Knowles drivers

With a few rare outliers excepted, there are two different types of earphone drivers: dynamic drivers and balanced armatures. Although great earphones have been made with either type of driver, and often contain both types, the two drivers are very different in form and performance. Most headphone enthusiasts understand the concept of dynamic drivers, which are basically just miniaturized versions of conventional speakers, but many do not understand how balanced armatures knowles drivers, or what their advantages and disadvantages are. Hugh Knowles invented balanced armatures in to serve the hearing-aid market, and the company he knowles drivers, Knowles Electronics, remains the leading supplier.

Knowles drivers

Knowles is the leading manufacture of balanced armature drivers. These drivers, originally developed for hearing aids and other critical listening applications, offer improved fidelity, realism and detail over traditional dynamic drivers. They are incredibly small and lightweight, and provide greater output with less power. Balanced armature drivers use an electronic signal to vibrate a tiny reed that is balanced between two magnets inside a tiny enclosure. The motion of the reed is transferred to a very stiff aluminum diaphragm. This diaphragm is free of unwanted resonances in the audio band, allowing it to produce excellent clarity. Balanced armature drivers are incredibly small. This leaves more room for other components or a larger battery inside hearable devices, and can allow multiple drivers to be combined to get the best sound and performance from in-ear monitors or wireless earphones. A balanced armature driver can also be combined with an existing dynamic speaker in what is commonly called a hybrid earphone. In this configuration, the balanced armature drivers focus on the critical high-end portion of the audio spectrum, bringing a new level of clarity and realism.

Balanced armature drivers. Premium audio in a tiny package. In wired or wireless earphones, balanced armature drivers are small enough to replicate the performance of premium loudspeakers by allowing separate woofers, mid-range drivers, and tweeters to be combined in a single package. As an audio pioneer and global leader in balanced armature receiver design, Knowles collaborates with leading brands globally to deliver exceptional premium audio experiences. What is a balanced armature?

Despite their tiny size, balanced armature drivers offer incredibly detailed and accurate sound. Their thin, lightweight diaphragms are highly responsive for unprecedented clarity. Designers of modern hearables must balance sound quality and features with comfort, discreet appearance, and battery life. Manufacturers of hearing aids have wrestled with these issues for decades. It is no coincidence that virtually all of the world's hearing aid companies have chosen balanced armature drivers for their devices. Small enough to fit in the ear tip, balanced armature drivers allow more room in hearables for sensors, additional features, or a larger battery, without sacrificing comfort. Their high efficiency means longer battery life in the coming next generation of hearables as they do for hearing aids today.

However lots of money goes into research and development of the iems, building the crossovers, experimenting with different materials and configurations etc. They have virtually no economies of scale and their products cater to a niche market. That also applies to true wireless earphones, one area where our hearing-aid research spills over into consumer earphones.

If going the universal route, buying cheap pre-made shells that instantly drop the value of your IEM but whatever but then you'll have to research on what combination works the best and how to arrange it to fit a small volume. Nobody buys a loudspeaker with one driver in it -- even the new base model Amazon Echo announced a few days ago has woofers and tweeters in it. Joined Dec 11, Posts 28, Likes 47, Location.
