1. An electronic device, comprising:
a plurality of switching elements configured to:
apply, from a direct-current power supply, a voltage to a first end of an electroacoustic converter based on a first pulse signal, and
apply, from the direct-current power supply, the voltage to a second end of the electroacoustic converter based on a second pulse signal, wherein the electronic device is configured to perform wireless communication based on a communication frequency; and
a delay circuit configured to generate a delay, based on the communication frequency, in at least one of the first pulse signal or the second pulse signal.
