Bone conductor headphone, ideal if you have problems using regular headphones

Description

The name of the project is in honor of Stephen Colbert, who has a similar external ear formation.

This is custom designed for a collegue that has a special formation in the external ear, that makes it unconfortable or impossible to wear all types of headphones available on the marked; with the particularity that it prevents the user from listening to stereo audio recordings.

Here we use a bone conductor, which uses bone as a medium for audio waves, in such a way that the patient pushes the device against the head or skull and hears the audio that is transmitted to the internal ear.

This is just a quick prototype and proof of concept, with the next versions focussing on usability and portability, as well as using a cheaper battery charger.

Components

This project has no code what so ever and can be put together by just soldering together the components in the BOM.

colbert_headphone's Issues

Agregar modo micrófono

Para el paciente No. 2 es posible que necesitemos un micrófono que capte el ruido ambiente, de forma que pueda transmitir dicho audio a la salida del bone conductor.

Se mete mucho ruido ambiente

Sin un audífono para el auricular izquierdo. Paciente #1 pide auricular de audífono tradicional para lado izquiero, manteniendo el bone-conductor en el derecho.

Batería se apaga

Con el modulo de batería actual, el dispositivo se apaga algunas veces.

Probar con módulo más pequeño, y si el problema persiste, ensamblar los componentes en caja.

No funciona en celulares

Verificar el conector de audio que estamos usando, y ver si necesita algo especial para que funcione en celulares.
