the speaker driver. Though that is one function of the enclosure, this seemingly simple box-like structure is much more important than that. WeвЂ™ll also touch on the various enclosure types.ДЄ speaker enclosure may resemble a box structure that houses the speaker drivers. So, then, why do practically all loudspeakers utilize enclosures? This article will answer this question in detail, going over each of the reasons for the inclusion of an enclosure in speaker design. Speaker enclosures have a great effect on the speakerвЂ™s sonic character and are largely required to mitigate phase cancellation at lower frequencies. Why do loudspeakers need enclosures? The truth is that speakers do not absolutely require enclosures to act as transducers, but nearly all utilize enclosures to improve performance.

To fully understand how speakers work, we must understand why they are designed into such enclosures and whether enclosure design is a major factor in loudspeaker performance.

The Adap has a higher resonance frequency.Seeing a speaker driver by itself seems to be a rare occurrence as the vast majority of speakers are designed into boxes known as enclosures. It is optimized as a tweeter with high SPL above resonance. In free-field, the resonance is lower than Adap, which allows a lower crossover frequency.ДЄdap is a MEMS-based micro-speaker for occluded-ear headphones and can also be used as micro-tweeter for wearables and array applications. This speaker provides higher excursion and more damping ideal for in-ear designs. It can also be used as a micro-tweeter for wearables and array applications. The perfect addition to traditional speakers, they can be easily retrofitted into standard enclosures to improve treble or implement 3D audio systems.ДЄchelous is a MEMS speaker designed for occluded-ear headphones. USound GmbHвЂ™s Ganymede Achelous and Adap MEMS speakers with their compact size of 4.7 mm x 6.7 mm x 1.6 mm are ideal for in-ear headphone designs and wearables such as true-wireless headsets.
