1. An electronic device, comprising:
a speaker configured to produce sound output;
a substrate;
strain gauges on the substrate each of which has resistors in a bridge circuit;
light-emitting diodes on the substrate; and
a light-transparent and sound-transparent cover layer that covers the strain gauges and the light-emitting diodes, wherein the strain gauges are configured to gather a force measurement on a force applied to the light-transparent and sound-transparent cover layer and wherein the speaker is configured to adjust the sound output in response to the force measurement.
