AI Technical Summary

Technical Problem

In existing ear-worn hearing devices, due to space constraints, it is difficult to effectively integrate components such as sound transducers, wireless transceivers, audio processors, batteries, and microphones, resulting in limitations on the overall size and performance of the devices.

Method used

An ear-worn hearing device has been designed, which adopts a transducer housing with a stepped end portion, including a stepped end portion and a diaphragm. Combined with flexible circuitry and electrical terminals, it integrates the sound-generating transducer with electrical components. The stepped end portion reduces the size of the device and provides space to accommodate other components.

Benefits of technology

It enables the efficient integration of multiple components within a limited space, reducing the size of the device while maintaining sound output, and providing more space to accommodate other electro- or mechanical hearing device components.

Abstract

The utility model relates to an ear-worn hearing device. The apparatus includes a receiver having a transducer housing, the transducer housing having a stepped end portion. And one or more diaphragms disposed in the transducer housing and dividing an interior of the transducer housing into a rear cavity volume and a front cavity volume, the front cavity volume being connected to a sound port at the stepped end portion. The stepped end portion may receive a diaphragm inside the transducer housing and a hearing device component outside the transducer housing. A motor disposed in the transducer housing is coupled to the diaphragm and electrically connected to an internal or external electrical interface of the hearing device.
