Abstract

A cochlear implant system includes: an electrode array implanted within a cochlea; an internal processor in communication with the electrode array; an implanted antenna which is electrically coupled to the internal processor; and a modular external headpiece which is removably positioned over the implanted antenna, the modular external headpiece including a core containing a sound processor for processing sound and providing a corresponding signal to the implanted antenna; and a modular component configured to releasably engage the core and supply electrical power to the core. A modular speech processor headpiece includes a core comprising a microphone and sound processor for producing a signal representing ambient sound to be transmitted to a cochlear implant, the core further comprising a number of electrical contacts; and a modular component containing a number of electrical contacts corresponding to the electrical contacts of the core; wherein the core is configured to engage with the modular component such that electrical communication is made between the core and the modular component.
