L'objectif de ce projet est de réaliser une barre de son DIY compatible Dolby Atmos. Pour cela, la barre de son exploitera des architectures de chez Texas Instruments, à la fois pour le processeur audio et la carte d'amplification.
Travaux à réaliser :
- Ajouter un processeur prenant en charge la communication Bluetooth et Wi-Fi.
- Trouver une méthode permettant de basculer entre différentes sources audio.
- Concevoir l'architecture globale du projet (gestion des différentes cartes, intégration dans le boîtier, etc.).
- Concevoir la carte d’alimentation.
- Concevoir la carte d’interface.
Travaux réalisés :
- Reprise du schéma de la carte d’évaluation EVMK2GX de Texas Instruments pour le processeur 66AK2G12 → Processeur_Barre_Son_Avant_Projet.
- Reprise du schéma de la carte amplificateur audio TIDA-01414 utilisant les amplificateurs TPA3244 → Amplificateur_Audio_Avant_Projet.
- Reprise du schéma de la carte fille audio K2G → Audio_Carte_fille.
The objective of this project is to build a DIY Dolby Atmos-compatible soundbar. To achieve this, the soundbar will use Texas Instruments architectures for both the audio processor and the amplifier board.
Tasks to be completed :
- Add a processor supporting Bluetooth and Wi-Fi communication.
- Find a method to switch between different audio sources.
- Design the overall architecture of the project (management of the different boards, integration into the case, etc.).
- Design the power supply board.
- Design the interface board.
Completed tasks : -Recreated the schematic of the Texas Instruments evaluation board EVMK2GX for the 66AK2G12 processor → Processeur_Barre_Son_Avant_Projet. -Recreated the schematic of the audio amplifier board TIDA-01414 using TPA3244 amplifiers → Amplificateur_Audio_Avant_Projet. -Recreated the schematic of the K2G audio daughter card → Audio_Carte_fille.
