Lisle, Ill. – Molex Inc. has introduced a series of balanced armature audio receivers that delivers up to a 20 percent space savings versus similar competitive products, and up to 75 percent savings compared to dynamic receivers. Measuring 80-mm3, the balanced armature receivers are suitable for the hearing-aid market.
In addition to the small size, the balanced armature technology is said to offer significantly more sound output per unit size compared to dynamic types. Molex said this is an advantage in miniaturized applications where several receivers are used to produce different functions such as tweeter, mid and bass tones. The technology also is said to produce a cleaner mid-to-high range sound than dynamic receivers. These types of devices are also preferred in applications where battery life and size are critical parameters, according to Molex.
These devices may also be used in cardiac rhythm disease management devices, "where they can also more efficiently transform energy into sound, helping to save or extend battery life," as well as premium in-ear earphones that require higher performance, smaller size, and a more attractive design, said Molex.
The balanced armature receivers are customizable, allowing OEMs to adjust the impedance or other specifications to meet specific requirements.
"Many people who need a hearing aid don't pursue getting one because they think it will be a big, uncomfortable device," said Anthony Kalaijakis, strategic medical market manager, Molex, in a statement. "By combining our precision manufacturing capabilities and audio business expertise, we provide audio OEMs with the ability to cost effectively design products half the size of traditional hearing aids yet with superior sound output and quality."
