Wi-Fi enabled smart speakers are generally powered by a 5V wall adapter via a USB type connector, or two pin jack plug, and over-voltage protection against incorrect or third-party adapters may be required. The internal system processors, and audio components may require additional voltage supplies both higher and lower than the supplied adapter voltage and therefore will require multiple step-up or step-down DC-DC converters.
