Balanced-armature audio receivers for hearing-aid designs
Measuring 80mm3, the receivers provide up to 20% space savings versus similar competitive products and up to 75% conpared to dynamic receivers. The technology also offers substantially more sound output per unit size and cleaner mid-range sound compared to dynamic-style receivers, Molex claims.
The balanced armature receivers are customisable, allowing OEMs to adjust impedance or other specifications to meet specific requirements. Besides applications in hearing aids, balanced armatures can be used for Cardiac Rhythm Disease Management (CRDM) devices where they can also more efficiently transform energy into sound, helping to save or extend battery life. In addition to hearing aids, the technology is ideal for the premium in-ear earphone market where manufacturers are looking to design higher-performing, smaller and more attractively-designed earphones.
