Effect. This wave reaches and moves your eardrum. Which sends a signal that your brain interprets as sound you could even say that hearing is just movement detection.

Speakers work by converting electrical energy into mechanical energy (motion). The mechanical energy compresses air and converts the motion into sound energy or sound pressure level (SPL). When an electric current is sent through a coil of wire, it induces a magnetic field.

Alexa devices need a WiFi connection to function properly. When you ask Alexa a question or use a voice command, an audio recording is sent to Amazon's cloud over your WiFi network. Then it is processed and sent back to your device over WiFi so Alexa can answer your question or fulfill your request.

With Alexa, you can make hands-free voice or video calls to anyone who has a supported Alexa-enabled device or the Alexa app. On Alexa-enabled devices, you can even use services like Zoom, Chime and Skype. Call up to 10 phone numbers in the US/UK/CA/MX (emergency numbers are not supported).

Loudspeakers use one or more electromagnetic motors (usually called drivers) attached to a cone to broadcast sound waves. Speakers must be attached to another electronic source, which sends a signal that is programmed to replicate specific sound waves.
