Translating step 25

Step 25
Like on the Sonys, these ear cushions clip to their cup housing. With a little spudger persuasion, they are free—effective, if not as elegant as the AirPods. Unlike the Sonys and the AirPods, the cloth liner over each speaker grille doesn't come up with the ear cushion. The L and R marked liners are slightly glued down, making them annoying to peel off without ripping. Under the liner, Torx security screws guard the entrance to each ear cup.

  • Unlike the Sonys and the AirPods, the cloth liner over each speaker grille doesn't come up with the ear cushion. The L and R marked liners are slightly glued down, making them annoying to peel off without ripping.

  • Under the liner, Torx security screws guard the entrance to each ear cup.

  • Both cups hold a mess of wires—but the right one, home to the main circuit board, is truly tangled.

  • On that circuit board lives a Qualcomm CSRA68105 Bluetooth audio SoC. Here are some full-res images of that board, if you want to do more sleuthing: front, back.

Comme sur le Sony, les coussinets sont clipsés à la coquille. Il suffit d'insister avec la spatule pour les détacher. Une solution efficace, mais pas aussi élégante que celle de l'AirPods.

Contrairement à ses collègues du Sony et de l'AirPods, le morceau de tissu qui recouvre la grille des haut-parleurs ne s'enlève pas en même temps que le coussinet. Les tissus marqués L et R sont légèrement collés en place. Les enlever sans rien déchirer est donc un peu délicat.

Juste en dessous, des vis Torx Security montent la garde à l'entrée des coquilles.

Chacune des deux est remplie d'une salade de câbles. Mais celle de droite, la demeure du circuit imprimé principal, est un véritable mic-mac.

Le circuit imprimé abrite un système sur une puce (SoC) audio Bluetooth CSRA68105 Qualcomm. Voici des photos haute résolution du circuit si vous avez envie de faire des investigations : recto et verso.
