Replacement Loudspeaker Signal Flex Cable for iPhone XR – Logic Board to Bottom Speaker Audio Transmission Line

This replacement loudspeaker flex cable for iPhone XR is responsible for transmitting audio signals from the main logic board to the bottom speaker. It is not a speaker itself, nor does it improve audio performance, but it ensures the existing speaker receives signal. When the original flex is damaged or disconnected, this part can restore normal sound output. The shape, length, and connectors are all model-specific and should only be used in iPhone XR units. Each cable is tested for electrical continuity and connector integrity before shipment. Recommended for professional use, as replacing this component involves opening the device and reassembling components around it.
