Final answer:
Options for outputting sound from a computer include speakers, headphones, and sound cards. Sound is produced by the speaker cone vibrating and creating pressure changes in the air, which are heard as sound waves.
Step-by-step explanation:
Some options for outputting sound from a computer device include speakers, headphones, and sound cards. These devices are designed to convert digital audio signals from the computer into audible sound waves that we can hear. Among these options, the correct answer to how sound is produced by an electronic speaker is: The cone of a speaker vibrates to create small changes in the pressure of the air.
When the audio signal is sent to the speaker, it goes through an amplifier and then to the speaker's transducer, which converts the electrical energy into mechanical vibrations. These vibrations push against the surrounding air, creating pressure waves that propagate through the medium. This action is what generates the sound we hear. To experience and experiment with these principles, one could utilize a CD player or portable electronic device connected to speakers, turn on the sound options in an experiment setup, or choose the proper microphones for production depending on the sound quality required.
