Provided are a light source structure and a light-emitting device. The light source structure includes a power supply unit, a field effect unit and a light-emitting unit, wherein the power supply unit supplies power to the field effect unit and the light-emitting unit; and the field effect unit includes a vibrator unit that receives sound waves from the outside to generate vibration, so that the field effect unit generates a current varying along with the vibration, and supplies the varying current to the light-emitting unit to generate light with variable light intensity.
