Apple uses its own proprietary audio technology for the speakers in iPhones. While they may collaborate with other companies for specific components or manufacturing, the overall speaker design, tuning, and software integration are developed and controlled by Apple.
This means the speakers in iPhones are not made by companies like Bose, JBL, or Sony. They are designed and engineered by Apple specifically for the iPhone experience, ensuring optimal sound quality, clarity, and integration with other features like spatial audio.
