3.5mm Stereo Switching Headphone Jack
The internal speaker circuit relies on a physical leaf-spring contact inside the headphone jack to complete the signal path. If this contact becomes bent, oxidized, or stuck in the open position, the amplifier cannot deliver current to the internal speaker. Replacing this PCB-mounted component restores the mechanical bridge required for speaker operation.

Internal 40mm Mylar Speaker Transducer
The small internal speaker utilizes a high-excursion voice coil that can fail due to thermal stress or physical displacement if the unit is driven at maximum volume for extended periods. A break in the voice coil wire results in an open circuit, rendering the speaker non-functional despite the amplifier and logic board working correctly.

Main Logic PCB Assembly
The logic board contains the Class-D audio amplifier and the digital-to-analog converter (DAC) for the internal sound engine. A failure of the amplifier IC or the power delivery rails specifically for the audio section would prevent any signal generation to the speaker, though this is less likely if the screen and MIDI functions remain active.
